Bridging the gap between the Humanities and the Sciences

So it's been a couple weeks since my last post. You know how it goes, classes ending, submitting grades, finishing papers, etc. And let's not forget the importance of taking a much needed rest from work!

Well, not too much is going on now . . . besides teaching the lab sections for summer courses and working on summer research projects. Anyways, the other day I was browsing the Edge website and came across this page celebrating the 50th anniversary of C.P. Snow's lecture on the "Two Cultures," that is the culture of the literary intellectual and the culture of the scientist. At the time, the two cultures were seen as divided camps of thinking. Those in the humanities were viewed as the true intellectuals (i.e., those in philosophy, literature/poetry, art, the social sciences, etc.). And the expectation was that scientists had very little to say about culture, the human experience, or human nature.

50 years later, Seed Magazine asked members of the "Third Culture" (i.e., those bridging the gap between the humanities and the sciences) whether the two cultures are still divided today. Visit the link and check out the videos. They're pretty good, and quite short (6-10 mins.). Overall, the answer seems to be that the two cultures are not as divided as once was and is more like a continuum from one pole to the other. Advancements made in the science of the mind have especially contributed to bridging this gap. It has helped changed how we think about those abstract concepts (e.g., human nature, religion, even beauty). As well, it is young scholars who are becoming more and more interested in collaboration among different fields of inquiry.

Below are the videos from Harvard psychologists, Steven Pinker and Marc Hauser. Enjoy!:

Why We Believe in Gods - Evolutionary Psychology and Religion

There was a lecture recently posted on richarddawkins.net (though I found out about it through pharyngula) that might be of interest for some of you.

It's a talk by Dr. Andy Thomson, (a psychiatrist from back home in Virginia!) concerning religion from the perspective of evolutionary psychology and cognitive neuroscience. It's quite a nice (and I think convincing) lecture. Essentially, his thesis is that religion is a cultural artifact or byproduct (like music) that has hijacked specific traits/modules in our brains that once provided a selective advantage for living in a social world (SCI anyone?). Of course, I cannot do his argument justice. You will have to watch it (if you haven't already) and decide for yourself. Though, remember, it's a normal academic talk . . . so it's about an hour long . . . but there's a brief Q&A near the end. The video is posted below, check it out and see what you think:






*************************************************************

By the by, if you are not all video-ed out and you have some interest in that work by Simon Baron-Cohen, which Thomson mentioned, then check this video from the Edge website out! Besides being the brother of Sacha Baron-Cohen, Simon is a brilliant psychologist from the University of Cambridge. His work mostly concerns research on autism and theory of mind. The talk posted on the Edge site is about his experiments on how people can read the emotional expressions of others just by looking at their eyes. Specifically, he's examining sex differences on whether women can read emotional expressions from people's eyes quicker than men.

Well, that's about it. There's your two for one! Enjoy!

self-presentation

This week’s readings on the self seemed to concern a more classic topic than previous weeks, and that is the idea of self-presentation. In general, we like to manage the impressions that we give to others. We like to appear favorable. As well, we’ll even manipulate the impressions of others to make them appear unfavorable. For instance, Gilbert and Silvera found that people will try to hinder others by “overhelping” them. If a target person that we do not favor is performing on a task that is rather simple, or easily performed, we’ll likely help this person achieve his/her goal in order to undermine his/her competence. So, in effect, the target person will seem incompetent because he/she received help on an easy task.

Not to sound repetitive, but self-presentation makes sense from an evolutionary perspective, especially if Kurzban’s idea of the self (the SCI) is an accurate representation of reality. If the self is a collection of modules that help us function in a social world, by manipulating others, then self-presentation fits in as one tool we use to manipulate others. As I stated before, we manipulate the representations of ourselves to appear favorable to others, and we manipulate the representations of others to make them appear less favorable. An important motive that seems to be behind self-presentation is belongingness and acceptance, but it is by no means the only motive. As the SCI would predict, the activation of multiple modules will differentially affect self-presentation. In support of this notion, Griskevicius et al. found that activating self-protection versus mating goals will differentially affect whether we conform to a group or not. When people are primed with self-protection goals, they generally conform to group attitudes/norms. This is because fitting in with groups often proved to be beneficial for protection. At the same time, priming men with mate goals will make them less likely to conform to group attitudes, as being perceived as independent and differentiated from the group could potentially lead to greater reproductive success. Women on the other hand were more likely to conform, as agreeableness is often cited as a sought after quality from men. I do wonder which goal would have precedence over the other though. If self-protection and mate goals were each activated simultaneously, how would that affect conformity? Would people be more likely to conform because self-protection goals are stronger?

We also learned that self-presentation seems to depend on self-regulatory energy. It takes energy to control our self representations, as well, when our energy has been depleted, we are less likely to control them. Interestingly, representations that are familiar (overly practiced) do not deplete regulatory energy. For instance, obeying gender rules is usually familiar to us, so it doesn’t take energy to obey them. This is very reminiscent of the formation of implementation intentions, and lends support to the notion that perhaps forming implementations intentions will not endanger one to becoming thoroughly depleted. Thinking back on the Griskevicius work, it must take energy to not conform to group behavior. Will the activation of mate goals be hindered by regulatory depletion? Or will the mate goals be so familiar that their effects on self-regulation be minimal? Just some questions to think about I guess.

Social Neuroscience and the Self

The studies from this week’s readings examined the self from a social neuroscience perspective. There were some pretty interesting findings in general, but I think the most important implication of all the studies is that the “self” can be linked back to physical/biological structures. For instance, Gailliot (along with my advisor and their colleagues) observed that acts of self-regulation actually deplete blood glucose levels. And Kelley et al. even found that self-referential (comparing traits to ourselves) thought is related to the deactivation of unique areas of the brain (the medial prefrontal cortex). It’s possible that this area is related to the processing of unique self-knowledge. These findings help remove the self from just being some abstract, theoretical concept, and instead shows how the self is linked to our evolutionary development.

We can also view threats against the self through brain imaging. Eisenberger et al. have shown that social exclusion is linked with activation of the same brain areas that are activated for physical pain. This has significant implications for how important belongingness was for us during our evolutionary development. Our social pain system has co-opted the physical pain system. When we feel exclusion, we really feel pained. It makes sense. Not only is having one pain system suited to deal similarly with physical and social pain more efficient/resourceful, but feeling pained after exclusion is a good way to motivate one to avoid social exclusion. It’s likely that those early humans who were not motivated to avoid exclusion were at a significant survival disadvantage. I think that this also goes in hand with Kurzban’s perspective of the self, in that the self-system evolved in order for us to succeed socially. I wonder then if those self-referential areas (the MPFC) in the brain developed at the same time as when the social pain system started to co-opt the physical pain system.

Another cool finding came from Neiss et al., who were able to link the relationship between self-esteem, executive function and negative affect to genetic influences. Generally, they found that people with low self-esteem had greater negative affect. As well, people with low executive function (self-regulation) had greater negative affect. And they also found that the relationship between self-esteem and affect mediated the self-regulation/affect link. Lastly, genetic factors accounted for a significant portion of variance (38 - 44%) in self-esteem, executive function and negative affect, though the largest contributing factor was due to the non-shared environment. Overall, they concluded that the executive self did not display a genetic or environmental link with negative affect above that shared with self-esteem. This makes sense to me from the sociometer/SCI perspective as well. If we developed our sense of self as a means for succeeding socially, and our self-esteem acts as a guage for our social worth, then negative feelings that come out of an inability to self-regulate should only arise when the regulation issue is connected to social worth (which will be gauged by the self-esteem). So when our self-regulation is low, and we have increased negative affect, it should be because our self-esteem is low too. Very cool.

There is one comment that I have wondered about though. They stated that genetic influences explain 30 – 50 % of the variance in self-esteem usually. I wonder what implications this has for the sociometer hypothesis. If self-esteem is just a guage for our social worth, then I would hypothesize that most of the variance in self-esteem (if not all) would be explained by non-shared environmental factors (i.e., whether we’ve been threatened with exclusion).

the implicit self

This past week’s readings on the self concerned the implicit or automatic self. The implicit/automatic self are those self-evaluations and goals that are most practiced and evaluated. Those representations are activated so often that they eventually become ingrained into the unconscious and become automated. This idea of the implicit self is related to the concept of the adaptive unconscious. We do not have the cognitive resources to deal with all the stimuli that we are presented with in our environment. Instead the unconscious takes on much of the workload.

It seems that much of our behavior is guided by goals that are outside of our conscious awareness. Once non-conscious goals are activated by the outside world, we are motivated to pursue those goals. Take the above picture for example. Cats are predatory animals and often like to attack birds among other things. This goal is activated so often that it's unconscious (and in the cat's case, probably instinctual). Nonetheless, when the cat's goal of attacking birds is activated, it strikes, even though the chicken (or rooster or whatever) is so much bigger. This is just an example that I'm using, but that's pretty much how non-conscious goals work for humans. Activation of non-conscious goals even help us persist in the face of obstacles. Such evidence seems to support the prior argument for forming implementation intentions.
For implementation intentions, one would form and practice a self-regulation goal until it is automated. Then once that goal is activated, he/she would be guided to pursue that goal (self-regulate). This idea is even more interesting, after reading up on non-conscious goal pursuit. If non-conscious goals are formed when one does not have the cognitive resources to pursue the goal consciously, and they make you persist in the face of obstacles, then perhaps implementation intentions really do have a minimal effect on regulatory resources. Though, I still think that it would take some energy to complete the goal and am not convinced that non-conscious goal pursuit would not deplete self-regulatory resources at all.

On another note, our implicit associations seem to have a strong effect on our behavior. For instance, for the most part, we like ourselves, so much so that we hold positive implicit self-associations. These associations make us favor things that resemble the self. People are more likely to live in cities that resemble their names. We’re more likely to favor people who have the same birthday as us. We’re even more likely to prefer teas, crackers, chocolates, etc. that share letters with our names. Additionally, when our self-worth is threatened, we compensate by having higher implicit self-esteem.

The implicit self is separate from the explicit self. In fact, Rudman et al. explained that “the picture that emerges is not of a unitary self, but of one composed of multiple subsystems that can operate in tandem or apart.” This is very interesting to me. It is remarkably similar to the Social Cognitive Interface theory of the self, which states that the self is a collection of cognitive modules that help us navigate the social world, but their actions are outside of our conscious awareness. I think the evidence from the research on implicit egotism and self-esteem are congruent with predictions from the SCI perspective. It would make sense that we would unconsciously seek out, and prefer things that are similar to us. People who are similar to us are probably more likely to accept us. Also, often times when we are threatened, we unconsciously compensate by gaining in implicit self-esteem. This compensation leads to an increased intergroup bias. Essentially, we’ll be more likely to favor groups that we are a part of. This, again, makes sense from the SCI perspective. In the evolutionary past, if we were threatened, it would be better to seek out the groups that we belonged to for protection. Of course, this increased intergroup bias has negative social side-effects for groups we are not a part of. This is more of a problem in modern times because different groups live in such close proximity to each other now. I think this issue would be good to explore further.

Correlation or Causation?


So I just recently came across this webcomic called: xkcd. It's pretty cool. The comics are pretty good, plus they often include topics concerning science and math. I especially love the one above. It concerns correlation and causation, and what the difference is between the two. Unfortunately, very often people confuse correlation for causation. For instance, the eating of ice cream might have an association (be correlated) with hot weather. Perhaps the hotter it is outside, the more ice cream I eat. So, yes, we would say the eating of ice cream is correlated with hot weather. But it would be a mistake to conclude that ice cream causes hot weather, right?

Confusing correlation with causation is a problem that occurs all the time, especially in the media (for instance, I found one headline stating that "TV Raises Blood Pressure in Obese Kids," when only a strong association between hours of tv and hypertension was found). If you are interested, here's a website that keeps a long list of news articles that confuse correlation with causation, plus some resources related to the issue.

As well, if you are in psychology, the following two links may be of great interest, that is, if you're looking to increase your expertise in the application of statistics to the field:

Evaluation, Measurement, and Statistics - This is Division 5 of the American Psychological Association.

Summer Statistics Workshop - Dr. Alan Reifman has put together a list of resources for various summer statistics trainings meant for researchers in the soical sciences. These trainings are held at a variety of institutions. This looks like a very good resource.

On an unrelated note, I have a new blogging buddy. Another one of my fellow graduate students, Dave, has started a blog about Somalia, called Somalfocus. If you have an interest in what's going on in Somalia, or perhaps in internaltional relations in general, then you should check it out.

Lastly, I'm running a little late with my next "Self" post. It will probably be up in the next day or two.

Self-Regulation

Last week’s readings on the self covered the topic of self-regulation and motivation. Self-regulation is essentially the ability to deliberately control our own behavior. Self-regulation has an adaptive quality to it. For instance, it would seem beneficial for one to be able to control one’s impulses, and plan for the future. And indeed, as Mischel et al. (1989) has found, children who are better at self-regulation often have better outcomes later in life, such as in academics.

Even though self-regulation is very beneficial, it seems to come from a limited resource. It’s like a muscle, and as you use it, it tires. As Baumeister et al. (1998) has shown, self-regulatory acts deplete the “ego,” thereby making one less able to self-regulate in the future. Self-regulation seems to require energy (i.e., glucose) and/or a resting period. It’s a good thing to keep in mind, I think.

Interestingly, conscious thought isn’t exactly needed for the initiation of self-regulation. Through “implementation intentions”, one can automate self-regulation for various goal pursuits. For instance, if one desired to be less prejudiced against the elderly, then one could train him/herself to “tell” him/herself not to consider a person’s age every time an elderly person is encountered. One thought that came to mind, after reading about this, is whether automating self-regulation uses less ego resources than directed self-regulation. In particular, when thinking of the concept of the adaptive unconscious from the prior articles, it seems that the automatic unconscious is useful and adaptive for its ability to take in a lot of information without using up our resources. So automated self-regulation might just take up less energy than consciously directed self-control. Yet it still seems as though directed thought is needed in sustaining the self-regulatory behavior. Only the initiation of self-regulation seems to be automated, and after training oneself to automate this behavior. If implementation intentions use ego resources as much as that of deliberate self-regulation, then I would think that such cueing could be detrimental to the self-regulatory ability. For instance, if one created implementation intentions for multiple behaviors, and one encounters many cues throughout the day that activate these intentions, then one could become quickly and thoroughly depleted. At what level would these implementation intentions become detrimental? Or does the mere training that automates this behavior build up self-regulation? So, perhaps the automation does deplete self-regulatory resources, but the practice of automating self-control built up a larger inventory of self-regulatory resources to take from? Thoughts to explore further perhaps.

Culture and the Self

This week’s readings on the self were pretty interesting. They were about the “cultural self.” Essentially, the readings discussed the different self-construals that can be found cross-culturally. As one might imagine, people within more individualistic societies are more likely to have independent self-construals, characterized by a focus on autonomy, uniqueness and internal attributes and emotions. Those from more collectivistic nations are more likely to have interdependent construals of the self. The interdependent self-construal is characterized by belongingness, self-in-relation to other representations, and a connection of the self to specific social contexts. Of course, this does not mean that people can’t vary within a society according to how independent/interdependent they are.

Markus and Kitayama’s review paper on the independent versus the interdependent self-construal was particularly thought provoking for me. I had a strong desire to connect their ideas to those from our past readings. If you really think about the interdependent self-construal, it fits in well with the Social Cognitive Interface (SCI) framework of Rob Kurzban, and especially with Leary’s sociometer theory. (I know, I know . . . . I seem to refer to these two theories a lot. What can I say?) Firstly, having an interdependent self-construal means that you define yourself in relation to your group members and the social context. You are constantly aware of and focus on the needs and desires of others within your in-group. And your basis for self-esteem is “the ability to adjust, and restrain the self, and maintain harmony with the social context.” This sounds remarkably similar to sociometer theory, in which it is theorized that self-esteem is a gauge for social acceptance. And according to the SCI, the self is a set of cognitive mechanisms that help us function socially, because belongingness was/still is very important for our survival. The interdependent self-construal seems to be the ultimate example of this, if the SCI perspective is valid. On the other hand, according to SCI theory, along with other past readings, the self makes up a story for you that may not be valid but will ultimately help you in the social world. I’m not sure if that’s happening here. To me, it seems that the SCI is not hiding itself (or it’s intentions) in those who have the interdependent self-construal. They are defining themselves in relation to their group members, and they know it. The SCI is telling a story. Whereas, for more individualist societies, belongingness is very important but it seems to be more of an underlying or unconscious value. This is where the SCI would work for us. I questioned: Do those with interdependent self-construals have more accurate self-knowledge?

And then I read Balcetis et al., whose research seems to support the notion that, yes people who are more interdependent also have more accurate self-knowledge. Yet, I do have questions about their dependent variables. It seems that the more collectivist a person was, the more likely he/she would accurately predict his/her future behavior. But each of those behaviors were pro-social in nature, and people who are more collectivistic may be more accurate in estimating pro-social behavior because it is very important to their self-concepts, thereby being more salient. I’d like to know if collectivists have more accurate self-knowledge in domains that are not related to sociality.

Nonetheless, in the grand scheme of things, it seems most of the world (outside of Western Europe and America) are more collectivistic. As well, these people have more accurate self-knowledge. This leads me to the following question: Is the individualistic/independent self-construal a relatively recent phenomenon (whether evolutionarily or culturally)? And what is the benefit of having an independent self-construal if it contributes to our inaccuracy in self-knowledge? We talked in class about how we probably have modules or at least the general capacities for both independent and interdependent self-construal. And these modules are probably activated differentially depending on the social context. There are circumstances where an independent self-construal would be best and vice versa. I think viewing such cross-cultural differences from the SCI perspective would be interesting to explore further.

the function of self-esteem

As you might notice, this past week’s readings were on the topic of “self-esteem.” Specifically the readings were focused on the function of self-esteem, the benefits of having high self-esteem, and whether we should focus policy on improving the self-esteem of children. A short review of the findings from the articles we read shows that self-esteem is often given a bit more credit than it may deserve. For example, high global self-esteem is not linked to improvements in performance (whether academic or not), although it is linked with persistence in the face of failure. As well, high self-esteem in the form of narcissism is linked with anti-social behavior. Those who have high self-esteem, but are also high in narcissism act more aggressive after an insult than those who are not high in both. Yet, this is not exactly an open and shut case. There are researchers on both sides of the issue that argue whether boosting people's self-esteem is good or not. Please see the Baumeister and Swann citations below for a good review on the debate.

At the moment I’m much more interested in the function of self-esteem than the effects of having high self-esteem, which brings me to the Greenberg article. Greenberg et al. (1992) proposed the “terror management” idea that self-esteem serves as an anxiety-buffer against things that threaten us, and specifically death. In three experiments, the authors showed that people with high self-esteem were less anxious than neutral others when threatened, and this effect was not due to positive or negative affect.

In their experiments, participants were essentially given false feedback on a personality or intelligence test. One group was given feedback meant to elicit feelings of high self-esteem, whereas another group was either given neutral or no feedback. Participants were then asked to watch either a graphic film clip (threat-group), or a neutral clip (no-threat) in one experiment, or, in the other two experiments, they were told that they would receive painful shocks (threat) or receive non-painful sensations from lightwaves (no-threat). The experimenters then measured how anxious the participants were, either by self-report or by physiological measures, such as sweating. They found that people who had high self-esteem were less anxious than low self-esteem individuals in the threat group. And the protection offered by self-esteem was not due to increased positive affect or decreased negative affect.

It’s pretty cool, but I’m still not totally convinced of the terror management interpretation of self-esteem. For instance, as mentioned earlier, the authors primed their participants in the threat condition by making them watch a graphic movie clip (depicting real deaths) or by telling them to expect painful shocks. The painful shock condition was employed as a way of testing the generality of the anxiety-buffer effect. But pain does not seem that far removed from feelings of mortality. Pain and death are often associated with each other, and both are strongly attached to our primal need for survival and safety. I’d like to know, instead, whether self-esteem can buffer against anxiety from weaker threats (e.g., a poor evaluation, a break-up). Additionally, this interpretation of self-esteem needs to be tested against other theories of self-esteem, such as Leary’s sociometer theory. As mentioned in an earlier post, sociometer theory posits that self-esteem acts as a gauge of social acceptance/rejection. When we are threatened with social rejection, our self-esteem should lower. This could then tell us that we need to adjust our behavior, so that we are accepted back into the group. Sociometer theory seems to work better within the evolutionary perspective of the Social Cognitive Interface (SCI).

If you remember, the SCI is a set of cognitive mechanisms that evolved with the purpose of helping us function socially. In essence, evolution has given us a sense of self so that we are better equipped for a social world. One in which staying connected with others is crucial for survival. Now, I am not saying that terror management theory (TMT) is resistant to evolutionary explanations for self-esteem. On the contrary, I think TMT works well within that approach. If self-esteem buffers against anxiety, then I think that would prove to be a very beneficial/adaptive function. But I do think that the sociometer interpretation works better within the SCI approach, than does terror management. Of course, this is assuming that self-esteem, and the self in general, only has one adaptive function and/or is not a by-product of some other cognitive mechanism. All in all, I think that terror management and sociometer theory can be reconciled with each other with-in an evolutionary framework. After all, isn’t death the ultimate form of social exclusion?

more blogging friends . . .

Well, I have some more blogging buddies out there.

I figured that I could link them here and add them to my blogroll, so that everyone who reads like a lake will have a chance to visit these new and exciting venues of the blogosphere.

First we have the blog, Ready, Set . . ., by some old buddies of mine, Joel and Nathan. It's mostly about their daily going-ons, comic inspiration, and progress on a cartoon/comic they are developing.

Next we have Intellectual Capital, by friend and fellow UK grad student Ryan. This blog concerns topics in social psychology and political/social commentary.

Lastly, we have Ridiculous Claims, by another grad student buddy, Tim. This one is for all you football nuts out there. And I mean American Football . . . not soccer . . . er, um, rest of the world football, haha.

Daniel Gilbert on TED

Harvard Social psychologist, Daniel Gilbert, recently had a talk posted on TED, though it looks like the talk was originally given in 2005.

It's good though. Gilbert is widely known for his research on happiness. What makes us happy? Can we predict future happiness? How do traumatic events effect our long-term happiness? And such.

Though related to his happiness research, this talk centered on general decision making (and specifically, erroneous economic decisions that we make). Basically, the gist of the talk is that people are notoriously bad in money matters because of two cognitive biases. The first causes us to make erroneous judgments in estimating the odds of a potential gain. The second causes us to make erroneous estimates in the positive value of the potential gain.

His reasoning for why we have these cognitive biases goes back to us being evolved creatures. Firstly, we evolved in environments that rarely changed. We lived in small groups, had short lives and had to make relatively few choices. Instead our ancestors focused on the here and now. In his words: "the highest priority was to eat and mate today."

Well, anyways, check out the video. It's good, and there's a Q&A section at the end.

Self-enhancement

This week’s readings were on the topic of “using the self.” Particularly, how do we evaluate ourselves, in what contexts, and the readings even examined self-fulfilling prophecies. When we make self-evaluations, do we search for accurate information? Or do we focus on what makes us feel better about ourselves?

Much of what I read pitted the self-enhancement perspective against the self-verification perspective. Self-enhancement is when a person focuses on positive central traits over negative ones. Self-verification, on the other hand, refers to preferring accurate information about the self, whether positive or negative. Essentially, it seems that people self-enhance more than they self-verify. For instance, we prefer accurate information about positive traits of ours over negative ones. We are also more likely to disconfirm negative traits that are central to our identity as opposed to those that are more peripheral. As well, we think our faces are more attractive than they actually are. And we would be quicker to pick out our face when morphed with an attractive face than when viewing our original face, or our face morphed with an unattractive face.

These self-enhancements that we make seem to be more related to implicit, unconscious processes (e.g., gut feelings) than more explicit, direct processes. As well, these self-enhancements are related to social comparison and self-perception processes. When people view us as more positive for a certain trait, we view ourselves as positive on the trait. And when we view others that are positive on a trait, we again self-enhance. Connecting themes, this idea goes back to the previous literature that we have read throughout the past couple weeks. Specifically, our self-concept is a story that our unconscious makes up about ourselves, and it may not be a true story. It’s hard to access accurate information about ourselves. Not much of our self can come from introspection and deliberation. Instead, it’s a story and we use that story to feel better about ourselves and to get along better with group members.

Steven Pinker and the Personal Genome Project

As many of you might already know, Steven Pinker (famous Havard psychologist) had his genome sequenced and posted on the internet for the Personal Genome Project.

Pinker wrote an essay about it for the New York Times, but I originally found out about it through edge. It's a pretty good essay. He covers genetic determinism, evolutionary theories for personality differences, and twin research. Genes do play out a large part in our behavior:

"Behavioral genetics has repeatedly found that the 'shared environment' — everything that siblings growing up in the same home have in common, including their parents, their neighborhood, their home, their peer group and their school — has less of an influence on the way they turn out than their genes. In many studies, the shared environment has no measurable influence on the adult at all. Siblings reared together end up no more similar than siblings reared apart, and adoptive siblings reared in the same family end up not similar at all. A large chunk of the variation among people in intelligence and personality is not predictable from any obvious feature of the world of their childhood."
But that doesn't mean that genes decide everything. You can make predictions based off genes that are flat out wrong (for instance, Pinker appears to have a gene that gives him an 80% chance of baldness). Much of it is probability, not only do you have to account for genes and the enivironment (i.e., nature vs. nuture), but you also have to account for how your genes interact with each other. Pretty cool stuff though.

Pinker went on the Colbert Report to talk about his genome sequencing experience as well. It's pretty funny, as can be expected. Check it out:

Self-Concept

This week’s “self” readings dealt with the idea of “self-concept.” Particularly, these readings covered the issues of how we discover/obtain our self-concept, and whether it is malleable to change. Before starting the readings, I was already suspicious of self-concept. This suspicion arose from the 2nd week readings on self-knowledge. As we learned last time, we aren’t very good at knowing ourselves (e.g., what motivates us, what predictions can we make about our future behavior, etc.). To me, before the readings, the idea of self-concept seemed to come from our self-knowledge. If we aren’t good at knowing ourselves, then how would we be good at discovering a stable self-concept? To tell the truth, I’m still not confident in the idea of self-concept after reading this week’s articles.

That’s not to say that self-concept is a bad thing though. Firstly, the mechanism behind self-concept seems to be a powerful encoding device. Our ability to recall information is greatly enhanced if that information is related to us (i.e., encoded through the self-concept). For instance, if I were presented with a list of words, I would likely remember those words that I felt described myself (e.g., Caucasian, music, happy, knowledge, etc.) than others (e.g., blonde, chair, suit, etc.). As mentioned last week, there is a lot of information out there in the “real world,” and much of it is processed by an adaptive unconscious. Perhaps this encoding ability of the self developed as a way for us to remember and act on important information.

Additionally, parts of the “self” are good at protecting us from the stresses of daily life. When we encounter stressful events, our self-concepts change, and this change has less to do with mood and more to do with the objective experience of the stress. We seem to describe ourselves with more negative attributes under stress than not. Yet components of the self help us cope with these events. Under stress, we rate our negative attributes as less important, we compartmentalize more so that we can focus on the positive, and we view ourselves as more complex. If we view ourselves as more complex, then we might have more positive attributes to focus on and activation of negative attributes won’t be needed.

Perhaps the most interesting aspect of the self-concept to me is what Goldstein and Cialdini call the “spy-glass self.” According to self-perception theory, we infer our self-attributes by observing the actions we carry out. Well, they go a step further. They posit, and found evidence, that when we identify with another person, we are likely to incorporate his/her attributes into our self-concept after observing this person’s behavior. So after participants are told that they have similar brain wave patterns as another person, and this other person is observed being helpful, then those participants will also be more helpful. I think this is particularly interesting for two reasons. Firstly, it goes back to the idea that self-knowledge is really just a story that we make up for ourselves, of the person that we think we are. But secondly, it reminds me of the Social Cognitive Interface view of self from Kurzban and Aktipis. According to this view, the self is a set of mechanisms that helps us negotiate the social world (e.g., helps us attain cooperation, acceptance, mates, etc.). It would then make sense that we would gain aspects of our self-knowledge by observing other people. It’s a widely known effect that we like things that are similar to us. If I incorporated attributes of another person into my self-concept, then perhaps I’ll increase my chances of acceptance, because I am now more similar to this person. I don’t know, it’s pretty cool though.
