Psychologists study pride and the difference between faking it and not.

Description of Paul Ekman's work on universal human expressions and microexpressions.

Intriguing article but frustratingly vague on the measurements used for intelligence testing. Apparently HARDI (High Angular Resolution Diffusion Imaging) can measure the diffusion of water through the brain, especially myelin. In yet another twin study (n=46 pairs) there appears to be a correlation between diffusion speed and intelligence.

The author conducted a partial replication of Stanley Milgram's (1963, 1965, 1974) obedience studies that allowed for useful comparisons with the original investigations while protecting the well-being of participants. (Abstract only for non-subscribers)

Where is the line between safety and paternalism? Two cases: food regulation and motorcycle helmets.

In this work, we address an important but unexplored topic, namely the neural correlates of hate. In a block-design fMRI study, we scanned 17 normal human subjects while they viewed the face of a person they hated and also faces of acquaintances for whom they had neutral feelings. A hate score was obtained for the object of hate for each subject and this was used as a covariate in a between-subject random effects analysis. Viewing a hated face resulted in increased activity in the medial frontal gyrus, right putamen, bilaterally in premotor cortex, in the frontal pole and bilaterally in the medial insula. We also found three areas where activation correlated linearly with the declared level of hatred, the right insula, right premotor cortex and the right fronto-medial gyrus. One area of deactivation was found in the right superior frontal gyrus. The study thus shows that there is a unique pattern of activity in the brain in the context of hate. Though distinct from the pattern of activity that correlates with romantic love, this pattern nevertheless shares two areas with the latter, namely the putamen and the insula.

Trivial reminders of money made a surprisingly large difference. For example, where the control group would offer to spend an average of 42 minutes helping someone with a task, those primed to think about money offered only 25 minutes. Similarly, when someone pretending to be another participant in the experiment asked for help, the money group spent only half as much time helping her. When asked to make a donation from their earnings, the money group gave just a little over half as much as the control group. Why does money makes us less willing to seek or give help, or even to sit close to others? Vohs and her colleagues suggest that as societies began to use money, the necessity of relying on family and friends diminished, and people were able to become more self-sufficient. "In this way," they conclude, "money enhanced individualism but diminished communal motivations, an effect that is still apparent in people's responses today."

We found voxels in the anterior Insula and adjacent frontal operculum to be involved in all three modalities of disgust, suggesting that simulation in the context of social perception and mental imagery of disgust share a common neural substrates. Using effective connectivity, this shared region however was found to be embedded in distinct functional circuits during the three modalities, suggesting why observing, imagining and experiencing an emotion feels so different.

Nice review of research on geographic differences in word-sorting and mental categories. Mentions the research of Richard Nisbett, The Geography of Thought: How Asians and Westerners Think Differently and Why.
