A new study says so-called "heavy multitaskers" have trouble tuning out distractions and switching tasks compared with those who multitask less. And there's evidence that multitasking may weaken cognitive ability. Stanford University professor Clifford Nass explains the work.
An overview of neuroethics and neurolaw that covers a lot of ground, from Phineas Gage to comas. Ways that the brain controls behaviour, issues of responsibility and accountability in the legal system, decision making, recidivism and rehabilitation, predicting violence, the hype and reality of fMRI lie detectors and the implicit association test (IAT), and more.

What makes people behave honestly when confronted with opportunities for dishonest gain? Research on the interplay between controlled and automatic processes in decision making suggests 2 hypotheses: According to the “Will” hypothesis, honesty results from the active resistance of temptation, comparable to the controlled cognitive processes that enable the delay of reward. According to the “Grace” hypothesis, honesty results from the absence of temptation, consistent with research emphasizing the determination of behavior by the presence or absence of automatic processes.

Facial expressions, Charles Darwin argued in The Expression of the Emotions in Man and Animals, are a universal window into emotion. But new research challenges that notion, showing that east Asian people struggle to recognise facial expressions that western Caucasians attribute to fear and disgust. By focusing on eyes and brows, Asians miss subtle cues conveyed via the mouth. (13 August 2009 - New Scientist)

A US survey in 2004 had found that up to 25% of people claimed that they had no real intimates. Yet by 2007 there was networking technology where people would ask: ‘Can I be your friend?’ What is it all about? Why is it so important?
