Some really interesting new research has revealed how people’s intelligence, rather than their personality traits, lead to success. This may be the wow! of the week. It also follows neatly on the previous piece of research.   What the researchers say: The team behind this study devised a series of games to find out which factors lead to cooperative behavior when people interact in social and workplace situations.[read more]

The more you rate people, the more positive you become about them.

Tasks often feel easier to perform as we gain experience with them, which can have unintended consequences when the task involves rating a series of people or items, according to findings published in the journal Psychological Science. The authors show that people tend to attribute the increasing ease of making ratings to the people or items themselves rather than to the ratings process, resulting in rating inflation over time.… [read more]

Do we have free will or is it a case of belief driving results?

For several decades, many researchers have argued that neurosgenetic studies prove human actions are driven by external stimuli—that the brain is reactive and free will is an illusion. But a new analysis of these studies shows that many may have contained methodological inconsistencies and conflicting results.… [read more]

Why economic growth does not necessarily contribute to human happiness.

This may well be the most important study published this year so far since it explains much of what is going wrong in our society. Economic growth in developed countries has a dual effect. On one hand, people’s living standards and consumer spending have, until recently, been rising but this does not necessarily make people happy and may in fact erode subjective wellbeing and lead to economic crises according to a number of studies (reported earlier in TR).… [read more]

Does ketamine really work as an antidepressant?

Antidepressant response within hours, or a blind alley? Experts weigh evidence on ketamine as a fast-acting treatment for depression in Harvard Review of Psychiatry.

Recent studies suggest that ketamine, a widely used anesthetic agent, could offer a wholly new approach to treating severe depression—producing an antidepressant response in hours rather than weeks.… [read more]

New method helps identify causal mechanisms in depression.

A new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging looks at the driving influence of brain regions in depression. What the researchers say:  The researchers note that people with major depressive disorder have alterations in the activity and connectivity of brain systems underlying reward and memory.… [read more]
