Study Suggests Light-to-Moderate Drinking During Pregnancy Is Ok

A series of research articles in the British Journal of Obstetrics and Gynecology suggest that light-to-moderate drinking during pregnancy (up to 8 drinks per week) does not affect IQ [1], intelligence, attention, and executive function [2], selective and sustained attention [3], or general intelligence [4] in 5-year-old children.

NIH-funded Study Finds Dyslexia Not Tied to IQ

Regardless of high or low overall scores on an IQ test, children with dyslexia show similar patterns of brain activity, according to researchers supported by the National Institutes of Health. The results call into question the discrepancy model — the practice of classifying a child as dyslexic on the basis of a lag between reading ability and overall IQ scores.

Encephalon #58 – Decision Making

Welcome to the 58th edition of Encephalon, where we highlight some of the best neuroscience and psychology blog posts from around the blogosphere. This edition includes 20 articles on a variety of interesting topics, including intelligence, belief, neurodegeneration, multi-tasking, memory, grief and consciousness.

There’s a revolution occurring on the Web: those “authoritative” articles written on traditional, static websites are being replaced with blogs, wikis and online social networks. In the sphere of health, medicine and information technology, this “real-time Web” consists of many who are professionals in the field; their posts are listed below.
In the digital age, these are the characteristics of new media: recent, relevant, reachable and reliable.

This edition of Encephalon coincides with the historic 44th U.S. Presidential election. As with every election, voters had to decide which candidate for whom to cast their ballot. Although a recent brain-imaging study found that voting decisions are more associated with the brain’s response to negative aspects of a politician’s appearance than to positive ones [1], many other sources of information come into play when we make important and complex decisions. Indeed, studies have shown that decision making is largely an unconscious process [2], in which a set of attributes, including needs, preferences, values and emotions, shape our response to sensory input.

Will there be engaging and thought-provoking articles below? Will each of us learn something new as we read through the posts? Will this edition of Encephalon be successful?

Let’s move through each of the attributes and shape our response to these questions.
