New Research From Psychological Science
Magnocellular and Parvocellular Contributions to Conscious and Nonconscious Vision Evelina Tapia and Bruno G. Breitmeyer When it comes to consciousness and vision, the magnocellular (M) channel in the dorsal cortical pathway has been associated with nonconscious visual processing, and the parvocellular (P) channel in the ventral cortical pathway has been connected to conscious visual processing. In this study, researchers used contrast-dependent primes to determine whether the priming effects were characteristic of M- or P-channel responses. They found that M channels have a significant role in conscious vision and propose a new mechanism for how the channels function.

Fear, anger prompt us to share stories, messages
Yahoo News: Certain emotions like fear, anger or plain amusement prompt us to share articles, news and stories with our friends and acquaintances. According to a University of Pennsylvania research, these emotions are characterized by high arousal and action, unlike sadness or contentment, emotions linked with low arousal or inaction. 'If something makes you angry as opposed to sad, for example, you're more likely to share it with your family and friends because you're fired up,' says Jonah Berger, study co-author and assistant professor of marketing at the university.

Fertile women are more prejudiced against strange men, U.S. study says
The Vancouver Sun: Women are more prejudiced toward male strangers when they are fertile, says a new U.S. study, which suggests bias is partly ingrained in human DNA. Researchers at Michigan State University asked 252 female university students, both Caucasian and black, to look at photos of men's faces, also both Caucasian and black. The women then had to link each face with either a physical adjective, such as muscular, or a mental one, such as brainy. The women, who were not pregnant nor on hormonal birth control, also recorded their menstrual cycles. Read more: The Vancouver Sun

Psychologists, Science Journalists Duel Over Cigarette Warnings
The Wall Street Journal: What does the psychological research say about the effectiveness of putting graphic images on cigarette packs? I haven’t had a chance to sort through the original research articles myself, but science journalists are presenting some seriously variant conclusions. According to ScienceInsider,"Scary New Cigarette Labels Not Based on Psychology." The author of the piece quotes the behavioral psychologist Carol Tavris: “Has anyone been to the movies lately? [HBO's] ‘Game of Thrones,’ where people’s heads are cut off in front of you? I think people’s tolerance for the ugly and the violent is quite high.” Read more: The Wall Street Journal
