In theory, the social networking website Facebook could be great for people with low self-esteem. Sharing is important for improving friendships. But in practice, people with low self-esteem seem to behave counterproductively, bombarding their friends with negative tidbits about their lives and making themselves less likeable, according to a new study which will be published in Psychological Science, a journal of the Association for Psychological Science.
“We had this idea that Facebook could be a really fantastic place for people to strengthen their relationships,” says Amanda Forest, a graduate student at the University of Waterloo. She cowrote the new study with her advisor, Joanne Wood. The two are generally interested in self-esteem, and how self-esteem affects the kinds of emotions people express. People with low self-esteem are often uncomfortable sharing face-to-face, but Facebook makes it possible to share remotely.
In one study, Forest and Wood asked students how they feel about Facebook. People with low self-esteem were more likely to think that Facebook provided an opportunity to connect with other people, and to perceive it as a safe place that reduces the risk of awkward social situations.

A woman’s memory of an experience is less likely to be accurate than a man’s if it was unpleasant and emotionally provocative, according to research undertaken by University of Montreal researchers at Louis-H Lafontaine Hospital. “Very few studies have looked at how ‘valence’ and ‘arousal’ affect memories independently of each other, that is to say, how attractive or repulsive we find an experience and how emotionally provocative it is,” said corresponding author Dr. Marc Lavoie, of the university’s Department of Psychiatry and the hospital’s Fernand-Seguin Research Center. “Our test relied on photos – we found firstly that highly arousing pictures blur women’s capacity to determine whether they’ve seen it before, and secondly that women have a clearer memory of attractive experiences than men. Arousal has an enhancing effect on the memory of men however, as does ‘low valence’ or unpleasantness.” [continue reading…]

Researchers from Mount Sinai School of Medicine have discovered that decaffeinated coffee may improve brain energy metabolism associated with type 2 diabetes. This brain dysfunction is a known risk factor for dementia and other neurodegenerative disorders like Alzheimer’s disease. The research is published online inNutritional Neuroscience.
A research group led by Giulio Maria Pasinetti, MD, PhD, Professor of Neurology, and Psychiatry, at Mount Sinai School of Medicine, explored whether dietary supplementation with a standardized decaffeinated coffee preparation prior to diabetes onset might improve insulin resistance and glucose utilization in mice with diet-induced type 2 diabetes. The researchers administered the supplement for five months, and evaluated the brain’s genetic response in the mice. They found that the brain was able to more effectively metabolize glucose and use it for cellular energy in the brain. Glucose utilization in the brain is reduced in people with type 2 diabetes, which can often result in neurocognitive problems. [continue reading…]

Measuring how a baby’s brain reacts to shifts in eye contact might help predict the development of autism symptoms from as young as six months, a new study has found.
La Trobe University psychologist Dr Kristelle Hudry, from the Olga Tennison Autism Research Centre on the Melbourne campus, is one of the key researchers in the international study which was released today.
She says the results of the study ‘Infant neural sensitivity to dynamic eye gaze is associated with later emerging autism’ have been published in the January 26th issue of the journal Current Biology.
‘These results are important because early diagnosis can secure the best possible outcome for individuals with autism spectrum disorders (ASD), through early access to intervention. They also open up new avenues for scientists to carry out further research, to help us better understand the condition.’
