Every day we have to make decisions that involve evaluating or choosing between options, often without much information to go on. So how we do it? How do we prevent analysis paralysis? Psychological theory suggests that we often rely on the recognition heuristic, choosing the option that we recognize over the one we do not. So, as psychological scientist Christian Frings points out, if we have to predict whether Roger Federer or Michael Berrer will win a tennis match, we will probably stick with Federer because he is a well-known name.

The assumption that we human beings can control and intentionally forget unwanted memories has been controversial ever since Freud asserted it at the beginning of the 20th century. Now, psychology researcher Gerd Thomas Waldhauser has shown in neuroimaging studies that Freud was correct in his assumptions: in the same way as we can control our motor impulses (we can, for example, rapidly instruct the brain not to catch a cactus which is falling from a table), we can control our memory.
In the late 1990s, Jane Anderson was working as a landscape architect. That meant she did not work much in the winter, and she struggled with seasonal affective disorder in the dreary Minnesota winter months. She decided to try meditation and noticed a change within a month. Her experience inspired a new study which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, which finds changes in brain activity after only five weeks of meditation training.
Researchers are now discovering that children as young as 3 years of age can meet the clinical criteria for major depressive disorder (MDD). What is more, they demonstrate patterns of brain activation very similar to those seen in adults diagnosed with the disorder. Take for instance, Callie. From a distance, she appears to be a normal if quiet 5-year-old girl. But when faced with a toy that blows large soap bubbles — an activity that makes the vast majority of kindergarteners squeal and leap with delight — she is uninterested in popping the bubbles or taking a turn with the gun herself. When offered dolls or other toys, she is equally unmoved.
The International Society For Neurofeedback And Research (ISNR) will hold its 2011 annual conference in Phoenix, Arizona. ISNR conferences are the premier international meetings for healthcare professionals, students, teachers, and researchers who are interested in psychophysiology, particularly peripheral biofeedback, neurofeedback, and quantitative EEG (QEEG).
There is a significant need for objective tests that could improve clinical prediction of future psychosis. In this new study, the researchers followed a group of people clinically at high risk for developing psychosis. They found that the individuals who went on to develop schizophrenia had smaller MMN than the subgroup who did not. This finding suggests that MMN might be useful in predicting the later development of schizophrenia.
Neuroscientists of the Charité – Universitätsmedizin Berlin have now been able for the first time to document deliberate control of touch sensations in human working memory. It has been shown that the human brain can remember several touch sensations at the same time and consciously retrieve the touch if concentration is focused on these touches. This work is now published in the current issue of the prestigious journal PNAS.
Have you ever lost your keys or stuck the milk in the cupboard and the cereal in the refrigerator and wondered what happened? Researchers at the University of Wisconsin-Madison have a new explanation. They found that some nerve cells in a sleep-deprived yet awake brain can briefly go “off line,” into a sleep-like state, while the rest of the brain appears awake.
