  • It's not solitaire: Brain activity differs when one plays against others
    Researchers have found a way to study how our brains assess the behavior -- and likely future actions -- of others during competitive social interactions. Their study is the first to use a computational approach to tease out differing patterns of brain activity during these interactions, the researchers report.

  • Why people can hold visual information in great detail in their working memory
    A new study may explain why people can hold visual information in great detail in their working memory.

  • Strategy shift with age can lead to navigational difficulties
    A researcher believes studying people's ability to find their way around may help explain why loss of mental capacity occurs with age.

  • Positive parenting during early childhood may prevent obesity
    Programs that support parents during their child?s early years hold promise for obesity prevention, according to a new study.

  • Hearing metaphors activates brain regions involved in sensory experience
    New brain imaging research reveals that a region of the brain important for sensing texture through touch, the parietal operculum, is also activated when someone listens to a sentence with a textural metaphor. The same region is not activated when a similar sentence expressing the meaning of the metaphor is heard.

  • The complex relationship between memory and silence
    People who suffer a traumatic experience often don't talk about it, and many forget it over time. But not talking about something doesn't always mean you'll forget it; if you try to force yourself not to think about white bears, soon you'll be imagining polar bears doing the polka. A group of psychological scientists explore the relationship between silence and memories.

  • Placebos and distraction: New study shows how to boost the power of pain relief, without drugs
    Placebos reduce pain by creating an expectation of relief. Distraction -- say, doing a puzzle -- relieves it by keeping the brain busy. But do they use the same brain processes? Neuromaging suggests they do. When applying a placebo, scientists see activity in the dorsolateral prefrontal cortex. That's the part of the brain that controls high-level cognitive functions like working memory and attention -- which is what you use to do that distracting puzzle.

  • To make a social robot, key is satisfying the human mind
    Understanding the human mind is the key to social robotics, and researchers describe what we can expect from this field in the future.

  • Schizophrenia: When hallucinatory voices suppress real ones, new electronic application may help
    When a patient afflicted with schizophrenia hears inner voices something is taking place inside the brain that prevents the individual from perceiving real voices. A simple electronic application may help the patient learn to shift focus.

  • How to tell apart the forgetful from those at risk of Alzheimer?s disease
    It can be difficult to distinguish between people with normal age-associated memory loss and those with amnestic mild cognitive impairment (aMCI). However people with aMCI are at a greater risk of developing Alzheimer?s disease (AD), and identification of these people would mean that they could begin treatment as early as possible. New research shows that specific questions, included as part of a questionnaire designed to help diagnose AD, are also able to discriminate between normal memory loss and aMCI.

  • Untangling the mysteries of Alzheimer's
    Researchers have found new evidence that confirms the significance of a protein that neuroscientists call tau to the development of Alzheimer's disease. While earlier studies have focused on tau's aggregation into twisted structures known as "neurofibrillary tangles," the new work emphasizes intermediary steps between single protein units and the much larger tangles ? small assemblages of two, three, four or more proteins, which the investigators believe are the most toxic entities in Alzheimer's.

  • Male and female behavior deconstructed
    Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how?

  • Men behaving nicely: Selfless acts by men increase when attractive women are nearby
    Men put on their best behavior when attractive ladies are close by. When the scenario is reversed however, the behavior of women remains the same.

  • Facebook is not such a good thing for those with low self-esteem, study finds
    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.

  • Here is what real commitment to your marriage means
    What does being committed to your marriage really mean? A psychology professors answer this question in a new study based on their analysis of 172 married couples over the first 11 years of marriage.

  • Alzheimer's disease may spread by 'jumping' from one brain region to another
    For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable brain regions at different times, or if it begins in one region and then spreads to neuroanatomically connected areas. A new study strongly supports the latter, demonstrating that abnormal tau protein, a key feature of the neurofibrillary tangles seen in the brains of those with Alzheimer's, propagates along linked brain circuits, "jumping" from neuron to neuron.

  • Brain capacity limits exponential online data growth
    Scientists have found that the capacity of the human brain to process and record information - and not economic constraints - may constitute the dominant limiting factor for the overall growth of globally stored information.

  • Just another pretty face: New insight into neural basis of prosopagnosia
    There is definitely more than meets the eye where faces are concerned. Researchers are investigating the process of facial recognition, seeking to understand the complexity of what is actually taking place in the brain when one person looks at another. The studies target people who display an inability to recognize faces, a condition long known as prosopagnosia. The research is aimed at trying to understand the neural basis of the condition while also make inferences about what is going wrong in terms of information processing -- where in the stages that our brains go through to recognize a face is the system breaking down. A new paper details the most recent experimental results.

  • Quarter of tweets not worth reading, Twitter users tell researchers
    Twitter users choose the microblogs they follow, but that doesn't mean they always like what they get. Researchers found that users say only a little more than a third of the tweets they receive are worthwhile. Other tweets are either so-so or, in one out of four cases, not worth reading at all.

  • In times of scandal, corporations are likely to use others' misconduct to justify their behavior
    Among corporations involved in the 2006 stock-option backdating scandal, those implicated earlier were more likely to dismiss their top executives than those that surfaced later on, according to new research.
