New research shows babies have a handle on the meaning of different dog barks - despite little or no previous exposure to dogs. Infants just 6 months old can match the sounds of an angry snarl and a friendly yap to photos of dogs displaying threatening and welcoming body language. The new findings come on the heels of a study from the same Brigham Young University lab showing that infants can detect mood swings in Beethoven's music. Though the mix of dogs and babies sounds silly, experiments of this kind help us understand how babies learn so rapidly. Long before they master speech, babies recognize and respond to the tone of what's going on around them.
With 1.4M Grant From NIH, LSUHSC's Nichols To Use LSD And Fruit Flies To Identify Novel Genes For Psychosis Schizophrenia
Charles Nichols, PhD, Assistant Professor of Pharmacology at LSU Health Sciences Center New Orleans, has been awarded a grant in the amount of $1.4 million over four years by the National Institutes of Health's National Institute of Mental Health to find and characterize novel genes involved in psychosis and schizophrenia, using novel research methods. Dr. Nichols' approach is innovative, combining discovery studies with functional and behavioral studies in two different models to determine how mental disorders like psychosis and schizophrenia develop. By studying both a new rodent model of psychosis that he is co-developing, which involves treating rats with the powerful hallucinogenic drug lysergic acid diethylamid (LSD), and the fruit fly, Drosophila melanogaster, analysis of gene function relative to whole animal behavior can be accomplished more rapidly than with traditional rodent models alone.
Young men who stay at home with their parents are more violent than those who live independently, according to new research at Queen Mary, University of London. The new study* indicates that men still living at home in their early twenties have fewer responsibilities and more disposable income to spend on alcohol. This group makes up only four percent of the UK's male population but they are responsible for 16 per cent of all violent injuries in the last five years. Delaying social independence and remaining in the parental home have become more common over the past 40 years in both the UK and the USA. Professor Jeremy Coid and Dr Ming Yang surveyed over 8000 men and women.
Say a deadly campus shooting occurs. It might seem sensible to offer everyone on campus psychological support to prevent psychological repercussions, including posttraumatic stress disorder (PTSD). However, a new review from Wales and Australia suggests the opposite: Researchers found no evidence to support offering interventions to everyone involved in a traumatic event. In fact, they found that some forms of blanket intervention might foster worse outcomes than no intervention whatsoever. "Some experts argue everyone should be offered help. Others argue that only those considered at particular risk of developing a psychological disorder should be treated.
For over a century neurologists and psychologists have investigated how the human brain processes and controls the imitation of gestures, and looked for differences depending on whether the gestures were meaningful, such as grabbing an object, or meaningless, on the goal of the action, and on the body part used. Recent neuropsychological findings both in healthy subjects and brain-damaged patients have suggested various cognitive explanations, reviewed here. The most influential are the so-called "dual-route models": they suggest a default or direct route, and a more complex one associated with meaning, and they are supported by accounts that relate the imitation deficit to putative degraded body representations.
Experts from the Institute of Psychiatry will tell attendees of a unique conference on the 25th July in Reading that health professionals often fail to correctly identify when someone suffers from Obsessive-Compulsive Disorder (OCD). As a consequence, the burden of this very disabling and distressing condition tends to fall on family members. Key OCD experts will explore the extent of this problem and ways it can be better dealt with at a unique conference, the first event of its kind, an OCD conference specifically aimed at the family, friends and carers of people with OCD. The conference will also hear from Dr Fiona Challacombe who will report that Obessional problems during pregnancy and postnatal often go undetected.
