Chain of violence: Study shows impact on Palestinian and Israeli children Posted: 21 Aug 2012 06:43 AM PDT Children exposed to ethnic and political violence in the Middle East are more aggressive than other children, and the younger the child, the stronger the effect.

Sacrificing sleep to study can lead to academic problems Posted: 21 Aug 2012 06:43 AM PDT Regardless of how much a high school student generally studies each day, if that student sacrifices sleep in order to study more than usual, he or she is more likely to have academic problems the following day. These are the findings from a longitudinal study of 535 9th, 10th, and 12th graders who kept detailed diaries for 14 days on how long they studied and slept, and whether or not they experienced academic problems.

For poorer children, living in a high-cost area hurts development Posted: 21 Aug 2012 06:42 AM PDT Researchers have found that young children in lower-income families who live in high-cost areas don't do as well academically as their counterparts in low-cost areas. The study used data from a nationally representative sample of more than 17,500 children at more than 2,000 schools who started kindergarten in 1998. Differences for lower-income families according to cost of living in the area of residence held even when taking into account a comprehensive set of demographic variables.

Infants' avoidance of drop-off reflects specific motor ability, not fear Posted: 21 Aug 2012 06:42 AM PDT Researchers have long studied infants' perceptions of safe and risky ground by observing their willingness to cross a visual cliff, a large drop-off covered with a solid glass surface. Now a new study has found that although infants learn to avoid the drop-off while crawling, this knowledge doesn't transfer to walking. This suggests that what infants learn is to perceive the limits of their ability to crawl or walk, not a generalized fear of heights.

Computer program recognizes any language Posted: 21 Aug 2012 06:41 AM PDT New technology that allows computers to recognize any language without pre-learning stands to revolutionize automatic speech recognition.

Patient suffers severe amnesia but musical memory remains intact Posted: 21 Aug 2012 06:40 AM PDT Scientists have examined a professional cellist who suffered from encephalitis caused by a herpes virus. As a result of the inflammation, the patient developed serious disturbances in memory. Both his memory for the past (retrograde amnesia), as well as the acquisition of new information (anterograde amnesia) were affected. Whereas the patient was unable to recount any events from his private or professional life, or remember any of his friends or relatives, he retained a completely intact musical memory.
