Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

Examined relationships between employment and crime in 61 male misdemeanants. For many, low-level employment and crime were not mutually exclusive, although most respondents were not employed at the time of the arrest that led to their current incarceration. Combinations of employment and crime were more complex than anticipated. (JAC)

Younger (N=48) and older (N=48) males participated in a vocabulary task involving varying degrees of risk under neutral, supportive, and challenging instructions. Results indicated older adults were more cautious, selected tasks with higher probabilities of success, and were less likely to raise their level of aspiration following success. (Author)

Younger men are both less engaged from the world and more efficient processors of information than older (especially less educated) ones. (Authors)

Data on aggressive…
