Tics are rapid, repetitive, stereotyped movements or vocalizations that arise from neurobiological dysfunction and are influenced by environmental factors. Although persons with tic disorders often experience aversive social reactions in response to tics, little is known about the behavioral effects of such consequences. Along several dimensions,…

Monkeys exposed to stress inoculation protocols early in life subsequently exhibit diminished neurobiological responses to moderate psychological stressors and enhanced cognitive control of behavior during juvenile development compared to non-inoculated monkeys. The present experiments extended these findings and revealed that stress inoculated…

Stress is a biologically significant social-environmental factor that plays a pervasive role in influencing human and animal behaviors. While stress effects on various types of memory are well characterized, its effects on other cognitive functions are relatively unknown. Here, we investigated the effects of acute, uncontrollable stress on…

Indicates that a feeling of control over the environment affects the subject's response to aversive stimuli. This finding helps to reconcile those of other experimenters in the area. (RW)

The amount of anxiety suggested the need for clinical intervention to reduce procedure-related distress in children with cancer. Younger children exhibited consistently higher levels of distress than older children and displayed a greater variety of anxious responses over a longer time span. (Author/BEF)

These studies focused on sex differences and were designed to test the hypothesis that girls were more likely to be immobilized by a fear stimulus than boys. (Authors/CB)

Reports results of a study which tested the following model to predict group panic behavior: that panic reactions are characterized by the exercise of inappropriate leadership behaviors in situations of high stress. (PD)
