Abstract
Immature rats were trained in two-way shuttle avoidance and tested for generalization in extinction along the frequency and intensity dimensions of the CS. While symmetrical decrements in response strength around the original CS value were found when frequency was varied alone, marked dynamism effects emerged during intensity generalization. Concurrent variation of both dimensions resulted in increased stimulus control by frequency with higher intensity levels. Previous findings of aversively motivated stimulus generalization in young and adult rats were considered.
