title: Learned Helplessness in the Rat: An Elusive Phenomenon.
abstract: A series of three experiments, using 48 albino rats as Ss, manipulated the intensity and duration of inescapable treatment shock. Subsequent testing on the acquisition of an FR-3 lever-press response to terminate test shock showed no interference effects whether test shock was the same, less intense, or more intense than treatment shock.
