Abstract

This study evaluates endorphins as a mediator of learned helplessness. Thirty-two male rats (i.e. Evans hooded) were randomly assigned to one of four groups: an escape group, a helpless group, a helpless group treated with naloxone, and a helpless group treated with a placebo. The helpless animals injected with naloxone reacted to shock statistically similar to naive animals. This group (i.e. the helpless plus naloxone group), while similar to the escape group, remained similar to the helpless and helpless + placebo groups. Consequently it appears that endorphins are a factor in the helpless condition. However, the extent is yet to be determined.
