Twenty-six male rhesus monkeys were sacrificed and organ pathology was completed. The following measures were taken body weight, brain weight, thymus weight, adrenal weight, brainbody ratio, thymusbody ratio, adrenalbody ratio and gross and microscopic organ pathology. Differences between these measures based upon 1 early rearing experience and 2 shock-induced stress exposure were not significant. Intercorrelations between these measures were also computed a number of them were found to be significant. Performance on a shock-escape match-to-sample task was found to correlate significantly with brain weight and brainbody ratio. Findings of this study do not agree with results of similar studies conducted on rats. Author
