Relevant Variables

The effect of an adrenal demedullation on the acquisition of a signaled, one-way active avoidance response was examined in the rat. No significant differences in acquisition related to the adrenal demedullation were found on the four behavioral measures of response, avoidance and escape latency, and the number of avoidance responses. It was concluded that the catecholamines, epinephrine and norepinephrine, produced by the adrenal medulla are not necessary for the acquisition of a signaled, one-way, active avoidance response. The results indicate that response criteria and cue functioning in one-way acquisition are not relevant variables in resolving discrepancies in the adrenal demedullation literature. The findings suggest that unsignaled, two-way acquisition should be investigated for further clarification of the role of the adrenal medulla in avoidance behavior.
