GALVANIC SKIN RESPONSE CONDITIONING DEFICIT IN AMYGDALECTOMIZED MONKEYS

Amygdalectomized monkeys have depressed galvanic skin responses during tests of the orienting reaction to repeated presentation of simple tones. An effort to condition the galvanic skin response (GSR) with electric stimulation of skin was instituted. No evidence of conditioning of a weak conditional stimulus (light off) was obtained from the amygdalectomized monkeys in a differential classical situation, despite normal GSR to skin stimulation. Normal monkeys were found conditionable. © 1968.
