Instrumental-avoidance conditioning and classical conditioning as utilized in electrodermal audiometry were compared within a group of 18 normal hearing subjects, a second group of 18 subjects with sensori-neural hearing losses and a third group of 18 subjects suspected of having nonorganic hearing losses. Statistically significant differences and consistent trends suggest that instrumental-avoidance conditioning provided stronger conditioning, greater resistance to adaptation, and better discrimination learning than did classical conditioning within all three groups of subjects. Between-groups comparisons suggest that nonvolunteer subjects are more responsive than volunteer subjects during EDA when electric shock is utilized as the unconditioned stimulus.

Cholinergic Mechanism

Administration of a single dose (200 mg/kg, p.o.) of carbaryl to rats produced a significant rise in adrenal and plasma corticosterone levels and an increase of tyrosine α-ketoglutarate transaminase activity in the liver cytosot. Synaptosomal acetylcholinesterase activity of the hypothalamic and the striatal regions of rat brain was decreased by carbaryl treatment under similar conditions. Pretreatment (0.5 h) with atropine sulphate (10 mg/kg, i.p.) failed to counteract the carbaryl-induced elevation of adrenal and plasma corticosterone levels and hence the liver tyrosine α-ketoglutarate transaminase activity. Present results suggest that the carbaryl-induced rise in the corticosterone level in the adrenal gland and plasma is not due to a cholinergic mechanism.
