Punishment contras during free-operant avoidance.

abstract：:A multiple schedule having both an appetitive and an avoidance component was maintained in two dogs to create a complex behavioral base line for observing the effects of chlorpromazine. Both soluble and "Spansule" chlorpromazine generated similar functions relating drug dose to measures of behavioral output. Although ...
