title: Use of discrimination behavior for the evaluation of toxicants.
abstract: This study involved the application of discrimination behavior for the study of effects of environmental contaminants on the behavior of laboratory animals. Polybrominated biphenyl (PBB) was evaluated for effects on the acquisition and performance of a simple auditory discrimination by rats. Methyl ethyl ketone (MEK), methyl isobutyl ketone (MIBK) and carbon monoxide (CO) were evaluated for effects on a delayed match-to-sample discrimination task in the juvenile baboon. All of the contaminants slowed response times and increased extra responses. These findings suggest that discrimination behavior may be of value for the evaluation of environmental contaminants for effects on the central nervous system.
