Classifies subjects as cognitively simple" or cognitively complex" and notes that the latter are much nore successful at reconciling inconsistent information than are the former, whose impressions are formed by the information which makes the greatest impact. (RW)

Examines research which indicates that in the first days of life infants are able to elicit and respond to their mothers' behavior, however, it appears that the newborns exert more influence over the mothers' actions than the mothers exert over the infants' actions. (MH)

Reviews basic ideas presented in this special issue on the evolution of behaviorism. Topics addressed include stimulus and response; research with animals; applications to education and training; human motivation; theory through computer programs; experimental analysis of behavior; behaviorism moving into other disciplines; cognitive…

Discrepant effects of drugs on behavior maintained by temporal-discrimination procedures make conclusive statements about the neuropharmacological bases of timing difficult. The current experiment examined the possible contribution of a general, drug-induced disruption of stimulus control. Four pigeons responded on a three-component multiple…

Damage to the medial region of the thalamus, both in clinical cases (e.g., patients with infarcts or the Korsakoff's syndrome) and animal lesion models, is associated with variable amnesic deficits. Some studies suggest that many of these memory deficits rely on the presence of lateral thalamic lesions (LT) that include the intralaminar nuclei,…

Although it may be disconcerting to contemplate, true and false memories arise in the same way. Memories are attributions that we make about our mental experiences based on their subjective qualities, our prior knowledge and beliefs, our motives and goals, and the social context. This article describes an approach to studying the nature of these…

Two variables involved in attitude change provided the basis for this study, the cognitive complexity of the subject and the dimensions of stimulus materials. After a pretest, 165 interpersonal communication students were divided into two groups according to their cognitive complexity levels. The dimensions of the stimulus were presented on two…

The effects of observational purpose are thought to impact on such diverse processes as categorization, behavior perception, trait ascription, and memory. The role of observational purpose in the categorization of behavior was explored to determine whether differences between trait and goal concepts affect certain information-processing…
