Three experimentally naive abnormal children were exposed to a terminal operant contingency, i.e., reinforcement was delivered only if the children pressed a panel during intervals when it was lighted. Despite the absence of both successive approximation and manual shaping, it was found that each child began to respond discriminatively within a small number(More)
Two experiments are reported that attempted to replicate conceptually Schachter's theory of the determinants of emotion and to test the feasibility of extending the theory to attitudes and behavior that may be mediated by the emotion of fear. A total of 279 cigarette smokers were administered either epinephrine or a placebo and then exposed to situational(More)
Despite the research interest in modifying smoking behavior, therapeutic treatments that can produce long-term cessation have not been demonstrated rigorously. A follow-up study of two attitude change experiments (N = 173) examined the effects of a fear appeal, that is, increasing smokers' awareness and appreciation of the highly noxious consequences of(More)
Stimulus properties such as similarity-dissimilarity and novelty-familiarity are inherently relational and are embedded in ubiquitous stimulus contexts. Children with mental retardation and young children without mental retardation are particularly prone to failure on relational tasks such as oddity and match-to-sample (Greenfield, 1985; Soraci et al., in(More)
Large individual differences exist among psychotic and retarded children, and a procedure that would enable classification of discrimination learning ability would be of value. A procedure designed to assess the discrimination learning thresholds of low-functioning children is described. A performance index (PI) that reflects accuracy of discriminative(More)
Administered the Stanford-Binet and/or its downward extension the Cattell Infant Intelligence Scale to 22 children in a school for severely behaviorally disordered boys and girls. Assessments also were made with the Vineland Social Maturity Scale and with a scale of language development. A subgroup of 17 children were assessed with Rimland's E-2 Scale,(More)
