Recent studies of deductive reasoning are reviewed with respect to three questions: Do people reason logically? Is reasoning introspectible? Is reasoning sequential? It is argued that the evidence of reasoning experiments suggests a negative answer to all three questions, indicating that these experiments don't study "reasoning" in its everyday…

Two experiments explored how memory for new information is affected by awareness of parallels to pre-experimental knowledge. Results suggest that the benefit of prior knowledge derives from the more elaborate encodings that analogy promotes. (Author/AM)

A series of three experiments investigated repetition effects on recall with homographic responses. It was concluded that the repetition increment was mediated solely by commonality of surface features and that semantic features played no role. (Author/AM)

Summarizes current research regarding the influence of cognition (things people think and feel) in the understanding of human social behavior. Discussed are experiments in attribution, social perception, self-concept, and attitude change which contribute to the author's point that the cognitive theme is becoming a unifying phenomenon in social…

Determined whether category norms collected from college students are appropriate for research with older adults. Concluded that for most of the categories studied here, it is appropriate to use the Battig and Montague norms when choosing stimuli for experiments with middle-aged and elderly adults. (Author)

Presents a series of four experiements designed to test the view that the process where a spoken suffix impairs retention of a sequence's last item has a different basis from that producing impairment of the retention of an earlier item. (AM)

Examines the reasons for differences in conclusions about the way conditional sentences are comprehended. (AM)

Reports on an investigation of the role of letter and order information in lexical access, using an interference paradigm in a lexical decision task. (Author/AM)

This study investigated the relationship between giftedness and conservation of weight based on Piaget's theory of intelligence. A total of 56 gifted and 72 nongifted children (ages 114-150 months) were tested on a series of tasks designed to measure conservation of weight. (MS)

Three experiments, employing conditioned suppression in rats, examined the extent to which pretraining on one element of a compound stimulus blocked conditioning to the other element when some feature of the reinforcer was changed on compound trials. (Editor)

The research reported here was directed at evaluating whether or not the effectiveness of a Pavlovian unconditioned stimulus (US) in promoting associative learning is reduced if the US is shortly preceded by another occurrence of the same US. (Author)

Stimulus analyzer theory as proposed by Sutherland and Mackintosh (1971) makes the unique prediction that the first-experienced reinforcement schedule will influence resistance to extinction more than subsequent schedules. Results presently reported of runaway acquisition and extinction indicate the opposite: C-P consistently produce substantially…

This study provides experimental evidence that instructional set can influence access to altered states of consciousness. Fifteen male subjects were randomly assigned to three groups, each of which received the same autogenic biofeedback training in hand temperature control, but each group received a different attitudinal set. (Editor)

Recent data indicate that the form of the conditioned response (CR) may often be substantially influenced by the characteristics of the conditioned stimulus (CS) as well as by those of the unconditioned stimulus (US). Here five experiments examine the influence of CS characteristics on the form of the Pavlovian CR anticipatory to a food US in…

Sought to elucidate the nature of odor memory by applying paradigms from verbal learning and semantic memory and to investigate two processes affecting paired-associate performance. (Author/RK)
