A complete quantitative account of P. Wason's (1966) abstract selection task is proposed. The account takes the form of a mathematical model. It is assumed that some response patterns are caused by inferential reasoning, whereas other responses reflect cognitive processes that affect each card selection separately and independently of other card…

A comparison was made between two procedures for testing whether an alpha-numeric character, which was pattern masked to prevent awareness, could access higher-order information concerning its category. (Author)

Examined the effect of attention on infants' responses to briefly exposed visual stimuli. Found that the duration of stimulus exposure in the familiarization phase was positively correlated with the preference for the novel stimulus in the paired-comparison procedure, and processing of briefly presented visual stimuli differed depending on the…

First-, third-, and fifth-grade children played a board game with another same-age, same-sex child. Results demonstrated why young children are as likely to respond competitively as cooperatively under shared-reward conditions. (BJD)

A technique is introduced to study the flow of information through processing stages in choice reaction time tasks. It was designed to determine whether response preparation can begin before stimulus identification is complete ("continuous" models) or if a stimulus must be fully identified prior to any response activation…

Differences between learning disabled and nonlearning disabled children's paired-associate learning can be eliminated by using instructional modifications. Procedures that reduce the "overloading" of the learning disabled students' cognitive processes have positive effects on associative learning. (CJ)

Examined the effects of perceived control and close alternative outcomes on counterfactual generation (thoughts of what could have been). Subjects played a "wheel of fortune" game in which they controlled one of two wheels. Results supported the idea that people generate counterfactuals about events over which they have perceived…

Examined impact of outcome controllability on counterfactual thoughts (thoughts of what could have been). Two studies showed that outcome controllability affected counterfactual direction: thoughts on how things could have been better were more frequent following controllable outcomes, and thoughts on how things could have been worse followed…

Investigated whether actors and observers differ in their beliefs about what features of an individual best reflect his/her "authentic self." Results indicate that actors' views differed significantly from observers'. Friend raters believed that their friends' dispositional traits were better indicators than what their friends actually did,…

Reports on students' study and drawing of five electronic circuit diagrams. Concludes that the success of the students depended upon the amount of detail in the instructional diagrams. (RT)
