Perceptual expertise is typically domain-specific and rarely generalises beyond an expert's domain of experience. Forensic feature-comparison examiners outperform the norm in domain-specific visual comparison, but emerging research suggests that they show advantages on other similar tasks outside their domain of expertise. For example, fingerprint…

In Experiment 1, "more" and "less" relations were trained for arbitrary Stimuli A1 and A2 with 3 children with autism. The following conditional discriminations were then trained: A1-B1, A2-B2, B1-C1, B2-C2. In subsequent tests, participants showed derived more-less mands (mand with C1 for more and mand with C2 for less). A training procedure…

The initial learning and subsequent transfer of an oddity principle by 50 children between 4 and 5 years of age were studied. The initial standard oddity problem was learned quickly by most of the children. A high level of performance was maintained on both transfer sets. (MS)

AN OVERVIEW OF THE RESEARCH ON VISUAL DISCRIMINATION SHOWS A TREND FROM THE WHOLE-WORD VIEW TO A COMBINATION OF LETTER-DISCRIMINATION AND THE WHOLE-WORD METHOD. TEN STUDIES CITED IN THIS ARTICLE ATTEMPTED TO ANSWER THE FOLLOWING QUESTIONS--(1) WOULD NONVERBAL STIMULI FACILITATE READING PERFORMANCE, (2) DO CHILDREN FOCUS ON THE SHAPE OF THE WORD OR…

Findings were: it did not matter whether the seriation involved the hues used in subsequent tasks or other hues; the presence or absence of reinforcement during perceptual pretraining did not affect pretraining, training, or transposition behavior; and seriation pretraining produced increased transposition in the intermediate-hue problem.…

Verbal self-instruction was employed in training impulsive first-grade children to perform visual discrimination matching tasks. Posttests, following the four training conditions, showed that while strategy training increased latency, self verbalization both increased latency and reduced errors. (Author/DEP)

Children often perseverate, repeating prior behaviors when inappropriate. This work tested the roles of verbal labels and stimulus novelty in such perseveration. Three-year-old children sorted cards by one rule and were then instructed to switch to a second rule. In a basic condition, cards had familiar shapes and colors and both rules were stated…

Forty kindergarten children were randomly assigned to four conditions to investigate the influence of criterion level on the discrimination of highly confusable letters in beginning reading. Half the subjects were exposed to simultaneous, and half to successive discriminations. The groups were equally divided as to criterion level, i.e., four vs.…

Children were individually administered the Matching Familiar Figures (MFF) Test and the Haptic Matching Task. Impulsives received either reflective scanning strategy training or control procedures and were retested. Visual training decreased errors only on the MFF and increased latency on both tasks. Haptic training decreased errors and increased…

Procedures for programing computers to deal with handicapped students, problems in selective attention, visual discrimination, reaction time differences, short term memory, transfer and generalization, recognition of mistakes, and social skills are discussed. (CL)

The research experiments on relational learning in young children contained in this report were guided by two major goals: (1) to examine the extent of conceptual transfer in preschool children, and (2) to explore the relation of both "acquisition" and "transfer" to chronological development. The performance of preschool…

TO STUDY WHICH OF SEVERAL CONDITIONS PROMOTES EFFICIENT CONCEPT LEARNING, AN EXPERIMENT INVOLVING 2 CONDITIONS, METHOD OF PRESENTATION OF STIMULI AND RATIO OF POSITIVE TO NEGATIVE STIMULI, WAS ADMINISTERED TO 80 SECOND-GRADE CHILDREN. THE CHILDREN WERE DIVIDED INTO 8 TREATMENT GROUPS. THESE 8 GROUPS WERE FORMED BY VARYING THE 2 METHODS OF…

Two experiments examined pigeons' generalization to intermediate forms following training of concept discriminations. In Experiment 1, the training stimuli were sets of images of dogs and cats, and the transfer stimuli were head/body chimeras, which humans tend to categorize more readily in terms of the head part rather than the body part. In…

Twenty-seven kindergarten subjects were trained on two different double classification matrix tasks to determine whether they were hierarchically related. Prior behavioral analyses had shown one task to be simpler than the other. It was assumed that, in hierarchical transfer relationships, one order of task acquisition is more favorable than…
