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…

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…

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…
