Compared the performance of children with and without autism in object-based positive and negative priming tasks within a visual search procedure. Found object-based positive and negative priming effects in both groups, with no group differences in the magnitude of the effects. Compared to typically developing children, children with autism were…

Two experiments compared 6-month-olds' numerosity discrimination performance on both large numbers and small numbers with both total filled area and total contour length controlled. Results showed that infants succeeded in discriminating 4 from 8 elements, but failed to discriminate 2 from 4 elements, providing evidence for the existence of two…

Results of two experiments show that only postinformative feedback intervals to be significant sources of variation; mean trends appeared to indicate that extended preresponse intervals interfere with performance, if anything. (Authors/MB)

Describes an empirical investigation of the differences in learning strategies or approaches of 30 university students. The results indicate that the differences in approach may be found in the kind of information focused on and learned rather than how much people learn in a quantitative sense. Thirty-six references are listed. (CHC)

A study involving 110 fifth- and sixth-graders (51 male and 59 female), classified as low or high in effort orientation, assessed the effects of task- versus performance-oriented instructions on a computer-assisted test programed to ensure that all examinees failed to solve all problems. Problem-solving strategy analyses were preformed. (TJH)

Compared the processing of rapid auditory stimuli on two-tone auditory discrimination tasks by 7- to 11-year-olds with learning impairments (LI) and those without learning impairments (non-LI). Found that LI children committed more errors, but the effects of timing were comparable. Obtained same results with a sample of good and poor readers. Task…

TWO STRATEGIES FOR TEACHING MULTIPLE-DISCRIMINATION TASKS WERE REPORTED. THE "MULTIPLE CONCEPT" PRESENTS SIMPLE DESCRIPTIONS OF SEVERAL RELATED CONCEPTS AT THE BEGINNING OF INSTRUCTION. INCREASINGLY COMPLEX MATERIAL PERTAINING TO THESE CONCEPTS IS THEN GRADUALLY INTRODUCED. THE "SINGLE CONCEPT" PRESENTS ONE CONCEPT AT A TIME,…
