The mathematical representation of E. Brunswik's (1952) lens model has been used extensively to study human judgment and provides a unique opportunity to conduct a meta-analysis of studies that covers roughly 5 decades. Specifically, the authors analyzed statistics of the "lens model equation" (L. R. Tucker, 1964) associated with 249 different…

Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue…

Sixty-four adults participated in a study examining the accuracy of metacognitive judgments during 28 hr of sleep deprivation (SD) and continuous cognitive work. Three tasks were studied (perceptual comparison, general knowledge, and mental addition), collectively spanning a range of cognitive abilities and levels of susceptibility to SD.…

Assesses children's comprehension of "because" and "so" on enactment and sentence completion tasks. Results provide evidence against a componential model for the acquisition of causal connectives. Supported is the position that understanding of relational terms is initially context dependent; linguistic development generates…

Presents a study of task liking and intrinsic motivation using self-esteem, task label, and feedback analysis of variance. Reports that, for subjects with high self-esteem, feedback had strong impact on liking of a difficult task. Concludes that, for subjects with low self-esteem, feedback had strong impact on liking easy tasks. (DK)

Looks at teaching methods and the effects on student performance. Examines beginning teachers interactions with 84 nonmusic major students. Assesses components of proactive teaching and self-perceptions of success. Focuses on teacher feedback in relation to student success. Recommends professionals apply task analysis principles to music learning…

Describes a study designed to demonstrate that child pedestrian training objectives may be identified systematically through various task analysis methods, making use of different types of empirical information. Early approaches to analysis of pedestrian tasks are reviewed, and an outline of the Traffic Research Centre's pedestrian task analysis…

Surveys 101 wind instrumentalists to reveal major differences in the pattern of influences leading to the re-creative skill of performing a repertoire of rehearsed music for a formal examination compared to the creative ability of improvising. Uses a path analysis to determine links between the data and theoretical model. (MJP)
