Three experiments compared the learning potential of text versus outline and matrix displays. In Experiments 1 and 2, college students read or heard a passage about fish and then studied the text, an outline, or a matrix. In Experiment 3, students heard a passage about wildcats, and then studied text, outline, or matrix displays. In all experiments, the text, outline, and matrix formats were informationally equivalent. However, the two-dimensional matrix appeared more computationally efficient than the linear organized text or outline because it (a) positioned related information about fish or wildcats in closer proximity so that local relations within a single category (such as size) were learned, and (b) organized information spatially so that global relations across categories (such as size and diet) were learned. The learning potential of text, outline, and matrix displays was also examined in combination with variations in thematic organization, amount of study time, and time of testing. The most important and consistent findings were that (a) outline and matrix displays produced greater relational learning than the text, and (b) matrix displays produced greater relational learning than outlines. 相似文献

This recent study sought to examine the marketing orientations found in community, junior and technical colleges and to relate these orientations to enrollment trends within those same institutions. “High” and “low” marketing orientation campuses were defined based upon a marketing typology developed for the study. Analyses of variance revealed differences between these two types of campuses in terms of the stability of their full‐and part‐time headcount enrollments for a nine‐year period. Among other findings, the study describes the diversity of marketing approaches employed by the nation's two‐year colleges. Results of the study indicate that chief executives can look to establishing sound marketing management organizations, sensitive marketing intelligence systems, and efficient marketing planning and control systems to influence enrollment trends. 相似文献

Pigeons were trained in an intratrial interference preparation in which a horizontal or vertical line was presented for 1 sec immediately following termination of a sample (red or green). Two samples were presented successively on interference trials. Choice of the comparison corresponding to the second (target) sample was designated correct and was reinforced, and choice of the comparison corresponding to the first (interfering) sample was designated incorrect and was not reinforced. Control trials involved the presentation of a single, target sample. A horizontal line was presented upon termination of an interfering sample, and a vertical line was presented upon termination of a target sample. The results of three experiments led to the conclusion that the horizontal line acquired and capacity to reduce postperceptual processing (rehearsal) of information derived from an immediately preceding sample stimulus. These findings include (1) convergence of accuracy on control and interference trials as training progressed, (2) a reduction in accuracy on control and especially on interference trials when the correlation between sample type (interfering or target) and cue type (horizontal or vertical) was reduced to zero, (3) higher accuracy (i.e., less interference) when the horizontal rather than the vertical line followed the interfering sample, and (4) higher accuracy on single-sample trials when the vertical rather than the horizontal line followed sample presentation. 相似文献

In a recent theoretical model of Attention-Deficit/Hyperactivity Disorder (ADHD) it is proposed that a core deficit in response inhibition affects, among other things, an individual's objectivity in their reaction to events. In the context of this, the ability of boys diagnosed with ADHD objectively to differentiate their own behaviour from that of a caricatured portrayal of ADHD by Bart Simpson was examined. Four segments, each lasting 10–15 seconds, depicting ADHD related behaviours were isolated from a television episode of The Simpsons and shown in random order to 39 boys diagnosed with ADHD, their mothers, and two paediatricians. After watching each segment, the boys were asked to show how similar they believed their behaviours were to those exhibited by Bart Simpson by simultaneously placing two figures (one a replica of Bart and another representing themselves) on a chequer board. Mothers were subsequently administered the same procedure to indicate how they viewed their sons' behaviour in relation to Bart's. The distance measured between the two figures was representative of their levels of objectivity compared to a benchmark level set by the two paediatricians using the same chequer board procedure. While the results overall indicate that boys with ADHD and their mothers are able to make distinctions between caricatured and typical ADHD behaviours, the results are mediated by both ADHD subtype and the specific ADHD behaviour portrayed in the video segment. 相似文献
