In this study we examined alternative item types and section configurations for improving the discriminant and convergent validity of the GRE General Test. A computer-based test of reasoning items and a generating-explanations measure was administered to a sample of 388 examinees who previously had taken the General Test. Confirmatory factor analyses indicated that three dimensions of reasoning—verbal, analytical, and quantitative—and a fourth dimension of verbal fluency based on the generating-explanations task could be distinguished. Notably, generating explanations was as distinct from new variations of reasoning items as it was from verbal and quantitative reasoning. In the full sample, this differentiation was evident in relation to such external criteria as undergraduate grade point average (UGPA), self-reported accomplishments, and a measure of ideational fluency, with generating explanations relating uniquely to aesthetic and linguistic accomplishments and to ideational fluency. For the subset of participants with undergraduate majors in the humanities and social sciences, generating explanations added to the relationship with UGPA over that contributed by the General Test. 相似文献

In recent experiments in which the social influences on feeding in Mongolian gerbils were investigated, observer gerbils acquired food preferences from conspecific demonstrators only if the demonstrators and observers were either related or familiar. Even then, the effects of demonstrator gerbils on observers’ food choices lasted less than 24 h. In similar experiments with Norway rats, the familiarity/relatedness of demonstrators and observers had little effect on social learning, and the demonstrators’ influence on observers’ food choices lasted many days. We examined the causes of these differences and found that, after observer gerbils interacted with either unfamiliar or familiar conspecific demonstrators that had been fed using procedures typically used to feed demonstrator rats, they showed long-lasting social learning about foods, whereas observer rats interacting with conspecific demonstrators that had been fed as demonstrator gerbils normally are fed showed effects of familiarity/relatedness to demonstrators on their social learning about foods. Procedural differences, rather than species differences, seem to be responsible for reported inconsistencies in social learning about foods by rats and gerbils. 相似文献

Following interaction with a “demonstrator” rat, an “observer” rat prefers that diet eaten by its demonstrator prior to their interaction (Galef & Wigmore, 1983). The present series of studies demonstrates that such demonstrator influence on observer diet preference can be found in: (1) first-generation laboratory bred wild rats as well as domesticated rats, (2) food-deprived as well as nondeprived observers, (3) unfamiliar as well as familiar demonstrator-observer pairs, (4) both 21-day-old and adult observers, and (5) rats selecting fluids as well as solids for ingestion. These data indicate that the social transmission of information concerning distant diets is a general and robust phenomenon, observable under a wide variety of experimental conditions. 相似文献

Naive “observer” rats that interact with conspecific “demonstrators” fed a distinctive food increase intake of the food their demonstrators have eaten. Here we found that observer rats that had interacted simultaneously with 2 demonstrator rats, 1 fed a distinctively flavored, protein-poor food, the other a distinctively flavored, protein-rich food, did not prefer the former. Similarly, observer rats ate equal amounts of two distinctively flavored foods after interacting simultaneously with 2 demonstrator rats, 1 that had consumed all food available to it, the other fed from a surplus of the second food. Last, observer rats that had interacted with both a “trustworthy” demonstrator (1 an observer had learned ate only nutritious foods) and an “untrustworthy” demonstrator (1 an observer had learned ate noxious substances) did not prefer unfamiliar foods eaten by trustworthy demonstrators to those eaten by untrustworthy demonstrators. These findings suggest limits on social information observers use in selecting foods. 相似文献

New visuality in art/science pedagogies challenges teachers to rethink their curriculum and the role of digital new media in facilitating conceptual thinking and the role of the creative representation of knowledge. Recent neuroscientific research on cognition, perception, memory, and emotion inform and provoke implications for 21st-century learning. Analysis of student artwork uncovers pedagogical challenges for teachers. Teachers use visual learning and its forms of higher process thinking to allow students to make cognitive connections with images, giving them the capacity to integrate concepts for the communication of art/science learning. Examples of student learning from years 3–5 and 15–17 illustrate these ideas. 相似文献

Previous motor learning studies examining the effects of practicing to catch one-handed under varying informational constraints on subsequent skill acquisition are equivocal, perhaps due to the use of relatively inexperienced adult participants. Ecological theory predicts that directing the learner's search for information in the perceptual-motor workspace can enhance skill acquisition. This study manipulated visual informational constraints on novice children (ages 9-10 years) learning to catch one-handed. A crossover transfer design was implemented in which one group acted as controls while two other groups practiced either without visual restrictions before transferring to full vision, or vice versa. The data indicated that learners forced to seek additional information sources under restricted viewing conditions demonstrated a greater positive, accumulative residual effect on acquiring a catching skill. The findings contradict current work on the specificity of practice hypothesis and suggest that varying visual informational constraints to encourage exploratory practice may represent a significant pedagogical approach to motor learning in sport. 相似文献
