Visual cues have an important role in food preference for both rats and humans. Here, we aim to isolate the effects of numerosity, density, and surface area on food preference and running speed in rats, by using a forced-choice maze paradigm. In Experiment 1, rats preferred and ran faster for a group of multiple smaller pellets rather than a single large pellet, corroborating previous research (Capaldi, Miller, & Alptekin Journal of Experimental Psychology: Animal Behavior Processes, 15(1), 75–80, 1989). Further experiments tested the prevailing hypothesis that multiple food pieces are more reinforcing because they occupy a larger surface area. Experiment 2 controlled for numerosity by utilizing a continuous food: mashed potatoes flattened to cover a larger surface area or rounded into a ball. The rats preferred and ran faster for the flattened potatoes, suggesting surface area plays a role in quantity estimations. Finally, in Experiment 3, rats displayed no preference or difference in running speed between a group of scattered and clustered pellets when number of pellets were kept constant. Taken together, these results suggest that density has an important role in food perception—that is, the rewarding effect of higher numerosity or larger surface area is removed when the food does not fill out the entire space. Alternative explanations and implications for human diet are discussed. 相似文献

The study was concerned with assessing the effectiveness of sensory integrative therapy as an intervention method on a group of grade one children ‐‐ predicted to be “at risk” for later reading failure. Following two half‐hour therapy sessions per week over twenty‐four weeks, the experimental group performed significantly higher than the control group on measures of reading ability. These gains were maintained over a two‐year non‐intervention period. 相似文献

ABSTRACTStudies have found that Faculty–Student Interaction (FSI) has many positive benefits for students including academic support, professional development, mentoring, and career planning. Research-intensive universities exhibit the lowest levels of faculty–student interaction within higher education. This article utilises qualitative methods to explore faculty, student, and staff perceptions of faculty–student interactions, particularly those that take place out of the classroom, at a research-intensive public U.S. university. We identify social distance between faculty and students based on unequal status within a rigid, hierarchically-organised culture as a key barrier to FSI. We then discuss methods that some of the faculty in our study used to mitigate their social distance with students in an effort to increase FSI. 相似文献

Conclusion The ever increasing demands on guidance and counseling programs has added new responsibilities to the tasks of the counselor specifically in the area of career development. Along with this increase in responsibility, the issue of accountability has been added. Career information delivery systems assist the counselor in meeting the need for accurate, relevant occupational and educational information that can be disseminated in a timely efficient manner. Therefore, CIDS should be a vital part of all comprehensive career guidance and counseling programs.Mary Elizabeth McCormac is an Occupational Information System Specialist, National Occupational Information Coordinating Committee, Washington, D.C. 相似文献

Technology and millennials have created a shift in the world and how it operates. This impact has been experienced in the field of occupational therapy education. As a result of this paradigm shift, an analysis of effective teaching methodologies was carried out to assess the most effective way to engage the millennials in an analysis of occupation process, which is a critical foundation for effective critical thinking and clinical practice for occupational therapists. An action learning assignment was utilized to bridge this gap. The action learning assignment immersed the students in a safe learning environment that recreated many types of domains that needed to be analyzed. As a result, the students experienced first-hand the outcomes of effective and ineffective analysis and problem-solving during their action learning project. Therefore, the students were able to reflect and critically think through alternatives and hear about other students' projects. Overall, the action learning project yielded positive learning and engaging outcomes. 相似文献

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a control condition that wrote summaries of those same lessons. Writing activities were 10?min long and were given approximately once a week for eighteen weeks. Student motivation was assessed via self-report surveys for achievement goals and interest in science before and after the intervention. Students in the experimental condition showed higher endorsement of mastery goals and reported greater situational interest in science topics after the intervention compared to students who summarised the lessons. Increases in situational interest predicted higher individual interest in the domain. Results indicate an instructional practice requiring just 3?hours out of a semester of instruction was sufficient to achieve these effects on motivation in science classes. 相似文献
