In Experiment 1, two groups of female rats were trained in a triangular pool to find a hidden platform whose location was defined in terms of a single a landmark, a cylinder outside the pool. For one group, the landmark had only a single pattern (i.e., it looked the same when approached from any direction), while for the other, the landmark contained four different patterns (i.e., it looked different when approached from different directions). The first group learned to swim to the platform more rapidly than the second. Experiment 2 confirmed this difference when female rats were trained in a circular pool but found that male rats learned equally rapidly (and as rapidly as females trained with the single-pattern landmark) with both landmarks. This second finding was confirmed in Experiment 3. Finally, in Experiment 4a and 4b, male and female rats were trained either with the same, single-pattern landmark on all trials or with a different landmark each day. Males learned equally rapidly (and as rapidly as females trained with the unchanged landmark) whether the landmark changed or not. We conclude that male and female rats learn rather different things about the landmark that signals the location of the platform.  相似文献

Changes in early adolescents' self-reported cheating behaviors in mathematics before and after the transition from middle school to high school are examined. Students were surveyed in school regarding their cheating behaviors in math, and the motivational goal structures perceived in their math classrooms. Surveys were completed twice during the eighth grade (during middle school) and once at the end of the ninth grade (at the end of the first year in high school). Results indicated that self-reported cheating did not change in the year prior to the high school transition, but that reported cheating increased after the transition. Additional analyses indicated that across the high school transition, self-reported cheating in math increased for students who moved from high mastery to low mastery-oriented classes after the transition, and for students who moved from low performance to high performance-oriented classes; in contrast, self-reported cheating decreased for students who moved from low to high mastery-oriented math classrooms.  相似文献

It is broadly acknowledged that effective serials management supports and requires a close link between the staff in technical and public services. More recently, new technological opportunities combined with changes in library organization and administration have greatly facilitated this linkage. The nature and structure of a library’s organization can aid in and benefit from this connectedness. Departments in the University of Louisville’s public and technical services areas began a cooperative effort to maintain serials records in the online catalog in the early 1990s. With reorganization in the late 1990s, a new team structure emerged which further facilitated this effort. In return, this cooperation and the tools that it has created support the teams in a new user-centered approach to serials management.  相似文献
