Three shaved adult male albino rats were trained to press a lever to replace a hot air drive condition (50° C) with either a small reinforcer (32° C) or a large reinforcer (14° C). Following the 10-sec reinforcer, the drive condition was either reinstated immediately (no delay) or after a 15-sec exposure to the drive temperature, during which the bar was withdrawn (delay). Response rate during the no-delay procedure was faster for the small reinforcer than for the large. This relation reversed during the delay procedure. The former observation is similar to a satiation effect and the latter resembles an incentive effect.  相似文献

The implementation of a Decision Support System (DSS) is, all too often, a technical success but an organizational failure. EDUCOM's Financial planning Model (EFPM) is a DSS used by many colleges and universities. This paper examines the perceived success of EFPM and the relationship between success and organizational services — the integrator functions — that support EFPM's use. The study finds that the integrator functions are significantly related to success. In addition, institutions that use EFPM have developed the integrator functions on their campuses, while institutions that no longer use EFPM did not do so. The paper suggests several theoretical and practical implications of the research.  相似文献

During the past several years measurement and instructional specialists have distinguished between norm-referenced and criterion-referenced approaches to measurement. More traditional, a norm-referenced measure is used to identify an individual's performance in relation to the performance of others on the same measure. A criterion-referenced test is used to identify an individual's status with respect to an established standard of performance. This discussion examines the implications of these two approaches to measurement, particularly criterion-referenced measurement, with respect to variability, item construction, reliability, validity, item analysis, reporting, and interpretation.  相似文献

In this study the development of causal attributions about reading within low-income families was examined. Specifically, relations between children's reading achievement and their causal attributions were investigated as well as relations between the children's attributions about themselves and their parents’ attributions about them. A total 513 students from Grades 3, 6, and 9, and one parent of each student, all from low-income families, participated. Students and parents independently rated the importance of seven causal variables (effort, intellectual ability, liking for reading, the teacher, help at home, difficulty of reading material, and luck) for the students’ good and poor reading outcomes. The major findings were that (a) at each grade, students’ attributions were reliably related to their reading achievement on the Gates–MacGinitie reading comprehension test, with attributions to ability, liking for reading, and help at home especially critical; (b) at each grade, parent attributions were reliably associated with student attributions; and (c) as students’ grade in school increased, they focused more on themselves and less on others as causal determinants of their reading performance. The implications of these findings for research and education are discussed.  相似文献

The review acknowledges that research on the family and its contribution to achievement in ethnic minority children is important. Past research and theorizing suggest the need for new directions, however. For example, research in educational achievement predicts educational failure for African-American students and educational success for Asian-American students. Little differentiation is made either among African-Americans or among Asian-Americans of different cultural, language, immigration, and economic backgrounds. The theory and design of research on family and educational achievement have been influenced by prevailing societal stereotypes. Research and policy implications of this review include the need to move toward cultural/ecological theories of achievement socialization and development.  相似文献

Following treatment in a therapeutic day treatment program, a group of 35 maltreated children were compared to a matched group of 35 maltreated children who had not been enrolled in a therapeutic day treatment program. The results of matched pairs t-test analyses indicated that the treatment subjects had significantly higher developmental scores in five areas of development--fine motor, cognitive, gross motor, social/emotional, and language. Further, pretest and posttest comparisons of the percentile scores of the treatment group indicated that the posttest scores were significantly higher than the pretest scores. This study demonstrates that remediation of developmental delays in maltreated children under the age of 6 years can be accomplished through an intensive day treatment program.  相似文献

Effects of atypical patterns of fetal growth on newborn (NBAS) behavior   总被引:2,自引:0,他引:2  
Newborn infants who showed anthropometric signs of atypical patterns of fetal growth were compared with infants of appropriate growth on the Neonatal Behavioral Assessment Scale (NBAS) and on recently developed supplementary items. The sample consisted of lower-socioeconomic-status families in San Juan, Puerto Rico, and included teenage and older mothers. Infants with atypical patterns of fetal growth showed lower scores than did infants of appropriate growth on the NBAS orientation, motor, and reflex clusters and on 15 of the 18 supplementary scores. Gestational age was covaried and showed independent effects on 6 items. Differential effects on measures of state and autonomic function were also found when the effects of the ponderal index were held constant. The results suggested that neonatal behavior is related to multiple indices of fetal growth patterns that may indicate early versus late nutritional insult. Supplementary NBAS items do not improve the discriminability of the NBAS but may help explain the basis for observed group differences.  相似文献

The present study aimed to describe the methods of writing used by university faculty and to explore relationships between method and productivity in writing. The survey reported here examined the cognitive strategies, tools, work scheduling, environment, and rituals used by 121 science and engineering faculty members in writing technical documents such as journal articles. The most commonly reported methods (e.g., the cognitive strategy of mentally planning large units of text structure and selecting a pen or pencil for a tool) were uncorrelated with reported productivity. Selecting a quiet work environment was the only typical habit that was associated with high productivity. Three other aspects of writing method were also related to high productivity, but they were not widely employed. These were using a dictation machine, preparing detailed written outlines before beginning a first draft, and the ritual of exercising vigorously before or during a writing session.  相似文献

Andreas Libavius’ (c. 1555–1616) three part collection of letters, the Rerum chymicarum epistolica forma ... liber (1595–1599) is a particularly important text in fashioning the subject of chemistry as a demonstrative science and as a didactic discipline. Where Libavius’ Alchemia, which some have claimed to be the first textbook of chemistry, had mostly a humanist agenda, the Rerum chymicarum ... liber more directly sought to wrest the subject of “chemistry” away from Paracelsian adepts, and established the methodological basis for a specific form of knowledge suitable to the university. Making use of Aristotle’s Posterior analytics Libavius created a “floor-plan” for chemistry that integrated practical experience with natural philosophy, and could thus, he claimed, penetrate more deeply into the structure of nature than other academic disciplines.  相似文献

Questionnaire data collected from male and female university students 25 years of age or older were used to investigate correlates of their performance, satisfaction, and adjustment in college. Men reported lower levels of performance and satisfaction. Multiple regression analyses of predictors of college grade-point average, satisfaction with college, and affective changes occurring while in college indicated that these three measures were predicted by demographic variables, by aspects of the college experience, by the external out-of-college responsibilities of these students, and by their goals. Each of the three dependent measures was predicted by a different subset of these variables.  相似文献
