In Experiment I rats were trained for 21÷2 days under partial (PRF) or continuous reinforcement (CRF) conditions starting at 18, 22, 28, or 36 days of age and were then subjected to immediate extinction. At all ages there was a strong partial reinforcement extinction effect (PREE), and absolute size of PREE was greatest in the youngest rats. Rate of extinction increased as a function of age following both CRF and PRF. In Experiment II the youngest and oldest age groups of Experiment I were run under the two reward conditions of Experiment I and in a third condition, PRF with number of rewards rather than trials equated to CRF (PRF-R). The PRF-R and PRF groups were not different in extinction, and both were more persistent than CRF. The youngest rats were again more persistent than the oldest, particularly after PRF training. In Experiment III it was shown that the well-known paradoxical effect, greater reward in CRF acquisition leads to faster extinction, operates in our youngest and oldest animals, but is more pronounced in the oldest. The results are discussed in terms of whether they require different explanations than those often applied to extinction data from adult rats.  相似文献

Rats were given continuous reinforcement (CRF), partial reinforcement (PRF), or successive discrimination (D) training in an alley from 11–14 (Age 1) or 15–18 (Age 2) days of age. Reinforcement was the opportunity to suckle the dry nipples of an anesthetized dam. Following a 10-day interval, all animals were given 4 successive days of discrimination training with food pellets as reinforcement. Control groups were given only the second phase of training. In the first phase, D subjects of both ages responded appropriately to the discriminative stimuli, and the PRF subjects of both ages ran significantly slower than CRF subjects. In the second phase, only the CRF subjects of Age 1 showed behavioral discrimination. All three Age 2 groups discriminated, but the discrimination developed earliest after Phase I CRF and latest after Phase I PRF. Both Age 1 control groups showed a late-developing discrimination, but neither Age 2 control group discriminated. The results suggest that infant and preweanling rats can learn both positive and negative expectancies of appetitive events, respond appropriately, and retain and transfer these expectancies to new learning. The reinforcement value of dry suckling and the effects of stimulus preexposure in infant rats are also discussed.  相似文献

Placed on a meliorative‐pejorative scale the terms sophist and sophistry allow varying interpretations, according to the types of sophistry, the nature of the sophists’ teachings, and changing meanings of the terms themselves. This paper examines some current misconceptions about the sophists and urges that critics consider both merits and faults of sophists in assessing their role in ancient education.  相似文献

The importance of non-school educational stimuli which arise in “normal” everyday life (mainly through experience and “learning from life”) and the contribution of such stimuli to the educational development of young people are often underestimated. The educational value of the widely differing casual educational structures in family and peer relationships is often not fully appreciated in educational research until such structures are combined with formal school education. So far, researchers have only just begun to explore the value of informal education and to venture beyond the “traditional” limitation of empirical educational research in Germany to formal, institutionally organised education and competence acquisition processes for pupils. In recent years, attention has not only been directed towards the family as an independent place of education—studies have also focused on real life informal interaction situations in peer relationships and their importance as significant educational factors in the context of unsupervised child daytime activities. The researchers tend to regard the family as a “different type of educational sphere” and peer relationships as social interactions between equals with considerable educational potential, involving social and cultural exchange processes which constitute “everyday education” and which differ in their effects depending on the milieu. In view of the enormous differences in the way in which children and young people are integrated into family and peer-based everyday situations, it is important to point out the high educational significance of family and peer relationships for informal education, and this must always be analysed in relation to the social milieu of the family of origin and the type of school attended by the young people. The existing research initiatives and results are discussed here in relation to various research questions. The varied considerations in relation to the significance and impact of peer relationships and the existing approaches adopted in research serve as a starting point for further suggestions for future research, and these desirable new directions in research are then discussed from a theoretical and methodological perspective.  相似文献

Teacher–student trust is associated with the social and emotional development of students, their school connectedness and engagement, and their academic achievement. However, few studies have examined how trust develops between teachers and students in ninth grade, a critical year in high school for students to start off on-track. Even less research has examined how teacher–student trust develops from the perspective of students to help identify specific teacher classroom practices that are effective at doing so, particularly at the start of the school year when students’ relationships and connections to high school are just beginning to take shape. Drawing on data from a longitudinal, qualitative study of ninth-grade teacher–student relationships in one neighborhood public high school in Chicago, this study highlights three critical classroom practices that appear particularly effective for helping to build trusting teacher–student relationships during the first 10 weeks of high school. Highlighting the perspectives and insights of ninth grade students, this analysis finds that (1) the priority that teachers place on specific classroom practices, and (2) the timing of when these practices are used by teachers, are both critical in establishing teacher–student trust—an essential ingredient in helping ninth grade students gain important social and school connections during their transition to high school. By highlighting the voices of ninth grade youth, this study provides valuable insights for educators aiming to use specific classroom-based practices that are essential for helping ninth grade students make valuable school connections and get on-track right from the start of the year.
