Conclusions Although we do not understand very well what the processes are that contribute to language development, it is clear that communication plays a central role. As children strive to become increasingly skilled at communicating their ideas (White, 1959), as they have increasingly complex ideas to communicate (Piaget, 1955), and as they encounter an increasingly diverse set of people with whom to communicate (Brown, 1973), they must learn to use language which is richer and more flexible.When children come to school or to a day care center they already know a great deal about language. They have readily and actively mastered words, sentences and forms of communication which they need in their own family and community. In their new environment—the school or center—children's language development can further be fostered by adults who are receptive to children's efforts at communication. Adults who encourage children to use language in new ways, who attend to what children mean to say and who recognize that children's errors are often not mistakes, are likely to play a positive role in children's language development.Janet H. Kane and Karen Sheingold are on the Staff at Bank Street College of Education. 相似文献

H. J. Eysenck 《Higher Education》1972,1(1):39-52
In education it is important for applied research systematically to apply and test current psychological theories. However oversimplification of a theory will generally lead to inappropriate hypotheses and hence to inconclusive or inconsistent results. In research on personality and academic attainment it has been common to derive hypotheses about the effect of neuroticism directly from an early Hullian formulation. Examples in terms of the academic behaviour of students are used to explain recent adaptations of this basic theory. In particular it is necessary to distinguish between trait and state anxiety and to incorporate allowances for the effect of previous habit systems. Strongly established habits will control the type of behaviour elicited by drive stimuli, such as imminent examinations.Anxiety, even as a trait variable, can be seen as operating in opposite directions, facilitating or debilitating performance according to the nature of the individual and of the drive stimuli. In the progression from primary to higher education there will be a tendency for individuals whose high neuroticism adversely affects their performance to be eliminated; hence a positive correlation between achievement and neuroticism at this level might be anticipated.While there is considerable complexity in the relationship between anxiety and achievement, it is clear that introversion is consistently linked with success in higher education. This high performance is probably due to the introvert's better study habits and his ability to become conditioned easily to the predominant academic mores. In addition the build-up of reactive inhibition in extraverts during lectures or prolonged periods of study is likely to lead to avoidance symptoms in time.
Résumé Dans l'enseignement il importe que la recherche expérimentale applique avec méthode les théories psychologiques classiques pour les mettre à l'épreuve. Pourtant, la simplification abusive d'une théorie mène souvent à des hypothèses inadéquates et à des résultats non concluants ou incompatibles. Dans la recherche sur la personnalité et la réussite universitaire on a souvent voulu tirer directement d'une formulation ancienne de Hull des hypothèses sur les effets du caractère névrotique. On cite des exemples de conduite scolaire des étudiants, pour montrer quelques adaptations récentes de cette théorie fondamentale. Il faut distinguer en particulier entre l'anxiété comme trait et l'anxiété comme condition, et prendre en compte l'effet du système antérieur des habitudes. Les habitudes qui sont fermement établies modèlent les types de conduite provoqués par les stimuli significatifs, tels que, par exemple, les examens imminents.On peut voir la variable de l'anxiété, considérée comme trait, agir de façons opposées en facilitant ou en entravant la réussite en fonction des caractéristiques de l'individu et des stimulants significatifs. Dans la progression de l'enseignement primaire à l'enseignement supérieure on observe une élimination progressive des individus dont le caractère névrotique exerce un effet défavorable sur la réussite; on peut par conséquent prédire une corrélation positive entre les résults et le caractère névrotique au niveau universitaire.Bien que les rapports entre l'anxiété et la réussite soient des plus complexes, il est évident que, au niveau de l'enseignement supérieur, il y a une liaison assez forte entre l'introversion et le succès. Il est probable que le niveau élevé de réussite est dû aux meilleures habitudes de travail de l'introverti et à sa capacité de s'adapter facilement aux moeurs universitaires dominantes. En outre, l'accumulation d'une inhibition réactive chez les extrovertis, pendant les cours ou les périodes d'étude prolongées tend à produire des symptômes d'annulation.相似文献

Research on Piaget's stage 4 object concept has failed to reveal a clear or consistent pattern of results. Piaget found that 8-12-month-old infants would make perserverative errors; his explanation for this phenomenon was that the infant's concept of the object was contextually dependent on his or her actions. Some studies designed to test Piaget's explanation have replicated Piaget's basic finding, yet many have found no preference for the A location or the B location or an actual preference for the B location. More recently, researchers have attempted to uncover the causes for these results concerning the A-not-B error. Again, however, different studies have yielded different results, and qualitative reviews have failed to yield a consistent explanation for the results of the individual studies. This state of affairs suggests that the phenomenon may simply be too complex to be captured by individual studies varying 1 factor at a time and by reviews based on similar qualitative considerations. Therefore, the current investigation undertook a meta-analysis, a synthesis capturing the quantitative information across the now sizable number of studies. We entered several important factors into the meta-analysis, including the effects of age, the number of A trials, the length of delay between hiding and search, the number of locations, the distances between locations, and the distinctive visual properties of the hiding arrays. Of these, the analysis consistently indicated that age, delay, and number of hiding locations strongly influence infants' search. The pattern of specific findings also yielded new information about infant search. A general characterization of the results is that, at every age, both above-chance and below-chance performance was observed. That is, at each age at least 1 combination of delay and number of locations yielded above-chance A-not-B errors or significant perseverative search. At the same time, at each age at least 1 alternative combination of delay and number of locations yielded below-chance errors and significant above-chance correct performance, that is, significantly accurate search. These 2 findings, appropriately elaborated, allow us to evaluate all extant theories of stage 4 infant search. When this is done, all these extant accounts prove to be incorrect. That is, they are incommensurate with one aspect or another of the pooled findings in the meta-analysis. Therefore, we end by proposing a new account that is consistent with the entire data set. 相似文献

A post hoc matching design was used to compare children who participated in the Home Instructional Program for Preschool Youngsters (HIPPY) throughout Arkansas to children from the same classrooms who had no preschool experience and children who had other preschool experiences in the third and sixth grades. The program showed modest positive impact on school suspensions, grades, classroom behavior, and achievement test scores at both grade levels. 相似文献

New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question’s importance in understanding whether tool behavior is transmitted via social, genetic, or environmental means. For social transmission to account for tool-type variation, copying must utilize a mechanism that is action specific (e.g., pushing left vs. right) as well as context specific (e.g., pushing a particular object vs. any object). To determine whether crows can copy a demonstrator’s actions as well as the contexts in which they occur, we conducted a diffusion experiment using a novel foraging task. We used a nontool task to eliminate any confounds introduced by individual differences in their prior tool experience. Two groups had demonstrators (trained in isolation on different options of a four-option task, including a two-action option) and one group did not. We found that crows socially learn about context: After observers see a demonstrator interact with the task, they are more likely to interact with the same parts of the task. In contrast, observers did not copy the demonstrator’s specific actions. Our results suggest it is unlikely that observing tool-making behavior transmits tool types. We suggest it is possible that tool types are transmitted when crows copy the physical form of the tools they encounter. 相似文献

In the Netherlands, as in most other European countries, closed captions for the deaf summarize texts rather than render them verbatim. Caption editors argue that in this way television viewers have enough time to both read the text and watch the program. They also claim that the meaning of the original message is properly conveyed. However, many deaf people demand verbatim subtitles so that they have full access to all original information. They claim that vital information is withheld from them as a result of the summarizing process. Linguistic research was conducted in order (a) to identify the type of information that is left out of captioned texts and (b) to determine the effects of nonverbatim captioning on the meaning of the text. The differences between spoken and captioned texts were analyzed on the basis of on a model of coherence relations in discourse. One prominent finding is that summarizing affects coherence relations, making them less explicit and altering the implied meaning. 相似文献

The purpose of this study is twofold: first, to examine to what extent the time students work on paid jobs is related to study‐time (class attendance and time devoted to self‐study) and second, to what extent the time students work on paid jobs is related to achievement. A number of 120 students from the problem‐based Faculty of Health Sciences in the Netherlands kept a time‐diary. Academic achievement was measured by using scores on the block‐test. The results showed that working about four to eight hours per week on paid jobs (as opposed to working less than four hours per week or to working intensively, more than 8 hours per week) actually is positively related to study‐time. Test‐scores are not significantly different among students who are not working on jobs, work some hours, or work a lot. 相似文献
