This paper argues that the answer to the question, what has to be learned, needs to be established before the question, how is it learned, can be meaningfully addressed. Based on this conviction, some of the limitations of current and past research on skill acquisition are discussed. Motivated by the dynamical systems approach, the question of “what has to be learned” was tackled by setting up a non-linear mathematical model of the task (i.e. learning to make sideways movements on a ski apparatus). On the basis of this model, the phase lag between movements of the platform of the apparatus and the actions of the subject was isolated as an ensemble variable reflecting the timing of the subject in relation to the dynamics of the apparatus. This variable was subsequently used to study “how” the task was learned in a discovery learning experiment, in which predictions stemming from the model were tested and confirmed. Overall, these findings provided support for the hypothesis, formulated by Bernstein (1967), that one of the important effects of practice is learning to make use of reactive forces, thereby reducing the need for active muscular forces.
In addition, the data from a previous learning experiment on the ski apparatus—the results of which had been equivocal—were reconsidered. The use of phase lag as a dependent variable provided a resolution of those findings.
On the basis of the confirmatory testing of predictions stemming from the model and the clarification of findings from a previous experiment, it is argued that the dynamical systems approach put forward here provides a powerful method for pursuing issues in skill acquisition. Suggestions are made as to how this approach can be used to systematically pursue the questions that arise as a natural outcome of the experimental evidence presented here. 相似文献

This retrospective cross-sectional paper examines the relationship between maternal smoking during pregnancy and children’s behavioural problems at 9?years of age independent of a wide range of possible confounders. The final sample comprised 7,505 nine-year-old school children participating in the first wave of the Growing Up in Ireland study. The children were selected through the Irish national school system using a 2-stage sampling method and were representative of the nine-year population. Information on maternal smoking during pregnancy was obtained retrospectively at 9?years of age via parental recall and children’s behavioural problems were assessed using the Strengths and Difficulties Questionnaire across separate parent and teacher-report instruments. A quasi-experimental approach using propensity score matching was used to create treatment (smoking) and control (non-smoking) groups which did not differ significantly in their propensity to smoke in terms of 16 observed characteristics. After matching on the propensity score, children whose mothers smoked during pregnancy were 3.5?% (p?<?0.001) and 3.4?% (p?<?0.001) more likely to score in the problematic range on the SDQ total difficulties index according to parent and teacher-report respectively. Maternal smoking during pregnancy was more strongly associated with externalising than internalising behavioural problems. Analysis of the dose–response relationship showed that the differential between matched treatment and control groups increased with level of maternal smoking. Given that smoking is a modifiable risk factor, the promotion of successful cessation in pregnancy may prevent potentially adverse long-term consequences. 相似文献

The importance of friend influence as a determinant of adolescent behavior has primarily been inferred from research that has repeatedly demonstrated the behavior of friends to be similar. Homogeneity among peers, however, could also be due to a selection process whereby adolescents choose and keep friends whose behavior is similar to their own. Most previous studies have used cross-sectional designs that cannot delineate the source of peer homogeneity; this study employed sociometric data from longitudinal research on adolescent smoking and drinking to separate and examine the selection and influence processes. Although the findings indicate some support for the friend influence model, the acquisition hypothesis from the selection model accounts for substantially more of the adolescent-friend relationship. The implications of these results for past and future research concerning the role of peers in adolescence are discussed. 相似文献

This paper, based on naturalistic data, describes the acquisitional course and use of the articles a and the in young English-speaking children (18-61 months), with special emphasis on the role of individual variation. A growth modeling approach to the data reveals that children's individual acquisition schedules are similar in trend, but vary in the rate at which they omit determiners at a given point of time. This picture suggests that an analysis that presumes homogeneous development will seriously misrepresent the fluctuations between and within individuals. Interestingly, this variation does not reflect a variation in children's abilities to use determiners correctly-irrespective of the rate in which they used determiners, children seldom used determiners incorrectly. The analysis also reveals that children's optional omission of determiners in obligatory contexts, beginning at 18 months of age, gradually decreases on average by 3-4% a month until 36 months of age, and thereafter plunges by a factor of 10 to an average of 0.3% per month. At 36 month of age the majority of children use determiners at a near-mastery level (Brown, 1973). These findings provide a useful framework for theorizing about possible mechanisms underlying the nature of early language development pre- and post-36 months of age. 相似文献

The effects of cigarette smoking on first impressions were examined in an interlocking series of studies. Provided college students evaluated peers who were neither extremely attractive nor unattractive, smoking typically reduced the positivity of evaluations regardless of participants' smoking. Targets photographed with smoking material were rated, for example, to be less considerate, calm, disciplined, honest, healthy, well-mannered, and happy than when smoking material was absent. Replication with apparently older participants evaluating college students did not reveal smoking to influence ratings strongly. Further replication did not reveal smoking material simply to influence college students' ratings of an attractive professional model. These results were compared with earlier studies of the effects of cigarette smoking on interpersonal evaluation and an educational unit for deterring smoking was discussed. 相似文献

The application forms of graduate applicants to six organisations were analysed in two investigations. In the first, those features of the forms which predicted whether they were rejected or passed on for interview were discovered. These differed across organisational type, and included aspects of the way in which the form was completed and personal background factors, as well as experience and achievement. In the second investigation, the think-aloud protocols of recruiters as they read the application forms were analysed. Inferences from information rather than the information itself predicted decisions. It is concluded that careers advisers should offer instruction on a variety of matters relating to completion of application forms; and that graduate recruiters should continue to undertake the task of pre selection rather than seeking to 'farm it out'. 相似文献

In this paper the authors review the literature on biological and treatment studies of post-traumatic stress disorder (PTSD) and present current unifying hypotheses regarding the pathophysiology. The psychophysiological studies stress overarousal, while endocrine studies suggest a decreased Cortisol production in denial and low symptom states with increases in highly symptomatic states. Suggestive evidence is provided that PTSD is associated with permanent changes in brain mechanisms involving the locus coeruleus, amygdala, and the hypothalamo-pituitary-adrenal axis. Drug treatments are promising but not fully satisfactory as yet. Directions for further research are provided. 相似文献

The issue of smoking and Jewish law is explored. After the dangers from smoking are cited, various precedents in Jewish law are presented as the basis for confronting the matter of smoking. Arguments are suggested for strictly prohibiting smoking. The matter of the effects of smoking on the non-smoker is the subject of much research, and the dangers posed to the innocent bystanders are an added dimension pointing to the hazards of smoking and therefore indicating that it should be prohibited.Rabbi Dr. Reuven P. Bulka is editor of theJournal of Psychology and Judaism, published by Human Sciences Press for the Center for the Study of Psychology and Judaism in Ottawa, Canada. 相似文献

This study examined a functional strategy for investigating audience responses to motivationally-based persuasive appeals. It was predicted that people exposed to advertisements informing them how they could satisfy personally relevant motivations through volunteering (i.e., functionally matched messages) would judge these ads to be more persuasive, more emotionally positive, and would report being more likely to volunteer than people exposed to advertisements unrelated to their personally relevant motivations (i.e., functionally mismatched messages). These predictions were confirmed in an experiment wherein participants whose attitudes toward volunteerism served a Social Adjustive, Value Expressive, Utilitarian, Knowledge, or Ego Defensive function viewed advertisements promoting volunteerism that either matched or mismatched their personally relevant motivations. Results confirmed predictions as participants responded more favorably to the functionally matched than mismatched messages. The implications of this research for understanding the mechanisms by which functionally matched messages exert persuasive influence and the ramifications of the research for the practice of volunteerism are discussed. 相似文献

The changing emphasis on the aims of performance appraisal systems is discussed, with particular reference to the notion of appraisal as a motivating mechanism. The contention of the Total Quality school that the traditional focus on the assessment function of appraisal is counterproductive is supported, and some data are presented illustrating the doubtful value and accuracy of appraisal ratings, both for evaluating staff and as validation criteria for personality measures. Some implications of recent organizational changes for the development role of performance appraisal are reviewed, with particular reference to upward feedback and competency-based appraisal. Finally, the emerging shape of a new approach to meeting the purposes formerly served by appraisal systems is described. 相似文献

This study examines the relationship betweenroles (work and family) and well-being (happiness andsymptoms of distress) in a sample of employed Malaysianwomen, made up of both Malays (N = 288) and Chinese (N = 92). The two groups were similar in termsof their socioeconomic status, as measured by education,occupation, and family income. Both quantitative andqualitative analyses were used. Results of the quantitative analysis showed that aftercontrolling for the demographic variables of age, race,and occupational group as well as the personalityvariable of negative affectivity, job autonomy predicted both measures of well-being. Happiness was alsopredicted by spouse support. The qualitative resultsprovided another aspect into women's perceptions oftheir roles. The women's replies to questions on their preference for employment, theirhusbands' preference for them to work, their reasons forworking, the importance of work and family, child care,and their overall reports of work and family richly complemented the findings of the regressionanalysis. These findings are discussed with respect tothe general literature on women's roles and well-beingas well as within the context of the Malaysiansociety. 相似文献
