The present paper presents a revised model of learned helplessness in humans. The conditions under which performance deficits (helplessness) or enhanced performance (facilitation) will result from exposure to objective noncontingency are defined by a number of variables that have been shown to have an impact on human helplessness. The reformulated model specifies the operation of moderating variables as they affect a number of relationships: that between objective noncontingency and the perception of noncontingency; that between the perception of noncontingency and the future expectancy of response-reinforcement independence; and finally that between the expectancy of response-reinforcement independence and the behavirol deficits associated with learned helplessness. It is argued that exposure to noncontingency can affect both the value of future reward and the perceived probability of obtaining it. Performance deficits or enhanced performance will result from the perception of noncontingency depending on the nature of this double-edged effect of exposure to noncontingent delivery of reward.  相似文献

Two experiments are reported which assess the moderating effects on learned helplessness deficits of individual differences in task-specific motivation and expectation of control. In Experiment 1 a neutral stimulus was used and in this case only high motivation subjects displayed helplessness deficits in response to noncontingency training. In addition, high motivation subjects demonstrated greater sensitivity to the noncontingency than did low motivation subjects. However, when an aversive stimulus was used in Experiment 2 the moderating effect of motivational differences was removed and this was accompanied by greater sensitivity to the noncontingency on the part of low motivation subjects. Indeed, the learned helplessness effect in Experiment 2 was more pronounced within the low motivation group. The theoretical significance of these findings is explored and directions for future research are suggested.  相似文献

Although it is generally accepted that social risk factors predict delays in early cognitive and language development, there is less agreement about how to represent such associations statistically. Using data collected prospectively on 87 African American children during their first 4 years, this study examined 3 analytic methods for describing a child's level of social risk: (a) individual risk variables, (b) factor scores derived from those risk variables, and (c) a risk index computed by tallying the number of risk conditions present. Comparisons indicated that the individual-risk-variables approach provides better overall prediction of developmental outcomes at a particular age but is less useful in predicting developmental patterns. The risk-factor approach provides good prediction of developmental trajectories when sample sizes are moderate to large. Finally, the risk-index approach is useful for relating social risk to developmental patterns when a large number of risk variables are assessed with a small sample or when other constructs are of primary interest.  相似文献

Recent work on normal personality development in children and adolescents points to several conclusions that are relevant for understanding personality pathology. First, child temperament and adult personality traits share many features in common. Second, youths' individual differences can be described in terms of the Big Five personality traits observed in adults; an integrative taxonomy of individual differences in childhood and adolescence is articulated in this article. Third, personality is already moderately stable by the preschool years, but considerable personality change occurs well into the adult years. Taken together, these findings suggest that childhood personality functioning can and should be integrated into developmental research and applied work on personality disorders.  相似文献

It is possible that statistical learning (SL) plays a role in almost every mental activity. Indeed, research on SL has grown rapidly over recent decades in an effort to better understand perception and cognition. Yet, there remain gaps in our understanding of how SL operates, in particular with regard to its (im)mutability. Here, we investigated whether participant-related variables (such as age) and task-related variables (such as speed of stimulus presentation) affect visual statistical learning (VSL) in typically developing children. We tested 183 participants ranging in age from 5 to 12 years and compared three speeds of presentation (using stimulus durations of 800, 400 and 200 msecs). A multiple regression analysis revealed significant effects of both age and speed of presentation - after attention during familiarization and gender had been taken into consideration. VSL followed a developmental trajectory whereby learning increased with age. The amount of learning increased with longer presentation times (as shown by Turk-Browne, Jungé & Scholl, 2005, in their study of adults). There was no significant interaction between the two variables. These findings assist in elucidating the nature of statistical learning itself. While statistical learning can be observed in very young children and at remarkably fast presentation times, participant- and task-related variables do impact upon this type of learning. The findings reported here may serve to enhance our understanding of individual differences in the cognitive and perceptual processes that are thought to rely, at least in part, on SL (e.g. language processing and object recognition).  相似文献

ObjectivesHistorically, the youth sport emotional response literature focused mainly on stress and enjoyment. Although research on these emotional responses has been significant, no systematic examination of these responses from a developmental perspective has been undertaken and therefore, developmental influence and implications for competitive youth sport are largely unknown. To begin to address this issue, the present study examined the developmental progression of sources of enjoyment among youth sport participants.DesignA multivariate analysis of variance (MANOVA) was used to examine the developmental differences in sources of enjoyment among younger (under 11 years) and older (over 11 years) children participating in individual and team sports.MethodsParticipants (n=152) aged 8–15 years were categorized into groups of younger and older children based on underlying cognitive-developmental criteria. Self-report measures of enjoyment, sources of enjoyment, perceived sport competence, and task and ego goal orientation were recorded.ResultsOlder children reported significantly greater enjoyment and other-referenced competency and recognition than younger children. Although all sources of enjoyment predicted enjoyment among younger children, no single source added a unique proportion of variance to the model. Competitive excitement (CE) and other-referenced competency and recognition significantly predicted enjoyment among older children. Team sport participants reported significantly greater self-referenced competency (SRC), affiliation with peers (AP), competitive excitement (CE), positive parental involvement (PPI) and enjoyment compared with individual sport participants. Finally, aligned with previous research, task orientation and perceived competence significantly predicted enjoyment.ConclusionsThe results of the present study underline the importance of understanding the developmental progression of sources of enjoyment among children and adolescents in sport. Furthermore, consideration should also be given to the nature of the sport (team or individual) children participate in for long-term enjoyment and commitment to sport.  相似文献

This paper provides an update on the current status of theory and evidence relating to children's understanding of the pretence–reality distinction. The paper starts by highlighting the striking paradox between children's early competence in pretence and their experiences of pretence–reality confusions as late as middle childhood. This is followed by a detailed review of various theories that have been offered to explain this phenomenon. Specifically, theories attributing the paradoxical findings to methodological differences between studies are reviewed and dismissed before considering the transmigration and availability hypotheses ( Harris, Brown, Marriott, Whittall & Harmer, 1991 ; Johnson & Harris, 1994 ), the role of context and the child's emotional involvement in the pretence, and the pretence continuation account ( Golomb & Galasso, 1995 ). It is argued that none of these theories alone can explain pretence–reality confusions and that these are best explained in terms of the combined influences of cognitive availability, empirical evidence of reality, context, affect and individual differences. Further research is necessary to fully explore the nature, cause and developmental trajectory of individual differences in this domain.  相似文献

This paper proposes a developmental framework for disaster studies with children that allows researchers to explore the interaction between developmental change (defined as change that is extended, self-regulated, qualitative, and progressive) and cataclysmic change. It outlines three levels of analysis related to disasters: 1) observing the harm of disasters in the context of age-related changes in children, 2) demonstrating how children are restored to age-typical developmental trajectories following disasters, and 3) investigating how specific disaster experiences are integrated over time with children's ongoing developmental processes, such as their understanding of self and their views of the world. The paper identifies existing studies at each level of the framework, outlines how these levels of analysis can be used in constructing developmental models of disaster response, and offers suggestions for expanding disaster research into additional developmental areas.  相似文献

Developmental coordination disorder: exploration of a cerebellar hypothesis   总被引:1,自引:0,他引:1  
This study explored the hypothesis of a specific cerebellar dysfunction in children with developmental coordination disorder (DCD): motor adaptation. The performance of a group of children with DCD (3 girls and 6 boys) was compared to that of a control group (5 girls and 6 boys) on a measure of motor adaptation, the prism adaptation test (PAT). Children were between 6 years 11 months and 11 years 10 months of age. Between-group differences were only found for PAT variables related to throwing accuracy, the DCD group being more variable and less accurate than the control group. While no between-group differences were found for the adaptation variables, individual data analysis revealed that only three children in the DCD group obtained normal adaptation variables. While these findings do not confirm the hypothesis of a cerebellar dysfunction, they also do not refute it. It is possible that the poor throwing accuracy of the DCD group masked the findings for some of the PAT variables. Further exploration of the function of the cerebellum among children with DCD is needed.  相似文献

The differences in spelling error features among learning disabled and normal students spelling instructionally on four grade levels of achievement were investigated. The categories of errors were determined by invented spelling research. The results indicated that the ranking of error features for each group were significantly correlated, and that the range of individual variation about the mean group pattern of spelling error variables was highly similar at each level of achievement. The findings are congruent with the theory of developmental word knowledge and support the position that learning disabled and normally achieving children acquire specific aspects of English orthography in highly similar progressions.  相似文献

Children who are profoundly and prelingually deaf and live in residential schools lack ready access to the general language environment and some opportunities of societial interactions. How does this affect their understanding of the social world To probe this question 60 deaf and 60 hearing children, ages 9, 13, and 17, were interviewed regarding friendship and social rules (a game rule, a school rule, driving law). Summary scores for each of the 4 areas yielded age and hearing differences. The major findings were: (1) the developmental pattern of responses was similar for deaf and hearing children; (2) deaf children lagged behind hearing children in their social understanding, most in game rules, least in friendship. The results were related to a constructivist developmental perspective and to previous research on socialization of deaf children.  相似文献

The term underachievement has still not been completely accepted by educators, although research findings suggest that it is associated with various developmental problems and that it begins early in a child's educational career and becomes increasingly worse with time. The achievement patterns of 1,078 fourth grade students in the public schools of west central Wisconsin were assessed by relating on a scattergram their performances on widely used achievement and intelligence tests. Underachievers, achievers, and overachievers were then determined through a regression equation. Comparisons of these groups on 9 developmental variables indicated differences favoring the overachievers and the achievers in each case. These differences reached the 1 per cent level of significance for 7 of the 9 variables.  相似文献

Children with chronic diseases have to cope with a number of potentially stressful situations. Some relate specifically to the disease and treatment, and others, relating to school and home, are shared with all children. Research has tended to focus on environmental or personal variables that influence ‘adjustment’ to the disease. In contrast, work in general developmental psychology is concerned with identifying changes in children's appraisal of what constitutes a stressful situation, and describing appropriate coping skills. It is argued that this latter approach should be integrated with work concerned with coping in childhood illness. Implications for clinical practice are considered.  相似文献

In two experiments designed to assess the effect of varying amounts of exposure to noncontingency training, it was discovered that performance decrements could be produced after relatively brief training and again after extended training. Between these conditions was a period of recovery during which no performance deficits were evident. There was also a tendency for individual differences in motivation to moderate deficits following brief but not extended training. A four-stage model is proposed to account for these results. In response to uncontrollable outcomes, individuals are said to pass through a phase of no effect, followed by temporary helplessness, recovery, and final helplessness. The model also proposes that motivational differences and perceptions of noncontingency exert independent and opposing influences on learned helplessness deficits.  相似文献

Top Ten Pressing Questions About the Development of Emotion Regulation   总被引:8,自引:0,他引:8  
The papers in this special issue highlight the diversity of methods used to study the development of emotion regulation, and the substantial progress that has been made in understanding how children learn to manage strong emotions. This commentary poses 10 questions that focus on how developmental psychologists conceptualize emotions and regulation, measure emotions in research, and understand the interplay of individual and contextual variables. The discussion here outlines issues to guide future work; answers to these substantial questions will require much additional research.  相似文献

Characterizing developmental changes in children's dual-task performance has been problematic because differences in divided attention abilities are easily confounded with differences in overall capacity. Two experiments showed that after individual differences in children's capacity for single-task performance were controlled for, age differences between second- (M = 8.1 years) and fifth-grade (M = 11.1 years) children did not exist in dual-task performance when tasks were of equal priority. However, when tasks had different priorities, only fifth-grade children could differentially allocate attention in the dual task. Results are discussed within the coordination hypothesis framework (see A. F. Kramer & J. L. Larish, 1996), which suggests that changes in dual-task performance with aging are due to changes in the ability to coordinate and control the allocation of attention. It is argued that linking the investigations of children's attention with research on attention and aging provides both methodological and theoretical benefits.  相似文献

The arithmetical performance of typically achieving 5- to 7-year-olds (N = 29) was measured at four 6-month intervals. The same seven tasks were used at each time point: exact calculation, story problems, approximate arithmetic, place value, calculation principles, forced retrieval, and written problems. Although group analysis showed mostly linear growth over the 18-month period, analysis of individual differences revealed a much more complex picture. Some children exhibited marked variation in performance across the seven tasks, including evidence of difficulty in some cases. Individual growth patterns also showed differences in developmental trajectories between children on each task and within children across tasks. The findings support the idea of the componential nature of arithmetical ability and underscore the need for further longitudinal research on typically achieving children and of careful consideration of individual differences.  相似文献

It is suggested that the dominance of observational methods in child language research with very young children has limited progress in understanding the language acquisition process. Evidence is presented that, contrary to popular belief, naturalistic methods do not guarantee ecological validity, nor are they free of task biases. Furthermore, observational studies do not necessarily provide better measures of linguistic competence than do more structured methods. Instead, it is argued that new insights from cognitive developmental research are applicable in studying language production in children younger than 3 years. A number of structured techniques are reviewed that have been used or could be used to study language production. It is concluded that a combination of methods is necessary in order to disentangle and control the many variables that enter into the language acquisition process.  相似文献
