Children confront the formidable task of assimilating information in the environment and accommodating their cognitive structures to that information. Developmental science is concerned equally with two distinctive features of these processes: children's group mean level of performance through time and the standing of individual children through time. Prevailing opinion since the inception of the mental-measurement movement has been that individual development is unstable-that individual children change unpredictably in their abilities. We report results of a large-scale controlled, multivariate, prospective, microgenetic, 4-year longitudinal study that reveals a statistically significant cascade of species-typical cognitive abilities from infancy to childhood. Infancy is a recognizable starting point of life; we find that to a small but significant degree, infancy also represents a setting point in the life of the individual.  相似文献

Changes in reward magnitude or value have been reported to produce effects on timing behavior, which have been attributed to changes in the speed of an internal pacemaker in some instances and to attentional factors in other cases. The present experiments therefore aimed to clarify the effects of reward magnitude on timing processes. In Experiment 1, rats were trained to discriminate a short (2 s) vs. a long (8 s) signal followed by testing with intermediate durations. Then, the reward on short or long trials was increased from 1 to 4 pellets in separate groups. Experiment 2 measured the effect of different reward magnitudes associated with the short vs. long signals throughout training. Finally, Experiment 3 controlled for satiety effects during the reward magnitude manipulation phase. A general flattening of the psychophysical function was evident in all three experiments, suggesting that unequal reward magnitudes may disrupt attention to duration.  相似文献

To examine the impact of early linguistic experiences on later verbal report of autobiographical memory, 13 hearing adults and 13 deaf adults born to hearing parents described events that occurred before and after the age of 10 years. The contextual, temporal, and thematic coherence of the narratives was rated. The use of emotional, perceptual, mental, and physiological states was also recorded. There were differences in the coherence of the narratives and use of internal states according to the age at which the events occurred. There were no group differences in coherence, but hearing adults provided longer narratives than deaf adults. When narrative length was controlled, deaf adults included more emotional states than hearing adults. Results suggest that early unavailability of language does not impact the coherence of adults’ narratives, although certain features of linguistic expression specific to ASL may result in greater saturation of emotional states references in autobiographical narratives of deaf adults.  相似文献

The purpose of this article is threefold: (a) to describe the relevant ethical and legal issues associated with decisional capacity among minors and to discuss the importance of these concepts for children and adolescents living with HIV, (b) to provide a framework for assessing the decisional capacity of children and adolescents with HIV, and (c) to present a model for thinking about how to use this assessment data to guide action along the protection-autonomy continuum.  相似文献

This study sought to expand scientific knowledge on psychopathic personality traits in female offenders by evaluating the relationship between MMPI–2–RF triarchic scales and self-reported external variables in a sample of 205 female offenders. Results indicated that boldness was inversely related to internalizing dysfunction, including suicidal behavior, psychosis, youth conduct problems, problems stemming from alcohol use, and a history of outpatient mental health treatment. Meanness was positively related to internalizing dysfunction as well as youth conduct problems, anger, prison disciplinary reports, and psychosis. Disinhibition was associated with a history of abuse in childhood, suicidal behavior, internalizing dysfunction, problems associated with alcohol and drug use, family history of mental illness, prison disciplinary reports for violence, number of previous criminal charges, and anger. Consistent with views of psychopathy as a configural condition, interactive effects of boldness with disinhibition and meanness were observed for multiple key external variables (e.g., conduct problems, substance use, nonsuicidal self-injurious behavior). This study provides further evidence for the triarchic conceptualization of psychopathy in female offenders and lends additional support for the validity of MMPI–2–RF triarchic psychopathy scales.  相似文献

Motivation can be undermined among first-year college students as they face a multitude of unanticipated challenges during the transition from high school to college (Compas, Wagner, Slavin, &; Vannatta, 1986 Compas , B. E. , Wagner , B. M. , Slavin , L. A. , &; Vannatta , K. ( 1986 ). A prospective study of life events, social support, and psychological symptomatology during the transition from high school to college . American Journal of Community Psychology , 14 , 241257 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]; Perry, Hall, &; Ruthig, 2005 Perry , R. P. , Hall , N. C. , &; Ruthig , J. C. ( 2005 ). Perceived (academic) control and scholastic attainment in higher education . In J. Smart (Ed.), Higher education: Handbook of theory and research ( Vol. 20 , pp. 363436 ). New York : Springer .[Crossref] [Google Scholar]). As a consequence, approximately 27% of first-year students do not return for the second year of college (Feldman, 2005 Feldman , R. S. ( 2005 ). Improving the first year of college: Research and practice . Mahwah , NJ : Erlbaum . [Google Scholar]). First-year college students (N = 336) participated in a study to examine the efficacy of an Attributional Retraining (AR) treatment designed to increase motivation and enhance academic achievement. Employing a pre–post study design spanning an academic year, we examined the impact of AR on student motivation as operationalized in terms of mastery and performance goals. Findings indicated that AR increased mastery motivation but did not affect performance motivation. Findings also demonstrated that mastery motivation mediated the relationship between AR and grade point average, suggesting that mastery motivation is a key mechanism of AR. Findings are discussed in terms of conceptual contributions to both the AR and achievement motivation literatures, and practical implications are outlined.  相似文献

A more negative implicit evaluation of unhealthy food stimuli and a more positive implicit evaluation of a weight-management goal have been shown to predict lower consumption of unhealthy food. However, the associations between these evaluations, temptation to indulge and consumption of unhealthy food remain unclear. The current study investigated whether temptation would mediate the relationship between implicit food and goal evaluations and consumption (resembling an antecedent-focused route to self-control of eating), or whether those evaluations would moderate the relationship between temptation and consumption (resembling a response-focused route). A sample of 156 women (17–25 years), who tried to manage their weight through healthy eating, completed two implicit association tasks assessing implicit food and goal evaluations, respectively. Intake of four energy-dense snack foods was measured in a task disguised as a taste test, and participants reported the strength of experienced temptation to indulge in the snacks offered. Negative implicit food evaluation was associated with lower snack intake, and temptation mediated this relationship. Implicit goal evaluation was unrelated to both temptation strength and snack consumption. The findings contribute to an understanding of how negative implicit unhealthy food evaluation relates to lower consumption, namely through the mediation of temptation to indulge in those foods.  相似文献

Taxonomies inherited from the nineteenth century have shaped the discourse surrounding the racial identity and supposed roots of Ethiopian immigrants to Israel. Through their interactions with just a few colonial actors, some of whom were Christian missionaries, others who were Jewish Zionists, a small group of young Falashas developed an elite status in Ethiopia as the true lost Jews in Africa. While most historians specializing in the history of Ethiopia do not believe the Beta Israel are a “lost tribe” of the ancient Israelites, Ethiopian immigrants have altered their self‐conceptions over the past hundred years and come to see themselves as both black and Jewish. This essay offers an alternative reading of the Beta Israel narrative, and asserts that the transformation of their social identities are embedded in a political process of racialization tied to racial ideology, and both secular and religious institutions and the State. In the process of incorporation into western society, their social identities have been transmogrified from religious others in Ethiopia to co‐religionists yet racial others in Israel.  相似文献
