The author investigated the longitudinal relations between theory of mind (ToM) understanding and perceptions of self and social conversations in 17 school-aged children (12 girls, 5 boys, age 8–12 years). ToM was assessed at Time 1 (T1; M age = 8 years 5 months, SD = 8.7 months, and perceptions of self and conversational experiences assessed two years later at Time 2 (T2; M age = 10 years 4 months, SD = 7.9 months. Most importantly, longitudinal findings showed that children who scored relatively high on ToM at T1 reported relatively lower perceptions of self-worth and higher number of mental states verbs in their perceptions of peer and family conversations at T2. Significant negative longitudinal associations were found between children's number of siblings and their perceptions of self-worth (T1) and number of cognitive terms in their perceptions of peer and family conversations (T2). Frequency analysis suggested that girls’ perceptions of conversations referred to more social and psychological aspects of self and relationships, whereas boys focused mainly on physical activities. Most children were more likely to prefer listening to talking during social conversations. The majority of children reported feelings of mixed or ambiguous emotions during experiences of silence. Implications for socioemotional and cognitive development in early adolescents are discussed.  相似文献

This investigation studied variability in visual thresholds for six subjects for 50 consecutive days. The results show the following:

1. Session-to-session variability agrees closely with the variability estimates made by Hecht and Zegers.

2. No periodic or cyclic trends appeared for the group or for any individual subject.

3. For all six subjects for the first 15 days of testing, a learning phenomenon was observed for the mean and standard-deviation data. There was a slow rise over the last 10 days of testing for the mean, but not for the standard-deviation data. (A discussion of the possible causes of the rise of the mean over the last 10 days suggested the influence of extraneous factors, such as boredom and fatigue.)

4. No effect of the menstrual cycle upon the threshold values was found.

Abstract

Spanish adolescents’ dominant achievement goals and their specific profiles were explored in a physical education context. A sample of 385 students (207 males and 178 females, M = 14.2 years) completed a questionnaire that included 2x2 achievement goals (AGQ-PE), dominant achievement goals, affectivity (PANASN), perfectionism (IPI) and outcome variables such as satisfaction with life (SLS), and intrinsic motivation, extrinsic motivation and amotivation (PLOC). Eighty-seven percent of participants showed dominant achievement goals, the highest percentage was mastery-approach (66%). Patterns found were consistent with the theoretical framework. Students that showed dominant mastery-approach achievement goals had a positively valenced profile. Those that showed performance-approach dominance had a positive and negative valenced profile. The ones that showed performance-avoidance had a negative valenced profile. Finally, subjects that showed mastery-avoidance dominance had a neutral valenced profile.  相似文献

The purpose here is to explore why and how to develop an emerging form of integral leadership—called evolutionary co-leadership—that is responsibly dedicated to the co-evolution of life and humanity on Planet Earth. After offering some fresh distinctions about leadership, this article calls for a shift to a radically new development paradigm, and identifies key qualities and practices of evolutionary co-leadership. It then shares some views on the multiplying effects of an integral approach to co-leadership development—in the context of transforming education—and concludes with some avenues to disseminate this emerging leadership form, mainly to deal constructively with what Barbara Marx Hubbard (2001) calls the current “birthing pains” of a new civilization.  相似文献

The history of science must be introduced onto the curriculum, scientific culture must be developed if the young are to receive a global, healthy understanding of science and technology.

The experiment pioneered by INSERM clubs is, from this point of view, exemplary.  相似文献

This is an account of the extended assessment of a 22-year-old man who was initially sent for a court report, having been accused of setting fires. He had a history both of delinquency and, importantly, of childhood asthma. Although he proved unable to engage in psychotherapy, some management was provided, such as Winnicott advocates in cases of delinquency. This paper explores the symbolic meanings and functions of the patient's delinquent acts, drawing upon theoretical concepts from Freud, Aichhorn, and Deutsch. Of particular importance is the link between this patient's delinquency, his asthma, and the unresolved mourning for his dead mother which he carried not simply for himself but for his whole family.  相似文献

Two common methods of measuring socioeconomic status (SES) were examined in relation to observed parenting behaviors in a clinical sample of 89 mothers of 3- to 6-year-olds referred for treatment of oppositional defiant disorder. Families were 74% Caucasian, 9% African American, 5% Hispanic, 1% Asian, and 11% Biracial. Most children were male (75%). Parenting behaviors were measured with the Dyadic Parent–Child Interaction Coding System (DPICS) categories of prosocial talk and negative talk. Analyses were conducted with SES measured in two ways: (a) the Hollingshead Four-Factor Index of Social Status (HI) was correlated with parenting behaviors; and (b) family income, parent education (5 categories), and parent occupation (5 categories) were used to predict parent behavior. SES was significantly positively related to maternal prosocial talk. When SES was operationalized as income, occupation, and education, the model predicted three times more variance in maternal prosocial talk than the HI alone. SES was not related to maternal negative talk by either measure of SES.  相似文献

Behavioral skills training (BST) has been employed within many different populations for the reduction of problem behaviors and acquisition of new skills; however, these changes have not always maintained over time. This study evaluated the effects of a booster training for re-establishing the classroom management proficiencies that teachers had acquired previously, but had declined over a 12-month period. The single-subject experimental results showed the booster training to be effective in re-establishing teacher performance of skills as measured by both analogue role-play and in situ postassessments within the classroom. These findings suggest that a booster training utilizing BST may be an important strategy for maintaining skill performance over time.  相似文献

To identify the challenges that students must meet to engage in effective self-directed inquiry, a class was followed for three years, from the fourth through the sixth grades, as they engaged in a sequence of progressively more demanding inquiry activities. Students made substantial progress in understanding the objectives of inquiry, identifying questions, attending to evidence, identifying patterns, making controlled comparisons, interpreting increasingly complex data, supporting claims, and drawing justified conclusions. Retaining awareness of inquiry objectives and integrating influences of multiple variables in predicting outcomes were two areas that remained challenging. A comparison group of seventh graders who had not been involved in the program displayed strikingly different approaches to an inquiry task, indicating that the skills identified here are not ones that develop in the absence of appropriate kinds of educational experiences.  相似文献

Much has changed for the counseling profession in the 30 years since the founding of the Council for Accreditation of Counseling and Related Educational Programs (CACREP). CACREP, the primary specialized accreditor for the counseling profession, has been an influential participant in the growing recognition and professionalization of counseling. This article offers an overview of CACREP and accreditation and addresses some primary issues confronting CACREP, counselor preparation programs, and, in some instances, overall U.S. higher education.  相似文献
