Harter's Self-perception Profile for Children was designed to assess children's domain-specific judgments of their competence (scholastic, social, athletic, physical, and behavioral), as well as global self-worth. The psychometric properties and exploratory factor analysis of the profile for two Spanish samples of children (49% boys and 51% girls; M age=11.1 yr., SD=9.7), were examined (n=23 from an after-school social care center in an economically deprived neighborhood and n=120 from a private school mainly enrolling families of medium socioeconomic status). All attending children between 9 and 12 yr. old were included. Analysis showed sex differences, with girls scoring lower than boys on Athletic Competence and higher on Behavioral Conduct. Children from the economically deprived group had higher scores on Social Acceptance and lower scores on Physical Appearance. The cross-cultural analysis showed that the Spanish control group scored significantly higher than the original American control group on Global Self-worth. A Spanish validation with 9- to 12-yr.-olds clearly replicated the five-factor structure reported by Harter in 1985 and also replicated the results obtained in other European samples, showing reliable and valid psychometric properties.  相似文献

Although the theoretical importance of perspective taking has long been recognized, surprisingly little work has documented the cognitions associated with attempts to imagine another's point of view. To explore this issue and to determine whether perspective taking increases the likelihood of self-related thoughts, two experiments were carried out. In the first, a thought-listing procedure was used to assess observer cognitions; in the second, a less reactive measure was used. Instructions to imagine the self in the target's position and instructions simply to imagine the target's perspective produced increased levels of self-related cognition relative to a traditional control condition; the imagine-self condition also produced more self-thoughts and fewer target thoughts than did the imagine-target condition. The control condition produced thoughts suggesting that the observers were distancing themselves from the target. Observers receiving no instructions at all reported cognitions that closely resembled those of observers who received imagine-target instructions.  相似文献

With the aim of studying the relationship between methods of emotion regulation and quality of attachment we examined 39 infants with different patterns of attachment, of whom 20 were classified as secure (B), 12 as avoidant (A) and 7 as resistant (C), assessing the regulatory strategies adopted by them during the Strange Situation at 13 months. Secure infants used strategies of positive social engagement more than insecure avoidant infants, while resistant infants displayed greater negative social engagement and less object orientation than the other two groups. Avoidant infants adopted positive and negative hetero-regulatory strategies less than the other groups, also differing from resistant infants in their greater use of object regulatory strategies. There were no significant differences as regards self-comforting regulation. Thus, the findings showed how the most significant differences to emerge between the groups concerned hetero-regulatory strategies, developed by the infant in interaction with attachment figures, and regulatory strategies oriented towards objects. Further analysis showed how the use by part of each attachment group of the emotion regulation strategies varies, differentiating the episodes of the SSP according to their level of stress.  相似文献

The concept of heterotopia challenges political theory, which has often focused on utopic thinking. Foucault describes a heterotopia as a heterogenous space that juxtaposes in a single real place several spaces, several sites that are in themselves incompatible. Streets, squares and parks form heterotopias when their utopic purity as public space is juxtaposed with the private spaces created by the cardboard boxes and other temporary shelters of homeless people. Since citizenship has traditionally been thought of as participation in a democratic public sphere, how do heterotopias of homelessness challenge the ideas about citizenship? Based on narrative research with homeless people in Poland, I show how the homeless conceive of their marginality. Their participation or non-participation in democracy is not hidden but, on the contrary, very visible in public spaces where they are included as excluded.  相似文献

The experiences of mothers of adult offspring with Angelman, Cornelia de Lange, or Cri du Chat syndrome have not been previously explored in research. The current study focuses on experiences with social and medical services and the impact the rareness of an adult offspring’s syndrome has on the experiences of mothers. Eight mothers of adults with Angelman, Cornelia de Lange, or Cri du Chat syndrome were interviewed. Thematic Content Analysis was used to interpret the interviews. Four themes emerged from the analysis: (i) The rarity of their offspring’s syndrome, (ii) Uneven medical and social care service provision, (iii) The inertia of social care services, and (iv) Mothers as advocates. Mothers felt that the rareness of their offspring’s syndrome did not affect experiences with social care services, but did affect access to medical services and some aspects of day-to-day living. Accessing appropriate social care services was reported to be a lengthy and complex process. These data may help inform care service providers about how best to support adults with rare genetic syndromes and their families.  相似文献

SenseCam review has been shown to promote and sustain subsequent access to memories that might otherwise remain inaccessible. While SenseCam review facilitates recollection for personally experienced events, we know little about the boundary conditions under which this operates and about how underlying processing mechanisms can be optimally recruited to offset memory impairments of the sort that occur in dementia. This paper considers some of these issues with a view to targeting future research that not only clarifies our evolving body of theory about how memory works, but also informs about how memory-assistive technologies for patients might be employed to maximal effect. We begin by outlining key factors that are known to influence recollection. We then examine variability in the decline of memory function both in normal ageing and in dementia. Attention is drawn to similarities in the recollection deficits associated with depression and dementia, and we suggest that this may reflect shared underlying mechanisms. We conclude by discussing how one particular theoretical rationale can be intersected with key SenseCam capabilities to define priorities for ongoing and future SenseCam research.  相似文献

Much recent evidence shows that preschoolers are sensitive to the accuracy of an informant. Faced with two informants, one of whom names familiar objects accurately and the other inaccurately, preschoolers subsequently prefer to learn the names and functions of unfamiliar objects from the more accurate informant. This study examined the inference process underlying this preference. We asked whether preschoolers make narrow inferences about informants, broader trait-based inferences, or more global evaluative inferences. We further asked what inferences preschoolers make about a potential informant based on distinctions in the unrelated domain of physical strength. The results indicate that preschoolers make relatively narrow inferences when observing individual differences in accuracy even though they are prone to global evaluative inferences when observing individual differences in strength. Preschoolers’ burgeoning understanding of others as expert language users may underlie their selective endorsement of a more accurate informant.  相似文献

This research shows that the motivation to posses a desired characteristic (or to avoid an undesired one) results in self-perceptions that guide people’s use of base rate in the Lawyer–Engineer problem (Kahneman & Tversky, 1973). In four studies, participants induced to believe (or recall, Exp. 2) that a rational cognitive style is success-conducive (or an intuitive cognitive style failure-conducive) subsequently viewed themselves as more rational and relied more on base rate in their probability estimates than those induced to believe that a rational cognitive style is failure-conducive (or an intuitive cognitive style success-conducive). These findings show that the desired self had an influence on reasoning in the self-unrelated lawyer–engineer task, since the use of base rates was mediated by changes in participants’ perceptions of their own rationality. These findings therefore show that the desired self, through the working self-concept that it entails, constitutes another factor influencing people’s use of distinct modes of reasoning.  相似文献

The menstrual cycle has been reported to alter pain perception but the patterns differ among studies. It has been reported that estrogens may influence somatic sensory processes. The present aim was to investigate whether the perception of pain varies by phases of the menstrual cycle. 20 women with chronic low pain volunteered to participate and were asked to rate their pain each day during three successive menstrual cycles. The menstrual cycle was divided into four and five phases to be able to compare results. Analysis showed there were phase differences in pain ratings during the menstrual cycle. Regardless of whether the menstrual cycle was divided into four or five phases, women rated pain significantly higher in the menstrual and premenstrual phases than in the midmenstrual and ovulatory phases. This is consistent with other studies showing less pain sensitivity during phases of the menstrual cycle associated with high estrogen. Women with high pain frequency reported more frequently a passive coping style and catastrophizing thoughts.  相似文献
