Mothers are currently under-represented in the literature on anorexia, including research on treatment, with most research focussed on female adolescents. This raises questions about how adult women and particularly those who are mothers, experience eating disorder treatment. This study provides a phenomenological exploration of lived experiences of seeking and receiving professional help and interactions with health professionals for six white heterosexual mothers who experienced anorexia while raising their children. Four themes are reported that capture the women's diverse experiences of seeking and receiving support for anorexia: (1) conflict between mothering and seeking help; (2) experiences of feeling blamed, poorly treated or misunderstood by health professionals; (3) positive experiences of seeking and receiving support; and (4) the importance of ongoing support. The women's experiences suggest that healthcare professionals should adopt a more holistic approach that acknowledges the subjective reality of the client (including their mother status) when working with mothers experiencing anorexia.  相似文献

Empirical findings and theorizations of both imitation and selective trust offer different views on and interpretations of children's social learning mechanisms. The imitation literature provides ample documentation of children's behavioural patterns in the acquisition of socially appropriate norms and practices. The selective trust literature provides insights into children's cognitive processes of choosing credible informants and what information to learn in future interactions. In this paper, we place together findings from both fields and note that they share analogically similar theoretical underpinnings and offer explanations that are complementary to each other. We contend that children's imitative tendency may be due to their selection of in-group members as cultural experts, who serve as reliable sources of conventional information. Moving forward, we note the importance of evaluating individual differences and cultural factors to provide a more holistic understanding of universality and variation in children's social learning mechanisms.  相似文献

Standard procedures for estimating item parameters in item response theory (IRT) ignore collateral information that may be available about examinees, such as their standing on demographic and educational variables. This paper describes circumstances under which collateral information about examineesmay be used to make inferences about item parameters more precise, and circumstances under which itmust be used to obtain correct inferences.This work was supported by Contract No. N00014-85-K-0683, project designation NR 150-539, from the Cognitive Science Program, Cognitive and Neural Sciences Division, Office of Naval Research.

Constructions of emotion: Discrepancy,arousal, and mood   总被引:1,自引:0,他引:1  
An interactive adventure-type computer game was used to explore the constructive components of emotional experience — sympathetic nervous system arousal and evaluative cognitions — postulated by discrepancy/evaluation theory. Manipulations of expectations produced significant and large heart rate changes for both positive and negative discrepancies. Autonomic response also reflected the degree of interruption/discrepancy produced by an event. Negatively toned (discrepant) events tended to produce significant intensity and higher overall autonomic arousal. In addition, subjects' intensity of experience was related to their autonomic response.The research and preparation of this report were supported by a grant from the Spencer Foundation. We are grateful to Carol Beards, Barbara Lagana, and Jeffrey McIntosh for assistance in data collection and data analysis. Special thanks go to Mark Wallen for programming Rogue and much of the data analysis.  相似文献

The role of the hemispheres in closed loop movements   总被引:3,自引:0,他引:3  
The purpose of these experiments was to determine if the two hemispheres play different roles in controlling closed loop movements. Subjects were asked to move to a narrow or wide target in the left or right hemispace. Reaction time (RT) was faster for the left arm of normals, only in the right hemispace, but there were no differences between arms in movement execution. Right but not left hemisphere stroke (CVA) patients showed longer RTs for the contralateral but not ipsilateral arm. The right CVA group's ipsilateral movement, especially to narrow targets was less accurate. The left CVA group's RT did not benefit from advanced information, but ipsilateral movement execution was normal. These results were discussed in terms of inter- as well as intrahemispheric control of programming and execution of closed loop movements.  相似文献

Sexual abuse, the fastest growing type of abuse complaint, often raises issues concerning the credibility of individual allegations. This paper discusses historical, developmental, and societal factors affecting children's credibility and recommended assessment methods that maximize a child's capacity to relate his or her experience. Clinical factors leading to false allegations are discussed.  相似文献

Openness to Experience and Development of Adult Identity   总被引:1,自引:0,他引:1  
ABSTRACT The formation of ego identity through exploration of alternatives and formation of commitments is a central issue in the transition from adolescence to adulthood (Erikson, 1959, Waterman, 1982) In 59 adults ranging in age from 18 to 30, independent identity scales were found to be positively correlated with age The construct of openness to experience was hypothesized to account for individual differences in identity development As predicted, openness to experience was positively correlated with ratings of current and past identity exploration, and negatively related to intensity of identity commitment A comparison of two methods of measuring ego identity showed that identity rating scales provide a more differentiated assessment of psychosocial development than does the identity status scoring method  相似文献

This study was conducted in Southern Africa in the country of Zimbabwe where 75% of the population reside in economically underdeveloped rural areas. Two groups of rural-dwelling subsistence farmers were interviewed in their homes with respect to life-style, stressors and coping mechanisms. The experimental group consisted of 62 farmers who had recently moved to a newly-developed government-sponsored farming community and the control group consisted of 75 farmers who had been resident on their farms for an average of 15 years. The results showed that subjects in the development scheme experienced more stress than those in the control group but viewed themselves as coping adequately. The development scheme appeared to be successful from a psychological perspective in that the subjects were able to continue their traditional lifestyle as well as incorporate modern values based on a cash economy.  相似文献

Computer-aided spatiotemporal imaging techniques, like those that are proving to be important in many other scientific fields, are being used to represent and study movement patterns of animals exposed to basic reinforcement contingencies. Data from a video-tracking system that provides real-time tracking of the position of an experimental animal as it moves about in a three-dimensional space can be plotted in up to three dimensions. When the data are plotted in two spatial dimensions and the time dimension, behavior is captured as continuous patterns or structures in space-time. Spatiotemporal imaging of movement patterns permits regularities to be observed that are not seen as readily in other ways such as watching videotapes of the experimental sessions or simply examining rate of responding. By providing a concise spatiotemporal representation of the movement patterns that occurred in a given experimental preparation, the imaging techniques described here represent an advancement in the scientific study of continuously flowing behavior. Although we concentrate here on movement patterns produced by basic reinforcement contingencies, the spatiotemporal imaging technology is applicable to any research topic in which movement patterns are of interest, such as foraging, place learning, sign language, and limb movement.  相似文献

Groups and individuals were compared in two experiments. In the first, two same-sex individuals or two same-sex dyads played 10 trials of a Prisoner's Dilemma matrix game (PDG) for money. Play between individuals was more cooperative and less competitive than play between groups. In the second experiment subjects played 10 trials of either PDG or mutual-fate-control (MFC) matrices. For the MFC matrix the competitive choice, which reduces the opponent's outcomes, but has no effect on own outcomes, reflects a desire to increase one's relative advantage over the opponent. Although cooperation was greater for MFC, for both PDG and MFC matrices groups were more competitive and less cooperative than individuals. A large component of the groups-individuals effect is attributed to the greater desire of groups to “win” or avoid “losing” to the opponent, regardless of their absolute outcomes.  相似文献
