From a constructivist perspective we studied the experience of motherhood in a comparative study with 15 adopted women and 15 nonadopted women, all of them also biological mothers. We used the social self grid, and it was analyzed by means of the program RECORD 5.0 and also through content analysis. Results show similarities and differences between the two groups in the construction of identity as a mother. Although in both samples the self as a mother is constructed similarly to the self in their couple relationship, this is more evident in the case of adoptive daughters, and the difference is statistically significant. The meanings attributed to their own motherhood are similar in both samples and have to do with enjoying motherhood. Nonetheless, in the adoptive sample there are more constructs related to control and doing things right, and in the biological sample there are more constructs referring to naturalness and devotion. Moreover, in the adoptive sample there appears a higher presence of cognitive conflicts and lower self-esteem, and both results tend to significance.  相似文献

Observers were instructed to point with their right arm to a mirror image of their left shoulder. Instead of pointing to the target with their real arm, they occluded the target with their mirror-imaged finger, and their real finger pointed off to the left side of the target, facts that came as a surprise to them in debriefing. The occlusion by a mirror image finger was not done to avoid double images, since it occurred in monocular conditions. That it is due to planning before pointing can be inferred from the fact that it occurred in blindfolded conditions.  相似文献

When using sample data to decide whether two populations differ, laypeople attend to the difference between group means, but largely overlook within-group variability (Obrecht, Chapman, & Gelman, 2007 Obrecht, N. A., Chapman, G. B. and Gelman, R. 2007. Intuitive t-tests: Lay use of statistical information. Psychonomic Bulletin & Review, 14: 11471152.  [Google Scholar]). We show, first, that laypeople know about and use story-implied variability when making pairwise comparisons. Then we demonstrate that participants’ sensitivity to variance in a dataset is boosted when presented in a context that implies consistent variance information. Statistical data were couched in stories about electrical conductivity measurements obtained from element samples (low-variability category) or body weight measurements from samples of peoples (high-variability category). We manipulated, between participants, whether the data variance matched or mismatched the story-implied variability. Participants who received data in a matching context showed high sensitivity to variance, while those in the mismatching condition did not. Laypeople use statistical data to make reasonable inferences when those data are provided in a context that makes sense.  相似文献

The purpose of this study was to explore how Buddhism is associated with well-being among Thai Buddhists via an application of stress process theory. Survey data were collected in 2012 from 314 Thai citizens and analysed with structural equation modelling to assess how the association between socio-economic status (SES) and well-being is mediated by stressors and resources, in particular, religious resources. The results reveal that low SES is associated with greater financial hardship and household crowding and lower sense of control, which in turn are associated with worse well-being. Furthermore, income is associated with happiness via belief in Dharma control, whereas education is associated with unhappiness via its negative association with public religiosity. Lastly, the positive influence of religious beliefs on well-being is contingent upon having a relatively high sense of control, whereas the positive influence of religious behaviours is contingent upon having a relatively low sense of control.  相似文献

Hypoglycemia is the most common adverse event associated with insulin treatment in diabetes. The consequences of hypoglycemia can be quite aversive and potentially life threatening. The physical sequelae provide ample reason for patients to fear hypoglycemia and avoid episodes. For these reasons, our purpose in this study was to develop a new measure that explores specific fear of hypoglycemia (FH) in adult patients with type 1 diabetes and to examine its psychometric properties. The instrument developed to assess FH was initially made up of 20 items, of which 18 were negative and 2 were positive, assessed on a 5-point Likert scale (1-5). This scale was completed by 229 patients with type 1 diabetes. Additionally, a structured interview and a closed question called subjective fear of hypoglycemia were included as diagnostic criteria. A factor analysis employing the principal-components method and promax rotation was carried out, resulting in a new scale composed of 15 items. Three factors (fear, avoidance, and interference) were obtained and explained 58.27% of the variance. The scale showed good internal consistency (Cronbach's α = .891) and test-retest reliability (r = .908, p < .001), as well as adequate concurrent and predictive validity. The cutoff score that provided the highest overall sensitivity and specificity was set at 28 points. The Fear of Hypoglycemia 15-item scale (FH-15) demonstrated good reliability and validity. This study suggests that the new instrument may serve as a valuable measure of specific FH for use in research and clinical practice.  相似文献

The present study aimed to investigate the slow negative potential (termed Decision Preceding Negativity, DPN, from the family of the Readiness Potential) which precedes a willed risky decision. To this end, evoked potentials preceding and following an economic choice were measured in a sample of 16 male students during the Iowa Gambling Task modified for ERPs recording. Statistics revealed reduced positivity/relative greater negativity (marking relative activation) in right prefrontal sites and reduced negativity (indicating relative inhibition of DPN) in central clusters over left premotor cortex, 500 ms before picking from economically disadvantageous risky decks. Analyses of the potentials elicited by the economic outcome (wins vs. losses) showed the classical frontal negativity (N260) to the economic losses. Results are consistent with the view that an economically risky decision is preceded by a relative inhibition of the planned motor response together with the activation of emotion-related right frontal sites.  相似文献

Motor timing is essential for performing self-initiated movement sequences. Here, we investigated how sequence rhythm, or the timing for co-ordinating movements within a sequence, contributes to action preparation, compared with other processes occurring during sequence planning. First, we recorded the readiness potential (RP) in a condition of complex sequence rhythm and in condition of high demand on the timing for sequence initiation. We found that sequence rhythm and sequence initiation are independent processes, with sequence initiation contributing to early RP. Second, we compared the RP recorded in a condition of complex sequence rhythm and in a condition of complex sequence order, in which a complex combination of finger sub-movements had to be correctly ordered within a sequence. We found that sequence rhythm and sequence order share common processes occurring late RP. We suggest that the preparation for movement involves independent processes devoted to different aspects of motor timing and sequencing.  相似文献

This study explored the relationships between perceived sociocultural pressure to fulfill the thin beauty ideal, body distress, and the presence of eating disorder symptoms. Participants were 437 Chilean adolescent girls from Arica, northern Chile, aged 13-18. Results showed significant associations between perceived pressure from social agents to be thin and the presence of disrupted eating attitudes and behavior. The perceived influence of advertising, verbal messages and social situations related to eating and dieting emerged as the strongest predictors of eating disorders symptoms. Influence of advertising was also the strongest predictor of body image distress. Age differences emerged in perceived sociocultural pressure to be thin, with older participants reporting higher sociocultural pressure to fulfill the slender beauty ideal. This paper provides information about body distress and associated disturbances, a phenomenon which has seldom been studied in non-Western countries, but which has important health implications.  相似文献

Thinking ahead or not? Natural aging and anticipation during reading   总被引:1,自引:0,他引:1  
Despite growing evidence of young adults neurally pre-activating word features during sentence comprehension, less clear is the degree to which this generalizes to older adults. Using ERPs, we tested for linguistic prediction in younger and older readers by means of indefinite articles (a’s and an’s) preceding more and less probable noun continuations. Although both groups exhibited cloze probability-graded noun N400s, only the young showed significant article effects, indicating probabilistic sensitivity to the phonology of anticipated upcoming nouns. Additionally, both age groups exhibited prolonged increased frontal positivities to less probable nouns, although in older adults this effect was prominent only in a subset with high verbal fluency (VF). This ERP positivity to contextual constraint violations offers additional support for prediction in the young. For high VF older adults, the positivity may indicate they, too, engage in some form of linguistic pre-processing when implicitly cued, as may have occurred via the articles.  相似文献
