Internalization of the thin ideal has been thought to occur disproportionately among Caucasian, upper-class girls and women. The current research challenges this view by assessing thin-ideal internalization among low-income ethnic minority girls (N = 48). This research identifies differences between low-income ethnic minority adolescent girls who highly internalize the thin ideal (HI) and those who have lower internalization of thinness (LI). Results indicate that HI and LI groups do not differ based on ethnicity or weight categorization. Body satisfaction, competence, and perceived sociocultural pressure were analyzed as individual differences between HI versus LI participants. Those in the LI group have higher athletic competence and body satisfaction ratings for weight compared to the HI group. By identifying differences in thin-ideal internalization in this understudied population, factors that may protect someone from endorsing the thin ideal may be discovered. 相似文献

The authors present (a) an overview of the recent literature on social advocacy, (b) results of a deconstructive analysis of the philosophical and theoretical underpinnings of this movement, (c) a critical analysis of its role and function in the profession, and (d) a call to the profession. The deconstructive analysis revealed 2 major driving forces and 5 related trends; the critical analysis revealed 9 key areas of consideration. Implications and recommendations are presented. 相似文献

The authors examined the relationships between change-based and acceptance-based strategies for responding to negative internal
experience (thoughts and emotions) and levels of psychological symptoms and well-being. A large sample of undergraduate students
completed measures of their general frequency of experiencing negative affect and intrusive thoughts, their typical ways of
responding when these experiences occur, and their levels of psychological symptoms and well-being. Correlational analyses
showed that most of the identified ways of responding to negative internal experiences were significantly related to psychological
symptoms and well-being, even after accounting for the general frequency of experiencing unwanted thoughts and emotions. Regression
analyses suggested that change-based ways of responding add little or no incremental variance over acceptance-based strategies
in accounting for lower symptom levels and greater well-being. 相似文献

In many experiments, rats have evidenced extreme difficulty mastering alternation patterns. In three experiments, we explored rats’ ability to learn double alternation patterns and possible reasons behind their past difficulties with such patterns. In Experiment 1, rats learned single and double alternation patterns. In the second and third experiment, we explored the role of correction and interference from stimulus set size on rats’ learning of double alternation patterns. Our results showed that rats easily learned both single and double alternation patterns and that stimulus set size had no noticeable effect on learning double alternation patterns. Findings additionally evidenced that correction played an important role in rats’ learning double alternation patterns. 相似文献

The approximately 20-msec perceptual threshold for identifying order of onset for components of auditory stimuli has been considered both as a possible factor contributing to the perception of voicing contrasts in speech and as no more than a methodological artifact. In the present research, we investigate the identification of the temporal order of onset of spectral components in terms of the first of a sequence of thresholds for complex stimuli (modeled after consonant-vowel [CV] syllables) that vary in degree of onset. The results provide clear evidence that the difference limen (DL) for discriminating differences in onset time follows predictions based on a fixed perceptual threshold or limit at relatively short onset differences. Furthermore, the DL seems to be a function of context coding of stimulus information, with both the DL and absolute threshold probably reflecting limits on the effective perception and coding of the short-term stimulus spectrum. 相似文献

Recently, Andersen and Cyranowski (1994) presented a self-report measure of women's sexual self-schema, or cognitive view of the self regarding sexuality. In the current study, we investigated potential relationships between women's sexual self-schema and physical attractiveness, body size and shape, and body image. Young adult women ( N = 199) completed questionnaires and were weighed, measured, and rated for facial attractiveness. Results revealed that sexual self-schema was unrelated to body size or shape, general body dissatisfaction, history of teasing about weight, and degree of investment in personal appearance. Sexual self-schema scores significantly correlated with experimenter-rated facial attractiveness, self-rated facial and bodily attractiveness, and degree of social avoidance due to concerns over personal appearance, however. In a multiple regression analysis, only self-rated facial attractiveness and social avoidance were unique predictors. Results are discussed with regard to implications for the development of women's sexual self-schema and directions for future research. 相似文献

M. J. Lavin, B. Freise, and S. Coombes (Behavioral and Neural Biology, 1980, 28, 15–33) have shown that if two rats consume a flavored solution and one is poisoned, the unpoisoned partner will also exhibit a flavor aversion during a later preference test. Experiments 1 and 2 showed that a sufficient condition for obtaining this aversion is that the poisoned partner be present with the unpoisoned rat after it has consumed the flavored solution. It is not necessary that the poisoned partner be present when the flavored solution is consumed or indeed have had any exposure to the flavored solution. Experiment 3 showed that the unpoisoned partner can exhibit a flavor aversion when there is a temporal gap of as long as 6 hr between consumption of the flavored solution and exposure to the poisoned rat. 相似文献

Classical conditioning of the rabbit nictitating membrane (NM) response was adapted as a model system for simultaneous measurement of behavioral and neural responses in auditory signal detection. Animals were trained to a 36-dB spectral-level white-noise CS paired with a corneal airpuff US. The CS intensity was then reduced to threshold, using a modified staircase procedure, and responses on detect and nondetect trials were compared for the same stimulus intensities. At threshold, the behavioral NM response was dichotomous, being present on detect trials and completely absent on nondetect trials. In marked contrast, evoked neural unit activity to the CS recorded from the anteroventral cochlear nucleus was clearly present and identical on both detect and nondetect trials, suggesting that the detection “decision” is made more centrally than the cochlear nucleus. 相似文献
