The tendency to hold and pursue excessively high standards for oneself and for others can interfere with academic achievement. Counsellors who work in university settings are often presented with students whose capabilities do not reflect their levels of achievement. This study reports on the evaluation of an eight-week group intervention designed to help university students shift from negative and often debilitating perfectionism to positive and enhancing perfectionism. The group treatment focused on changing attitudes, beliefs, feelings, and interpersonal interactions affected by perfectionism using combined cognitive-behavioral and interpersonal approaches. Standardized measures, including the Beck Depression Inventory (Beck et al., BDI-II manual. San Antonio: The Psychological Corporation, 1996), the Beck Anxiety Inventory (Beck and Steer, Beck Anxiety Inventory: Manual. San Antonio: The Psychological Corporation, 1993), and the Multidimensional Perfectionism Scale (Hewitt and Flett, Journal of Personality & Social Psychology, 60, 456–470, 1991a), provided data for pre- and post analysis of a treatment group (n = 30), and comparison groups of students attending group programs on career planning (n = 30) and attending psychology classes (n = 30). Results show that students participating in the treatment group significantly reduced their levels of depression, anxiety, and perfectionism in comparison to students who did not attend the treatment program. Implications of the findings suggest the importance of considering perfectionism on a continuum of negative and positive influences while helping students to address the intrapersonal and interpersonal dimensions of perfectionism.  相似文献

The ability to keep track of locations in a dynamic, multimodal environment is crucial for successful interactions with other people and objects. The authors investigated the existence and flexibility of spatial indexing in adults and 6-month-old infants by adapting an eye-tracking paradigm from D. C. Richardson and M. J. Spivey (2000). Multimodal events were presented in specific locations, and eye movements were measured when the auditory portion of the stimulus was presented without its visual counterpart. Experiment 1 showed that adults spatially index auditory information even when the original associated locations move. Experiments 2 and 3 showed that infants are capable of both binding multimodal events to locations and tracking those locations when they move.  相似文献

Rabbits were given reinforced training of the nictitating membrane (NM) response using separate conditioned stimuli (CSs), which were a tone, light, and/or tactile vibration. Then, two CSs were compounded and given further pairings with the unconditioned stimulus (US). Evidence of both overexpectation and summation effects appeared. That is, responding to the individual CSs declined despite their continued pairing with the US on compound trials (overexpectation), and responding on the compound trials was greater than responding to the individual CSs (summation). The response loss appeared regardless of the testing regime, that is, whether the test presentations of the individual CSs were themselves reinforced (Experiment 2), not reinforced (Experiment 1), or deferred until the end of compound training (Experiment 2). The results are discussed with respect to the roles of excitatory versus inhibitory processes, elemental versus configural processes, and the possible roles of cerebellar and hippocampal pathways.  相似文献

Substantial research has compared obese and nonobese persons on body image and psychosocial adjustment. While differences in body satisfaction are often observed, the literature is less clear on other dimensions. Extant differences are typically thought to result from the social stigmatization and maltreatment experienced by obese persons, especially females. The present study of 165 women compared three cohorts who were currently overweight, never overweight, or formerly overweight. Relative to never-overweight women, currently overweight women reported more body dissatisfaction/distress, overweight preoccupation, and dysfunctional appearance investment, as well as more binge eating, lower social self-esteem, and less satisfaction with life. Consistent with the “phantom fat” phenomenon, formerly overweight women were comparable to currently overweight women but worse than never-overweight women on overweight preoccupation and dysfunctional appearance investment. Correlations confirmed that, among overweight but not formerly overweight women, more frequent stigmatizing experiences during childhood, adolescence, and adulthood were significantly associated with currently poorer body image and psychosocial functioning. Scientific and clinical implications of the findings are discussed.  相似文献

In the local population of kea in Mount Cook Village, New Zealand, some keas open the lids of rubbish bins with their bill to obtain food scraps within. We investigated the extent to which this innovation has spread in the local population, and what factors limit the acquisition of bin opening. Only five males of 36 individually recognised birds were observed to have performed successful bin opening. With one exception there were always other keas present, watching successful bin opening. Seventeen additional individuals were seen to have benefitted from lid opening. Their foraging success was less than that of the bin openers. Social status of bin openers did not differ from scrounging males. Among the individuals that were regularly seen at the site of the bins but were not successful in bin opening, social status and the ratio of feeding directly from open bins correlated with the amount of opening attempts. We conclude that scrounging facilitated certain behavioural aspects of bin opening rather than inhibiting them. The fact that only 9% of opening attempts were successful, and the long period of time required to increase efficiency in lid opening shows that mainly individual experience, and to a lesser extent insight and social learning, play key roles in acquisition of the opening technique. The results indicate that the spread of innovative solutions of challenging mechanical problems in animals may be restricted to only a few individuals.  相似文献

Ethical considerations for working with runaway and homeless youth in research and treatment settings are presented. Issues of parents' and adolescents' consent for research and treatment are discussed, with particular attention given to the lack of explicit guidelines for working with abused and neglected youth. The principles of beneficence and justice are discussed as they apply to intervening with a high-risk, multiproblem population. The authors offer a rationale for allowing adolescents to self-consent to research and treatment. They argue that in many circumstances, requiring parental consent may not be in the youth's best interest and may preclude his or her participation in treatment and research programs.  相似文献

The present article includes separate meta-analyses showing that self-concordance and implementation intentions are significantly positively associated with goal progress. Study 1 confirmed the positive relations of both self-concordance and implementation intentions to weekend goal progress. Study 2 confirmed the positive relation of self-concordance with monthly progress on New Year's resolutions but failed to find a direct benefit for implementation intentions. Both studies, however, obtained a significant interaction effect indicating that goal self-concordance and implementation intentions combined synergistically to facilitate goal progress. The article also reports a meta-analysis and results from the 2 studies that demonstrated that goal progress was associated with improved affect over time.  相似文献

The extent to which decision-making processes are constrained in animals with small brains is poorly understood. Arthropods have brains much smaller and simpler than those of birds and mammals. This raises questions concerning limitations on how intricate the decision-making processes might be in arthropods. At Los Ba?os in the Philippines, Scytodes pallidus is a spitting spider that specialises in preying on jumping spiders, and Portia labiata is a jumping spider that preys on S. pallidus. Scytodid spit comes from the mouth, and egg-carrying females are less dangerous than eggless scytodids because the female uses her chelicerae to hold her eggs. Held eggs block her mouth, and she has to release them before she can spit. The Los Ba?os P. labiata sometimes adjusts its tactics depending on whether the scytodid encountered is carrying eggs or not. When pursuing eggless scytodids, the Los Ba?os P. labiata usually takes detour routes that enable it to close in from behind (away from the scytodid's line of fire). However, when pursuing egg-carrying scytodids, the Los Ba?os P. labiata sometimes takes faster direct routes to reach these safer prey. The Los Ba?os P. labiata apparently makes risk-related adjustments specific to whether scytodids are carrying eggs, but P. labiata from Sagada in the Philippines (allopatric to Scytodes) fails to make comparable risk-related adjustments.  相似文献

Many words have more than one meaning, and these meanings vary in their degree of relatedness. In the present experiment, we examined whether this degree of relatedness is influenced by whether or not the two meanings share a translation in a bilingual’s other language. Native English speakers with Spanish as a second language (i.e., English-Spanish bilinguals) and native Spanish speakers with English as a second language (i.e., Spanish-English bilinguals) were presented with pairs of phrases instantiating different senses of ambiguous English words (e.g., dinner dateexpiration date) and were asked to decide whether the two senses were related in meaning. Critically, for some pairs of phrases, a single Spanish translation encompassed both meanings of the ambiguous word (joint-translation condition; e.g., mercado in Spanish refers to both a flea market and the housing market), but for others, each sense corresponded to a different Spanish translation (split-translation condition; e.g., cita in Spanish refers to a dinner date, but fecha refers to an expiration date). The proportions of “yes” (related) responses revealed that, relative to monolingual English speakers, Spanish–English bilinguals consider joint-translation senses to be less related than split-translation senses. These findings exemplify semantic cross-language influences from a first to a second language and reveal the semantic structure of the bilingual lexicon.  相似文献

This study investigated beginning adult second language (L2) learners' sensitivity to L2 morphosyntactic violations as a function of cross-language similarity. Online sensitivity was indexed by self-paced reading times at: (1) the critical word at which the violation could first be detected, (2) the post-critical word, and (3) the sentence-final word. In conditions in which morphosyntactic marking systems were similar or different in L1 and L2, reading times on the critical word were slower when it cued a violation than when it did not; however, this sensitivity was not apparent in a construction unique to L2. Slower reading times to violations spilled over onto the post-critical word. Cross-language similarity also influenced sentence-final word reading times. Despite this online sensitivity, post-sentence grammaticality judgements were generally poor. However, these judgements were influenced by morphosyntactic markings on words after the critical word, suggesting that learners can make use of this information.  相似文献
