Students differ in how they cope with and manage stress associated with university life. This study investigates associations between adult attachment and coping strategies for exam-related stress. Fifty-seven students at a university in the north of England completed online questionnaires to assess attachment anxiety and avoidance, helpful and unhelpful coping strategies, and positive and negative affect. We found that students who were more avoidant in their attachment relationships were less likely to report using helpful problem-focused and emotion-focused strategies to cope with their exams. We also found that students who were more anxious in their attachment relationships reported using more dysfunctional coping strategies. We discuss the implications of the findings for university pastoral care and academic support systems.  相似文献

Girls in the United States are increasingly confronted with a sexualized culture, including sexualized clothing made especially for pre-teen girls. Previous research has shown that when adult women are portrayed as sexualized they are seen as less competent. In the present study we depicted a pre-teen girl in sexualized clothing to determine if similar effects would occur as have been found with depictions of adult women. One hundred sixty two male and female students from a small liberal arts college in the Midwestern U.S. looked at one of three images of a fifth-grade girl (obtained from an internet advertisement and manipulated through computer software) who was presented in either childlike clothing, somewhat sexualized clothing, or definitely sexualized clothing. Level of accomplishment was also manipulated so that the girl was described as either average or above average in accomplishment. Participants then rated the girl on ten different traits. The clothing and accomplishment manipulations significantly affected ratings of the girl’s masculine-stereotyped traits such that the girl who was portrayed as more sexualized and less accomplished was seen as the least intelligent, competent, determined, and capable. In addition, the sexualized girl was seen as perhaps “responsible” for her sexualized clothing in that she was rated relatively low in self-respect and morality. Possible implications of the sexualization of girls are discussed.  相似文献

Three experiments explored online recognition in a nonspeech domain, using a novel experimental paradigm. Adults learned to associate abstract shapes with particular melodies, and at test they identified a played melody's associated shape. To implicitly measure recognition, visual fixations to the associated shape versus a distractor shape were measured as the melody played. Degree of similarity between associated melodies was varied to assess what types of pitch information adults use in recognition. Fixation and error data suggest that adults naturally recognize music, like language, incrementally, computing matches to representations before melody offset, despite the fact that music, unlike language, provides no pressure to execute recognition rapidly. Further, adults use both absolute and relative pitch information in recognition. The implicit nature of the dependent measure should permit use with a range of populations to evaluate postulated developmental and evolutionary changes in pitch encoding.  相似文献

The effect of concurrent visual feedback (CVF) on continuous aiming movements was investigated in the preferred hand of participants of college age (ns = 12 men, 8 women). Participants made continuous rapid reversal movements with a lightweight lever in the sagittal plane. Participants attempted to reach a short target (20 degrees) and a long target (60 degrees) in separate constant practice conditions, but alternated between the two targets in a variable practice condition. Four blocks of practice trials were provided in each condition, with 40 movements made in each. CVF of the position-time trace was provided for the first 20 movements of each block, but was removed for the remaining 20 movements in each block. Movements were more accurate and consistent during constant practice compared to variable practice where the short target was overshot and the long target was undershot. CVF reduced errors in all conditions, compared to movements without CVF, particularly for the short target during variable practice. The results suggest that the interference generated by alternating targets can be modulated by providing visual feedback, but once the visual feedback was removed, errors increased markedly.  相似文献

In this paper, we review the recent literature on the debate over the value of self-enhancement. Past studies fall into two distinct sets, each in the context of a different research tradition. The componential approach to self-enhancement integrates these two divergent perspectives and takes seriously the interplay of self-perception and interpersonal perception. Instead of global indices, the componential approach identifies specific components of person perception. By partitioning the components in self-perception, the componential approach allows for better understanding of the dynamic interactive effects of self-enhancement bias and other components in self-perception on adjustment. We conclude the paper by discussing the emerging attempts to advance a componential approach to examine self-perception in terms of components and outcomes.  相似文献

Communicators' tuning of a message about a social target to their audience's evaluation can shape their representation of the target. This audience‐tuning effect has been demonstrated with ambiguous text passages as input material. We examined whether the effect also occurs when communicators learn about the target's behaviours from visual (nonverbal) input material. In Experiment 1, participants watched a soundless video depicting ambiguous behaviours of a target, described the video to an audience who liked (vs. disliked) the target, and subsequently recalled the video. Both message and recall were biased towards the audience's judgement. In Experiment 2, the video depicted a forensically relevant event, specifically ambiguous behaviours of two persons involved in a bar brawl. Participants tuned their event retellings to their audience's responsibility judgement and remembered the event accordingly. In both experiments, the effect of the audience's judgement on recall was statistically mediated by the extent to which the message was tuned to the audience. The more participants experienced a shared reality with their audience the stronger was the message‐recall correlation (Experiment 2). We conclude that the audience‐tuning effect for visually perceived information depends on the communicators' creation of a shared reality with their audience.

Conflicting findings exist regarding (1) whether anxiety sensitivity (AS) is a construct distinct from anxiety in children and (2) the specific nature of the role of AS in child anxiety. This study uses meta-analytic techniques to (1) determine whether youth (ages 6–18 years) have been reported to experience AS, (2) examine whether AS differentiates anxiety disordered youth from youth without diagnoses, and (3) ascertain whether AS distinguishes youth with panic disorder from those with other anxiety disorders. The weighted mean effect size analyses included 15 studies and 6,579 participants. Results suggested positive correlational relationships between AS and anxiety for children (r = 0.26) and adolescents (r = 0.36) and higher levels of AS for anxiety disordered youth than non-clinical youth (d = 0.64). Findings tentatively suggested higher levels of AS for youth with panic disorder than youth diagnosed with other anxiety disorders. Implications and future directions in the research of child AS are discussed.  相似文献

Various studies have found that viewing physical or relational aggression in the media can impact subsequent engagement in aggressive behavior. However, this has rarely been examined in the context of relationships. Accordingly, the aim of this study was to examine the connection between viewing various types of aggression in the media and perpetration of aggression against a romantic partner. A total of 369 young adults completed a variety of questionnaires asking for their perpetration of various forms of relationship aggression. Participants' exposure to both physical and relational aggression in the media was also assessed. As a whole, we found a relationship between viewing aggression in the media and perpetration of aggression; however, this depended on the sex of the participant and the type of aggression measured. Specifically, exposure to physical violence in the media was related to engagement in physical aggression against their partner only for men. However, exposure to relational aggression in the media was related to romantic relational aggression for both men and women.  相似文献

To study the temporal dynamics and capacity-limits of attentional selection and encoding, researchers often employ the attentional blink (AB) phenomenon: subjects' impaired ability to report the second of two targets in a rapid serial visual presentation (RSVP) stream that appear within 200-500 ms of one another. The AB has now been the subject of hundreds of scientific investigations, and a variety of different dual-target RSVP paradigms have been employed to study this failure of consciousness. The three most common are those where targets are defined categorically from distractors; those where target definition is based on featural information; and those where there is a set switch between T1 and T2, with the first target typically being featurally defined and T2 requiring a detection or discrimination judgment (probe task). An almost universally held assumption across all AB theories is that these three tasks measure the same deficit; however here, using an individual differences approach, we demonstrate that AB magnitude is only related across categorical and featural tasks. Thus, these paradigms appear to reflect a distinct cognitive limitation from that observed under set-switch conditions.  相似文献

Prior knowledge shapes our experiences, but which prior knowledge shapes which experiences? This question is addressed in the domain of music perception. Three experiments were used to determine whether listeners activate specific musical memories during music listening. Each experiment provided listeners with one of two musical contexts that was presented simultaneously with a melody. After a listener was familiarized with melodies embedded in contexts, the listener heard melodies in isolation and judged the fit of a final harmonic or metrical probe event. The probe event matched either the familiar (but absent) context or an unfamiliar context. For both harmonic (Experiments 1 and 3) and metrical (Experiment 2) information, exposure to context shifted listeners' preferences toward a probe matching the context that they had been familiarized with. This suggests that listeners rapidly form specific musical memories without explicit instruction, which are then activated during music listening. These data pose an interesting challenge for models of music perception which implicitly assume that the listener's knowledge base is predominantly schematic or abstract.  相似文献
