The effect of the emotional quality of study-phase background music on subsequent recall for happy and sad facial expressions was investigated. Undergraduates (N = 48) viewed a series of line drawings depicting a happy or sad child in a variety of environments that were each accompanied by happy or sad music. Although memory for faces was very accurate, emotionally incongruent background music biased subsequent memory for facial expressions, increasing the likelihood that happy faces were recalled as sad when sad music was previously heard, and that sad faces were recalled as happy when happy music was previously heard. Overall, the results indicated that when recalling a scene, the emotional tone is set by an integration of stimulus features from several modalities.  相似文献

Following Karwoski, Odbert, and Osgood (Journal of General Psychology 26:199?C222, 1942), in the present article, cross-sensory correspondences are proposed to reflect the alignment of, and extensive bidirectional cross-activation among, dimensions of connotative meaning. The size?Cbrightness correspondence predicted on this basis (in which smaller is aligned with brighter) was confirmed in two ways. First, when participants explored three wooden balls of different size by touch alone and indicated how bright they thought each of them was, the smaller ball was judged to be brighter than the bigger ball. Second, when these two balls served as response keys in a speeded brightness-classification task, participants were quicker and more likely to be correct when confirming that a stimulus was bright (dark) when this required them to press the smaller (bigger) key, than when it required them to press the bigger (smaller) key. This congruity effect originated from interactions embedded in the later stages of information processing concerned with stimulus classification and response selection. These results, together with the observation that the cross-sensory features associated with smallness are the same as those associated with higher pitch sounds (i.e., both attributes are more active, brighter, faster, lighter in weight, quieter, sharper, and weaker than their opposites), support the suggestion that there exists a core set of cross-sensory correspondences that emerges whichever stimulus feature is used to probe it.  相似文献

The friendships of children displaying symptoms of attention-deficit/hyperactivity disorder (ADHD) have been understudied, particularly in comparison to the domain of peer rejection. This study tested whether friendship intimacy exchange buffers the prospective relation between ADHD symptoms and social problems 1 year later in a sample of children attending a community-based after-school program. Children (N?=?131; 53 % boys; 66 % African American) ranging from 5 to 13 years of age participated in this study. At baseline, children reported on friendship intimacy exchange with their identified best friend, and program staff rated children on ADHD symptoms and social problems. Staff ratings of children’s social problems were collected again 1 year later. Multiple regression analyses indicated that, after controlling for demographic variables and baseline social problems, friendship intimacy exchange significantly moderated the association between ADHD symptoms and social problems at the one-year follow-up. Specifically, the relation between ADHD and social problems was no longer significant for children reporting high levels of friendship intimacy exchange. This moderation was not further qualified by either child age or sex, although boys were more likely than girls to report low rates of friendship intimacy exchange. These findings indicate the importance of friendship intimacy for children displaying ADHD symptoms, who often experience significant peer problems. Friendship quality may be a promising target for prevention and intervention efforts in mitigating some of the long-term social problems associated with ADHD symptomatology, and future research is needed to extend these findings to other domains of friendship quality and clinical samples of children with ADHD.  相似文献

This qualitative study was nested within a trial of cognitive behaviour therapy (CBT) and supportive listening for patients with multiple sclerosis (MS). It aimed to enrich understanding of the changes made during therapy and to explore processes of change. In-depth interviews with 30 participants from the treatment trial were analysed inductively and five main themes were developed. The benefits that participants described experiencing as a result of the interventions were highly variable, idiosyncratic and often departed from outcomes measured within the trial. Tuning into and sharing one’s thoughts and feelings and learning specific strategies for living with MS appeared to be important processes for change, and participants identified the latter as particularly important for sustaining long-term benefits from therapy. Whether participants fully engaged with the interventions appeared to be related to their perceptions of being the right sort of candidate for the intervention, their expectations and motivations, the therapeutic relationship, adequate tailoring of the intervention, and practical issues. This study builds on previous research on factors and processes involved in adjustment to MS, the benefits of CBT for this population and highlights important issues to consider when developing psychosocial interventions for people with MS.  相似文献

Abstract

The present study examined coping flexibility and correlates of this style of approaching stressful situations. Two methods for assessing coping flexibility, the Flex (Schwartz and Daltroy, 1991) and a modification of the Ways of Coping Checklist (Folkman and Lazarus. 1980) were administered to 28 men and 32 women, who were also asked questions about their age, gender, style of impression management (self-monitoring and social desirability), and basic personality variables from the Multidimensional Personality Questionnaire (Tellegen. 1982). Subjects responded to four common scenarios described by a 2 (social/nonsocial) × 2 (minor/major) matrix. Gender differences were not found for the Flex, but men exhibited more flexibility than did women when determined by the WOC range score. Older subjects exhibited smaller ranges on both the Flex and the WOC, suggesting that they were less flexible in coping than were younger subjects. Correlations with the Self-Monitoring scale approached significance for the Flex and were significant for the WOC. Greater flexibility was associated with greater well-being and achievement and negatively correlated with stress reactions and alienation.  相似文献

Abstract

This study examined the dimensional structure and correlates of body satisfaction among middle-aged and older adult men (n = 471) and women (n = 383) who were participants in the Activity Counseling Trial. Correlates were grouped as (1) fitness parameters, (2) demographic characteristics, and (3) components of subjective well-being. Factor analyses demonstrated that body function and body appearance were independent components of satisfaction in this population. Body composition and cardiorespiratory fitness were directly related to satisfaction with body appearance; however, satisfaction with body function was most strongly related in expected directions to measures of subjective well-being. Age was positively related to both measures of body satisfaction, whereas data on race revealed that blacks were more satisfied with their body appearance and function than whites. The observed relationships for body satisfaction suggest that older adults may value body function more than body appearance. Furthermore, the associations of race and age with body satisfaction have important implications for intervention research.  相似文献

This study assessed the influence of five factors on respondents' judgments of whether two hypothetical actors, Tom and Lucy, would consider each other to be "sexual partners." The factors were: respondent's gender, actor's gender, type of act (vaginal, anal, or oral intercourse), frequency of act (once, several times), and actors' dating status (not dating, dated once, dated for three months). 223 undergraduates (mean age 22.2 - 2.2 years; 65% female) read 16 hypothetical heterosexual behavior scenarios featuring Tom and Lucy and judged whether Tom (Lucy) would consider Lucy (Tom) to be a "sexual partner." Respondents thought the actors would be more likely to consider each other sexual partners if they had engaged in vaginal or anal intercourse as opposed to oral sex; if they had more frequent sex; or if they were in a steady dating relationship. Researchers and health care professionals should take contextual/situational factors into account when they ask respondents about their sexual partners.  相似文献

A laboratory study investigated individual differences in the role of subjective goal difficulty as a mediating variable in a goal‐setting framework. A moderate or difficult anagram goal was assigned to participants based on individual task ability level. For individuals receiving a difficult goal 3 mediating relations and 1 moderator were found. For individuals receiving only moderately difficult goals, only 1 mediating relation was supported. Results are discussed with respect to goal‐setting theory.  相似文献

Although multitasking has been identified as an important competency for many jobs, standardized preemployment tests of multitasking are uncommon, and their validity beyond separate single-task assessments is unclear. To address this gap, this study compared the validity of a preemployment multitasking assessment (with math, memorization, and monitoring tasks presented concurrently) to an assessment in which the same constituent tasks were assessed separately. Among military pilot applicants, concurrent multitasking predicted both flying and academic performance, whereas serial single-task scores and their combination predicted only academic performance. Larger multitasking decrements (i.e., operationalized as the difference between single-task and multiple-task performance of the same constituent tasks) were associated with poorer flying performance. Results suggest the potential utility of multitasking assessments in selection for military jobs requiring competing, concurrent task demands.  相似文献

The present research assessed whether children with high and low scores on temperament traits differed in their ability to inhibit irrelevant task information in a lexical decision task. Children from 7 to 12 years old were classified based on temperament dimensions measured using a version of the Temperament in Middle Childhood Questionnaire. The participants were instructed to either attend to (and remember) or to ignore a masked prime word followed by a central probe target on which they made a lexical decision. The results revealed several notable outcomes. First of all, recognition memory was better for attended than ignored words, providing further evidence that attention instructions influenced the processing of the primes.

Secondly, although no negative priming effect was obtained in the “ignore” condition, 43% of children showed this effect. Thirdly, children scoring high on Inhibitory Control and Impulsivity showed ignored negative priming, whereas children scoring high on Inhibitory Control and low on Impulsivity ignored facilitation. Data are discussed within the framework of negative priming as a complex phenomenon that involves the interaction of different factors such as age, type of task, and certain temperament traits.  相似文献
