This study tests the hypothesis that cultural differences in group orientation predict an interaction between the student variable—ethnicity—and a learning context variable—reward structure—on math performance after group learning. One hundred and thirty-two African-American and European-American female and male fourth and fifth grade students studied math estimation in one of three group learning contexts. The learning contexts operationalized were: intergroup competitive, interpersonally competitive, and communal-no reward. ANCOVA confirmed a predicted interaction of ethnicity with learning context on post study session performance. Although there was no difference overall, African-American and European-American students performed best in the aggregate in different contexts. Independent ratings of students' group-positive behaviors mirrored the two-way interaction between learning context and ethnicity. The findings suggest that important student variables interact with the variable elements of group learning and should be studied in greater detail. They also support Boykin's (1994) contention that the cultural context of learning is a critical mediator of children's achievement. 相似文献

The majority of research on self‐monitoring has focused on the positive aspects of this personality trait. The goal of the present research was to shed some light on the potential negative side of self‐monitoring and resulting consequences in two independent studies. Study 1 demonstrated that, in addition to being higher on Extraversion, high self‐monitors are also more likely to be low on Honesty‐Humility, which is characterized by a tendency to be dishonest and driven by self‐gain. Study 2 was designed to investigate the consequences of this dishonest side of self‐monitoring using two previously unexamined outcomes: moral disengagement and unethical business decision making. Results showed that high self‐monitors are more likely to engage in unethical business decision making and that this relationship is mediated by the propensity to engage in moral disengagement. In addition, these negative effects of self‐monitoring were found to be due to its low Honesty‐Humility aspect, rather than its high Extraversion side. Further investigation showed similar effects for the Other‐Directedness and Acting (but not Extraversion) self‐monitoring subscales. These findings provide valuable insight into previously unexamined negative consequences of self‐monitoring and suggest important directions for future research on self‐monitoring.

In this article, ethical issues related to the treatment of families with a member with mental retardation are discussed. The history of psychotherapeutically treating the community with mental retardation and accompanying concerns, such as dual diagnosis and diagnostic overshadowing, are discussed. Ethical considerations of the informed consent and assent process are discussed and applied to more modern areas of confidentiality, treatment goals, and individual sexuality. Marriage and family therapists are encouraged to bring clarity and balance to the process of informed consent and assent when working systemically with the population with mental retardation and their families. 相似文献

ABSTRACT Knowledge of cross-informant rating concordance is critical for the assessment of child and adolescent problems in clinical and research settings. We explored parent-youth rating concordance for hair pulling variables, functional impairment, and anxiety symptoms in a sample of child and adolescent hair pullers (n = 133) satisfying conservative diagnostic criteria for trichotillomania (TTM). Whole group analyses reveal significant parent-youth agreement on all study variables. Split group analyses, however, reveal superior parent-youth concordance for the adolescent (15–17 years old) versus younger (10–12 years old) hair pullers for awareness of hair pulling and anxiety scale scores. These results highlight the need for both parent and youth ratings when assessing younger children with TTM. 相似文献

Current models of verbal short‐term memory (STM) propose various mechanisms for serial order. These include a gradient of activation over items, associations between items, and associations between items and their positions relative to the start or end of a sequence. We compared models using a variant of Hebb's procedure in which immediate serial recall of a sequence improves if the sequence is presented more than once. However, instead of repeating a complete sequence, we repeated different aspects of serial order information common to training lists and a subsequent test list. In Experiment 1, training lists repeated all the item–item pairings in the test list, with or without the position–item pairings in the test list. Substantial learning relative to a control condition was observed only when training lists repeated item–item pairs with position–item pairs, and position was defined relative to the start rather than end of a sequence. Experiment 2 attempted to analyse the basis of this learning effect further by repeating fragments of the test list during training, where fragments consisted of either isolated position–item pairings or clusters of both position–item and item–item pairings. Repetition of sequence fragments led to only weak learning effects. However, where learning was observed it was for specific position–item pairings. We conclude that positional cues play an important role in the coding of serial order in memory but that the information required to learn a sequence goes beyond position–item associations. We suggest that whereas STM for a novel sequence is based on positional cues, learning a sequence involves the development of some additional representation of the sequence as a whole. 相似文献

Bullying and mobbing are occupational safety hazards pervasive in developed and developing countries. Our study aim was to determine whether bullying and mobbing caused poor health for a victim and a witness from the same workplace in western Canada. Longitudinal semistructured interviews were conducted in 2007 and 2008 with both parties. The interviews were transcribed, analyzed, and arranged into arrays using chronological ordering and time sequencing. The victim felt targeted because she represented a threat to the bully, with victim and witness experiencing negative health outcomes. The authors suggest that wellness programs should place greater emphasis on mental health promotion to discourage workplace bullying. 相似文献

This paper reviews three theoretical models of how prejudice affects the self-esteem of its targets. The stimulus-response model assumes that prejudice has a direct, negative effect on self-esteem. The stimulus-perception-response model recognises that perceptions of prejudice may not directly mirror experiences with prejudice, but predicts that the subjective perception of being a target of prejudice has a direct, negative effect on self-esteem. Both of these models are found to be inadequate. We propose a third, transactional model, which assumes that individuals do not respond in uniform way to being the target of prejudice. Rather, this model contends that self-esteem and emotional responses to prejudice are determined by cognitive appraisals of prejudicial events and coping strategies used in response to these events; these processes, in turn, are shaped by personal, situational, and structural factors. Experiments are presented showing that self-esteem in response to perceived prejudice is moderated by presence or absence of threats to personal identity, clarity of prejudices cues in the situation, ingroup identification, dispositional optimism, endorsement of legitimising ideologies, and group status. We argue that a transactional model of responses to prejudice emphasises sources of resistance as well as vulnerability among targets of prejudice. 相似文献

In the present study, we examined the psychometric properties of the Skin Picking Impact Scale (SPIS; Keuthen, Deckersbach, Wilhelm et al., 2001), a 10 item self‐report questionnaire designed to assess the psychosocial impact of skin picking disorder (SPD). Participants were 650 individuals who met criteria for SPD in an online survey. Exploratory and confirmatory factor analyses demonstrated a unitary factor structure with high internal consistency (α = 0.94). Consequently, we constructed an abbreviated 4‐item version that retained good internal consistency (α = 0.87) and a robust factor structure. Both the short and the full versions demonstrated discriminant and convergent/concurrent validity. In conclusion, the findings indicate that both versions are psychometrically sound measures of SPD related psychosocial impact; however, some potential limitations of the full scale are discussed. 相似文献

Unconscious visual stimuli can be processed by human observers and influence their behaviour. A striking example is a phenomenon known as “free-choice priming,” where masked “prime” stimuli—of which participants are unaware—modulate which of two response alternatives they are likely to choose. Recent efforts to uncover the mechanisms underlying this intriguing effect have revealed that free-choice priming can emerge even in the absence of automatized stimulus-response (S-R) associations between masked primes and specific motor responses, indicating that free choices can be influenced by a masked prime’s meaning (Ocampo, 2015). It remains unknown, however, whether masked primes bias response selections because they are implicitly classified according to task instructions, or because spreading activation occurs within the prime's semantic network. To adjudicate between these two possibilities, participants in the present experiment categorised targets as either animals or people and selected which of two response alternatives they wanted to make following presentation of a free-choice target. Crucially, while implicit classifications could proceed during processing of both animal and person masked primes, only animal primes could trigger spreading activation within their semantic network. This manipulation modulated free-choice priming; only masked animal primes influenced response selections to free-choice targets. This result indicates that an automatic spreading activation mechanism might underlie a masked prime’s ability to influence free-choice responses. 相似文献

Several studies have found that perceived social support plays a crucial role in the psychological and physical wellbeing of young people. A number of instruments measuring perceived social support have been developed and validated, including the Perceived Social Support from Family and Friends subscales. The psychometric properties of the Perceived Social Support from Family and Friends subscales have been demonstrated in a range of samples, although not in Ghana. The purpose of this study is to investigate the psychometric properties of the Perceived Social Support from Family and Friends subscales in Ghanaian adolescents using data from a school-based survey (N?=?770; 14–21 years). Participants completed a self-report questionnaire containing the Perceived Social Support from Family and Friends subscales, the Adolescent Stress Questionnaire, and the 12-item General Health Questionnaire. An exploratory factor analysis in addition to simultaneous confirmatory factor analyses with structural equation modelling were performed to evaluate the factor structure and factorial validity of the subscales along with Cronbach’s α and intercorrelations. Three factors and two factors were extracted for the Friends and Family subscales respectively. While the unidimensional model of the friends subscale had a better fit with the data than the three-factor model, the two-factor model of the family subscale had a better fit than the unidimensional model, even though the unidimensional models of both subscales produced higher internal consistency coefficients. With respect to construct validity, the family subscale demonstrated some evidence of convergent and discriminant validity, but the friends subscale demonstrated some evidence of only discriminant validity, in terms of the association between social support and common mental illness and perceived stress. It appears that the Perceived Social Support subscales are useful instruments for assessing social support from family and friends and could therefore be used to further our understanding about the role of social support in stressful life events and psychological functioning of Ghanaian adolescents, although further research is required for the friends subscale. 相似文献
