In adults, the ability to apply semantic grouping strategies has been found to depend on working memory. To investigate this relation in children, two sort-recall tasks (one without and one with a grouping instruction) were administered to 6–12-year-olds. The role of working memory was examined by means of mediation analyses and by assessing whether children who successfully used the semantic grouping strategy had higher working memory capacity than did children who did not show such strategy use. Only children aged 8–12 were able to successfully use semantic grouping strategies (and 8–9-year-olds only after instruction), while strategy use was absent in 6–7-year-olds. Both types of analysis involving working memory suggested that, also in children, working memory (and not short-term memory) mediates the development of successful use of the semantic grouping strategy during both encoding and retrieval.  相似文献

Abstract

HIV/AIDS knowledge, age at onset of sexual activity, perceptions of personal risk and peer norms were explored as correlates for risky sexual behaviors among college students. Ninety-nine male and 185 female college students completed a 66-item questionnaire. A majority reported being sexually active with most in mutually monogamous relationships or not currently in a sexual relationship. Multiple regression correlation analyses showed knowledge about HIV/AIDS to be very high but that this knowledge did not independently relate to the extent of risky behaviors. Perceptions of risk were positively related to number of partners and single-time partners but not condom usage. In contrast to previous studies, perceived peer norms did not independently relate to behaviors. Instead, age at first intercourse was found to have substantial overlap with current perceptions, attitudes, and likelihood for engaging in risky behaviors. The necessity for including previous behaviors in analyses of the impact of attitudes and perceived norms on behavioral intentions is discussed.  相似文献

A condom use promotion leaflet was designed for use with older teenagers in schools. The text targeted a series of cognitive and behavioural antecedents of condom use identified in the literature. Given previous evidence that motivational incentives can enhance the effectiveness of health promotion leaflets, the leaflet was presented in conjunction with a quiz and prize draw. Students were randomly assigned to either the intervention condition or a (no leaflet or incentive) control condition. Measures were taken immediately, pre-intervention and 4 weeks later from 404 students. The 20-min intervention successfully promoted six of the eight measured cognitions, namely (1) attitude towards using condoms with a new partner (2) attitude towards using condoms with a steady partner (3) normative beliefs in relation to preparatory actions (4) self-efficacy in relation to both preparatory actions and (5) condom use (6) intention to use condoms, as well as three measured preparatory actions, that is, purchasing condoms, carrying condoms and discussing condom use. The intervention did not increase condom use with steady or new partners but power to test intervention impact on condom use was curtailed.  相似文献

Abstract

This study examined the importance of the nature of the relationship between sexual partners in predicting types of sexual practices for 293 gay and bisexual men. Demographics, personal beliefs, substance use, and variables from the health belief model, theory of self-efficacy, and theory of reasoned action were used to predict sexual behaviors. Sexual practices varied by type of partner relationship and duration, with a higher probability of risky behaviors occurring with primary partners than with non-primary partners; relationship status also moderated the effects of safer sex partner norms and denial on sexual risk-taking. In addition, men who were younger, had less education, and used alcohol or drugs prior to sex engaged in higher risk behaviors. This study indicates that a more comprehensive assessment of dimensions of partner relationship will lead to greater understanding of sexual risk-taking.  相似文献

A number of models of behaviour have been applied to contraception use including subjective expected utility theory and social cognition models. Whilst correlates of contraception use have been identified, the limitations of these models include their failure to consider either contextual factors or changes in contraception use over time. Researchers have called for integrated and dynamic models of contraception use, which can be related to the changing contraception use of individual women and can also be readily operationalised to explore within and between subject differences in contraception use. The present study therefore used a qualitative methodology to explore women's contraceptive histories and to enable women to define the issues from their perspectives, resulting in a model of contraception use that is firmly located within the context of their own lives and allows an investigation of the factors and processes involved in changes in contraception use/non-use over time. This model conceptualises the predictors of contraception use in terms of the meaning and importance of a range of social goals, perceptions of vulnerability and constraints on or facilitators of contraception. Further the dynamic nature of these factors is described and it is illustrated how these core components vary over time according to situation, experience, and new information. The paper outlines the relevance of the findings for different models of decision-making processes and highlights the way that the model addresses the limitations of previous approaches.  相似文献

Objective: This study investigated the role of coping plans and the use of selection, optimisation and compensation (SOC) strategies within an experimental evaluation of a 26-week physical exercise intervention.

Methods: Older women (N?=?86, M age?=?73.7 years) were randomly assigned to a telephone-assisted or a self-administered coping planning intervention after 6 weeks’ participation in an exercise programme. The number of different coping plans formulated, exercise-specific SOC strategy use and their interaction were used to predict objectively measured long-term adherence to the intervention.

Results: The number of coping plans formulated (β?=?0.28) and goal-pursuit strategies reported (sum score of optimisation and compensation strategies, β?=?0.39) predicted adherence to the exercise programme over 20 weeks. The predictive strength of coping plans increased with decreasing numbers of goal-pursuit strategies (β?=??0.21). Women supported via telephone reported significantly more coping plans than did women in the self-administered coping planning group, F(1,80)?=?9.47, p?=?0.003.

Conclusion: Coping plans have a buffering effect on adherence levels when use of SOC strategies is low. Older women's adherence to physical activities may be improved if they are given direct support in generating coping plans involving strategies of selection, optimisation and compensation.  相似文献

Individuals decide to use healthcare when the expected benefits outweigh the perceived costs. One of these cost factors in this decision can be stigma. So far, it has not been researched how former soldiers of the German Armed Forces with a service-induced mental illness perceive stigma and how it influences their healthcare use. As stigma is shaped by the socio-cultural context, the setting of the potential healthcare use must be considered. Narrative interviews were conducted with 33 former soldiers with mental health problems. The data were analyzed using a thematic analysis approach, in which codes were formed and emerging themes were systemized. The relationship between stigma and healthcare use was analyzed. Occupational discrimination and social exclusion were experienced in both in the military and civilian context, but stigma functioned differently in each context. In the military context, former soldiers’ self-stigma of mentally ill individuals being weak was in stark contrast to their internalized military standards. This contrast let them avoid disclosure and subsequent healthcare use. In civilian context, the participants perceived 2 different stigma costs: mental illness stigma and former soldier stigma (i.e., stigmatization because of their military past). Both were perceived as barriers to healthcare use. A model, illustrating these different stigma costs in the different contexts, was developed. Further research on the link between stigma and healthcare use of this group is urgently needed.  相似文献

The social skills model of generalized problematic internet use predicts that individuals who perceive themselves as having low social competencies are at risk to develop a preference for online social interactions (POSI), which, in turn, might lead to compulsive use of Internet communication services. The present study aims to investigate if self-reported emotional intelligence (EI)—interpersonal and intrapersonal abilities—has an effect on POSI levels, and if this effect is mediated by the subjective importance attached to the major controllability (RC) and reduced non-verbal cues (RNVC) of computer mediated communication. 192 high schools and college students were recruited. Results from structural equation modeling show that Intrapersonal EI predicts both RC and RNVC, which, in turn, predicts the level of POSI. A partial mediation effect was found. On the other hand, Interpersonal EI is significantly associated with POSI, but this association cannot be explained by RC and RNVC. Its effect on POSI seems to be either direct or explained by variables not considered in the present study.  相似文献

We examined differences in sexual behaviors among White, Black, and Hispanic adolescent females exposed to dating or sexual violence (DSV) using the 2009 Youth Risk Behavior Survey. We also examined the interaction effect of exposure to DSV and race or ethnicity on sexual behaviors. Sexual behaviors were significantly associated with both race or ethnicity and DSV; DSV was a stronger predictor of sexual behaviors than race or ethnicity; and the effect of DSV on condom use was more pronounced among Hispanic adolescents, whereas the effect of DSV on birth control use was more pronounced among both Black and Hispanic adolescents. Adolescent health programs should simultaneously address DSV and sexual risk reduction, with particular emphasis on birth control and condom use among ethnic minority populations.  相似文献

When travelling through a new environment people can and do make very quick judgements about the local conditions. This paper explores the idea that such judgements are affected by the travel mode they use. We hypothesise that drivers generate a more superficial impression of the things they observe than those who walk because they are exposed to less information. This prediction is based on social psychological research that demonstrates that information that becomes available in “thin slices” affects superficial judgements. A survey study (n = 644) demonstrated that perceptions of a less affluent area are indeed negatively related to more driving and positively related to more walking, but only for those who do not live there. Perceptions of a neighbouring affluent area are positively related to more driving. Two experimental studies (n = 245 and n = 91) demonstrated that explicit (but not implicit) attitudes towards a group of young people in an ambiguous social situation are more negative when they are viewed from the perspective of a car user in particular in relation to a pedestrian perspective. These findings suggest that mode use may affect communities by influencing social judgements.  相似文献
