There is much evidence that parents' perceptions of children's competence affect the development of children's academic functioning. In the current research, the possibility that this is moderated by parents' theories about the stability of competence was examined. In a 2-wave, 1-year study of 126 children (9 to 12 years old) and their mothers, children's academic functioning (i.e., grades, perceptions of competence, attributions for performance, and mastery orientation) and affective functioning (i.e., self-esteem and depressive symptoms) were examined. Among mothers with relatively high entity theories, their perceptions acted as self-fulfilling prophecies foreshadowing children's academic and affective functioning over time. However, among mothers with relatively low entity theories, mothers' perceptions did not predict children's academic and affective functioning.

This study tested the efficacy of implementation intentions in the context of drivers' speeding behavior. Participants (N = 300) completed self-report measures of goal intention and behavior, and they were randomly assigned to an experimental condition, which required them to specify an implementation intention, or a control condition. One month postbaseline, self-reported compliance with speed limits significantly increased for experimental participants but not for control participants. The effects of specifying an implementation intention on behavior increased with the strength of drivers' goal intentions. Finally, analysis of participants' implementation intentions revealed that specifying more behavioral strategies increased the frequency with which participants reported complying with the speed limit. Implications of the findings are discussed in relation to enhancing road safety interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

现代包装设计与消费心理关系   总被引:6,自引:1,他引:6  
陈志权 《包装工程》2006,27(1):246-247
探讨包装在商品的流通中,消费心理及设计语言与消费者之间如何信息传递.包装设计最主要的功能是保护商品,其次是美化商品和传达信息,除此之外还应运用心理学的范畴,着重探讨研究设计形式因素和分析消费者的各种心理因素.只有这样才能准确地摸索到包装设计与消费者心理活动的规律,从而提高包装设计的效果,促使消费者产生购买商品的欲望与行动.  相似文献

This article takes a psychoanalytic approach to questions usually considered to be matters of the family court system. The psychological effects of high-conflict divorce on children are well known, but what motivates their parents is less understood. Pathological narcissism, pathological envy, disavowal, and a perverse attitude toward reality can produce unending conflicts over visitation and custody. Fighting over seemingly insignificant matters can manage aggression and ward off psychic collapse. These families are frequently referred to coparenting counseling or psychoeducational groups; however, the author proposes that psychoanalytically oriented treatment can best address these parents' unconscious wishes to damage or destroy their own children and the perverse character structure that enables parents to negate their roles in tearing their children apart.

Objective: To evaluate the utility of the theory of planned behavior (TPB) for explaining and predicting leisure time physical activity (LTPA) in the chronic kidney disease population. Study Design: Prospective correlational design. Participants: Eighty men (n=52) and women (n=28) with chronic kidney disease (mean serum creatinine=310.55 [±148.75] μmol/L). Method: Baseline interview assessing attitude, subjective norm, perceived behavioral control, and intention to engage in LTPA. Telephone interview 1 week later assessing frequency and intensity of LTPA. Results: Perceived behavioral control (β=.69) but not attitude (β=.17) or subjective norm (β=.02) was associated with intention to engage in LTPA. Intention (β=.53) but not perceived behavioral control (β=.18) predicted LTPA. Conclusion: These findings provide partial support for the utility of the TPB for explaining LTPA among people with chronic kidney disease. Additional research is required to determine if targeting perceived behavioral control may be an effective means for increasing LTPA in this population.

The literature concerning the relationship between emotional exhaustion and performance led researchers to raise questions about the extent to which the variables are related. In 2 time-lagged samples, the authors found that motivation mediates the emotional exhaustion-job performance relationship. Moreover, the authors found that participants appear to target their investment of resources in response to emotional exhaustion to develop social support through social exchange; specifically, emotional exhaustion was associated with communion striving resources that were manifest in the form of organizational citizenship behaviors targeted at individuals. Implications of this relationship for theories of burnout and for management practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This study tested the efficacy of behavioral treatments for alcohol use disorders (AUD) among men who have sex with men (MSM) and who are at risk for HIV transmission. HIV-negative MSM with current AUD (N = 198) were recruited, offered treatment focused on reducing drinking and HIV risk, and followed during treatment and 12 months posttreatment. Participants (n = 89) accepted treatment and were randomized to either 4 sessions of motivational interviewing (MI) or 12 sessions of combined MI and coping skills training (MI + CBT). Other participants (n = 109) declined treatment but were followed, forming a non-help-seeking group (NHS). MI yielded significantly better drinking outcomes during the 12-week treatment period than MI + CBT, but posttreatment outcomes were equivalent. NHS participants significantly reduced their drinking as well. Service delivery and treatment research implications are discussed.
