Although achievement goal and expectancy-value theories are both dominant in the achievement motivation literature, the relation between goals and expectancy-value variables in predicting achievement-related behaviors remains unclear. The present study evaluated the empirical validity of four contrasting theoretical conceptions which posit that (1) goals and expectancy-value variables are independent predictors of achievement-related outcomes (2) goals predict expectancy-values, (3) goals mediate the relation between expectancies and task-values, and (4) goals partially mediate the relation between expectancy-values and achievement outcomes, in predicting course performance, career intentions and academic aspirations. Path models evaluating these conceptions were tested separately in mathematics and language arts domains among 697 6th and 8th grade students. Results supported the fourth theoretical approach suggesting that expectancy-value variables predict achievement-related outcomes both directly and indirectly through achievement goals. These findings provide insight about the relation between expectancy-value and achievement goal theories and highlight their complementary role in predicting achievement behaviors.  相似文献

The harmfulness of anti‐Semitic beliefs is widely discussed in current political and legal debates (e.g., Cutler v. Dorn). At the same time, empirical studies of the psychological consequences of such beliefs are scarce. The present research is an attempt to explore the structure of contemporary anti‐Semitic beliefs in Poland—and to evaluate their predictive role in discriminatory intentions and behavior targeting Jews. Another aim was to determine dispositional, situational, and identity correlates of different forms of anti‐Semitic beliefs and behavior. Study 1, performed on a nation‐wide representative sample of Polish adults (N = 979), suggests a three‐factorial structure of anti‐Semitic beliefs, consisting of: (1) belief in Jewish conspiracy, (2) traditional religious anti‐Judaic beliefs, and (3) secondary anti‐Semitic beliefs, focusing on Holocaust commemoration. Of these three beliefs, belief in Jewish conspiracy was the closest antecedent of anti‐Semitic behavioral intentions. Study 2 (N = 600 Internet users in Poland) confirmed the three‐factor structure of anti‐Semitic beliefs and proved that these beliefs explain actual behavior toward Jews in monetary donations. Both studies show that anti‐Semitic beliefs are related to authoritarian personality characteristics, victimhood‐based social identity, and relative deprivation.  相似文献

Objective: This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4–6 years) and whether these RAA measures are predictive of physical activity.

Design: Longitudinal observational study with repeated measures over six months.

Measures: RAA variables were measured using a novel choice paradigm between physically active and sedentary pastimes. Relative reinforcing value, covariates (sex, age, deprivation and BMI) and physical activity by accelerometry (primary outcome) were also measured.

Results: RAA cognitions could be measured with acceptable retest reliability and discriminant validity and social norms regarding parents and teachers (but not friends) were correlated with physical activity and change in physical activity when relative reinforcing value and other covariates were controlled for.

Conclusions: RAA cognitions can be reliably measured in primary school children aged 4–6 and RRA measures appear useful in understanding children’s activity choices and may potentially inform future interventions.  相似文献

Emotional eating, the tendency to eat when experiencing negative affect, is prevalent in morbid obesity and may indicate that ways to deal with emotions are disturbed. Our aim was to compare emotion processing and regulation between 102 women with morbid obesity who apply for bariatric surgery and 102 women from the general population (control group) and to examine in the group with morbid obesity the association of emotion processing and regulation with emotional eating. The group with morbid obesity reported higher scores on difficulty identifying feelings (alexithymia, p?=?0.002) and suppression of emotions (p?=?0.003) than the control group. In the women with morbid obesity, more negative affect and a higher difficulty identifying feelings were correlated with more emotional eating (r?=?0.36 and r?=?0.35, p?<?0.001). Our study suggests that negative emotions and unhealthy emotion processing may play a role in emotional eating, and it indicates the possible relevance of emotion processing and emotional regulation as initiating or perpetuating mechanisms in morbid obesity.  相似文献

A common question of interest to researchers in psychology is the equivalence of two or more groups. Failure to reject the null hypothesis of traditional hypothesis tests such as the ANOVA F‐test (i.e., H0: μ1 = … = μk) does not imply the equivalence of the population means. Researchers interested in determining the equivalence of k independent groups should apply a one‐way test of equivalence (e.g., Wellek, 2003). The goals of this study were to investigate the robustness of the one‐way Wellek test of equivalence to violations of homogeneity of variance assumption, and compare the Type I error rates and power of the Wellek test with a heteroscedastic version which was based on the logic of the one‐way Welch (1951) F‐test. The results indicate that the proposed Wellek–Welch test was insensitive to violations of the homogeneity of variance assumption, whereas the original Wellek test was not appropriate when the population variances were not equal.  相似文献

The burden of HIV disease is concentrated in sub-Saharan Africa, particularly in South Africa (SA). Whilst there have been many studies conducted on the biomedical and socio-psychological aspects of HIV and AIDS, insufficient attention has been paid to the quality of life of those infected with the virus. The primary purpose of the study was to determine the predictors of quality of life enjoyment and satisfaction (Q-LES) among individuals infected with HIV. A battery of questionnaires, which included the Hospital Anxiety and Depression Scale (HADS) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), were administered to 121 participants. Data was analysed using SPSS. Of the total sample (n = 121), 74% were females. The study found that a large proportion (49.5%) of the sample within the age group 25–49 years old experienced psychological distress. Those who were not on antiretroviral treatment (ART) were significantly affected (66%). Psychological distress was significantly prevalent among HIV positive individuals and also the strongest predictor of Q-LES among these individuals.  相似文献

Abstract

The aim of the study was to investigate the relationships between social anxiety, social skills and estimated cost as well as expectancy of negative social/non-social events. One hundred and twenty-six students (half males and half females) filled in the Social Phobia and Anxiety Inventory (SPAI), the Social Skills Inventory (SSI), and measures of expectancy and estimated cost of negative social and non-social events. Social anxiety was negatively correlated with self-reported social skills. Further, social anxiety was strongly related to both expectancy and estimated cost of negative social, as opposed to non-social, events. Social skills were related to expectancy, but not to estimated cost of negative social events. Finally, the correlation between social anxiety and expectancy of negative social events disappeared when social control (measured with a subscale of SSI) was partialized out of the relationship, whereas the correlation between social anxiety and estimated cost of negative social events did not. Potential therapeutic implications are discussed.  相似文献

Abstract

The purpose of this study was to determine the association between the occurrence of stressful life events and internalizing and externalizing problems, and to analyze longitudinally buffering effects of supportive family relationships. To this end, 100 Spanish adolescents were studied twice, when they were in mid-adolescence (15–16 years) and two years later. They completed questionnaires regarding stressful life events, family relationships, and adolescent adjustment. Results showed that high quality parent-adolescent relationships protected boys and girls against the negative consequences of stressful life events on externalizing, but not internalizing, symptoms. The adolescents who enjoyed good relationships with their parents in mid-adolescence did not increase their externalizing problems in late adolescence as consequence of the occurrence of stressful events. However, these stressors did lead to an increase in the number of externalizing problems when the family relationships were of a middle or low quality. These results highlight the important role that supportive family relationships play in the behavioral adjustment of adolescents, protecting them against some negative consequences of stressful life events, and suggest the relevance of supporting parents through resources such as parent education in order to help them to improve their relationships with their adolescents.  相似文献

The regional content expansion of Thomson Reuters (formerly ISI) Web of Science added approximately 1,600 journals to the database with a regional as opposed to international focus. Web of Science coverage has grown to reflect the changing nature of global research publication trends and the additional regional journals provide greater visibility to high quality local studies beyond their traditional boundaries. The cited references indexed from the regional journals represent the influence of those journals on both the global and local research communities. This study analyses the impact of adding Spanish regional journals to Web of Science on the publication and citation patterns of Spanish research. The findings demonstrate a recent increase in research output from Spain and this is explained by more Spanish research being produced rather than due to the indexing of more Spanish journals; indeed it is shown that the majority of Spanish research is not published in Spanish journals. An analysis of Spanish journal citations uncovers a Spanish regional citation network previously undetected and serves as valuable information for evaluators of Spanish journals.  相似文献

The spatial Stroop effect (slower left/right responses to left/right pointing arrows when they appear at spatially incongruent than at congruent locations) has often been used to examine the processing of irrelevant spatial information. We present data from two experiments in which the magnitude of such location-based interference is drastically reduced when the location of the arrow is precued by a spatial noninformative cue. The main aim of the present study was to clarify whether such modulation takes place at perceptual or at response-related stages of processing. First, we manipulated the spatial compatibility between the direction of the arrow and the location of the response so that each subject would respond with spatially compatible vs. incompatible key presses for each half of the experiment. We found that such manipulation did not have any effect on the standard reduction of the congruency effect by peripheral cues. In a second experiment, subjects made left/right key presses to directional arrows pointing bottom/up, which could appear equally often at left/right/bottom/up locations. In cued trials, we found a reduction of the congruency effect on the vertical axis (stimulus location-direction congruency), whereas congruency was unaffected by cueing in targets presented on the horizontal axis (stimulus-response location congruency). According to these results, we conclude that spatial noninformative cues modulate spatial Stroop interference by reducing the conflict between stimulus dimensions at perceptual- rather than motor-related stages of processing.  相似文献
