Two studies were conducted which created and tested a scale to measure self-righteousness. Self-righteousness was defined as the conviction that one's behaviors or beliefs are correct, especially in contrast to alternate behaviors or beliefs. In the first study, a 4-item scale to measure general self-righteousness was derived which demonstrated adequate levels of internal consistency and was related to dogmatism and ambiguity intolerance. In the second study, the items were worded to be specific to running a race. This study succeeded in demonstrating that the scale possessed predictive validity. This study also demonstrated the usefulness of rewording the general items to make them specific about the content of self-righteousness.  相似文献

Research on the dimensions of personality represented in the English language has repeatedly led to the identification of five factors (Norman, 1963). An alternative classification of personality traits, based on analyses of standardized questionnaires, is provided by the NEO (Neuroticism, Extraversion, Openness) model (Costa & McCrae, 1980b). In this study we examined the correspondence between these two systems in order to evaluate their comprehensiveness as models of personality. A sample of 498 men and women, participants in a longitudinal study of aging, completed an instrument containing 80 adjective pairs, which included 40 pairs proposed by Goldberg to measure the five dimensions. Neuroticism and extraversion factors from these items showed substantial correlations with corresponding NEO Inventory scales; however, analyses that included psychometric measures of intelligence suggested that the fifth factor in the Norman structure should be reconceptualized as openness to experience. Convergent correlations above .50 with spouse ratings on the NEO Inventory that were made three years earlier confirmed these relations across time, instrument, and source of data. We discuss the relations among culture, conscientiousness, openness, and intelligence, and we conclude that mental ability is a separate factor, though related to openness to experience.  相似文献

Alcohol and social behavior II: the helpful drunkard   总被引:2,自引:0,他引:2  
Can alcohol make people more helpful, and if so, how? We hypothesized that alcohol would increase helping when, if the person were sober, the helping response would be under high inhibitory conflict--that is, when it would be affected by strong instigating and inhibiting pressures. Alcohol's damage to inhibitory processing should then allow instigating pressures to have more influence on the response, increasing helping. We expected that under low inhibitory conflict, when either or both of these response pressures would be weak under sobriety, alcohol would have little effect on helping. In two experiments we examined this reasoning. In Study 1, a mild dose of alcohol increased helping among high-conflict subjects pressured to help with a task they did not like, but did not increase helping among low-conflict subjects who either liked the task or were weakly pressured to help. In Study 2, a somewhat stronger dose of alcohol increased helping among all high-conflict subjects pressured to help with an undesirable task, yet again had no effect among low-conflict subjects weakly pressured to help. These studies provided an experimental demonstration of the role of inhibitory response conflict in mediating alcohol's social effects, and show that this process generalizes to prosocial behavior. Additional evidence from both experiments helped to rule out alternative explanations concerning drinking expectancies, alcohol's ability to enhance mood, and its ability to make the task more bearable.  相似文献

The present study was designed to investigate whether a specific subgroup of learning-disabled children (attention-deficit-disordered, ADD) differed from their normal counterparts on Piagetian tasks of conservation. The subjects were 34 third-and fourth-grade children. Seventeen children had been diagnosed as ADD; the remaining half were designated as normal. The two groups were equivalent in chronological age, mental age, and intelligence. The results indicated significant differences between the two groups on tasks tapping conservation of substance and number. These results may support the theory of a lag in the development of conservation in children with specific learning disabilities (ADD). Implications of the present research for therapeutic and remedial programs that serve ADD children are also discussed.  相似文献
