Type A and Type B male college students were given the opportunity to display hostile aggression against an insulting confederate on a bogus ESP task, using either aversive noise or a monetary penalty. Preliminary correlational analyses confirmed that Ss' aggressive responding covaried directly with their reported desire to hurt the confederate but was, in contrast, unrelated to their reported desire to help the confederate. Thus, Ss' aggressive behavior was motivated by hostile intentions. Subsequent analyses revealed that Type As were more aggressive and reported a greater desire to hurt the confederate than Type Bs, regardless of the mode of aggression. These data support the results of a recent study which questioned the intuitively appealing assumption that Type As should only display aggressive behavior when motivated by some external achievement goal. 相似文献

Twenty-six previous studies were reviewed which demonstrated a consistent link between children's smoking uptake and exposure at home to an actively smoking older family member. The present study included another variable: the family model of smoking cessation. The smoking practices, intentions, and attitudes of 344 children aged 10–14 in Western Australia were anonymously assessed. Those with ex-smokers but no active smokers at home resembled children who had never been exposed to a smoking family model in being less likely to smoke now or intend to in the future, having fewer smoking chums, and believing that cigarettes had more personal and social disadvantages than their peers who shared households with active smokers. This suggested that any pro-smoking modeling while the ex-smoker was active had been counteracted by modeling of quitting. Implications for intervention were discussed. 相似文献

Previous research has shown that when pigeons are required to peck each of two keys four times in any order for reinforcement, stereotyped response sequences develop, though they are not required by the task. However, despite this stereotypy, sequences are not automatized. They require sufficient attention that sequence performance is disrupted by a concurrent, delayed matching-to-sample task. In the present experiments, pigeons were required to execute response sequences and delayed matching-to-sample concurrently. Experiment 1 showed that the matching task disrupts sequence performance even when the matching sample stimuli do not have to be processed concurrently with sequence execution. The presence of sample stimuli during sequence execution seems to command attention even if the sample stimuli are also available for processing when sequences are not being executed. Experiment 2 used the directed forgetting technique to show that pigeons do seem able to ignore sample stimuli if they are given information that tells them they will not be required to remember those stimuli later. Together, the experiments suggest attentional mechanisms in the pigeon that are not quite involuntary. 相似文献

ABSTRACT. Severely obese men and women (body mass index ≥ 35 ≤ 55 kg/m2; Mage = 44.8 years, SD = 9.3) were randomly assigned to a 6-month physical activity support treatment paired with either nutrition education (n = 83) or cognitive-behavioral nutrition (n = 82) methods for weight loss. Both groups had significant improvements in physical activity, fatigue, self-regulation for eating, and fruit and vegetable intake. Compared to those in the nutrition education group, participants in the behavioral group demonstrated greater overall increases in fruit and vegetable intake and physical activity. These group differences were associated with changes that occurred after Month 3. Increased physical activity predicted reduced fatigue, β = ?.19, p =.01. A reciprocal relationship between the mediators of that relationship, which were changes in self-regulation and fruit and vegetable intake, was identified. There was significantly greater weight loss over six months in the behavioral nutrition group when contrasted with the nutrition education group. Self-regulation for eating and fruit and vegetable intake were significant predictors of weight loss over both three and six months. Findings enabled a better understanding of psychosocial effects on temporal aspects of weight loss and may lead to more effective behavioral treatments for weight loss. 相似文献

Abstract My goal here is to come to terms with the Enlightenment as the horizon of critical social science. First, I consider in more detail the understanding of the Enlightenment in Critical Theory, particularly in its conception of the sociality of reason. Second, I develop an account of freedom in terms of human powers, along the lines of recent capability conceptions that link freedom to the development of human powers, including the power to interpret and create norms. Finally, I show the ways in which the social sciences can be moral sciences in the Enlightenment sense. This account provides us with a coherent Enlightenment standard by which to judge institutions as promoting development, understood in terms of the capabilities necessary for freedom. The relevant social science in this area might include the robust generalization that there has never been a famine in a democratic society. 相似文献

Two experiments were conducted to evaluate the perceptual magnet effect. In Experiment 1, Amer-ican English speakers representing diverse dialects were presented with a fine-grained set of stimuli (varying in just noticeable differences forF1 andF2) and indicated whether they heard “/i/” or “not /i/,” thus delimiting the /i/ portion of the vowel space for individual subjects. Then these same subjects selected their own /i/ prototype with a method-of-adjustment procedure. The data from this experiment were used to synthesize customized prototype and nonprototype stimulus sets for Experiment 2. In Experiment 2,24 of our original 37 subjects completed a discrimination task for each of three conditions, in which vector stimuli varied from the subject’s prototype, the nonprototype, or a foreign vowel (/y/) in 15-mel steps. Subjects displayed higher discrimination, as indexed byd′, for the nonprototype condition than they did for both the prototype and the foreign conditions. In addition, discrimination was better for variants further away from the referent in each condition. However, discrimination was not especially poor for stimuli close to subjects’ individual prototypes—a result that would have yielded the strongest support for the operation of a magnet effect. This negative finding, together with other aspects of our results, raises problems for any theory of vowel perception that relies solely on “one-size-fits-all” prototype representations. 相似文献

The Role of Character Strengths and Importance of Family on Mexican American College Students' Career Decision Self‐Efficacy 下载免费PDF全文

This study examined how character strengths and the importance of family influenced Mexican American college students' (N = 129) career decision self‐efficacy. Findings from a multiple regression analysis indicated that psychological grit and curiosity were significant predictors of career decision self‐efficacy. The authors discuss the importance of these findings and provide recommendations for future research. 相似文献
