Smoking cessation among pregnant adolescents remains a complex and unresolved issue. The purpose of this study was to examine adolescents' knowledge of the detrimental effects of smoking on pregnant women and fetuses and its relationship to efforts to quit smoking. The sample consisted of 71 pregnant adolescents, and a three-group randomized intervention design-Teen FreshStart (TFS), Teen FreshStart with buddy (TFSB), and usual care control (UCC)-was used. Instruments included a demographic questionnaire, a smoking history questionnaire, and an 11-item scale measuring knowledge of the effects of smoking during pregnancy. For the entire sample, knowledge scores increased significantly (p = .000) from T1 (preintervention) to T2 (postintervention), and the adolescents who quit smoking had significantly higher knowledge at T2 (p = .028) and greater increases (T1 to T2) in their knowledge (p = .019) than did those who did not quit. Together, the TFS and TFSB groups had significantly higher knowledge at T2 (p = .017) and a significantly greater increase in knowledge from T1 to T2 (p = .005) than did the UCC group. This also held true when the TFS and TFSB groups were examined individually. Each had significantly higher knowledge at T2 (TFS, p = .029; TFSB, p = .008) and a significantly greater increase in knowledge from T1 to T2 (TFS, p = .007; TFSB, p = .009) than did the UCC group. Furthermore, despite the small sample sizes, within-group comparisons showed (a) no significant differences between quitters and nonquitters in the UCC group, (b) significantly higher knowledge at T2 (p = .052) and a trend indicating greater increases in knowledge from T1 to T2 (p = .092) for the quitters compared with the nonquitters in the TFS group, and (c) a trend for adolescents in the TFSB group who quit smoking to have greater increases in knowledge compared with those who did not quit (p = .158). These results indicate the need for continued inquiry into the relationship between pregnant teenagers' health knowledge and decisions to stop smoking.  相似文献

The present study examined the effect of applicant influence-tactic use on recruiter perceptions of fit. Two tactics, ingratiation and self-promotion, were expected to have positive effects on recruiter perceptions of fit and on recruiter hiring recommendations. In addition, the authors expected recruiter fit perceptions to mediate the relationship between applicant influence tactics and recruiter hiring recommendations. Results suggested that ingratiation had a positive effect on perceived fit and recruiter hiring recommendations (and indirectly, on receipt of a job offer). In addition, perceived fit mediated the relationship between ingratiation and hiring recommendations. The effects of self-promotion on fit and hiring recommendations were generally weak and nonsignificant. Implications and directions for future research are discussed.  相似文献

We report that post-training inactivation of basolateral amygdala region (BLA) with muscimol impaired memory for contextual-fear conditioning (as measured by freezing) and intra-BLA norepinephrine enhanced this memory. However, pre-exposure to the context eliminated both of these effects. These findings provide a likely explanation of why an earler study failed to observe that the BLA modulates contextual fear conditioning-they pre-exposed their rats to the context. These results also suggest that the amygdala modulates the storage of the context fear memory and may do so by influencing the storage of the representation of the context in which the shock occurred.  相似文献

Two studies compared young and older adults' memory for location information after brief intervals. Experiment 1 found that accuracy of intentional spatial memory for individual locations was similar in young and older participants for set sizes of 3 and 6. Both groups also encoded individual locations in relation to the larger configuration of locations. Experiment 2 showed that like young adults, older adults' latency to respond to a test probe in a letter working memory task was negatively influenced by spatial information that was irrelevant to the task. This interference effect indicated preserved incidental memory for spatial information in older adults. Together, these data suggest that initial encoding of spatial information for relatively small numbers of items is largely preserved in healthy older adults and that representations of spatial information persist over short intervals.  相似文献

Self-discrepancy theory (E. T. Higgins, 1987) hypothesizes that actual-ideal discrepancies are uniquely related to dejection emotions, whereas actual-ought discrepancies are uniquely related to agitation emotions. A review of the literature testing this hypothesis supports an affirmative-answer to the question "Is there an effect?" However, as the results of J. P. Tangney, P. M. Niedenthal, M. V. Covert, and D. H. Barlow's (1998) study indicate, the predicted unique relations are not always found. Their article contributes to the development of self-discrepancy theory by shifting attention to the second-generation question "When is there an effect?" Four variables that moderate the likelihood of finding unique discrepancy-emotion relations are discussed in the present article: the magnitude of a self-discrepancy, the accessibility of a self-discrepancy, the applicability and relevance of a self-discrepancy in a current context, and the importance of a self-discrepancy to the person.  相似文献

This study empirically tests Locke's theory that the importance of a job satisfaction factor to an individual is already reflected in the individual's responses to the specific questions, Responses from a job satisfaction survey carried out by a large Canadian company were analyzed using a second generation causal modeling technique, Partial Least Squares. The results supported Locke's theory in that weighting the responses with the individual's importance factors did not improve the variance explained in the job satisfaction model. Further analysis indicated that there were differences between groups with high job satisfaction and groups with low satisfaction, differences in job satisfaction for different levels of service length, and that the differences in job satisfaction across gender were not large.  相似文献

This paper examines whether arousal is a necessary component of the motivation to reduce dissonance. Alternative responses to attitude-behavior inconsistency include attitude change, explaining the behavior by a consonant cognition (i.e., low choice), and attributing the dissonance-induced state to an alternative source, such as the purported side effects of an ingested “drug.” For conditions in which there are few consonant cognitions (i.e., high choice), a comparison of different “drug” conditions in which attitude change does or does not occur was expected to clarify which components of the dissonance-induced state mediate attitude change. Attitude change occurred in high choice conditions where the “drug” was described as pleasant, but not in high choice conditions where the “drug” was described as unpleasant or in a low choice condition. In addition, when the “drug” was descibed as arousing there was, if anything, more attitude change than when the “drug” was described as nonarousing. These results suggest that unpleasantness and not arousal per se is the motivating factor in dissonance reduction. The effects of the passage of time and reinstating the counterattitudinal behavior on the alternative responses to attitude-behavior inconsistency were also examined. Subjects returned 2 weeks later, stated their attitudes, recalled their original counterattitudinal essay, and again stated their attitudes. Although there was a general decrease in attitude change during this period, the pattern of attitude change remained basically the same. Attitude change following reinstatement increased from its original level only in those conditions where it had been initially attenuated through misattribution or a consonant cognition.  相似文献

Bertelson (1963), and others more recently, have observed that when the same stimulus is presented consecutively the reaction time (RT) to the second presentation is faster than the RT to the first presentation. In Experiments 1 and 2, two-dimensional stimuli are used in a discrete four-choice RT task where the stimuli can either be completely repeated, partially repeated, or completely different. In Experiment 3, three-dimensional stimuli were used in a discrete eight-choice RT task where the stimuli can either be completely repeated, partially respeated with respect to two dimensions, partially repeated with respect to one dimension, or completely different. The partial repetition of multidimensional stimuli showed a significant facilitation effect on RT with all sets of stimuli used in the present experiments. This result is discussed in respect to the various possible loci of the repetition effect.  相似文献

Two studies explored the relevance of self-discrepancies for body dissatisfaction and disordered eating. In Study 1, actual:ideal self-discrepancies of female undergraduates correlated with body shape dissatisfaction independent of Ss' body mass and number of appearance-related self-beliefs; actual:ought discrepancy was discriminantly associated with anorexic-related attitudes and behaviors. In Study 2 (using a mixed-gender sample), bulimic-related behaviors were associated with a form of actual:ideal discrepancy (unfulfilled positive potential) whereas anorexic-related symptoms were associated with actual:ought discrepancy. Both genders showed the predicted relations between self-discrepancies and disordered eating, and the predicted associations remained even when appearance-related attributes were excluded from scoring of self-discrepancies.  相似文献
