This study tested the hypothesis that symptoms of depression are negatively related to relational quality, which in turn is negatively related to feelings of loneliness among members of dating couples. Potential sex differences in the magnitude of association between depressive symptoms and relational quality, and potential emotional contagion of depressive symptoms within dyads, were also explored. One hundred and one dating couples completed the Oral History Interview along with other measures of relational quality, depressive symptoms, and loneliness. Results for both males and females indicated that depressive symptoms were negatively associated with relational quality and that relational quality was negatively associated with loneliness. The association between symptoms of depression and poor relational quality was similar for females and males. There was no evidence suggestive of emotional contagion in these dating couples. Implications of these findings and their potential limitations are discussed. 相似文献

Two interventions aimed at preventing depressive symptoms in women living in Western Australian rural communities were evaluated against a no‐intervention control condition. The standard intervention was based upon traditional cognitive‐behaviour treatments for depression; the experimental intervention was based upon prevention strategies derived from the learned helplessness model of depression (e.g. Peterson, Maier, & Seligman, 1993 ). Seventy‐six women were randomly assigned to either the standard or the experimental group, and a further 20 women formed a no‐intervention control group. The standard group showed a reduction in depressive symptoms at post‐test, but no effects at 6‐week or 6‐month follow‐ups. In contrast, a reduction in depressive symptoms did not appear for the experimental group until the 6‐week follow‐up at which time a less depressive attributional style was also evident; these effects were even more pronounced at the 6‐month follow‐up. The no‐intervention control group showed no changes across time. It is argued that these results support the applicability of prevention strategies based on the learned helplessness model to this population. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

The concept of diagnostic utility was used to create questions that would differentially affect deception detection accuracy. Six deception detection studies show that subtle differences in questioning produced accuracy rates that were predictably, substantially, and reliably above and below chance. The first 3 detection studies demonstrate that diagnostically useful questioning can reliably achieve accuracy rates over 70% with student and experienced judges. The fourth and fifth experiments demonstrated negative diagnostic utility among federal investigators but not students. The final experiment crossed 3 sets of interview questions with experience. Strong question effects produced a swing in accuracy from 32 to 73%. A questioning by experience interaction was also obtained. 相似文献

In the first of two experiments, three cotton rats (Sigmodon hispidus) and three albino rats were exposed to instrumental escape, unsignaled avoidance, and signaled avoidance, in that order. All subjects learned the escape procedure quickly, with the albino rats having generally shorter latencies, higher response rates, and requiring fewer sessions to reach the criterion. When the avoidance contingency was introduced, the cotton rats continued to respond almost entirely in the presence of the shock, whereas the albino rats responded in its absence, thus displaying effective avoidance behavior. Introduction of a pre-aversive stimulus did not improve the performance of the cotton rats. In the second experiment, five cotton rats and four albino rats were exposed to a free-operant (Sidman) avoidance procedure with a shock-shock interval of 3 sec and a response-shock interval of 20 sec. The cotton rats initiated responding at lower shock intensities than the albino rats, but their asymptotic avoidance responding was far less effective. 相似文献

An attempt was made to reduce the cigarette smoking of three subjects by means of a special cigarette case that delivered aversive shock when opened. The number of cigarettes smoked was recorded by a counter in the cigarette case. The validity of the counter readings as a measure of smoking was obtained by a specially designed participant-observer technique. It was found that the rate of smoking decreased as a function of the intensity of the shock. Also, the smoking returned to its previously unpunished level after the shock punisher was discontinued. Both of these findings confirm the results of laboratory studies of punishment of simpler responses and extends them to more complex responses in a naturalistic situation. Surprisingly, the duration for which the apparatus was worn also decreased as a function of the intensity of the shock. This finding reveals that this aversive shock technique produced avoidance behavior that prevents the technique from having extensive applicability for eliminating smoking. The same limitation may apply to the use of aversive shock for eliminating other undesirable behaviors. 相似文献
