This research assessed the role of having a coherent explanation of the link between smoking and cervical cancer in motivating women to stop smoking. In the 1st study, women were given a leaflet with either a detailed or a minimal explanation of the link or no leaflet. The leaflets were similarly effective at providing a coherent explanation. In a cross-sectional analysis, having a coherent explanation moderated the relationship between perceived vulnerability and intention: Higher perceived vulnerability to cervical cancer was associated with greater intention to quit smoking only amongst women with a more coherent explanation of the link between smoking and cervical cancer. This finding was replicated in a 2nd study. These results are consistent with H. Leventhal et al.'s (1997) self-regulatory model, which suggests that motivation to change behavior depends not only on perceiving a threat but also on having a coherent model linking the behavior with the threat. 相似文献

In two experiments rats received training on two concurrent appetitive feature-positive discriminations. A preliminary test in Experiment 1 confirmed previous demonstrations of the transfer of occasion-setting properties—the feature from one of these discriminations was better able to facilitate responding to the occasion-set target CS from the second discrimination than to a control stimulus that had not been the subject of occasion-setting. The source of this transfer was investigated in a second phase of training, and in Experiment 2. In both experiments one of the occasion-set CSs was paired with food, and generalization of appetitive conditioned responding from this stimulus to the second occasion-set CS, and to a control cue, was examined. There was more generalization from the first occasion-set CS to the second CS that had also been occasion-set than to the control cue. This is taken as evidence that occasion-set CSs are rendered more similar as a result of their common training history. The implications of these findings for explaining transfer of occasion setting are discussed. 相似文献

In Experiment 1 rats were required to learn a Y-maze in which reward was made available after a given response (e.g. a left turn) regardless of which arm was used as the start-box. Subjects with lesions of the caudate-putamen showed a deficit on this response-learning task compared with control subjects (unoperated animals and rats having lesions of the posterior cortex). In Experiment 2 rats with caudate-putamen lesions were unimpaired when the direction of the turn required to reach the correct goal-box (identified by means of a salient visual intra-maze cue) varied from trial to trial. In the absence of salient intramaze cues, but with enriched room (extra-maze) cues, the rats with caudate-putamen lesions were superior to controls on this task. It is argued that caudate-putamen lesions disrupt a mechanism responsible for processing information about responses, but that the other (spatial) mechanisms responsible for maze-learning remain intact and that caudate-putamen lesions may enhance performance on spatial tasks for which information about responses is irrelevant. 相似文献
