Two studies were designed to explore the cross-situational nature of catastrophising and the emotions associated with pain and catastrophising. The crosssituational consistency of catastrophising in response to a finger-pressure procedure and during an episode of headache pain was examined in the first study. The second study examined differences between catastrophisers and noncatastrophisers with respect to state and trait measures of positive and negative emotions. Results of study one indicated that almost half of the subjects remained consistent in their classification as catastrophiser or noncatastrophiser in both pain situations. The majority of subjects that switched classification changed from being classified as catastrophisers during the headache experience to noncatastrophisers during the finger-pressure procedure. Results of the second study indicated that catastrophisers experienced significantly greater fear, sadness, anger, hostility, guilt, disgust, and shame during the finger-pressure procedure as compared to noncatastrophisers. Unexpectedly, catastrophisers were not a homogeneous group in regard to the pattern of negative emotions reported. Catastrophisers with headaches experienced greater sadness in response to finger-pressure pain than catastrophisers without headaches. Theoretical and clinical implications of these findings are discussed. 相似文献

Three experiments are described in which two pictures of isolated man-made objects were presented in succession. The subjects' task was to decide, as rapidly as possible, whether the two pictured objects had the same name. With a stimulus-onset asynchrony (SOA) of above 200 msec two types of facilitation were observed: (1) the response latency was reduced if the pictures showed the same object, even though seen from different viewpoints (object benefit); (2) decision time was reduced further if the pictures showed the same object from the same angle of view (viewpoint benefit). These facilitation effects were not affected by projecting the pictures to different retinal locations. Significant benefits of both types were also obtained when the projected images differed in size. However, in these circumstances there was a small but significant performance decrement in matching two similar views of a single object, but not if the views were different. Conversely, the object benefit, but not the viewpoint benefit, was reduced when the SOA was only 100 msec. The data suggest the existence of (at least) two different visual codes, one non-retinotopic but viewer-centred, the other object-centred. 相似文献

Theories of language production propose that utterances are constructed by a mechanism that separates linguistic content from linguistic structure, Linguistic content is retrieved from the mental lexicon, and is then inserted into slots in linguistic structures or frames. Support for this kind of model at the phonological level comes from patterns of phonological speech errors. W present an alternative account of these patterns using a connectionist or parallel distributed proceesing (PDP) model that learns to produce sequences of phonological features. The model's errors exhibit some of the properties of human speech errors, specifically, properties that have been attributed to the action of phonological rules, frames, or other structural generalizations. 相似文献
