This paper reports the results of two experiments designed to test predictions from the mood-as-input hypothesis about the factors that contribute to the ending of a worry bout. Experiment 1 looked at changes in self-reported mood across a catastrophising interview task. Experiment 2 investigated whether there were any changes in stop rule deployment between the beginning and end of a catastrophising interview task. Experiment 1 demonstrated that worriers tended to show increases in negative mood and decreases in positive mood over the course of catastrophising. In Experiment 2, participants exhibited a significant shift away from endorsing the use of 'as many as can' stop rules and a significant increasing tendency to endorse the use of 'feel like continuing' stop rules over the course of catastrophising. These results suggest that worriers exhibit increases in negative mood across the worry bout, but shift from the use of 'as many as can' to 'feel like continuing' stop rules. Mood-as-input hypothesis predicts that if high worriers ask the question "do I feel like continuing?" in the context of increasing negative mood, this will imply that the activity is no longer enjoyable or profitable and should be terminated. The results are discussed in the context of mood-as-input accounts of pathological worrying and the therapeutic implications of these findings are reviewed. 相似文献

Shape recognition can be achieved through vision or touch, raising the issue of how this information is shared across modalities. Here we provide a short review of previous findings on cross-modal object recognition and we provide new empirical data on multisensory recognition of actively explored objects. It was previously shown that, similar to vision, haptic recognition of objects fixed in space is orientation specific and that cross-modal object recognition performance was relatively efficient when these views of the objects were matched across the sensory modalities (Newell, Ernst, Tjan, & Bülthoff, 2001). For actively explored (i.e., spatially unconstrained) objects, we now found a cost in cross-modal relative to within-modal recognition performance. At first, this may seem to be in contrast to findings by Newell et al. (2001). However, a detailed video analysis of the visual and haptic exploration behaviour during learning and recognition revealed that one view of the objects was predominantly explored relative to all others. Thus, active visual and haptic exploration is not balanced across object views. The cost in recognition performance across modalities for actively explored objects could be attributed to the fact that the predominantly learned object view was not appropriately matched between learning and recognition test in the cross-modal conditions. Thus, it seems that participants naturally adopt an exploration strategy during visual and haptic object learning that involves constraining the orientation of the objects. Although this strategy ensures good within-modal performance, it is not optimal for achieving the best recognition performance across modalities. 相似文献

Three methods of voice restoration--tracheosophageal speech (TEP), oesophageal speech, electrolarynx--are available following total laryngectomy. TEP produces better voice quality compared with other methods and is assumed to result in better quality of life. Little evidence exists to support the relationship between voice quality and quality of life, however. Advertising this study through several leading laryngectomy charities resulted in the completion of 226 questionnaires (TEP = 147; oesophageal speech = 42; electrolarynx = 37) comprising the Short Form 36 (SF-36) quality of life measure and questions examining perceived voice intelligibility. Additionally, 89 questionnaires comprising only the SF-36 were completed by participants who reported having no serious medical problems, to form a healthy control group. Results indicate that improved voice quality does not result in widespread benefits to quality of life. On only a few dimensions were there differences between voice restoration method: electrolarynx and TEP better than oesophageal speech with respect to pain, TEP better than oesophageal speech with respect to role limitation: physical problems. Additionally whilst widespread differences between voice restoration methods did not occur, all three groups had a worse quality of life compared with the healthy control group. Implications of the results for the selection of voice restoration method to maximize quality of life are discussed. 相似文献

In order to understand better the processes involved in the perception of shape through touch, someelement of control is required over the nature of the shape presented to the hand and the presentation timing. To that end, we have developed a cost-effective, computer-controlled apparatus for presenting haptic stimuli using active touch, known as a virtual haptic display (VHD). The operational principle behind this device is that it translates black and white visual images into topographic, 2-D taxel (tactile pixel) arrays, along the same principle using in Braille letters. These taxels are either elevated or depressed at any one time representing white and black pixel colors of the visual image, respectively. To feel the taxels, the participant places their fingers onto a carriage which can be moved over the surface of the device to reveal a virtual shape. We conducted two experiments and the results show that untrained participants are able to recognize different, simple and complex, shapes using this apparatus. The VHD apparatus is therefore ideal at presenting 2-Dshapes through touch alone. Moreover,this device and its supporting software can also be used for presenting computer-controlled stimuli in cross-modal experiments. 相似文献

Northern Ireland is characterised by extensive segregation between its predominantly Catholic and Protestant communities. With the aim of overcoming this segregation, the current study experimentally evaluated the effectiveness of electronic or E-contact as a novel indirect contact and prejudice-reduction strategy. Here, Catholic and Protestant participants were not required to meet physically but were involved in a collaborative and goal-orientated online interaction with a member of the other community. As predicted, E-contact improved both Catholics’ and Protestants’ outgroup attitudes via improved contact expectancies and reduced intergroup anxiety. These findings provide support for the contemporary role of online interactions in actively overcoming the physical and psychological barriers that often prevent prejudice reduction in segregated communities. 相似文献

The Body Ownership Thesis states that each person owns her body. I address a prominent objection, the Generation Problem: the Body Ownership Thesis apparently implies that parents own their children: as we own the fruit of our property, if a parent owns her own body, she must own her child and her child's body. I argue that a person does not own the fruit of her property when that fruit is a person or the body of a person. Persons have conclusive title to their bodies, but only defeasible title to the fruits of their bodies. 相似文献

Although the detection and experience of symptoms often stimulates an appropriate decision as to whether to visit to a healthcare professional (HCP), there are many occasions when it does not. Sometimes, people seek help for minor, transient conditions which would have resolved without the attention of a HCP, whereas at other times help is not sought for signs of life-threatening disease. Help-seeking behaviour concerns not only the decision of whether to seek help or not, but also the timing of that decision. The timing of consultations with HCPs has implications for our health, quality of life, treatment options and for the cost of healthcare services. This article discusses research and theory on help-seeking behaviour, with attention to the challenges of methods and models used in this area of research. One particular model, the ‘General Model of Total Patient Delay’, is outlined and critiqued to demonstrate the complex processes involved and highlight areas in need of further research and development. 相似文献

Abstract: I propose a counterexample to naturalistic representational theories of phenomenal character. The counterexample is generated by experiences of novel colours reported by Crane and Piantanida. I consider various replies that a representationalist might make, including whether novel colours could be possible colours of objects and whether one can account for novel colours as one would account for binary colours or colour mixtures. I argue that none of these strategies is successful and therefore that one cannot fully explain the nature of the phenomenal character of perceptual experiences using a naturalistic conception of representation. 相似文献
