In spatial sequence synaesthesia (SSS) ordinal stimuli are perceived as arranged in peripersonal space. Using fMRI, we examined the neural bases of SSS and colour synaesthesia for spoken words in a late-blind synaesthete, JF. He reported days of the week and months of the year as both coloured and spatially ordered in peripersonal space; parts of the days and festivities of the year were spatially ordered but uncoloured. Words that denote time-units and triggered no concurrents were used in a control condition. Both conditions inducing SSS activated the occipito-parietal, infero-frontal and insular cortex. The colour area hOC4v was engaged when the synaesthetic experience included colour. These results confirm the continued recruitment of visual colour cortex in this late-blind synaesthetes. Synaesthesia also involved activation in inferior frontal cortex, which may be related to spatial memory and detection, and in the insula, which might contribute to audiovisual integration related to the processing of inducers and concurrents. 相似文献

Thirty-five graduate and undergraduate students, owners of dogs and cats, were asked to respond in writing to a several questions regarding their relationship with their pet. In this retrospective analysis, we discuss aspects that describe the pet-owner relationship, including attachment and the role played by the pet in the owner's life (e.g., emotional support, the pet being seen as a family member). Most of the participants felt that their pet's loss caused great pain; some considered that even if they had suffered greatly, the death of their pet was not felt more intensely and severely than the death of any other family member or a friend. 相似文献

Although research demonstrated that people can mentally manipulate and synthesize visual elements into a creative object, the role that vividness of visual imagery plays on creative imagery is still unclear. This study explored the relationships between vividness of visual imagery and 3 dimensions of creative imagery: originality, practicality, and mental spatial transformations of visual elements. Fifty-three participants performed the creative mental synthesis task and completed the Vividness of Visual Imagery Questionnaire (VVIQ). Results revealed a positive relationship between vividness and the practicality dimension of objects. No relationship was found either between vividness and originality or between vividness and transformational complexity. The association vividness–practicality seems to reflect the ability to use pictorial information of imagery when people generate functional objects that belong to specific categories. Future research directions are discussed. 相似文献

The present research examines the effectiveness of intergroup contact between 167 Italian hospital workers and foreign patients in reducing prejudice towards immigrants in general. The outcomes of contact at work were analysed controlling for the influence of contact outside the workplace and through mass media, and taking into account the role of empathy, anxiety and group membership salience. Results indicate that the beneficial effects of contact at work were partially mediated by increased empathy and reduced anxiety, experienced both in the work environment and towards immigrants in general. Finally, high levels of group membership salience facilitated the influence of contact on intergroup emotions. These findings show that contact at work can be a powerful means to reduce prejudice, thanks to its capacity to evoke changes in affective responses. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Previous studies found little or no transfer of adaptation from reactive saccades to arm pointing movements, which suggests that the two motor systems rely on distinct adaptive mechanisms. However, this conclusion is based on experiments about the adaptation of response amplitudes, which is known to follow somewhat different principles than the adaptation of response directions. In the present study, we therefore investigate whether adapting the direction of reactive saccades will transfer to arm movements. We also test transfer in the opposite direction, from the arm to the eyes. Participants executed aimed saccades or arm movements from a central starting point towards visual targets in the participants' frontal plane. Targets were presented in eight possible locations along a circle of 20 cm radius about the starting point; each remained for 200 ms in one position, and was then displaced along the circle by -15 degrees . Participants from group E adapted to these double-stepped targets while executing eye movements, and were then tested for transfer while executing arm movements. The reciprocal design was used in participants from group A. Adaptive change in group A was about 14 degrees , while in group E it was only about 7 degrees . Transfer of adaptation was substantial, and was more pronounced when using the arm (i.e., eye-to-arm transfer in group E) rather than the eyes (i.e., arm-to-eye transfer in group A). Strong aftereffects were yielded in both groups. This pattern of findings implies that the adaptive change observed in our study was mainly based on recalibration rather than on cognitive strategies (strong aftereffects), that eyes and arm had access to a common adaptive mechanism (substantial transfer), and that the arm had better access than the eyes (larger adaptation and transfer when using the arm). When considering this outcome along with the available literature, it appears that arm and eyes may rely sometimes on a common and sometimes on distinct adaptive mechanisms, depending on the adapted parameter and on the nature of the motor task. 相似文献

This work examines how people interpret the sentential connective "or", which can be viewed either inclusively (A or B or both) or exclusively (A or B but not both). Following up on prior work concerning quantifiers (Bott & Noveck, 2004; Noveck, 2001; Noveck & Posada, 2003), which shows that the common pragmatic interpretation of "some", some but not all, is conveyed as part of an effortful step, we investigate how extra effort applied to disjunctive statements leads to a pragmatic interpretation of "or", or but not both. Experiment 1 compelled participants to wait for three seconds before answering, hence giving them the opportunity to process the utterance more deeply. Experiments 2 and 3 emphasized "or", either by visual means ("OR") or by prosodic means (contrastive stress) as another way to encourage participants to apply more effort. Following a relevance-theoretic line of argument, we hypothesized that conditions encouraging more processing effort would give rise to more pragmatic inferences and hence to more exclusive interpretations of the disjunction. This prediction was confirmed in the three experiments. 相似文献

Eye and hand movements can adapt to a variety of sensorimotor discordances. Studies on adaptation of movement directions suggest that the oculomotor and the hand motor system access the same adaptive mechanism related to the polarity of a discordance, because concurrent adaptations to opposite directed discordances strongly interfere. The authors scrutinized whether participants adapt their hand and eye movements to opposite directions (clockwise/counterclockwise) when both motor systems are alternatingly exposed to opposite directed double steps, and whether such adaptation is influenced by the allocation of effector to adaptation direction. The results showed that hand and eye movements adapted to opposite directions, but adaptation was biased to the counterclockwise direction. Aftereffects emerged nearly unbiased and independently for both motor systems. The authors conclude that the oculomotor and the hand motor system use independent mechanisms when they adapt to opposite polarities, although they interact during adaptation or concurrent performance. 相似文献
