Most of us think of memory in terms of the brain's ability to store and retrieve events, facts, and skills. Philosophers and cognitive scientists seek to understand memory in terms of causation and justification. This article steps back from these considerations to reflect broadly on what memory is. Drawing on the paradigm shift underway in mind sciences, I explore the implications of the emerging understanding of cognition as embodied, embedded, extended, and enacted. This new paradigm undermines epistemological dualism and individualism and makes it possible to view memory as an ecological process. 相似文献
Objectives: This study investigated the mediating role of pain behaviours in the association between pain catastrophising and pain intensity and explored the moderating role of family caregivers’ responses to pain in the link between pain behaviours and pain intensity.
Methods: The sample consisted of 154 chronic pain patients and their family caregivers. Patients completed questionnaires regarding pain intensity, pain catastrophising, pain behaviours and their caregivers’ responses to their pain. Family caregivers reported their responses to the patients’ pain.
Results: Pain catastrophising was associated with pain intensity (r = 0.37) and pain behaviours partly mediated this association. The positive association between pain behaviours and pain intensity was significant only if patients reported that their family caregivers showed high levels of solicitous (effect = .49) and distracting responses (effect = .58), and if caregivers reported to show high levels of solicitous responses (effect = .51). No support was found for negative responses as a moderator neither based on patients’ perception of negative responses nor based on caregivers’ perception of negative responses.
Conclusions: The findings are in line with the idea that family caregivers’ solicitous and distracting responses convey to patients that their condition is serious, which may reinforce patients’ pain and pain behaviours, especially in those who catastrophise. 相似文献
Drawing on social identity theory, we examine how Whites’ race-related beliefs drive their reactions to race-based Affirmative Action Policies (AAPs). Across laboratory and field settings, we find that Whites with relatively high modern racism (MR) or collective relative deprivation (CRD) beliefs perceive greater White disadvantage in organizations that have race-based AAPs, than in organizations that do not. Alternatively, race-based AAPs do not lead to perceptions of White disadvantage among Whites with relatively low MR and CRD beliefs. We also find that White disadvantage mediates the relationship between the combined effects of race-based AAPs, MR beliefs, and CRD beliefs and the perceived fairness of the organization’s selection and promotion policies. Our findings suggest that race-based AAPs do not necessarily lead to perceptions of White disadvantage, but are contingent upon the interpretive lens of Whites’ MR and CRD beliefs, and also offer practical insights for preventing negative reactions to race-based AAPs. 相似文献
The current project investigated affective and strategic determinants of participation in collective actions by taking a multidimensional approach to collective identity (see Cameron, 2004 ) and investigating rational decision‐making processes. A field study was conducted during an important student strike within the Canadian province of Quebec. One hundred and eighty four students attending the province's postsecondary francophone institutions participated in the study. Path modeling was used to investigate two channels to collective action participation. A direct path involved the affective dimensions of identification. An indirect strategic path revealed that pro‐action arguments allowed individuals to derive instrumental value, which in turn led them to participate in collective actions. This indirect influence only occurred at higher self‐control. The results and their implications for understanding participation in collective actions during social movements are discussed. 相似文献
Many problematic responses that occur in intergroup interaction, such as inhibited behavior, restricted disclosure of valuable information, and miscommunication, do not arise from negative attitudes and sometimes are more frequently exhibited by lower-prejudice individuals. Thus it is important to consider how lower-prejudice individuals respond to methods for improving intergroup relations that have been investigated with the prejudiced person in mind. Two studies tested the hypothesis that for lower-prejudice individuals intergroup contact is experienced as being about the ingroup rather than the outgroup, and thus fails to exert its usual effect of paving the way for more positive subsequent intergroup exchanges. As predicted, for individuals seeking to be unbiased an initial exchange with one outgroup member affected feelings about ingroup worthiness, but not reactions to a subsequently encountered outgroup member. The opposite pattern was evident for higher-prejudice individuals, who readily generalized from their experience with one outgroup member to the next. 相似文献
Although there are some indications that dogs (Canis familiaris) use the eyes of humans as a cue during human-dog interactions, the exact conditions under which this holds true are unclear. Analysing whether the interactive modalities of guide dogs and pet dogs differ when they interact with their blind, and sighted owners, respectively, is one way to tackle this problem; more specifically, it allows examining the effect of the visual status of the owner. The interactive behaviours of dogs were recorded when the dogs were prevented from accessing food that they had previously learned to access. A novel audible behaviour was observed: dogs licked their mouths sonorously. Data analyses showed that the guide dogs performed this behaviour longer and more frequently than the pet dogs; seven of the nine guide dogs and two of the nine pet dogs displayed this behaviour. However, gazing at the container where the food was and gazing at the owner (with or without sonorous mouth licking), gaze alternation between the container and the owner, vocalisation and contact with the owner did not differ between groups. Together, the results suggest that there is no overall distinction between guide and pet dogs in exploratory, learning and motivational behaviours and in their understanding of their owner's attentional state, i.e. guide dogs do not understand that their owner cannot see (them). However, results show that guide dogs are subject to incidental learning and suggest that they supplemented their way to trigger their owners' attention with a new distal cue. 相似文献
In this paper, a logic for reasoning about coalitional power is developed which explicitly represents agents’ preferences
and the actions by which the agents can achieve certain results. A complete axiomatization is given and its satisfiability
problem is shown to be decidable and EXPTIME-hard. 相似文献
