AbstractObjective: The role of affectively oriented risk beliefs in explaining health behaviors has not been examined in the context of physical activity or in diverse study populations. We evaluated whether affective risk beliefs account for unique variance in physical activity intentions and behavior above and beyond that accounted for by cognitive risk beliefs.Design: A cross-sectional survey of socio-demographically diverse US residents (N?=?835; 46.4% no college training; 46.7% minority racial/ethnic ancestry; 42.6% men).Main outcome measures: Physical activity intentions and behavior.Results: Hierarchical linear regressions showed that affective risk beliefs accounted for variance in physical activity intentions beyond that predicted by socio-demographics and cognitive risk beliefs (F-change ps<.001). Specifically, intentions were higher among people with higher anticipated regret (ps<.001) and with higher absolute feelings of risk (ps<.05) or worry (ps<.05). There was an indirect relationship between perceived absolute likelihood and intentions through anticipated regret and feelings of risk. Neither cognitive nor affective risk beliefs accounted for variance in physical activity behavior (F-change ps>.05), but unsurprisingly, behavior was positively associated with physical activity intentions (p<.001).Conclusion: Future interventions could target affective risk beliefs—particularly anticipated regret—to increase intentions, and then add other intervention components to bridge the intention–behavior gap. 相似文献

It is generally recognized that modern cities pose many problems for their inhabitants and contribute to environmental damage. However, neither planners nor scientists give adequate consideration to cities’ place in the evolutionary process and the planet's ecological system. By recognizing these connections and natural laws, planning would become more realistic, and meaningful progress could be made in solving serious social and environmental problems. Some basic problems influencing urban form are discussed, and a schematic example of how we might approach the planning of urban settlements is presented. 相似文献

Correcting distorted perception of sleep in insomnia: a novel behavioural experiment? 总被引:5,自引:0,他引:5
Patients with primary insomnia overestimate their sleep onset latency (SOL) and underestimate their total sleep time (TST). The present study aimed to test the utility of a novel behavioural experiment designed to correct distorted perception of sleep among patients diagnosed with primary insomnia. Individuals with primary insomnia were asked to wear an actigraph and keep a sleep diary for three nights. On the following day, half were shown the discrepancy between the data recorded on the actigraph and their sleep diary (Shown-Discrepancy Group), the other half were not shown the discrepancy (No-Demonstration Group). Participants were then asked to wear the actigraph and keep a sleep diary for three further nights. Following the behavioural experiment, the Shown-Discrepancy Group estimated their SOL more accurately and reported less anxiety and preoccupation about sleep compared to the No-Demonstration Group. The theoretical and clinical implications of these findings are discussed. 相似文献

In this paper I argue for a theory of perception distinct both from classical sense‐datum theories and from intentionalist theories, that is theories according to which one perceives external objects by dint of a relation with a propositional content. The alternative I propose completely rejects any representational element in perception. When one sees that an object has a property, the situation or state of affairs of its having that property is one's perception, so that the object and property are literally part of one's mind. The most obvious objection to this view is that it embodies a rampant form of idealism. It is argued to the contrary, via consideration of the metaphysics of situations, that the theory is entirely consistent with a robustly realist view of the world. 相似文献

Vernat, J.-P. & Gordon, M. S. (2010). Indirect interception actions by blind and visually impaired perceivers: Echolocation for interceptive actions. Scandinavian Journal of Psychology, 51, 75–83.
This research examined the acoustic information used to support interceptive actions by the blind. Congenitally blind and severely visually impaired participants (all wearing an opaque, black eye-mask) were asked to listen to a target ball rolling down a track. In response, participants rolled their own ball along a perpendicular path to intercept the target. To better understand what information was used the echoic conditions and rolling dynamics of the target were varied across test sessions. In addition the rolling speed of the target and the distance of the participant from the target were varied across trials. Results demonstrated that participants tended to perform most accurately at moderate speeds and distances, overestimating the target's arrival at the fastest speed, and underestimating it at the slowest speed. However, changes to the target's dynamics, that is, the amount of deceleration it underwent on approach, did not strongly influence performance. Echoic conditions were found to affect performance, as participants were slightly more accurate in conditions with faster, higher-intensity echoes. Based on these results blind individuals in this research seemed to be using spatial and temporal cues to coordinate their interceptive actions. 相似文献

镶嵌图形测验、框线测验和认知偏差任务是目前国际上常用的三种场相依/场独立的测量工具。该研究发现:1)在框线测验中,个体不受背景信息干扰的能力,与整合背景信息的能力存在显著正相关关系;2)执行镶嵌图形测验愈佳者,执行框线测验的绝对任务与相对任务也愈佳;3)但认知偏差任务与镶嵌图形测验以及框线测验均无相关关系。因此,个体在感知过程中对场的利用,与其在推理决策过程中对场的利用,很可能是两个独立的心理过程。此外,由于镶嵌图形测验与智商测验有相关,框线测验可能更适合于跨文化心理学中对场相依/场独立概念的测量。 相似文献

Time perception, crucial for adaptive behavior, has been shown to be altered by emotion. An arousal-dependent mechanism is proposed to account for such an effect. Yet, physiological measure of arousal related with emotional timing is still lacking. We addressed this question using skin conductance response (SCR) in an emotion regulation paradigm. Nineteen participants estimated durations of neutral and negative sounds by comparing them to a previously memorized duration. Instructions were given to attend either to temporal or to emotional stimulus features. Attending to emotion with negative sounds generated longer subjective duration and greater physiological arousal than attending to time. However, a shared-attention condition showed discrepancy between behavioral and physiological results. Supporting the idea of a link between autonomic arousal and subjective duration, our results however suggest that this relation is not as direct as was expected. Results are discussed within recent model linking time perception, emotion and awareness. 相似文献

David Milner and Melvyn Goodale’s dissociation hypothesis is commonly taken to state that there are two functionally specialized cortical streams of visual processing originating in striate (V1) cortex: a dorsal, action‐related “unconscious” stream and a ventral, perception‐related “conscious” stream. As Milner and Goodale acknowledge, findings from blindsight studies suggest a more sophisticated picture that replaces the distinction between unconscious vision for action and conscious vision for perception with a tripartite division between unconscious vision for action, conscious vision for perception, and unconscious vision for perception. The combination excluded by the tripartite division is the possibility of conscious vision for action. But are there good grounds for concluding that there is no conscious vision for action? There is now overwhelming evidence that illusions and perceived size can have a significant effect on action ( Bruno & Franz, 2009 ; Dassonville & Bala, 2004 ; Franz & Gegenfurtner, 2008 ; McIntosh & Lashley, 2008 ). There is also suggestive evidence that any sophisticated visual behavior requires collaboration between the two visual streams at every stage of the process ( Schenk & McIntosh, 2010 ). I nonetheless want to make a case for the tripartite division between unconscious vision for action, conscious vision for perception, and unconscious vision for perception. My aim here is not to refute the evidence showing that conscious vision can affect action but rather to argue (a) that we cannot gain cognitive access to action‐guiding dorsal stream representations, and (b) that these representations do not correlate with phenomenal consciousness. This vindicates the semi‐conservative view that the dissociation hypothesis is best understood as a tripartite division. 相似文献

Gender is associated with interpersonal sensitivity across different domains, with females, on average, demonstrating higher levels of interpersonal sensitivity than males. What underlies these gender differences in the accuracy of first impressions of personality remains unclear. Across two large video studies and a large round-robin design, perceivers’ gender was related to the accuracy of general personality trait impressions. Specifically, female perceivers achieved higher levels of accuracy, but only with respect to normative accuracy or perceiving what others are like in general. There were no significant gender differences in terms of distinctive accuracy or perceiving how others are different from the average person. Discussion considers how these findings relate to previously established gender differences in other domains of interpersonal sensitivity. 相似文献

How should we assess the comparability of driving on a road and “driving” in a simulator? If similar patterns of behaviour are observed, with similar differences between individuals, then we can conclude that driving in the simulator will deliver representative results and the advantages of simulators (controlled environments, hazardous situations) can be appreciated. To evaluate a driving simulator here we compare hazard detection while driving on roads, while watching short film clips recorded from a vehicle moving through traffic, and while driving through a simulated city in a fully instrumented fixed-base simulator with a 90 degree forward view (plus mirrors) that is under the speed/direction control of the driver. In all three situations we find increased scanning by more experienced and especially professional drivers, and earlier eye fixations on hazardous objects for experienced drivers. This comparability encourages the use of simulators in drivers training and testing. 相似文献
