This study explores factors influencing international students' likelihood of using the Internet to seek disaster-related information should a disaster affect their countries. A cross-sectional survey was conducted in two universities in America between August 1 and September 30, 2005. Two hundred twenty-nine (n = 229) students completed the self-administered questionnaires. ANOVA analyses found that respondents' Internet self-efficacy had no significant impact on their intentions to seek disaster-related information on the Internet. However, respondents' Internet dependency and attitude toward seeking information online were found to have a significant effect on such intentions. 相似文献

The current research expanded upon previous theoretical and empirical arguments regarding the nature of intergroup helping. In doing so, we considered the role of relative in-group status, the stability of this status, and the type of help provided. In a scenario study, we observed that members of a relatively high status group more strongly supported the provision of assistance to in-group members than members of a lower status out-group when the assistance was empowering in nature and when the high in-group status was unstable. When the intergroup status differences were stable, however, support for empowerment help to members of a lower status out-group was not significantly lower than support for such help to in-group members. We discuss these data with reference to realistic intergroup conflict theory and social identity theory. 相似文献

We review a growing body of literature that evidences the reciprocal relationship between body and mind, known as embodied cognition. We argue that an embodied mind may serve a functional purpose, aiding in self-regulatory processes. Specifically, we suggest that embodied cognition assists in self-regulation by increasing signal strength, encouraging appropriate goal-relevant action, and incorporating situational constraints to cue appropriate information processing styles. Furthermore, we propose that affect serves as the link between an embodied mind and self-regulatory action. Finally, we situate this research in debates on theories of mind, and we advocate for a highly interactive system that integrates information across modalities. 相似文献

The central claim of this essay is that many deflationary theories of truth are variants of the correspondence theory of truth.
Essential to the correspondence theory of truth is the proposal that objective features of the world are the truthmakers of
statements. Many advocates of deflationary theories (including F. P. Ramsay, P. F. Strawson and Paul Horwich) remain committed
to this proposal. Although T-sentences (statements of the form “s is true iff p”) are presented by advocates of deflationary theories of truth as truisms or analytic truths, T-sentences are often understood
as entailing commitment to the central proposal of the correspondence theory. 相似文献

ABSTRACT— The problem of mapping differing sensory stimuli onto a common category is fundamental to human cognition. Listeners perceive stable phonetic categories despite many sources of acoustic variability. What are the neural mechanisms that underlie this perceptual stability? In this functional magnetic resonance imaging study, a short-interval habituation paradigm was used to investigate neural sensitivity to acoustic changes within and between phonetic categories. A region in the left inferior frontal sulcus showed a pattern of activation consistent with phonetic invariance: insensitivity to acoustic changes within a phonetic category and sensitivity to changes between phonetic categories. Left superior temporal regions, in contrast, showed graded sensitivity to both within- and between-category changes. These results suggest that perceptual insensitivity to changes within a phonetic category may arise from decision-related mechanisms in the left prefrontal cortex and add to a growing body of literature suggesting that the inferior prefrontal cortex plays a domain-general role in computing category representations. 相似文献

McDaniel and Einstein (2007) argued that prospective memories can be retrieved through spontaneous retrieval processes stimulated
by the presence of a target cue. To test this claim, we investigated whether presenting a prospective memory cue during a
task that did not require an intention to be performed spontaneously triggered remembering of that intention. In two experiments,
participants performed an image-rating task in which a prospective memory task (to press the “Q” key when a target word appeared)
was embedded. Then, participants were told that their intention was finished or suspended. Finally, participants performed
a lexical decision task in which each target (and a matched control) word appeared. RTs were slower to target words than to
control words when the intention was suspended but not when it was finished. These results suggest that target cues associated
with suspended intentions can spontaneously trigger remembering but that finished intentions are quickly deactivated. 相似文献

An abbreviated Spider Phobia Questionnaire (SPQ) was developed using methods based in item response theory. Fifteen of the 31 SPQ items that demonstrated good to excellent discrimination along the spider fear continuum were retained in Study 1 that consisted of 1,555 nonclinical and clinical participants. The SPQ-15 demonstrated good internal consistency and correlated highly with the full SPQ. Structural equation modeling revealed that the SPQ-15 demonstrated excellent convergent validity, with strong associations with small animal disgust and other phobic symptoms. Supportive evidence was also found for divergent validity in relation to panic-related symptoms. The SPQ-15 was uniquely predictive of avoidance behavior and fear and disgust responding towards spiders in nonclinical, analogue, and treatment-seeking samples in Studies 2, 3, and 4. Lastly, in Study 5, the SPQ-15 was sensitive to the effects of exposure-based treatment. These findings suggest that the SPQ-15 has considerable strengths, including decreased assessment and scoring time while retaining high reliability, validity, and sensitivity. 相似文献
