Previous researchers found that individuals with intellectual and developmental disabilities tend to prefer edible over leisure stimuli, although leisure stimuli may still function as reinforcers. We replicated and extended previous research in a 2-part experiment with typically developing children. In Experiment 1, we evaluated 15 children's preference for leisure and edible stimuli. Five of 15 participants preferred edible over leisure stimuli, 3 of 15 participants preferred leisure over edible stimuli, and the remaining 7 of 15 participants did not show a preference for a stimulus class. In Experiment 2, we compared the reinforcer potency of the top-ranked stimulus from each class with 7 of the 8 participants who showed displacement of one stimulus class. Four of 7 participants allocated more responding to the task associated with the top-ranked stimulus and 3 of 7 participants showed no differences in responding to the task regardless of the stimulus rank. 相似文献

Engaging in risky behaviors is a sexual signalling strategy that men use to procure mates. The present study investigates men’s preferences for engaging in risky behaviors (along with women’s preferences for their male partner’s risky behavior) within dating couples. We investigated associations between relationship length, self-perceived attractiveness, sociosexuality orientation, and preference for risky behaviors in a sample of 256 couples. Results indicated that men had stronger preferences for risky behaviors than their partner’s ideal preference. Furthermore, relationship length was associated with a decline in women’s preference for their partner’s risk-taking, but not men’s preference for their own risk-taking. Self-perceived attractiveness was negatively associated with risk preference, and sociosexuality orientation was not directly related to risk preference. Female preferences for less intense male risky behaviors could reflect the need of paternal investment which is required for offspring care. Decreased male sexual signalling could account for lower preferences of risky behaviors in females who are involved in longer lasting romantic relationships. 相似文献

Two studies provide support for the group‐justification approach to stereotyping (Tajfel, 1981 ; Huici, 1984 ). This approach contends that stereotypes not only serve cognitive functions for individuals but also provide a means of justifying prior intergroup discrimination. Study 1 investigated whether the content of the Scottish ingroup stereotype changes due to the prior expression of intergroup discrimination. Scottish students were primed with either a ‘differentiation’ or a ‘fairness’ ingroup norm and completed two intergroup judgement tasks. Other Scottish students were primed only with a ‘differentiation’ ingroup norm, while a control group received no prime or judgement tasks. Only participants who experienced the ‘differentiation’ ingroup norm prime and the intergroup judgement tasks changed the content of their ingroup stereotype as an attempt to justify their discriminatory behaviour. Study 2 examined whether Scottish students would use both positive ingroup and negative outgroup stereotypes to rationalize intergroup discrimination. Students who experienced a ‘differentiation’ ingroup norm prime and intergroup judgement tasks showed the highest level of superior recall for positive ingroup and negative outgroup stereotype‐consistent words compared to stereotype‐neutral words. This finding suggests that the expression of intergroup discrimination activates the use of both positive ingroup and negative outgroup stereotypes. Together the findings of these two studies provide empirical support for the notion that stereotypes serve social as well as cognitive functions. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Three studies examined the notion that computer‐mediated communication (CMC) can be characterised by high levels of self‐disclosure. In Study One, significantly higher levels of spontaneous self‐disclosure were found in computer‐mediated compared to face‐to‐face discussions. Study Two examined the role of visual anonymity in encouraging self‐disclosure during CMC. Visually anonymous participants disclosed significantly more information about themselves than non‐visually anonymous participants. In Study Three, private and public self‐awareness were independently manipulated, using video‐conferencing cameras and accountability cues, to create a 2 × 2 design public self‐awareness (high and low)×private self‐awareness (high and low). It was found that heightened private self‐awareness, when combined with reduced public self‐awareness, was associated with significantly higher levels of spontaneous self‐disclosure during computer‐mediated communication.

This study evaluated whether a diminished perception of control over environmental and interoceptive events differentially predicted interpretive biases for threat for ambiguous scenarios. The sample had 95 participants without a history of psychopathology. Results indicated that the internal dimension of the Anxiety Control Questionnaire (ACQ; R. M. Rapee, M. G. Craske, T. A. Brown, & D. H. Barlow, 1996) was predictive of interpretive biases for internal scenarios above and beyond demographic variables, subclinical panic attack history, and state anxiety; the external control subscale of the ACQ also was predictive of internal rank-ordered responses. The ACQ external dimension was predictive of interpretive responses for external scenarios beyond the effects accounted for by the other predictor variables, including perceived control for internal events. These findings provide initial correlational evidence consistent with cognitive–behavioral accounts of panic disorder that posit a perceived lack of control over aversive events may exacerbate an interpretive bias for threat. 相似文献

Chronic Fatigue Syndrome (CFS) is an illness that involves severe, prolonged fatigue as well as neurological, immunological, and endocrinological system pathology. Because the pathogenesis of CFS has yet to be determined, case definitions have relied on clinical observation in classifying signs and symptoms for diagnosis. In an attempt to address various criticisms and inconsistencies in diagnostic criteria, there have been several revisions of the CFS case definition. The current investigation examined the differences between 1988 and 1994 definitions as well as participants who had a psychiatric explanation for their fatigue. Dependent measures included psychiatric comorbidity, symptom frequency, and functional impairment. The 1988 criteria, compared to the 1994 criteria, appeared to select a group of participants with more symptomatology and functional impairment, but these groups did not significantly differ in psychiatric comorbidity. Implications of these findings are discussed. 相似文献

This article offers an explanation for the proposed moral asymmetry between non‐responsible threats and innocent bystanders. Some argue that a non‐responsible threat – a person who threatens another through no fault or choice – is required to bear a greater burden to avert the threat than a bystander. I argue that previous attempts to explain this asymmetry are either incorrect or incomplete, since they either implausibly suggest that agents who do not benefit from their bodily resources, or whose bodily resources primarily benefit third parties, are liable to greater costs than a bystander, or fail to accommodate such cases. Instead, the asymmetry (when it exists) is explained either by virtue of the fact that the non‐responsible threat has a beneficiary status with respect to the threatening object, or possesses distribution‐limiting entitlements over the threatening object. 相似文献

Why are disembodied extraordinary beings like gods and spirits prevalent in past and present theologies? Under the intuitive Cartesian dualism hypothesis, this is because it is natural to conceptualize of minds as separate from bodies; under the counterintuitiveness hypothesis, this is because beliefs in minds without bodies are unnatural—such beliefs violate core knowledge intuitions about person physicality and consequently have a social transmission advantage. We report on a critical test of these contrasting hypotheses. Prior research found that among adult Christian religious adherents, intuitions about person psychology coexist and interfere with theological conceptualizations of God (e.g., infallibility). Here, we use a sentence verification paradigm where participants are asked to evaluate as true or false statements on which core knowledge intuitions about person physicality and psychology and Christian theology about God are inconsistent (true on one and false on the other) versus consistent (both true or both false). We find, as predicted by the counterintuitiveness hypothesis but not the Cartesian dualism hypothesis, that Christian religious adherents show worse performance (lower accuracy and slower response time) on statements where Christian theological doctrines about God's physicality (e.g., incorporeality, omnipresence) conflict with intuitions about person physicality. We find these effects for other extraordinary beings in Christianity—the Holy Spirit and Jesus—but not for an ordinary being (priest). We conclude that it is unintuitive to conceptualize extraordinary beings as disembodied, and that this, rather than inherent Cartesian dualism, may explain the prevalence of beliefs in such beings. 相似文献
