Attributions are shaped by information about the causal mechanisms that produce outcomes. Two studies examined the effect of mechanism information on attributions for earthquake damage and judgments that the damage could be prevented. Scenarios based on actual reports of earthquakes compared 2 messages about the building design of damaged buildings. Accurate rate‐based messages stated that well‐designed buildings were resilient, whereas fatalistic, instance‐based messages stated that well‐designed buildings were damaged. In Study 2, to vary source credibility, the message source was either an engineer or a reporter. Participants made less fatalistic inferences and attributions with rate‐based messages than with instance‐based messages, regardless of the source. These findings show that rate‐based messages are likely to reduce fatalism about earthquakes and other risks. 相似文献

The medial prefrontal cortex (MPFC) reliably activates in social cognition and reward tasks. This study locates distinct areas
for each. Participants made evaluative (positive/negative) or social (person/not a person) judgments of pictured positive
or negative people and objects in a slow event-related design. Activity in an anterior rostral region (arMPFC) was significantly
greater for positive than for negative persons but did not show a valence effect for objects, and this was true regardless
of the judgment task. This suggests that the arMPFC is tuned to social valence. Interestingly, however, no regions of the
MPFC were found to be responsive to social information independently of valence. A region-of-interest analysis of the paraanterior
cingulate cortex (pACC), previously implicated in reward processing, demonstrated sensitivity to the valence of all stimuli,
whether persons or objects, across tasks. Affective evaluation may be a general function of the MPFC, with some regions being
tuned to more specific domains of information (e.g., social) than are others. 相似文献

The pituitary-adrenal system is thought to be sensitive to the degree of uncertainty in a situation. In addition, there is some question whether the pituitary-adrenal system can be conditioned in a Pavlovian sense. Three experiments are reported here. The first and third sought to define uncertainty in terms of conditioned stimulus-unconditioned stimulus (CB-US) and US-US contingencies, which vary the amount of information that can be used to predict the occurrence of discrete shocks. The second experiment examined the possibility that the adrenocortical system was subject to the laws of Pavlovian conditioning, by using a conditioned emotional response paradigm. The results showed that the magnitude of the Pituitary-adrenal response varied in a curvilinear manner along the dimension of uncertainty. Very low and very high degrees of uncertainty resulted in greater corticosterone elevations than did moderate levels. No evidence for Pavlovian conditioning of the adrencortical system was found, although behavioral measures showed fear conditioning. The data presented were supportive of the hypothesis that the pituitary-adrenal response reflects the operation of an arousal system. 相似文献

In recent studies, various regions of the ventral medial prefrontal cortex (vmPFC) have been implicated in at least two potentially
different mental functions: reasoning about the minds of other people (social cognition) and processing reward related information
(affective evaluation). In this study, we test whether the activation in a specific area of the vmPFC, the para-anterior cingulate
cortex (PACC), correlates with the reward value of stimuli in general or is specifically associated with social cognition.
Participants performed a time estimation task with trial-to-trial feedback in which reward and social context were manipulated
separately. Reward was manipulated by giving either positive or negative feedback in the form of small squirts of fluid delivered
orally. Social context was manipulated by instructing participants that positive and negative feedback was determined by another
person or a computer. The data demonstrate a main effect of feedback, but not social context, in the PACC, suggesting that
this area of the vmPFC serves a general function in evaluating and/or representing reward value. In addition, activity in
a more anterior subregion of the vmPFC demonstrated reward-related sensitivity only in the social context. Another area that
showed a similar interaction was the subgenual cingulate, but this region was only sensitive to negative feedback in the social
condition. These findings suggest that, within the vmPFC, the PACC subserves primarily an affective function, whereas in other
regions social context can modulate affective responses. 相似文献

The aim of the present study was to clarify the mechanisms underlying body understanding by examining the impact of visual experience (magnification and reduction) on perception of hand size and neutral external objects (squares). Independent groups of participants were asked to look through a 2× magnification lens, a ½-× reduction lens, or a control UV filter and to make visual size judgments about square stimuli and their hands. In Experiment 1, participants used a measuring device with unmarked wooden slats orientated in horizontal and radial/vertical space for their visual judgments. In Experiment 2, participants used an upright frontal slat for visual length judgments of their hands to eliminate any potential foreshortening in viewing the measurement apparatus. The results from the two experiments demonstrate that participants significantly underestimated both the square stimuli and their hands when they viewed them under a reduction lens. While overestimation and underestimation of squares was found for females in Experiment 2, males generally underestimated the squares. However, overestimation was not seen when the participants viewed their hands under a magnification lens. Implications of these findings are discussed. 相似文献

According to difference-based (e.g. counterfactual/covariational) models of causal judgement, the epistemic state of the agent should not affect judgements of cause. Four experiments examined opportunity chains in which a physical event (distal cause) enabled a subsequent proximal cause to produce an outcome. All four experiments showed that when the proximal cause was a human action, it was judged as more causal if the agent was aware of his opportunity than if he was not or if the proximal cause was a physical event. The first two experiments showed that these preferences could not be explained in terms of differences in perceived conditional probability (whether from the observer's or the agent's point of view), social controllability or perceptions of the causal sequence as forming a single unit. The third experiment showed that awareness affected the perceived deliberateness with which the action brought the outcome about but not its perceived voluntariness. The fourth experiment showed that when the outcome was intended, the perceived deliberateness of the agent's action was a plausible mediator of the effect of awareness of opportunity on causal preference. We conclude that awareness of the opportunity allows inferences about the deliberate production of the outcome when the action is voluntary, which in turn influence causal judgements. 相似文献

During the course of a criminal investigation witness vetting, a detective's process of determining the credibility and weight of witness information, can lead to errors in an investigation that can go virtually unchallenged. Witness confidence, opportunity to view, and type of information proffered were examined in relation to detective inferences about witness reliability, accuracy, and probable cause to arrest. Experiment 1 involved 39 sworn law enforcement officers, and experiment 2 involved 43 sworn law enforcement officers and 86 mock detectives. Participants viewed a digital recording depicting a witness describing a gas station robbery (Experiment 1) or a campus mugging (Experiment 2). Witness confidence and detectives' inferences about culprit information influenced the vetting process and lent credibility to a confident witness whose accuracy was objectively unknown. Furthermore, the evidence indicates that sworn law enforcement are comparable with untrained observers in their use of social inference cues (i.e. confidence) in determining witness credibility; however, social inference can be assuaged by the rational, rule‐governed, decision framework established for witness vetting. Social inference processes inherent in the detective‐witness dyad is influenced by legal procedures in vetting witness information. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Sometimes children die from maltreatment. However, when first responders enter a scene to save the life of a dying child, the cause of the health problem cannot be immediately determined. EMS professionals are taught to enact the medically appropriate protocols in a family-centered way. This study examines five case studies of infant deaths. When there is ambiguity as to why the death might have occurred, EMS and other emergency personnel seem to be more judgmental and this attitude affects their behavior toward family members. Family members have a more difficult time coping with the loss as a result. 相似文献

Aversive symptoms of abstinence from nicotine have been posited to lead to smoking relapse and research on temporal patterns of abstinence symptoms confirms this assumption. However, little is known about the association of symptom trajectories early after quitting with postcessation smoking or about the differential effects of tonic (background) versus phasic (temptation-related) symptom trajectories on smoking status. The current study examined trajectories of urge and negative mood among 300 women using the nicotine patch during the first postcessation week. Ecological momentary assessments collected randomly and during temptation episodes were analyzed using hierarchical linear modeling yielding four individual trajectory parameters: intercept (initial symptom level), linear slope (direction and rate of change), quadratic coefficient (curvature), and volatility (scatter). Early lapsers, who lapsed during the first postcessation week, exhibited more severe tonic urge and phasic negative mood immediately after quitting, and more volatile tonic and phasic urge compared to abstainers. Late lapsers, who were abstinent during the first week but lapsed by 1 month, exhibited more severe tonic urge immediately after quitting compared to abstainers. These results demonstrate the importance of early postcessation urge and negative affect and highlight the value of examining both tonic and phasic effects of abstinence from nicotine. 相似文献
