Four experiments were conducted, three with tactile stimuli and one with visual stimuli, in which subjects made temporal order judgments (TOJs). The tactile stimuli were patterns that moved laterally across the fingerpads. The subject's task was to judge which finger received the pattern first. Even though the movement was irrelevant to the task, the subjects' TOJs were greatly affected by the direction of movement of the patterns. Accuracy in judging temporal order was enhanced when the patterns moved in a direction that was consistent with the temporal order of presentation--for example, when the movement on each fingerpad was from right to left and the temporally leading site of stimulation was to the right of the temporally trailing site of stimulation. When movement was inconsistent with the temporal order of presentation, accuracy was considerably reduced, often well below chance.The bias in TOJs was unaffected by training or by presenting the stimuli to fingers on opposite hands. In a fourth experiment, subjects judged the temporal order of visual stimuli that, like the tactile stimuli, moved in a direction that was either consistent or inconsistent with the TOJ. The results were similar to those obtained with tactile stimuli. It is suggested that the bias may be affected by attentional mechanisms and by apparent motion generated between the two sites on the skin. 相似文献

Framing effects are well established: Listeners’ preferences depend on how outcomes are described to them, or framed. Less
well understood is what determines how speakers choose frames. Two experiments revealed that reference points systematically
influenced speakers’ choices between logically equivalent frames. For example, speakers tended to describe a 4-ounce cup filled
to the 2-ounce line as half full if it was previously empty but described it as half empty if it was previously full. Similar
results were found when speakers could describe the outcome of a medical treatment in terms of either mortality or survival
(e.g., 25% die vs. 75% survive). Two additional experiments showed that listeners made accurate inferences about speakers’
reference points on the basis of the selected frame (e.g., if a speaker described a cup as half empty, listeners inferred
that the cup used to be full). Taken together, the data suggest that frames reliably convey implicit information in addition
to their explicit content, which helps explain why framing effects are so robust. 相似文献

We investigated the neural bases for false memory with fMRI by examining neural activity during retrieval processes that yielded true or false memories. We used a reality monitoring paradigm in which participants saw or imagined pictures of concrete objects. (A subsequent misinformation task was also used to increase false memory rates.) At test, fMRI data were collected as the participants determined whether they had seen or had only imagined the object at study. True memories were of seen pictures accurately endorsed as seen, and for false memories were of imagined pictures falsely endorsed as seen. Three distinct patterns of activity were observed: Left frontal and parietal activity was not different for true and for false memories, whereas activity was greater for true than for false memories in occipital visual regions and posterior portions of the parahippocampal gyrus, and activity was greater for false than for true memories in right anterior cingulate gyrus. Possible interpretations are discussed. 相似文献

The psychological needs derived from the Adjective Check List (ACL; Gough & Heilbrun, 1983b) that are associated with MMPI-2 scales were studied among 198 nonclinical participants. Both the Depression (D) and Psychasthenia (Pt) scales were negatively correlated with needs for achievement and dominance and positively correlated with needs for abasement and succorance (dependence). The Schizophrenia (Sc) scale was negatively associated with need for affiliation and positively associated with need for abasement. The Social Introversion (Si) scale was associated negatively with needs for achievement, dominance, affiliation, heterosexuality, exhibition, and autonomy and associated positively with needs for succorance, abasement, and deference, reflecting good construct validity for Scale Si. MMPI-2 Masculinity-Femininity (Mf) did not correlate with the ACL Masculinity and Femininity scales, suggesting poor concurrent validity for Mf. 相似文献

According to attributional theories of emotion, feelings of guilt presuppose that the causes of a negative event are located within the individual (internal attribution), whereas feelings of anger presuppose that the causes of the eliciting event are located outside the individual (external attribution). This study tested whether these attributions in fact exert the claimed causal influence on emotional experiences. The study employed a procedural priming technique in which neutral events were repeatedly attributed either to oneself (internal attribution) or to another person (external attribution). Subsequently, participants were exposed to a negative event that was ambiguous as to its causes. The results reveal that the prior repeated use of internal attributions enhanced the tendency to experience guilt, whereas the repeated use of external attributions enhanced the tendency to experience anger. These findings support the assumption that attributions exert a causal influence on emotions. 相似文献

Conclusion Newcomb's Paradox thus serves as an illustrative vindication of the compatibility of divine foreknowledge and human freedom.
A proper understanding of the counterfactual conditionals involved enables us to see that the pastness of God's knowledge
serves neither to make God's beliefs counterfactually closed nor to rob us of genuine freedom. It is evident that our decisions
determine God's past beliefs about those decisions and do so without invoking an objectionable backward causation. It is also
clear that in the context of foreknowledge, backtracking counterfactuals are entirely appropriate and that no alteration of
the past occurs. With the justification of the one box strategy, the death of theological fatalism seems ensured. *** DIRECT

Pica is a severe behavior disorder involving the persistent consumption of nonnutritive substances. Due to health complications and risks for fatality, designing effective behavioral treatments that are feasible for implementation by family members at home is imperative. This case report presents a parent-conducted functional analysis and treatment evaluation of automatically maintained pica in a teenager with autism spectrum disorder. Initial treatment with a competing stimulus was effective when paired with response interruption and redirection. Although effective, this combination of treatment components required very close parental proximity and led to increases in untargeted body-oriented pica (e.g., ingestion of skin, hair, and nails). Upon extending treatment to include the second topography of pica, both the originally targeted (object-oriented) pica and body-oriented pica decreased. Nonetheless, treatment effects were not sustained while fading parent proximity. The treatment was then augmented a third time with response cost. This final treatment package produced clinically significant reductions in all pica, facilitated parent proximity fading until the participant was alone, extended to their home, and maintained over a year of follow up. 相似文献
