We examined the role of exposure duration and scene complexity on the weapon focus effect (WFE). Memory for the mock crime was affected more by a weapon than an unusual but nonthreatening object. Threat reduced correct identifications when the event was short but not long; duration of the event did not interact with unusualness. Additionally, we found a WFE for target‐absent lineup decisions, but only for the accomplice lineup, not the object‐wielding perpetrator's lineup. We discuss the implications of these results for illuminating the mechanisms that elicit the WFE. 相似文献

Smoking in movies, implicit associations of smoking with the self, and intentions to smoke 总被引:2,自引:0,他引:2
We examined whether identifying with a film character who smokes increases implicit associations of the self with smoking. Undergraduate men were randomly assigned to view film clips in which the male protagonist either smoked or did not smoke. We measured subsequent levels of self-smoking associations using a reaction time task, as well as self-reported beliefs about smoking and smokers. Greater identification with the smoking protagonist predicted stronger implicit associations between the self and smoking (for both smokers and nonsmokers) and increased intention to smoke (among the smokers). Stronger implicit self-smoking associations uniquely predicted increases in smokers' intentions to smoke, over and above the effects of explicit beliefs about smoking. The results provide evidence that exposure to smoking in movies is causally related to changes in smoking-related thoughts, that identification with protagonists is an important feature of narrative influence, and that implicit measures may be useful in predicting deliberative behavior. 相似文献

To understand better students' preferences for enrollment in distance education over face-to-face courses, the individual difference variables of sex, age category, class level, work status, number of distance education courses taken, frequency of computing technology usage, comfort with course management software, and comfort with computing technology were examined. Analysis indicated that older students, women, and those who work full time were more likely to enroll in distance education courses. Those who had taken the most distance education courses in the past and women were more likely to express a stated preference for distance education over face-to-face classes. 相似文献

Researchers have hypothesized that words that are highly related semantically are more likely to occur within the same intonational phrase (F. zzaq;, 1988; E. O. Selkirk, 1984). D. Watson and E. Gibson (2004) proposed that semantic closeness can be captured by using the argument/adjunct distinction, such that intonational boundaries are more likely to occur before adjuncts than before arguments. In the current experiment, the authors compared two aspects of argumenthood: semantic relatedness and obligatoriness. In a production study, speakers were more likely to place an intonational phrase boundary between a word and a dependent if the dependent was optional (e.g., after "investigation" in "The reporter's investigation [of the crash] unnerved the officials") than if the dependent was obligatory (e.g., after "investigated" in "The reporter investigated [the crash], and this unnerved the officials"). These data suggest that obligatoriness is a better predictor of intonational boundary placement than semantic closeness. 相似文献

All other things being equal the parser favors attaching an ambiguous modifier to the most recent possible site. A plausible explanation is that locality preferences such as this arise in the service of minimizing memory costs—more distant sentential material is more difficult to reactivate than more recent material. Note that processing any sentence requires linking each new lexical item with material in the current parse. This often involves the construction of long-distance dependencies. Under a resource-limited view of language processing, lengthy integrations should induce difficulty even in unambiguous sentences. To date there has been little direct quantitative evidence in support of this perspective. This article presents 2 self-paced reading studies, which explore the hypothesis that dependency distance is a fundamental determinant of reading complexity in unambiguous constructions in English. The evidence suggests that the difficulty associated with integrating a new input item is heavily determined by the amount of lexical material intervening between the input item and the site of its target dependents. The patterns observed here are not straightforwardly accounted for within purely experience-based models of complexity. Instead, this work supports the role of a memory bottleneck in language comprehension. This constraint arises because hierarchical linguistic relations must be recovered from a linear input stream. 相似文献

Although previous work has found associations between panic and smoking, little research has investigated potential mechanisms by which smoking may contribute to panic problems. The present investigation evaluated the incremental validity of acute nicotine withdrawal symptoms (elicited by an average of 2 h of nicotine deprivation) relative to negative affectivity, anxiety sensitivity, and nicotine dependence in predicting anxiety responding to 3-min voluntary hyperventilation. The sample consisted of 90 regular smokers (46 females), as defined by smoking 10 cigarettes per day for at least 1 year, recruited through the general community. Consistent with prediction, greater levels of pre-challenge nicotine withdrawal symptoms uniquely predicted post-challenge intensity of panic symptoms and anxiety relative to other established factors. Findings are discussed in the context of how regular smoking may promote panic symptomotology. 相似文献

Two psychophysical measures of tactile sensitivity--grating-orientation (GO) and smooth-grooved (SG) discrimination--were used to determine tactile spatial acuity with and without an intermediate surface (latex glove) interposed between the contactor and the skin. Measures were made at three locations that varied in sensitivity and in density of innervation of the primary afferent fibers: the index fingerpad (fingertip), palmar surface of the proximal phalanx (fingerbase), and the thenar eminence (palm). Neurophysiological studies have suggested that the density of innervation of SAI fibers is a limiting factor in spatial acuity. In the present study, without a glove, the GO thresholds varied as a function of location. With the glove, increases in the GO thresholds were relatively uniform and modest. Without a glove, however, the SG thresholds were well below the GO thresholds, and changing the site of stimulation had little effect on the threshold. With a glove, the SG thresholds increased by 100% to more than 300% as in comparison with those in the no-glove condition. The largest increases occurred at the less sensitive locations. The results of the GO task are consistent with the view that GO is a valid measure of spatial acuity. The results of the SG task, however, are inconsistent with previous results and suggest that both spatial and intensive factors are involved in this task. 相似文献

Four experiments investigated attachment preferences in constructions involving 3 verb phrases (VPs) followed by an attaching modifier. Readers preferred attachment to the most recent (lowest) VP site overall and preferred to attach the modifier to the middle VP over the highest VP, demonstrating a monotonic recency-based preference ordering. This pattern could not be attributed to lexical or plausibility-based preferences. The results contrast with the pattern for relative clause attachment into 3 potential noun phrase sites, where the preference ordering is nonmonotonic (e.g., E. Gibson, N. J. Pearlmutter, E. Canseco-Gonzalez, & G. Hickok, 1996), and support the multiple-constraint theory described by E. Gibson and N. J. Pearlmutter (1998), which proposes that recency/locality and a secondary factor, predicate proximity, combine with lexical, grammatical, prosodic, and contextual constraints to determine attachment preferences. 相似文献
