Matching unfamiliar faces is highly error‐prone, and most studies highlight the implications for real‐world ID‐checking. Here we study a particular instance of ID‐checking: proof of age for buying restricted goods such as alcohol. In this case, checkers must establish that an identity document is carried by its legitimate owner (i.e., that the ID photo matches the face of the bearer) and that the ID proves the bearer to be old enough to make the purchase. Across three experiments, using two common forms of photo‐ID (i.e., driving licenses, PASS+ cards) we show that observers produce very high error rates when age requirements are met, but faces mismatch. This bias away from detecting a face mismatch remained evident in experienced cashiers—though to a somewhat attenuated level. We discuss interactions between face matching and other tasks, and the practical consequences of a bias which favours those using photo‐ID with fraudulent intent. 相似文献

Well-known literature reviews from the 1960s question whether cognitive dissonance underlies experimental participants' selective exposure of themselves to consonant messages and avoidance of dissonant ones. A meta-analytic review of 16 studies published from 1956 to 1996 and involving 1,922 total participants shows that experimental tests consistently support the supposition that dissonance is associated with selective exposure (r = .22, p < .001). Statistical power exceeded .99. Advances in statistical methodology and increased attention to selecting appropriate tests of dissonance theory were essential to finally resolving this question. 相似文献

Synesthetic color experiences influence memory 总被引:2,自引:0,他引:2
We describe the extraordinary memory of C, a 21–year–old student who experiences synesthetic colors (i.e., photisms) when she sees, hears, or thinks of digits. Using three matrices of 50 digits, we tested C and 7 nonsynesthetes to evaluate whether C's synesthetic photisms influence her memory for digits. One matrix consisted of black digits, whereas the other two matrices consisted of digits that were either incongruent or congruent with the colors of C's photisms. C's recall of the incongruently colored digits was considerably poorer than her recall of either the black or the congruently colored digits. The 7 nonsynesthetes did not show such differences in their recall of the matrices. In addition, when immediate recall of the black digits was compared with delayed recall of those digits (48 hr), C showed no decrease in performance, whereas each of the nonsynesthetes showed a significant decrease. These findings both demonstrate C's extraordinary memory and show that her synesthetic photisms can influence her memory for digits. 相似文献

This study compared Rorschach records of nondissociative outpatients with histories of (a) definite sexual abuse (n = 22), (b) suspected but unconfirmed sexual abuse (n = 13), or (c) no sexual abuse (n = 43) on selected variables hypothesized to be associated with sexual abuse. As predicted, clients with definite sexual abuse scored significantly higher than clients known not to be sexually abused on Armstrong and Loewenstein's (1990) Trauma Content index (TC/R), with an effect size greater than 1 SD. Contrary to prediction, there was no significant difference in the frequency of their Aggressive Past (AgPast; Gacono & Meloy, 1994) scores. AgPast scores, however, did positively correlate with sexual abuse that was violent or sadistic. As a test of discriminant validity, we hypothesized that 2 Rorschach variables (PER and Sc) would be unrelated to sexual abuse. This was supported by our data. Although TC/R was strongly associated with the presence and severity of sexual abuse, it could not discriminate sexually abused from nonsexually abused clients with great accuracy. The TC/R score is 1 factor among many that can be used to assess the validity of clients' claims of past sexual abuse. 相似文献

Neuropsychologists are asked frequently to address the issue of the cause of a variety of central nervous system problems that may affect higher cortical function. One such issue is the relationship of maternal smoking to adverse reproductive outcomes involving neocortical insult including mental retardation, learning disabilities, attention-deficit hyperactivity disorder, and other insults that may be related to prolonged hypoxic states in utero. The instant paper develops the issue of causation as a scientific inquiry, reviews several traditional, applicable models, and critiques these models. An additional model of motility is proposed and discussed. The issue of the relationship of maternal smoking to adverse reproductive outcomes is then addressed from a review perspective along with new empirical analyses, the latter demonstrating that researchers tend to draw causal conclusions independent of whether the respective design of their studies would support conclusions about the causation of an event. Causal conclusions in the absence of causal designs have often lead to incomplete and incorrect conclusions. It is necessary to match conclusions not only to the outcomes of a research project but also to its design and accompanying limitations. 相似文献

Covert face recognition in neurologically intact participants 总被引:1,自引:0,他引:1
Prosopagnosic patients may maintain some ability to recognize familiar faces, although they remain unaware of this ability.
This phenomenon – called covert face recognition – was investigated in neurologically intact participants, using priming techniques.
Participants were quicker to indicate that a target-name was familiar when the preceding prime-face belonged to the same person
compared with an unrelated familiar person. This was observed both when prime-faces could be recognized overtly and when they
were presented too briefly to be recognized overtly (Exps. 1 and 2). Thus, covert face recognition was observed in neurologically
intact participants. In Exp. 3, participants were quicker to recognize a familiar face when that person's face had been seen
previously, but only when it had been recognized overtly on the first encounter. These results are interpreted within the
framework of an interactive activation model of face recognition.

Heterogeneity in the longitudinal course of depressive symptoms was studied through the use of general growth mixture modeling for young men in the Oregon Youth Study (N=206), who ranged in age from 15 to 24 years. Four trajectory classes were identified: the very-low, the moderate-decreasing, the high-decreasing, and the high-persistent classes. The 3 lowest classes differed primarily quantitatively with the initial level or mean level across time being the major determinant of class differences, whereas the high-persistent class appeared qualitatively different in terms of long-term developmental trends and variation. Findings from univariate and multivariate analyses revealed specific effects of childhood, parental, contextual, and individual risk factors on the class membership as well as on the growth within each trajectory class. 相似文献

The authors designed the present study to examine the association between individuals' scores on the Jefferson Scale of Physician Empathy (JSPE; M. Hojat, J. S. Gonnella, S. Mangione, T. J. Nasca, & M. Magee, 2003; M. Hojat, J. S. Gonnella, T. J. Nasca, S. Mangione, M. Vergare, & M. Magee, 2002; M. Hojat, S. Mangione, T. J. Nasca, M. J. M. Cohen, J. S. Gonnella, J. B. Erdmann, J. J. Veloski, & M. Magee, 2001), a self-report empathy scale, during medical school and ratings of their empathic behavior made by directors of their residency training programs 3 years later. Participants were 106 physicians. The authors examined the relationships between scores on the JSPE (with 20 Likert-type items) at the beginning of the students' 3rd year of medical school and ratings of their empathic behavior made by directors of their residency training programs. Top scorers on the JSPE in medical school, compared to Bottom scorers, obtained a significantly higher average rating of empathic behavior in residency 3 years later (p < .05, effect size = 0.50). The findings support the long-term predictive validity of the self-report empathy scale, JSPE, despite different methods of evaluations (self-report and supervisors' ratings) and despite a time interval between evaluations (3 years). Because empathy is relevant to prosocial and helping behavior, it is important for investigators to further enhance our understanding of its correlates and outcomes among health professionals. 相似文献

Computer-generated shapes varying on visual dimensions such as curvature, tapering, and thickness have been used to investigate identification deficits in the category-specific visual agnosia (CSVA) Patient E.L.M.. However, whether the implemented variations on each of these dimensions were perceived by novice observers as "similar amounts of change" is unknown. To estimate distance in psychophysical shape space, sets of shapes were developed using two different scaling methods--an objective method based on visual search, and a subjective method based on judgments of similarity--and a third approach that did not involve scaling. How well each method estimated psychophysical shape space was assessed by measuring the confusions within memory among the shapes. The results suggested that, although neither of the approaches perfectly reflected psychophysical shape space, subjective scaling was a better estimator of distance in psychophysical shape space than were other approaches. The number of confusions produced on each set of shapes was used to develop a new set of shapes that accurately estimated distance in psychophysical shape space. These results suggest that a combination of approaches is preferable in order to accurately estimate distance in psychophysical shape space. 相似文献

Two experiments are reported in which subjects made judgments about the sex or the familiarity of a voice. In experiment 1, subjects were fans of the BBC-radio soap opera, The Archers, and familiar voice clips were taken from this programme. Subjects showed a large reduction in response times when making sex judgments to familiar voices, despite the fact that sex judgments are generally much faster than familiarity judgments. In experiment 2, the same familiar clips were played to subjects unfamiliar with the soap opera, and no difference was observed in times to make sex judgments to Archers or non-Archers voices. We conclude that, unlike the case of face recognition, sex and identity processing of voices are not independent. The findings constrain models of person recognition across multiple modalities. 相似文献
