In face matching, observers have to decide if two photographs depict the same person or different people. This is a remarkably difficult task, so the current study investigated whether it can be improved when observers receive feedback for their performance. In five experiments, observers' initial matching performance was recorded before feedback for their accuracy was administered across three blocks. Improvements were then assessed with faces that had been seen previously with or without feedback and with completely new, previously unseen faces. In all experiments, feedback failed to improve face‐matching accuracy. However, trial‐by‐trial feedback helped to maintain accuracy at baseline level after feedback was withdrawn again, even with new faces (Experiments 1–3). By contrast, when no feedback was given throughout the experiment (Experiments 1–3) or when outcome feedback was administered at the end of blocks (Experiments 4 and 5), a continuous decline in matching accuracy was found, whereby observers found it increasingly difficult to tell different facial identities apart. A sixth experiment showed that this decline in accuracy continues throughout when the matching task is prolonged substantially. Together, these findings indicate that observers find it increasingly difficult to differentiate faces in matching tasks over time, but trial‐by‐trial feedback can help to maintain accuracy. The theoretical and practical implications of these findings are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This study addresses the issue of data combination in personnel selection. In a pilot study for the selection of trainee pilots for the German Luftwaffe, 99 applicants were assessed using a comprehensive battery of tests that measured inductive thinking, spatial thinking, attentiveness, visual and verbal short-term memory, sensorimotor coordination, and reactive stress tolerance. The global evaluation of the applicants' performance in a flight simulator served as an external criterion. The predictive validity of this test battery was checked by carrying out a discriminant analysis as well as by calculating a neural network. The 2 methods were compared with regard to their classification rate, stability, and separation of correct and incorrect classifications. The results show that artificial neural networks are useful tools for improving the quality of selection procedures for trainee pilots.  相似文献

Prayer is often an interpersonal phenomenon. It represents not only a form of social support shared between or among people, but also a means of embedding an unobservable actor (God) within a conventionally observable social network. This study considers whether the receipt of intercessory prayer from close network ties is associated with future‐oriented well‐being. Analyses use social network module data from the Portraits of American Life Study (PALS), a nationally representative study of American adults containing a breadth of information not available in prior studies of networks, prayer, and well‐being. Despite experiencing more instances of recent adversity (mental or physical health problem, financial trouble, and unemployment), prayed‐for PALS respondents report the highest levels of optimism. Furthermore, the association between network prayer and optimism is robust to inclusion of individual‐level indicators of religiosity. Finally, other forms of social support that an individual receives from his or her close ties do not explain the benefits of intercessory prayer.  相似文献

Both theoretical approaches and empirical evidence suggest that negative affect fosters analytic processing, whereas positive affect fosters holistic processing, but these effects are inconsistent. We aim to show that (a) differences in affect regulation abilities (“action orientation”) and (b) implicit more so than self‐reported affect assessment need to be considered to advance our understanding of these processes. Forty participants were asked to verify whether a word was correctly or incorrectly spelled to measure analytic processing, as well as to intuitively assess whether sets of three words were coherent (remote associates task) to measure holistic processing. As expected, implicit but not explicit negative affect interacted with low action orientation (“state orientation”) to predict higher d' performance in word spelling, whereas implicit but not explicit positive affect interacted with high action orientation to predict higher d' performance in coherence judgments for word triads. Results are interpreted according to personality systems interaction theory. These findings suggest that affect and affect changes should be measured explicitly and implicitly to investigate affect‐cognition interactions. Moreover, they suggest that good affect regulators benefit from positive affect for holistic processing, whereas bad affect regulators benefit from negative affect for analytical processing.  相似文献

Previous research has revealed affect‐congruity effects for the recognition of affects from faces. Little is known about the impact of affect on the perception of body language. The aim of the present study was to investigate the relationship of implicit (versus explicit) affectivity with the recognition of briefly presented affective body expressions. Implicit affectivity, which can be measured using indirect assessment methods, has been found to be more predictive of spontaneous physiological reactions than explicit (self‐reported) affect. Thirty‐four healthy women had to label the expression of body postures (angry, fearful, happy, or neutral) presented for 66 ms and masked by a neutral body posture in a forced‐choice format while undergoing functional magnetic resonance imaging (fMRI). Participants' implicit affectivity was assessed using the Implicit Positive and Negative Affect Test. Measures of explicit state and trait affectivity were also administered. Analysis of the fMRI data was focused on a subcortical network involved in the rapid perception of affective body expressions. Only implicit negative affect (but not explicit affect) was correlated with correct labeling performance for angry body posture. As expected, implicit negative affect was positively associated with activation of the subcortical network in response to fearful and angry expression (compared to neutral expression). Responses of the caudate nucleus to affective body expression were especially associated with its recognition. It appears that processes of rapid recognition of affects from body postures could be facilitated by an individual's implicit negative affect.  相似文献

Language acquisition is a process embedded in social routines. Despite considerable attention in research to its social nature, little is known about developmental differences in the relative priority of certain social cues over others during early word learning. Employing an eye-tracking paradigm, we presented 14-month-old infants, 24-month-old infants, and adults with movies in which an actor repeatedly gazed at one and pointed to the other of two objects while presenting them with a novel word. The results show that the 14-month-old infants pay more attention to a model's eye gaze when learning to map a novel word to a referent, whereas 24-month-old infants and adults rely more on pointing cues. Our results provide evidence for a developmental change in the relative priority of pointing versus eye-gazing cues in language acquisition.  相似文献

Family represents a primary environment for the development and transmission of gender role orientation (GRO) in adolescence. Nonetheless, longitudinal approaches delineating the separate influences of fathers and mothers, including all possible same- and cross-sex parent–child dyads within one family are lacking. This article elucidates the process of adolescent gender role socialization in 244 German families (father, mother, son and daughter) utilizing a longitudinal design (two measurement points over 5 years). Direct transmission paths of GRO and gender-specific parenting (GSP) as a mediator were analysed focusing on fathers' contributions. In addition, the impact of parental workplace autonomy and socio-economic status on intra-familial socialization of GRO was examined. Results indicate that fathers and mothers play at least an equally important role in the transmission of gender role beliefs. A mediating effect of GSP was only evident when considering father–child dyads. Based on social cognitive and developmental systems approaches, the findings are discussed considering adolescents embedded within the family context.  相似文献

Recent research suggests synesthesia as a result of a hypersensitive multimodal binding mechanism. To address the question whether multimodal integration is altered in synesthetes in general, grapheme‐colour and auditory‐visual synesthetes were investigated using speech‐related stimulation in two behavioural experiments. First, we used the McGurk illusion to test the strength and number of illusory perceptions in synesthesia. In a second step, we analysed the gain in speech perception coming from seen articulatory movements under acoustically noisy conditions. We used disyllabic nouns as stimulation and varied signal‐to‐noise ratio of the auditory stream presented concurrently to a matching video of the speaker. We hypothesized that if synesthesia is due to a general hyperbinding mechanism this group of subjects should be more susceptible to McGurk illusions and profit more from the visual information during audiovisual speech perception. The results indicate that there are differences between synesthetes and controls concerning multisensory integration – but in the opposite direction as hypothesized. Synesthetes showed a reduced number of illusions and had a reduced gain in comprehension by viewing matching articulatory movements in comparison to control subjects. Our results indicate that rather than having a hypersensitive binding mechanism, synesthetes show weaker integration of vision and audition.  相似文献

Bilingualism research has established language non-selective lexical access in comprehension. However, the evidence for such an effect in production remains sparse and its neural time-course has not yet been investigated. We demonstrate that German-English bilinguals performing a simple picture-naming task exclusively in English spontaneously access the phonological form of –unproduced– German words. Participants were asked to produce English adjective-noun sequences describing the colour and identity of familiar objects presented as line drawings. We associated adjective and picture names such that their onsets phonologically overlapped in English (e.g., green goat), in German through translation (e.g., blue flower – ‘blaue Blume’), or in neither language. As expected, phonological priming in English modulated event-related brain potentials over the frontocentral scalp region from around 440 ms after picture onset. Phonological priming in German was detectable even earlier, from 300 ms, even though German was never produced and in the absence of an interaction between language and phonological repetition priming at any point in time. Overall, these results establish the existence of non-selective access to phonological representations of the two languages in the domain of speech production.  相似文献

Benjamin Libet’s work paved the way for the neuroscientific study of free will. Other scientists have praised this research as groundbreaking. In philosophy, the reception has been more negative, often even dismissive. First, I will propose a diagnosis of this striking discrepancy. I will suggest that the experiments seem irrelevant, from the perspective of philosophy, due to the way in which they operationalize free will. In particular, I will argue that this operational definition does not capture free will properly and that it is based on a false dichotomy between internal and external causes. However, I will also suggest that this problem could be overcome, as there are no obvious obstacles to an operationalization of free will that is in accord with the philosophical conception of free will.  相似文献
