Three experiments are reported which examined the capacity to match a voice with a static image of a face. When using a simultaneous same/different matching task, performance was significantly better than chance (Experiments 1 and 2). However, it did not appear to depend either on sex of speaker, sex of listener, stimulus distinctiveness, or self-reported strategies (Experiment 2). Concerns over floor effects as well as a significant response bias prompted a change of task, and when performance was examined through matching a voice to a face lineup, a more interesting pattern emerged. Again, performance was significantly better than chance, but in addition, it was demonstrably affected by the distinctiveness of the speaker’s voice. These results are considered in the context of theoretical discussions regarding face–voice integration, and in the context of more applied considerations regarding multimodal benefits in witness scenarios. 相似文献

Recent converging evidence suggests that language and vision interact immediately in non-trivial ways, although the exact nature of this interaction is still unclear. Not only does linguistic information influence visual perception in real-time, but visual information also influences language comprehension in real-time. For example, in visual search tasks, incremental spoken delivery of the target features (e.g., “Is there a red vertical?”) can increase the efficiency of conjunction search because only one feature is heard at a time. Moreover, in spoken word recognition tasks, the visual presence of an object whose name is similar to the word being spoken (e.g., a candle present when instructed to “pick up the candy”) can alter the process of comprehension. Dense sampling methods, such as eye-tracking and reach-tracking, richly illustrate the nature of this interaction, providing a semi-continuous measure of the temporal dynamics of individual behavioral responses. We review a variety of studies that demonstrate how these methods are particularly promising in further elucidating the dynamic competition that takes place between underlying linguistic and visual representations in multimodal contexts, and we conclude with a discussion of the consequences that these findings have for theories of embodied cognition. 相似文献

Being able to wait is an essential part of self-regulation. In the present study, the authors examined the developmental course of changes in the latency to and duration of target-waiting behaviors by following 65 boys and 55 girls from rural and semirural economically strained homes from ages 18 months to 48 months. Age-related changes in latency to and duration of children's anger expressions and attention focus (e.g., self-initiated distraction) during an 8-min wait for a gift were found. On average, at 18 and 24 months of age, children were quick to react angrily and slower to shift attention away from the desired object than they were at later ages. Over time, children were quicker to distract themselves. By 36 months, distractions occurred before children expressed anger, and anger expressions were briefer. At 48 months, children typically made a quick bid to their mothers about having to wait before distracting themselves; on average, they did not appear angry until the latter half of the wait. Unexpectedly, children bid to their mothers as much at age 48 months as they had at 18 months; however, bids became less angry as children got older. Developmental changes in distraction and bidding predicted age-related changes in the latency to anger. Findings are discussed in terms of the neurocognitive control of attention around age 30 months, the limitations of children's self-regulatory efforts at age 48 months, and the importance of fostering children's ability to forestall, as well as modulate, anger. 相似文献

The dramatic rise in the diagnosis of autism spectrum disorders (ASDs) has resulted in a significant explosion in visibility
and a substantial increase in the understanding of this complex group of disorders. Over the last decade, what was once defined
only as “autism” has become a spectrum of neurodevelopmental disorders, with variable presentations and levels of impairment
that requires an equally broad continuum of care. A wealth of research has not discovered a single “cause” for ASDs, but rather
has found a range of genetic/genomic variations that likely play a significant role in the etiology of these disorders. Routine
screening for autism is becoming more common, allowing for more timely diagnosis, and hopefully for earlier entry into appropriate
and effective treatment. Although there remains no single ‘‘cure’’, there are treatments available that can improve overall
functioning and decrease problematic or interfering symptoms across the full spectrum of this disorder. The wide spectrum
of ASD presentations complicates treatment planning, with overall ASD severity a factor in determining type, intensity, and
duration of interventions and services. This article presents a two-dimensional model of “ASD severity” that considers both
the level of specific ASD symptoms/deficits and the level of cognitive resources/limitations as a framework for understanding
needs, challenges, and potentially effective interventions for individuals across the ASD spectrum. 相似文献

The relationship between religious obligations and female genital cutting is explored using data from Burkina Faso, a religiously and ethnically diverse country where approximately three-quarters of adult women are circumcised. Data from the 2003 Burkina Faso Demographic and Health Survey are used to estimate multilevel models of religious variation in the intergenerational transmission of female genital cutting. Differences between Christians, Muslims, and adherents of traditional religions are reported, along with an assessment of the extent to which individual and community characteristics account for religious differences. Religious variation in the intergenerational transmission of female genital cutting is largely explained by specific religious beliefs and by contextual rather than individual characteristics. Although Muslim women are more likely to have their daughters circumcised, the findings suggest the importance of a collective rather than individual Muslim identity for the continuation of the practice. 相似文献

We evaluated the effects of feedback and instruction on resident physician performance during developmental surveillance of infants at 2-month preventive care visits. Baseline data were obtained by videotaping 3 residents while they performed the physical and developmental exam components. Training consisted of individualized feedback and a brief instructional module, after which the residents were again videotaped while they performed preventive care visits. All 3 residents showed improved performance following training. 相似文献

Can false memories have a positive consequence on human cognition? In two experiments, we investigated whether false memories could prime insight problem-solving tasks. Children and adults were asked to solve compound remote associate task (CRAT) problems, half of which had been primed by the presentation of Deese/Roediger-McDermott (DRM) lists whose critical lures were also the solutions to the problems. In Experiment 1, the results showed that regardless of age, when the critical lure was falsely recalled, CRAT problems were solved more often and significantly faster than problems that were not primed by a DRM list. When the critical lure was not falsely recalled, CRAT problem solution rates and times were no different from when there was no DRM priming. In Experiment 2, without an intervening recall test, children and adults still exhibited higher solution rates and faster solution times to CRAT problems that were primed than to those that were not primed. This latter result shows that priming occurred as a result of false memory generation at encoding and not at retrieval during the recall test. Together, these findings demonstrate that when false memories are generated at encoding, they can prime solutions to insight-based problems in both children and adults. 相似文献

Being ostracized can be a painful and distressing experience and can lead to subsequent aggression by the victim. However, it is unknown whether watching someone else be ostracized either in real life or on television is similarly distressing. The purpose of the current study was to examine what type of distress (if any) is induced after viewing ostracism on television. The study consisted of 50 participants, half who viewed a movie clip containing ostracism and half who viewed a control clip. Physiological and self-report data revealed that viewing ostracism was distressing to participants. In particular, participants who viewed the ostracism clip reported a lower sense of belonging, self esteem, and mood, and a greater increase in heart rate and skin conductivity than those who viewed the control clip. 相似文献

It has long been understood that food deliveries may act as signals of future food location, and not only as strengtheners of prefood responding as the law of effect suggests. Recent research has taken this idea further—the main effect of food deliveries, or other “reinforcers”, may be signaling rather than strengthening. The present experiment investigated the ability of food deliveries to signal food contingencies across time after food. In Phase 1, the next food delivery was always equally likely to be arranged for a left‐ or a right‐key response. Conditions were arranged such that the next food delivery was likely to occur either sooner on the left (or right) key, or sooner on the just‐productive (or not‐just‐productive) key. In Phase 2, similar contingencies were arranged, but the last‐food location was signaled by a red keylight. Preference, measured in 2‐s bins across interfood intervals, was jointly controlled by the likely time and location of the next food delivery. In Phase 1, when any food delivery signaled a likely sooner next food delivery on a particular key, postfood preference was strongly toward that key, and moved toward the other key across the interreinforcer interval. In other conditions in which food delivery on the two keys signaled different subsequent contingencies, postfood preference was less extreme, and quickly moved toward indifference. In Phase 2, in all three conditions, initial preference was strongly toward the likely‐sooner food key, and moved to the other key across the interfood interval. In both phases, at a more extended level of analysis, sequences of same‐key food deliveries caused a small increase in preference for the just‐productive key, suggesting the presence of a “reinforcement effect”, albeit one that was very small. 相似文献

Many studies have examined the accuracy of predictions of future memory performance solicited through judgments of learning (JOLs). Among the most robust findings in this literature is that delaying predictions serves to substantially increase the relative accuracy of JOLs compared with soliciting JOLs immediately after study, a finding termed the delayed JOL effect. The meta-analyses reported in the current study examined the predominant theoretical accounts as well as potential moderators of the delayed JOL effect. The first meta-analysis examined the relative accuracy of delayed compared with immediate JOLs across 4,554 participants (112 effect sizes) through gamma correlations between JOLs and memory accuracy. Those data showed that delaying JOLs leads to robust benefits to relative accuracy (g = 0.93). The second meta-analysis examined memory performance for delayed compared with immediate JOLs across 3,807 participants (98 effect sizes). Those data showed that delayed JOLs result in a modest but reliable benefit for memory performance relative to immediate JOLs (g = 0.08). Findings from these meta-analyses are well accommodated by theories suggesting that delayed JOL accuracy reflects access to more diagnostic information from long-term memory rather than being a by-product of a retrieval opportunity. However, these data also suggest that theories proposing that the delayed JOL effect results from a memorial benefit or the match between the cues available for JOLs and those available at test may also provide viable explanatory mechanisms necessary for a comprehensive account. 相似文献
