Measuring the speed of recognising facially expressed emotions 总被引:1,自引:0,他引:1
Faces provide identity- and emotion-related information-basic cues for mastering social interactions. Traditional models of face recognition suggest that following a very first initial stage the processing streams for facial identity and expression depart. In the present study we extended our previous multivariate investigations of face identity processing abilities to the speed of recognising facially expressed emotions. Analyses are based on a sample of N=151 young adults. First, we established a measurement model with a higher order factor for the speed of recognising facially expressed emotions (SRE). This model has acceptable fit without specifying emotion-specific relations between indicators. Next, we assessed whether SRE can be reliably distinguished from the speed of recognising facial identity (SRI) and found latent factors for SRE and SRI to be perfectly correlated. In contrast, SRE and SRI were both only moderately related to a latent factor for the speed of recognising non-face stimuli (SRNF). We conclude that the processing of facial stimuli-and not the processing of facially expressed basic emotions-is the critical component of SRE. These findings are at variance with suggestions of separate routes for processing facial identity and emotional facial expressions and suggest much more communality between these streams as far as the aspect of processing speed is concerned. 相似文献

Implicit word learning benefits from semantic richness: electrophysiological and behavioral evidence
Rabovsky M Sommer W Abdel Rahman R 《Journal of experimental psychology. Learning, memory, and cognition》2012,38(4):1076-1083
Words differ considerably in the amount of associated semantic information. Despite the crucial role of meaning in language, it is still unclear whether and how this variability modulates language learning. Here, we provide initial evidence demonstrating that implicit learning in repetition priming is influenced by the amount of semantic features associated with a given word. Electroencephalographic recordings were obtained while participants performed a visual lexical decision task; the complete stimulus set was repeated once. Repetition priming effects on performance accuracy and the N400 component of the event-related brain potential were enhanced for words with many semantic features. These findings suggest a novel and important impact of the richness of semantic representations on learning and plasticity within the lexical-conceptual system; they are discussed in their relevance for assumptions concerning basic mechanisms underlying word learning. 相似文献

A central tenet of current memory theories is the independence of data-driven and conceptually driven priming. Although these types of repetition priming have different functional properties, it has remained unclear whether they are independent and additive or interact with each other. Therefore, we orthogonally combined these priming types in two experiments requiring occupation judgments for celebrities, represented by their faces or names. In both experiments, the sum of the effects of separate data-driven priming and conceptually driven priming equaled the effect of the combination of these priming types. These findings demonstrate for the first time the independence of data-driven and conceptually driven priming and so confirm a central tenet of current memory theories. This independence may thus be an important element for the development of future overarching memory theories. 相似文献

ABSTRACT. Research suggests that children may interfere with single parents’ romantic experiences. Although both male and female single parents face these challenges, they have stronger associations with the romantic satisfaction of single mothers as compared to single fathers. The two current studies examined aspects of attractiveness and dating across various dimensions for both younger single women and men, with and without children. Results of Study 1 indicated interactive effects of target gender and parental status on perceptions of both attractiveness and dating potential. Results of Study 2 indicated differential ratings on multiple dimensions (i.e., attractiveness, stress, motivation for dating, and positive qualities) of younger single adults on the basis of gender, parental status, and the number of children single parents were reported as having. Implications for importance of social support and difficulty of repartnering are discussed. 相似文献

The degree to which emotional aspects of stimuli are processed automatically is controversial. Here, we assessed the automatic elicitation of emotion-related brain potentials (ERPs) to positive, negative, and neutral words and facial expressions in an easy and superficial face-word discrimination task, for which the emotional valence was irrelevant. Both emotional words and facial expressions impacted ERPs already between 50 and 100 ms after stimulus onset, possibly reflecting rapid relevance detection. Following this initial processing stage only emotionality in faces but not in words was associated with an early posterior negativity (EPN). Therefore, when emotion is irrelevant in a task which requires superficial stimulus analysis, automatically enhanced sensory encoding of emotional content appears to occur only for evolutionary prepared emotional stimuli, as reflected in larger EPN amplitudes to faces, but not to symbolic word stimuli. 相似文献

Face cognition is considered a specific human ability, clearly differentiable from general cognitive functioning. Its specificity is primarily supported by cognitive-experimental and neuroimaging research, but recently also from an individual differences perspective. However, no comprehensive behavioral data are available, which would allow estimating lifespan changes of the covariance structure of face-cognition abilities and general cognitive functioning as well as age-differences in face cognition after accounting for interindividual variability in general cognition. The present study aimed to fill this gap. In an age-heterogeneous (18-82 years) sample of 448 adults, we found no factorial dedifferentiation between face cognition and general cognition. Age-related differences in face memory were still salient after taking into account changes in general cognitive functioning. Face cognition thus remains a specific human ability compared with general cognition, even until old age. We discuss implications for models of cognitive aging and suggest that it is necessary to include more explicitly special social abilities in those models. 相似文献

Impaired emotional responsiveness has been revealed as a hallmark of psychopathy. In spite of an increasing database on emotion processing, studies on cognitive function and in particular on the impact of emotion on cognition in psychopathy are rare. We used pictures from the International Affective Picture Set (IAPS) and a Simon Paradigm to address emotion-cognition interaction while functional and structural imaging data were obtained in 12 healthy controls and 10 psychopaths. We found an impaired emotion-cognition interaction in psychopaths that correlated with a changed prefrontal and temporal brain activation. With regard to the temporal cortex, it is shown that structure and function of the right superior temporal gyrus is disturbed in psychopathy, supporting a neurobiological approach to psychopathy, in which structure and function of the right STG may be important. 相似文献

Despite the importance of face recognition in everyday life and frequent complaints about its failure, there is no comprehensive test battery for this ability. As a first step in constructing such a battery, we present 18 tasks aimed at measuring face perception, face learning, face recognition, and the recognition of facially expressed emotions. A sample of 153 healthy young adults completed all tasks. In general, reaction time measures showed high estimates of internal consistency; tasks focused on performance accuracy yielded reliabilities that were somewhat lower, yet high enough to support their use in a battery of face cognition measures. Some of the tasks allowed computation of established experimental effects in a within-subjects design, such as the part-whole effect. Most of these experimental effects were confirmed in our large sample, and valuable effect size estimates were obtained. However, in many cases these difference measures showed poor estimates of internal consistency. 相似文献

On the basis of current emotion theories and functional and neurophysiological ties between the processing of conflicts and
errors on the one hand and errors and emotions on the other hand we predicted that conflicts between prepotent Go responses
and occasional NoGo trials in the Go/NoGo task would induce emotions. Skin conductance responses (SCRs), corrugator muscle
activity, and startle blink responses were measured in three experiments requiring speeded Go responses intermixed with NoGo
trials of different relative probability and in a choice reaction experiment serving as a control. NoGo trials affected several
of these emotion-sensitive indicators as SCRs and startle blinks were reduced whereas corrugator activity was prolonged as
compared to Go trials. From the pattern of findings we suggest that NoGo conflicts are not aversive. Instead, they appear
to be appraised as obstructive for the response goal and as less action relevant than Go trials. 相似文献
