In this paper, we study nonverbal listener responses on a corpus with multiple parallel recorded listeners. These listeners were meant to believe that they were the sole listener, while in fact there were three persons listening to the same speaker. The speaker could only see one of the listeners. We analyze the impact of the particular setup of the corpus on the behavior and perception of the two types of listeners: the listeners that could be seen by the speaker and the listeners that could not be seen. Furthermore, we compare the nonverbal listening behaviors of these three listeners to each other with regard to timing and form. We correlate these behaviors with behaviors of the speaker, like pauses and whether the speaker is looking at the listeners or not. 相似文献

Findings from three experiments support the conclusion that auditory primes facilitate the processing of related targets. In Experiments 1 and 2, we employed a crossmodal Stroop color identification task with auditory color words (as primes) and visual color patches (as targets). Responses were faster for congruent priming, in comparison to neutral or incongruent priming. This effect also emerged for different levels of time compression of the auditory primes (to 30 % and 10 % of the original length; i.e., 120 and 40 ms) and turned out to be even more pronounced under high-perceptual-load conditions (Exps. 1 and 2). In Experiment 3, target-present or -absent decisions for brief target displays had to be made, thereby ruling out response-priming processes as a cause of the congruency effects. Nevertheless, target detection (d') was increased by congruent primes (30 % compression) in comparison to incongruent or neutral primes. Our results suggest semantic object-based auditory–visual interactions, which rapidly increase the denoted target object’s salience. This would apply, in particular, to complex visual scenes. 相似文献

Abstract Psychological explanations of both spontaneous and experimentally induced panic anxiety stress the role of fear of fear, especially fear of bodily symptoms of arousal. Fear of fear is conceptually different from trait anxiety but may be associated with repeated experience of arousal symptoms in fearful situations, while frequent physical exercise may lead to habituation to these symptoms. To test this hypothesis, 44 healthy male volunteers, classified as having high or low trait anxiety and high or low aerobic fitness, underwent a single-dose adrenalin infusion (80 nanogram/kilogram bodyweight/minute). In both groups, during the experiment a significant rise in state anxiety was found; compared to the group with low trait anxiety, subjects with high trait anxiety reported higher levels of state anxiety, which could be attributed to differences in aerobic fitness. In the high-anxious group, subjects showed a greater decrease in state anxiety during the recovery phase. State anxiety during adrenalin was strongly associated with fear of bodily symptoms only in the high-anxious group. Correlations between trait anxiety and somatic anxiety were not significant; state anxiety scores tended to correlate negatively with physical fitness. It is concluded that these results lend support to a fear of fear-model of panic anxiety. 相似文献

Two criteria for an alternate form of the Blacky Test, designed to facilitate female identification with Blacky are suggested: 1) the main character must be perceived by females as more feminine than the original stimulus, and 2) the main character must not be viewed differently by male and female Ss in other respects. Semantic Differential ratings of both the original Blacky stimuli and a revised “sexually neutral” cat form (N = 320) indicated that an alternate version could meet both these requirements. Differences between the responses of female Ss to both forms were further shown to be a) generally specific to female Ss, b) specific to the character of Blacky (rather than Mama) and c) often enhanced when Ss made judgments after having seen all twelve cartoons of the test, rather than only the first two. 相似文献

The Autobiographical Memory Test (AMT) is used to assess the degree of specificity of autobiographical memory. The AMT usually contains cue words of both positive and negative valence, but it is unclear whether these valences form separate factors or not. Accordingly, confirmatory factor analysis assessed whether the AMT measures one overall factor, or whether different cue types are related to different factors. Results were consistent across three datasets (N = 333, N = 405, and N = 336). A one-factor model fitted each dataset well, which suggests that responses to positive and negative cues are related to the one construct. In addition, item response theory analyses showed that the AMT is most precise for people who score low on memory specificity. Implications for using the AMT with high-functioning samples are discussed. 相似文献

Relativism about knowledge attributions is the view that a single occurrence of ‘S knows [does not know] that p’ may be true as assessed in one context and false as assessed in another context. It has been argued that relativism is equipped to accommodate all the data from speakers’ use of ‘know’ without recourse to an error theory. This is supposed to be relativism’s main advantage over contextualist and invariantist views. This paper argues that relativism does require the attribution of semantic blindness to speakers, viz. to account for sceptical paradoxes and epistemic closure puzzles. To that end, the notion of semantic blindness is clarified by distinguishing between content-blindness and index-blindness, and it is argued that the attribution of index-blindness required by the relativist account is implausible. Along the way, it is shown that error-theoretic objections from speakers’ inter-contextual judgments fail against relativism. 相似文献

ABSTRACTDot-probe studies usually find an attentional bias towards threatening stimuli only in anxious participants, but not in non-anxious participants. In the present study, we conducted two experiments to investigate whether attentional bias towards angry faces in unselected samples is moderated by the extent to which the current task requires social processing. In Experiment 1, participants performed a dot-probe task involving classification of either socially meaningful targets (schematic faces) or meaningless targets (scrambled schematic faces). Targets were preceded by two photographic face cues, one angry and one neutral. Angry face cues only produced significant cueing scores (i.e. faster target responses if the target replaced the angry face compared to the neutral face) with socially meaningful targets, not with meaningless targets. In Experiment 2, participants classified only meaningful targets, which were either socially meaningful (schematic faces) or not (schematic houses). Again, mean cueing scores were significantly moderated by the social character of the targets. However, cueing scores in this experiment were non-significant in the social target condition and significantly negative in the non-social target condition. These results suggest that attentional bias towards angry faces in the dot-probe task is moderated by the activation of a social processing mode in unselected samples. 相似文献

Although laughter plays an essential part in emotional vocal communication, little is known about the acoustical correlates that encode different emotional dimensions. In this study we examined the acoustical structure of laughter sounds differing along four emotional dimensions: arousal, dominance, sender's valence, and receiver-directed valence. Correlation of 43 acoustic parameters with individual emotional dimensions revealed that each emotional dimension was associated with a number of vocal cues. Common patterns of cues were found with emotional expression in speech, supporting the hypothesis of a common underlying mechanism for the vocal expression of emotions. 相似文献

It has been repeatedly stated that approach and avoidance reactions to emotional faces are triggered by the intention signalled by the emotion. This line of thought suggests that each emotion signals a specific intention triggering a specific behavioural reaction. However, empirical results examining this assumption are inconsistent, suggesting that it might be too short-sighted. We hypothesise that the same emotional expression can signal different social messages and, therefore, trigger different reactions; which social message is signalled by an emotional expression should be influenced by moderating variables, such as the group membership of the expresser. In two experiments, we show that group membership influences approach and avoidance reactions to emotional expressions: Emotions (fear and happiness) expressed by in-group members elicited concordant behaviour, whereas emotions expressed by out-group members activated the reverse pattern. A third experiment, in which participants directly evaluated smiling and fearful individuals resembling in-group and out-group members supported this result. 相似文献
