In this study, we examined whether integration of visual and auditory information about emotions requires limited attentional resources. Subjects judged whether a voice expressed happiness or fear, while trying to ignore a concurrently presented static facial expression. As an additional task, the subjects had to add two numbers together rapidly (Experiment 1), count the occurrences of a target digit in a rapid serial visual presentation (Experiment 2), or judge the pitch of a tone as high or low (Experiment 3). The visible face had an impact on judgments of the emotion of the heard voice in all the experiments. This cross-modal effect was independent of whether or not the subjects performed a demanding additional task. This suggests that integration of visual and auditory information about emotions may be a mandatory process, unconstrained by attentional resources.  相似文献

Root nonfinite structures are frequent in both child language and agrammatic speech. Moreover, root nonfinites seem to have quite similar properties in both types of speech. Although many accounts are available for child language this is not the case for agrammatic speech. I present data of a Dutch agrammatic patient in this paper. The properties of her root nonfinites are best accounted for by the assumption of an underspecified Tense Phrase licensed by an empty element. In her finite sentences a dummy Tense element shows up. The use of either an empty or a dummy Tense element is a way of reducing the processing load of the utterance. The speech of this patient shows a dissociation between the verbal and the nominal domain.  相似文献

This study examined the relation between a subjective and a behavioral measure of the vividness of auditory imagery as well as the disposition towards hallucination in normal subjects. In addition to the Launay-Slade Hallucination Scale, subjects (57 university students) completed the Betts questionnaire in which they rated the vividness of their experienced mental images and performed a behavioral task aimed at measuring auditory imagery. The task consisted of a perception and an imagery condition in which subjects had to indicate the odd one of three everyday sounds. Performance on the behavioral task did not correlate with the auditory or scores on the Visual subscale of the Betts. In addition, neither scores on the behavioral measure nor the Auditory subscale of the Betts correlated significantly with hallucinatory predisposition as rated on the Launay-Slade Hallucination Scale. In contrast, the Visual subscale of the Betts did correlate with scores on the Launay-Slade Hallucination Scale, consistent with previous research. We conclude that there is no straightforward relationship between imagery vividness and hallucinatory experiences and that subjective and objective indices of imagery vividness measure different aspects of mental function.  相似文献

This study tested the influence of personal characteristics on a pattern of specific relationships between work characteristics and psychological outcomes. The study hypotheses were: (1) Growth Need Strength has a direct effect on intrinsic work motivation and moderates the relationship between task characteristics and intrinsic work motivation; (2) Negative Affectivity has a direct effect on emotional exhaustion and moderates the relationships between workload and social support on the one hand and emotional exhaustion on the other; and (3) Upward Striving has a direct effect on turnover intention and moderates the relationship between unmet career expectations and turnover intention. These hypotheses were tested in two samples (bank employees and teachers) using Multi-Sample Analysis. The results showed that, generally, personal characteristics had a direct effect on the outcomes as hypothesized. We only found one moderating effect: Upward Striving moderated the relationship between unmet career expectations and turnover intention.  相似文献

Moral Emotions     
Emotions can be the subject of moral judgments; they can also constitute the basis for moral judgments. The apparent circularity which arises if we accept both of these claims is the central topic of this paper: how can emotions be both judge and party in the moral court? The answer I offer regards all emotions as potentially relevant to ethics, rather than singling out a privileged set of moral emotions. It relies on taking a moderate position both on the question of the naturalness of emotions and on that of their objectivity as revealers of value: emotions are neither simply natural nor socially constructed, and they apprehend objective values, but those values are multi‐dimensional and relative to human realities. The “axiological” position I defend jettisons the usual foundations for ethical judgments, and grounds these judgments instead on a rationally informed reflective equilibrium of comprehensive emotional attitudes, tempered with a dose of irony.  相似文献

In this paper we study in details a system of two weakly coupled harmonic oscillators from the point of view of Bohm’s interpretation of quantum mechanics. This system may be viewed as a simple model for the interaction between a photon and a photodetector. We obtain exact solutions for the general case. We then compute approximate solutions for the case where one oscillator is initially in its first excited state (a single photon) reaching the other oscillator in its ground state (the photodetector). The approximate solutions represent the state of both oscillators after the interaction, which is not an eigenstate of the individual hamiltonians for each oscillator, and therefore the energies for each oscillator do not exist in the Copenhagen interpretation of Quantum Mechanics. We use the approximate solutions that we obtained to compute Bohmian trajectories and to study the energy transfer between the oscillators. We conclude that, even using the Bohmian view, the energy of each individual oscillator is not well defined, as the nonlocal quantum potential is not negligible even after the coupling is turned off.  相似文献
