为探索精神分裂症患者自我面孔识别的能力以及在视听整合任务中面孔对声音身份识别(同性和异性)的影响, 选取34名住院精神分裂症患者和26名健康被试, 分别进行单通道动态自我面孔识别任务、单通道自我声音识别任务和视听整合任务的3个实验。结果发现:精神分裂症患者的单通道自我面孔识别能力和自我声音识别能力与健康组无区别, 但在视听整合任务中, 精神分裂症患者的声音身份识别受到视觉通道面孔识别的影响。结果表明, 精神分裂症患者有自我面孔识别的能力, 自我面孔会促进自我声音的识别, 并抑制对同性他人声音和异性他人声音的识别。 相似文献

The aim of the present study was to determine whether the self-enhancement effect of voice attractiveness evaluation is due to general self-positivity bias and/or the familiarity effect. The participants were asked to rate the attractiveness of their own voice, a friend's voice and strangers' voices. In addition, a self-reference valence (SR-valence) task was adopted in the experiment. Significant self-enhancement effects in voice attractiveness ratings were demonstrated, regardless of whether the participants recognized their self-voice or not. However, the friend-enhancement effect was found in only those participants who successfully recognized their friend's voice. Moreover, a significant correlation was found between self-positivity bias in the SR-valence task and the self-enhancement effect (but not the friend-enhancement effect). Our findings suggest that both the familiarity effect and self-positivity bias account for the vocal self-enhancement effect, and the influence of self-positivity bias could be implicit. The present study thus provides empirical evidence to clarify the potential explanations for the self-enhancement of voice attractiveness assessment. 相似文献

Information associated with the self is prioritized relative to information associated with others and is therefore processed more quickly and accurately. Across three experiments, we examined whether a new externally-generated voice could become associated with the self and thus be prioritized in perception. In the first experiment, participants learned associations between three unfamiliar voices and three identities (self, friend, stranger). Participants then made speeded judgements of whether voice-identity pairs were correctly matched, or not. A clear self-prioritization effect was found, with participants showing quicker and more accurate responses to the newly self-associated voice relative to either the friend- or stranger- voice. In two further experiments, we tested whether this prioritization effect increased if the self-voice was gender-matched to the identity of the participant (Experiment 2) or if the self-voice was chosen by the participant (Experiment 3). Gender-matching did not significantly influence prioritization; the self-voice was similarly prioritized when it matched the gender identity of the listener as when it did not. However, we observed that choosing the self-voice did interact with prioritization (Experiment 3); the self-voice became more prominent, via lesser prioritization of the other identities, when the self-voice was chosen relative to when it was not. Our findings have implications for the design and selection of individuated synthetic voices used for assistive communication devices, suggesting that agency in choosing a new vocal identity may modulate the distinctiveness of that voice relative to others. 相似文献
