Learning a second language as an adult is particularly effortful when new phonetic representations must be formed. Therefore the processes that allow learning of speech sounds are of great theoretical and practical interest. Here we examined whether perception of single formant transitions, that is, sound components critical in speech perception, can be enhanced through an implicit task-irrelevant learning procedure that has been shown to produce visual perceptual learning. The single-formant sounds were paired at subthreshold levels with the attended targets in an auditory identification task. Results showed that task-irrelevant learning occurred for the unattended stimuli. Surprisingly, the magnitude of this learning effect was similar to that following explicit training on auditory formant transition detection using discriminable stimuli in an adaptive procedure, whereas explicit training on the subthreshold stimuli produced no learning. These results suggest that in adults learning of speech parts can occur at least partially through implicit mechanisms. 相似文献

The present study examined whether results of athletes' eye movements while they observe fencing attacks reflect their actual information pickup by comparing these results with others gained with temporal and spatial occlusion and cuing techniques. Fifteen top-ranking expert fencers, 15 advanced fencers, and 32 sport students predicted the target region of 405 fencing attacks on a computer monitor. Results of eye movement recordings showed a stronger foveal fixation on the opponent's trunk and weapon in the two fencer groups. Top-ranking expert fencers fixated particularly on the upper trunk. This matched their performance decrements in the spatial occlusion condition. However, when the upper trunk was occluded, participants also shifted eye movements to neighboring body regions. Adding cues to the video material had no positive effects on prediction performance. We conclude that gaze behavior does not necessarily represent information pickup, but that studies applying the spatial occlusion paradigm should also register eye movements to avoid underestimating the information contributed by occluded regions. 相似文献

The ease with which information comes to mind can impact judgment. We examine whether the influence of ease of retrieval is moderated by situational factors that call it to attention before judgment and by individual differences in experiential processing style, as measured by the rational experiential inventory scale (Pacini & Epstein, 1999). An ease of retrieval effect, indicated by less favorable evaluations of a proposal following the retrieval of many reasons advocating the proposal than following the retrieval of only a few, was found for high‐experiential style processors regardless of situational factors that made ease of retrieval salient. However, the effect was found among low‐experiential style processors only when ease of retrieval was explicitly called to their attention prior to judgment. 相似文献

The use of virtual environments with head-mounted displays (HMDs) offers unique assets to the evaluation and therapy of clinical populations. However, research examining the effects of this technology on clinical populations is sparse. Understanding how wearers interact with the HMD is vital. Discomfort leads to altered use of the HMD that could confound performance measures; the very measures which might be used as tools for clinical decision making. The current study is a post-hoc analysis of the relationship between HMD use and HMD comfort. The analysis was conducted to examine contributing factors for a high incidence of simulator sickness observed in an HMD-based driving simulator. Pearson correlation analysis was used to evaluate objective and subjective measures of HMD performance and self-reported user comfort ratings. The results indicated weak correlations between these variables, indicating the complexity of quantifying user discomfort and HMD performance. Comparison of two case studies detailing user behavior in the virtual environment demonstrates that selected variables may not capture how individuals use the HMD. The validity and usefulness of the HMD-based virtual environments must be understood to fully reap the benefits of virtual reality (VR) in rehabilitation medicine. 相似文献

The article investigates the sociocultural implications of the changing modern workplace and of pharmacological cognitive enhancement (PCE) as a potential adaptive tool from the viewpoint of social niche construction. We will attempt to elucidate some of the sociocultural and technological trends that drive and influence the characteristics of this specific niche, and especially to identify the kind of capabilities and adaptations that are being promoted, and to ascertain the capabilities and potentialities that might become diminished as a result. In this context, we will examine what PCE is, and how and why it might be desirable as a tool for adaptation within the workplace. As human beings are, or at least should be allowed to be, more than merely productive, able-bodied and able-minded workers, we will further examine how adaptation to the workplace niche could result in problems in other domains of modern societal life that require the same or other cognitive capabilities. In this context we will also focus on the concept of responsibility and how it pertains to PCE and the modern workplace niche. This will shed some light on the kind of trends related to workplace niche construction, PCE and capability promotion that we can expect in the future, and on the contexts in which this might be either beneficial or detrimental to the individual as a well-rounded human being, and to other members of society. 相似文献

An attachment theoretical model of individual differences in God concepts among kindergarteners was tested. Subjects were 72 kindergarteners (mean age 63 months) from two elementary schools. Children's concepts of self, other, and God were measured using structured questionnaires. A questionnaire and an incomplete doll story procedure were used to tap the quality of the teacher-child and mother-child relationship. The model was partly supported. Contrary to our expectations, a punishing concept of God was not related to any of the independent variables. However, in line with the model, harmony and closeness in the teacher-child relationship predicted a loving God concept and this association was explained by children's working models of self. Working models of others predicted a loving God concept. Although the child's representation of the mother-child attachment relationship was significantly connected to the teacher-child relationship, it was not predictive of the concept of God. 相似文献

Sound categorisation plays a crucial role for processing ecological and social stimuli in a species’ natural environment.
To explore the discrimination and evaluation of sound stimuli in human babies and nonhuman primates, a reciprocal habituation-dishabituation
paradigm has been successfully introduced into auditory research. We applied the reciprocal paradigm for the first time to
a non-primate mammal, the tree shrew (Tupaia belangeri), to examine to what extent non-primate mammals share the ability to evaluate communication calls with primates. Playback
stimuli were three types of communication calls, differing distinctively in context and acoustic structure, as well as two
artificial control sounds, differing solely in frequency. We assessed the attention towards the playback stimuli by the latency
to respond to the test stimulus. Subjects evaluated pairs of communication call types as well as the artificial playback stimuli.
Attention towards the test stimuli differed significantly in strength for one pair of communication calls, with subjects dishabituating
faster to one category than the other. The comparison of a second pair of communication calls did not show significant differences.
Interestingly, subjects also evaluated the artificial control sounds. Findings are only partly in line with results on human
and non-human primates. They provided first evidence that in non-primate mammals acoustic evaluation is not solely affected
by the sound-associated context but is also linked to unusualness and acoustic cues, such as peak frequency. 相似文献
