This paper examines the possibility that perception of vibrotactile speech stimuli is enhanced in adults with early and life-long use of hearing aids. We present evidence that vibrotactile aid benefit in adults is directly related to the age at which the hearing aid was fitted and the duration of its use. The stimulus mechanism responsible for this effect is hypothesized to be long-term vibrotactile stimulation by high powered hearing aids. We speculate on possible mechanisms for enhanced vibrotactile speech perception as the result of hearing aid use: (1) long-term experience receiving degraded or impoverished speech stimuli results in a speech processing system that is more effective for novel stimuli, independent of perceptual modality; and/or (2) long-term sensory/perceptual experience causes neural changes that result in more effective delivery of speech information via somatosensory pathways. 相似文献

The Effect of Genetic Counseling on Knowledge and Perceptions Regarding Risks for Breast Cancer 总被引:1,自引:0,他引:1

In 1994, a clinic for cancer risk counseling was opened at Hadassah University Hospital in Jerusalem. Most of the counselees have been women who had breast cancer and/or a relative with breast cancer. In order to evaluate the effect of this counseling on women's knowledge and perceptions regarding the risks for breast cancer, a questionnaire was given before and after the counseling session to 60 healthy women who came to the clinic because they have relatives with breast cancer. According to the genetic counselors' estimations, most of these women had a significantly increased risk (compared to the general population) of developing cancer. Before counseling, the women overestimated the population risk for breast cancer, the contribution of heredity to morbidity of cancer, and their own risks to get cancer. After counseling session, they gave reduced estimates, closer to the real ones. The subjective perceptions regarding these risks were reduced after counseling, except for the perceptions regarding their relativerisks which have not changed after the counseling. About 90% of the women who came to the clinic wanted to be tested for genetic predisposition to cancer. For most of these women, the expectations that the test can rule out a genetic predisposition to cancer became more realistic after the counseling. The option to first test an affected relative was offered to all families, and a test was actually conducted in 75% of the families. 相似文献

The role of spatial co-location between sight and sound in infants' cross-modal learning was examined in three experiments. Four-and 6-month-old infants were familiarized with a toy and an accompanying soundtrack. Across conditions, spatial congruity between sight and sound was varied. Following familiarization, infants were tested to determine under which conditions they learned to associate the toy with the sound. Results indicated age-related differences in how discrepant in location a sight and sound could be for infants to form a cross-modal association based on the amodal invariant of co-location. Specifically, 4-month-olds formed cross-modal associations under conditions of less precise co-location than did 6-month-olds. Parallel improvements in infants' sound localization abilities across this age span are likely a contributing factor to the observed developmental trend in cross-modal learning. 相似文献

Theories of autobiographical memory distinguish between involuntary and voluntary retrieval as a consequence of conscious intention (i.e., wanting to remember). Another distinction can be made between direct and generative retrieval, which reflects the effort involved (i.e., trying to remember). However, it is unclear how intention and effort interacts. For example, involuntary memories and directly retrieved memories have been used interchangeably in the literature to refer to the same phenomenon of effortless, non‐strategic retrieval. More recent theoretical advances suggest that they are separate types of retrieval, one unintentional (involuntary), another intentional and effortless (direct voluntary retrieval), and a third intentional and effortful (generative voluntary retrieval). Whether this also entails differing phenomenological characteristics, such as vividness, rehearsal, or emotional valence, has not been previously investigated. In the current study, participants reported memories in an experimental paradigm designed to elicit voluntary and involuntary memories and rated them on a number of characteristics. If intention affects the retrieval process, then we should expect differences between the characteristics of involuntary and directly retrieved memories. The results imply that retrieval intention seems to differentiate how a memory appears in a person's mind. Furthermore, we argue that these differences in part could result from differences in encoding and consolidation. 相似文献

Poorer recognition of other‐race faces than own‐races faces has been attributed to a problem of discrimination (i.e., telling faces apart). The conclusion that ‘they all look the same to me' is based on studies measuring the perception/memory of highly controlled stimuli, typically involving only one or two images of each identity. We hypothesized that such studies underestimate the challenge involved in recognizing other‐race faces because in the real world, an individual's appearance varies in a number of ways (e.g., lighting, expression, hairstyle), reducing the utility of relying on pictorial cues to identity. In two experiments, Caucasian and East Asian participants completed a perceptual sorting task in which they were asked to sort 40 photographs of two unfamiliar identities into piles such that each pile contained all photographs of a single identity. Participants perceived more identities when sorting other‐race faces than own‐race faces, both when sorting celebrity (Experiment 1) and non‐celebrity (Experiment 2) faces, suggesting that in the real world, ‘they all look different to me'. We discuss these results in the light of models in which each identity is represented as a region in a multidimensional face space; we argue that this region is smaller for other‐race than own‐race faces. 相似文献

Extensive research has investigated societal and behavioral consequences of social group affiliation and identification but has been relatively silent on the role of perception in intergroup relations. We propose the perceptual model of intergroup relations to conceptualize how intergroup relations are grounded in perception. We review the growing literature on how intergroup dynamics shape perception across different sensory modalities and argue that these perceptual processes mediate intergroup relations. The model provides a starting point for social psychologists to study perception as a function of social group dynamics and for perception researchers to consider social influences. We highlight several gaps in the literature and outline areas for future research. Uncovering the role of perception in intergroup relations offers novel insights into the construction of shared reality and may help devise new and unique interventions targeted at the perceptual level. 相似文献

Recent research has revealed that a simple action (pressing a computer key) produced in response to a visual object prioritizes features of that object in subsequent visual search. The effects of simple action, however, have only been studied with search displays that required serial search. Here we explored whether simple actions have an effect when the target in visual search is always a salient singleton. Participants viewed a coloured shape at the beginning of each trial, and sometimes they acted (pressed the space bar) in response to it. In the subsequent search task, after acting (but not after viewing), the previously-seen colour affected search performance even though the target was always a salient singleton and the colour was uninformative. The results reveal that prior action can interact with bottom-up salience during search. Implications for our understanding of both visual search and repetition priming are discussed. 相似文献

It is often assumed that conceptual information impacts visual experience only after perceptual information has been extracted. However, the present study suggests that conceptual processing can interfere with perceptual processes, as reflected in target perception impairments that are specific to the location of conceptually salient distractors. Experiment 1 replicated previous findings that emotional distractors in a rapid serial visual presentation cause a spontaneous, spatially localized impairment in target perception, further finding that distractors that are merely featurally salient do not. Experiment 2 suggested that conceptually salient distractors that are non-emotional also elicit such spatially localized impairments, which are shorter lived than those following emotional distractors. Experiment 3 suggested that featurally salient distractors that are not conceptually salient engage a different, spatial attention mechanism. Together, these findings suggest that, whereas featurally salient distractors can capture spatial attention, conceptual distractors additionally engage mechanisms that suppress spatiotemporally competing targets. 相似文献

When driven at low speeds, cars operating in electric mode have been found to be quieter than conventional cars. As a result, the auditory cues which pedestrians and cyclists use to assess the presence, proximity and location oncoming traffic may be reduced, posing a safety hazard. This laboratory study examined auditory localisation of conventional and electric cars including vehicle motion paths relevant for cycling activity. Participants (N = 65) in three age groups (16–18, 30–40 and 65–70 year old) indicated the location and movement direction (approaching versus receding) of cars driven at 15, 30 and 50 km/h in two ambient sound conditions (low and moderate). Results show that low speeds, higher ambient sound level and older age were associated with worse performance on the location and motion direction tasks. In addition, participants were less accurate at determining the location of electric and conventional car sounds emanating from directly behind the participant. Implications for cycling safety and proposals for adding extra artificial noise or warning sounds to quiet (electric) cars are discussed. 相似文献
