PHONOLOGICAL CODES ARE AUTOMATICALLY ACTIVATED DURING READING: 总被引:4,自引:0,他引:4

Abstract— Subjects read sentences containing target words that were homophones (words with a single pronunciation but different spellings) while their eye movements were recorded A prime word was presented briefly at the onset of fixation on the target region The prime for a given target (e g, beach) was either identical to the target (beach, a phonologically similar word (the homophone beech), a visually similar nonhomophone (bench), or a dissimilar word (noise) Phonological priming effects were assessed by comparing fixation times on the target when It was preceded by the homophone versus the visually similar word Results suggest that phonological codes are automatically activated during eye fixations in reading 相似文献

Although there is considerable evidence that grapheme and body units are involved in assembling phonology from print, there is little evidence supporting the involvement of syllabic representations. We provide evidence on this point from a phonological dyslexic patient (ML) who, as a result of brain damage, is relatively unable to read nonwords. ML was found to be able to perform tasks assumed to reflect processes involved in assembled phonology (i.e. segmentation, orthographic-phonologic conversion, and blending) when the units involved were syllables, but demonstrated considerable difficulty when they were onset, body, or phoneme units. Additionally, both ML and matched controls were much better able to find words in an anagrams task (Treiman & Chafetz, 1987) when they resulted from the combination of segments corresponding to syllables than when they did not. It is suggested that the relationship between print and sound is represented at multiple levels (including the syllable) (Shallice, Warrington, & McCarthy, 1983) and that ML's nonword reading impairment is the result of disruption of representations below the level of the syllable. 相似文献

It was previously shown that variation of the catechol-O-methyltransferase (COMT) gene modulates brain activity during the processing of stimuli with negative valence, but not for pleasant stimuli. Here, we tested whether the COMT genotype also modulates the electrophysiological correlates of emotional processing and explored whether the environmental factor of life stress influences this effect. Using the early posterior negativity (EPN) paradigm, event-related brain potentials were measured in 81 healthy individuals during the processing of pictures that evoked emotions of positive and negative valence. As was hypothesized, the COMT genotype affected the EPN amplitudes for unpleasant stimuli, but not for pleasant ones. Specifically, Met/Met carriers respond more sensitively to unpleasant stimuli, as compared with Val/Val carriers. We did not find evidence that life stress moderates the effect of the COMT genotype on emotional stimuli processing. 相似文献

This article reports on a participatory process to generating a research agenda to guide research on community participation in HIV vaccine research. Community members representing stakeholder parties involved in the HIV vaccine research enterprise were invited to participate in the process. Fourty-five participants participated in the process and we used interactive techniques to stimulate discussion and interaction between community members at different levels of the HIV vaccine research enterprise. Through the process we generated a locally grounded research agenda to guide research on community participation in HIV vaccine research that originates out of the experiences, challenges and concerns of community members. 相似文献

The expression of aggressiveness, which constitutes many facets of behavior, is influenced by a complex interaction of biologic, psychologic, and social variables. Even though individual differences in impulsivity and the behavioral consequences, such as aggression, addiction, and suicidality, are substantially heritable, they ultimately result from an interplay between genetic variations and environmental factors. While formation and integration of multiple neural networks is dependent on the actions of neurotransmitters, such as serotonin (5HT), converging lines of evidence indicate that genetically determined variability in serotonergic gene expression influences complex traits including that of inappropriately aggressive behavior. This contribution reviews studies of major gene effects in inbred and knockout strains of mice with increased aggression-related behavior and discusses the relevance of several serotonergic gene variations in humans which include high aggressiveness as part of the phenotype. Although special emphasis is given to the molecular psychobiology of 5HT in aggression-related behavior in rodents, nonhuman primates, and humans, relevant conceptual and methodological issues in the search for candidate genes for impulsivity and aggressiveness and for the development of mouse models of aggressive and antisocial behavior in humans are also considered. 相似文献

A major issue in reading is the extent to which phonological information is used in visual word perception. The present experiments demonstrated that phonological information acquired on 1 fixation from a word in the parafovea is used to help identify that word when it is later fixated. A homophone of a target word, when presented as a preview in the parafovea, facilitated processing of the target word seen on the next fixation more than a preview of a word matched with the homophone in visual similarity to the target word. This facilitation was observed both in the time to name an isolated target word and in the fixation time on the target word while silently reading a sentence; the preview was virtually never consciously identified in either task. Because the visual similarity of the preview to the target also plays a part in the facilitative effect on the preview, however, codes other than phonological codes are preserved across saccades. 相似文献

Three experiments investigated cross-form transfer in the invariance learning paradigm introduced by McGeorge and Burton (1990). The results suggest that the transfer observed by McGeorge and Burton depended on subjects' ability to use a response strategy discovered by Wright and Burton (1995). When that strategy was denied to subjects (Experiments 1 and 2), no cross-form transfer was observed; when the strategy was made available (Experiment 3), cross-form transfer re-emerged. These results suggest that this form of learning, like many other forms of implicit learning and memory, is hyperspecific. 相似文献

This study investigated the reliability of the Dyadic Satisfaction (DS) subscale of the Dyadic Adjustment Scale (DAS) in a South African setting. One-hundred heterosexual, coloured, low-income, semi-rural couples with a mean age of 43.59 years and limited formal education participated in the study. To estimate validity, the DS subscale was correlated with the Index of Marital Satisfaction (IMS) and the Kansas Marital Satisfaction Scale (KMSS). There appears to be a particularly strong relationship between the DS subscale and the IMS. The DS subscale can be used reliably as a measure of relationship satisfaction in the South African community studied. 相似文献
