Grammatical-specific language impairment (G-SLI) in children, arguably, provides evidence for the existence of a specialised grammatical sub-system in the brain, necessary for normal language development. Some researchers challenge this, claiming that domain-general, low-level auditory deficits, particular to rapid processing, cause phonological deficits and thereby SLI. We investigate this possibility by testing the auditory discrimination abilities of G-SLI children for speech and non-speech sounds, at varying presentation rates, and controlling for the effects of age and language on performance. For non-speech formant transitions, 69% of the G-SLI children showed normal auditory processing, whereas for the same acoustic information in speech, only 31% did so. For rapidly presented tones, 46% of the G-SLI children performed normally. Auditory performance with speech and non-speech sounds differentiated the G-SLI children from their age-matched controls, whereas speed of processing did not. The G-SLI children evinced no relationship between their auditory and phonological/grammatical abilities. We found no consistent evidence that a deficit in processing rapid acoustic information causes or maintains G-SLI. The findings, from at least those G-SLI children who do not exhibit any auditory deficits, provide further evidence supporting the existence of a primary domain-specific deficit underlying G-SLI. 相似文献

Intraindividual variability (inconsistency) in reaction time (RT) latencies was investigated in a group of younger (M=25.46 years) and older (M=69.29 years) men. Both groups performed 300 trials in 2-, 4-, and 8-choice RT conditions where RTs for decision and motor components of the task were recorded separately. A dissociation was evident in that inconsistency was greater in older adults for decision RTs when task demands relating to the number of choices and fatigue arising from time-on-task were high. For younger persons, a weak trend toward greater inconsistency in motor RTs was evident. The results are consistent with accounts suggesting that inconsistency in neurobiological mechanisms increases with age, and that attentional lapses or fluctuations in executive control contribute to RT inconsistency. 相似文献

Five experiments were conducted in order to determine which of two hypotheses, initially proposed by Rock (1990), accounts for interactions between oriented elements in a visual scene. We also explored the suggestion that two hypothetical processes--namely, frame of reference and hierarchical organization--describe phenomena arising from distinct mechanisms (Spinelli, Antonucci, Daini, Martelli, & Zoccolotti, 1999). Double inducing stimulus versions of one-dimensional and two-dimensional tilt illusions, the rod-and-frame illusion, and combinations of these were used. Our data suggest that both hypotheses can predict orientation interactions in conditions in which only one mechanism--namely, the global visual mechanism of symmetry axes extraction (Wenderoth & Beh, 1977)--is activated. Which hypothesis is appropriate to predict the perceived orientation depends on some physical features of the objects. 相似文献

The authors used 6-year longitudinal data from the Victoria Longitudinal Study (VLS) to investigate individual differences in amount of episodic memory change. Latent change models revealed reliable individual differences in cognitive change. Changes in episodic memory were significantly correlated with changes in other cognitive variables, including speed and working memory. A structural equation model for the latent change scores showed that changes in speed and working memory predicted changes in episodic memory, as expected by processing resource theory. However, these effects were best modeled as being mediated by changes in induction and fact retrieval. Dissociations were detected between cross-sectional ability correlations and longitudinal changes. Shuffling the tasks used to define the Working Memory latent variable altered patterns of change correlations. 相似文献

Recent estimates suggest that more than 10% of Southern Africa is HIV+. This article is based on a research study of sixty four pastoral care projects focussing on the HIV/AIDS pandemic in Southern Africa. The projects, which fall under the auspices of the Southern African Catholic Bishops' Conference AIDS office, focus on both education for HIV prevention and the pastoral care of people living with HIV/AIDS (PLWHA). The article recounts the results achieved by these projects over the last two years, discussing their strengths and weaknesses, and proposes some recommendations for further action. The author discusses the pastoral and theological dimensions of these pastoral services indicating the importance of socio-cultural mediation in pastoral responses. 相似文献

In this paper, a hypothesis from a theory of charismatic relationships is examined that incorporates follower's level of self-monitoring and state of self-awareness. It is argued that changes in the state of self-awareness affect the characteristics of the short-term charismatic relationship between leader and follower, but only for high self-monitoring followers. Providing support for the hypothesis was a repeated-measures study. Participants ( N = 78) viewed video vignettes of charismatic leaders presenting different messages, in either a high or low self-awareness condition. When high in self-awareness, participants with a high self-monitoring orientation were more likely than when in a state of low self-awareness to internalize only those messages congruent with their values and beliefs. 相似文献

The present study explores the biasing effects of gangsta’ rap lyrics on subject perceptions of a murder trial defendant's personality. The lyrics were those actually authored by a defendant in a murder trial on which the present author was a psychological consultant for the defense. Results strongly indicate that the defendant was seen as more likely to have committed a murder than had he not been presented as authoring such lyrics. Surprisingly, results also show that the writing of such rap lyrics was more damning in terms of adjudged personality characteristics than was the fact of being charged with murder. 相似文献
