Are speech-specific processes localized in dedicated cortical regions or do they emerge from developmental plasticity in the connections among non-dedicated regions? Here we claim that all the brain regions activated by the processing of auditory speech can be re-classified according to whether they respond to non-verbal environmental sounds, pitch changes, unfamiliar melodies, or conceptual processes. We therefore argue that speech-specific processing emerges from differential demands on auditory and conceptual processes that are shared by speech and non-speech stimuli. This has implications for domain- vs. process-specific cognitive models, and for the relative importance of segregation and integration in functional anatomy. 相似文献

Love, Rouder, and Wisniewski (1999) and Ripoll and Marty (2005) showed that subjects could process global properties very quickly in a same/different task on abstract visual scenes for which the conspicuity of local and global properties had been controlled. In this new experiment, two important new factors were manipulated: saliency of the global pattern and location of local similarity. The results showed that the saliency of the global form as well as the location of local similarity determines the strength of global and local effects. Global effects continue to manifest themselves even when the extraction of the global form is difficult. Finally, the whole pattern of results suggests that local and global processing proceeds simultaneously and involves two attentional systems whose spatial characteristics are very different. 相似文献

Depressed participants display longer reaction times (RTs) than control participants. The present study was aimed at deciphering which stages of processing are affected by depression in old adults. Sixteen old depressed patients and 16 old healthy volunteers performed a two-choice visual RT task. Signal intensity, stimulus-response mapping and foreperiod duration were manipulated so as to affect the stages of stimulus preprocessing, response selection and motor adjustment, respectively. Reaction time data suggest that depression spares the stage of stimulus preprocessing but affects the stage of motor adjustment. An analysis of the error rate leaves open the possibility that depression alters the stage of response selection. 相似文献

The Swiss sublines of Roman high-(RHA/Verh) and low-(RLA/Verh) avoidance rats have been genetically selected for good vs. poor performance in two-way active avoidance since 1972. RLA/Verh rats show increased stress responses (e.g. freezing behaviour, ACTH, corticosterone and prolactin secretion) and adopt a more passive (or reactive) coping style when confronted with a novel environment. In the open field, elevated plus-maze, black/white box test, and in a new light/dark open field test, RLA/Verh rats appear to be more anxious than their RHA/Verh counterparts. Anxiety may result from their particular psychophysiological profile, i.e. increased emotionality combined with a passive coping style. In contrast, RHA/Verh rats are less responsive to stress, they show little anxiety in novel situations and tend to be impulsive and novelty (sensation) seekers. Some behavioural differences are already noticeable shortly after birth, but the full pattern appears to stabilize only after puberty. Gene-environment interactions are critical in establishing this pattern. The data reviewed indicate that the differences between RHA/Verh and RLA/Verh rats probably result from a complex interaction among divergent anxiety/emotionality characteristics, differences in locomotor activity and novelty/reward seeking, as well as active vs. passive coping styles. It is proposed further that these divergent personality types are to be found not only in other selective breeding programs but in the form of individual differences in most populations of rats used for this type of research. 相似文献

According to dominant models of reasoning by analogy, analogical transfer requires subjects to first define a full one-to-one correspondence between the base and the target problems. Accordingly, these models predict that if there is a cross-mapping between the base and the target (cross-mapping exists when similar or identical elements in the base and the target play different roles), the time spent transferring a property from the base to the target will be greater. The present results are inconsistent with this prediction. Indeed, if the mapping task is more difficult in the cross-mapping condition than in the control condition, the time needed to make the transfer is not affected by the presence of a cross-mapping. Consequently, we conclude that the mapping phase is not a necessary condition for transfer. 相似文献

Pointing tasks with a mouse are very useful in psychological experiments concerned with a subject’s ability to track a visual object or to move to a target location (e.g., to find a word in text). Such tasks are quite easily performed by subjects, and numerous variables may be obtained from the mouse movement. In this article we describe a set of Turbo Pascal 6.0 units and a program running on the IBM PC family that show how data (x,y coordinates) recorded from a mouse movement can be analyzed to give dispersion, direction, and distance of the movement. 相似文献

Considered from a logical point of view, Confucius’ Analects contain many implicit forms of reasoning and argumentation. This is shown first by analyzing the phenomenon of parallelism: direct parallelism is often a way of hinting at a general assertion, whereas anti-parallelism hides dilemmas, generalizations and modal notions of “moral preference.” The Analects also have various types of conditionals, ranging from material implications, to modalized implications, and counterfactual conditionals, which are the germs of implicit reasoning, concluding with a moral recommendation. Analogies are particularly abundant and a presentation of three examples suggests that, beyond their explicative role, they also involve moral recommendations. The implicit logic of The Analects requires an active, albeit unconscious participation of the reader, which could be an important element in explaining the enduring influence of the text. 相似文献

Approach/avoidance paradigms could constitute an interesting alternative in measuring intergroup attitudes, notably if they overcome one criticism often addressed toward classic indirect tasks: Measuring attitudes beyond the influence of cultural knowledge. Using intergroup stimuli and a population likely to be exposed to a similar cultural knowledge, we observed two informative results regarding this issue: Approach/avoidance effects measured by the Visual Approach/Avoidance by the Self Task (VAAST) varied across participants (i.e., consistent with the variability of intergroup attitudes; Experiment 1) and both participants of dominant and non-dominant groups produced an ingroup bias (Experiment 2). A last experiment (Experiment 3) showed that compatibility scores in the VAAST predict trustworthiness ratings of the ingroup/outgroup. This experiment also investigated potential differences between the VAAST and the IAT. These results suggest that approach/avoidance tasks (notably the VAAST) could be relevant to assess personal attitudes when it comes to normatively sensitive topics. 相似文献

In choice reaction time tasks, subjects speed up before making an error, but slow down afterward to prevent the occurrence
of a new error. In some trials, the correct response is preceded by an incorrect electromyographic (EMG) activation too small
to reach the response threshold. In this article, we show that these incorrect EMG activations give rise to the same sequential
effects as overt errors: Before a trial containing an incorrect EMG activation, subjects speed up, whereas after that trial,
they slow down. These activations reflect errors that have been detected, inhibited, and corrected in time. As such, they
index the involvement of online executive control. 相似文献
