The evidence of supporting phonological deficit as a cause of developmental dyslexia has been accumulating rapidly over the past 2 decades, yet the exact mechanisms underlying this deficit remain controversial. Some authors assume that a temporal processing deficit is the source of the phonological disorder observed in dyslexic children. Others maintain that the phonological deficit in dyslexia is basically linguistic, not acoustic, in nature. Three experiments were conducted and tested the impact of the temporal alteration and the impact of complex syllabic structure on consonant order judgments. Thirteen phonological dyslexics (age 10-13) and 10 controls matched for chronologial age were compared on a Temporal Order Judgment (TOJ) task using the succession of two consonants (/p/ /s/) within a cluster. In order to test the possible relevance of the temporal deficit hypothesis, the task also included two additional conditions where either the two stimuli were artificially slowed or two phonological structures were opposed (CCV and CVCV). As expected, the TOJ performance was significantly poorer in dyslexics than in controls. Moreover, in the "slowed speech" condition dyslexics' performance improved to reach the normal controls' level, whereas manipulating the phonological structure complexity provided no significant improvement. Finally dyslexics' performances, especially on the slowed condition, were found correlated with several tests of phonological processing. These results lend support to the general temporal deficit theory of dyslexia. 相似文献

Information obtained at interview from 1,646 parasuicide patients in 14 regions in 13 European countries participating in the WHO/EURO Multicentre Study on Suicidal Behaviour was used to study self-reported intentions involved in parasuicide. Comparisons were made across cultures, genders, and age groups. Although some statistically significant differences were found, the effect sizes were very small. The main finding from this study is thus that parasuicide patients in different countries tend to indicate that similar types of intentions are involved in their acts of parasuicide, and that the intentions do not vary greatly with gender or age. The hypothesis that rates of suicide and parasuicide vary between regions with the frequency with which suicidal intention is indicated by the patients was also tested, but was supported only for women and in relation to national suicide rates. The findings from this study are likely to be generalizable to other settings and have implications for clinical practice. 相似文献

The goal of this study was to identify the predictors and the moderators of group characteristics that influence deviancy and normative training processes in delinquent male adolescents. The authors experimentally tested the effects of group composition on deviant talk interaction processes among groups in which all members presented delinquent behaviors (“pure” delinquent group condition), those that included adolescents with no delinquent behaviors (“pure” normative group condition), and adolescents with both profiles (“mixed” group condition). Participants were 70 male adolescents aged 15–18 (M = 16.5; 56% Caucasian), with a random assignment to groups. Data were collected among three group sessions (T1, T2, T3), one session a week, using videotape. Two contents of interactions were also measured: antisocial and normative stories, counterbalanced across sessions. Results showed a significant group effect for antisocial talk and its reinforcement, with less antisocial talk within the mixed group condition in comparison to the pure delinquent group condition. The topic of interaction was also observed as a predictor of antisocial talk, with less normative interactions and more antisocial talk associated with antisocial topics. Finally, time moderated some relations between experimental groups and talk. We conclude with a discussion of the implications of this work for future research on deviancy training processes. Aggr.

The authors' goal was to identify the control mechanisms used by long jumpers (N = 6) to precisely position their foot at the board. In addition to the intertrial method usually used in previous research, an original method based on a trial-by-trial analysis was also implemented. If the approach to the board in long jumping encompasses two distinct sequences separated by a key step that marks the initiation of visual control, then a trial-by-trial analysis should reveal those sequences, regardless of the amount of adjustment: The step number at which regulation is initiated should be the same irrespective of the amount of adjustment. If, in contrast, a perception-action coupling mechanism operates, then the step number at which regulation is initiated should be a function of the amount of adjustment: A linear relation between those 2 variables should emerge. The results of the present study are compatible with continuous control mechanisms based on a perception-action coupling. 相似文献

This study explored the interactive effects of four cognitive variables (perceived expertise of the source, recipients' initial attitudes, number of arguments, and message sidedness) on attitude change. A 2 × 2 × 2 factorial design was used (N = 236 Canadian students): Results showed a positive and significant main effect of initial attitude on attitude change and three significant compensatory effects of independent variables on attitude change: (a) two-sided messages were more persuasive with fewer arguments; conversely for one-sided messages; (b) high expertise compensated for low number of arguments and conversely; and (c) higher expertise was more persuasive in the case of unfavorable recipients and conversely. Results also showed that when the message was one-sided and the number of arguments was large, low expertise was more persuasive than high expertise on initially opposed recipients, which confirms the cognitive response. 相似文献

We assessed decision making in 20 patients newly diagnosed with obstructive sleep apnoea (OSA) and 20 healthy controls with the Iowa Gambling Task (IGT), which evaluates the ability to learn to sacrifice immediate rewards in favour of long‐term gains. A standard neuropsychological battery was administered. Switching scores tended to be lower in patients. Patients persisted in selecting risky decks throughout the IGT, whereas controls behaved normally. Performance was correlated with hypoxaemia. Brain regions underlying decision making may be affected by OSA‐related hypoxaemia. 相似文献

Human expertise at processing faces relies on how facial features are encoded: as a whole template rather than as a sum of independent features. This holistic encoding is less prominent for other-race faces, possibly accounting for the difficulty one encounters in recognizing these faces (the ‘other-race effect’). Here, we tested the hypothesis that the magnitude of holistic face encoding can be modulated by racial categorization of the face. Caucasian participants performed a face-composite task with ‘racially-ambiguous’ face-stimuli (cross-race morphed faces, equally categorized as Asian or Caucasian faces in an independent task). The perceived race of the ambiguous faces was manipulated using adaptation. Experiment 1 showed that identical morphed face-stimuli were processed more holistically when perceived as ‘same-race’ than as ‘other-race’, i.e., following adaptation to ‘other-race’ versus ‘same-race’, respectively. Experiment 2 ascertained that the determining factor in the observed holistic processing modulation was the race of the racially-ambiguous face as perceived, rather than expected, by the participants, which supports the idea that the holistic processing of the face-stimuli was modulated by their race-categorization at the perceptual level. 相似文献
