Speech production, both overt and covert, down-regulates the activation of auditory cortex. This is thought to be due to forward prediction of the sensory consequences of speech, contributing to a feedback control mechanism for speech production. Critically, however, these regulatory effects should be specific to speech content to enable accurate speech monitoring. To determine the extent to which such forward prediction is content-specific, we recorded the brain's neuromagnetic responses to heard multisyllabic pseudowords during covert rehearsal in working memory, contrasted with a control task. The cortical auditory processing of target syllables was significantly suppressed during rehearsal compared with control, but only when they matched the rehearsed items. This critical specificity to speech content enables accurate speech monitoring by forward prediction, as proposed by current models of speech production. The one-to-one phonological motor-to-auditory mappings also appear to serve the maintenance of information in phonological working memory. Further findings of right-hemispheric suppression in the case of whole-item matches and left-hemispheric enhancement for last-syllable mismatches suggest that speech production is monitored by 2 auditory-motor circuits operating on different timescales: Finer grain in the left versus coarser grain in the right hemisphere. Taken together, our findings provide hemisphere-specific evidence of the interface between inner and heard speech.
The significance of the problem of parental involvement in children’s education has to do with the proven positive effects of parental involvement in school on children’s wellbeing. However, no universal comprehensive idea of family involvement types and strategies has been developed so far, and the jury is still out on the efficiency of various family-school interactions in use today. This study is designed to shed light on the forms of parental involvement, which may differ depending on family, student and school characteristics. The study seeks to operationalize the concept of parental involvement, describe parental involvement based on the findings of a large-scale survey, evaluate the dependence of parental involvement on family, student and school characteristics, suggest models to predict the level of parental involvement half way through elementary school, and develop recommendations for schools. Parents of 1,447 students from Krasnoyarsk and Kazan middle schools involved in the iPIPS project were surveyed twice using the same questionnaire, first as their children became first-graders and then at the beginning of the third grade. The survey contained questions on family demographic characteristics, parents’ at-home and at-school involvement, and parental satisfaction with school communication. It was established that parental perception of school communication climate is a much more important predictor of thirdgrade parent involvement in school than family sociodemographic characteristics or the level of child development assessed at baseline. On the whole, the results obtained do not confirm the benefit of using universal strategies to encourage parental involvement.
especially impaired on regular past-tense forms like played, whether the task requires production, comprehension or even the judgement that "play" and "played" sound different. Within a dual-mechanism account of inflectional morphology, these deficits reflect disruption to the rule-based process that adds (or strips) the suffix -ed to regular verb stems; but the fact that the patients are also impaired at detecting the difference between word pairs like "tray" and "trade" (the latter being a phonological but not a morphological twin to "played") suggests an important role for phonological characteristics of the regular past tense. The present study examined MEG brain responses in healthy participants evoked by spoken regular past-tense forms and phonological twin words (plus twin pseudowords and a non-speech control) presented in a passive oddball paradigm. Deviant forms (played, trade, kwade/kwayed) relative to their standards (play, tray, kway) elicited a pronounced neuromagnetic response at approximately 130 ms after the onset of the affix; this response was maximal at sensors over temporal areas of both hemispheres but stronger on the left, especially for played and kwayed. Relative to the same standards, a different set of deviants ending in /t/--plate, trait and kwate--produced stronger difference responses especially over the right hemisphere. Results are discussed with regard to dual- and single-mechanism theories of past tense processing and the need to consider neurobiological evidence in attempts to understand inflectional morphology.
We present a database of uvular consonant subsystems of indigenous languages of the Caucasus from all branches (Northwest Caucasian, East Caucasian and Kartvelian). Data for the database were collected from existing language descriptions and field work. All in all, 39 languages were analyzed. This database allows us to systematically compare the inventories of uvular consonants in the Caucasian languages and create a predictive model for the co-occurrence of particular uvular consonants.
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
This article describes the expierence of studying factors influencing the social well-being of educational migrants as mesured by means of a psychological well-being scale (A. Perrudet-Badoux, G.A. Mendelsohn, J.Chiche, 1988) previously adapted for Russian by M.V. Sokolova. A statistical analysis of the scale's reliability is performed. Trends in dynamics of subjective well-being are indentified on the basis the correlations analysis between the condbtbions of adaptation and its success rate, and potential mechanisms for developing subjective well-being among student migrants living in student hostels are described. Particular attention is paid to commuting as a factor of adaptation.
