AbstractThe aim of this study was to outline an age-dependent range of posturography measures obtained from healthy children. One hundred and fifty healthy 4–18-year-old children underwent video Head Impulse Test and static posturography testing. Surface, length and power spectra values were compared between each group of pupils and 32 healthy adults. As well as a significant (p?<?0.025) increase in surface and length, when compared to healthy adults, increased values within the low/middle frequency domain and within the high frequency domain were also observed in 4–13 and 4–7-year-old children, respectively. In conclusion, although the nature of postural control development remains largely undetermined, this study represents a first attempt to outline an age-dependent normal range of the relative contribution of inputs in typically developing children. 相似文献

The performance of 14 poor readers on an audiovisual speech perception task was compared with 14 normal subjects matched on chronological age (CA) and 14 subjects matched on reading age (RA). The task consisted of identifying synthetic speech varying in place of articulation on an acoustic 9-point continuum between /ba/ and /da/ (Massaro & Cohen, 1983). The acoustic speech events were factorially combined with the visual articulation of /ba/, /da/, or none. In addition, the visual-only articulation of /ba/ or /da/ was presented. The results showed that (1) poor readers were less categorical than CA and RA in the identification of the auditory speech events and (2) that they were worse in speech reading. This convergence between the deficits clearly suggests that the auditory speech processing difficulty of poor readers is speech specific and relates to the processing of phonological information. 相似文献

The question of whether Dutch listeners rely on the rhythmic characteristics of their native language to segment speech was investigated in three experiments. In Experiment 1, listeners were induced to make missegmentations of continuous speech. The results showed that word boundaries were inserted before strong syllables and deleted before weak syllables. In Experiment 2, listeners were required to spot real CVC or CVCC words (C = consonant, V = vowel) embedded in bisyllabic nonsense strings. For CVCC words, fewer errors were made when the second syllable of the nonsense string was weak rather than strong, whereas for CVC words the effect was reversed. Experiment 3 ruled out an acoustic explanation for this effect. It is argued that these results are in line with an account in which both metrical segmentation and lexical competition play a role. 相似文献

Two mathematical models of social contingency are examined in terms of their development over the first year of life. The interactions of 53 mothers and their infants were recorded at 6 weeks, 4 months, and 12 months. The infants' gazes at 6 weeks, the mothers' vocal behavior at 6 weeks, and the vocal behavior of the mother and infant at 4 and 12 months were automatically coded in terms of four states. The conditional dependence model and the response effects model were computed for each interaction at each age, and the coefficients of the models were examined as a function of age. The relative success of the models as estimates of moment-to-moment contingency as well as their variations with age are discussed. 相似文献

Counseling in Zimbabwe has a long tradition, dating back to pre‐Colonial times. In the modern context, counseling has evolved through the educational and health care sectors. Since the 1990s, Zimbabwean counselors have advocated for professional recognition, a struggle similar to that of counselors in the United States. In this article, the authors provide a historical view of counseling in Zimbabwe, discuss the current status of and future trends in counseling, and make recommendations for the advancement of the profession. 相似文献

While expectancy-value-cost theory predicts that students' task values play an important part in academic engagement, these associations have rarely been tested in science education and are even less studied in authentic classroom situations. The present study examined to what extent momentary task-values, expectations and costs are associated with students' momentary academic engagement in science classes. Momentary academic engagement was operationalised as energy (give up), dedication (grit) and absorption (flow) components of engagement. Finnish (N = 5891 beeps, 307 students) and Chilean (N = 1931 beeps, 157 students) secondary school students participated in the study using Experience Sampling Method via smartphones. When signalled, students responded to questions via smartphones concerning their momentary task values, expectations, costs and components of engagement in the current activity. The research questions were analysed with multilevel path modelling. The results showed that, for both samples task-values, expectations and costs were related to energy, dedication and absorption components of engagement in science classes. High momentary task-values were positively associated with momentary flow and grit; high momentary expectations were positively associated with high grit and low giving up in both samples; and high momentary challenge showed as increases in feelings of giving up. 相似文献

In the present study, the authors aimed to assess the short- and long-term predictive power of the various components of an emergent literacy model on early writing abilities in a language with a mainly transparent orthography (Italian). Emergent literacy skills were assessed in 72 children (M age = 5.05 years, SD = +/- .03) who were followed longitudinally from preschool to the end of the first grade of primary school. Their early writing abilities (orthographic correctness in writing individual words) and their advanced writing abilities (orthographic correctness in text writing) were tested at the beginning and at the end of the school year. Multiple stepwise and logistic regression analyses were conducted to evaluate the predictive capacities of emergent literacy abilities on early and advanced writing competences. Results show that notational competence is a strong predictor of early writing skills and that phonological competence only has an effect insofar as it is integrated with notational competence. Emergent literacy competences do not significantly predict orthographic errors in advanced text writing. This research allows for reconsideration of the importance of phonological awareness and gives a central role to notational competence in predicting early writing competence. 相似文献

In matters of the mind, the opposition between what is mind-made or inside and natural or outside the mind is bound to misfire. Lindquist et al. build their analysis on a strong contrast between naturalism, which they reject, and psychologism, which they endorse. We challenge this opposition and indicate how adopting psychologism to combat a naturalistic view of emotional mind/brain areas is self-defeating. We briefly develop the alternative view of emotions as mental organs. 相似文献
