LOCALISATION ET RECHERCHE DE L'OBJET CACHE CHEZ L'ENFANT DE 16 A 24 MOIS

Three experiments were conducted, in order to investigate the spatial organization in children between 16 and 24 months. All experiments were based on a task requiring a search for an object with three possible hiding places. Between hiding and search, the relative positions of subject and apparatus were modified. In experiment 1, two kinds of rotations were compared: rotations involving the child himself versus rotations of the apparatus. Performances were better in the latter case. Experiments 2 and 3 showed that the three spatial positions were not equivalent for subjects. In particular, the proximal position relative to the subject was clearly privileged when the rotations were done in a horizontal plane. However, this privilege did not appear when the rotations were done in a frontal plane.     

Allophonic mode of speech perception in dyslexia

Perceptual discrimination between speech sounds belonging to different phoneme categories is better than that between sounds falling within the same category. This property, known as "categorical perception," is weaker in children affected by dyslexia. Categorical perception develops from the predispositions of newborns for discriminating all potential phoneme categories in the world's languages. Predispositions that are not relevant for phoneme perception in the ambient language are usually deactivated during early childhood. However, the current study shows that dyslexic children maintain a higher sensitivity to phonemic distinctions irrelevant in their linguistic environment. This suggests that dyslexic children use an allophonic mode of speech perception that, although without straightforward consequences for oral communication, has obvious implications for the acquisition of alphabetic writing. Allophonic perception specifically affects the mapping between graphemes and phonemes, contrary to other manifestations of dyslexia, and may be a core deficit.     

Adaptation and Validation of the Inventory of Everyday Hassles of Students in Romanian

Students who are admitted to university have to get accustomed to and then assimilate the codes of their new life, progressively acquiring a new social status and a new identity. There is no tool in Romanian to measure students’ perceived stress. This article presents the results of a series of five studies to validate a scale of Everyday Hassles of Romanian Students. Seven hundred and seventy seven Romanian students enrolled in a university program either in Engineering or the Humanities participated in the studies. The results revealed that the questionnaire of Everyday Hassles of Romanian Students had a six-factor structure. It had acceptable reliability and validity values. With regard to reliability, its scales showed high levels of internal consistency and temporal stability over a time span of three weeks. The results seem equally encouraging in terms of validity. Further investigations, particularly studies of convergence and discrimination, are required to identify more precisely the construct validity of the tool.     

Criterion Validity of the Rorschach Developmental Index With Children

The Rorschach Developmental Index (DI) is a composite measure of psychological development. The aim of this study was to examine the criterion validity of the DI by investigating its relationship with age, nonverbal intelligence, and the impact of institutionalization in a sample of Brazilian children. The sample included 231 children, ages 7 to 11, who were either living with their families or in an institutionalized setting. The results indicated that the DI is strongly associated with nonverbal intelligence. Multiple regression analysis revealed that 71% of the variability in the DI was associated with nonverbal intelligence, whereas age explained only 2%. Moreover, the DI scores and nonverbal intelligence scores were significantly lower for children living in institutionalized settings. The DI appears to be effective in assessing various levels of psychological development, especially when expressed in cognitive ability. The DI was developed in the United States, and this study suggests that the DI can be adapted to diverse cultures, regions, or languages.     

The Spiritual Well-Being of Elderly People: A Study of a French Sample

The aim of our research was to identify predictors of the spiritual well-being of elderly people. More specifically, we postulated that subjective well-being and its components would be predictors of spiritual well-being, and more so than age and health status. We invited 133 people aged 60–95 to complete a questionnaire that included the French adaptation (Velasco and Rioux in Revue Canadienne des Sciences du Comportement 41(2):102–128, 2009) of Paloutzian and Ellison’s (Loneliness: A sourcebook of current theory, research and therapy, Wiley-Interscience, New York, 1982) Spiritual Well-Being Scale, Ryff and Essex’s (Psychol Aging 7:507–517, 1992) Psychological Well-Being Scale (translated by Lapierre and Desrochers 1997), Salamon and Conte’s (Meas Eval Guid 15(3):194–200, 1982) Life Satisfaction in the Elderly Scale (validated by Rousseau and Dubé in 1993), and the French version (Blais et al. in Can J Behav Sci 21:210–223, 1989) of Diener et al. (J Pers Assess 49:71–75, 1985) Satisfaction with Life Scale. The results only partially confirm our hypothesis, because only satisfaction with life as a whole and two items in “Life Satisfaction in the Elderly Scale” make it possible to predict the spiritual well-being of elderly people. Moreover, neither health status nor age was found to be a significant predictor of spiritual well-being. This research helps understand better the links between the concept of spiritual well-being and that of subjective well-being of elderly people and could contribute to the development of a tool that could take into account the spiritual well-being of elderly people, whether they be believers, agnostic, or atheist.     

Discrimination of speech sounds by children with dyslexia: comparisons with chronological age and reading level controls

Previous studies have shown that children suffering from developmental dyslexia have a deficit in categorical perception of speech sounds. The aim of the current study was to better understand the nature of this categorical perception deficit. In this study, categorical perception skills of children with dyslexia were compared with those of chronological age and reading level controls. Children identified and discriminated /do-to/ syllables along a voice onset time (VOT) continuum. Results showed that children with dyslexia discriminated among phonemically contrastive pairs less accurately than did chronological age and reading level controls and also showed higher sensitivity in the discrimination of allophonic contrasts. These results suggest that children with dyslexia perceive speech with allophonic units rather than phonemic units. The origin of allophonic perception in the course of perceptual development and its implication for reading acquisition are discussed.     

Development of phonological and orthographic processing in reading aloud,in silent reading,and in spelling: a four-year longitudinal study

The development of phonological and orthographic processing was studied from the middle of Grade 1 to the end of Grade 4 (age 6; 6-10 years) using the effects of regularity and of lexicality in reading aloud and in spelling tasks, and using the effect of pseudohomophony in a silent reading task. In all the tasks, signs of reliance on phonological processing were found even when indicators of reliance on orthographic processing appeared. Multiple regression analyses were conducted to determine which early skills predict later reading achievement. Pseudoword and irregular word scores were used as measures for phonological and orthographic skills, respectively. Only middle of Grade 1 phonological reading skills accounted for independent variance in end of Grade 4 orthographic skills. Conversely, from the middle to the end of Grade 1, and from the end of Grade 1 to the end of Grade 4, both orthographic and phonological skills accounted for independent variance in later orthographic skills. In the prediction of phonological skills, only the unique contribution of earlier phonological skills was significant. Thus, phonological and orthographic processing appear to be reciprocally related, rather than independent components of written word recognition. However, very early reliance on the phonological procedure seems to be the bootstrapping mechanism for reading acquisition.     

MANULEX: a grade-level lexical database from French elementary school readers.

This article presents MANULEX, a Web-accessible database that provides grade-level word frequency lists of nonlemmatized and lemmatized words (48,886 and 23,812 entries, respectively) computed from the 1.9 million words taken from 54 French elementary school readers. Word frequencies are provided for four levels: first grade (G1), second grade (G2), third to fifth grades (G3-5), and all grades (G1-5). The frequencies were computed following the methods described by Carroll, Davies, and Richman (1971) and Zeno, Ivenz, Millard, and Duvvuri (1995), with four statistics at each level (F, overall word frequency; D, index of dispersion across the selected readers; U, estimated frequency per million words; and SFI, standard frequency index). The database also provides the number of letters in the word and syntactic category information. MANULEX is intended to be a useful tool for studying language development through the selection of stimuli based on precise frequency norms. Researchers in artificial intelligence can also use it as a source of information on natural language processing to simulate written language acquisition in children. Finally, it may serve an educational purpose by providing basic vocabulary lists.
