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 causes of organizational citizenship behavior: a motivational analysis.

This study addressed the role of motives in organizational citizenship behavior (OCB). Three motives were identified through factor analyses: prosocial values, organizational concern, and impression management. Scales that measured these motives and other variables known to covary with OCB were administered to 141 municipal employees and were correlated with self-, peer, and supervisor ratings of 5 aspects of OCB. Relative to the other motives, prosocial values motives were most strongly associated with OCB directed at individuals, and organizational concern motives were most strongly associated with OCB directed toward the organization. Each of the motives accounted for unique amounts of variance in OCB. The results suggest that motives may play an important role in OCB.     

Food rejection and the development of food category-based induction in 2–6 years old children

We studied children’s inductive inferences within the domain of food categories. There has so far been little research on inductive reasoning about food among children, despite the theoretical and practical importance of knowing what knowledge children bring to the table and how they use it. We tested the hypotheses that children’s food category-based induction performances and their food rejection are negatively correlated, and that these performances are influenced by the colour typicality of the food items. We recruited 126 children aged 2–6 years, and administered a category-based induction task. Participants were successively shown 8 sets of three pictures containing one target picture (a vegetable) and two test pictures (a vegetable dissimilar in colour to the target picture and a fruit similar in colour to the target picture). For each set, participants were told a novel property about the target picture and asked to generalise this property to one of the two test pictures. Additionally, the parents of each child filled out a questionnaire about his or her food rejection tendencies. Results on accuracy (i.e. if participants generalised the properties according to category membership, not perceptual similarity) provided the first empirical evidence in favour of a negative relationship between children’s food rejection and food category-based induction.     

Effects of active and passive EMG biofeedback training on performance of motor and cognitive tasks.

The goal of this study was to compare the effects of general relaxation (passive group) and neuromuscular tension control (active group), both using EMG biofeedback techniques, on the performance of memorization, simple reaction time, and rotary pursuit. 18 subjects were given five consecutive daily sessions of training or were placed under control conditions, after which their performance on these various tasks was evaluated. Results indicate that control of neuromuscular tension seemed to facilitate performance on all tasks over that of the control group. Except for simple reaction time, there was no difference between the "active" and "passive" groups. The results are interpreted in terms of factors in selection of subjects and experimental conditions.     

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.
