Jeu moteur et acquisition de la coordination bimanuelle chez les nourrissons âgés de 12 à 24 mois.

Abstract

Our study is entitled: Motor play and the acquisition of bimanual coordination in children between 12 to 24 months. It is situated in the psychomotor axis of infant development, and aims at testing the effect of motor play in the acquisition of bimanual coordination. To this end, a specialised literature was compiled around the central themes of the study. This study used Claparède's (1905) theory of motor play, which enabled us to bring out the problem wish is the difficulty of the complementary and asymmetrical use of the two hands by children between12 and 24 months. This study was carried out on 10 Cameroonian children between 12 to 24 months in the city of Yaounde, Yaounde 6 division, of both sexes from the Câlinours Day-care Center. To collect the data, we developed a 3-point numerical scale inspired by the Likert model (1936). The data were processed using the SPSS software, having as statistical tools the Student's t-test, the Shapiro- Wilk normality test and the Wilcoxon signed-rank test. After processing the data, it emerged that motor play manipulation promotes the acquisition of bimanual coordination in children from 12 to 24 months, as shown by the following results: Pairwise differences are normally distributed, as shown by the Shapiro- Wilk test: 0.885, p=0.150. A paired two-sample TEST-T showed that overall mean performance after simulation increased (M = 2.541; SD = 0.082) compared to the initial performance (M = 2.247; SD = 0.103). This mean difference (M = - 0.294, SE = 0.034) has shown to be significant: T (9) = - 8.660, p= <0.001 so we can reject H0 and assert that the mean difference is different from 0. Cohen's d (-2.739) suggests a large effect.
