Attention visuelle et distractibilite chez des bebes de 3 a 5 mois.

Studied the development of sensitivity to distractors in 35 male and 16 female infants (aged 3 and 5 mos) in France. Stimuli consisting of irregular forms of different colors were presented in the center of a computer screen. A peripheral distractor, consisting of 4 yellow bars, was placed to the right of the central image after 4 secs fixation. The results were evaluated according to age, latency, total duration of fixation on central object, number of fixations on center, and fixation. An ANOVA and other statistical tests were used. The results show long latency periods in 3-mo-old infants, which may correspond to difficulty in disengaging fixation, and short latency periods and habituation to distractors in 5-mo-old infants. Implications for research on the development of visual fixation and habituation patterns in infants are discussed. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
