Abstract

[Visual Perceptive Capacities of 4 to 5 Days Old Infants)

 

The aim of this study is the testing of a population of Belgian term newborn babies 4 to 5 days old. using a technique devised by R Fantz. In this study, the fixation time of the test objects determines the attention of the baby for lest objects varying in degree of pattern types. The test objects tend to discriminate perception segregation of patterns over dull background, of forms of patterns (complexity regularity size) and of differentiation between rectilincarity and curvilinearity. Results treated by variance analysis and means show that at this early age : 1. infants look longer to broadly striped objects than plain ones (Tables 1 & 2): 2. the large patterns are fixed longer than the small ones (Tables 1 & 2): 3 infants look longer to rectilincarity than to curvilinearity (Tables 1 & 2): 4 the complexity pair is fixed longer by the majority of infants, with a slight ‘preference’ shown by certain subjects for the simplest patterns; 5. the ‘face' pair is ‘preferred’ to the complex pair; 6. babies usually present a left asymmetry (Tables 1 & 2). In this work preliminary to a study of infants from 4 days to 3 months (belonging to different pathological groups) our results on the whole confirm those obtained by other workers using the same type of technique and patterns testing the same parameters except in regard to left asymmetry. For this a manipulation factor may be responsible and is being investigated. Four to 5 days old infants differentiate pattern types, but the lengthening of fixation time toward certain test objects may not be the result of a preference but rather a submission to the physical properties of the stimuli due to central nervous system characteristics from which the infants cannot escape.
