Texto completoThis doctoral work aims at analyzing the role of motor-perceptual interactions in the visual perception of human movements. Most of studies showed that recognition of human movements was influenced by motor competences, whereas others on the contrary showed dissociation between motor abilities and perception. The aim of our research was to specify the implication of the motor competences in the visual perception of this type of movement. The experiment consisted in analyzing the perceptual preferences for locomotion movements and for morphocinetic movements (elliptical, circular) and the visual perception of the illusion of uniform velocity, which is observed in elliptical movements, in populations presenting quasi-null or variable motor competences (newborn babies, young children aged from 5 to 10 years). These experiments included movements respecting or not the motor constraints imposed by our skeleton (locomotion) and movements whose kinematics conform or not to the motor rules (two-third power law). The principal results indicate that newborns are able to discriminate human movements and are sensitive to the kinematics rules of motor production. Moreover, in the task of perceptual judgment a shift appear between motor competences and perceptual competences in children. Indeed, the phenomenon of the illusion of uniform velocity is more important in the young children and tends to decrease with the age. These findings suggest that the perceptual preferences and judgments do not fully depend on motor competences of the subjects. Taken together, these findings propose that visual perception of the human movements would not systematically imply an intervention of the motor system as stipulate motor theories of perception
Spriet, Céline. "The development of visual object categorization". Electronic Thesis or Diss., Lyon 1, 2024. http://www.theses.fr/2024LYO10231.
Texto completoVisual object categorization is at the interface between "seeing" and "thinking". Evidences from functional MRI (fMRI) studies have described an organization of the ventral stream by visual categories, especially between animate and inanimate entities, that decomposed into finer-grained distinctions. How does this specific organization come about in humans? This thesis presents a set of 4 studies addressing this issue. First, I will hypothesize that the first categories infants represent are constrained by these dimensions organizing object representation in the visual cortex (chapter 3) and study the role of brain maturation and experience in this representation (chapter 4). Then, I will investigate how the speed of presentation influences the animate/inanimate categorization in the first year of life and in adulthood (chapter 5), and what visual features act in this categorization in adults (chapter 6). Results show that infants will first be attracted by non-categorical visual features such as the size of stimuli, before completely relying on categorical features, representing first the animate and inanimate entities. This transition is essentially limited by the brain maturation. This first big categorization gets faster and faster with age, and can be based on low-level visual features, although the more features available, the better the categorization. I suggest that the brain maturation help infants to represent more and more visual features when growing up, allowing them to represent more (finer-grained) categories. This maturation also elicit an acceleration of the representation of the big animate/inanimate categorization with age. Part of this big categorization is actually already possible based on lower-level visual features that covariate with the categories, but adults’ behavior gets influenced by categories only when enough features are presented in the image

Texto completoThis dissertation concerns the visual perception of human motions, more precisely, the importance of motor processes in perceptual processes. Perception-action relationships were analysed in children from ages 7 to 11. This dissertation aimed at showing that the perception of human movement depends, at least to a certain extent, on the individual's own motor experience. The first part of experiments concerns the visual perception of pointing, tansport and grasping movements,in adult's production. The children's task was to predict the size of the target pointed or which the grasped object was displaced and the weight of object grasped or displaced. The second part of experiments concerns motor sequence, with two successive movements : grasping a glass to throw it or to displace il, pointing successively two target, the second target was small or large, writing a cursive two digrams. The movement presented on a computer screen, presented the first component of a sequential gesture. The task of children was to predict the forthcoming gesture by using the kinematic information provided by the first movement component. At the end of the experiment, subjects were asked to produce movements perceived. Results show that perceptual performance of children depends on the observer's motor competence. This research supports the idea of a strong link between perceptual and motor processing : level of motor control development has an effect on the perception of human motions

Texto completoVisual habituation is often considered as linked to information processing, but very few studies have emphasized the relations. Our work has tried to define the relations between visual habituation and information processing. At the end of our experiments, it clearly appears that informaiton processing is achieved before habituation is reached. Habituation can then be considered as involving two successive operations, the first during which information is encoded and a representation made, the second one during which the perceptive imput is compared with the preceeding mnemonic trace, and information recognized as the same. Habituation shows the sam two operations at 3 and 5 months

Texto completoIt is suggested that the association of visual and cephalic systems may predict the eye-head coordination. No research has explored preterm's visuo-cephalic activity. The focus of this study was preterm's visuo-cephalic activity in two tasks : a pursuit and a peripheral detection task. 51 preterms infants, born at 32 weeks, were observed at 37 weeks in a semi vertical position. Four groups of preterms were observed either in one or both conditions : "head fixed" and "head free". Results show that preterm can follow a target moving horizontally at eye level and at a 30 cm distance. The pursuit covers 20 to 25 of the target's total course. Evenmore peripheral detection is observed when the target appears within a 30 angle. Eye displacements were predominantly saccadic in both tasks. Comparison of visual activity between conditions show that preterms perform better in "head fixed" than in "head free" condition. In the latter, two forms of pursuit are observed : a response of ocular pursuit and a response of ocular pursuit accompagnied by a cephalic movement oriented in the same direction. This "ocular-cephalic" pattern of response is characterized by an ocular localization followed by an accelerated cephalic movement

Texto completoThe purpose of this thesis is to study the origins of the relations between perceptual systems such as touch and vision, and the development of their relations during the first year of life. The problem of the unity of senses at birth is old. This question has been answered to in two different ways : prehension of visual object and intermodal transfer or multimodal exploration. Prehension is a relation between the visual sense and the tactual motor system whereas intermodal transfer and multimodal exploration is a relation between senses. The two fields were studied separately until now and it became necessary to bring them together in order to have a complete view of the different relations between perceptual systems which organize our behaviour from birth. A complete analysis of the litterature in the two fields and our own experiments on intermodal transfer may suggest an early unity of the systems at birth. However, this unity is fragile in prehension and a reorganization of behaviour is observed which may be attributed to the development of the tactual motor system. The unity is established between sensory modes but the relations between vision and touch are not reversible at each age. This lack of reversibility may be attributed to the different speeds of the development of the two systems. We ask the question of the stages of cognition that the infants construct in the first year from perceptual and motor organization
