Since birth, infants develop the ability to perceive a wide range of intersensory relations among various kinds of amodal temporal information. This study addresses the development of the ability to perceive duration-based intersensory relations. Three groups of infants, four, seven and 10 months old, participated in two trials of an intersensory…

Sensorimotor integration is an unconscious process of the brain incorporating multiple senses and movement. This review aimed to synthesize the literature on the role of visual-motor integration in language learning, whether spoken or signed, for deaf and hard of hearing (D/HH) children. Nineteen peer-reviewed studies published between 1980 and…

Young infants perceive an object's trajectory as continuous across occlusion provided the temporal or spatial gap in perception is small. In 3 experiments involving 72 participants the authors investigated the effects of different forms of auditory information on 4-month-olds' perception of trajectory continuity. Provision of dynamic auditory…

The author is naturally a kinesthetic learner. As a child she was steeped in the wilds of seashore, fields, and woods in which she was free to roam, explore, and imagine in a deeply sensual, movement-oriented world. Because of these first experiences of freedom of movement and spontaneity in the highly intense natural world, she found the…

Despite external changes such as those of magnitudes, the functional properties of the visual system also improve with increased age. According to Jean Piaget's centration/decentration theory, the process of perceptual development might continue until adulthood and even after. However, perceptual development should not be understood in all of its…

The structure and function of the nervous system as it puts us into contact with our environment is described. Section 1 presents a detailed discussion of the structure of the brain, drawing an analogy to a computer, and discusses the sensory input function. The transport system is then explained in a description of the transmission of sensory…

Ten normally speaking children, 10 having mild misarticulations, and 10 having severe misarticulations, aged seven-eight, were administered unisensory and bisensory processing tasks. Results showed that misarticulating children obtained lower scores than normal children on all bisensory tasks and had larger decrements from unisensory to bisensory…

Recent studies have reported that preverbal infants are able to discriminate between numerosities of sets presented within a particular modality. There is still debate, however, over whether they are able to perform intermodal numerosity matching, i.e. to relate numerosities of sets presented with different sensory modalities. The present study…

Relevant orientation and mobility (OM) skills for visually impaired infants foster sensory, motor, and conceptual development. OM personnel need to consider alternative teaching models, personnel preparation needs, sensory aids issues, and research issues. (DB)

A study used the Three-Interval Forced-Choice Test of Speech Pattern Contrast Perception (THRIFT) to examine sensory-level speech-perception performance under the input modalities of hearing alone, speech-reading alone, and the two combined in 44 children (ages 5-10). Within each condition there were significant influences of age on performance…

The purpose of this study was to see if a change in environment affected the rate of sensorimotor development in infants. First a control group of institutionally-reared infants aged 1 to 6 months was observed to determine average age of visually directed reaching, visual exploration, visual accommodation, and the blink response. Then the…
