In the current study, we examined the developmental course of the perception of non-native tonal contrast. We tested 4, 6 and 12-month-old Dutch infants on their discrimination of Chinese low-rising tone and low-dipping tone using the visual fixation paradigm. The infants were tested in two conditions that differed in terms of degree of…

Purpose: This preliminary investigation explored potential cognitive and linguistic sources of variance in 2- year-olds' speech-sound discrimination by using the toddler change/no-change procedure and examined whether modifications would result in a procedure that can be used consistently with younger 2-year-olds. Method: Twenty typically…

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

Activities geared to meet the needs and capabilities of low functioning residents (mental age 2 to 4 years) of an institution who were not benefiting from other language development material are given. The lessons incorporate material from other programs to form a series of 212 daily lesson plans. Each lesson is structured and self-explanatory and…

The Auditory Discrimination in Depth (ADD) program, an oral-motor approach to beginning reading instruction, trains first grade children in auditory skills by a process in which language and oral-motor feedback are used to integrate auditory properties with visual properties. This emphasis of the ADD program makes the child's perceptual…

This curriculum guide provides a variety of activities to develop perceptual skills in young children. Activities in the following areas are provided: (1) motor skills--awareness of self, gross motor, fine motor, orientation in space, eye motor; (2) auditory skills--attention, listening, discrimination, imitation and articulation, auditory…

Several studies have begun to investigate the claim that children can make most phonological discriminations when they begin to speak. This paper investigates how well children aged 2;3 to 2;11 can discriminate between pairs of minimally different real words, and it shows that the results are affected by how well the children know the words. It is…

The Institute for Developmental Studies (IDS) is engaged in research aimed at specifying what the academic handicaps of deprived children are, what causes these handicaps, and what can be done to overcome them. This IDS report on their research and evaluation program is divided into two sections. The first, "Summaries of Basic Research, Applied…
