The Perceptual Weighting Of Speech-Related Acoustic Cues For 3 & 1/2-Year-Old Children Differs From That Of Adults: Results Using Natural And Synthetic Stimuli, Carol J. Manning
The Perceptual Weighting Of Speech-Related Acoustic Cues For 3 & 1/2-Year-Old Children Differs From That Of Adults: Results Using Natural And Synthetic Stimuli, Carol J. Manning
Student Work
Previous studies have found that children’s judgments of syllable-initial /s/ and / ∫ / are more related to the vocalic F2 transition and less related to the fricative-noise spectrum than are adults’ judgments [Nittrouer & Studdert- Kennedy, JSHR, 30 (1987); Nittrouer, J. Phon., 20 1992]. These results have been taken as evidence that young children organize linguistic input in units more closely approximating syllable size than phoneme size. Furthermore, such results have led to a model of speech development proposing that children’s weighting of the acoustic cues for phonemic categories changes as they gain linguistic experience, with a general shift …
The Effects Of Child-Directed Speech Vs Adult-Directed Speech On Attention And Categorization In Prelinguistic Infants, Jean M. Schumacher
The Effects Of Child-Directed Speech Vs Adult-Directed Speech On Attention And Categorization In Prelinguistic Infants, Jean M. Schumacher
Student Work
The facilitative role of linguistic input on nonlinguistic categorization is frequently explained in terms of children's attention to uniquely linguistic forms such as words. In the three experiments reported here, 15-month-old infants were familiarized to visual stimuli in the context of hearing either adult-directed speech (ADS) or child-directed speech (CDS) during visual fixations. Categorization was successful with CDS and ADS input when accumulated attention was not constrained (Experiment 1). Moreover, there were no differences in accumulated attention as a function of input type. When attention was constrained to 90 seconds (Experiments 2 and 3), ADS input disrupted categorization more for …
