A total of 60 infants of 7 weeks of age were tested in a habituation-dishabituation looking procedure to determine if they could discriminate between infant-directed talk (IDT) and adult-directed talk (ADT) uttered by the same speaker. One group of 12 infants was habituated to a female speaker's ADT and dishabituated to the same speaker's IDT,…

A forced-choice observer-based testing procedure was used to determine pure-tone hearing thresholds for 2- to 4-week-old infants. Stimuli were 500-ms tone bursts of 500, 1,000, or 4,000 Hz with 500-ms intervals between tone bursts. Stimuli were presented monaurally by means of an insert earphone. Each 15-s trial consisted of 5 tone bursts,…

Children hear music in the background of a large variety of situations and activities. Throughout development, they acquire knowledge both about the syntactical norms of tonal music, and about the relationship between musical form and emotion. Five to six-year-old children heard a story, with a background "happy", "sad" or no…

The focus of this research is to determine how soon and to what extent infant abilities are influenced by listening experience. Fourteen English-learning infants and fourteen Spanish-learning 6-8 month old infants participated in a first experiment; eight additional English and Spanish-learning infants participated in a second experiment. Infants…

Studies (2) of auditory memory performance are reported. Children were asked to recall material which permitted different language habits to be used (structural, and meaningful). Lower socio-economic status (LSES) Negro children performed more like their middle socio-economic status white (MSES) counterparts on non-contingent strings. When…

In two experiments Ss (16 undergraduate students in the first, 14 in the second) listened to a sentence containing a brief tone, then wrote out the sentence and marked the location of the tone. (Author/SBH)

Twenty-five male stutterers and 25 male non-stutterers (5-13 years old) matched by age and speaking task, read or recited under normal and 113-, 226-, 306-, 413-, 520-msec. delayed auditory feedback conditions. (Author)

The principal objective of this study was to evaluate, in 21 severely hearing impaired children (9 to 12 years old), the relative effects of length of stimuli by closed set identification tasks. (Author/SBH)

Compares the rates of forgetting of five-item sequences of acoustically similar and dissimilar consonants and words in the absence of proactive and retroactive interference in order to test whether within sequence similarity rather than stimulus length would have a greater influence on retention. (Author/RK)

The relatedness of four elements (tone, white noise, click, and a buzz) making up a recycled pattern was varied to determine the effects of streaming (sounds that break into separate channels) on the ease of correctly ordering the elements. Results suggest the organization of elements into streams by similarity supplants the organization by…

Infants, preschoolers, and adults were tested to determine the shortest time interval at which they would respond to the precedence effect, an auditory phenomenon produced by presenting the same sound through two loudspeakers with the input to one loudspeaker delayed in relation to the other. Results revealed developmental differences in threshold…

Three studies were designed to examine infants' bisensory responsiveness to temporally modulated stimulation by varying frequency while keeping intensity constant, by varying both frequency and intensity together, and by varying intensity while keeping temporal frequency constant. Findings indicate that sound influences visual preferences via…
