Purpose: Infants have a good ability to detect brief silent gaps between 2 short identical sound markers (within-channel gap detection), with thresholds between 2 and 11 ms. The present experiment traces the development of temporal resolution for between-channel gaps (i.e., gaps delineated by spectrally disparate markers). This ability appears…

Previous research indicates that children from lower socioeconomic backgrounds show deficits in aspects of attention, including a reduced ability to filter irrelevant information and to suppress prepotent responses. However, less is known about the neural mechanisms of group differences in attention, which could reveal the stages of processing at…

Young infants discriminate both native and nonnative phonetic contrasts, but 10- to 12-month-olds and adults fail to discriminate some nonnative contrasts. To explain this, Best, McRoberts, and Sithole (1988) hypothesized that at the age of 10-12 months, a phonological influence begins by means of which nonnative sounds are assimilated to native…

An appoach to the use of sound in computer interfaces, proposed in this article, emphasizes the role of sound in conveying information about the world to the listener. This approach argues that auditory icons, i.e., caricatures of naturally occurring sounds, provide a natural way to represent dimensional data as well as conceptual objects in a…

Phonological fusion occurs when the phonemes of two different speech stimuli are combined into a new percept that is longer and linguistically more complex than either of the two inputs. The present article is an investigation of the conditions necessary and sufficient for fusion to occur. (Editor/RK)

Research is reported which examined the effect of various factors on the frequency of phonological responses. Phonemic order and location of clusters within a syllable affected fusion. Initial stop-liquid clusters fused readily; final liquid-stop clusters rarely fused. Some subjects fused on most or all trials; others fused less frequently.…

Definitions and specific breakdowns of four (auditory reception, visual sequential memory, verbal expression, and auditory closure) of the 12 language areas of the new Illinois Test of Psycholinguistic Abilities (ITPA) are presented. Auditory reception is defined as the ability to understand the meaning of materials or stimuli that are heard and…

Two experiments are reported in which cardiac habituation and dishabituation to pure tone stimuli were studied in well and malnourished Guatemalan infants. In both studies the magnitude of the orienting response was found to be attenuated or completely absent in infants suffering from nutritional insult. The findings were taken as evidence of a…

To measure the symmetry of adult categorical phoneme perception, 10 adult male undergraduate students enrolled in an introductory psychology class were the subjects for this study as part of their course requirements. The stimuli used in this study were prepared at Haskins Laboratories by means of a parallel resonance synthesizer and computer. The…

Designed to aid in developing auditory perception, this manual provides a program of remediation for children at the fourth through sixth-grade level. The book is divided into two sections. The first consists of seventy-five essays, each written at three levels of difficulty. The level most appropriate for the student is determined and is used for…

The items in this annotated bibliography include studies, journal literature, USOE-sponsored research, and the conference proceedings of the International Reading Association, covering the years 1950 to 1969. Part I is devoted to "Audition" which encompasses reports based on all aspects of listening and its relationship to reading, and "Auditory…
