If the N1 wave (amplitude component between 80-130 msec) does not serve as an index of an initial stimulus set stage of selection, the N1 amplitudes should be differentiated between channels whether the selection is based on pitch, spatial position, intensity, or cues that lead to an efficient rejection of unwanted information. This study…

The Peterson and Peterson short-term memory paradigm (1959) involves an interpolated task with several potential dimensions from which interference may originate: similarity of items and vocalization. This research assesses the relative interference potency of each on material presented either aurally or visually. (Editor/RK)

Describes a new paradigm that may be appropriate for uncovering speech perceptual codes. Illusory words are detected by blending two dichotic stimuli. The paradigm's design allows for comparison of different speech units by the manipulation of the distribution of information between two inputs. (23 references) (Author/CK)

Reports an experiment contrasting word-onset gating with results when words were gated from their word endings. The study demonstrated a significant recognition advantage for words gated from their onsets. The overall results support the position that the perceptual advantage of word-initial information can be understood within a general…

Argues that Abbott's reservations arise largely from assuming that the term "hearer-new" must be restricted to its original use as defined in Prince (1992). Also argues that if "hearer-new" may be extended to encompass a wider range of "entities" (including events, attributes, etc.) and greater flexibility in its potential applications, then many…

Tests the point of convergence of linguistic information from auditory and visual channels. Compares reaction times for auditory and visual stimuli consisting of sentences, syntactic nonsense strings, random words, and nonwords. Finds that listening and reading processing converge at the word level and that words processed aurally and visually…

Assessed development of auditory selective attention using event-related brain potentials (ERPs) and behavioral measures. Subjects heard tones or consonant-vowel sequences to detect deviant targets. Found that Nd difference (ERP difference between unattended and attended standard) showed effect of selective attention. For both tones and…

Assessed infants' ability to anticipate temporally cued events by presenting trials in which an interesting event was paired with a noise, followed by trials in which the interesting event was omitted. Infants demonstrated anticipatory heart-rate responses to the interesting event and a change in response to the interesting event from general to…

Used data from infants in operant head-turning procedure to examine effects of structure and redundancy of speech context on discovery of two target syllables. Clustering strategy, which presupposes basic element of perception and aggregates these elements to form units, may complement bracketing strategy, which presupposes endpoint cues and…

Children's memory of single infant experience was evaluated. At 6.5 months, infants participated in study of reaching in light and dark for sounding object. Children repeated dark procedure in laboratory when they were either one year or two years older. Older children with infant experience reached and grasped the sounding object significantly…

A study, including research and practice notes by various authors, investigated whether extended training in an acoustically rich environment could enhance the spatial updating ability of 12 adults with congenital blindness. After training, the adults' distance perception from a home-base location and novel locations was superior to a sighted…

Used visual preference technique to examine infants' (mean age 14.8 months) comprehension of two novel words for images of novel objects. Found that infants looked preferentially at images that matched an auditory stimulus and that infants showed learning after about 12 presentations of new words. Results support previous demonstration of rapid…

Three groups of 10 children, ages 8-14 (with autism or receptive developmental language disorder or without disabilities), participated in event-related brain potential experiments. Results suggest that both clinical groups failed to fully process changes in stimulus intensity. Findings are discussed in terms of potential abnormalities in…

A study of two forms of the Auditory Reading Test with 53 elderly participants with normal or low vision and hearing found mild-to-moderate hearing loss did not reduce auditory reading rates as much as expected. Participants with low vision read as quickly using computers and natural speech as sighted participants. (Contains references.)…
