In contrast to exemplar and decision-bound categorization models, the memory and contrast models described here do not assume that long-term representations of stimulus magnitudes are available. Instead, stimuli are assumed to be categorized using only their differences from a few recent stimuli. To test this alternative, the authors examined…

The rhythm created by spacing a series of brief tones in a regular pattern can be disguised by interleaving identical distractors at irregular intervals. The disguised rhythm can be unmasked if the distractors are allocated to a separate stream from the rhythm by integration with temporally overlapping captors. Listeners identified which of 2…

Groups of Grade 3 children were tested on measures of word-level literacy and undertook tasks that required the ability to associate sounds with letter sequences and that involved visual, auditory and phonological-processing skills. These groups came from different language backgrounds in which the language of instruction was Arabic, Chinese,…

The current study examined whether 11-month-old and 12-month-old French infants were able to recognize familiar words in a situation yielding no extra-linguistic cues, before they made identified attempts at producing such words. A head-turn preference paradigm was used to compare infants' interest for familiar words against rare words. Lists of…

Paper presented at the International Seminar on Experimental Research in Music Education (University of Reading, Reading, England, July 9-16, 1968).

Two groups of English speakers received either auditory or articulatory instruction in learning to produce exotic sounds. Performance on production and discrimination tests indicated a striking superiority for the subjects who received systematic training in the production of exotic sounds as opposed to those subjects who received only…

The Vicens-Reddy System is unique in the sense that it approaches the problem of speech recognition as a whole, rather than treating particular aspects of the problems as in previous attempts. For example, where earlier systems treated only segmentation of speech into phoneme groups, or detected phonemes in a given context, the Vicens-Reddy System…

An experienced person, in such tasks as sonar detection and recognition, has a considerable superiority over a machine recognition system in auditory pattern recognition. However, people require extensive exposure to auditory patterns before achieving a high level of performance. In an attempt to discover a method of training people to recognize…

This brief report summarizes a study to identify primary bound conditions of sound level selection as a first step in collecting base-line data for evaluating selective listening performance in infants with known or suspected hearing loss. Ten normal 9 to 22 month old infants in their home cribs played with an automated operant "toy" that allowed…

The auditory perception skills of 32 learning disabled (LD) and 32 non LD culturally different elementary pupils were compared. Results of the Wepman Auditory Discrimination Test and three subtests of the Illinois Test of Psycholinguistic Abilities indicated consistent differences between the two groups on all four measures of auditory perception…

An experiment is reported in which 25 listeners were presented with pairs of stimuli of equal duration, but differing in fundamental frequency, and were asked to decide which of the two stimuli was longer. (Author/RM)

Groups of 7 1/2-month-old infants heard 1 of 8 episodes consisting of no, slight, moderate, or large discrepancy between a habituated standard and a transformed auditory stimulus. Patterns of cardiac deceleration supported the hypothesis that attentiveness is an inverted-U function of the degree of discrepancy between stimulus event and schema.…

Discrimination scores among 556 listeners from 14 to 98-years-old with flat sensorineural hearing losses (742 ears) were analyzed in terms of degree of hearing impairment and subject age. (Author/IM)

Compared with 36 children (6 to 8-years-old) were pitch discrimination ability and ability to deal with relational language. (Author/IM)

Results indicated that significantly more time is needed to perceive tempo increase than tempo decrease, uneven rhythm then even rhythm, and melody alone than melody with accompaniment. Furthermore, significant interaction effects involving beat locations of tempo change suggest that differential groupings may be a factor in tempo discrimination.…
