Analyzes a method of detecting changes in a particular frequency band by evaluating the overall shape or profile of the auditory signal spectrum. Claims that profile analysis is different from intensity discrimination, and applies the new method to detecting noise sinusoid and to results obtained when signal frequency is uncertain.

This study investigated the perceived harmonic relationships between the chords that belong to three closely related musical keys. Many aspects of the results have direct correlates in music theory and may help to uncover basic psychological principles that govern the organization of pitch relationships underlying both musical composition and…

Children 6- to 7- and 9- to 10-years-old listened to pairs of words presented dichotically to the left and right ear either simultaneously or in immediate succession. Results indicated that pragmatic, serial relations dominate younger children's semantic organization, whereas logical, hierarchical relations dominate older children's semantic…

Reports the results of a study that investigated patterns of judgmental discriminations and preferences with regard to tone quality versus intonation of accompanied flute and oboe duet performances of simple melodies among music and nonmusic graduate and undergraduate students. (AM)

This study demonstrates that non-human primates can categorize the direction of the pitch change of tones in a sequence. Two "Macaca fascicularis" were trained in a positive-reinforcement behavioral paradigm in which they listened to sequences of a variable number of different acoustic items. The training of discriminating pitch direction was…

Research has shown that performance on the "Assessment of Basic Learning Abilities" (ABLA) test correlates with language assessments for persons with developmental disabilities. This study investigated whether performance on ABLA Level 6, an auditory-visual discrimination, predicts performance on a receptive language task with persons with severe…

The study's purpose is to determine the efficacy of the Tomatis Method of auditory stimulation as a therapeutic intervention for Auditory Processing Disorders (APD). Forty-one subjects (18 females, 23 males; 4.3-19.8 years old) were evaluated for APD. Performance on standardized tests indicated weaknesses with auditory processing skills. Each…

Background: Children with phonological problems are a significant proportion of many therapists' caseloads. However, little is known about current clinical practice with these children or whether research on the effects of therapy have influenced this practice. Aims: To investigate the methods of assessment and remediation used by therapists…

Poses as a problem the rules presented in traditional grammars on the agreement of adjective and substantive in French, specifically in respect to speaking and hearing. Offers a new classification in three categories, and gives reasons therefor. (Text is in German.) (IFS/WGA)

Investigated the possibility that evidence of frequency discrimination might be found when the experimental procedures involved the conjugate reinforcement of nonnutritive sucking. (SDH)

Discrepancy between angl head turn and loudspeaker location was measured on infants in auditory-alone and auditory-visual trials. Age and loudspeaker location had no effect on performance in auditory-visual trials. However, in auditory-alone trials, there were significant age differences. (PCB)

Twelve hearing-impaired and eight normal-hearing adults listened to speech and music programs that were reproduced using five different frequency responses (one flat, the others combinations of reduced lower frequencies and/or increased higher frequencies). Most preferred was a flat response at lower frequencies and a 6dB/octave increase…

The effects of unilateral and bilateral ear occlusion on auditory discrimination in background noise was tested among 36 adults with auditory figure-ground disorders and normal auditory discrimination ability. Results indicated that unilateral occlusion effectively eliminated the figure-ground disorder in most subjects. (Author/DB)

Reports an investigation of the auditory discrimination ability of black and white listeners when listening to both black and white speakers. (TO)
