Three experiments studied the perception of tone sequences. Ratings of perceived structure and ease of recognition in transposition were both influenced by harmonic progression, the contour, and the excursion or repetition pattern within the sequence. Results are described in terms of the abstraction and analysis of levels of pitch relations.…

Presents activities for discovering and exploring sound in the environment and for creating a "musical" composition from everyday sounds. (SJL)

Methods of deriving more information from auditory discrimination tests of learning disabled children in order to better diagnose and provide programing are described. (PHR)

Two newly developed and three existing auditory speech discrimination tests were given to a group of 35 National Technical Institute for the Deaf (NTID) students representing the five NTID functional profiles (categories) of hearing discrimination ability. (Author/PHR)

To investigate students' ability to generalize auditory skills, precourse to postcourse measures were compared for an auditory training group (N=42) and a control group (N=7) on three auditory discimination measures: (1) the training sentences, (2) related but nontrained sentences (decoy sentences), and (3) a modified rhyme test. (Author/PHR)

In the study, 40 normal and 40 learning disabled children classified by age (five and six) and level of auditory discrimination (impaired and normal), were tested for language ability using an elicited imitation paradigm. (Author)

The author reviews research on the relationship between auditory discrimination and reading success, and contends that when auditory discrimination is defined broadly, a relationship exists between auditory skills and word calling. (For related material, see EJ 223 667.) (PHR)

This study examined the effects of the cochlear hearing loss of 12 adults on two measures of sequential processing that rely on spectro-temporal information: a gap-detection discrimination task and a melody recognition task. It was concluded that cochlear hearing loss deleteriously affects the processes underlying perceptual organization of…

Comparison of 48 cerebral palsied individuals (aged 10-18), either with impaired speech or normal speech, found speech-impaired subjects were able to discriminate phoneme contrasts adequately in a word judgment task but performed less well on a phoneme discrimination "same-different" task possibly resulting from a weak memory for novel…

Children with language learning problems (N=151) and normally learning children (N=143) were tested on fine-grained auditory discrimination tasks that required responding to small acoustic differences. Performance on the auditory tasks was highly correlated with group placement suggesting that fine-grained auditory discrimination makes a major…

The auditory temporal resolving power of young children was measured using an adaptive forced choice psycho-physical paradigm that was disguised as a video game. (PCB)

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…

Signal detection experiments with 21 college students suggest that streakiness is a property of auditory and visual discrimination in that correct and incorrect responses have a positive sequential dependency. Monte-Carlo simulations of observed data sequences suggest that streaky performance results from wavelike variations in perceptual and…

Frequency difference limens (DLFs) for pure tones were obtained over a wide range of frequencies and levels from 7 normal-hearing subjects and 16 ears of 12 listeners with sensorineural hearing losses. Results indicated that it is reasonable to use data from normal listeners' DLFs to evaluate DLFs from hearing-impaired listeners. (Author/JDD)

Sixty-four infants viewed side-by-side videotapes of toy trains (in four visual conditions) and listened to sounds at increasing or decreasing amplitude designed to match one of the videos. Results suggested that five-month olds were sensitive to auditory-visual distance relations and that change in size was an important visual depth cue. (MDM)
