The effects of telegraphic prose upon the comprehension of written and auditorily presented messages were tested. Two separate experiments were conducted. Subjects for the first experiment were 60 undergraduates enrolled in a remedial reading program; subjects for experiment 2 were 100 undergraduates enrolled in an introductory educational…

An earlier study indicated that a subject's performance on simple mental tasks, such as tracing soluble and unsoluble geometric designs and proofreading, was not affected by background noise regardless of its intensity, unpredictability, or uncontrollability. But, since background noise did have a significant effect on postnoise task performance,…

Cortical evoked responses were recorded from 66 nonretarded and 66 Down's syndrome Ss in order to compare the inhibitory processes of the two groups. (Author/PHR)

The study was designed to determine the extent to which auditory and visual stimuli influence certain sound productions of 250 children (preschool-third grade). (Author)

Eighty-six adults serially recalled lists of visually presented consonant letters similar in auditory or visual features or dissimilar on both feature sets. There were significantly more errors at every auditory list position than at the corresponding visual and neutral list positions, which did not themselves differ. Positive correlation exists…

Three experiments investigated the relationship in speech perception between the mechanisms that determine the source of speech sounds and those that analyze their actual acoustic contents and extract from them the acoustic cues to a sound's phonetic description. (Author/RK)

Focused and divided auditory attention were studied in 7- and 10-year-old children. (BD)

The study involving 10 normal hearing young adults was designed to determine to what extent onset times of overlapping spondaic words were controlled in the development of the Staggered Spondaic Word Test (List EC), a measure which is used to detect perceptual processing problems associated with central auditory dysfunction. (Author/SBH)

To test the tendency of subjects to perceptually organize discrete temporal patterns with regard to runs of identical stimulus events, spatiotemporal patterns of white noise were presented for reproduction. It is suggested that changes in runs of auditory patterns are perceptually analogous to changes in contours of visual patterns. (Editor/RK)

A standard operant procedure, Visual Reinforcement Audiometry, was modified to enhance 16 infants' attention to impending auditory signals. The modified technique achieved an average 5.5 dB improvement in threshold over the conventional technique. Correction for adult performance in similar tasks indicated a 3.3 dB attentional effect between…

Infants expressed more joy and looked longer at their mothers during a joy condition, and they showed more sadness, anger, and gaze aversion during a sadness condition. They engaged in more play behavior in the joy condition than in the sadness condition. Several significant relations between infants' gaze behavior, emotion expressions, and play…

Localization acuity was examined by determining the smallest sound shift off midline and along the horizontal axis that infants 6-18 months could reliably discriminate. As their age increased, infants demonstrated a finer partitioning of auditory space along the horizontal axis. (PCB)

Reports on three experiments that assessed the attentional responses of 4-month-old infants to frequency-modulated sweeps corresponding to the frequency range of adult-to-infant and adult-to-adult intonational patterns. (HOD)

Crossmodal transfer of stimulus control procedures was used to establish reliable responding to an auditory cue in three severely multiply handicapped students who had previously failed to demonstrate reliable responses to stimuli presented in the auditory mode. As a result, all three students were able to participate in formal audiometric…
