This study investigated the physiological responses to affective visual and auditory stimuli with eye-blink rate (EBR) as the physiological indicator and examined the relationship between this response and subjective anxiety-level ratings by means of Zuckerman and Lubin's Multiple Affect Adjective Check-list (MACCL).

The purpose of this study was to examine the impact of visual and auditory presentational features on young children's selection and memory for verbally presented content. Assessed as a function of action and sound were preschool children's preferential selection and recall of words presented in a computer microworld. A computer microworld…

An experiment was designed to demonstrate that infants as young as 3 months of age would show face/voice coordination in matched and mismatched conditions if exposure trials were extended to 1 minute in duration. A total of 16 infants participated in each of four experimental conditions. Conditions were (1) mother present with mother's voice…

This synthesis of the research on direct manipulation interfaces explores the nature of directness in computer interfaces and demonstrates that the concept of directness is complex, including two gulfs--for execution and evaluation--and two kinds of mappings--semantic mappings and referential distance. Examination of the complexities of the…

TWENTY-EIGHT SS (SUBJECTS) WERE PRESENTED WITH COMPUTER-GENERATED AGRAMMATICAL STATEMENTS, AND ASKED TO CARRY OUT TWO TASKS ON EACH OF TWO EXPERIMENTAL DAYS. TASK 1 WAS A FORCED-CHOICE EXPERIMENT IN WHICH 50 PAIRS OF STATEMENTS WERE PRESENTED AURALLY TO EACH S, WHO HAD TO SELECT THAT MEMBER OF THE PAIR WHICH HE FELT WAS THE BEST APPROXIMATION TO A…

This study attempts to evaluate procedures for studying hemispheric differences in newborn human infants and to determine what acoustic characteristics of speech sounds will trigger a left hemisphere (LH) repsonse. Within 48 hours of birth, 14 neonates were individually administered five aural stimuli which comprised two speech syllables, two…

The ability to resist distraction is an important requirement for air traffic controllers. The study examined the relationship between performance on the Stroop color-word interference test (a suggested measure of distraction susceptibility) and impairment under auditory distraction on a task requiring the subject to generate random sequences of…

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 study determined whether eight undergraduate normal listeners, presented with filtered speech, would produce consonant confusions similar to those previously reported for the hearing-impaired listener. (Author/SBH)

Seven children aged 7 to 9 years were auditorily presented five-digit numbers for retention intervals of 0 to 10 seconds. Pupil size was recorded during stimulus presentation, retention interval, and recall of items. (Author/SB)

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.…

This study tested the assimilation of an auditory-visual stimulus configuration in 32 infants aged 15 to 16 weeks. The infants' discrimination of matched and mismatched auditory-visual stimuli indicated that infants by 4 months of age are capable of constructing bimodal schemata. (JMB)
