This paper describes three experiments which demonstrated the presence of binaural perception abilities (the ability to use both ears) in 4-month-old but not in 2-month-old infants. All of the experiments employed a visual fixation habituation-dishabituation paradigm in which infants were given a series of visual fixation trials while binaural…

Discussed are normal and abnormal mechanisms of learning observed in the learning disabled child and associated educational implications. (DB)

Electromyographic experiments were performed indicating that durational differences between vowels that precede voiced consonants and those that precede voiceless ones are due to a sustention of muscular activity in articulation, which occurs only with vowels preceding voiced consonants. (SC)

How information is represented in visual images was explored in five experiments where subjects judged whether or not various properties were appropriate for given animals. The results support a constructivist notion of imagery, and the idea that images may act as analogues to percepts. (Author/DEP)

The equivalency of speech intelligibility scores obtained with the 10 individual lists within each of the Central Institute for the Deaf (CID) and the Revised CID (R-CID) Sentence Lists was investigated with 60 normal-hearing subjects. (Author)

Four experiments (E1, E2, E3 and E4) investigated whether or not 5- to 7-month-old infants could detect auditory-visual relationships in audiovisual presentations of affective expressions, thereby perceiving the bimodally-presented expressions as unitary events. In E1, 16 infants were simultaneously shown two 2-minute films of a "happy"…

The magnitude of the dichotic right ear advantage was assessed in 48 normal and 48 learning disabled (LD) children (mean age 8.3 years). Ss were matched according to age, sex, and handedness. An analysis of results indicated a significant right ear advantage in both the normal and LD children, but revealed no developmental trend for either group.…

Three experiments examined the effects of selected factors of interval size, timbre, loudness, and length of the melodic pattern on children's ability to perceive, the motion of 2- and 3-pitch melodic patterns. Subjects for all experiments were 32 second- and 32 fifth-grade children. The task for each experiment consisted of identifying the motion…

PERCEPTION IS DEFINED AS THE MEANINGFUL RESPONSE TO THE VISUAL OR ORAL SIGNAL WHICH IS UNIVERSALLY REFERRED TO AS WORDS. PERCEPTION INCLUDES THE AROUSAL OF MEANING AND IS A CONSCIOUSNESS OR AN AWARENESS OF THE EXPERIENCES ELICITED BY THESE VISUAL OR ORAL SIGNALS. IMPROVING WORD PERCEPTION INVOLVES AT LEAST THE FOLLOWING THREE PROCESSES WHICH ARE…

A STUDY WAS CONDUCTED TO DETERMINE WHETHER AUDIOVISUAL PERCEPTUAL ABILITY CAN ACCOUNT FOR READING ACHIEVEMENT. SUBJECTS WERE 120 PUPILS SELECTED RANDOMLY FROM 38 SCHOOLS IN ILLINOIS. PUPILS WERE IN GRADES 2, 4, AND 6. MEASURES OF VISUAL PERCEPTION, AUDITORY PERCEPTION, VISUAL-AUDITORY SHIFTING PERCEPTION, INTELLIGENCE, SOCIOECONOMIC STATUS, AND…
