Orienting responses to visual and auditory stimuli were compared in 3 cohorts of preterm infants born between 1977 and 1987. The sample consisted of 128 infants born between 1977 and 1979, 129 infants born between 1980 and 1983, and 94 infants born between 1984 and 1987. The sample was divided into one group of 140 infants born between 25- and…

The purpose of the present experiments was to investigate the effects of backward masking on differential eyelid conditioning. (Author)

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…

In two experiments, subjects were given five successive short-term memory tests. The findings suggested spatial location as a potential encoding dimension of verbal material. (Editor/RK)

THIS STUDY DETERMINED WHETHER OR NOT DIFFERENTIAL BINAURAL STIMULATIONS CAN BE USED EFFECTIVELY TO IMPROVE PRONUNCIATION IN FOREIGN LANGUAGE TEACHING. THE OBJECTIVE WAS TO DETERMINE WHAT EFFECT HEARING SIMULTANEOUSLY THE TEACHER'S VOICE IN ONE EAR AND HIS OWN VOICE IN THE OTHER WOULD HAVE ON A STUDENT'S ABILITY TO COMPARE THE DIFFERENCES IN…

THIS PROPOSAL FOR A PRELIMINARY TAXONOMY OF THE PERCEPTUAL DOMAIN, ORGANIZED ON THE PRINCIPLE OF INTEGRATION, DREW ON GUILFORD'S THEORETICAL AND FACTOR-ANALYTICAL WORK, ON WITKIN'S FIGURE-GROUND STUDIES, AND ON THE "TAXONOMY OF EDUCATIONAL OBJECTIVES" MODELS. THE TAXONOMY CATEGORIES ARE SENSATION, FIGURE PERCEPTION, SYMBOL PERCEPTION, PERCEPTION…

THE SIXTH-GRADE STUDENTS OBTAINING THE 80 HIGHEST MEAN SCORES ON THE METROPOLITAN ACHIEVEMENT TEST FORM D WERE RANDOMLY ASSIGNED TO GROUPS OF EASY OR DIFFICULT TASKS WITHIN EACH OF FIVE DECIBEL LEVEL GROUPS. THE LEARNING TASKS WERE TAKEN FROM THE MEANINGFULNESS OF ALL POSSIBLE CVC TRIGRAMS (ARCHER, 1960). THE APPARATUS INCLUDED A TAPE RECORDING OF…

Under a background condition of either recorded radio chatter or no radio chatter, the individual performances of two flights of mid-phase instrument student pilots were measured during a simulated instrument cross-country mission in the T-38 ground trainer. Operational constraints prevented the exercise of optimal experimental controls, thereby…

This study investigated the classroom attention as well as performance on simple tasks of seriously disturbed, psychotic-type, verbally communicative children under conditions of reduced auditory input (using ear protectors) and under conditions of normal auditory input (using a placebo device). No significant difference was found in either task…

Sixteen 9-18 month normal/superior infants "played" in their home cribs with a two-channel operant "toy" which allowed free choice between alternate audio feedbacks. With more than 300,000 seconds of listening time in the response record, 12 babies successfully discriminated gross differences in auditory complexity, while 10 discriminated fine…

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…
