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 purpose of this study was to (1) compare the semantic relationships among common nouns obtained via two different measurement procedures and (2) determine if the use of these relationships to classify the various words results in differential degrees of learning when the stimuli are cast in terms of the paired-associate learning paradigm.…

THIS STUDY FOCUSED ON THE GENERAL PROBLEM OF HOW THE TOTAL EFFECT OF A MULTIDIMENSIONAL STIMULUS IS COMPOUNDED FROM THE SIMPLE EFFECT OF ITS SEPARATE COMPONENTS IN THE CONTEXT OF STIMULUS GENERALIZATION. FROM A THEORETICAL LEVEL, THE PROBLEM WAS STUDIED IN TERMS OF THE GEOMETRY OF MINKOWSKI. AN EXPERIMENT WAS CARRIED OUT WITH 20 SUBJECTS WHO WERE…

THE EFFECTS OF SELECTIVE MANIPULATION OF PICTORIAL CONTENT UPON PAIRED ASSOCIATE LEARNING WERE TESTED AND EVALUATED. STIMULUS MATERIAL WAS VARIED BY AUGMENTING CONTOUR CUES AND DIMINISHING IRRELEVANT CUES. FIFTH-GRADE STUDENTS WERE ASSIGNED TO NINE DIFFERENT TREATMENTS, INVOLVING STIMULUS SLIDES THAT VARIED IN TREATMENT OF CONTOUR AND CONTEXTUAL…

The modern history of sports medicine is chronicled in a discussion of the first writings in English on sports medicine. What may have been the first writing in English is a section on first aid in the ENCYCLOPEDIA OF SPORT, published in England in 1898. It describes injuries commonly sustained in angling, boxing, cricket, cycling, football,…

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,…

The purpose of the present experiment was to explore what it is that people remember about complex pictures. The experiment investigated several types of information which people might remember about two kinds of pictures, those which represent real-world scenes and those which represent collections of objects. (Author/RK)

Students in grades 4, 6, and 8 were required to indicate whether or not a stimulus word belonged in either of two semantic categories that were held in memory. Results indicated that even for the youngest children semantically similar categories required less search time than dissimilar categories. (GO)

The role of reversibility in children's comprehension and memory for sequences of pictures was investigated for children in preschool, kindergarten, and first and second grades. Bidirectionality in the ability to remember and infer antecedents and consequences was assessed. (JMB)

The study assessed task performance of 25 hyperactive and 22 normal children (six to ten years old) with and without within-task color, holding task complexity constant. (Author)

The article discusses the use of visual motivation (for instance, the classroom bulletin board) in classrooms of orthopedically handicapped, learning disabled, and emotionally disturbed children. (PHR)

Accurate interpretation of visual images involves the learning of methods for representing three-dimensional reality on a two-dimensional surface. There are many instances where a given culture exercises its iconic expression. Discussion and comparison of cultural differences is presented and illustrated. (Author/JEG)

Discusses a writing exercise in which students are asked to describe a painting and analyze their response to it. (TJ)

Examines the latency and the accuracy of adult's and children's saccades under optimal warning and no-warning conditions. Subjects were nine adults (mean age =23.7) and nine elementary school students (mean age =8.5). (Author/MP)
