Visual search has been studied extensively, yet little is known about how its constituent processes affect subsequent emotional evaluation of searched-for and searched-through items. In 3 experiments, the authors asked observers to locate a colored pattern or tinted face in an array of other patterns or faces. Shortly thereafter, either the target…

Two experiments examined whether postsample signals of reinforcer probability or magnitude affected the accuracy of delayed matching to sample in pigeons. On each trial, red or green choice responses that matched red or green stimuli seen shortly before a variable retention interval were reinforced with wheat access. In Experiment 1, the…

An effective way to teach the concept of image is to give students a model of human vision which incorporates a simple mechanism of depth perception. In this study two almost identical versions of a curriculum in geometrical optics were created. One used a mechanistic, interpretive eye model, and in the other the eye was modeled as a passive,…

Goals and challenges pertaining to infant sensory and perceptual development are discussed. It is suggested that the inability of researchers to think and talk wisely about "partial accomplishments" in development creates a barrier in developmental research. Conceptual schemes are needed to accommodate these partial accomplishments. Three major…

A discussion of the visual aspect of second-language reading processes proposes a theoretical model of reading and reports on research into the kinds of questions second-language students ask in class. The model of reading outlined is based on the operations of the human eye. Just as the operations of the lens (focus) change the picture at the…

The accuracy of non-art college students' longterm retention of structural information presented in Leonardo da Vinci's "Mona Lisa" was tested. Seventeen female undergraduates viewed reproductions of the painting and copies that closely resembled structural attributes of the original. Only 3 of the 17 subjects reported having viewed a reproduction…

Images express meaning through particular configurations of visual concepts. A distinguishing feature of discipline based art education is the use of visual imagery to transmit meaning to students. Discipline based art education incorporates concepts and skills from aesthetics, art criticism, art history, and art production and presents a unique…

A series of easy activities for parents or caregivers to use in guiding the developmental progress of children at the infant, toddler, and preschool levels. (Author)

Following a review of the literature on responses of autistic persons to environmental stimulation, three experiments are detailed which examine the relationship between modality preference and rate of acquisition of a discrimination task. First, seven autistic children's preference for colored lights and/or simple tones was assessed in a sensory…

Two experiments were designed to study the relative importance of various letter segments in letter recognition. One experiment was conducted with 24 subjects and the English alphabet, the other with 15 subjects and the Hebrew alphabet. In each experiment a letter was presented for identification, but was preceded by a brief presentation of either…

Thirty-two Hawaiian children in grades two, four, and seven participated in a study designed to test an ethnographic observation that rural Hawaiian children are highly sensitive to movement and location in their visual environment, and also to test the effect on the children of using Pidgin versus Standard English (S.E.). The children were…

First and third grade children's ability to coordinate reading and listening was studied using a "mismatch detection" task. A total of 15 first grade children and 15 third grade children of average to below average reading ability read printed texts while listening to recordings of the same texts, in which extraneous spoken words were…

THE ABILITY OF SECOND GRADERS TO PRODUCE TACHISTOSCOPICALLY PRESENTED LETTER SEQUENCES AND DISCRIMINATE AND VOCALLY REPRODUCE AUDITORILY PRESENTED WORDS WAS STUDIED IN THREE EXPERIMENTS. THE READING DISABILITY GROUP WAS FOUND TO BE SIGNIFICANTLY AND CONSISTENTLY INFERIOR TO THE CONTROL GROUP IN REPRODUCING THE VISUALLY PRESENTED LETTER SEQUENCES…

THIS WORKBOOK WAS DEVELOPED IN A CURRICULUM PROJECT, DESCRIBED IN VT 004 454 TO HELP JUNIOR HIGH SCHOOL STUDENTS LEARN BASIC PRINCIPLES AND CONCEPTS OF MECHANICS AND TECHNOLOGY BY MEANS OF A SERIES OF APTITUDE TRAINING EXERCISES. THE EXERCISES ARE SIMILAR TO APTITUDE TESTS EXCEPT THAT AN EXPLANATION OF THE UNDERLYING PRINCIPLE AND THE CORRECT…

THIS WORKBOOK WAS DEVELOPED IN A CURRICULUM PROJECT DESCRIBED IN VT 004 454, TO HELP YOUNG PEOPLE LEARN BASIC PRINCIPLES AND CONCEPTS OF MECHANICS AND TECHNOLOGY BY PROVIDING EXERCISES SIMILAR TO THOSE IN APTITUDE TESTS, EXPLANATIONS OF THE UNDERLYING PRINCIPLES, AND THE CORRECT ANSWERS. IT IS THE SECOND OF FOUR BOOKS WHICH PRESENT 30 EXERCISES…
