The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…

Cites research indicating that while students react more strongly to visual presentations, they recall more details when reading. Offers explanations for the differences. (MM)

Presents guidelines for orientation and mobility instructors and traffic engineers to assess the need for adaptive devices to make crosswalks at signalized intersections accessible to pedestrians with visual impairments. The discussions of audible and tactile pedestrian devices, along with case examples, distinguish when each device should be…

A study used semiotics to examine the graphic elements within corporate trademarks. The trademarks from 247 "Fortune" 500 corporations were placed into 86 different categories of graphic elements intended to connote 14 different qualities. Subjects, 40 college students and 61 business professionals, evaluated 9 sets of 12 trademarks in…

This paper examines human phonosensitivity (the process by which an organism receives acoustic stimuli and integrates them into its behavior patterns), which is divided into two distinct but inseparable systems: hearing, which controls the reception, transmission, and perception of acoustic stimuli, and listening, which controls the discrimination…

This study examined memory representation as it is exhibited in young children's formation of facial prototypes. In the first part of the study, researchers constructed images of faces using an Identikit that provided the features of hair, eyes, mouth, nose, and chin. Images were varied systematically. A series of these images, called exemplar…

The interaction between field dependence/independence and pictorial recognition memory was investigated using pictures in three different color modes: realistic color, non-realistic color, and black and white. The study was designed to further confirm the efficacy of applying signal detection analyses to color recognition memory data as a means of…

Examines the effect of exposure length of stimulus and the possible effects upon response. Results suggested that TAT pictures become less pleasant with continued exposures. (DEP)

Three experiments examined how people compare sentences about spatial location to pictures and images. (Editor)

Two experiments investigated the question of whether those attributes of stimuli effective in eliciting attention are also effective in motivating choice. (Editor)

The effectiveness of mental imagery instructions and picture presentation was evaluated in first and fourth grade children and in adults. Results indicated that the visual mnemonics reliably facilitated cued recall and recognition (but not free recall) in children but facilitated only free recall in adults. (Author/GO)

Nine institutionalized educable retarded children (mean age 12 years) and nine nonretarded children matched for chronological age were tested on a visual backward masking task. (Author)

To evaluate the hypothesis that memories are related to operative levels, children were shown pictures involving seriation, horizontality, and verticality and were asked to reproduce them 1 week and 5 months later. Although memories and operative levels did correlate, the relations were quantitatively weak and were undermined by serious…

The purpose of this paper is to describe a new piece of apparatus for generating stimuli for what Michotte (1963) called 'the perception of causality'. (Author)

Rat received conditioning based upon a food unconditioned stimulus and then received manipulations designed to reduce the value of that food. The effects of these manipulations were assessed during extinction tests of the conditioned stimuli. (Editor/RK)
