Pioneering research has shown that infants are capable of perceptual discrimination and has provided some indication of the nature of the discrimination; that is, what stimuli are differentiable. Studies have demonstrated that significant effects exist, in stimulus-pair comparisons, for age of infant, speed of movement of stimulus during…

This study examined behavioral correlates of the rapid central nervous system changes occurring in the first 4 months of life. It was hypothesized that during the early months of infancy, visual preference would occur as a function of quantitative dimensions of the stimuli (size) which could be mediated at a subcortical level. It was further…

Two important processes in the acquisition of visually presented information are the ability to maintain discrete perceptual events as separate in time and the ability to abstract information from brief exposures. Five phenomena were measured which appear to reflect these abilities. Critical Flicker Frequency (CFF) is the intermittency rate at…

Describes ways for developing visual imagery in the early childhood education program, preparing children for discrimination learning and reading instruction. (RL)

Purpose of this study was to test the hypothesis that training the student to note the distinctive features of a stimulus during perceptual learning facilities the hook-up phase in a paired-associate task. (Author)

An infant's unique style and temperament is thought to develop during a given small time segment as a consequence of the initiatives taken by caretaker or infant; usually an interaction of the two. (WY)

Earlier research with the lexical decision task led to the hypothesis that semantic context facilitates the encoding of words related to the context. Six experiments which employed different tasks (e.g., making a lexical decision) and different experimental paradigms (e.g., tachistoscopic exposures with masking stimuli) further investigated this…

Eight experiments investigated the effects of visual, spatial, auditory, and executive interference on the symbolic comparison of animal size and ferocity, semantic goodness of words, and numbers. Dynamic visual noise (DVN) and the reading of visually presented stimulus items were shown to selectively interfere with response times on the animal…

The current study examined the reinforcing effects of choosing among alternatives in a four-part evaluation. In the first study, initial-link responses in a concurrent-chains arrangement resulted in access to terminal links in which the completion of an academic task resulted in (a) the choice of a reinforcer (choice), (b) the delivery of an…

Reported are three series of experiments analyzing the development of the visual function of infants. The first experimental series was aimed at the investigation of infants' reaction to moving objects. The second experimental series dealt with the analysis of the development of binocular vision in infants. The goal of the third series was to…

In order to enhance the understanding of visual literacy, one of its constituents, visual learning (VL), is examined in terms of underlying assumptions, hypothesized behaviors, and implications of both assumptions and behaviors. Assumptions are: (1) VL encompasses all changes in behavior arising from the individual's responses to visual…

This experimental study was conducted in an attempt to determine how children--four, seven, and 11 years old--perceive implied motion cues in combination with a variety of objects. Ninety children, 30 in each age group, were shown 24 pictures. There were three kinds of objects, each with an inherent active and static dimension. Each of these six…

This study presented 24 third graders drawn from suburban elementary schools with high frequency, low discriminability words in four conditions. Subjects were randomly assigned to the four tasks individually. It was hypothesized that poor and normal readers would differ in their ability to read high frequency, low discriminability words presented…

The reflection-impulsivity (R-I) dimension of individual variation incognitive processes is discussed. A literature review focuses on studies that have supported the validity of the R-I dimension as a concept, and studies providing evidence of a direct relationship between the R-I dimension and visual scanningstrategies. This study compares the…

Visual fixation on one of two blank targets was reinforced with either visual or auditory stimuli in one of 3 intensity sequences: (1) low, medium, high; (2) medium, high, low; and (3) high, low, medium. An analysis of variance of learning scores for the 48 14-week-old infants resulted in a significant interaction of intensity and order and in a…
