The Stroop effect is psychology's classic measure gauging the selectivity of attention to individual attributes of complex stimuli. The emotional Stroop effect gauges the influence on behavior of threat and emotional stimuli. The former taps central/executive processes abstracted from particular stimulus contexts, whereas the latter taps automatic…

Sensory or input factors can influence the strength of interference in the classic Stroop color-word task. Specifically, in a single-trial computerized version of the Stroop task, when color-word pairs were incongruent, opponent color pairs (e.g., the word BLUE in yellow) showed reduced Stroop interference compared with nonopponent color pairs…

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…

Background: Williams syndrome (WS) and Down syndrome (DS) are two neurodevelopmental genetically based disorders which exhibit mental retardation with a unique cognitive profile. Naming in individuals with WS and DS has been investigated in several studies, with results indicating that the performance of children with WS and DS is at a similar…

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…
