Ratings of perceptual experience on a trial-by-trial basis are increasingly used in masked priming studies to assess prime awareness. It is argued that such subjective ratings more adequately capture the content of phenomenal consciousness compared to the standard objective psychophysical measures obtained in a session after the priming…

The development of the Visual-Perceptual Chemistry Specific (VPCS) assessment tool is based on items that align to eight visual-perceptual skills considered as needed by chemistry students. This tool includes a comprehensive range of visual operations and presents items within a chemistry context without requiring content knowledge to solve…

The ability of 3-month-old infants to discriminate novel components of a pre-familiarized stimulus was assessed using an operant paradigm. Subjects were 20 infants; adult judgments were taken from 15 college students. (Author/JH)

Describes two studies that demonstrate young children's perception of color materials differs from that of adults in two ways: (1) the stimulus dimensions of hue, chroma, and value appear to result in somewhat more separable perception for young children than for adults, and (2) the perceived similarities the color materials are not the same for…

Three experiments were performed using an aperture-viewing technique to assess the accuracy of shape perception when subjects were required to emit eye movements in order to pick up shape information, compared with the accuracy of shape perception when subjects were not required to emit eye movements. All three experiments explored whether the…

Reports replication and extension of Elkind and Weiss's study of perceptual exploration using 122 Israeli children. In general, results were upheld and reflected the influence of school experiences seen most specifically in the right-left directionality expected to result from learning to read Hebrew. (WY)

Research was designed to determine whether developmental differences in sensitivity to more peripherally presented material could be found under conditions in which overt eye movements during the presentation of task material were not possible. (Author)

To investigate the relationship between the location of the words being read and the location of the eyes in the text, three experiments were conducted using the Disappearing Text Technique with college students. This was done by occasionally removing the text during reading and having the reader report the last word that had been read.…

Certain asymmetries of perception in the right and left visual fields of American college students have been described as the effect of a reading habit which predisposes the subjects to scan or organize material in a left-to-right direction and thus to identify more accurately the items in the left field. The purpose of the present work was to…

This study was designed to provide evidence concerning hemispheric independence in the visual modality of children and adults. Words and letters were shown either singly or in pairs. Hemispheric independence occurred more frequently among children when letters, as opposed to words, were shown. Results are discussed in terms of developmental models…

Investigates age differences in selective attention in a coded visual search task where subjects were given different types of information about target location before trial onset. (Author/SS)
