Measures of visual and tactual recognition memory, tactual-visual transfer, and object permanence were obtained for preterm and full-term infants. Measures of tactual-visual transfer were correlated with later intelligence measures up to the age of five years. These correlations were independent of socioeconomic status, medical risk, and early…

Examined, over a 10-year span, continuity in individual differences in cross-modal transfer to visually recognized shapes that had previously been felt but not seen. Found that cross-modal performance showed a left-hand advantage at 11 years. Cross-age correlations were significant when tactual exploration at 11 years was done with the left hand.…

Identifies a function generator as an instrument that produces time-varying electrical signals of frequency, wavelength, and amplitude. Sending these signals to a speaker or a light-emitting diode can demonstrate how specific characteristics of auditory or visual stimuli relate to perceptual experiences. Provides specific instructions for using…

It has been 20 years since Bever's (1982) and Strauss and Stavy's (1982) books on U-shaped functions in human development were published. The three target articles in this issue describe several old and new U-shaped functions and new theoretical explanations for their existence. In this article, the authors will comment on two aspects of U-shaped…

Human interactions are multimodal in nature. From simple to complex forms of transferal of information, human beings draw on a multiplicity of communicative modes, such as intonation and gaze, to make sense of everyday experiences. Likewise, the learning process, either within traditional classrooms or Virtual Learning Environments, is shaped by…

A model is described to suggest how the visual system may keep track of perceived objects as their images move on the retina. (Author)

Presented in this report are the Illuminating Engineering Research Institute's fundamental scientific concepts in a new frame of realism while relating them to an up-to-date accounting of the search for new basic knowledge. In addition to being an annual accounting, it is also intended to provide orientation. Its presented in dramatic and…

This paper discusses recent studies of the adult visual evoked potential (VEP) which have indicated that specific components of the complex waveform obtained are related to the three basic color processes, and that these components interact in ways that seem to agree with opponent-colors phenomena. The components identified as being related to the…

This study evaluates the relationships that exist between three types of visual and perceptual-motor tasks (coincidence-anticipation, tracking with rotary pursuit, and a unique two-dimensional discrete motor task) and investigates the nature of learning demonstrated by the subjects on each of the three tasks. Thirty male students were given 20…

In this paper three experimental techniques are described for studying ambiguous characters and for investigating the relationship between physical attributes and functional attributes. (Author)

The multitrait-multimethod matrix technique was used to evaluate student responses to two tests of spatial orientation and visualization. The Eliot-Price tests met all criteria for convergent and discriminant validity. The Guilford-Zimmerman did not meet one of the criteria for discriminant validity. (Author/BJG)

Children of ages two and one-half, three, and three and one-half years were tested for their understanding of object hiding. Results indicated that children of this age can be both nonegocentric and skillful at estimating what other people do and do not see under various viewing conditions. (JMB)
