Used multidimensional research design to assess the salient dimensions that supervisors rely on in their perceptions of supervisor roles and to test models. Three dimensions emerged based on supervisor roles: supervision environment, supervision function, and characteristics of supervisor roles. The results partially supported a two-dimensional…

In contrast with controls and newborn presented with static models, only newborn presented with dynamic models reproduced the models' actions at significant levels. Infants in the static condition fixated the experimenter longer than those in the dynamic one. Results are discussed in terms of neurophysiological findings concerning the control of…

So far as we know, the brain is unlike any other structure in the universe, and perhaps only the vast complexity of the universe itself presents conceptual problems equally impenetrable. While much that is useful has been learned, the working of the brain remains elusive. (MT)

A set of studies examined infant categorization of the orientation of visual stimuli by establishing a categorization function for the orientation continuum; attempted to determine a perceptual boundary between "oblique" and "vertical"; and explored the relationship between discrimination abilities and the perceptual boundary.…

Tested and confirmed, in three experiments, the hypothesis that children's interpretation of pictorial conventions and of the expression "look like" may increase their tendency toward intellectual realism. That is, a tendency to respond to requests for perceptual reports by indicating what is known about an object or array, rather than…

Two experiments examined changes in the search of infants aged six, seven, and eight months. Experiment 1 found that the majority of infants displayed transitional search before intentional search. Experiment 2 showed that the infants' awareness of a hidden object develops gradually. (Author/RH)

Disfunctions are drawn between visual perception and visual function, and four optometrists respond with further analysis of the visual perception-visual function controversy and its implications for children with learning problems. (CL)

Methods and optics of perceiving color in a black-and-white grating are described. A sample grating which produces the effect is included. (JN)

Two experiments were conducted to demonstrate that human infants 3 months of age perceive color in a normal, trichromatic manner. Results from these studies of the neutral zone and hue discrimination evidence trichromatic vision in infancy and are discussed in the context of their clinical, social, and intellectual implications. (Author/SB)

The Agent-action-Objective (AaO) axiom and the theory of rotational dynamics constitute the frame of reference for the study of the metaphor as instrument for the direct perception of events. The major hypothesis of this frame of reference refers to the event structure embedded in the ground of a metaphor. Since the ground is implicit in the…

The author proposes that the small businessman is an appropriate clientele for Extension and provides a model for effecting the change in Extensions's role. (AG)
