Proposed is a neuronal network capable of learning pattern discrimination. (Author)

A theory on the features of a visual scene and how these features are organized to provide a representational model of the visual scene is presented. (HB)

AN ATTEMPT WAS MADE TO DISCOVER PRINCIPLES LEADING TO A CHOICE OF ELEMENTS OR COMBINATION OF ELEMENTS IN GRAPHIC CONFIGURATIONS WHICH WOULD RESULT IN INCREASED EFFICIENCY IN LEARNING. EACH GRAPHIC CONFIGURATION WAS THOUGHT OF AS HAVING TWO ELEMENTS--A PRIMARY STIMULUS OBJECT AND A CONTEXT. TWO HYPOTHESES WERE TESTED THROUGH A LEARNING AND…

The latency at which objects could be identified by 126 subjects was compared through line drawings (edge-based) or color photography (surface depiction). The line drawing was identified about as quickly as the photograph; primal access to a mental representation of an object can be modeled from an edge-based description. (SLD)

Results indicate that infants are able to recognize a human face from a specific motion pattern even when the face lacks static facial features. (PCB)

Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

Investigated changes in non-nutritive sucking behavior of premature infants when light stimulation was presented. Results generally support past evidence that premature infants are capable of making orienting and discriminative responses to visual stimuli and chronological age effects were indicated. (DP)
