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…

The author cites work on visual perception which indicates that in order to study perception it is necessary to replace such classical geometrical notions as betweeness, straightness, perpendicularity, and parallelism with more general concepts. The term tolerance geometry is used for any geometry when primitive notions are obtained from the…

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)

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)

Inpatients (n=67) treated for alcohol and drug abuse were administered the MMPI (Minnesota Multiphasic Personality Inventory) and Luescher Color Test (LCT). Patients showed more preference for brown than did normal adults and also obtained higher (i.e., presumably more pathological) scores on Luescher's total score scale and compensation scale.…

Summarizes the efforts of teachers at all levels of education to prepare students with the basics of art education. Describes the art foundations program of the Maryland Institute College of Art, and concludes that perceptual drawing is the most basic of all art subjects. (JDH)

The study employed the use of field reversals--printing white and yellow foregrounds on a black background--to decrease the amount of light reflected from printed materials to the eye with 18 visually impaired children (9-14 years old). The findings indicated that neither reversals in contrast nor chromaticity differences were effective measures…

Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Some recent theoretical/experimental investigations of graphical perception are described, identifying certain elementary graphical-perception tasks that are performed in the visual decoding of quantitative information from graphs.…
