Effects of ball color on horizontal perimetry detection

The subjects were 16 college students assessed as having normal, uncorrected visual abilities. Each subject responded to the appearance of each of five variously colored ball sections as they were introduced into the subjects' visual field. Analysis indicated that colors with luminance values greater than 70 CD/M2 (black, blue, green) were detected further in the horizontal peripheral plane than were colors possessing values less than 36 CD/M2 (red, purple).     

Size of human figure drawing and Goodenough-Harris scores of pediatric oncology patients: a pilot study

Human figure drawings of 12 pediatric oncology patients were significantly smaller in height, width, and area than were drawings of 12 school children and 12 pediatric general surgery patients paired for sex and age. The Goodenough-Harris scores of the cancer patients' drawings were also significantly lower than those of both school and general surgery groups. It is hypothesized that anxiety, lowered self-esteem, and the effects of chemotherapy contributed to these findings.     

Field dependence as a limiting factor in solving a complex learning problem

Subjects in a prior study of complex learning often experienced difficulty in mastering the task because of an apparent reluctance to release one perceptual field and reconstrue the task on a higher cognitive level. It was hypothesized that were this the correct explanation, the faster learners would be more field independent on a measure of field dependence, since independence has been defined in terms of ease in releasing one's attention from the immediate perceptual field. This hypothesis was tested with 22 undergraduate subjects for whom Group Embedded Figures Test scores were correlated with the number of trials to completion on the complex learning task. A moderate but significant correlation supported the hypothesis.
