An Interactive Test of Color and Contour Perception by Artists and Non-Artists

The author explores Richard Latto's proposition that art com-municates effectively because art-ists manipulate basic features of form that the human perceptual system has evolved to detect. She offers an empirical test of the correlated proposition-that view-ers of art use these same fea-tures to assess art. The author presents the results of an experi-ment in which both artists and non-artists were asked to discern and draw shapes in patterns de-fined by iterating dots. She finds that both groups used color in the case of positive shape and form edge in the case of negative space, thereby confirming that both makers and viewers of art fo-cus on the same kinds of features to recognize and assess form.

Sense Modality

When a user integrates a sensory substitution device into her life, the process involves perceptual learning, that is, ‘relatively long-lasting changes to an organism’s perceptual system that improve its ability to respond to its environment’. In this chapter, I explore ways in which the extensive literature on perceptual learning can be applied to help improve sensory substitution devices. I then use these findings to answer a philosophical question. Much of the philosophical debate surrounding sensory substitution devices concerns what happens after perceptual learning occurs. In particular, should the resultant perceptual experience be classified in the substituted modality (as vision), in the substituting modality (as auditory or tactile), or in a new sense modality? I propose a novel empirical test to help resolve this philosophical debate.

The aim of the study was to explore the basic features of self-schema in persons with schizophrenia. Thirty two schizophrenic patients and 32 normal controls were asked to select personality trait words from a check-list that described themselves, themselves as they were five years ago, and what most people are like. Compared with the control group, participants from the experimental group chose significantly more adjectives that were common to descriptions of self and others, and significantly less that were common to self and past-self descriptions. These results suggest that schizophrenic patients experience their personality as changing over time much more than do healthy subjects. Moreover, their self-representation seems to be less differentiated from others-representation and less clearly defined than in normal subjects.
