The effect of stimulus class on the problem-solving behavior of schizophrenics and normals.

"The ability of normal and schizophrenic Ss to deal with information involving human and nonhuman stimuli was compared. When Ss were matched on the basis of ability to utilize information about nonhuman stimuli, it was found that the problem-solving behavior of schizophrenics was significantly disrupted by the presence of human stimuli in the test situation. When the same populations were matched for ability to solve problems involving human stimuli, no significant difference was found in their capacity to deal with information involving nonhuman stimuli."
