The Effects Of Blindness On Tactile And Auditory Perception In Rats, James Malcolm Claiborn
The Effects Of Blindness On Tactile And Auditory Perception In Rats, James Malcolm Claiborn
University of the Pacific Theses and Dissertations
Folklore has long held that blind people gain, relative to normal people, in their sensitivity to other sensory modalities. Although supported only by equivocal evidence, this position probably first appeared in mythology in early Greek literature. Oedipus Rex was attributed greater awareness of people’s nature after this blindness. It is still a prevalent myth in contemporary American culture, to the extent that it appears in “Little Orphan Annie.” Experimental attempts at verification of this point began several years ago, but it remains a controversial issue. Literature on the topic can be divided up into several content areas: the relevance of …
The Relationship Between Linguistic Behavior And Diagnostic Classifications In The Language Processing Systems Of Bilingual Schizophrenics, Lee Sue Curry
University of the Pacific Theses and Dissertations
Both of these theoretical positions - the linguistics and the behavioristic - are introduced here as parallel structures within which a study of language can proceed. As this study is developed, each strand is evident to some extent, with a synthesis of the two evolving in a psycholinguistic model which characterizes actual language use. This model, with the addiction of a bilingual dimension, is then discussed in light of schizophrenic language deviations.

Auditory Attentional Deficit In Schizophrenia, Esther Ann Gimpel
University of the Pacific Theses and Dissertations
Differences in auditory detection performance between schizophrenics and normals were examined in terms of the attentional processes involved. Each of 40 ~s (20 schizophrenics categorized along the dimensions of paranoia, premorbidity, and acuteness; and 20 hospital technical staff) were presented with 30 50-trial blocks of a tone detection task using 6 auditory ensembles consisting of 2 tones apiece separated by varying . ,. frequency bands. Tones were masked by white noise and presented in a free-running trial manner. The commonly found decrement in detection performance with normal subjects as the tones in the ensembles become more widely separated was replicated. …
