Auditory Attentional Deficit In Schizophrenia, Esther Ann Gimpel
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. …

The Effects Of Positive And Negative Reinforcement On A Learning Task In Hospitalized Patients, Gary Robert Lancaster
University of the Pacific Theses and Dissertations
A number of writers have suggested that in comparison to normals, schizophrenics are less responsive to positive records or reinforcers (e.g., Hunt & Cofor, 1944) and overly sensitive to punishment or social censure as compared to normals (Fromm-Reichman 1954). Garmezy & Rodnick (1957) have proposed that schizophrenics are highly sensitive to any censure or disapproval, arising from their interpersonal contacts. They further say that such intolerable levels of anxiety are aroused that schizophrenics are held to be much more strongly motivated than normals to reduce the anxiety by acting to avoid or escape the censorious aspects of the situation.
Kinesthetic Perception And Schizophrenia, Charles Robert Cherry
Kinesthetic Perception And Schizophrenia, Charles Robert Cherry
University of the Pacific Theses and Dissertations
It was the purpose of this study to compare normals with schizophrenic psychiatric patients as to their ability to reproduce movements perceived by kinesthetic stimulation. Kinesthetic perception, for the purpose of this study, was restricted to the reproduction of single arm-hand movements in a horizontal plane, away from the body. The magnitude of errors as a function of distance moved was defined as an indicator of kinesthetic perception.
