They were recruited through a newspaper ad and had no histories of Axis I psychiatric disorders.
The subjects were shown images on a computer screen for 13, 26, 52, or 104 ms, sometimes upright and sometimes inverted, and were asked to indicate, by pressing one of two keys on a keyboard, whether the image of a face or a tree was located on the left side or on the right side of each drawing.
Results
Schizophrenia patients exhibited significantly less accuracy when they tried to detect upright and inverted faces than normal controls did. Stimulus durations made no difference as the deficit existed across all durations.
Unlike the detection of faces, tree detection was not significantly different for the two groups. A reduced stimulus inversion effect in schizophrenia was shown primarily in faces but not in tree detection. The only interaction shown to be significant was between group and stimulus orientations (upright or inverted). Other interactions were not significant. Tree detection was more accurate in normal controls than in patients, but this finding was independent of stimulus orientation. Antipsychotic drugs that patients were taking did not appear to be correlated with their accuracy in face detection.
Conclusion
The first stage of facial information processing appears to be impaired in schizophrenia. This would be the first and most basic perception in the brain's facial information processing system. The researchers argue that face recognition is "categorically different from recognition of other visual objects" and that a deficit in recognizing a face as a face in schizophrenia patients indicates a problem or impairment in the FFA part of the brain. They argue this because the problem is with detecting faces and not with detecting other visual objects. The researchers state, "The results of this study suggest that this is the case" (Chen et al., 2007, p. 5). For schizophrenics the face inversion effect was significantly greater than for tree inversion. The researchers argue this also...
Schizophrenia patient development of social skills and coping skills in the support group; how support group can help them within group session. Schizophrenia is observed in more than a couple of million adult Americans, both men and women. It is serious, chronic mental disorder in which the social dispensation as well as day-to-day activities are affected negatively. The main challenge that the patient then faces is that of ability to
Much of advice to parents of schizophrenics tended to be judgmental, before the environmental and genetic factors of the illness were known: Theories blaming schizophrenogenic or emotionally withdrawn mothers are now almost totally discredited. What current research attempts to suggest is that "family and environmental stressors -- encompassing very subtle interactions common to many families -- work only in tandem with biological determinants to produce psychosis [and schizophrenia]" (McFarlane 2007).
Schizophrenia Ron Howard's 2001 film biography of the life of John Nash, A Beautiful Mind, delves into the world of a man suffering from schizophrenia. However, the film treats the disease delicately, without offering too many stereotypes or classifications of mental illness. Rather, the audience is aware that behind Nash's genius is a disturbed, albeit "beautiful" mind. Russell Crowe plays Nash, a brilliant mathematician and professor. His doctoral thesis work is
Schizophrenia What is Schizophrenia? Schizophrenia is a chronic disorder of the brain that affects the way a person sees the world, and even how they think, and behave towards other people. Schizophrenic persons find it difficult to function normally, and often have serious challenges relating with others, managing emotions, thinking clearly, making conversations, and distinguishing between what is real and what is imagined (Helpguide, 2014; NIMH, 2014). This blurred perception of reality
Schizophrenia Symptoms of schizophrenia Schizophrenia is perhaps the most harsh and cruel mental disorder because it gives the sufferers views and insights of reality that are extremely uncommon and psychotic. People suffering from schizophrenia tend to hear unusual voices from within and also feel afraid, mystified, nervous and apprehensive on a consistent basis (Taken from; Janssen-Cilag http://www.psychiatry24x7.com/index.jhtml?product=schizophrenia). Onset and course Many people believe that people suffering from Schizophrenia actually have "split personalities," however; contemporary
Empirical studies, MRI scans, and other medical interventions can be used to test some of these theories. However, the exact causes of schizophrenia are likely to remain unknown until the connections between social and biological factors can be isolated. For this reason, schizophrenia is often seen as the key to understanding human nature, the human brain, and the link between nature and nurture in psychological functioning. II.
