These findings were consistent with the theories put forth that a diagnosis of schizophrenia is made by a high score on deviating from normal emotional indications, as well as the theories that schizophrenics tend to have cognitive deficits with regards to context processing, and not as many cognitive deficits with regards to spatial processing.
Schizophrenia is an illness that is characterized by a number of neurocognitive impairments, including impairments in attention, executive functioning, and verbal and non-verbal memory. (Gooding & Braun 261). Failure in logical reasoning is also a hallmark of schizophrenia (Tsanikos 1717), as is emotional disturbance (Yoon et al. 2008). Schizotypal personality disorder (SPD) is often associated with schizophrenia, and some theories state that schizophrenia and SPD share the same genetic liability, with environmental stressors being a leading cause of SPD turning into schizophrenia. (Olin et al. 93).
Research has shown that schizophrenics tend to perform poorly on tasks that involve sustained attention. (Rawlings & Goldberg 2001) (Hoff & Kremen 2003). This would affect the participants, as the spatial reasoning portion of the study was timed, therefore it would be predicted that the higher on the schizotypal scale the participant is, the lower he or she would score on the spatial reasoning scale.
Research has also established a positive correlation between schizophrenia and schizotypal personality disorder and emotional disturbance. (Yoon et al. 2008). Yoons study of participants who scored high on the Schizotypal Personality Questionnaire (SPQ) found a positive correlation for depression, anxiety and anger, and a negative correlation for mood clarity and mood repair. (Yoon et al. 2008). This is backed up by other research. For instance, Kohler (2003) has shown that schizophrenics have difficulty reading facial
