Cognitive Dysfunction Happens Early

One of the symptoms of schizophrenia is impaired cognition. Researchers decided to examine when these effects occured and what their course was over time in psychosis. The participants in the study were 247 individuals who were experiencing their first-episode of psychosis. The effects on cognitive dysfunction were followed up over a period of 3 years.

When compared to the controls at the beginning of the study it was apparent that they were doing much better on the cognitive tests than those experiencing psychosis. The cognitive tests looked at "measures of letter fluency, verbal memory, verbal learning, visual memory, and attention."

After 2 years those experiencing psychosis improved on most of the measures of the cognitive tests. These results exemplify that one's cognition is impaired early on when experiencing episodes of pscyhosis, but improves over time.

"They note that, after controlling for positive and negative psychotic symptoms, analysis showed that cognitive impairment accounted for a small, but significant, 4–6% of the variance in social functioning, as measured on the Quality of Life Scale. 'This may mean that, although related, poor social functioning may be independent of cognitive impairment,' explain Addington et al" (, 2005).

Cognitive dysfunction occurs early on and improves because psychotic episodes include dissociative elements in the event.

Historically most psychotic episodes improved with time.

Schizophrenia is a special case. The exposure that can cause sudden psychotic episodes is not known within the mental health industry.

Too-close side-by-side seating in classrooms is the same design problem that caused the discovery of Subliminal Distraction in the 1960's. The Cubicle solved that problem.

Hutterite Colonies have very low incidents of Schizophrenia. Researchers are trying to find out why. Hutterites stop schooling at 15. They have very small class sizes and some schools use the Montessori method.

This means Hutterite children have an almost zero exposure to Subliminal Distraction.

Research on this is being done at the University of Pittsburgh.

No one has recognized this problem and it appears to have dropped off the screen in psychology classes.

I thought that cubicles could have helped me, for I was disruptive in the presence of others .
