Schizophrenic Disorders:
Causes of Schizophrenia
Biological Factors - Genetics
• Schizophrenia tends to run in families.

predisposition (increased likelihood) to
develop schizophrenia.
•Genain Quadruplets
Genetics and Schizophrenia
Biological Factors – Brain Structure
• Brain structure of those with
schizophrenia is different than the
normal brain
• Those with schizophrenia have smaller
amounts of brain tissue and larger fluid
filled spaces.
• The thalamus is smaller in those with
schizophrenia.
Biological Factors – Brain Structure
Biological Factors – Brain Function
• The brain of those with schizophrenia
operates differently than the normal
brain.
• The frontal lobes show less activity.
• Those with schizophrenia have a larger
number of receptor sites for the
neurotransmitter dopamine.
Biological Factors – Prenatal Viruses
• A viral infection during the middle of
pregnancy may increase schizophrenia
risk.
Psychological Factors
• Two main areas:
– Stress
– Disturbed family
– It’s unclear whether these are causes
or consequences of schizophrenia.

Teacher Information
• Types of Files
– This presentation has been saved as a “basic” Powerpoint file. While
this file format placed a few limitations on the presentation, it insured the
file would be compatible with the many versions of Powerpoint teachers
use. To add functionality to the presentation, teachers may want to save
the file for their specific version of Powerpoint.
• Animation
– Once again, to insure compatibility with all versions of Powerpoint, none
of the slides are animated. To increase student interest, it is suggested
teachers animate the slides wherever possible.
• Adding slides to this presentation
– Teachers are encouraged to adapt this presentation to their personal
teaching style. To help keep a sense of continuity, blank slides which
can be copied and pasted to a specific location in the presentation follow
this “Teacher Information” section.
Teacher Information
• Domain Coding
– Just as the textbook is organized around the APA National Standards,
these Powerpoints are coded to those same standards. Included at the
top of almost every slide is a small stripe, color coded to the APA
National Standards.
• Scientific Inquiry Domain
• Biopsychology Domain
• Development and Learning Domain
• Social Context Domain
• Cognition Domain
• Individual Variation Domain
• Applications of Psychological Science Domain
• Key Terms and Definitions in Red
– To emphasize their importance, all key terms from the text and their
definitions are printed in red. To maintain consistency, the definitions on
the Powerpoint slides are identical to those in the textbook.
Teacher Information
• Hyperlink Slides - Immediately after the unit title slide, a page (usually
slide #4 or #5) can be found listing all of the module’s subsections. While in
slide show mode, clicking on any of these hyperlinks will take the user
directly to the beginning of that subsection. This allows teachers quick
access to each subsection.
• Continuity slides - Throughout this presentations there are slides,
usually of graphics or tables, that build on one another. These are included
for three purposes.
• By presenting information in small chunks, students will find it easier to process and
remember the concepts.
• By continually changing slides, students will stay interested in the presentation.
• To facilitate class discussion and critical thinking. Students should be encouraged to
think about “what might come next” in the series of slides.
