What This Document Is
This document is a study guide specifically created for Exam 4 in Colorado State University’s PSY 252: Mind, Brain, and Behavior course. It focuses on the unit covering disorders across the lifespan, and serves as a review of key concepts and potential exam questions. It is designed to help students prepare for an exam focused on psychological disorders and cognitive aging.
Why This Document Matters
This study guide is essential for students enrolled in PSY 252 who are preparing for their fourth exam. It consolidates important information regarding schizophrenia, obsessive-compulsive disorder, Alzheimer’s disease, and Korsakoff’s syndrome, as well as the typical characteristics of cognitive aging. Utilizing this guide can help students efficiently focus their studying and identify areas where they may need further review. It’s most valuable when used *in conjunction* with course lectures, readings, and previous study guides.
Common Limitations or Challenges
This study guide is a *review* tool, not a replacement for comprehensive learning. It highlights key points but does not provide in-depth explanations of complex topics. Students should not rely solely on this document to master the material; it’s intended to supplement, not substitute, other course resources. It also explicitly states to revisit Units 1-3, meaning core foundational knowledge is assumed.
What This Document Provides
This study guide includes:
* Key symptoms and distinctions between positive and negative symptoms of schizophrenia.
* Typical onset ages for schizophrenia in men and women, along with information on genetic and environmental factors.
* Biological factors (genetic mutations) and environmental factors (pregnancy complications, season of birth) linked to schizophrenia.
* Brain structures affected by schizophrenia (cerebral cortex, ventricles, corpus callosum, thalamus, basal ganglia) and how they differ from unaffected brains.
* An overview of dopamine receptor excess in schizophrenia.
* Symptoms and the interplay between obsessions and compulsions in obsessive-compulsive disorder.
* Brain differences associated with obsessive-compulsive disorder (orbitofrontal cortex, caudate nucleus).
* Therapies for obsessive-compulsive disorder (medications, behavioral therapy).
* Characteristics of normal cognitive aging.
* Information on Alzheimer’s disease, its impact on the brain, and affected areas (cortex, hippocampus, ventricles, basal ganglia).
* An explanation of Korsakoff’s syndrome and how it differs from Alzheimer’s disease.
* Protective factors for healthy cognitive aging (exercise, genetics, temperament).
This preview *does not* include detailed explanations of the biological mechanisms underlying these disorders, specific research studies, or practice exam questions. It is a high-level overview of the topics covered in the full study guide.
