Basic and Applied Psychology, Learning Strategies, and Research Methods

Basic and Applied Psychology and Careers

• Basic Research: Research primarily intended to increase knowledge.
• Applied Research: Research intended to solve practical problems.
• Clinical Psychology: Assessment and treatment of mental, emotional, and behavioral disorders.
• Counseling Psychology: Helps people cope with life challenges and transitions.
• Developmental Psychology: Studies change across the lifespan.
• Social Psychology: Studies how people think about, influence, and relate to one another.
• Cognitive Psychology: Studies thinking, memory, language, perception, and problem-solving.
• Industrial-Organizational Psychology: Applies psychological science to workplaces and organizations.
• Educational Psychology: Studies learning and educational processes.
• Sports Psychology: Studies psychological factors related to athletic performance and participation.
• Psychiatry: Psychiatrists are physicians ($MD$/$DO$) who specialize in mental health and can prescribe medication; they are distinct from psychologists.

Psychological Strategies for Effective Studying

• Testing Effect / Retrieval Practice: Actively retrieving information from memory strengthens learning. Self-quizzing is more useful than only rereading.
• Spacing Effect: Learning is improved when study sessions are distributed over time rather than packed into one cramming session.
• Active Processing: Explain ideas in your own words, make examples, teach the concept, and practice recalling it without looking.

Core Distinctions and Conceptual Differences

• Theory vs. Hypothesis:

  • Theory: Explanation.
  • Hypothesis: Testable prediction.

• Correlation vs. Causation:

  • Correlation: Shows a relationship; it does not prove cause.
  • Causation: Proves cause and effect.

• Positive vs. Negative Correlation:

  • Positive Correlation: Same direction.
  • Negative Correlation: Opposite directions.

• Random Sample vs. Random Assignment:

  • Random Sample: Dictates who enters the study.
  • Random Assignment: Dictates which condition participants enter.

• Independent Variable vs. Dependent Variable:

  • Independent Variable ($IV$): Manipulated variable.
  • Dependent Variable ($DV$): Measured variable.

• Experimental Group vs. Control Group:

  • Experimental Group: Treatment condition.
  • Control Group: Comparison condition.

• Structuralism vs. Functionalism:

  • Structuralism: Structure/components of conscious experience.
  • Functionalism: Purpose/function of consciousness.

• Basic Research vs. Applied Research:

  • Basic Research: Build knowledge.
  • Applied Research: Solve practical problems.

Practice Quiz and Application Questions

• Question 1: A researcher finds that students who sleep more tend to have higher GPAs. What can be concluded?

  • Answer: The variables are correlated; the finding alone does not prove that sleep causes higher $GPA$.

• Question 2: A researcher changes the amount of sleep participants receive and measures memory. What is the $IV$ and $DV$?

  • Answer:
  • Independent Variable ($IV$): Amount of sleep participants receive (manipulated variable).
  • Dependent Variable ($DV$): Memory (measured variable).
