1. Introduction to Psychology

  • Definition:
    Psychology is defined as the science of behavior and mental processes.
  • Key Concepts:
    • Behavior: Observable actions (e.g., yelling, smiling, blinking, sweating, talking, filling out questionnaires).
    • Mental Processes: Internal and subjective experiences inferred from behavior, such as sensations, perceptions, dreams, thoughts, beliefs, and feelings.

2. Research in Psychology

  • Basic Research:
    Pure science is aimed at increasing the overall scientific knowledge base.
  • Applied Research:
    Scientific studies are designed to solve practical, real-world problems.

3. Major Psychological Approaches

Humanistic Approach

  • Focus:
    Emphasizes personal choice and self-determination.
  • Key Idea:
    Individuals are guided by their physiological, emotional, or spiritual needs.

Behavioral Approach

  • Focus:
    Analyzes behavior through the lens of conditioning.
  • Key Idea:
    Explains human thought and behavior in terms of observable responses and the consequences they elicit.

Psychoanalysis Approach

  • Focus:
    Treatment and explanation based on the impact of past experiences.
  • Key Idea:
    Unconscious influences stemming from personal history can affect current mood, behavior, relationships, work, and self-esteem.

Evolutionary Approach

  • Focus:
    Looks at human thoughts and actions through the process of natural selection.
  • Key Idea:
    Psychological traits that are advantageous for survival are likely inherited across generations.

Cognitive Approach

  • Focus:
    Investigates how people interpret, process, and remember environmental information.
  • Key Idea:
    Mental “rules” or schemas shape the way we think and behave.

Biological (Neuroscience) Approach

  • Focus:
    Attributes behavior to biological processes.
  • Key Idea:
    Human cognition and reactions are influenced by genes, hormones, and neurotransmitters.

Social-Cultural Approach

  • Focus:
    Examines how cultural contexts influence thoughts and behaviors.
  • Key Idea:
    Family, friends, environments, and religious views play significant roles in shaping behavior and cognition.

4. The Biopsychosocial Approach

  • Integration:
    Combines elements from biological, psychological, and social-cultural perspectives to provide a more comprehensive understanding of behavior.
  • Example:
    An extroversion tendency can be explained by:
    • Biological factors: Inherited genes affecting neurotransmitter levels.
    • Behavioral conditioning: Rewards or punishments influencing social behavior.
    • Evolutionary pressures: The survival advantage of being socially outgoing.
    • Cognitive interpretation: How social cues are perceived.
    • Social-cultural influences: Norms regarding interpersonal distance and group behavior.
