Study Notes on Theoretical Perspectives in Psychology

Theoretical Perspectives in Psychology

Overview of Theoretical Perspectives

  • Definition: Theoretical perspectives provide an orientation to understand the causes of human behavior and the treatment of abnormality.
  • Purpose: Influences the ways clinicians and researchers organize and interpret their observations about behavior.

Major Theoretical Perspectives

Humanistic Perspective
  • Core Principles:
    • Centered on individual potential and the importance of self-actualization.
    • Emphasizes empathy and unconditional positive regard in therapeutic settings.
  • Key Concepts:
    • Person-Centered Therapy (Carl Rogers): Focus on congruence between self-image and experience.
    • Self-Actualization (Abraham Maslow): Achieving one’s maximum potential.
    • Maslow's Hierarchy of Needs:
    • Levels of Needs:
      • Physiological: Food, drink
      • Safety: Security, psychological safety
      • Love/Belonging: Affection, acceptance
      • Esteem: Competence, approval, recognition
      • Self-Actualization: Achievement of full potential
Psychodynamic Perspective
  • Influence of Sigmund Freud (1856-1939):
    • Focuses on the influence of the unconscious mind on behavior.
  • Freud's Model of Personality Structure:
    • Id: Instinctive part of personality, operates on the pleasure principle.
    • Ego: Balanced and rational part of personality, operates on the reality principle.
    • Superego: Moral component, which guides the ego's pursuit of the id's desires.
  • Consciousness Levels:
    • Conscious: Awareness of the external world.
    • Preconscious: Material just beneath the surface of awareness.
    • Unconscious: Inaccessible material well below the surface of awareness.
  • Defense Mechanisms:
    • Tactics to keep unacceptable thoughts out of conscious awareness.
    • Examples of Defense Mechanisms:
      • Repression: Unconsciously pushing anxiety-producing information out of awareness.
      • Denial: Refusal to acknowledge a painful aspect of reality.
      • Projection: Attributing unacceptable traits to others.
      • Regression: Reverting to child-like behaviors to cope with distress.
      • Sublimation: Transforming unacceptable impulses into socially acceptable activities.
    • High Adaptive Defenses: Healthy responses to stress such as humor and self-assertion.
Behavioral Perspective
  • Core Concepts:
    • Behavior as a response to environmental stimuli (Pavlov, Skinner).
    • Classical Conditioning (Pavlov):
    • Process of associating a neutral stimulus (CS) with an unconditioned stimulus (UCS) that elicits an involuntary response.
    • Example: Pavlov's dogs—salivation response conditioned to a bell.
    • Operant Conditioning (Skinner):
    • Behavior modification through reinforcement and punishment.
    • Reinforcement:
      • Positive: Strengthens behavior by presenting a favorable outcome.
      • Negative: Strengthens behavior by removing an unfavorable outcome.
    • Punishment:
      • Positive: Weakens behavior by presenting an unfavorable outcome.
      • Negative: Weakens behavior by removing a favorable outcome.
    • Social Learning (Bandura):
    • Learning through observing others (Bobo doll experiments).
Cognitive Perspective
  • Core Belief: Dysfunctional thinking leads to maladaptive behavior.
    • Automatic Thoughts: Thoughts arising due to ingrained dysfunctional attitudes.
    • Cognitive Therapy Techniques: Focus on modifying dysfunctional thoughts and improving emotional well-being.
Sociocultural Perspective
  • Focus on: The influence of social interactions, family dynamics, and broader sociocultural contexts.
    • Family Perspective: Abnormality as a consequence of disturbances in family relations.
  • Historical Context: Impact of historical events on individual behaviors and attitudes.
Biological Perspective
  • Foundation: Psychological disorders viewed through abnormalities in biological functioning.
  • Components:
    • Nervous System: Role in emotions and behaviors.
    • Endocrine System: Hormones influencing behavior.
    • Genetic Influences:
    • Understanding the hereditary factors impacting psychological disorders.
    • Neurotransmitters:
    • Example: Serotonin associated with mood regulation and depression.
  • Treatment Options:
    • Medication: Psychotropic drugs specific to disorders (e.g., SSRIs for depression).
    • Psychosurgery: Surgical procedures on the brain to treat mental disorders.
    • Electroconvulsive Therapy (ECT): Treatment for severe depression.
    • Biofeedback: Training individuals to improve health by controlling physiological processes.
Developmental Psychopathology
  • Meta-Theory:
    • Considers behavior across developmental stages and contextual influences.
    • Emphasizes interactions of risk and protective factors over time.
  • Definitions:
    • Risk Factors: Characteristics that increase the likelihood of dysfunction.
    • Protective Factors: Attributes that decrease the likelihood of dysfunction.
Diathesis-Stress Model
  • Overview:
    • Proposes individuals have predispositions to disorders that may manifest under stress.
  • Example Scenario: Loss of a job as a stressor triggering latent issues.
Conclusion
  • Integration of Perspectives:
    • Most clinicians adopt a biopsychosocial approach, considering multiple factors in diagnosis and treatment planning.
