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.
