Behavior therapy Study Guide

📖 Core Concepts Behaviour Therapy – Psychotherapy that changes observable behaviour using learning principles (classical & operant conditioning). Learning Principles Classical (respondent) conditioning: neutral stimulus → paired with unconditioned stimulus → eventually elicits the same response. Operant conditioning: behaviour is increased by reinforcement (reward) or decreased by punishment. Functional Analysis (S‑O‑R‑C) – Breaks a problem down into Stimulus (trigger), Organism (internal state), Response (behaviour), Consequence (outcome). Empirical/Measurable Focus – Treatment success is judged by objective, quantifiable change (e.g., baseline → post‑treatment scores). Third‑Generation (Third‑Wave) Therapies – Combine classic conditioning with functional and contextual analysis of language and cognition (e.g., ACT, DBT, BA). --- 📌 Must Remember Reinforcement vs. Punishment Positive reinforcement: add pleasant → ↑ behaviour. Negative reinforcement: remove aversive → ↑ behaviour. Positive punishment: add aversive → ↓ behaviour. Negative punishment (response cost): remove pleasant → ↓ behaviour. Key Techniques Systematic Desensitisation = hierarchy + relaxation → replace fear with relaxation. Exposure & Response Prevention (ERP) = confront stimulus + block avoidance. Token Economy = tokens → exchange for rewards; response cost removes token. Shaping = reinforce successive approximations toward target behaviour. Third‑Gen Hallmarks – functional analysis, contextualism, relational framing, acceptance‑change balance. Behavioural Activation (BA) – schedule of rewarding activities → treats depression. --- 🔄 Key Processes Functional Analysis (S‑O‑R‑C) Identify Stimulus (environmental trigger). Note Organism variables (thoughts, emotions, physiology). Record Response (observable behaviour). Observe Consequence (reinforcement/punishment). Systematic Desensitisation Teach relaxation skill. Construct fear hierarchy (least → most anxiety‑provoking). Pair each step with relaxation until anxiety drops. Token Economy Implementation Define target behaviours & token rules. Deliver token immediately after desired behaviour. Allow exchange for pre‑specified rewards. Apply response cost for undesired behaviour. Shaping Set final behaviour goal. Break into small steps. Reinforce each successive approximation. Fade reinforcement as full behaviour emerges. --- 🔍 Key Comparisons Classical Conditioning vs. Operant Conditioning Classical: involuntary response to paired stimulus. Operant: voluntary behaviour modified by its consequences. Positive Reinforcement vs. Negative Reinforcement + Reinforcement = add pleasant → ↑. – Reinforcement = remove unpleasant → ↑. Punishment vs. Response Cost Punishment: add aversive (positive) or remove pleasant (negative). Response Cost: specific form of negative punishment using token removal. Systematic Desensitisation vs. Exposure & Response Prevention Desensitisation = gradual exposure with relaxation. ERP = full exposure without avoidance/ safety behaviours. --- ⚠️ Common Misunderstandings “Punishment eliminates behaviour forever.” – Punishment may suppress but often fails to teach an alternative; risk of side‑effects. “Relaxation alone cures anxiety.” – Effective when combined with exposure or systematic desensitisation. “All CBT is the same as behaviour therapy.” – CBT adds explicit cognitive restructuring; pure behaviour therapy focuses on observable behaviour and environmental contingencies. “Token economies are only for children.” – Effective in adult settings (e.g., substance‑abuse programs) when contingencies are clear. --- 🧠 Mental Models / Intuition “Behaviour = Function of Environment + Consequence.” Think of behaviour as a lever: the environment pushes (stimulus), the consequence pulls (reinforcement/punishment). “The Chain of Learning.” Classical conditioning builds associations; operant conditioning builds contingencies. Both are needed for complex behaviour change. “Hierarchy = Staircase to Fearlessness.” Each rung (step) is a manageable exposure that, once mastered, lifts the whole staircase. --- 🚩 Exceptions & Edge Cases Extinction Burst – Temporary increase in the undesired behaviour when reinforcement stops; expect and plan for it. Stimulus Generalization – A learned response may spread to similar stimuli; may need additional discrimination training. Punishment May Produce Aggression – Especially with aversive stimuli; consider alternative reinforcement strategies. Virtual Reality Exposure – Works well for phobias with strong visual cues; less evidence for purely interoceptive fears (e.g., panic attacks). --- 📍 When to Use Which Use Systematic Desensitisation when the client can learn relaxation and the fear hierarchy is well‑defined. Choose ERP for OCD or compulsive behaviours where avoidance is the primary problem. Apply Token Economy in settings with clear, observable target behaviours (e.g., substance‑abuse, classroom). Select Shaping for complex or new skills (e.g., social skills, adaptive coping). Opt for ACT/DBT when contextual/acceptance issues dominate (e.g., chronic pain, borderline personality). Use Virtual Reality Exposure when in‑vivo exposure is impractical or unsafe (e.g., height, flying). --- 👀 Patterns to Recognize “Anxiety = High Arousal + Avoidance.” Look for safety behaviours → target with exposure/ERP. “Depression = Low Reinforcement Rate.” Identify reduced activity → intervene with behavioural activation. “Substance Use = Immediate Positive Reinforcement + Delayed Negative Consequence.” Apply contingency management to shift reinforcement. “Token Gains → Rapid Behaviour Increase, Token Loss → Immediate Decrease.” Monitor token flow for early signs of relapse. --- 🗂️ Exam Traps “Punishment = Best way to stop a behaviour.” Distractor – often less effective than reinforcement‑based alternatives. “Systematic desensitisation works without relaxation training.” Wrong – relaxation is a core component. “All third‑generation therapies are identical to CBT.” Mislead – third‑gen adds functional/contextual analysis and acceptance strategies. “Response cost is the same as positive punishment.” Incorrect – response cost removes a positive stimulus (negative punishment), while positive punishment adds an aversive. “Virtual reality exposure is only useful for phobias.” Over‑generalisation – also applied to PTSD, pain, and other anxiety‑related conditions. ---
