Behaviouralism • View person as a biological entity, similar to any other mammal • Personality is shaped in an effort to adapt to environmental circumstances • Shaping is predictable and stable • Environment “causes” personality
Behaviouralism • Human behaviour is learned • Learning occurs through patterns of reinforcement • Reinforcements are predictable patterns of reward and punishment • Over time, patterns become difficult to extinguish (or “unlearn”)
Conditioning Pavlov: Classical conditioning • Pairing of a stimulus and a response • Repeated exposure to stimulus provokes predictable responses • Basis for “learning” in animals and in humans (e.g. toilet training) • Behaviours that are classically conditioned
Conditioning Skinner - Operant Conditioning Premise: Organisms (including humans) are continually in the process of operating within an environment, and are seeking to adapt to it
Operant Conditioning Behaviour: any response to an external stimuli, including an emotion, thought, or action Reinforcing Stimulus: increases the operant (the behaviour occurring immediately prior to stimulus)
Operant Conditioning Principle 1: A behaviour followed by a reinforcing stimulus results in an increased probability of that behaviour occurring in the future Principle 2: A behaviour followed by an aversive stimulus results in decreased probability of that behaviour occurring in the future
Operant Conditioning Principle 3 (Extinction): A behaviour no longer followed by stimulus results in decreased probability of behaviour occurring in the future
Application of Behaviouralism:Behaviour Modification Therapy Goal: To extinguish undesirable behaviour and replace with desirable behaviour Method: Use positive reinforcement techniques
Behaviour Modification Therapy Examples: - lifestyle modifications - smoking cessation - medication adherence
Behaviour Modification Therapy A Antecedent B Behaviour C Consequent
Summary • Identify target behaviour • Describe environmental conditions • Map out antecedents that predict behaviour • Map out consequents that positively reinforce behaviour • Develop substitute positive reinforcers • Implement environmental changes
1. Identify Target Behaviour • Compilation of PBI (Problematic Behaviour Inventory) • Identify and name key problem (e.g. “smoking” vs. “anxiety” (causing smoking)) • Triangulation of data: why is a behaviour a problem, and for whom?
2. Environmental Conditions • Social and cultural determinants of behaviour • Naming of triggers (people, events) • Role of triggers • Narrative techniques to elicit information
3. Mapping Antecedents • 5 W’s and H • Who/what triggers behaviour? • Where/when does triggering occur? • Why does triggering occur? • How does it occur?
4. Mapping Consequents • What rules govern positive or negative reinforcement of the behaviour in question? • What rewards/punishments are linked to the behaviour?
5. Substitute Reinforcers • What reinforcers are already in place? • What new ones can be introduced? • Avoid punishment (ie. negative reinforcement of negative behaviour) • Focus on positive reinforcement of positive behaviour • Caution re: coercive exchange
Strengths/Limitations of Behaviouralism Strengths: - effective, efficient for children - a “non-psychological” theory Limitations: - limited efficacy in complex situations - can be frustrating, time consuming - requires commitment and energy
As a pharmacist... • Help patient identify “patterns” • Help patient identify “reinforcers” • Don’t rely on education alone • Focus on positive reinforcement of positive behaviours • Praise and criticism by themselves have limited value; need other reinforcers
