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

Case Study

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
