Study Notes

Genes, Behaviour, and Environment

This module covers the science of behaviour, including human cognition, health-related behaviours, and health behaviour change.

Behaviour and Health

Behaviour affects health and is part of the "psycho" component of the biopsychosocial model.
Behavioural medicine is the study of factors that influence how we maintain our health, prevent illness, and manage illness.

The Behaviourists

Pavlov, Skinner, and Bandura are key figures in the study of behaviour.

Learning Theory

Classical conditioning: behaviours acquired through associative learning between two stimuli.
Operant conditioning: learning behaviour through reinforcement and punishment.
Social learning theory: behaviours acquired by observing significant others carrying them out.

Classical Conditioning

Unconditioned stimulus: an environmental stimulus that prompts an innate response (e.g., food, loud noise).
Unconditioned response: an innate response/reflex (e.g., salivation, escape).
Conditioned stimulus: a stimulus that is initially presented simultaneously with the unconditioned stimulus to subsequently provoke an innate response when presented alone.
Conditioned response: an innate response/reflex activated by a conditioned stimulus.

Operant Conditioning

Antecedents or stimulus: a stimulus that triggers a behaviour (e.g., rat placed in box with lever).
Behaviour: the action taken (e.g., rat presses lever).
Consequences of behaviour: the outcome of the behaviour (e.g., receives positive reinforcement of food).
Reinforcement: strengthens behaviour, punishment: weakens behaviour.

Attention: observing the model, retention: remembering the observed behaviour, reproduction: imitating the behaviour, motivation: having a reason to imitate the behaviour.
Vicarious reinforcement study (1965): children learn by observing others receiving reinforcement or punishment.

COM-B Model

A comprehensive theoretical framework of behaviour that takes into account capability, motivation, opportunity, and behaviour.
Capability: psychological capacity (knowledge, skills, and confidence) and physical capacity.
Motivation: voluntary (conscious rational decision making) and involuntary (habits, emotions, impulse).
Opportunity: factors outside the control of the individual (e.g., social environments).

Quick Quiz

Pavlov's bell acted as a conditioned stimulus.
A study on pregnant mothers receiving gift vouchers for attending smoking cessation services is an example of operant conditioning.
