Module 3: Theories and Models of Human Behaviour

This module provides participants with a professional understanding of major theories and models used to explain human behaviour. Rather than viewing behaviour through a single theoretical perspective, participants learn how different frameworks offer different explanations of why individuals behave as they do. The module introduces systems theory, psychodynamic perspectives, behaviourism, social learning theory, cognitive approaches, exchange perspectives and reasoned action approaches. Participants explore how systems theory emphasises the interaction between individuals, organisations and environments, while behavioural theories focus on learning, reinforcement and consequences. Social learning approaches highlight observation and modelling, while cognitive and reasoned action perspectives examine how beliefs, attitudes, intentions and perceived control contribute to behavioural decisions. The practical emphasis of this module is on selecting the most appropriate theoretical framework for a particular behavioural issue. Participants learn that effective practitioners should not force every problem into the same model. Instead, they should consider the nature of the behaviour, the context, available evidence and the purpose of the intervention before deciding which theoretical approach provides the strongest explanation.
