11.1 - The Behaviourist Perspective
The origins and core beliefs of behaviourism
Behaviourism, often referred to as 'learning theory', emerged in the early 20th century as a significant approach to understanding human and animal behaviour. It posits that nearly all behaviours are acquired through interaction with the environment, shaping individuals as products of their surroundings rather than innate traits.
Foundations of behaviourist thought
- Historical beginnings - Originating in America during the early 1900s, behaviourism gained prominence through John Watson's influential 1913 article titled "Psychology as the behaviourist views it", which laid the groundwork for this school of thought.
- Central belief - The primary assumption is that most behaviours are learned post-birth through environmental experiences, rejecting the idea of inherent or predetermined characteristics.
- Philosophical roots - Behaviourism is influenced by empiricism, the idea that knowledge is derived from sensory experiences with the environment, and the concept of "tabula rasa", meaning humans are born as blank slates ready to be shaped by external influences.
Key figures and influences in behaviourist theory
Behaviourism was developed and refined by several prominent psychologists who contributed foundational ideas and methodologies. Their work was also shaped by broader scientific and historical contexts that influenced the direction of psychological research.
Pioneers of behaviourism
- John Watson - Often considered the father of behaviourism, Watson championed the idea that psychology should focus on observable behaviours rather than internal mental states.
- Edward Thorndike - Contributed early ideas on learning through trial and error, laying the groundwork for later behaviourist theories.
- B.F. Skinner - Advanced behaviourism with his work on operant conditioning, focusing on how consequences shape behaviour.
Influences on behaviourist development
- Scientific emphasis - Drawing from the physical sciences, behaviourists prioritised objective and measurable methods of investigation, aiming to make psychology a more rigorous scientific discipline.
- Historical dominance - Behaviourism was the leading approach in experimental psychology until the late 1950s, when it began to face challenges from ethologists, who studied natural animal behaviours, and cognitive psychologists, who focused on mental processes.
Types of conditioning in behaviourist learning
Behaviourists proposed that learning occurs primarily through conditioning, a process where behaviours are associated with specific stimuli or consequences. Two main forms of conditioning were identified as central to this learning process.
Classical conditioning
- Key proponent - Ivan Pavlov, a Russian physiologist, developed this concept through experiments with dogs.
- Process - Involves learning through association, where a neutral stimulus becomes linked with an unconditioned stimulus to elicit a conditioned response.
Operant conditioning
- Key proponent - B.F. Skinner introduced this form of learning, focusing on the role of consequences in shaping behaviour.
- Process - Behaviours are influenced by rewards (positive reinforcement) or punishments (negative reinforcement or direct penalties).
Social learning theory as a modification of behaviourism
While traditional behaviourism focuses on direct environmental influences, social learning theory introduces a broader perspective by incorporating cognitive elements into the learning process.
Key aspects of social learning theory
- Key proponent - Albert Bandura developed this theory, suggesting that learning is not solely a result of direct experience but also occurs through observation.
- Core concept - Individuals can acquire behaviours by watching and imitating others, known as modelling. This process acknowledges the role of mental processes in learning.
- Distinction from strict behaviourism - Unlike pure behaviourist approaches that focus on stimulus-response mechanisms, social learning theory integrates cognitive factors, representing a shift from traditional views while still rooted in the idea of learned behaviour.
Implications of behaviourism for understanding behaviour
The principles of behaviourism carry significant consequences for how behaviour is interpreted and addressed, particularly in practical settings.
Practical applications of behaviourist ideas
- Learning as a basis for behaviour - Since behaviour is seen as learned from the environment after birth, it suggests that individuals are highly adaptable to their surroundings.
- Unlearning undesirable behaviours - If behaviours are acquired through learning, it follows that negative or antisocial behaviours can be modified or 'unlearned' through targeted interventions.
- Influence on interventions - Behaviourist principles underpin many modern approaches to changing behaviour.
