Cognitive approach: core idea

· Cognitive approach = explains observable behaviour by studying mental processes such as thinking, memory, attention, perception, language and decision-making.
· Emerged as a reaction to behaviourism, which focused on learning through stimulus–response links, reinforcement and punishment.
· Key assumption: the mind acts as an information processor, linking stimulus input to behavioural output.
· Cognitive psychologists use cognitive models to simplify and explain internal mental processes that cannot be observed directly.
· Exam focus: explain how a named cognitive process, model, theory or bias helps understand behaviour, then evaluate using research strengths/limitations.

This diagram shows the mind as a system that processes information in stages. It is useful for explaining the cognitive approach because it represents mental processing between stimulus input and behavioural output. Source

Behaviourism background: classical and operant conditioning

· Classical conditioning = learning by association between stimuli; explains how a neutral stimulus becomes linked to a response.
· Key terms: unconditioned stimulus (UCS), unconditioned response (UCR), conditioned stimulus (CS), conditioned response (CR).
· Operant conditioning = learning through consequences, where behaviour is shaped by reinforcement or punishment.
· Key terms: positive reinforcement, negative reinforcement, positive punishment, negative punishment.
· IB requirement: understand the process of both types of conditioning and apply them as explanations of behaviour.
· Strong exam link: use conditioning to explain how behaviour can be learned, maintained or changed.

Cognitive models

· Cognitive models = simplified representations of how a cognitive process works.
· Examples include computer model of information processing, memory models and models of language development.
· Strength: models help explain unobservable mental processes in a clear, testable way.
· Limitation: models can be reductionist because they may simplify complex, flexible human cognition.
· Exam use: describe the model, apply it to a specific cognitive process or behaviour, then evaluate how well it explains behaviour.

Schema theory

· Schema theory = people use mental frameworks to organize and interpret information.
· Schemas shape perception, memory, interpretation and expectations.
· Schemas help cognition by making processing efficient, especially when information is familiar.
· Schemas can also distort cognition by producing biases, memory errors or culturally influenced interpretations.
· Exam focus: explain the role of schema theory in understanding a cognitive process, especially memory, perception or decision-making.

This diagram represents schemas as organized mental structures. It helps students visualize how prior knowledge can guide interpretation, memory and expectations. Source

Dual processing theory

· Dual processing theory = thinking and decision-making involve both conscious and unconscious processing.
· Often summarized as fast, automatic processing and slow, controlled processing.
· Explains why people may make quick decisions using intuition, but also deliberate decisions using reasoning.
· Key exam link: dual processing helps explain decision-making, especially when automatic processing leads to cognitive biases.
· Evaluation idea: useful for explaining everyday decisions, but real thinking may involve interaction between both systems rather than a simple split.

Cognitive biases in decision-making

· Cognitive bias = a systematic pattern of thinking that can reduce objective judgement.
· Anchoring bias = relying too heavily on the first piece of information encountered when making a decision.
· Confirmation bias = seeking, noticing or interpreting information in ways that support existing beliefs.
· Biases may occur when people lack enough time, information or motivation to reason carefully.
· Exam focus: explain the role of anchoring bias or confirmation bias in decision-making, using a clear real-world example.
· Evaluation idea: biases show cognition is not always rational, but they may be efficient shortcuts in everyday life.

This image shows that cognitive biases are systematic and varied rather than random mistakes. For IB revision, use it as a broad overview, but focus exam answers only on the required biases such as anchoring and confirmation bias. Source

Cognitive load theory

· Cognitive load theory = learning and thinking are affected by limits in working memory capacity.
· High cognitive load can make learning harder because too much information must be processed at once.
· Helps explain why clear instructions, chunking and reduced distractions can improve learning.
· Exam link: useful for understanding human cognition, especially learning, attention and memory.
· Evaluation idea: strong applied value in education, but may not explain all learning because motivation, culture and prior knowledge also matter.

Applying the cognitive approach in IB contexts

· The cognitive approach can explain behaviour in learning and cognition, human development, health and well-being and human relationships.
· Cognitive models can help explain mental health disorders, cognitive processes and interpersonal behaviour.
· Schema theory can be applied to memory, perception, stereotypes, interpretation and learning.
· Dual processing theory and cognitive biases are especially useful for decision-making questions.
· Conditioning is useful when explaining how behaviours are learned or changed, especially through reinforcement and punishment.

Research and exam evaluation points

· Cognitive research often uses experiments because they allow control of variables and investigation of cause-and-effect.
· Strength: cognitive theories can generate testable predictions about behaviour.
· Strength: cognitive explanations often have strong real-world applications, especially in education, health and decision-making.
· Limitation: internal mental processes are difficult to observe directly, so researchers rely on indirect measurement.
· Limitation: some cognitive explanations may underemphasize biological, cultural and environmental influences.
· Strong evaluation phrase: “This shows the value of the cognitive approach, but behaviour is best explained through an interaction of biological, cognitive and sociocultural factors.”
