Cognitive Approach to Understanding Human Behaviour

TL;DR

The cognitive approach focuses on how our internal mental processes like perception, memory, and thinking influence our behavior. It sees the mind as an information processor, similar to a computer, actively interpreting and organizing sensory input. Understanding these processes helps explain why we act, feel, and make decisions the way we do.

1. The Mental Model

The cognitive approach views the human mind as a complex system that takes in information, processes it, and then produces an output (behavior). It's all about what goes on inside your head – how you perceive the world, store memories, solve problems, and make decisions.

2. The Core Material

The cognitive approach suggests that our behavior isn't just a reaction to external stimuli, but rather a result of our internal mental representations and processes. This means how you interpret a situation is more important than the situation itself.

Key Cognitive Processes:

• Perception: How we interpret sensory information from the world around us. This isn't just seeing or hearing; it's giving meaning to what we sense.
• Memory: Our ability to encode, store, and retrieve information. This includes different types like short-term (working) memory and long-term memory.
• Thinking/Problem-Solving: The mental manipulation of information to reason, make decisions, and overcome obstacles.
• Language: Our system for communication, which is deeply intertwined with how we think and store information.
• Attention: The process of focusing our cognitive resources on certain stimuli while ignoring others.

Assumptions of the Cognitive Approach:

1. Mental processes can be scientifically studied: Even though you can't see thoughts, their effects on behavior can be measured and inferred.
2. The mind is like an information processor: This often uses the computer analogy, with input, processing, storage, and output.
3. Mental processes mediate (come between) stimulus and response: It's not just S -> R, but S -> Cognitive Processes -> R.

Schema Theory

A crucial concept in the cognitive approach is schema theory. Schemas are mental frameworks or blueprints that help us organize and interpret information. Think of them as mental shortcuts based on our past experiences and knowledge. They influence what we pay attention to, how we interpret new information, and what we remember.

For example, you have a "restaurant schema." When you go to a new restaurant, you already know to expect menus, waiters, food, and a bill because of this schema. This saves cognitive effort.

Here's how schemas work:

    A["New Information/Stimulus"] --> B{"Compare to Existing Schemas?"}
    B -- "Yes, Matches" --> C["Assimilate: Integrate into existing schema"]
    B -- "No, Doesn't Match" --> D{"Is a new schema needed?"}
    D -- "Yes" --> E["Accommodate: Create new schema OR Modify existing one"]
    D -- "No" --> F["Ignore/Misinterpret (Schema Incongruence)"]
    C --> G["Influence Perception & Memory"]
    E --> G
    F --> G

Research Methods:

Cognitive psychologists use a variety of research methods, including:

• Laboratory experiments: To control variables and establish cause-effect relationships (e.g., memory recall tasks, reaction time experiments).
• Case studies: In-depth studies of individuals with specific cognitive impairments (e.g., amnesia patients) to understand normal cognitive functioning.
• Brain imaging techniques: fMRI, PET scans to observe brain activity during cognitive tasks, linking brain areas to specific functions.

3. Worked Example

Let's consider how the cognitive approach explains why you might forget where you put your keys.

1. Input: You put your keys down.
2. Attention: If you were distracted (e.g., on your phone, thinking about something else) when you put them down, your attention wasn't fully encoding the action. This means the information didn't effectively get into your memory system.
3. Encoding: Because of the lack of attention, the 'where I put my keys' information wasn't properly encoded into your long-term memory. It might have only stayed in your short-term (working) memory for a brief moment.
4. Retrieval: Later, when you need the keys, you try to retrieve the memory. However, because the initial encoding was poor, or perhaps interference from other thoughts, you can't access the information.
5. Behavior: You search frantically, demonstrating a behavior caused by a breakdown in a cognitive process (memory retrieval).

This example highlights that the problem isn't a lack of effort now, but a failure in the initial cognitive steps (attention and encoding) that happened earlier.

4. Key Takeaways

• The cognitive approach emphasizes how internal mental processes shape our behavior.
• It views the mind as an information processor, using an input-process-output model.
• Key processes include perception, memory, thinking, language, and attention.
• Schema theory explains how mental frameworks influence our interpretation of new information and memories.
• Research methods often involve controlled experiments and brain imaging to study mental processes.
• Dysfunctions in cognitive processes (like attention or memory encoding) can lead to observable behavioral issues.
• It provides a scientific way to study complex internal mental states that aren't directly observable.

Common Mistakes to Avoid:
- Don't confuse the cognitive approach with the biological approach; while both involve the brain, the cognitive approach focuses on mental processes rather than purely biological structures or chemicals.
- Don't assume cognitive processes are always conscious; many happen automatically.
- Avoid oversimplifying the computer analogy; the human mind is far more complex and capable of self-awareness and emotion.
- Don't forget to link specific cognitive concepts (like schemas or attention) back to observable behaviors in your explanations.

5. Now Try It

Think about a time you experienced a cognitive bias, like confirmation bias (seeking out information that confirms your existing beliefs) or the availability heuristic (making judgments based on how easily examples come to mind). Describe the situation and explain how specific cognitive processes (e.g., schemas, attention, memory retrieval) contributed to that bias. What would success look like? You'd be able to clearly outline the situation, identify the bias, and link it directly to at least two specific cognitive processes, explaining how each contributed to your biased thinking or decision.
