What is the difference between a theoretical model and a computer model in psychology?

Theoretical models are diagrammatic representations (like flowcharts) of mental stages, whereas computer models are actual software simulations designed to mimic human cognitive functions.

How does the cognitive approach differ from the behaviorist approach regarding internal processes?

The cognitive approach argues that internal mental processes should be studied through inference, while behaviorists ignore them because they cannot be directly observed.

When should a researcher use 'inference' instead of direct observation?

Inference is used when the subject of study (like memory or attention) is internal and 'private,' making it impossible to measure directly through physical observation.

What is the danger of 'machine reductionism' in cognitive models?

It oversimplifies human behavior by ignoring the influence of emotions and social factors, which can lead to models that do not accurately reflect real-life human complexity.

Why might a cognitive experiment lack 'ecological validity'?

Cognitive experiments often use artificial tasks (like memorizing random word lists) in controlled lab settings, which may not represent how people think in everyday life.

What is a common mistake when interpreting the 'computer analogy'?

The mistake is assuming the mind and computer are identical; in reality, the mind is organic, emotional, and prone to errors that computers do not typically make.

Define 'Internal Mental Processes' (IMP).

IMP refers to the private operations of the mind, such as perception, attention, and memory, that occur between a stimulus and a behavioral response.

What is 'Soft Determinism'?

It is the view that human behavior is influenced by internal and external factors, but individuals still possess the conscious ability to make choices and exercise free will.

What does the 'Information Processing Approach' suggest?

It suggests that information flows through the mind in a systematic sequence of stages: input, transformation (processing), and output.

Why are theoretical models often compared to flowcharts?

Because they represent the 'flow' of information through the mind, showing how data is transferred from one mental 'store' or process to another.

Assumptions & Theoretical Models in Cognitive Psychology

Summary

The cognitive approach focuses on how internal mental processes, such as memory and perception, influence behavior. Because these processes are not directly observable, psychologists use theoretical and computer models to make scientific inferences about how the mind functions as an information processor.

1. Definition & Core Concepts

Internal Mental Processes (IMP): These are the private operations of the mind, such as attention, perception, and thinking, that mediate between a stimulus and a response.
Inference: Since IMP cannot be seen, researchers must use inference, which involves drawing logical conclusions about mental events based on observable behaviors and experimental data.
Cognitive Approach: A perspective in psychology that views the human mind as an active processor of information, similar to a computer system.

2. Underlying Principles: The Information Processing Approach

Linear Flow: Information is viewed as flowing through the cognitive system in a sequence of stages, typically involving input, transformation/processing, and output.
The Computer Analogy: This principle suggests that the mind functions like a computer. The brain is the 'hardware,' while the mental processes are the 'software' that encodes, stores, and retrieves data.
Encoding and Storage: Just as a computer converts data into binary code, the mind encodes environmental stimuli into mental representations that can be stored in memory for later use.

3. Methods & Techniques: Theoretical and Computer Models

Theoretical Models: These are abstract, diagrammatic representations (like flowcharts) used to visualize the sequence of mental stages, such as how a memory moves from short-term to long-term storage.
Computer Models: These involve creating software programs or computational simulations that mimic human cognitive functions to test if a theory can produce the same results as human behavior.
Scientific Rigor: Both types of models allow psychologists to create testable hypotheses, ensuring that the study of the mind remains objective and empirical.
