Study Notes
Reaction Time (RT)
- Measures the time it takes to respond to a stimulus, indicating the duration of information processing in the nervous system.
Problem Size Effect
- Refers to the phenomenon where RT increases as the problem size or complexity increases.
Channel Capacity/Bandwidth Analogy
- Used to describe the limits of information processing, suggesting that the human brain has a limited capacity for processing information simultaneously.
Computer Analogy
- Suggests that human information processing can be compared to a computer's processing of information, implying that the human brain operates in a serial, sequential manner.
- Criticized for being an outdated approach, oversimplifying the complexities of human cognition.
Outdated Approach
- The "modularity" approach, which suggests that cognition equals the coordinated operation of active mental processes with a multi-component memory system.
Assumption of Reaction Time (RT) Measurement
- Assumes that RT is a direct reflection of the duration of internal processing.
Criticism of Computer Analogy
- Fails to account for the complexities and dynamic nature of human cognition, oversimplifying the human brain as a sequential processor.
Principles of Function in Neurology
- Localization, hierarchization, and integration are discussed as principles of function in relation to neurology.
Cognitive Science
- Involves the interdisciplinary study of mind and intelligence, encompassing psychology, computer science, philosophy, and neuroscience.
Difficulty of Strict Information Processing
- Emphasizes the challenge of accounting for the complexities of human cognition using a strict information processing approach.
Concept of Dissociation
- "A disruption in one component of memory but no impairment of another" represents the concept of dissociation.
Material Basis of the Mind
- "The mind has a material basis" refers to the need to delve into the neural basis of cognitive processing for a fuller understanding.
