Study Notes

Introduction to Cognitive Psychology

Cognitive psychology is a branch of psychology that focuses on mental processes such as attention, memory, perception, language, problem-solving, and decision-making.
It attempts to understand how these processes work and how they affect behavior.
It utilizes various research methods, including experiments, and computational modeling.

Key Concepts in Cognitive Psychology

Attention: The ability to selectively focus on specific stimuli while ignoring others. This includes selective attention (focusing on one thing), sustained attention (maintaining focus over time), and divided attention (focusing on multiple tasks).
Memory: The ability to encode, store, and retrieve information. This encompasses sensory memory, short-term memory (working memory), and long-term memory, which in turn are further subdivided into different types like episodic, semantic, and procedural memory.
Perception: The process of organizing and interpreting sensory information to understand the world around us. This involves various processes like feature detection, pattern recognition, and object recognition.
Language: The complex system of communication using symbols and rules. Cognitive psychology studies language development, comprehension, and production.
Problem-solving: The process of finding solutions to challenges or dilemmas. This involves various strategies such as trial and error, algorithms, heuristics.
Decision-making: The process of selecting a choice among different options. This process can be influenced by cognitive biases, framing effects, and other psychological factors.

Models and Theories in Cognitive Psychology

Information-processing model: This model views the mind as a series of interconnected processing units, through which information is sequentially processed. Similar to a computer, with inputs, processing, and outputs (with feedback loops).
Schema theory: This theory proposes that individuals organize information into mental frameworks called schemas to understand and interact with the world. These schemas are developed through experience and influence how we perceive and interpret information.
Connectionism (Parallel Distributed Processing): A theory proposing that cognitive processes emerge from complex networks of interconnected nodes, where activation spreads across the network, creating parallel processing.

Research Methods in Cognitive Psychology

Experiments: Used to test hypotheses about cognitive processes. Often involve manipulation of independent variables to observe effects on dependent variables. This often includes control groups or conditions. Example is a memory task with a controlled group and experimental conditions.
Neuroimaging techniques (e.g., fMRI, EEG): Used to observe brain activity while participants engage in cognitive tasks. Provides insight into the neural correlates of cognitive processes. Example is identifying brain regions active during a memory task.
Behavioral tasks: Used to measure aspects of cognitive performance (e.g., reaction time, accuracy, error rate). Can be used to study various cognitive functions such as attention, memory recall and working memory.
Computational modeling: Used to develop computer simulations of cognitive processes. Helpful in understanding the underlying mechanisms of these functions, and how different variables interact.

Applications of Cognitive Psychology

Education: Understanding how individuals learn and how to facilitate optimal learning environments.
Healthcare: Diagnosing and treating cognitive disorders like amnesia, ADHD, or Alzheimer's disease.
Human-Computer Interaction: Designing user-friendly interfaces based on understanding how individuals process information and interact with technology.
Marketing/Advertising: Creating effective advertising campaigns based on understanding how people attend to, process, and remember information.

Key Figures in Cognitive Psychology

Ulric Neisser: Considered one of the founders of modern cognitive psychology.
George Miller: Known for his research on short-term memory capacity ("magical number seven").
Noam Chomsky: Key figure in linguistics whose work on language has profoundly influenced cognitive psychology.
Jean Piaget: Known for his research on cognitive development in children.
Hermann Ebbinghaus: Early pioneer in memory research; studied forgetting.
