{{BloomIntro}}
Cognitive Psychology is the scientific study of mental processes such as "attention, language use, memory, perception, problem solving, creativity, and thinking." Often described as the "science of the mind," it treats the brain as an information processor, similar to a computer. By using experimental methods to uncover the "internal software" of the human experience, cognitive psychologists aim to understand how we acquire, store, and use knowledge. This field has transformed our understanding of learning, decision-making, and the nature of human intelligence.

* '''Cognitive Psychology''' — The study of mental processes and how they influence behavior.
* '''Information Processing Model''' — A framework comparing the mind to a computer (Input -> Process -> Output).
* '''Attention''' — The cognitive process of selectively concentrating on one aspect of the environment.
* '''Working Memory''' — A system for temporary storage and manipulation of information.
* '''Long-Term Memory''' — The relatively permanent and limitless storehouse of the memory system.
* '''Schema''' — A mental framework that helps organize and interpret information.
* '''Heuristic''' — A mental shortcut or "rule of thumb" used to solve problems quickly.
* '''Algorithm''' — A methodical, logical rule or procedure that guarantees solving a particular problem.
* '''Concept''' — A mental grouping of similar objects, events, ideas, or people.
* '''Prototype''' — A mental image or "best example" of a category (e.g., a robin is a prototype of 'bird').
* '''Insight''' — A sudden and often novel realization of the solution to a problem ("Aha!" moment).
* '''Functional Fixedness''' — The tendency to think of things only in terms of their usual functions (a block to creativity).
* '''Metacognition''' — "Thinking about thinking"; awareness and understanding of one's own thought processes.
* '''Cognitive Load''' — The amount of mental effort being used in the working memory.

== <span style="color: #FFFFFF;">Understanding</span> ==
Cognitive psychology shifted the focus from "Behaviorism" (only looking at what people ''do'') to looking at what people ''think''.

'''The Computational Metaphor''':
* '''Hardware''': The Brain (neurons and synapses).
* '''Software''': Cognitive processes (algorithms for vision, memory, etc.).
* '''Input''': Sensory data (sight, sound).
* '''Storage''': Memory systems.

'''Schemas and Categorization''': We don't store every detail of every object. We store "Schemas." If I say "restaurant," you immediately have a schema of a menu, tables, and a waiter. This allows for fast processing, but it also leads to '''Stereotypes''' and '''False Memories''' (you might "remember" seeing a menu even if the restaurant didn't have one because it's part of your schema).

'''The Limits of Thinking''': Our working memory is a "bottleneck." We can only hold about 7 (±2) chunks of information at once (Miller's Law). To overcome this, we use '''Chunking''' (grouping info) and '''Heuristics''' (shortcuts). While shortcuts are fast, they lead to predictable '''Cognitive Biases''' (like the Availability Heuristic or Confirmation Bias).

'''Modeling 'Chunking' for Memory Improvement:'''
<syntaxhighlight lang="python">
def memorize_sequence(sequence):
    """
    Shows how chunking reduces cognitive load.
    """
    raw_len = len(sequence)
    
    # Chunking into groups of 3
    chunks = [sequence[i:i+3] for i in range(0, len(sequence), 3)]
    num_chunks = len(chunks)
    
    return {
        "Raw Items": raw_len,
        "Chunked Items": num_chunks,
        "Efficiency Gain": f"{(1 - num_chunks/raw_len)*100:.1f}%"
    }

# 12-digit number (hard to remember at once)
phone_num = "123456789012"
print(memorize_sequence(phone_num))
# Remembering 4 'chunks' is much easier than 12 'bits'.
</syntaxhighlight>

; Cognitive Strategies for Success
: '''Spaced Repetition''' → Leveraging the "spacing effect" to build long-term memory.
: '''Dual Coding''' → Combining words and visuals to create more "hooks" in the brain.
: '''Lateral Thinking''' → Solving problems through an indirect and creative approach (breaking functional fixedness).
: '''Self-Explanation''' → Explaining a concept to yourself (or others) to find "gaps" in your mental model.

'''The Nature of Intelligence''': Is intelligence one thing ("g" factor) or many things? Cognitive psychologists analyze intelligence through models like '''Cattell-Horn-Carroll (CHC)''', which divides it into "Fluid" (solving new problems) and "Crystallized" (stored knowledge) intelligence. Analyzing these components helps in designing better IQ tests and educational tools.

== <span style="color: #FFFFFF;">Evaluating</span> ==
Evaluating cognitive models:
# '''Predictive power''': Does the model accurately predict how long it will take a person to solve a specific puzzle?
# '''Generality''': Does the "Working Memory" model apply across all cultures and languages?
# '''Biological Plausibility''': Can the proposed "mental structure" (like a schema) be mapped to actual neural networks?
# '''Handling Anomalies''': How does the theory explain "Expertise" (where people seem to bypass the 7-chunk limit)?

Future Frontiers:
# '''Cognitive Augmentation''': Using "Nootropics" or "Brain Stimulation" (tDCS) to enhance memory and focus.
# '''AI and Human Cognition''': Designing "Human-Centered AI" that works ''with'' our cognitive biases rather than against them.
# '''The Science of Creativity''': Using fMRI to understand the "Divergent Thinking" process and how to teach it.
# '''Digital Detox''': Researching how "constant connectivity" is altering our ability to reach "Deep Work" and sustained attention.
