Cognition

Secondary

How the mind encodes, stores, transforms, and sometimes fails to retrieve the world it builds from sensation.

This collection covers cognitive psychology, including thinking and problem-solving, decision making and cognitive biases, language and cognition, memory stages and types, factors affecting memory, sensory and perceptual processes, and theories and testing of intelligence. Aligned with the IPsyO (International Psychology Olympiad) syllabus.

1. Cognition

Thinking, deciding, and talking — how the mind processes information, where it cuts corners, and which corners consistently trip it up.

2. Memory

Memory as a three-stage system — and the characteristic ways each stage fails or reconstructs what it claims to recall.

3. Perception

From raw sensation to organized perception — how the Gestalt tradition and modern research explain what the brain adds to the retinal image.

4. Intelligence

Intelligence as a measurement problem — what psychometrics captures, what it misses, and what heritability actually tells us.

What You'll Walk Away With

  • 1cognitive biases taxonomy card grouping heuristics (availability, representativeness, anchoring) and biases (confirmation, framing, hindsight) by the underlying mental shortcut they exploit
  • 1memory stages diagnostic map pinpointing whether a failure is at encoding, storage, or retrieval and what the typical cause is at each stage
  • 1perceptual organization key listing the Gestalt grouping principles (proximity, similarity, continuity, closure, common fate) with concrete visual examples
  • 1intelligence theories comparison table contrasting Spearman's g, Gardner's multiple intelligences, Sternberg's triarchic theory, and the CHC hierarchy on what they include and what they exclude
  • 1language levels hierarchy mapping phonemes → morphemes → syntax → semantics → pragmatics so each linguistic analysis targets the right level

You'll Have Answers To

  • ?Why is every memory a reconstruction rather than a replay — and what does that imply about eyewitness testimony?
  • ?When a decision goes wrong because of a cognitive bias, which specific mental shortcut misfired — and why does that shortcut exist?
  • ?How does perception 'see' depth, motion, and constancy from a flat, changing retinal image?
  • ?Is intelligence one thing (Spearman's g) or many (Gardner, Sternberg) — and what does the answer depend on?
  • ?What does it really mean to say IQ is '50% heritable' — and what does that statistic not say?

Editor's Note
“Cognitive psychology as a working diagnostic toolkit”

This collection treats cognition the way a mechanic treats an engine — encoding, storage, retrieval, attention, and perception each named as separable stages with distinct failure modes. The sections on memory construction and decision-making biases are especially sharp: they replace the textbook greatest-hits with a usable map of how the mind actually behaves under load.

Editor's Brief
Who it's for
Students preparing for IPsyO, AP Psychology, or any introductory cognitive science course where memorizing definitions won't cut it and the exam wants you to reason about mechanism.
What stands out
Every cognitive process is introduced with the failure modes that reveal it — memory through forgetting curves and false memory, perception through illusions and constancies, intelligence through measurement controversies.
Read if
You want to understand the mind as an information-processing system with specific bottlenecks and specific reconstructive habits — not as a generic 'brain does thinking' black box.
Gold Quotes
Memory does not store experiences — it stores fragments and rules for reassembling them. Every recall is a reconstruction, shaped by schemas, mood, and the questions you're being asked.

Loftus's misinformation research, Bartlett's 'War of the Ghosts,' and the eyewitness-testimony literature all point to the same finding: the act of remembering is itself a kind of editing. This is why leading questions can implant details, why expectations warp recall, and why a confident memory and an accurate memory are not the same thing.
