1.Live lecture: intro psychology
When it fits: Use this when a lecturer moves fast through slides, you can only type fragments, and the cues are where you turn those fragments into questions you can actually be tested on.
PSYC 101: Memory, lecture 14, 2026-10-20
Source: Lecture 14, slides 1 to 32 (Prof. Halvorsen) Essential question: Why do we forget most of what we learn, and what slows it down? Related: [[PSYC 101]]
The three-store model
Cues: What are the three stores in the Atkinson-Shiffrin model? / How long does each hold information?
- Atkinson and Shiffrin (1968): sensory memory, short-term memory, long-term memory.
- Sensory: under a second for vision, a few seconds for sound.
- Short-term: about 20 to 30 seconds without rehearsal. Capacity "7 plus or minus 2" (Miller, 1956); newer estimate is about 4 chunks (Cowan, 2001).
- ?? Slide 9: difference between short-term and working memory. Ask in section.
Forgetting curve
Cues: What did Ebbinghaus measure? / What does the curve look like?
- Ebbinghaus (1885) memorized nonsense syllables and tested himself at intervals.
- Steepest loss in the first day; then the curve flattens.
- Each review resets the curve and makes the next drop slower.
Levels of processing
Cues: Why does deep processing beat repetition? / Example of shallow vs deep?
- Craik and Lockhart (1972): meaning-based encoding is remembered better than sound- or look-based encoding.
- Class demo: words judged for meaning were recalled about twice as often as words judged for font.
Summary
Information moves from sensory to short-term to long-term memory, and most of it is lost at the first two steps. Forgetting is fastest in the first day, so the first review matters most. Processing for meaning, not repetition, is what makes something stick. Expect a question comparing Ebbinghaus and Craik and Lockhart.
