Study Notes
Memory and Forgetting
- Hermann Ebbinghaus was the first experimental psychologist to study memory.
- Ebbinghaus used lists of non-sense trigrams to examine memory.
- Spacing effects: spaced repetitions are more effective than massed repetitions.
- List length effects: longer lists are more challenging to remember than shorter lists.
- Forgetting curve: memory declines over time.
Theories of Forgetting
- Decay theory: memory fades over time.
- The Brown-Peterson paradigm suggests memory fades within 20 seconds without rehearsal.
- Interference theory: forgetting occurs because of competition between memories.
- Greater competition in memory as we learn more.
- Memories are formed as associations and multiple associations can make recall challenging.
- Consolidation theory: memories are strengthened over time, but new memories are fragile.
- Retrieval induced forgetting: a paradigm supporting inhibition theory.
- Inhibition theory: stronger associations suppress weaker associations during retrieval.
- Retrieval induced forgetting (RIF): retrieving some information hinders recalling related information.
Inhibition Theory Controversy
- Cue Independence of Inhibition Theory: suggests that once an item is inhibited it is harder to remember regardless of the cue.
- Retrieval Dependence Assumption: the competition present at retrieval time is necessary for inhibited memory.
- The theories remain controversial due to limited research and data.
Current Research on Forgetting
- Interference is generally accepted as a cause of forgetting.
- Researchers are still exploring the specific roles of decay, consolidation, and inhibition.
- Computational models play a role in analyzing memory mechanisms.
Learning Outcomes
- Understand different theories of forgetting.
- Explain the evidence for each theory.
- Understand the critical predictions of inhibition theory.
- Understand the strengths and weaknesses of different forgetting functions.
