Interference theory explains forgetting due to conflicting information in memory. Proactive interference occurs when old memories disrupt new ones, while retroactive interference involves new memories interfering with old ones. The theory emphasizes the impact of similarity on memory recall and is supported by both laboratory and real-life studies, though it has limitations in explaining all instances of forgetting.
Key points:
- Two types of interference: proactive and retroactive
- Similarity between memories increases interference
- Supported by lab studies like McGeoch and McDonald (1931)
- Real-life applications demonstrated by Baddeley and Hitch (1977)
- Time between learning and recall may affect interference
- Cues can help overcome interference effects
