PSYC1101 Lecture Notes - Lecture 5: Semantic Network, Sensory Memory, Encoding Specificity Principle
Document Summary
Mental processes by which information from the environment is. Stored: made meaningful, retrieved, used, modified, communicated to others. Stranger talks on street: only half realised they were talking to someone else, attention on task on hand - stranger lost, poor memory representation. Attention and memory: memory for faces of strangers we encounter and interact with in every day life is surprisingly poor, 60% error rate in line up identification. External stimulus - sensory memory - stm- ltm. Separate sensory registration: provides coherence and continuity to world, experience a constant flow of information, holds info long enough to work out what it is. Semantic: procedural, duration - bahrick et al 1975, forgetting - 40 years, retrieval failure, capacity - high long term recognition, shepard 1967, standing et all 1970, standing 1973. Maintenance rehearsal: simply repeating information with the intention to keep it around for as long as needed. Bekerian and baddley 1980: 50 participants - 2. 5hrs/day, 84% recalled date of change.
