memory and learning - l2 0.0 / 5 ? PsychologyVisual SystemUniversityAll boards Created by: 10dhallCreated on: 24-01-17 13:50 Who did ebbinghaus conduct his study on? Himself 1 of 20 Outline his method Gave himself a list of 20 nonsense syllables and tested how well he could recall them 2 of 20 What did he find? Law of repetition - the more he rehearsed them, the better able he was at retention 3 of 20 What are the phases of memory? encoding, storage and retrieval 4 of 20 What are the memory stores? Sensory, long term and short term 5 of 20 outline how the multistage model works sensory memory comes automatically, needs to be payed attention to and develops into short term, needs to be rehearsed to become long term memory 6 of 20 Outline sperlings method presented letters in a 4x3 matrix for 50ms asked pps to recall as many as they could 7 of 20 What did he find? roughly only 4 of the letters were recalled 8 of 20 What were his conclusions on the capacity of sensory? Theres a very large capacity 9 of 20 What are the conclusions on the duration? sensory memory decays after about 500ms - anything left in sensory by the time it has elapsed (attention paid) is transferred to stm 10 of 20 Why is attention needed for stm? limits the amount of info that you need to remember 11 of 20 Whats the capacity of STM? 7 units +/- 2 12 of 20 What is the duration of STM 15-20 seconds 13 of 20 What is a criticism of the studies on memory? Pro-active interference- previous trials generate interference- which leads to less retention 14 of 20 another criticism? stm may not be needed for ltm because patients with impaired stm still have ltm 15 of 20 What is the capacity and duration of ltm Unlimited 16 of 20 what is the shape of the serial position curve? starts middle, drops low and then rises to highest 17 of 20 Why is this? Primary and recency effects 18 of 20 What are primary effects? The first few items on the list are more easily remembered 19 of 20 What re recency effects? Better memory for last few items on list 20 of 20
