Duration – STM & LTM Clearly, LTM can store information for a much longer time than LTM Some researchers have tried to measure their durations exactly:

Overview of LTM. Varieties of LTM Two types of LTM –Semantic memory refers to factual information –Episodic memory refers to autobiographical information.

FORGETTING. Problems with Retrieval (Forgetting)  Availability of memory refers to whether the material is actually there to be retrieved  Accessibility.

Forgetting Aim Identify explanations of forgetting

Retrieval and Forgetting AP Psychology. Forgetting An inability to retrieve information due to poor encoding, storage, or retrieval. Biological Reasons.

MEMORY Explanations for Forgetting. Interference  An explanation for forgetting in terms of one memory disrupting the ability to recall another  This.

Duration is the amount of time a memory lasts in out short term memory. The duration of Short Term Memory lasts up to about seconds and occasionally.

Free recall – explanations of forgetting Describe the theory STM, LTM or both? Supporting studies Evaluation points Trace decayDisplacementInterference Motivated forgetting (repression) Retrieval failure (cue dependant forgetting) Lack of consolidation

Recognition – explanations of forgetting Match the study to the theory… Miller (1956) found that when STM was full up (5 – 9 items) new material would push out the old Godden & Baddeley (1975) showed that divers who learnt a list of words underwater recalled it better underwater than on land and vice versa. Peterson and Peterson found poor recall of trigrams after 18 seconds had passed, if participants had to a distraction task (counting backwards Yarnell & Lynch (1970) showed that concussed American footballers could recall what happened if asked immediately (STM) but could not recall anything when asked 20 minutes later (LTM). Keppel and Underwood found that memory of trigrams was 100% in the first trail but got worse over subsequent trails Glucksberg & Lloyd (1967) showed that words associated with other words that were accompanied by an mild electric shock were recalled worse then control words

Forgetting – AO2 Does this theory explain forgetting in LTM, STM or both? Why? Does this theory explain all forgetting? Why not? Does the evidence to support this theory have high ecological validity? Why? Is there any evidence against this theory? How well does this theory explain the serial position effect (for trace decay, displacement and interference)
