memory evaluations

artificial stimuli - used artificial stimuli than meaningful material no meaning to participants so lacks generalisability to other memory tasks
1 of 11
lacking validity - conducted a long time ago so lacks good control, some participants may have been distracted
2 of 11
high external validity - real life memories were studied so higher recall
3 of 11
multi store model
more than 1 type of STM - patient with amnesia worse recall when asked t recall digits, better when he read digits to himself
4 of 11
types of LTM
clinical evidence - clive&henry episodic memory severely impaired but procedural and semanti not. Neuroimaging - part. asked to do memory taks whilst in PET scan, pro and sem found in prefrontal cortex. Real life applications
5 of 11
working memory model
clinical evidence, patient KF - process visual info normally not sounds. supports separate stores. Dual task performance part had more difficulty doing2 visual tasks than visual& verbal - must be separate slave system

lab studies- 1000s been carried out - shows interferecne is very iikely exp. for forgetting. Artifical materials - use of artificial materials imakes it more likely in the lab than real life
7 of 11
retrieval failure
supporting evidence - carter/cassiday godden/baddely helps increase validity. Questioning context effect- baddeley, learning in 1 room and recalling in another has no actual effect on forgetting
