5. 5 Levels of Processing Framework  Craik & Lockhart (1972)  Type of Processing  Physical Processing > shallow  Meaningful Processing > deep  Trace byproduct of processing  Deeper processing leads to more durable traces

23. 23 Mood & Memory  Memory for items differing in emotion  Pollyanna Principle  Mood Congruence - individual differences studies - experimental manipulation of moods  Mood-State Dependence - Claudia Ucros (1989) - meta-analysis - other variables

27. 27 Explicit vs Implicit Measures of Memory  Explicit memory measures:  recall  recognition  Implicit memory measures:  Word fragment completion  Stem completion  Repetition priming  Role of conscious, deliberate recollection

28. 28 The Critical Distinction  Explicit memory tasks require conscious, deliberate recollection of previous experiences  Implicit memory tasks do not require conscious recollection of previous events e.g., b_ _ k

29. 29 Research with Amnesics  Warrington & Weiskrantz (1970)  Tasks explicit - recognition, recall implicit - mutilated word guessing - stem completion - stem completion e.g. st_ _ _ e.g. st_ _ _  Replicated  Dissociation

30. 30 Dissociation  A variable has an effect on one type of test, but little or no effect on another type of test  A variable has one type of effect if measured by Test A, but a different effect if measured by Test B

31. 31 Research with Normal Adults  Levels of processing and the implicit / explicit distincion  Picture Superiority Effect  Current Status - explanations - applications

32. 32 Levels of Processing: Explicit/Implict Tests truck Semantic (pleasant vs unpleasant) Physical, perceptual Task (# syllables or Upper/lower case?) Higher recall, recognition * ___ Higher--or at least equal performance* ___Implicit Memory Test (e.g. t_u_k) Explicit Memory Test

33. 33 versus. Elephant Picture Superiority Effect 1. 1.Subjects view a series of pictures or a series of words 2. 2.Subjects recall stimuli by writing down names of items -- recall of pictures is higher than recall of words.
