Chapter 7: Memory and Training
2
OVERVIEW
3
Representation of memory functions
4
Working memory
5
Working memory model Phonological store (loop) Visuo-spatial sketchpad
Central executive Episodic buffer. Central Executive Articulatory Loop Phonological Store
6
Working Memory Interference
Code Interference Verbal-phonetic versus visual-spatial code interference Interference in the Central Executive Central-executive intensive tasks (random number generation)
7
Working Memory, the Central Executive and Executive Control
Working memory capacity Roles of central executive To temporary hold & manipulate info in LTM To change retrieval strategies from LTM To coordinate performance on multiple tasks To attend selectively to stimuli
8
Matching Display with Working Memory Code
Stimulus/central processing/response compatibility. Echoic and iconic memory
9
Limitations of Working Memory
Duration Brown-Peterson paradigm. Capacity Relationship with speed of rehearsal. Magic number 7 ± 2 Chunking Chunks of information Parsing
10
Interference & confusion
11
Proactive and Retroactive Interference
Relationship between interference, and space and similarity Implications of design Working memory analysis
12
EXPERTISE AND MEMORY
13
Expertise General characteristics Intrinsic versus contrived tasks
14
Expertise and Chunking
Template theory and chunking Chunking strategies Novice versus expert differences
15
Skilled Memory and Long Term Working Memory
Limitations of chunking based accounts Long-term working memory theory
16
EVERYDAY MEMORY
17
Prospective Memory Effects of delay on PM performance
PM and motivation Implementation intention and strategies to improve PM
18
Transactive Memory (System)
Properties of a TMS Specialization, coordination and credibility Collaborative inhibition How it can be reduced TMS and team performance
19
SITUATION AWARENESS
20
Working Memory and Expertise in Situation Awareness
Evidence for links between WM and SA Role of LTWM in SA
21
Levels of SA and Anticipation
Endsley’s Three levels of SA Perception Comprehension Projection Mechanisms by which anticipation is accomplished
22
Measuring SA and the Role of Anticipation
SAGAT SPAM Implicit performance-based measures
23
PLANNING AND PROBLEM SOLVING
24
Planning and Problem Solving
Role of working memory and difficulty Satisficing problem solving and opportunistic planning Supporting planning and problem solving Visualization Heuristic strategies in problem solving Training to support team problem solving Heterogeneous and homogeneous pairs
25
TRAINING
26
Transfer of Training Measuring transfer -- Transfer effectiveness ratio.
27
Transfer of Training Training system fidelity
Realism, complexity, workload and learning outcome
28
Transfer of Training Negative transfer
Similarity of stimulus and response elements between old and new task.
29
Training Techniques and Strategies
Cognitive Load Theory Intrinsic load, germane load and extraneous load Training support and error prevention: Reducing intrinsic load Worked examples and scaffolding Task simplification: Reducing intrinsic load adaptive training
30
Training Techniques and Strategies
Part task training: Reducing intrinsic load
31
Training Techniques and Strategies
Part task training: Reducing intrinsic load time sharing skills, and variable priority training Active learning: Increasing germane load generation effect, and active versus passive learning
32
Training Techniques and Strategies
Multi-media instruction: Decreasing extraneous load dual-coding principle Feedback Practice and overlearning
33
Training Techniques and Strategies
Expertise effect Distribution of practice Training-transfer dissociation
34
LONG TERM MEMORY: REPRESENTATION, ORGANISATION, AND RETRIEVAL
35
Knowledge Representation
Procedural versus declarative knowledge Implicit, semantic and episodic memory Knowledge elicitation to extract domain knowledge from experts
36
Knowledge Representation
Knowledge organisation Implications for design of menus Mental model Role, novice versus expert differences
37
Knowledge Representation
Methods for representing long-term knowledge Work domain analysis, observations and interviews, protocol analysis
38
Memory Retrieval and Forgetting
Recall and recognition Implications for design of computer interfaces, remember-know paradigm, retrieval cues, and retrieval induced forgetting Event memory Accuracy, misinformation effect
39
Skill Retention Skill type, sequence of practice, individual differences
