2. Cognitive Frameworks
Dan Suthers

3. Information Processing Psychology
Humans as information processors
Attention
Encoding
Comparison
Response
Selection
Response
Execution
Memory

4. Multi-Store Model of Memory
Sensory: milliseconds
Iconic
Auditory
Short Term (Working): seconds
“The magic number 7 plus or minus 2”
Long Term: permanent(?)

5. Information-Processing HCI
Model Human Processor
Perception
Cognitive
Motor
GOMS (Goals, Operations, Methods and Selection)
quantitative predictions of performance

6. Variants on Information Processing
Computational
Scripts, Plans, Goals and Memory
Parallel Distributed Processing (Connectionist)
Brain metaphor

7. Distributed/Situated Cognition
Cognition is distributed across individuals and artifacts
“Cognition in the wild”: Study cognitive activities as embodied and situated in a context

8. Analysis of Functional Systems
How information is propagated through the technological, cognitive, social, and organizational system
How information is transformed between different representational states of objects in the system, with consequences for action
Situation awareness: implicit as well as explicit communication

9. Analysis of Breakdowns
How coordination of activities breaks down due to interactions between multiple components of the functional system
Ways of improving the functional system
Example: Shared displays
