ICS 463: Intro to Human Computer Interaction Design 2. Cognitive Frameworks Dan Suthers
Information Processing Psychology Humans as information processors Attention Encoding Comparison Response Selection Response Execution Memory
Multi-Store Model of Memory Sensory: milliseconds Iconic Auditory Short Term (Working): seconds “The magic number 7 plus or minus 2” Long Term: permanent(?)
Information-Processing HCI Model Human Processor Perception Cognitive Motor GOMS (Goals, Operations, Methods and Selection) quantitative predictions of performance
Variants on Information Processing Computational Scripts, Plans, Goals and Memory Parallel Distributed Processing (Connectionist) Brain metaphor
Distributed/Situated Cognition Cognition is distributed across individuals and artifacts “Cognition in the wild”: Study cognitive activities as embodied and situated in a context
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
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
