Cognitive Ergonomics Day 1
Cognitive Modeling Method
Other cognitive models: Parallal Design,Keystroke level Model, GOMS
Cognitive modeling is an area of computer science this model can be used to simulate or predict human behavior also to improve human computer interaction
The Human Processor Model
Each processor has a cycle time and each memory has a decay time
Decay Time: Fading of memory due to passage of time
Cycle time: Time taken to process an information
This model allows us to predict the performance of a person/user of doing a task in respect to the time it takes them to understand the said task
to calculate how long does it take to perform a task
Sensation and Perception
Connection of Senses with the perceiving the information
Sensation: when senses receive the stimuli (input)
Perception:process by which the brain selects, organizes, and interprets these sensations
Psychological state: Alertness
Signal detection
Sensory Adaptation
How senses adapt to a constant stimulus
In a way that you prioritize certain stimuli and only response to those
Ability to differentiate between two stimuli
Weber's Law
law which relates to human perception, more specifically the relation between the actual change in a physical stimulus and the perceived change. This includes stimuli to all senses: vision, hearing, taste, touch, and smell.
Types of Senses 1.Five basic senses: Sight, Smell, Sound, Taste and Touch
Sense of Balance 3. Sense of Heat 4. Kineaesthetic
Attention and Retention (Memory)
Cognitive Load
Load due to interpretation
Load due to not knowing
Load from Environment
