Cognition & Communication
Human Cognition
Perception = input
Cognition = thought / process
Cognition (Processing)
Reasoning
Problem Soving
Decision Making
Human attention = filter
Selective: process / do not process
Focused
Divided: keep processing / exclude noise
Selective - Human attention
influenced by
Salience (S): difference / distinctiveness
Effort (EF): trade off / what not processed
Expectance (EX): information alocation / mental model
Value (V): information criticality
Conceptual model
P(A) = (S - EF) + (EX * V)
P(A) = Probability of attention
Human Communication
Communcation = transfer of ideas
Components
Transmitter
Receiver
Cognition Communication
Cognition reception
heavily dependent
on working memory
Situasional Awareness
Recognition
Comprehension
Projection
functions:
Phono-verbal = Visual and spatial perception
Visio-spatial = Sounds and spoken words
Executive = Moderates the other two
we are interested in reception
more frequently than transmission
In any form of communication, context is important
Focused - Human attention
influenced by
S, EF, EX
Value
Perceived Value of current process (Vc)
Perceived value of new process (Vn)
Conceptual Model
P(F) = Vc - (S / EF) + (EX * Vn)
Divided - Human attention
Influenced by
S,EF,EX,Vn
Focus on processs 1 (F1)
Perceived value of process 1 (V1)
Number of Processes (N)
Perceived value of other process i in 1..N (Vi)
Conceptual Model
F1/N = (V1 / Vi) - [(S / EF) / (EX * Vn)]
Passive vs Active Perception
Response Time
RT=NT/2
RT: Response Time
N: Number of items to be examined in the search space
T: Time to examine each item that is not the target
Implication for interface design
Humans and machines interact with each other
Where should the interface designer begin?
each also interacts with the environment
