3 stage information processing model

stimulus identification --> response selection --> response programming -->

stimulus identification

receives information from senses

identifies and classifies information

extract relevant information

response selection

decide on a plan of action

translate between stimulus and response

response programming

organize and prepare a response

send appropriate motor commands

what is SR compatibility

degree of natural or learned correspondence between a stimulus and a response

affects how easy it is to translate input to the response you need to give (output)

compatibility is

the degree to which relationships are consistent with human expectations... where compatibility relationships are designed into the systems...

learning is faster, reaction time is faster, fewer errors are made, and user satisfaction is higher

types of compatibility (4)

conceptual compatibility, movement compatibility, modality compatibility, spatial compatibility

conceptual compatibility

degree to which codes and symbols correspond to people's conceptual associations

movement compatibility

degree to which correspondence between movements of displays and controls and response of system being controlled

modality compatibility

degree of correspondence between stimulus-response modalities

spatial compatibility

compatibility in spatial arrangement of controls and displays, or stimulus and responses

why study S-R compatibility phenomena

pervasive effects evident in performance of simple laboratory tasks, everyday perceptual-motor interactions, to complex human-machine interactions

provides a measure and theoretical insight into basic cognitive processes that occur between perception and action

ipsilateral mapping (same)

contralateral mapping (opposite)

cognitive coding vs neuroanatomical correspondence

are spatial compatibility effects due to cognitive coding of stimulus and response relations?

or are they due to the anatomical relations between the cerebral hemispheres processing the stimulus and response

spatial compatibility effects

spatial compatibility effects are not due to anatomical circuits between cerebral hemispheres processing the stimulus and response

they are a function of the cognitive translation of stimulus and response representations

S-R compatibility proper

what would be compatible? incompatible?

...

simon effect protocol

respond to stimulus feature

location of stimulus is irrelevant

stimulus features are mapped to spatial response

response competition

SR correspondence can affect performance in what two ways

abrupt stimulus onset automatically primes spatially corresponding response - generates spatial code

task-dependent S-R transformation is applied in order to intentionally translate the stimulus code into the appropriate response
