Document Summary
Selective attention: the monitoring of several information sources at one time in order to successfully perform a task. Performance declines as the number of sources increase (load stress) If the operator is under some degree of external stress, even fewer sources of info can be monitored successfully. Change blindness: unaware of the things going on around you. Inattention blindness: something has gone on in the environment that you don"t. Several factors influence attentional focusing in tasks that involve human-machine interaction: the physical proximity of the info sources, anything that serves to make the info more distinct (brighter, louder etc. ) Word processing is significantly faster than color processing. Ink colour and word are initially processed in parallel (together) Interference is caused later when the two stimuli compete for different responses. Required suppressing of semantic content (naming the colour of the word requires the word name be suppressed)
