Information Processing: 3-stage approach
{Input} Stimulus Identification → Response selection →Response programming {Output}
• Similar to how a computer processes information
• Stages of information processing are serial and discrete
Stimulus Identification Stage
• Stimulus Detection- Sensory information attained from external sources is detected and
transformed into neurological signals
o Neurological signals are mapped onto a meaningful event
o Raw material to Bioelectrical signal
o Eg. This aseall is approahig y fae at high rate of speed
• Pattern Recognition – Can be a natural or trained phenomenon
o Extracting patterns or features from environmental stimuli for use in latter stages of info
processing
o Training pattern recognition can optimize performance in temporarily demanding sports
o So during game they can recognize the pattern after training so you can make quick
decision on what to do
o You become aware of the stimulus
Chase and Simon Study
• Looked at pattern recognition in 3 groups
• Chess maters, amateur chess players and beginners
• 3 groups sat in front of screen and showed slides very quickly
• They showed a chess board with chess pieces for 100 milliseconds
• In real game situation, the chess pieces depicted where they could be in a game scenario
• Second game, the random one- they were just random
• Asked them to tell the positions of the chess pieces
• Recall accuracy was measured
Results-
• Real game- chess maters had better performance throughout 3 trails and got to 100% accuracy
ad egiers did’t.
o Random game situation- Chess masters had terrible performance. Accuracy for
amateurs and beginners had better recall accuracy
• Specificity of pattern recognition- you only get good at pattern recognition for your own
domain. (aka in this situation, real game situation.)
X-ray of an Ankle
• Diagnosing is pattern recognition
• Physicians and attending should be trained in pattern recognition
