Answers
What processes sensory information ? - ANSW-Central Nervous System
What information is being provided to the CNS for processing? - ANSW-Sensory input from periphery
How does the CNS respond to sensory input from periphery? - ANSW-Used to make appropriate motor
output
What phenomenon is the CNS considered to be & why? - ANSW-"Black Box"
- Internal processes are inferred (inability to measure internal processes)
What is one primarily focused on for information processing? - ANSW-Reaction Time
reaction time (RT) - ANSW-Temporal delay between presentation of stimulus and response initiation
What is reaction time made up of? - ANSW-The three stages of information processing
What are the 3 stages of information processing? - ANSW-1. stimulus identification
2. response selection
3. response initiation / programming
Stimulus Identification - ANSW-Stimulus must be recognized
What are the two substages of Stimulus Identification? - ANSW-1. Stimulus Detection
2. Pattern Recognition
Stimulus Detection - ANSW-- Sensory organs must detect & transmit info
-Input must be interpreted
Pattern Recogniton - ANSW-- movement tasks connected w/ multiple stimuli
Response Selection - ANSW-decision on what to do after collecting and processing information
-Hick's Law: as # of stimulus-response alternatives increases, so does choice RT (can be reduced by
practice)
What is the response selection stage influenced by? - ANSW-environmental cues
What is the time required to select an appropriate response dependent on? - ANSW-1. # of stimulus-
response alternatives
2. Stimulus-Response Compatibility
Response / Initiation Programming - ANSW-cannot be initiated until the stimulus is identified & the
appropriate response is selected
, - most voluntary responses are received from "motor memory" (Feedfoward/motor programs)
-Henry & Rogers: as movement complexing increases, RT increases
What is the evidence of information processing? - ANSW-1. Donder's Subtractive Method
What are the 3 tasks of increasing complexity in Donder's Subtractive Method? - ANSW-1. Simple
Reaction Time
2. Go/No-go Reaction Time
3. Choice Reaction Time
Simple Reaction Time - ANSW--Single visual stimulus
-Simple reaction task
-quickest RT
Ex: Press a key with right index finger following light stimulus
go/no-go reaction time - ANSW-- two light stimuli (discriminatory)
Ex: press button when green light shows but not red
choice reaction time - ANSW-two types of stimuli and two types of responses
-longest RT
EX: press button w/ left hand when there's green light; press button w/ right hand when there's red
button
As movement complexity increases, Reaction time... - ANSW-increases
Who was the classical experiment of RT conducted by? - ANSW-Henry & Rogers (1960)
long-term memory - ANSW-sensory info & motor plans transferred to long-term storage via practice
-large capacity allows for changes in motor programs
Short Term Sensory Store (STSS) - ANSW-- Unlimited information received, huge capacity, held for brief
periods of time
-contains somatosensory, auditory, visual stimuli, kinesthesia, etc.
Short-term memory - ANSW-"working memory"
-integrated and processed via conscious effort
-longer wait to recall joint position (proprioception) = cannot remember
where is info from STSS and long-term memory integrated? - ANSW-Short-term memory
