UNC EXSS 380 Exam UPDATED
QUESTIONS AND CORRECT ANSWERS
What processes sensory information ? - CORRECT ANSWER Central Nervous System
What information is being provided to the CNS for processing? - CORRECT ANSWER
Sensory input from periphery
How does the CNS respond to sensory input from periphery? - CORRECT ANSWER Used to
make appropriate motor output
What phenomenon is the CNS considered to be & why? - CORRECT ANSWER "Black Box"
- Internal processes are inferred (inability to measure internal processes)
What is one primarily focused on for information processing? - CORRECT ANSWER
Reaction Time
reaction time (RT) - CORRECT ANSWER Temporal delay between presentation of stimulus
and response initiation
What is reaction time made up of? - CORRECT ANSWER The three stages of information
processing
What are the 3 stages of information processing? - CORRECT ANSWER 1. stimulus
identification
2. response selection
3. response initiation / programming
Stimulus Identification - CORRECT ANSWER Stimulus must be recognized
What are the two substages of Stimulus Identification? - CORRECT ANSWER 1. Stimulus
Detection
,2. Pattern Recognition
Stimulus Detection - CORRECT ANSWER - Sensory organs must detect & transmit info
-Input must be interpreted
Pattern Recogniton - CORRECT ANSWER - movement tasks connected w/ multiple stimuli
Response Selection - CORRECT ANSWER 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? - CORRECT ANSWER environmental
cues
What is the time required to select an appropriate response dependent on? - CORRECT ANSWER
1. # of stimulus-response alternatives
2. Stimulus-Response Compatibility
Response / Initiation Programming - CORRECT ANSWER 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? - CORRECT ANSWER 1. Donder's
Subtractive Method
What are the 3 tasks of increasing complexity in Donder's Subtractive Method? - CORRECT
ANSWER 1. Simple Reaction Time
2. Go/No-go Reaction Time
3. Choice Reaction Time
, Simple Reaction Time - CORRECT ANSWER -Single visual stimulus
-Simple reaction task
-quickest RT
Ex: Press a key with right index finger following light stimulus
go/no-go reaction time - CORRECT ANSWER - two light stimuli (discriminatory)
Ex: press button when green light shows but not red
choice reaction time - CORRECT ANSWER 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... - CORRECT ANSWER increases
Who was the classical experiment of RT conducted by? - CORRECT ANSWER Henry &
Rogers (1960)
long-term memory - CORRECT ANSWER sensory info & motor plans transferred to long-
term storage via practice
-large capacity allows for changes in motor programs
Short Term Sensory Store (STSS) - CORRECT ANSWER - Unlimited information received,
huge capacity, held for brief periods of time
-contains somatosensory, auditory, visual stimuli, kinesthesia, etc.
Short-term memory - CORRECT ANSWER "working memory"
-integrated and processed via conscious effort
-longer wait to recall joint position (proprioception) = cannot remember
