EXSS 380 Quiz #2 Questions with Solved
Solutions 2026/27 Update.
why is the CNS considered to be a "black box"? - Answer due to its inability to measure
internal processes
the information processing model is primarily focused on... - Answer reaction time
3 stages of information processing? - Answer stimulus identification
response selection
response initiation/programming
simple reaction time - Answer 1 stimulus, 1 response
ex: light stimulus and press a key
200ms
Go/No-go reaction time - Answer 2 stimulus, 1 response
ex: red = go, blue = no go
230ms
Choice reaction time - Answer 2 stimuli
2 response
ex: red = right, blue = left
285
Donder's model suggests information is processed centrally in a _________ manner;
Research suggests that these processes occur in... - Answer serial (sequential);
series & parallel (simultaneously)
2 stages of stimulus identification - Answer stimulus detection and pattern recognition
determination of the appropriate response selection is influenced by... - Answer
environmental cues (ex: bball player setting a screen on you)
, the time required to select the appropriate response is dependent on what? - Answer 1.
number of stimulus-response alternatives
2. stimulus-response compatibility
Hick's Law - Answer as the number of response alternatives increases, so does choice reaction
time
with Hick's Law, the time required to choose a response is ____________ to amount of info that
must be processed in a making decision - Answer linearly related
what are some exceptions to Hick's Law? - Answer 1. practice and experience
2. digit recall task
3. direct finger vibration
4. eye movements toward vs. away from target
most voluntary responses are complex in nature and retrieved from... - Answer "motor
memory"
Henry and Rogers experiment depicts... - Answer as movement complexity increases, reaction
time increases
short term sensory store - Answer capacity to store massive amounts of sensory info for brief
periods of time
short term memory - Answer buffer area for STSS and long term memory
_______ is often referred to as "working memory" - Answer short term memory
short term memory has _________ capacity and _________ duration - Answer limited (~7
items); short
Sensory info can be transferred to long-term storage via... - Answer rehearsal/practice
ex: riding a bike
sensory info is integrated by the CNS into 2 types of info critical to neuromuscular control: -
Answer proprioception
kinesthesia
