EXSS 380 EXAM 2 QUESTIONS AND ANSWERS
1.For a simple reaction time experiment, subjects must perform two different tasks in
response to the same stimulus. The first task (Task 1) involves flexing the elbow as
quickly as possible. The second task (Task 2) involves flexing the elbow as quickly as
possible and then making contact with a suspended tennis ball. For which task would
we expect a longer reaction time? - Answers :task 2
A motor control researcher asks subjects to perform two tasks. The primary difference
between the two tasks is that one involves more "moving parts" than the other. Though
the stimulus for each task is identical, and the subjects are aware of the movement they
are to perform, the researcher notices that the reaction time increased as the number of
moving parts increases. What stage of information processing is most likely influenced
by this experiment?
• A. Response selection
• B. Response programming
• C. Stimulus identification - Answers :response programming
3.According to Hick's Law, which of the following experimental conditions produces the
longest reaction time?
A. Press a key when you see a light
• B. Press a key when you see a blue light (Go/No Go reaction time tests)
• C. Press the right key for a blue light and the left key for the red light (Choice reaction
time tests) - Answers :C
4._____ refers to cues that trigger recall of prior exposures.
• A. Declarative encoding
• B. Priming
• C. Parallel Processing
• D. Proprioception - Answers :priming
5.If multiple sensory inputs are processed simultaneously, they are said to be
processed in serial.
T/F - Answers :false
6. In which of the following scenarios would we expect the shortest reaction time?
A. Direct finger vibration under 6 fingers with a single response
• B. A single visual stimulus with a single response
