Hick's Law relates to reaction time situations that involve various complexities of movement.

Which of the following has the highest degree of stimulus-response compatibility? Three response buttons are located on a table top;three stimulus lights are located:

The most common performance measure used for inferring the amount of time required for action preparation is:

Consider the following performance situation: You are a basketball player guarding an opponent who has the ball.You know that about 80% of the time in this situation the player will move to your right and take a shot.So,you prepare to move in that direction.But,unexpectedly the player moves to your left.Which of the following describes your RT in this situation?

The abbreviation PRP refers to the ________.

If you need to perform a fast sequence of 3 movements,how will your RT for initiating this movement sequence compare to your RT for initiating a sequence of 6 movements? The RT for the 3 movements will be:

Vigilance research indicates that when we must maintain alertness over long periods of time our motor performance will:

The classic experiment by Henry and Rogers showed that the reaction time (RT)associated with a three-part rapid movement is slower than the RT associated with a one-part rapid movement.

To achieve the fastest reaction time out of the blocks,a sprinter should focus on:

A 3-bit decision will require ________ yes/no decisions to arrive at the correct answer.

If you prepare to move left in a right-left choice movement situation,but the signal tells you to move right,your reaction time will be ________ than if you had prepared to move either direction.

Vigilance tasks involve the long-term maintenance of alertness in situations in which signals that must be responded to occur infrequently and irregularly.

Postural preparation,which occurs prior to performing variations of the same activity,involves the same sequence of activation of postural muscles.

The general finding about the relationship between stimulus-response compatibility and reaction time is that as stimulus-response compatibility relationship becomes more compatible,reaction time becomes ________.

The interval of time between the warning signal and the "go" signal in a reaction time task is called the ________.

If you are standing with your arms at your side,and must move one arm as rapidly as possible to point to a target located at shoulder level in front of you,EMG would show that the muscles you activated first were the:

The _______ effect is the slowing of reaction time when a person must name a color's name but the color is different from the printed name,compared to when the printed name and its color are the same.

Research related to movement complexity has shown that the longer movement preparation time is due to a longer:
