Q

What is the basis of Donders’ Subtraction Paradigm?

A

Measuring RT in different conditions and then calculating the difference, obtaining the time of the pure mental process.

Q

Which assumptions are made in the Subtraction Method?

A
  1. Processing is serial and successive
  2. The presence and sequence of all stages is known
  3. Pure insertion -> No interaction

Q

What happens according to the AFM, if a task is made more difficult?

A

The output from these processes doesn’t differ in quality. It simply ‘comes out’ later.

Q

What does an interaction between two factors mean, when interpreted according to the AFM?

A

The factors must be acting at the same cognitive stage.

Q

When making a task more difficult in two aspects, how can you graphically examine whether these aspects affect the same stage?

A

If RT is graphed on aspect 1, while stratifying for aspect 2, this results in two lines. If the lines are parallel, the effects are additive and affect different cognitive processes.

Q

When doing a task, there is a speed-accuracy tradeoff. at what point on this spectrum is the theoretical definition of an individual’s speed?

A

At the point where maximum accuracy is achieved while being as fast as possible.

Q

What are four ways of dealing with outliers in terms of RT?

A
  1. Using the Median instead of Mean
  2. Using a trimmed mean
  3. Constructing confidence interval
  4. Eliminating outliers according to a fixed criterion
