Question

In a free immediate recall experiment, participants are given a list of words that are all semantically associated with a critical word (like bed, slumber, pillow, nap, etc.). The critical word (sleep) is not present in the list. Participants often falsely remember the critical word when recalling the list.

One researcher would like Group A to see a list of 5 words and Group B to see a list of 10 words.

The other researcher would like Group A to see a list of 10 words and Group B to see a list of 50 words.

Which research design do you think would be more likely to show a significant group difference? Consider the strength of your manipulation and the possibility of floor/ceiling effects in your answer.

Explanation / Answer

the researcher with more samole data have greater chance of getting better results.

The critical word may not be as useful when the sample is too small whereas in a larger sample the chance of mis interpretation of the critical word increases and hence may give better results in the experiment.
