1. Review Questions VI
A psychologist suspected that even if only two colours were used in the Droop experiment there
would be both interference and facilitation. To explore
his hypothesis, he tested 24 subjects(12 good readers and 12 poor readers),
8 in each of the three Droop conditions: control, congruent,
and incongruent. He also suspected good reader would show more interference than poor readers.
(Group 1 is made up of good readers and group two is made up of poor readers.)
Interference is the difference between the control and the incongruent conditions. Facilitation is the
difference between the control and the congruent conditions. First analyze this as a completely
Randomized Design. Provide all descriptive stats, figures, test of assumptions, and contrasts.
Do the data below support his hypothesis?
Group control congruent incongruent
2. How would the analysis change if the conditions (control, congruent, and incongruent were
repeated measures?)
