PSY 3213 Exam Questions with 100% Verified Answers
Bower, Gilligan, and Monterio (1981) hypothesized that people would notice and remember
events in stories that were consistent with their mood. Participants were put into either a
happy or a sad mood. All participants then read two stories, one of which was happy and one
of which was sad. What was the design of the experiment?
a. one variable within-subjects
b. within-subjects factorial design
c. one variable between-subjects
d. mixed factorial design
mixed factorial design
With a synergistic interaction,
a. higher levels of one independent variable increases the effect of another independent
variable
b. higher levels of one independent variable decrease another independent variable
c. there is a main effect of one independent variable but not the other
d. None of these are true. You can't interpret a synergistic interaction without knowing which
independent variable you are talking about
higher levels of one independent variable increases the effect of another independent variable
Dr. Caster decides to perform an experiment investigating the effects of caffeine and sugar on
motor skill performance. He randomly assigns his subjects to one of four groups: high
caffeine/high sugar, high caffeine/no sugar, no caffeine/high sugar, no caffeine/no sugar.
People in each group are given a soft drink containing the appropriate levels of sugar and
caffeine, and then tested on a mirror tracing task. Dr. Caster finds that the people in two of
the groups (the high caffeine/high sugar and the no caffeine/no sugar) perform at about the
same high level, while the other two groups (the no caffeine/high sugar and high caffeine/no
sugar) perform at about the same poor level. Dr. Caster's results show
a. a synergistic interaction
, b. a main effect of caffeine
c. an antagonistic interaction
d. a main effect of sugar
an antagonistic interaction
In a two-by-two mixed factorial design,
a. Each subject experiences only one level of one independent variable and all levels of the
other independent variable
b. Each subject experiences all levels of both independent variables
c. Each subject experiences one level of each of the independent variables
d. Reliability is diminished
Each subject experiences only one level of one independent variable and all levels of the other
independent variable
If a factorial design is conducted in which each subject experiences each condition at least
once, then it is a
a. between subjects design
b. within subjects design
c. mixed design
d. all of these
within subjects design
Barnes, Ickes, and Kidd (1979) studied whether or not students would lend their notes to a
classmate by varying the intentionality of the needy student (unintentional vs attentional)
and the stability of their request (always vs sometimes). Participants received one request
from one needy student. What was the design of the experiment?
a. one variable between-subjects
b. between-subjects factorial design
c. one variable within-subjects
d. within-subjects factorial design
