• A number of studies have found that family adversity (e.g., negative
parenting) is positively related to child aggression.
• However, studies (Criss et al., 2002; Lansford et al., 2003) indicated that
positive peer relationships moderate the link between family adversity and
child aggressive behavior.
• Specifically:
• Under HIGH positive peer relationship: FA ® AGG = ns
• Under LOW positive peer relationship: FA ® AGG = sig
• Thus, when is family adversity significantly related to child aggression?
• Answer: when children have poor peer relationships.
• Criss (2001) - ANSmoderator
• A number of studies have found that marital violence is positively related
to child aggression.

,• According to the spill-over hypothesis, this association is mediated by
negative parenting.
• The negativity of the marital dyad spills over the parent-child dyad which
then influences child behavior.
Thus, negative parenting helps explain why marital violence is related to
child behavior. - ANSmediator
•4 bizzaro animal parts
•Stick insect
•Kangaroo Testicle
•Fish Eyeball
•Witchetty Grub
•Each participant is asked to eat each of the animal parts, and time to
retching is measured. - ANSrepeated measures one way anova
•A MANOVA reduces the chances of making a Type I error by running
fewer analyses - ANS•instead of running three separate ANOVAs each with
one DV, run only one MANOVA
•Under certain conditions, a MANOVA may find differences that do not
show up under separate ANOVAs
•A puppy therapy RCT in which we randomized people into three groups:
1.A control group
2.15 minutes of puppy therapy
3.30 minutes of puppy contact
•The outcome is happiness (0 = unhappy) to 10 (happy).

,•Predictions:
1.Any form of puppy therapy should be better than the control (i.e. higher
happiness scores)
2.A dose-response hypothesis that as exposure time increases (from 15 to
30 minutes) happiness will increase too - ANSone way anova
