Answer to Question 1
Eli Finke (2014) and colleagues (Denson, De Wall, & Finke 2012 Finke, De Wall et al.,
2012) recently introduced the I3 theory (pronounced I-cubed theory). This theory
emphasizes the role of self-control in aggression, which we just discussed in the
previous section. The three Is in this theory stand for: 1 . Instigationsocial factors
that often trigger aggressive impulses, such as provocation or social rejection. 2 .
Impel lancepersonality and situational factors that promote the urge to aggress
when encountering instigating factors, such as angry rumination or trait
aggressiveness. 3 . Inhibitionthe various factors of self-control we described in
the previous section. This theory pits the forces of instigation and impel lance on the
one hand against the power of inhibition on the other to determine the likelihood of
aggression. For example, strong provocation coupled with angry rumination can
overpower a person's self-control abilities that have been compromised by alcohol,
resulting in an elevated likelihood of aggression.
