Background: We explored the relationship between alexithymia and inter
personal behavior, particularly the expression of anger. Methods: Nine
ty-eight college students completed the Toronto Alexithymia Scale. A m
edian split was used to divide participants into a low-alexithymia and
a high-alexithymia group. The experimenter intentionally engaged in a
series of anger-provoking behaviors. Results: Compared to individuals
in the low-alexithymia group, individuals in the high-alexithymia gro
up were more interpersonally avoidant and exhibited more nonverbal ang
er, yet there was a trend for them to describe their lab experience as
more pleasant. Among individuals in the high-alexithymia group, the d
ifferent measures of anger and interpersonal behavior were less strong
ly associated than they were among individuals in the low-alexithymia
group. Conclusions: The results provide evidence of a complex associat
ion between alexithymia and anger, and of the lack of coherence in the
communication of individuals with high levels of alexithymia.
