In this experiment we examined the attribution of guilt as a function
of speech accommodation and crime type. The subjects (129 White, Engli
sh-speaking, South African students) listened to tape-recorded exchang
es between a Coloured, Cape Afrikaans-speaking criminal suspect and a
White, English-speaking interrogator. The subjects were asked to rate
the suspect on a 7-point scale ranging from innocent (7) to guilty (1)
. The independent variables were (a) type of language shift (convergen
ce, partial divergence, complete divergence) and (b) type of crime (bl
ue-collar, white-collar). As we predicted (based on speech accommodati
on theory), the suspects who converged into English were rated as sign
ificantly less guilty than those who diverged into Cape Afrikaans. Fur
thermore, the suspects accused of blue-collar crimes were more often d
eemed guilty than were those accused of white-collar crimes (cf. Seggi
e, 1983).
