Subjects performed an idiographic, computerised version of the modifie
d Stroop colour-naming task after having undergone a him-induced mood
manipulation designed to produce either anxiety, elation, or a neutral
mood. The Stroop stimuli were words related either to the subject's p
ositive current concerns (e.g. goals, interests), to the subject's neg
ative current concerns (e.g. personal worries), or to neither. The res
ults indicated that words strongly related to subject's positive as we
ll as to negative current concerns produced significantly more Stroop
interference than did words unrelated or weakly related to their curre
nt concerns. Although the films strongly influenced the subjects' mood
s in predicted directions initially, mood changes were largely not mai
ntained throughout the experiment. Thus, it is not surprising that no
significant interactions with word type were found. These results indi
cate that the ''emotional Stroop effect'' occurs in normal subjects as
well as in anxious patients, and occurs with positive as well as with
negative material of strong personal relevance.
