Abstract Previous studies have suggested that subjects are slower to colour-name emotional words, when the meaning of these words is related to a fear or current concern. We carried out three experiments on subjects having either high or low fear of snakes, with the aim of replicating this finding, and of testing the effects of arousing fear in subjects at the same time. Unexpectedly, we could only replicate the predicted interference effect in the absence of threat, whether due to a snake or to another threatening stimulus. We conclude that emotional interference effects do depend on high levels of fearfulness or trait anxiety, and on a match between the content of the subjects' concerns and the meaning of the interfering material. However, this interference may be paradoxically obscured by fear arousal, or the presence of a real danger that alters processing priorities in highly fearful subjects.
