The time course of mood-induced decrements in colour-naming of threat-related words

The current study investigated the relationship between processing biases towards affectively negative words and a film-based mood manipulation procedure. Subjects either watched a film about nuclear war or sat alone for ten minutes and then colournamed sets of negative, positive and neutral words. Testing occurred after one of three possible time intervals. Impaired colour-naming of negative words was found both immediately and five minutes after watching the film. There was no consistent pattern of colour-naming impairments for the positive words. It was found that, when baseline Stroop performance was taken into account, and the semantic priming effect caused by stimulus homogeneity was controlled for, the resulting impairment in the colournaming of negative words was accounted for by state anxiety levels alone, and not the previously found interaction of state and trait anxiety.
