Effects of emotional state on lexical decision performance

The effect of emotional state on lexical processing was investigated. Subjects were randomly assigned to either a happy or sad mood condition. Emotional state was then induced by listening to 8 min of classical music previously rated to induce happy or sad moods. Response times and error rates were analyzed in a lexical decision task involving sad words, happy words, and pseudowords. Results suggest that emotion aided the participants in responding to emotion-congruent stimuli. The sad group responded faster than the happy group to sad words and the happy group responded faster than the sad group to happy words. Results are discussed with regard to information processing and emotion.
