title: Sensorimotor and linguistic information attenuate emotional word processing benefits: an eye-movement study.
abstract: Recent studies have reported that emotional words are processed faster than neutral words, though emotional benefits may not depend solely on words' emotionality. Drawing on an embodied approach to representation, we examined interactions between emotional, sensorimotor, and linguistic sources of information for target words embedded in sentential contexts. Using eye-movement measures for 43 native English speakers, we observed emotional benefits for negative and positive words and sensorimotor benefits for words high in concreteness, but only when target words were low in frequency. Moreover, emotional words were maximally faster than neutral words when words were low in concreteness (i.e., highly abstract), and sensorimotor benefits occurred only when words were not emotionally charged (i.e., emotionally neutral). Furthermore, emotional and concreteness benefits were attenuated by individual differences that attenuate and amplify emotional and sensorimotor information, respectively. Our results suggest that behavior is functionally modulated by embodied information (i.e., emotional and sensorimotor) when linguistic contributions to representation are not enhanced by high frequency. Furthermore, emotional benefits are maximal when words are not already embodied by sensorimotor contributions to representation (and vice versa). Our work is consistent with recent studies that have suggested that abstract words are grounded in emotional experiences, analogous to how concrete words are grounded in sensorimotor experiences.
