Emotional correlates of unirhinal odour identification

摘要: It seems self-evident that smell profoundly shapes emotion, but less clear is the nature of this interaction. Here, we sought to determine whether ability identify odours co-varies with self-reported feelings empathy and emotional expression recognition, as predicted if two capacities draw on common resource. Thirty-six neurotypical volunteers were administered Alberta Smell Test, Interpersonal Reactivity Index an recognition task. Statistical analyses indicated positively correlated odour discrimination in right nostril, while happy fearful facial expressions left nostril. These results uncover new links between olfactory emotion which, given ipsilateral configuration projections, point towards intra- rather than inter-hemispheric The also provide novel support for proposed lateralization expression, give reason further explore diagnostic sensitivity tests because reduced others' emotions can mark onset certain neurological diseases.
