Emotional prosody perception (EPP) unfolds in time given the intrinsic temporal nature of auditory stimuli, and has been shown to be modulated by spatial attention. Yet, the influence of temporal attention (TA) on EPP remains largely unexplored. TA studies manipulate subject's motor preparedness according to an upcoming event, with targets to discriminate during short attended trials arriving quickly, and, targets to discriminate during long unattended trials arriving at a later time point. We used here a classic paradigm manipulating TA to investigate its influence on behavioral responses to EPP (n = 100) and we found that TA bias was associated with slower reaction times (RT) for angry but not neutral prosodies and only during short trials. Importantly, TA biases were observed for accuracy measures only for angry voices and especially during short trials, suggesting that neutral stimuli are less subject to TA biases. Importantly, emotional facilitation, with faster RTs for angry voices in comparison to neutral voices, was observed when the stimuli were temporally attended and during short trials, suggesting an influential role of TA during EPP. Together, these results demonstrate for the first time the major influence of TA in RTs and behavioral performance while discriminating emotional prosody. Show more
