The present study used a cross-splicing method to explore whether and how aging affects the recognition of emotional speeches. Two experiments were set to better understand this issue. A behavioral experiment was designed to quest whether aging has a negative influence on the process of emotional prosody recognition. Thirty elderly participants (ages 50-60) were invited into the experiment as the elder-group and thirty younger participants (ages 18-28) as the younger-group. The results indicated that elderly participants reaction time was delayed in the emotion category task compared to young participants. The second experiment used a cross-splicing method to explore how aging affects the recognition of emotional prosodies (e.g., angry or happy) as they unfold in time. To better understand the time course of the processing,event-related potentials (ERPs) obtained from 9 elderly (ages 50-60) and 10 younger participants (ages 19-24) in a probe verification task were analyzed.The results confirmed that categorization of emotional prosodies can be detected rapidly in early negativity. Most importantly, elderly participants were delayed in early positivity compared to younger participants, revealing an age-related defect during early emotion information transition into further processing.
