Action naming in French: Normative data and response latencies for 134 video stimuli

In spite of the inherently dynamic nature of actions, most psycholinguistic studies investigating action naming have relied on static images. To address this gap for French, we present a new database comprising 134 action videos. For each video, we developed five key psycholinguistic variables: Name agreement (NA), H-statistic, naming latency, uniqueness naming point (i.e., the moment in the video when the action becomes unmistakably identifiable) and adjusted naming latency. All variables are provided both for the overall sample and separately for adults under 50 years and those aged 50 and above. We then examined the influence of these variables on response latencies collected from 394 French-speaking participants. NA, the H-statistic and instrumentality significantly predicted response latencies. The video-based action naming database is freely available to clinicians and researchers. This study provides a new resource to explore action naming in both clinical and research contexts.
