Identification of an Age Maturity in Time Discrimination Abilities

Résumé

The aim of this study was to identify the age at which parameters of timing performance in a temporal bisection task converge on an adult-like stable level. Participants in the three- to 20-year-old range were tested using a temporal bisection task with sub-second and supra-second durations. The data were divided into two samples. In the first sample, all participants were integrated into the analysis regardless of their success. In the second sample, only performers were inserted. The point of subjective equality (PSE) and the Weber Ratio (WR) were analyzed for each participant in each sample. By fitting a mathematical model to these parameters as a function of age, we showed that the PSE did not reach stability for the long durations due to a great inter-individual difference in the bisection point (BP) at these temporal values, while it reached a stable level for short durations in both samples. Yet, the stability points associated with the short duration BPs were reached in both samples. Interestingly, the stabilization points on WR converge earlier for the sample associated with the performers compared to the sample with no preselection. Nonetheless, time sensitivity (WR) shows a similar pattern through the two samples as adult-like performance appeared at an earlier age for short durations. The more gradual change in temporal performance for the long durations was explained by the processing of these durations, that requires attention and working memory capacities, which increase with age.
