Age-related changes in time discrimination: The involvement of inhibition, working memory and speed of processing

摘要: Background: Researchers have devoted much effort in trying to understand how and why our subjective experience of time changes across the adult life-span. The cognitive apparatus that supports timing is integrally entwined with those supporting other processes including working memory, inhibition speed processing. Methods: One-hundred-eighty adults ranged from 19 87 years old participated study. A discrimination task, two standard intervals (short standard = 500 ms; long standard = 1500 ms) was used. Moreover, N-back Stroop tasks were used assess Results: Data analysed a multilevel mixed model approach. Accounting for between-subject variability, we compared models order better fit using chi-square likelihood-ratio test, Akaike information criterion Bayesian criterion. Results showed significant interaction between age, interval, comparison interval Conclusion: Our study confirmed younger participants generally more accurate conditions than older ones; also performance depended indeed on intervals, but processing abilities age.
