Limits on introspection: Distorted subjective time during the dual-task bottleneck: Research article

Which cognitive processes are accessible to conscious report? To study the limits of conscious reportability, we designed a novel method of quantified introspection, in which subjects were asked, after each trial of a standard cognitive task, to estimate the time spent completing the task. We then a...

To study the limits of conscious reportability, we designed a novel method of quantified introspection, in which subjects were asked, after each trial of a standard cognitive task, to estimate the time spent completing the task. We then applied classical mental-chronometry techniques, such as the additive-factors method, to analyze these introspective estimates of response time. We demonstrate that introspective response time can be a sensitive measure, tightly correlated with objective response time in a single-task context. In a psychological-refractory- period task, however, the objective processing delay resulting from interference by a second concurrent task is totally absent from introspective estimates. These results suggest that introspective estimates of time spent on a task tightly correlate with the period of availability of central processing resources. © Copyright © 2008 Association for Psychological Science. 2008 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_09567976_v19_n11_p1110_Corallo http://hdl.handle.net/20.500.12110/paper_09567976_v19_n11_p1110_Corallo
