Timing and executive resources: dual-task interference patterns between temporal production and shifting, updating, and inhibition tasks.

Three dual-task experiments were designed to assess the contribution of executive cognitive functions to the perception of time. Each experiment combined a serial temporal production timing task with an executive task emphasizing either shifting, updating, or inhibition. The experiments uncovered evidence of bidirectional interference between the concurrent tasks, such that the executive tasks interfered with timing performance and the timing task interfered with executive performance.
