    "subtitle": null,
    "abstract": "In task switching, the n-2 repetition cost (informally, the elevation\nin RT associated with performing a recently abandoned\ntask) is an indicator of residual task-set inhibition. One suggestion\nis that such inhibition is triggered by conflict between\ntask-set elements. We present a novel computational model\ninstantiating this proposal, by adding task-conflict monitoring\nunits to an existing, interactive activation model of task switching.\nThe model produces the empirical pattern, n-1 switch\ncosts and n-2 repetition costs, as an intrinsic property of its\narchitecture, but dependent on the inhibition of task demand\nunits by the conflict detection mechanism. In a further simulation,\nwe make predictions about n-2 repetition costs for asymmetric\ntasks, and show that one functional benefit of such a\nconflict-based, task inhibition mechanism is to facilitate topdown\ncontrol of tasks by automatically reducing cross-task interference",
