“…This pattern of results is similar to that seen in other experiments that have used the four-cue/two-task procedure. The magnitude of the task-switch effect is larger than in experiments with meaningful words as cues (Arrington & Logan, 2004b;Logan & Bundesen, 2003, 2004) but similar to those seen in other experiments that have also used arbitrary (nonword) cues (Logan & Bundesen, 2004;Mayr & Kliegl, 2003).…”

In the voluntary task switching procedure, subjects choose the task to perform on a series of bivalent stimuli, requiring top-down control of task switching. Experiments 1-3 contrasted voluntary task switching and explicit task cuing. Choice behavior showed small, inconsistent effects of external stimulus characteristics, supporting the assumption of top-down control of task choice. Switch costs were smaller when subjects chose to switch tasks than when instructed by an external cue. Experiments 4 -6 separated choice costs from switch costs. These findings support models of task switching that incorporate top-down processes in accounts of switch costs. The degree to which task switching procedures capture top-down versus bottom-up processes may depend on the extent of environmental support provided by the procedure.

“…Cue repetitions (M ϭ 632 ms) were much faster than task repetitions (M ϭ 778 ms) and task alternations (M ϭ 763 ms). Finding that task repetitions are slower than task alternations is unusual (Arrington & Logan, 2004;Logan & Bundesen, 2003Logan & Schneider, 2006a, 2006bMonsell & Mizon, 2006;Schneider & Logan, 2005. It suggests that subjects found it hard to repeat a vocal response when the cue changed from the previous trial.…”

“…Logan and Bundesen (2003) interpreted cue switch effects as cue encoding benefits that resulted from repeating the cue on cue-repetition trials. Other researchers have agreed with this interpretation (Arrington & Logan, 2004;Brass & von Cramon, 2004;Mayr & Kliegl, 2003;Monsell & Mizon, 2006). However, there is sharp disagreement over the interpretation of task switch effects.…”

“…Other researchers will need to account for these cue encoding effects when they develop explanations of reconfiguration and retrieval in the explicit task-cuing procedure. Whereas the methodology of the present experiments may have provided researchers with a way of isolating cue encoding effects empirically, our models provide them with a way of isolating them theoretically and estimating their duration (see Model 3 in Arrington &Bundesen, 2004; see also Schneider & Logan, 2007 We examined the RTI effects in the RT and accuracy data in the target responses, collapsing over RCI to obtain stable data. The means across subjects also appear in Table A1.…”

“…Some of these components are thought to be endogenous, occurring within the preparation interval, whereas others are thought to be exogenous, occurring only after the target appears. Other researchers have challenged the idea of reconfiguration, interpreting the same results as evidence for priming effects in the processes involved in encoding the cue, suggesting there is no endogenous or exogenous reconfiguration in the explicit task-cuing procedure (Arrington & Logan, 2004;Logan & Bundesen, 2003Schneider & Logan, 2005). The resolution of this controversy depends on researchers' ability to separate cue encoding benefits from task switch costs empirically.…”

Six experiments were conducted to separate cue encoding from target processing in explicitly cued task switching to determine whether task switch effects could be separated from cue encoding effects and to determine the nature of the representations produced by cue encoding. Subjects were required to respond to the cue, indicating which cue was presented (Experiments 1, 3a, and 4a) or which task was cued (Experiments 2, 3b, and 4b), before performing the cued task on the target. Cue encoding was successfully separated from target processing when the cue response indicated which task was cued but not when it indicated which cue was presented. Task switch effects were found when this separation was successful, suggesting that there are "true" task switch effects independent of cue encoding. Analysis of the conditions required for successful separation suggested that cue encoding results in a semantic categorical representation of the task to be performed rather than verbal or phonological representations of individual cues. Implications for the authors' past modeling of task-switching performance are discussed.
