Cognitive control: Preparation of task switching components
2012, Brain ResearchCitation Excerpt :This position has been handled formally by assuming the presence of control modules, for example change-detection (Brown et al., 2007) or input-biasing modules (Meiran et al., 2008), or controlled processing stages (e.g., Prepare-switch production, Sohn and Anderson, 2001) that act primarily on switch trials. Opponents of the switch-specific configuration account argue that shift-cost is an emergent property of a general configuration process that occurs on both repeat and shift trials (Altmann, 2003, 2004; Altmann and Gray, 2008; Logan and Bundesen, 2003, 2004). For example, Altmann and Gray (2008) propose that a type of semantic retrieval occurs on every trial, which is faster for repeat than switch trials due to the priming of relevant task representations.
The time course of the asymmetrical " local" switch cost: Evidence from event-related potentials
2011, Biological PsychologyCitation Excerpt :We paid special attention to those cognitive processes that can be engaged before the target is presented (at cue onset) and to those which are only present at target onset. The “local switch cost” or “behavioral switch cost” refers to the longer reaction times for targets involving a task change as compared to targets for which no task change is required (e.g., Meiran, 1996; Altmann, 2002; Rushworth et al., 2002; Altmann, 2003; Monsell, 2003). For example, when asked to classify target cards according to their color or their form (cf. Fig. 1), participants are slower when they have to switch to the other task rule than when they have to repeat the same task rule that they were using for the previous targets (Milner, 1963; Rubinstein et al., 2001; Barcelo, 2003; Barcelo et al., 2007).
ERPs dissociate the effects of switching task sets and task cues
2006, Brain ResearchCitation Excerpt :In cued task-switching paradigms, changes in RT switch cost and switch-related positivity with increasing cue–stimulus interval appear to provide a useful measure of cognitive control processes involved in task set reconfiguration. Recently, the contention that task-switching paradigms index cognitive control processes has been questioned (e.g., Logan, 2003; Altmann, 2003). It is argued that the RT switch cost found with cued task-switching paradigms does not necessarily reflect the cost of task set reconfiguration occurring as a result of the need to change task set.
