“…If more than one object is attended, multiple action plans are generated (Cisek & Kalaska, 2005), and the actual movement may represent a mixture between these action plans if there was not sufficient time to inhibit the movement plans to the wrong locations. With little time to inhibit conflicting movement plans, the final response represents a mixture between a response to the target and a response to the distractor, which is what was observed in the present and in previous studies (Buetti & Kerzel, 2009;Scherbaum, Dshemuchadse, Fischer, & Goschke, 2010;Welsh, 2011;Welsh & Elliott, 2004).…”

Reaction times in a visual search task increase when an irrelevant but salient stimulus is presented. Recently, the hypothesis that the increase in reaction times was due to attentional capture by the salient distractor has been disputed. We devised a task in which a search display was shown after observers had initiated a reaching movement toward a touch screen. In a display of vertical bars, observers had to touch the oblique target while ignoring a salient color singleton. Because the hand was moving when the display appeared, reach trajectories revealed the current selection for action. We observed that salient but irrelevant stimuli changed the reach trajectory at the same time as the target was selected, about 270 ms after movement onset. The change in direction was corrected after another 160 ms. In a second experiment, we compared manual selection of color and orientation targets and observed that selection occurred earlier for color than for orientation targets. Salient stimuli support faster selection than do less salient stimuli. Under the assumption that attentional selection for action and perception are based on a common mechanism, our results suggest that attention is indeed captured by salient stimuli.

“…Importantly, though, this apparent asymmetry arises from (mirror-)symmetrical adaptations to both preceding compatible and preceding incompatible trials, affecting the visuo-motor system on both compatible and incompatible trials. Furthermore, the model is consistent with the finding that context adaptation affects motor performance during, not prior to, response execution (Scherbaum et al, 2010).…”

Theories of cognitive control generally assume that perceived conflict acts as a signal to engage inhibitory mechanisms that suppress subsequent conflicting information. Crucially, an absence of conflict is not regarded as being a relevant signal for cognitive control. Using a Cueing, a Priming, and a Simon task, we provide evidence that conflict does not have this unique signal status: Encountering a conflict does not lead to behavioral adjustments on subsequent conflict trials, whereas encountering a non-conflict trial does lead to behavioral adjustments on subsequent nonconflict trials. We propose that this apparent role-reversal can be explained by a mechanism that responds to both the presence and the absence of conflict, down-regulating the visuo-motor system following conflict, and up-regulating it following non-conflict.

“…It should be noted, however, that within one computational framework (Dipisapia & Braver, 2006), the CSE might be considered a reactively triggered, short-term increase in proactive control (see Dipisapia & Braver, 2006;Braver et al, 2007;but see Duthoo & Notebaert, 2012;Scherbaum, Dshemuchadse, Fischer & Goschke, 2010).…”

Reactive and Proactive Control Adjustments under Increased Depressive Symptoms: Insights from the Classic and Emotional-Face Stroop Task

The current research investigated differences in reactive and proactive cognitive control as a function of depressive symptomatology. Three participant groups with varying symptom levels (Beck Depression Inventory–II, BDI–II score) completed both the classic and an emotional-face Stroop task separately under speed and accuracy instructions. All groups made equivalent speed–accuracy trade-offs independent of task, suggesting that proactive adjustments are unaffected by depressive symptoms. Additionally, groups made equivalent reactive control adjustments (Stroop effects, congruency sequence effects) in the classic Stroop task, suggesting that these reactive control adjustments are spared across a wide range of BDI–II scorers. In contrast, the high BDI–II group displayed a selective impairment in the resolution of conflict in the emotional-face Stroop task. Thus, while proactive control and many aspects of reactive control were unaffected by the level of depressive symptoms, specific impairments occurred when current task demands required the trial-to-trial regulation of emotional processing.
