“…The cost of a change in the relevant perceptual attribute and the reduction in this cost with preparation has also been documented for spatial attention (Chiu & Yantis, 2009;Logan, 2005) and auditory attention (selecting the relevant voice in a dichoticlistening paradigm, Koch, Lawo, Fels, & Vorländer, 2011). However, an important characteristic of these studies, as well as Rushworth et al' (2005) ERP study and the Spatial attention in task-switching visual search investigations above, is that, unlike most task-switching studies, they required no change of categorization/decision criteria and S-R rules: these other key components of the task-set remained (largely) constant over trials.…”

“…This cue then indicates which task participants should perform in the upcoming trial. This kind of explicit cueing-procedure has been used in several studies to investigate auditory selective attention in a dichotic listening paradigm , 2015Koch, Lawo, Fels, & Vorländer, 2011;, 2015Lawo, Fels, Oberem, & Koch, 2014). In the dichotic listening paradigm, two different auditory stimuli or auditory streams are presented simultaneously, one to each ear.…”

“…In one study, Koch and collaborators applied a special case of auditory task switching in which the main focus was on the attentional demands of the task. Participants had to classify one of two dichotically presented number words: one spoken by a female voice and the other one spoken by a male voice (Koch et al, 2011). A visual cue that was presented before the spoken number words informed participants which speaker they had to attend to.…”

The current study focuses on auditory task switching, more precisely on switching attention between different temporal patterns of the same auditory stimulus. Tone sequences consisting of nine different pitch tones were presented aurally. Three repetitive short 3-tone patterns (local focus) were combined to a long pattern (global focus), and each could be either rising or falling, resulting in congruent or incongruent combinations. Participants were informed by a cue if they had to attend to the short or to the long pattern, and they indicated if the target pattern was rising or falling by pressing one of two keys. In two experiments, we investigated cued switches between the two attentional foci. Switch costs in reaction times and errors were observed when switching from the long to the short pattern but not when switching from the short to the long pattern. These asymmetric switch costs were reduced when participants had more time to prepare for the switch in a condition with a prolonged cue-stimulus interval. In addition, participants made more errors when global and local patterns did not correspond to each other (i.e., in incongruent trials) when attending to either of the patterns, but this congruency effect was not modulated by preparation time. The data suggest that the mechanisms of task goal prioritizing, as indicated by the asymmetric attention switch costs, are dissociable from those underlying stimulus selection, as indicated by the congruency effects.

“…The auditory number word was presented binaurally. The auditory number words were recorded in cooperation with the Institute of Technical Acoustics at RWTH Aachen University (see Koch, Lawo, Fels, & Vorländer, 2011). In the case of an erroneous response or response omission (and thus RT > 1, 500 ms), the German word for Berror^appeared centrally on the screen (Fehler; Courier, 20 pixels, white).…”

Shifts in target modality cause attentional reset: Evidence from sequential modulation of crossmodal congruency effects

et al. 2016

Reduced congruency effects after a preceding incongruent trial suggest a conflict-monitoring process, which reactively triggers the recruitment of attentional control in subsequent trials. In the present study, we assessed this sequential modulation of crossmodal congruency effects separately in two different tasks. Participants performed a location judgment task and a numerical judgment task in a block-wise fashion in a modality-switching paradigm. Stimuli were presented simultaneously in two modalities and were either congruent or incongruent (e.g., left visual object, right sound) with each other. The target modality was indicated by a cue, so that the target modalities either repeated or switched in successive trials. For both tasks, the results indicated reduced congruency effects after an incongruent trial only for modality repetitions, but not for switches. This finding suggests that modality switches induce a shift in episodic context, which in turn leads to an attentional reset. This reset eliminates the sequential modulation of congruency effects.Keywords Conflict adaptation . Attentional state . Attentional reset . Modality switching Conflicts arise at many processing levels throughout perception and action, influencing the efficiency of our actions. A predominant idea of how our cognitive system deals with such conflicts refers to the existence of a conflict-monitoring system (Botvinick, Braver, Barch, Carter, & Cohen, 2001). Whenever conflict is detected and evaluated by this system, reactively adapted mechanisms of cognitive control increase processing selectivity (i.e., selective attention) so that conflict is reduced in subsequent processing episodes. For example, attentional biasing of task-relevant aspects is strengthened and task-irrelevant aspects have less influence, resulting in improved performance (Egner, 2007).Conflicts can be induced experimentally by providing incongruent stimulus information. For example, in the Stroop task (Stroop, 1935), participants are supposed to indicate the font color of written color words. In congruent trials, the word Bred^is also displayed in red, and Bred^is the correct answer, whereas in incongruent trials, the word Bred^might be displayed in blue (with Bblue^as the correct answer). Here, conflict arises between the automatically read color word and the to-be-named font color. Performance is usually better in congruent (no-conflict) than in incongruent (conflict) trials, termed the congruency effect.
