Examining binding effects on task switch costs and response-Repetition effects: Variations of the cue modality and stimulus modality in task switching
Attention Perception & Psychophysics, 2019Co-Authors: Sven R. M. Kandalowski, Julia C. Seibold, Stefanie Schuch, Iring KochAbstract:Typically, response-Repetition effects are obtained in task-switching experiments: In task Repetitions, performance is enhanced when the response, too, repeats (response-Repetition benefits), whereas in task switches, performance is impaired when the response repeats (response-Repetition costs). A previous study introduced cue modality switches in a cued task-switching paradigm with visual stimuli and obtained enhanced response-Repetition benefits when the cue modality repeated (Koch, Frings, & Schuch Psychological Research, 82 , 570–579, 2018 ). In the present study, we aimed to replicate this finding with auditory stimuli (Exp. 1 ), and further examined whether response-Repetition effects could be modulated by introducing stimulus modality switches (Exp. 2 ). We found clear evidence that the cue modality and stimulus modality affect task switch costs. The task switch costs were higher with a repeated cue modality or stimulus modality. However, cue modality switches or stimulus modality switches did not affect the response-Repetition effects. We suggest that response-Repetition effects are elicited by response-associated bindings, which are not necessarily affected by all episodic task features to the same extent. Our results are also in line with theoretical accounts that assume a hierarchical organization of task selection and response selection.

Response Repetitions in auditory task switching: The influence of spatial response distance and of the response-stimulus interval.
Acta Psychologica, 2019Co-Authors: Julia C. Seibold, Sophie Nolden, Kim-phuong L. Vu, Iring Koch, Robert W. Proctor, Stefanie SchuchAbstract:Abstract In task switching studies, response Repetition effects are typically obtained: When the task repeats, response Repetitions are faster than response switches (response Repetition benefit), but when the task switches, the opposite is found (response Repetition cost). Previously, it was found that spatial response distance [RD] affected the response Repetitions: separated response keys led to longer reaction times [RT] for response Repetitions (in both task Repetitions and task switches) than adjacent response keys. The goal of the present study was to replicate this RD effect in a modified setup with auditory stimuli (in Experiments 1 and 2). As we were interested in the temporal dynamics of the RD effect, we also introduced a block-wise manipulation of response-stimulus interval (RSI) in Experiment 2. RD modulated responding, replicating the results of a prior study that used visual stimuli, but only when the RSI was long. With short RSI, the RD effect was not obtained. At the same time, a long RSI led to more pronounced response Repetition effects in the error rates. These results imply that response inhibition from the previous trial, which is assumed to contribute to the response Repetition effect and to the modulation of responding by response distance, builds up over time.

Lag-sensitive Repetition suppression effects in the anterior parahippocampal gyrus.
Hippocampus, 2005Co-Authors: Craig J. Brozinsky, Andrew P. Yonelinas, Neal E. A. Kroll, Charan RanganathAbstract:Single-unit recording studies of monkeys have shown that neurons in perirhinal and entorhinal cortex exhibit activity reductions following stimulus Repetition, and some have suggested that these “Repetition suppression” effects may represent neural signals that support recognition memory. Critically, Repetition suppression effects are most pronounced at short intervals between stimulus Repetitions. Here, we used event-related functional magnetic resonance imaging (fMRI) to identify Repetition suppression effects in the human medial temporal lobe and determine whether these effects are sensitive to the length of the interval between Repetitions. Twenty-one participants were scanned while performing a continuous recognition memory task in which the interval between item Repetitions was parametrically varied from 2 to 32 intervening items. We found evidence of Repetition suppression in the anterior parahippocampal gyrus, but only when the Repetition interval was relatively short. Moreover, bilateral hippocampal regions showed lag-sensitive Repetition effects. Our results demonstrate that activity in the human medial temporal cortex, like that of monkeys, exhibits Repetition suppression effects that are sensitive to the length of the interval between Repetitions. © 2005 Wiley-Liss, Inc.

stimulus category and response Repetition effects in task switching an evaluation of four explanations
Journal of Experimental Psychology: Learning Memory and Cognition, 2014Co-Authors: Michel D DrueyAbstract:In many task-switch studies, task sequence and response sequence interact: Response Repetitions produce benefits when the task repeats but produce costs when the task switches. Four different theoretical frameworks have been proposed to explain these effects: a reconfiguration-based account, association-learning models, an episodic-retrieval account, and a priming and inhibition account. The main goal in the present study was to test the unique prediction of the priming and inhibition account that stimulus categories remain active from one trial to the next, thus counteracting the negative effects of response inhibition in task-Repetition trials. As testing this prediction required a somewhat untypical task-switch design, a second aim in the present study consisted in evaluating the generality of the alternative models. In the present experiments the task-switch paradigm was modified to include trials in which pure stimulus-category Repetitions could occur. Across 3 experiments, benefits were observed for stimulus-category Repetitions in task-switch trials, a prediction that conforms only to the priming and inhibition account and the reconfiguration account. However, the benefits in task-Repetition trials were consistently smaller than the benefits in task-switch trials. This effect is in line only with the predictions from the priming and inhibition account. Thus, the current results support the notion of stimulus-category priming and response inhibition as the 2 mechanisms causing the opposite response-Repetition effects in task-Repetition and task-switch trials.

Response execution, selection, or activation: What is sufficient for response-related Repetition effects under task shifting?
Psychological Research, 2006Co-Authors: Ronald Hübner, Michel D DrueyAbstract:Repetition effects are often helpful in revealing information about mental structures and processes. Usually, positive effects have been observed when the stimuli or responses are repeated. However, in task shift studies it has also been found that response Repetitions can produce negative effects if the task shifts. Although several mechanisms have been proposed to account for this interaction between task shifting and response Repetition, many details remain open. Therefore, a series of four experiments was conducted to answer two questions. First, are motor responses necessary to produce response-related Repetition effects, or is response activation sufficient? Second, does the risk of an accidental re-execution of the last response affect the Repetition costs? The results show that response activation alone can produce Repetition effects. Furthermore, the risk of accidental response re-execution largely modulates these effects.
