Initial evidence has indeed pointed towards a stronger recruitment of capacity-limited monitoring processes in dishonest than honest responding, conceivably resulting from the necessity to overcome automatic tendencies to respond honestly. Previous results suggested monitoring to be confined to response execution, however, whereas the current study goes beyond these findings by specifically probing for post-execution monitoring. Participants responded (dis)honestly to simple yes/no questions in a first task and switched to an unrelated second task after a response-stimulus interval of 0 ms or 1000 ms. Dishonest responses did not only prolong response times in Task 1, but also in Task 2 with a short response-stimulus interval. These findings support the assumption that increased monitoring for dishonest responses extends beyond mere response execution, a mechanism that is possibly tuned to assess the successful completion of a dishonest act.}, language = {en} } @article{KirschKunde2022, author = {Kirsch, Wladimir and Kunde, Wilfried}, title = {Perceptual changes after learning of an arbitrary mapping between vision and hand movements}, series = {Scientific Reports}, volume = {12}, journal = {Scientific Reports}, number = {1}, doi = {10.1038/s41598-022-15579-8}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-301074}, year = {2022}, abstract = {The present study examined the perceptual consequences of learning arbitrary mappings between visual stimuli and hand movements. Participants moved a small cursor with their unseen hand twice to a large visual target object and then judged either the relative distance of the hand movements (Exp.1), or the relative number of dots that appeared in the two consecutive target objects (Exp.2) using a two-alternative forced choice method. During a learning phase, the numbers of dots that appeared in the target object were correlated with the hand movement distance. In Exp.1, we observed that after the participants were trained to expect many dots with larger hand movements, they judged movements made to targets with many dots as being longer than the same movements made to targets with few dots. In Exp.2, another group of participants who received the same training judged the same number of dots as smaller when larger rather than smaller hand movements were executed. When many dots were paired with smaller hand movements during the learning phase of both experiments, no significant changes in the perception of movements and of visual stimuli were observed. These results suggest that changes in the perception of body states and of external objects can arise when certain body characteristics co-occur with certain characteristics of the environment. They also indicate that the (dis)integration of multimodal perceptual signals depends not only on the physical or statistical relation between these signals, but on which signal is currently attended.}, language = {en} } @article{NeszmelyiWellerKundeetal.2022, author = {Neszm{\´e}lyi, Bence and Weller, Lisa and Kunde, Wilfried and Pfister, Roland}, title = {Social action effects: representing predicted partner responses in social interactions}, series = {Frontiers in Human Neuroscience}, volume = {16}, journal = {Frontiers in Human Neuroscience}, issn = {1662-5161}, doi = {10.3389/fnhum.2022.837495}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-276609}, year = {2022}, abstract = {The sociomotor framework outlines a possible role of social action effects on human action control, suggesting that anticipated partner reactions are a major cue to represent, select, and initiate own body movements. Here, we review studies that elucidate the actual content of social action representations and that explore factors that can distinguish action control processes involving social and inanimate action effects. Specifically, we address two hypotheses on how the social context can influence effect-based action control: first, by providing unique social features such as body-related, anatomical codes, and second, by orienting attention towards any relevant feature dimensions of the action effects. The reviewed empirical work presents a surprisingly mixed picture: while there is indirect evidence for both accounts, previous studies that directly addressed the anatomical account showed no signs of the involvement of genuinely social features in sociomotor action control. Furthermore, several studies show evidence against the differentiation of social and non-social action effect processing, portraying sociomotor action representations as remarkably non-social. A focus on enhancing the social experience in future studies should, therefore, complement the current database to establish whether such settings give rise to the hypothesized influence of social context.}, language = {en} } @article{KirschKundeHerbort2021, author = {Kirsch, Wladimir and Kunde, Wilfried and Herbort, Oliver}, title = {Impact of proprioception on the perceived size and distance of external objects in a virtual action task}, series = {Psychonomic Bulletin \& Review}, volume = {28}, journal = {Psychonomic Bulletin \& Review}, number = {4}, issn = {1531-5320}, doi = {10.3758/s13423-021-01915-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-273235}, pages = {1191-1201}, year = {2021}, abstract = {Previous research has revealed changes in the perception of objects due to changes of object-oriented actions.

A multisensory approach to temporal binding construes actions and effects as individual sensory signals, which are each perceived with a specific temporal precision. When they are integrated into one multimodal event, like an action-effect chain, the extent to which they affect this event's perception depends on their relative reliability. We test whether this assumption holds true in a temporal binding task by manipulating certainty of actions and effects. Two experiments suggest that a relatively uncertain sensory signal in such action-effect sequences is shifted more towards its counterpart than a relatively certain one. This was especially pronounced for temporal binding of the action towards its effect but could also be shown for effect binding. Other conceptual approaches to temporal binding cannot easily explain these results, and the study therefore adds to the growing body of evidence endorsing a multisensory approach to temporal binding.}, language = {en} } @article{KirschKitzmannKunde2021, author = {Kirsch, Wladimir and Kitzmann, Tim and Kunde, Wilfried}, title = {Action affects perception through modulation of attention}, series = {Attention, Perception \& Psychophysics}, volume = {83}, journal = {Attention, Perception \& Psychophysics}, number = {5}, issn = {1943-393X}, doi = {10.3758/s13414-021-02277-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-273176}, pages = {2320-2330}, year = {2021}, abstract = {The present study explored the origin of perceptual changes repeatedly observed in the context of actions.

For this purpose, we replaced the hitting task by conditions of focused and distributed attention and measured the perception of the former target stimulus.

Therefore, it comes naturally, that different surface structures evoke different visual impressions in the viewer even if the material underlying these surface structures is the same. This topic is especially virulent for manufacturing processes in which more than one stakeholder is involved, but where the final product needs to meet certain criteria. A common practice to address such slight but perceivable differences in the visual appearance of structured surfaces is that trained evaluators assess the samples and assign a pass or fail. However, this process is both time consuming and cost intensive. Thus, we conducted two studies to analyze the relationship between physical surface structure parameters and participants visual assessment of the samples. With the first experiment, we aimed at uncovering a relationship between physical roughness parameters and visual lightness perception while the second experiment was designed to test participants' discrimination sensitivity across the range of stimuli. Perceived lightness and the measured surface roughness were nonlinearly related to the surface structure. Additionally, we found a linear relationship between the engraving parameter and physical brightness. Surface structure was an ideal predictor for perceived lightness and participants discriminated equally well across the entire range of surface structures.}, language = {en} } @article{LiesnerHinzKunde2021, author = {Liesner, Marvin and Hinz, Nina-Alisa and Kunde, Wilfried}, title = {How Action Shapes Body Ownership Momentarily and Throughout the Lifespan}, series = {Frontiers in Human Neuroscience}, volume = {15}, journal = {Frontiers in Human Neuroscience}, issn = {1662-5161}, doi = {10.3389/fnhum.2021.697810}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-241869}, year = {2021}, abstract = {Objects which a human agent controls by efferent activities (such as real or virtual tools) can be perceived by the agent as belonging to his or her body. This suggests that what an agent counts as "body" is plastic, depending on what she or he controls. Yet there are possible limitations for such momentary plasticity. One of these limitations is that sensations stemming from the body (e.g., proprioception) and sensations stemming from objects outside the body (e.g., vision) are not integrated if they do not sufficiently "match". What "matches" and what does not is conceivably determined by long-term experience with the perceptual changes that body movements typically produce. Children have accumulated less sensorimotor experience than adults have. Consequently, they express higher flexibility to integrate body-internal and body-external signals, independent of their "match" as suggested by rubber hand illusion studies. However, children's motor performance in tool use is more affected by mismatching body-internal and body-external action effects than that of adults, possibly because of less developed means to overcome such mismatches. We review research on perception-action interactions, multisensory integration, and developmental psychology to build bridges between these research fields. By doing so, we account for the flexibility of the sense of body ownership for actively controlled events and its development through ontogeny. This gives us the opportunity to validate the suggested mechanisms for generating ownership by investigating their effects in still developing and incomplete stages in children. We suggest testable predictions for future studies investigating both body ownership and motor skills throughout the lifespan.}, language = {en} } @article{WirthFoersterKundeetal.2020, author = {Wirth, Robert and Foerster, Anna and Kunde, Wilfried and Pfister, Roland}, title = {Design choices: Empirical recommendations for designing two-dimensional finger-tracking experiments}, series = {Behavior Research Methods}, volume = {52}, journal = {Behavior Research Methods}, doi = {10.3758/s13428-020-01409-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-235569}, pages = {2394-2416}, year = {2020}, abstract = {The continuous tracking of mouse or finger movements has become an increasingly popular research method for investigating cognitive and motivational processes such as decision-making, action-planning, and executive functions.
