The present study shows that the own name has the power to bias a person's actions unconsciously even in conditions that render any other name ineffective. Participants judged whether a letter string on the screen was a name or a non-word while this target stimulus was preceded by a masked prime stimulus. Crucially, the participant's own name was among these prime stimuli and facilitated reactions to following name targets whereas the name of another, yoked participant did not. Signal detection results confirmed that participants were not aware of any of the prime stimuli, including their own name. These results extend traditional findings on ''breakthrough'' phenomena of personally relevant stimuli to the domain of unconscious processing. Thus, the brain seems to possess adroit mechanisms to identify and process such stimuli even in the absence of conscious awareness.}, subject = {Psychologie}, language = {en} } @article{KlaffehnSellmannKirschetal.2021, author = {Klaffehn, Annika L. and Sellmann, Florian B. and Kirsch, Wladimir and Kunde, Wilfried and Pfister, Roland}, title = {Temporal binding as multisensory integration: Manipulating perceptual certainty of actions and their effects}, series = {Attention, Perception \& Psychophysics}, volume = {83}, journal = {Attention, Perception \& Psychophysics}, number = {8}, issn = {1943-393X}, doi = {10.3758/s13414-021-02314-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-273195}, pages = {3135-3145}, year = {2021}, abstract = {It has been proposed that statistical integration of multisensory cues may be a suitable framework to explain temporal binding, that is, the finding that causally related events such as an action and its effect are perceived to be shifted towards each other in time. 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{MockeWellerFringsetal.2020, author = {Mocke, Viola and Weller, Lisa and Frings, Christian and Rothermund, Klaus and Kunde, Wilfried}, title = {Task relevance determines binding of effect features in action planning}, series = {Attention, Perception, \& Psychophysics}, volume = {82}, journal = {Attention, Perception, \& Psychophysics}, issn = {1943-3921}, doi = {10.3758/s13414-020-02123-x}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-231906}, pages = {3811-3831}, year = {2020}, abstract = {Action planning can be construed as the temporary binding of features of perceptual action effects. While previous research demonstrated binding for task-relevant, body-related effect features, the role of task-irrelevant or environment-related effect features in action planning is less clear. Here, we studied whether task-relevance or body-relatedness determines feature binding in action planning. Participants planned an action A, but before executing it initiated an intermediate action B. Each action relied on a body-related effect feature (index vs. middle finger movement) and an environment-related effect feature (cursor movement towards vs. away from a reference object). In Experiments 1 and 2, both effects were task-relevant. Performance in action B suffered from partial feature overlap with action A compared to full feature repetition or alternation, which is in line with binding of both features while planning action A. Importantly, this cost disappeared when all features were available but only body-related features were task-relevant (Experiment 3). When only the environment-related effect of action A was known in advance, action B benefitted when it aimed at the same (vs. a different) environment-related effect (Experiment 4). Consequently, the present results support the idea that task relevance determines whether binding of body-related and environment-related effect features takes place while the pre-activation of environment-related features without binding them primes feature-overlapping actions.}, language = {en} } @article{LiesnerKunde2020, author = {Liesner, Marvin and Kunde, Wilfried}, title = {Suppression of mutually incompatible proprioceptive and visual action effects in tool use}, series = {PLoS One}, volume = {15}, journal = {PLoS One}, number = {11}, doi = {10.1371/journal.pone.0242327}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-231250}, year = {2020}, abstract = {Movements of a tool typically diverge from the movements of the hand manipulating that tool, such as when operating a pivotal lever where tool and hand move in opposite directions. Previous studies suggest that humans are often unaware of the position or movements of their effective body part (mostly the hand) in such situations. It has been suggested that this might be due to a "haptic neglect" of bodily sensations to decrease the interference of representations of body and tool movements. However, in principle this interference could also be decreased by neglecting sensations regarding the tool and focusing instead on body movements. While in most tool use situations the tool-related action effects are task-relevant and thus suppression of body-related rather than tool-related sensations is more beneficial for successful goal achievement, we manipulated this task-relevance in a controlled experiment. The results showed that visual, tool-related effect representations can be suppressed just as proprioceptive, body-related ones in situations where effect representations interfere, given that task-relevance of body-related effects is increased relative to tool-related ones.}, language = {en} } @article{LiesnerKirschPfisteretal.2020, author = {Liesner, Marvin and Kirsch, Wladimir and Pfister, Roland and Kunde, Wilfried}, title = {Spatial action-effect binding depends on type of action-effect transformation}, series = {Attention, Perception, \& Psychophysics}, volume = {82}, journal = {Attention, Perception, \& Psychophysics}, issn = {1943-3921}, doi = {10.3758/s13414-020-02013-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-232781}, pages = {2531-2543}, year = {2020}, abstract = {Spatial action-effect binding denotes the mutual attraction between the perceived position of an effector (e.g., one's own hand) and a distal object that is controlled by this effector. Such spatial binding can be construed as an implicit measure of object ownership, thus the belonging of a controlled object to the own body. The current study investigated how different transformations of hand movements (body-internal action component) into movements of a visual object (body-external action component) affect spatial action-effect binding, and thus implicit object ownership. In brief, participants had to bring a cursor on the computer screen into a predefined target position by moving their occluded hand on a tablet and had to estimate their final hand position. In Experiment 1, we found a significantly lower drift of the proprioceptive position of the hand towards the visual object when hand movements were transformed into laterally inverted cursor movements, rather than cursor movements in the same direction. Experiment 2 showed that this reduction reflected an elimination of spatial action-effect binding in the inverted condition. The results are discussed with respect to the prerequisites for an experience of ownership over artificial, noncorporeal objects. Our results show that predictability of an object movement alone is not a sufficient condition for ownership because, depending on the type of transformation, integration of the effector and a distal object can be fully abolished even under conditions of full controllability.}, 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{FoersterPfisterWirthetal.2023, author = {Foerster, Anna and Pfister, Roland and Wirth, Robert and Kunde, Wilfried}, title = {Post-execution monitoring in dishonesty}, series = {Psychological Research}, volume = {87}, journal = {Psychological Research}, number = {3}, doi = {10.1007/s00426-022-01691-x}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-324862}, pages = {845-861}, year = {2023}, abstract = {When telling a lie, humans might engage in stronger monitoring of their behavior than when telling the truth.

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.

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.

Therefore, we investigated the extent to which novices and skilled high-jump athletes are able to identify visually presented body postures of the high jump unconsciously. We also asked whether or not the manner of processing differs (qualitatively or quantitatively) between these groups as a function of their motor expertise. A priming experiment with not consciously perceivable stimuli was designed to determine whether subliminal priming of movement phases (same vs. different movement phases) or temporal order (i.e. natural vs. reversed movement order) affects target processing. Participants had to decide which phase of the high jump (approach vs. flight phase) a target photograph was taken from. We found a main effect of temporal order for skilled athletes, that is, faster reaction times for prime-target pairs that reflected the natural movement order as opposed to the reversed movement order. This result indicates that temporal-order information pertaining to the domain of expertise plays a critical role in athletes' perceptual capacities. For novices, data analyses revealed an interaction between temporal order and movement phases. That is, only the reversed movement order of flight-approach pictures increased processing time. Taken together, the results suggest that the structure of cognitive movement representation modulates unconscious processing of movement pictures and points to a functional role of motor representations in visual perception.}, language = {en} }
