How visual eccentricity shapes conflict via target and distractor processing in the Simon task
The visual Simon task is widely used to study action control in the presence of conflicting target and distractor information. However, it is unclear how one of the core parameters of this task, visual target eccentricity, affects conflict processing. Building on a quantitative dual-route model Diffusion Model for Conflict Tasks (DMC), we hypothesized that increased eccentricity alters the relative strength of target- and distractor-based activat…
When meaning doesn’t matter, but location does: The effect of stimulus-hand proximity on conflict processing in the auditory modality
Studies have shown that variations in stimulus-hand proximity alter conflict processing. Stimulus-response (S-R) conflict in visuo- and auditory Simon tasks increases when response hands are placed close (proximal) to the stimulus compared to when they are placed far (distal) from the stimulus. Conversely, a stimulus-stimulus (S-S) conflict in a classical visual Stroop paradigm was reduced in a proximal compared to a distal stimulus-hand conditio…
Level-1-visual perspective taking for human and robot avatars
Research on level 1 visual perspective taking (L1-VPT) has been debating whether L1-VPT is an implicit socially rooted or rather a non-social process. Using online versions of the Dot Perspective Task by Samson et al. ( Journal of Experimental Psychology: Human Perception and Performance, 36 (5), 1255–1266, 2010) we approached this question by comparing L1-VPT for robot vs. human avatars. In line with the assumption that visual perspective taking…
Order effects in stimulus discrimination challenge established models of comparative judgement: A meta-analytic review of the Type B effect
This paper provides a comprehensive review of the Type B effect (TBE), a phenomenon reflected in the observation that discrimination sensitivity varies with the order of stimuli in comparative judgment tasks, such as the two-alternative forced-choice (2AFC) paradigm. Specifically, when the difference threshold is lower (higher) with the constant standard preceding rather than following the variable comparison, one speaks of a negative (positive) …
The role of action inhibition for behavioral control in joint action
When two individuals share a task with a common goal, coordinating one’s own and the other’s actions is pivotal. Inhibition of one’s own actions when it is the other’s turn to act is assumed to play a crucial role in this process. For instance, in the joint Simon task, two individuals share a two-choice task such that one of them responds to one stimulus type and ignores the stimulus type to which the other responds. Because stimuli can either ap…
Action prediction modulates self–other integration in joint action
People often coordinate actions with others, requiring an adjustable amount of self–other integration between actor’s and co-actor’s actions. Previous research suggests that such self–other integration (indexed by the joint Simon effect) is enhanced by agent similarity of the co-actor (e.g., high in intentionality). In this study, we aimed to extend this line of research by testing whether experiencing agency over a co-actor’s actions (vicarious …
Metacontrol and joint action: How shared goals transfer from one task to another
In most of our daily activities and in team sports, we interact with other individuals and do not act in isolation. Using a social variant of the standard two-choice Simon task, this study aims to test if competitive/cooperative processing modes (i.e., metacontrol states) change the degree of bodily self-other integration between two persons in joint action. In addition, and more exploratory the study tested if this effect depends on a shared gro…
