How a co-actor's (Un-) reliability modulates goal selection in a novel joint goal-setting paradigm.

Sociomotor theory - an extension of ideomotor theory - suggests that actions can also be represented in terms of the effects they elicit from others. But what if those others violate one's action effect anticipations? Here, we introduce a novel joint goal-setting paradigm to investigate effects of co-actors' occasional and overall unreliability on an individual's goal selection. In a first step, the participant moved a target halfway from the bottom center to the top left or right corner of the computer screen.

Binding of the feature in the auditory domain: S-R or S-S binding; or both?

Perceiving and reacting to multidimensional objects creates so-called event files via feature binding. Bogon, Thomaschke, and Dreisbach provided the first evidence for the integration of the feature into such event files. However, their paradigm did not allow for differentiation between stimulus-stimulus and stimulus-response binding.

Control in context: The theta rhythm provides evidence for reactive control but no evidence for proactive control.

A prime goal of psychological science is to understand how humans can flexibly adapt to rapidly changing contexts. The foundation of this cognitive flexibility rests on contextual adjustments of cognitive control, which can be tested using the list-wide proportion congruency effect (LWPC). Blocks with mostly incongruent (MI) trials show smaller conflict interference effects compared to blocks with mostly congruent (MC) trials.

Flexibility by association? No evidence for an influence of cue-transition associations on voluntary task switching.

Some situations require cognitive flexibility, whereas others call for cognitive stability. Recent theories posit lower-level associative learning processes as the basis of contextual control. The present study incorporates six experiments to investigate whether cognitive flexibility can be triggered by task-irrelevant color cues in the task-switching paradigm.

Binding time: Investigations on the integration of visual stimulus duration.

The perception of and reaction to objects creates bindings of (object) features and responses, also called event files. In this context, is a so far understudied feature. We conducted four experiments to investigate whether the duration of visual stimuli is also integrated into such event files.

The role of objective and introspective switch costs in voluntary task choice.

Human beings are cognitive misers. One facet of this effort avoidance is the reluctance to voluntarily switch tasks when repeating the same task is allowed. Yet participants voluntarily switch despite the resulting costs.

Using the theory of constructed emotion to inform the study of cognition-emotion interactions.

In this article I suggest how theories of emotion construction may inform the study of cognition-emotion interactions. To do so, I adopt the two main concepts core affect and emotions as categories: Core affect, one's current affective state, which is defined by the two dimensions pleasure and arousal, is an inherent part of any conscious experience. Specific emotions are understood as categories including highly diverse exemplars.

To switch or to repeat? Commonalities and differences in the electrophysiological correlates of preparation for voluntary and forced task choices.

When switching tasks in the laboratory, either the experimenter or the participant can decide which task comes next. So far, this kind of forced and voluntary task switching is usually investigated in isolation. However, in our everyday life, switching between different tasks and goals often depends both on current situational demands and on our intentions.

Keep flexible-Keep switching? Boundary conditions of the influence of forced task switching on voluntary task switching.

Frequent forced switching between tasks has been shown to reduce switch costs and increase voluntary switch rates. So far, however, the boundary conditions of the influence of forced task switching on voluntary task switching are unknown. Thus, the present study was aimed to test different aspects of generalizability (across items, tasks, and time) of switching-induced flexibility established in forced-choice trials on voluntary switching in free-choice trials.

Investigating anticipatory processes during sequentially changing reward prospect: An ERP study.

Performance-contingent reward prospect modulates the stability-flexibility balance in voluntary task switching. High reward prospect typically increases stability, indicated by a low voluntary switch rate (VSR). But this effect depends on the immediate reward history: Only when a high reward repeats (reward remains high), stability is increased.

Conflict interference in an insect.

Response conflicts occur when the correct goal-congruent response is weaker than an alternative but incorrect response. To overcome response conflicts, the stronger response has to be inhibited, making the study of response conflicts an important research topic in higher order cognition. Response conflicts often result in conflict interference-an increase in error rates and response times.

The role of objective and subjective effort costs in voluntary task choice.

Human beings tend to avoid effort, if a less effortful option is equally rewarding. However, and in sharp contrast to this claim, we repeatedly found that (a subset of) participants deliberately choose the more difficult of two tasks in a voluntary task switching (VTS) paradigm even though avoidance of the difficult task was allowed (Jurczyk et al., Motivation Science 5:295-313, 2019).

Learning the Abstract General Task Structure in a Rapidly Changing Task Content.

The ability to learn abstract generalized structures of tasks is crucial for humans to adapt to changing environments and novel tasks. In a series of five experiments, we investigated this ability using a Rapid Instructed Task Learning paradigm (RITL) comprising short miniblocks, each involving two novel stimulus-response rules. Each miniblock included (a) instructions for the novel stimulus-response rules, (b) a NEXT phase involving a constant (familiar) intervening task (0-5 trials), (c) execution of the newly instructed rules (2 trials).

How Sequentially Changing Reward Prospect Modulates Meta-control: Increasing Reward Prospect Promotes Cognitive Flexibility.

Meta-control is necessary to regulate the balance between cognitive stability and flexibility. Evidence from (voluntary) task switching studies suggests performance-contingent reward as one modulating factor. Depending on the immediate reward history, reward prospect seems to promote either cognitive stability or flexibility: Increasing reward prospect reduced switch costs and increased the voluntary switch rate, suggesting increased cognitive flexibility.

Challenging voices: Mixed evidence for context-specific control adjustments in the auditory domain.

The flexible adjustment to changing demands is an astonishing human ability. One related phenomenon is the context-specific proportion congruency (CSPC) effect. Regarding response conflict, the CSPC refers to reduced response interference in contexts with a high conflict proportion as opposed to contexts with a low conflict proportion.

Enhancing task-demands disrupts learning but enhances transfer gains in short-term task-switching training.

Content variability was previously suggested to promote stronger learning effects in cognitive training whereas less variability incurred transfer costs (Sabah et al. Psychological Research, https://doi.org/10.

How sequential changes in reward expectation modulate cognitive control: Pupillometry as a tool to monitor dynamic changes in reward expectation.

Much evidence suggests that positive affect associated with performance-contingent reward modulates cognitive flexibility and stability. For example, in voluntary task switching, it has been shown that unchanged high reward promotes cognitive stability whereas increases or decreases in reward prospect as well as unchanged low reward promote cognitive flexibility (higher voluntary switch rate, VSR). Pupil diameter has been shown to respond to reward prospect, to task switching manipulations, and more generally to effort in cognitive control tasks and thus appears to be the ideal tool to learn more about the processes underlying these reward-modulated decisions.

Prospect of performance-contingent reward distorts the action relevance of predictive context information.

There is much evidence showing that the prospect of performance-contingent reward increases the usage of cuing information and cognitive stability. In a recent study, we showed that participants under reward conditions even continued using cues even when they were no longer predictive of the required response rule, even at the expense of higher errors feedback. In the present study, we aimed to investigate the mechanism underlying this maladaptive perseveration.

It's more than just conflict: The functional role of congruency in the sequential control adaptation.

According to the conflict monitoring theory (CMT), one of the most prominent theories of cognitive control, the exertion of cognitive control is triggered by the detection of conflicting response tendencies in the anterior cingulate cortex (ACC). Recent research has challenged this emphasis of response conflicts and has debated whether in addition to shielding after incongruent trials the relaxation after congruent trials also contributes to the sequential adaptation of control. To investigate the functionality of facilitative congruent trials in sequential adaptation of control, we conducted two experiments using a visual (Experiment 1) and an auditory (Experiment 2, preregistered) Simon task with stimuli presented laterally to the left or right (creating response congruent and incongruent trials) or without any particular spatial information (creating neutral trials).

Increasing reward prospect promotes cognitive flexibility: Direct evidence from voluntary task switching with double registration.

Recent research has suggested that sequential changes in the prospect of performance-contingent rewards may influence the balance between cognitive flexibility and stability: whereas constant high reward prospect seems to promote cognitive stability, increasing reward prospect has been shown to promote flexible behaviour in voluntary task-switching paradigms. Previous studies, however, confounded cognitive flexibility regarding voluntary task choices with control processes during task execution. We present five experiments to dissociate these two processes by means of a double registration procedure, in which task choice is registered prior to task execution.

Unexpected conflict signals loom larger in a positive context: Evidence from context specific control adjustments.

One prominent feature of adaptive cognition in humans is the ability to flexibly adjust to changing task demands. In this respect, context-specific proportion congruency (CSPC) effects describe the phenomenon that participants learn to adapt to contexts of frequently occurring conflicts even when the upcoming context cannot be anticipated. Here, we aim to provide evidence that such CSPC effects strongly depend on the affective valence of the context.

Shielding and relaxation in multitasking: Prospect of reward counteracts relaxation of task shielding in multitasking.

Performing two similar tasks at the same time requires the shielding of the prioritized Task 1 from interference of additional Task 2 processing (between-task interference). In the present study we tested how motivational factors such as prospect of reward might drive shifts between increased proactive control, enabling task shielding, and reduced proactive control resulting in relaxed task shielding. In Experiment 1 an instruction-induced prioritization of Task 1 over Task 2 resulted in initially reduced between-task interference.
