Action control costs in task selection: Agents avoid actions with incompatible movement and effect features.

When a movement triggers effects with incompatible features, conflict between action and effect features creates costs for action planning and initiation. We investigated whether such action control costs also factor into action choices in terms of the principle of least effort. Participants completed a reaction-time experiment, where they were instructed to perform left and right mouse swipes in response to directional cues presented on the screen. Participants could select between two action options on each trial: Depending on which part of the screen (upper or lower) the action was performed in, the swipe resulted in a visual stimulus moving in the same (compatible) or in the opposite (incompatible) direction as the mouse. Incompatible action-effect mappings did indeed incur action control costs. In accordance with effort avoidance, the proportion of compatible choices was significantly above chance level, suggesting that action selection and initiation costs factor into participants preferences. Interestingly, however, participants' choice tendencies were not predicted by the actual increase in action-initiation costs in the incompatible condition. This indicates that effort-related decisions are not simply based on monitoring performance in the actual task, but they are also influenced by preestablished notions of action-planning costs.

Task-relevance and change detection in action-effect binding.

Features of actions are bound to coincidentally occurring stimuli so that re-encountering a stimulus retrieves a previous action episode. One hallmark of the purported mechanism in binding/retrieval tasks is a reliable reaction time advantage for repeating a previous response if tone stimuli repeat rather than alternate across trials. Other measures than reaction times yielded surprisingly mixed results, however. This is particularly true for continuous response features like force or response duration. We therefore conducted two experiments to resolve this disconnect between different measures. Experiment 1 tested for a potentially inflated effect in reaction time data, whereas Experiment 2 took the converse approach of studying conditions that would elicit similarly strong effects on alternative measures. Our results show that confounds in terms of auditory change detection do not inflate reaction time differences, reinforcing an interpretation of these effects as reflecting binding and retrieval. Moreover, strong effects on alternative measures appeared if these features were rendered task-relevant and came with sufficient variability. These observations provide critical evidence for binding and retrieval accounts, especially by showing that these accounts extend from binary decisions to continuous features of an actual motor response.

Sticky tradition impedes selection of creative ideas.

Creativity is a driving force for human development and has fascinated scholars for centuries. Surprisingly little is known about the cognitive underpinnings of putting creative ideas into action, however. To shed light on this part of the creative process, we tracked how hand movements unfolded when choosing between either a traditional or a creative use of a given object. Participants could freely decide between both options (Experiment 1, N = 51 adults) or were prompted to select a specific use (Experiment 2, N = 51 adults). Temporal as well as spatial measures of action unfolding revealed behavior to be strongly biased toward traditional options when choosing an available, more creative option eventually. Creative behavior thus comprises two obstacles: not only coming up with new ideas, but also overcoming a lasting bias toward using old ones.

The relation between learning and stimulus-response binding.

Perception and action rely on integrating or binding different features of stimuli and responses. Such bindings are short-lived, but they can be retrieved for a limited amount of time if any of their features is reactivated. This is particularly true for stimulus-response bindings, allowing for flexible recycling of previous action plans. A relation to learning of stimulus-response associations suggests itself, and previous accounts have proposed binding as an initial step of forging associations in long-term memory. The evidence for this claim is surprisingly mixed, however. Here we propose a framework that explains previous failures to detect meaningful relations of binding and learning by highlighting the joint contribution of three variables: (a) decay, (b) the number of repetitions, and (c) the time elapsing between repetitions. Accounting for the interplay of these variables provides a promising blueprint for innovative experimental designs that bridge the gap between immediate bindings on the one hand and lasting associations in memory on the other hand.

Creative thinking does not promote dishonesty.

We assessed the relation of creativity and unethical behaviour by manipulating the thinking style of participants (N = 450 adults) and measuring the impact of this manipulation on the prevalence of dishonest behaviour. Participants performed one of three inducer tasks: the alternative uses task to promote divergent thinking, the remote associates task to promote convergent thinking, or a simple classification task for rule-based thinking. Before and after this manipulation, participants conducted the mind game as a straightforward measure of dishonesty. Dishonest behaviour increased from before to after the intervention, but we found no credible evidence that this increase differed between induced mindsets. Exploratory analyses did not support any relation of trait creativity and dishonesty either. We conclude that the influence of creative thinking on unethical behaviour seems to be more ambiguous than assumed in earlier research or might be restricted to specific populations or contexts.

Following Affirmative and Negated Rules.

Rules are often stated in a negated manner ("no trespassing") rather than in an affirmative manner ("stay in your lane"). Here, we build on classic research on negation processing and, using a finger-tracking design on a touchscreen, we show that following negated rather than affirmative rules is harder as indicated by multiple performance measures. Moreover, our results indicate that practice has a surprisingly limited effect on negated rules, which are implemented more quickly with training, but this effect comes at the expense of reduced efficiency. Only affirmative rules are thus put into action efficiently, highlighting the importance of tailoring how rules are communicated to the peculiarities of the human mind.

Headlines win elections: Mere exposure to fictitious news media alters voting behavior.

Repeatedly encountering a stimulus biases the observer's affective response and evaluation of the stimuli. Here we provide evidence for a causal link between mere exposure to fictitious news reports and subsequent voting behavior. In four pre-registered online experiments, participants browsed through newspaper webpages and were tacitly exposed to names of fictitious politicians. Exposure predicted voting behavior in a subsequent mock election, with a consistent preference for frequent over infrequent names, except when news items were decidedly negative. Follow-up analyses indicated that mere media presence fuels implicit personality theories regarding a candidate's vigor in political contexts. News outlets should therefore be mindful to cover political candidates as evenly as possible.

Binding and retrieval of temporal action features: Probing the precision level of feature representations in action planning.

The duration of action can be critical to accomplishing specific goals. Empirical findings and theoretical considerations suggest that different stages of action planning and execution require different specification levels of action features. It is assumed that at first only crude categorical features are integrated into action plans, which are then specified by subsequent sensorimotor processes during action execution based on situational conditions. In two experiments, we investigated if the integration of action duration into action plans indeed relies exclusively on categorical duration representations or also on continuous-metric representations. Participants responded to visual prime and probe stimuli with short and long key presses. The duration of the prime response was indicated by a previous response cue, and the duration of the probe response was indicated by the shape of the probe stimulus. Analyses of response durations revealed that for response category repetitions from prime to probe, the actual durations of the repeated responses were more similar for shape repetitions than for shape switches. This indicates that continuous temporal information is integrated into an action plan and subsequently retrieved by stimulus repetition. Our results suggest that action duration is integrated into the action plan in a relatively precise form at an early stage of action planning.

Sense of agency in social hierarchies.

Distributing complex actions across agents is commonplace in human society. The objective efficiency of joint actions comes with critical challenges for the sense of agency of individual agents, complicating an accurate formation of these agents' perceived control over actions and action outcomes. Here we report a new experimental paradigm to investigate sense of agency for supervisors and subordinates in hierarchical settings. Results indicate profound differences in the sense of agency between both roles, while also indicating additional contributions of such situational factors as degrees of freedom, action decision versus action execution, outcome valence, and veto options. We further observed a tight coupling of sense of agency and sense of responsibility, with only weak links to affective responses to the action outcome.

Action representations in prevention behavior: Evidence from motor execution.

Human actions sometimes aim at preventing an event from occurring. How these to-be-prevented events are represented, however, is poorly understood. Recent proposals in the literature point to a possible divide between effect-producing, operant actions, and effect-precluding, prevention actions, suggesting that the control of operant actions relies on codes of environment-related effects whereas prevention actions do not. Here we report two experiments on this issue, showing that spatial features (Experiment 1) as well as temporal features (Experiment 2) of to-be-prevented events influence actions in the same way as corresponding features of to-be-produced effects. This implies that selecting and executing prevention actions relies on anticipated environmental changes, comparable to operant actions.

What is left after an error? Towards a comprehensive account of goal-based binding and retrieval.

The cognitive system readily detects and corrects erroneous actions by establishing episodic bindings between representations of the acted upon stimuli and the intended correct response. If these stimuli are encountered again, they trigger the retrieval of the correct response. Thus, binding and retrieval efficiently pave the way for future success. The current study set out to define the role of the erroneous response itself and explicit feedback for the error during these processes of goal-based binding and retrieval. Two experiments showed robust and similar binding and retrieval effects with and without feedback and pointed towards sustained activation of the unbound, erroneous response. The third experiment confirmed that the erroneous response is more readily available than a neutral alternative. Together, the results demonstrate that episodic binding biases future actions toward success, guided primarily through internal feedback processes, while the erroneous response still leaves detectable traces in human action control.

Post-execution monitoring in dishonesty.

When telling a lie, humans might engage in stronger monitoring of their behavior than when telling the truth. 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.

Cognitive load promotes honesty.

In three experiments, we examined the cognitive underpinnings of self-serving dishonesty by manipulating cognitive load under different incentive structures. Participants could increase a financial bonus by misreporting outcomes of private die rolls without any risk of detection. At the same time, they had to remember letter strings of varying length. If honesty is the automatic response tendency and dishonesty is cognitively demanding, lying behavior should be less evident under high cognitive load. This hypothesis was supported by the outcome of two out of three experiments. We further manipulated whether all trials or only one random trial determined payoff to modulate reward adaptation over time (Experiment 2) and whether payoff was framed as a financial gain or loss (Experiment 3). The payoff scheme of one random or all trials did not affect lying behavior and, discordant to earlier research, facing losses instead of gains did not increase lying behavior. Finally, cognitive load and incentive frame interacted significantly, but contrary to our assumption gains increased lying under low cognitive load. While the impact of cognitive load on dishonesty appears to be comparably robust, motivational influences seem to be more elusive than commonly assumed in current theorizing.

Perception and action as viewed from the Theory of Event Coding: a multi-lab replication and effect size estimation of common experimental designs.

The Theory of Event Coding (TEC) has influenced research on action and perception across the past two decades. It integrates several seminal empirical phenomena and it has continued to stimulate novel experimental approaches on the representational foundations of action control and perceptual experience. Yet, many of the most notable results surrounding TEC originate from an era of psychological research that relied on rather small sample sizes as judged by today's standards. This state hampers future research aiming to build on previous phenomena. We, therefore, provide a multi-lab re-assessment of the following six classical observations: response-effect compatibility, action-induced blindness, response-effect learning, stimulus-response binding, code occupation, and short-term response-effect binding. Our major goal is to provide precise estimates of corresponding effect sizes to facilitate future scientific endeavors. These effect sizes turned out to be considerably smaller than in the original reports, thus allowing for informed decisions on how to address each phenomenon in future work. Of note, the most relevant results of the original observations were consistently obtained in the present experiments as well.

Binding and Retrieval of Response Durations: Subtle Evidence for Episodic Processing of Continuous Movement Features.

Re-encountering a stimulus retrieves nominally relevant, categorical response features related to previous action decisions in response to this stimulus. Whether binding and retrieval extend to nominally irrelevant, metric features relating to an actual body movement is unknown, however. In two experiments, we thus tested whether repeating target or distractor stimuli across trials retrieves the irrelevant duration of spatial responses to these stimuli. We found subtle indication of such retrieval by task-relevant target stimuli, suggesting that binding and retrieval also operate on metric features of a motor response. In contrast, there was no sign of binding and retrieval of metric features for distractor stimuli. We discuss these observations regarding the representation of action episodes during action-related decision making and during actual movement initiation and control.

Binding Error-Induced Control States.

Binding and retrieval of stimulus features, response features, and their attentional weighting tune cognitive processing to situational demands. The two mechanisms promote successful actions, especially in situations in which such actions depend on controlled processing. Here we explored binding and retrieval of attentional control states that follow from erroneous actions. By definition, such errors are characterized by insufficient cognitive control but at the same time, error detection has been shown to trigger corresponding adjustments to prevent future failures. We reanalyzed existing datasets and conducted a novel experiment to investigate whether error-induced control states become bound to task-relevant stimuli. Results point towards a binding and retrieval of error-induced control states; however, the effect appears to be less reliable than for binding and retrieval of specific stimulus and response features. We discuss potential implications and alternative interpretations in terms of a mediating impact of error-induced control.

Binding of Task-Irrelevant Action Features and Auditory Action Effects.

Discrete task-relevant features of an overt response, such as response location, are bound to, and retrieved by coincidentally occurring auditory stimuli. Here we studied whether continuous, task-irrelevant response features like force or response duration also become bound to, and retrieved by such stimuli. In two experiments we asked participants to carry out a pinch which produced a certain auditory effect in a prime part of each trial. In a subsequent probe part, tones served as imperative stimuli which either repeated or changed as compared to the effect tone in the prime. We conjectured that the repetition of tones should result in more similar responses in terms of force output and duration as compared to tone changes. Most parameters did not show notable indications for such similarity increases, including peak force or area under force curve, though the correlation between response durations in prime and probe was higher when tones repeated rather than changed from prime to probe. We discuss these results regarding perceptual discriminability and deployment of attention to different nominally task-irrelevant aspects of pinch responses.

Frankly, My Error, I Don't Give a Damn: Retrieval of Goal-Based but Not Coactivation-Based Bindings after Erroneous Responses.

Previous studies demonstrated binding and retrieval of stimuli and correct responses even for those episodes in which the actual response was wrong (goal-based binding and retrieval). In the current study, we tested whether binding based on a co-activation of stimuli and erroneous responses occurred simultaneously with goal-based binding, which could have been masked by a more efficient retrieval of goal-based bindings in previous studies. In a pre-registered experiment (n = 62), we employed a sequential prime-probe design with a three-choice colour categorisation task. Including three different responses in the task allowed us to conduct separate tests for stimulus-based episodic retrieval of either the correct response (goal-based) or of the actual erroneous response (coactivation-based) after committing an error. Replicating previous findings, our study provides support for goal-based binding of stimuli and correct responses after errors, while showing that there is no independent coactivation-based binding of the erroneous response itself.

Instant disembodiment of virtual body parts.

Evidence from multisensory body illusions suggests that body representations may be malleable, for instance, by embodying external objects. However, adjusting body representations to current task demands also implies that external objects become disembodied from the body representation if they are no longer required. In the current web-based study, we induced the embodiment of a two-dimensional (2D) virtual hand that could be controlled by active movements of a computer mouse or on a touchpad. Following initial embodiment, we probed for disembodiment by comparing two conditions: Participants either continued moving the virtual hand or they stopped moving and kept the hand still. Based on theoretical accounts that conceptualize body representations as a set of multisensory bindings, we expected gradual disembodiment of the virtual hand if the body representations are no longer updated through correlated visuomotor signals. In contrast to our prediction, the virtual hand was instantly disembodied as soon as participants stopped moving it. This result was replicated in two follow-up experiments. The observed instantaneous disembodiment might suggest that humans are sensitive to the rapid changes that characterize action and body in virtual environments, and hence adjust corresponding body representations particularly swiftly.

Never run a changing system: Action-effect contingency shapes prospective agency.

Human action control is highly sensitive to action-effect contingencies in the agent's environment. Here we show that the subjective sense of agency (SoA) contributes to this sensitivity as a subjective counterpart to instrumental action decisions. Participants (N = 556) experienced varying reward probabilities and were prompted to give summary evaluations of their SoA after a series of action-effect episodes. Results first revealed a quadratic relation of contingency and SoA, driven by a disproportionally strong impact of perfect action-effect contingencies. In addition to this strong situational determinant of SoA, we observed small but reliable interindividual differences as a function of gender, assertiveness, and neuroticism that applied especially at imperfect action-effect contingencies. Crucially, SoA not only reflected the reward structure of the environment but was also associated with the agent's future action decisions across situational and personal factors. These findings call for a paradigm shift in research on perceived agency, away from the retrospective assessment of single behavioral episodes and towards a prospective view that draws on statistical regularities of an agent's environment.
