Article
The experience of agency refers to the phenomenal experience of being the causal source of one's own actions, and through them, the course of events in the outside world. This experience is crucial for the production of adaptive actions, and for the adequate communication of felt action control to peers. The present study examines the possibility t...

Background. Depression has been associated with alterations in decision making and reinforcement learning, as well as with biases in metacognition, such as low confidence. However, interactions between these aspects of cognition remain under-investigated. Research in healthy participants has shown that difficulties during decision making can reduce...
Article
Living in complex social structures, humans have evolved a unique aptitude for mentalizing: trying to understand and predict the behaviour of others. To date, little is known about how mentalizing interacts with other cognitive processes. “Sense of agency” refers to the feeling of control over the outcomes of one's actions, providing a precursor of...
Article
Full-text available
Value-based decision-making involves trading off the cost associated with an action against its expected reward. Research has shown that both physical and mental effort constitute such subjective costs, biasing choices away from effortful actions, and discounting the value of obtained rewards. Facing conflicts between competing action alternatives...

Living in complex social structures, humans have evolved a unique aptitude for mentalizing. On one view, mentalizing has shaped neurocognitive evolution, yet, little is known about how mentalizing interacts with other cognitive processes. For social animals, the actions of one individual often impact others. “Sense of agency” refers to the feeling...

Adaptive behaviour requires the continued monitoring of action and its outcomes, to detect conflicts and correct behaviour accordingly. Conflict is considered aversive, and is typically avoided: people may choose easier tasks, or be biased by external suggestions. Conflict has also been shown to reduce the perceived control over action outcomes, an...

Full-text available
Social contexts substantially influence individual behavior, but little is known about how they affect cognitive processes related to voluntary action. Previously, it has been shown that social context reduces participants’ sense of agency over the outcomes of their actions and outcome monitoring. In this fMRI study on human volunteers, we investig...

Sense of agency (SoA) refers to the experience of voluntary control over one’s own actions, and, through them, over events in the outside world. Recent accounts suggest that SoA involves an integration of various cues. These include prospective cues, for example, related to the fluency of action selection, and retrospective cues, linked to outcome...

How do we know how much control we have over our environment? The sense of agency refers to the feeling that we are in control of our actions, and that, through them, we can control our external environment. Thus, agency clearly involves matching intentions, actions, and outcomes. The present studies investigated the possibility that processes of a...
Article
Full-text available
Sense of agency (SoA) refers to the feeling that we are in control of our actions and, through them, of events in the outside world. One influential view claims that the SoA depends on retrospectively matching the expected and actual outcomes of action. However, recent studies have revealed an additional, prospective component to SoA, driven by act...
Article
Full-text available
Diffusion of responsibility across agents has been proposed to underlie decreased helping and increased aggression in group behaviour. However, few studies have directly investigated effects of the presence of other people on how we experience the consequences of our actions. This EEG study investigated whether diffusion of responsibility simply re...

Sense of agency (SoA) involves a complex integration of various cues. These include prospective, related to the fluency of action selection, and retrospective, linked to outcome monitoring. It remains unclear whether these cues may have independent effects on SoA, and, in particular, how their relative contributions may change during instrumental l...
Conference Paper
The sense of agency (SoA) refers to the sense of being in control of one’s actions and, through them, of events in the external world. Much research has focused on how we link our actions to their outcomes. However, the contribution to SoA of processes linking our intentions to our actions has received little attention. The present research focused...
Article
Full-text available
The sense of agency refers to the feeling that we are in control of our actions and, through them, of events in the outside world. Much research has focused on the importance of retrospectively matching predicted and actual action outcomes for a strong sense of agency. Yet, recent studies have revealed that a metacognitive signal about the fluency...
Conference Paper
Full-text available
The sense of agency refers to the feeling that we are in control of our own actions and, through them, of events in the outside world. Many studies have shown the importance of a retrospective comparison between the expected and actual consequences of our actions. When there is a mismatch, and something that we did not expect happens, our sense of...
Article
Full-text available
Sense of agency refers to the feeling of controlling an external event through one's own action. On one influential view, agency depends on how predictable the consequences of one's action are, getting stronger as the match between predicted and actual effect of an action gets closer. Thus, sense of agency arises when external events that follow ou...
Article
Full-text available
The sense of control over the consequences of one's actions depends on predictions about these consequences. According to an influential computational model, consistency between predicted and observed action consequences attenuates perceived stimulus intensity, which might provide a marker of agentic control. An important assumption of this model i...
Article
Full-text available
Sense of agency (SoA) refers to the feeling that we are in control of our own actions and, through them, events in the outside world. SoA depends partly on retrospectively matching outcomes to expectations, and partly on prospective processes occurring prior to action, notably action selection. To assess the relative contribution of these processes...
