Summary

This summary is machine-generated.

Vicarious sense of agency (SoA) emerges toward artificial agents when users perceive action effects, even without performing actions. This feeling relies on later cognitive processes, distinct from self-agency mechanisms.

Area Of Science

  • Cognitive Neuroscience
  • Human-Computer Interaction
  • Artificial Intelligence

Background

  • Sense of Agency (SoA) is the feeling of control over one's actions and their outcomes.
  • Vicarious SoA can extend to actions performed by artificial agents.
  • Understanding the minimal conditions for vicarious SoA is crucial for designing intuitive AI interactions.

Purpose Of The Study

  • To investigate the minimal conditions for developing vicarious SoA towards artificial agents.
  • To determine if vicarious SoA emerges solely from perceiving action effects, without motor execution.
  • To explore the role of expectancy and learned associations in vicarious SoA.

Main Methods

  • Two experiments utilizing the Intentional Binding (IB) task, a behavioral measure of SoA.
  • Experiment 1 (Solo): Participants judged self-generated tones.
  • Experiment 2: Participants judged tones produced by an artificial agent (computer-generated keypress) without motor action, measuring proximal and distal effects.
  • Electroencephalography (EEG) recorded neural activity, focusing on N1 and P2 components.

Main Results

  • The IB effect consistently emerged in both experiments, indicating SoA.
  • Vicarious SoA was established when participants had access to the proximal action effect, even without performing the action.
  • Neural analysis suggested self-agency relies partly on N1 (motor predictions), while vicarious agency involves later cognitive processes indexed by P2.

Conclusions

  • Perceiving action effects, particularly proximal ones, is sufficient for developing vicarious SoA towards artificial agents, even without motor involvement.
  • Individual and vicarious SoA, while behaviorally similar (IB effect), may involve distinct neural mechanisms.
  • Findings inform the design of AI systems that foster a sense of agency and control.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

The concept of nonconscious mimicry is not a new one. How often do you find yourself mimicking someone’s behavior or speech, or even beginning to like the same things that they do? Such actions relate to forming affiliation and fitting in within social situations. Here, this phenomenon will be explored from various aspects to understand how...

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor. 

Empathy is often confused with pity and sympathy, which are different reactions to the situation of someone else or...

Lazarus's Cognitive Appraisal Theory 01:20

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...
