Summary
Virtual reality users can feel embodied in avatars, experiencing a sense of ownership and agency. This study proposes a standardized questionnaire to measure the degree of embodiment in virtual reality experiences.
Area of Science:
- Human-Computer Interaction
- Virtual Reality Studies
- Cognitive Psychology
Background:
- Users in virtual reality (VR) can embody first-person avatars, leading to a sense of body ownership and agency.
- This embodiment illusion is robust, even with avatar characteristics differing from the user's own body.
- Embodiment is crucial for social VR experiences and influences user attitudinal, social, perceptual, and behavioral effects.
Purpose of the Study:
- To review existing questionnaires measuring embodiment in virtual reality.
- To propose a standardized 25-question embodiment questionnaire based on prevalent literature.
- To encourage consistent measurement of embodiment in future VR research.
Main Methods:
- Literature review of questionnaires used in virtual reality embodiment studies.
- Identification of 25 prevalent questions across existing instruments.
- Proposal of a new, standardized embodiment questionnaire.
Main Results:
- Existing embodiment questionnaires vary significantly.
- A consensus on 25 core questions for measuring embodiment has been identified.
- A standardized questionnaire is proposed to enhance comparability across studies.
Conclusions:
- The degree of embodiment experienced in VR varies among participants.
- A standardized questionnaire is needed to reliably assess embodiment.
- Implementing this questionnaire will facilitate more consistent and comparable research on virtual reality embodiment.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

01:24Attachment Styles

Jeffrey Simpson's attachment theory suggests that early caregiver relationships shape lasting patterns of behavior and emotional regulation, known as attachment styles. These patterns are organized along two key dimensions: self-esteem and interpersonal trust. The intersection of these dimensions produces four primary attachment styles that typically persist throughout life and significantly influence how individuals form and maintain relationships.Secure Attachment StyleIndividuals with a...
