Hypersensitivity to Contingent Behavior in Paranoia: A New Virtual Reality Paradigm

Area of Science:

• Psychology
• Human-Computer Interaction
• Virtual Reality

Background:

• Interpersonal contingency fosters secure attachment and trust, while paranoia stems from attributing negative intentions.
• Understanding how paranoia influences trust perception in social interactions is crucial.

Purpose of the Study:

• To experimentally investigate the impact of contingent behavior on trust in individuals across the paranoia spectrum.
• To explore the role of virtual reality in simulating social interactions and assessing trust.

Main Methods:

• A virtual reality paradigm was used with 61 healthy participants interacting with a virtual human (avatar).
• Participants were randomly assigned to high or low contingency conditions (avatar responsiveness).
• Perceived trustworthiness, trusting behavior, attachment styles, and anxiety were assessed.

Main Results:

• Higher paranoia and dismissive attachment correlated with greater interpersonal distances.
• Extremely paranoid individuals reported higher trustworthiness of the highly contingent avatar compared to the low contingency avatar.
• Dismissive attachment was linked to increased subjective trust regardless of avatar contingency.

Conclusions:

• Extreme paranoia may involve hypersensitivity to noncontingent social cues, potentially explaining mistrust in everyday interactions.
• Virtual reality offers a controlled environment to study the nuances of trust and paranoia in social contexts.
• Findings highlight the complex interplay between paranoia, attachment, and trust in human-avatar interactions.
