Cynophobic fear adaptively extends peri-personal space

Area of Science:

• Neuroscience
• Psychology
• Human-computer interaction

Background:

• Peri-personal space (PPS) is crucial for social behavior, motor control, and body protection.
• The flexibility of PPS boundaries is known, but the influence of unreasonable fear on PPS is under-explored.
• Fear is hypothesized to extend PPS to enhance protective capabilities.

Purpose of the Study:

• To investigate how unreasonable fear influences the size of peri-personal space (PPS).
• To test the hypothesis that fear extends the neural representation of multisensory space around the body.
• To explore anxiety's role in tailoring PPS boundaries in response to fear-relevant stimuli.

Main Methods:

• Two groups of non-clinical participants (dog-fearful and non-fearful) were studied.
• Cynophobia sensitivity was assessed using a questionnaire.
• PPS extent was measured using looming auditory stimuli (dog growling vs. sheep bleating) via binaural rendering.

Main Results:

• Dog-fearful participants exhibited a larger PPS when exposed to the dog growling stimulus compared to non-fearful participants.
• PPS size was adaptively modulated by cynophobia (dog fear).
• Anxiety appears to tailor PPS boundaries when individuals encounter fear-relevant cues.

Conclusions:

• Anxiety, specifically cynophobia, demonstrably influences and expands peri-personal space.
• Findings suggest anxiety modulates spatial awareness for protective purposes.
• This research offers insights into anxiety disorders by linking spatial perception and interpersonal interaction, potentially informing new therapeutic strategies.
