Real behavior in virtual environments: psychology experiments in a simple virtual-reality paradigm using video games

Area of Science:

• Psychology
• Virtual Environment Research
• Social Behavior

Background:

• Virtual environments (VEs) offer a novel platform for psychological research.
• Exploring complex social phenomena within VEs requires validation for ecological validity.
• Simple, accessible game-based VEs present a promising avenue for such research.

Purpose of the Study:

• To demonstrate the utility of simple video-game VEs for studying real-world social behaviors.
• To investigate the effects of time pressure and the bystander effect on helping behavior.
• To assess the compromise between experimental control and ecological validity in VEs.

Main Methods:

• Two experiments were conducted in a simple computer-game virtual environment.
• Participants navigated a virtual labyrinth under varying time pressure.
• Virtual bystanders were present or absent, with their numbers manipulated in the second experiment.

Main Results:

• Helping behavior was significantly reduced under high time pressure.
• A small number of virtual bystanders did not significantly affect helping.
• A large number of virtual bystanders significantly reduced helping, demonstrating the bystander effect.

Conclusions:

• Simple video-game VEs can effectively observe and manipulate complex social behaviors.
• This paradigm offers a valuable balance between experimental control and real-world relevance.
• VEs are a broadly useful tool for psychological research on behavior.
