Virtual reality is becoming commonplace to study human behavior because it affords simulations of various situations, thus is advantageous for standardized training, education, and experimental research. However, virtual reality may not contain all sensory cues (e.g., smell, scent) and non-perceptual factors (e.g., consequence, time pressure) that would evoke behaviors normally exhibited in the real world. There is limited research on behavioral validity of participants in virtual reality experiments. Thus, the principal goal of this research is to study the validity of human behavior in virtual reality, and thereby strengthen the transferability and generalizability of findings. Researchers will benefit from this work, as they will be able to apply the postulated perceptual-behavioral framework. Society in general will benefit, as private industry will be able to leverage the outcomes and guidelines to yield enhanced virtual reality technologies and other consumer products. There are two primary research objectives. (1) Understand effects of immersion on perceptual-behavioral relationship in an immersive virtual environment. Immersion is a quantifiable measure of virtual reality. A more immersive virtual environment will offer, for example, more extensive cues than a less immersive virtual environment. (2) Study and characterize non-perceptual factors that influence behavioral validity in an immersive virtual environment. Non-perceptual factors include time pressure and consequences (but not life or death because it is virtual). Behaviors (performance and actions) exhibited by participants will be examined in both research objectives. Empirical experiments will be conducted to collect quantitative and qualitative data to support the investigation driven by these two research objectives.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

虚拟现实技术可以模拟各种场景，有利于标准化的培训、教育和实验研究，因此在研究人类行为方面越来越普遍。然而，虚拟现实可能不包含所有的感官线索（例如，气味，气味）和非感知因素（例如，后果，时间压力），这将唤起通常在真实的世界中表现出的行为。目前对虚拟现实实验参与者行为效度的研究还很有限。因此，本研究的主要目的是研究虚拟现实中人类行为的有效性，从而加强研究结果的可移植性和可推广性。研究人员将从这项工作中受益，因为他们将能够应用假设的感知行为框架。整个社会都将受益，因为私营企业将能够利用这些成果和指导方针来生产增强的虚拟现实技术和其他消费产品。 有两个主要的研究目标。 (1)了解沉浸式虚拟环境中沉浸感对感知-行为关系的影响。沉浸感是虚拟现实的一个可量化的衡量标准。例如，一个更加沉浸式的虚拟环境将提供比一个不太沉浸式的虚拟环境更广泛的提示。(2)研究和表征在沉浸式虚拟环境中影响行为有效性的非感知因素。非知觉因素包括时间压力和后果（但不是生或死，因为它是虚拟的）。参与者表现出的行为（表现和行动）将在两个研究目标中进行检查。将进行实证实验，以收集定量和定性数据，以支持这两个研究目标驱动的调查。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
