An essential tension can be found between researchers interested in ecological validity and those concerned with maintaining experimental control. Research in the human neurosciences often involves the use of simple and static stimuli lacking many of the potentially important aspects of real world activities and interactions. While this research is valuable, there is a growing interest in the human neurosciences to use cues about target states in the real world via multimodal scenarios that involve visual, semantic, and prosodic information. These scenarios should include dynamic stimuli presented concurrently or serially in a manner that allows researchers to assess the integrative processes carried out by perceivers over time. Furthermore, there is growing interest in contextually embedded stimuli that can constrain participant interpretations of cues about a target's internal states. Virtual reality environments proffer assessment paradigms that combine the experimental control of laboratory measures with emotionally engaging background narratives to enhance affective experience and social interactions. The present review highlights the potential of virtual reality environments for enhanced ecological validity in the clinical, affective, and social neurosciences.
在关注生态效度的研究人员与关注维持实验控制的研究人员之间,可以发现一种基本的紧张关系。人类神经科学的研究通常涉及使用简单且静态的刺激,这些刺激缺乏现实世界活动和互动中许多潜在的重要方面。虽然这项研究很有价值,但人类神经科学领域越来越关注通过涉及视觉、语义和韵律信息的多模态场景来利用关于现实世界中目标状态的线索。这些场景应包括以一种允许研究人员评估感知者随时间进行的整合过程的方式同时或相继呈现的动态刺激。此外,人们越来越关注情境嵌入刺激,这种刺激可以限制参与者对关于目标内部状态线索的解释。虚拟现实环境提供了评估范式,将实验室测量的实验控制与引人入胜的情感背景叙事相结合,以增强情感体验和社会互动。本综述强调了虚拟现实环境在临床、情感和社会神经科学中增强生态效度的潜力。
