According to the embodied approach to visual perception, individuals scale the environment to their bodies. This approach highlights the central role of the body for immediate, situated action. The present experiments addressed whether body scaling--specifically, eye-height scaling--occurs in memory when action is not immediate. Participants viewed standard targets that were either the same height as, taller than, or shorter than themselves. Participants then viewed a comparison target and judged whether the comparison was taller or shorter than the standard target. Participants were most accurate when the standard target height matched their own heights, taking into account postural changes. Participants were biased to underestimate standard target height, in general, and to push standard target height away from their own heights. These results are consistent with the literature on eye-height scaling in visual perception and suggest that body scaling is not only a useful metric for perception and action, but is also preserved in memory.
根据具身视知觉方法,个体根据自身来调整环境大小。这种方法强调了身体在即时、情境化行动中的核心作用。本实验旨在探讨当行动不是即时的情况下,身体调整——特别是眼睛高度调整——是否会在记忆中发生。参与者观看了与自身高度相同、比自身高或比自身矮的标准目标。然后,参与者观看了一个比较目标,并判断该比较目标比标准目标高还是矮。当标准目标高度与参与者自身高度相匹配时,参与者的判断最为准确,同时考虑到姿势的变化。一般来说,参与者倾向于低估标准目标的高度,并将标准目标的高度推离自身高度。这些结果与视觉感知中眼睛高度调整的文献一致,表明身体调整不仅是感知和行动的有用指标,而且在记忆中也得到了保留。
