在陆地环境中，对感知的特定影响是明显的。例如，需要更多努力来行走，跳跃或投掷的目标比目标需要更少努力时看得更远。在这里，我们研究了特定动作的影响是否会推广到水下环境。相反，从进化的角度来看，在一个新的环境中，感知可能是几何精确的，而不是特定于行动的。我们通过给参与者提供或拿走他们的游泳鳍来操纵游泳。那些戴着脚蹼估计距离的人判断水下目标比脱下脚蹼的人更近。此外，游泳能力较好的参与者判断目标比游泳能力较差的参与者更接近。这些结果表明，水下感知距离是感知者游泳到目标的能力的函数。
Action-specific effects on perception are apparent in terrestrial environments. For example, targets that require more effort to walk, jump, or throw to look farther away than when the targets require less effort. Here, we examined whether action-specific effects would generalize to an underwater environment. Instead, perception might be geometrically precise, rather than action-specific, in an environment that is novel from an evolutionary perspective. We manipulated ease to swim by giving participants swimming flippers or taking them away. Those who estimated distance while wearing the flippers judged underwater targets to be closer than did participants who had taken them off. In addition, participants with better swimming ability judged the targets to be closer than did those with worse swimming ability. These results suggest perceived distance underwater is a function of the perceiver's ability to swim to the targets.
