4项实验表明，对于那些背着沉重背包（实验1）、疲劳（实验2）、身体素质较差（实验3）、老年人和/或健康状况下降（实验4）的人来说，山丘显得更陡。视觉引导的动作不受这些生理潜力的操纵的影响。尽管意识和行动系统是分离的，但它们也被证明是相互关联的。研究发现，与意识和行动相关的转变的重新校准会随着生理潜力（健康水平、年龄和健康）的长期变化而发生，但不会随着短暂的变化（疲劳和负荷）而发生。研究结果是根据控制明确视觉意识和视觉引导行动的独立系统之间的时间依赖性协调来讨论的。
In 4 experiments, it was shown that hills appear steeper to people who are encumbered by wearing a heavy backpack (Experiment 1), are fatigued (Experiment 2), are of low physical fitness (Experiment 3), or are elderly and/or in declining health (Experiment 4). Visually guided actions are unaffected by these manipulations of physiological potential. Although dissociable, the awareness and action systems were also shown to be interconnected. Recalibration of the transformation relating awareness and actions was found to occur over long-term changes in physiological potential (fitness level, age, and health) but not with transitory changes (fatigue and load). Findings are discussed in terms of a time-dependent coordination between the separate systems that control explicit visual awareness and visually guided action.
