在判断室内空间时,深色天花板被判断为低于浅色天花板。在这类任务中通常使用的度量判断方法(例如,在厘米尺度上)可能反映了真正的感知效果,或者它可能反映了认知中介的印象。我们采用了高度匹配的方法,在这种方法中,感知的天花板高度必须与可调整的柱子相匹配,从而获得允许估计主观等值点(PSE)和差值阈值(DL)的心理测量函数。本文提出的高度匹配方法允许直接的视觉匹配,不需要度量判断。它还有一个额外的优势,那就是提供了超高的精度。实验一使用的天花板高度在2.9 m到3.00 m之间。事实证明,PSE对感知的天花板高度的轻微变化很敏感。DL约为实际天花板高度的3%。实验2在较低(2.30 m至2.50 m)和较高(3.30 m至3.5 m)天花板上发现了类似的结果。在实验3中,我们还改变了天花板的亮度(浅灰色和深灰色)。高度匹配显示,浅色天花板看起来明显高于深色天花板。因此,我们将天花板亮度对感知天花板高度的影响归因于直接的知觉效应,而不是认知效应。
When judging interior space, a dark ceiling is judged to be lower than a light ceiling. The method of metric judgments (e.g., on a centimetre scale) that has typically been used in such tasks may reflect a genuine perceptual effect or it may reflect a cognitively mediated impression. We employed a height-matching method in which perceived ceiling height had to be matched with an adjustable pillar, thus obtaining psychometric functions that allowed for an estimation of the point of subjective equality (PSE) and the difference limen (DL). The height-matching method developed in this paper allows for a direct visual match and does not require metric judgment. It has the added advantage of providing superior precision. Experiment 1 used ceiling heights between 2.90 m and 3.00 m. The PSE proved sensitive to slight changes in perceived ceiling height. The DL was about 3% of the physical ceiling height. Experiment 2 found similar results for lower (2.30 m to 2.50 m) and higher (3.30 m to 3.50 m) ceilings. In Experiment 3, we additionally varied ceiling lightness (light grey vs. dark grey). The height matches showed that the light ceiling appeared significantly higher than the darker ceiling. We therefore attribute the influence of ceiling lightness on perceived ceiling height to a direct perceptual rather than a cognitive effect.
