Eighteen stimuli were created by orthogonally varying the area (A), perimeter (P), and exposure duration of checkerboard patterns. Subjects judged either the area and duration of the presented shapes (area-time group) or the perimeter and duration (perimeter-time group) of the same figures. Perceived duration, area, and perimeter varied with changes in the uninstructed an the instructed stimulus dimensions. The discussion focuses on the ability of subjects to control the allocation of attention to instructed stimulus dimensions, as well as on the evidence in the data in favor of detailed sequential or fast holistic processing. It is suggested that the concept of stimulus complexity, defined as P2/A, is useful in describing the temporal and spatial illusions obtained in this study.
通过正交改变棋盘图案的面积（A）、周长（P）和呈现持续时间，创建了18种刺激。受试者判断呈现形状的面积和持续时间（面积-时间组）或相同图形的周长和持续时间（周长-时间组）。感知到的持续时间、面积和周长随未被指示和被指示的刺激维度的变化而变化。讨论集中在受试者控制对被指示刺激维度的注意力分配的能力，以及数据中支持详细顺序或快速整体处理的证据。有人提出，定义为P2/A的刺激复杂性概念有助于描述本研究中获得的时间和空间错觉。
