B. Tversky和DJ Schiano（1989）报告了在“ell”框架中再现线的角度的偏见。当没有给出任务的概念性解释时，他们认为偏见是由于感知过程产生了明显的直线倾斜（DJ Schiano & B. Tversky, 1992）。我们认为，J. Huttenlocher、LV Hedges和S. Duncan（1991）的类别效应对刺激值估计的模型可以更好地解释这种偏差。提出了两个实验来检验这些不同的观点。结果显示，框架的方向和干扰任务对偏见的影响更符合J. Huttenlocher等人的模型，而不是DJ Schiano和B. Tversky采用的知觉解释。
B. Tversky and DJ Schiano (1989) reported bias in reproducing the angle of a line in an “ell” frame. When no conceptual interpretation of the task was given, they argued that the bias was due to a perceptual process that produced an apparent tilt in the line (DJ Schiano & B. Tversky, 1992). We propose that J. Huttenlocher, LV Hedges, and S. Duncan’s (1991) model of category effects on estimates of stimulus values provides a better explanation of this bias. Two experiments are presented that examine these alternative views. The results show effects of the orientation of the frame and of an interference task on bias that are more consistent with J. Huttenlocher et al.’s model than with the perceptual explanation adopted by DJ Schiano and B. Tversky.
