Participants' usage of informational variables in learning visual relative-mass discrimination in collisions was tracked by means of PROBIT correlations. Four groups received feedback that was true or accorded with either of three nonspecificational cue variables. A majority in each group adopted the feedback, but several participants defied the false feedback. Unlike in previous research, the fit to data of the relative-mass invariant could not be bettered by post hoc linear combinations of the cues. Discriminability was lower in the use of the invariant. Analytic complexity was rejected as an explanation for discriminability differences. A "smart mechanism" for pickup of the relative-mass invariant was developed as an extension of G. Johansson's (1950/1994) vector model.
通过概率单位相关性追踪参与者在学习碰撞中视觉相对质量辨别时对信息变量的使用情况。四组参与者收到的反馈是真实的，或者与三个非特定线索变量中的任何一个相符。每组中的大多数人接受了反馈，但有几位参与者无视了错误反馈。与之前的研究不同，线索的事后线性组合并不能比相对质量不变量的数据拟合更好。使用不变量时的辨别力较低。分析复杂性被排除作为辨别力差异的解释。作为G. 约翰松（1950/1994）向量模型的扩展，开发了一种用于获取相对质量不变量的“智能机制”。
