Summary
A technique is presented for modeling the performance of open-loop mechanisms or systems, where performance is measured by success or failure as a function of the selected target for movement along a constrained trajectory and without corrective feedback. A modification of signal detection theory is used, which normalizes dissimilar data and indicates two independent parameters of performance: (1) “discriminability” and (2) “optimality” of the distribution of selected moves. An illustrative application is made to experimental data.

Clearly the abiltiy to selct consistly a value of x and ability to avoid “failure” are interrelated in practical cases, so that the two situations are not directly comparable. The author is grateful to Prof. W.R. Ferrell of University of Arizona for comments on this and related points of the paper.
