Dimensional analysis of motion: V. An analytic test of psychomotor ability

Abstract

The authors describe a new "… psychomotor test for separate measurement of the travel and manipulation components of motion… " called the Analytic Reactometer. Subjects are required to manipulate 25 rotary switches on a control panel. Electric clocks time various aspects of the motion. Scores are in terms of time. Typical distributions of test scores are presented. Reliabilities of specific tests related to hand travel, planes, directions of travel, direction of manipulation and complexity of manipulation pattern are reported ranging from .81 to .87 for manipulation, and from .69 to .81 for travel. Correlations between manipulation and travel range from .25 to .41. The authors present the test as useful in securing precise and analytical data "… for exact quantitative specification of motions and motion functions."
