Human Factors and Behavioral Science: Performance in Locating Terminals on a High-Density Connector

Performance in Locating Terminals on a HighDensity Connector B y L . E. FLAMM* (Manuscript received October 6, 1981) In two experiments thirty participants located terminals on variations of a new main distributing frame connector. Abutting individual connectors in mirror image led to a higher termination density. Location times and errors were evaluated using deadline procedures. Experiment 1 results showed a high incidence of parallax, counting, and left-right reversal errors. Design modifications aimed at reducing these errors led to improved performance in Experiment 2. Parallax, counting errors, and location times were significantly reduced. The continued occurrence of left-right reversal errors is discussed.
