Visual localization of briefly presented peripheral targets.

Reported here are the results from two experiments designed to investigate Mateeff and Gourevich's (1983, 1984) claim that adult observers make large constant errors when judging the direction of briefly presented peripheral targets, with respect to a continuously visible scale. Experiment 1 involved a virtually exact duplication of Mateeff and Gourevich's paradigm. Experiment 2 involved adjusting the position of a light emitting diode (LED) so as to match the direction of a LED previously flashed in the periphery. No significant constant errors were found in either experiment.
