Verbal Estimations of Time at Four Spatial Distances

Abstract

The method of verbal estimation was used to study the Kappa effect with unfilled, light-flash-bounded intervals of .5 to 22 sec. duration. Ss viewed dual flashes of one light and single flashes of paired lights set at 4-, 8-, 16-, and 32-in. horizontal separations. Group studies of 56 college students yielded evidence for larger estimations with greater light separation. A significant sex difference was found, female Ss giving longer estimations than males. 4 Ss were studied for 16 daily sessions to observe individual patterns and progressive changes in estimates.
