Abstract: | The effect of a large stationary landmark on memory for the location of a stationary target was examined. Memory for a stationary
target was displaced toward the landmark, and targets that were larger, further from, or above the landmark exhibited greater
magnitudes of displacement. Displacement was generally larger when the landmark vanished prior to judgment than when the landmark
was visible during judgment. Memory for stationary targets offset from the major vertical or horizontal cardinal axis of the
landmark was also displaced toward that cardinal axis. The data support the hypotheses that spatial memory averaging of the
locations of a target and landmark occurs, and that this averaging may be combined with representational gravity in determining
the remembered position of a stationary target.
