Forgetting the Locations of Objects: Intentional Forgetting in Spatial Memory

Previous work has shown that people can intentionally forget information when they are cued to do so. Such directed forgetting has extensively been demonstrated with verbal information, but has rarely been investigated with spatial information. The present study therefore examined directed-forgetting effects in object location memory. Participants studied two successively presented 3×3 arrays, each composed of the same nine objects. The instruction was to memorize the locations of the objects which differed between the two arrays. Following presentation of the first array, participants received a cue to either forget or continue remembering the object locations of this array before studying the object locations of the second array. After a brief retention interval, object location memory for both arrays was tested. Results revealed that forget-cued participants showed impaired location memory for Array 1 and enhanced location memory for Array 2, relative to remember-cued participants. Notably, whereas the impairment effect was found regardless of whether Array 1 was tested before or after Array 2, the enhancement effect was found only when Array 2 was tested first. These findings suggest that people can exert control over their memories, being able to intentionally forget not only verbal information, but also spatial information. The results are discussed in terms of both inhibitory and non-inhibitory accounts of directed forgetting.
