Distortions in location memory.

Memory for the location ofa briefly presented target is often distorted in systematic ways. When people remember dot locations within a circular space, they typically show memory biases that appear to reflect a categorical strategy. However, memory for a target location can also be biased toward visible markers or landmarks. In the presentstudy, we investigated the interaction of categorical and landmark effects by providing sectioning lines in a circular space. In the absence of lines, response biases showed categorical effects, whereas in the presence of lines, response biases suggested that participants used a landmark-based scheme. Possible relations between the strategies are discussed.
