The authors explore the effects of spatial and locational cueing upon the aggregated results of cognitive mapping data. Using four experimental data sets they demonstrate that locational cueing introduces random error into the analysis and that spatial cueing increases the relative and absolute accuracy of spatial products (external representations of spatial knowledge). These effects are consistent regardless of whether individual or place cognition is assessed. As such, location and spatial cueing compromise both construct and convergent validity, and the integrity of the conclusions from previous studies on cognitive mapping are brought into question. It is suggested that a multidata collection, multidata analysis approach should be adopted to highlight and compensate for these methodological weaknesses.
