As part of an experimental research program on lifespan naturalistic and laboratory memory for spatial representation, investigators examined interactions between the effects of visual and kinesthetic encoding and age on memory for space using a modification of the Sinnott (1987) human maze paradigm. It was hypothesized that an age effect favoring younger subjects would be present such that younger participants would perform better overall on the maze task, that older subjects would perform better on a Styrofoam mock-up of the maze-like floor plan compared with a paper version, and that the addition of kinesthetic information would prove especially helpful to older participants. Eighty-three older (mean age of 68.29) and 83 younger (mean age of 20.89) urban respondents were asked to remember a route through a building after being presented with one of four conditions giving either realistic or paper and pencil spatial information. The second two hypotheses were not supported; however, analysis supported the first hypothesis. Younger participants performed significantly better than older respondents on the right turn index, the turns index, the sequence of turns index, and the drawn to scale index. This research is consistent with other findings on the domain of spatial memory. (Author/ABL)
