“…Additionally, there were two marginally significant interactions involving cues: the angle × cues interaction, F(7, 462) 0 2.59, p < .02, and the radius × angle × cues interaction, F(7, 462) 0 2.42, p < .02. Both of these interactions were consistent with previous research in which absolute error was reduced for targets closest to the cues (Fitting et al, 2008a(Fitting et al, , 2008b, with these effects stronger for long-radius than for short-radius targets.…”

In two experiments, participants navigated through a large arena within a virtual environment (VE) to a location encoded in memory from a map. In both experiments, participants recalled locations by navigating through the VE, but in Experiment 2, they additionally recalled the locations on the original map. Two cues were located outside and above the walls of the arena at either north-south locations or east-west locations. The pattern of angular bias was used to infer how the cues affected the creation of spatial categories influencing memory for location in the two tasks. When participants navigated to remembered locations in the VE, two cue-based spatial categories were inferred, with cues serving to demarcate the boundaries of the categories. When participants remembered locations on the original map, two cue-based categories were again formed, but with cues serving as category prototypes. The pattern of results implies that cue-based spatial categorization schemes may be formulated differently at the memory retrieval stage depending on task constraints.

“…has demonstrated that fine-grained memory is fragile and quickly decays, resulting in greater reliance on categorical coding (Fitting, Wedell, & Allen, 2008a, 2008bMerchant, Fortes, & Georgopoulos, 2004;Spencer & Hund, 2002). Therefore, the resolution to this seeming contradiction is that feature accumulation utilizes categorical codes, which are distinct from the fine-grained codes of spatial distance.…”

“…Thus, there may be diminishing benefits of extra cues. These are likely to be task dependent, as our human analog of the water maze study showed a significant improvement from two to four cues and our fixed orientation studies only began to show improvements with four or more cues Fitting et al, 2008b). Although one might argue that the enhanced memory performance with more cues is a foregone conclusion in a navigation task, other researchers have found essentially no effects when cues are removed on test trials Nadel et al, 1998).…”

“…Finally, we have found it useful to model the error in fine-grain memory as a function of the distance from the target location to the cue locations Fitting et al, 2008aFitting et al, , 2008b. Although it is difficult to obtain a pure measure of fine-grain error, much of the variation in absolute error (i.e., the unsigned distance from estimate to actual location) is based on this source of error.…”

“…A very influential determinant of the number and locations of prototypes that our current study builds on is the set of external cues located around the task field. In our recently reported experiments in this area Fitting, Wedell, & Allen, 2008a, 2008b, participants reproduced the location of a dot in a circular region under conditions that varied the number and locations of cues placed along the perimeter of the task field. Results indicated that the category structure used to encode spatial location was highly dependent on the stability of one's orientation to the task field.…”

Participants maneuvered a rat image through a circular region on the computer screen to find a hidden target platform, blending aspects of two well-known spatial tasks. Like the Morris water maze task, participants first experienced a series of learning trials before having to navigate to the hidden target platform from different locations and orientations. Like the dot-location task, they determined the location of a position within a two-dimensional circular region. This procedure provided a way to examine how the number of surrounding cues (1, 2, or 3) affects the memory for spatial location in navigation. Memory performance was better when there were more cues and when targets were close to cues, consistent with the idea that cues bolster fine-grain memory, especially in proximal regions. Early and late measures of bias in memory reflected biases in a direction toward the nearest cue, implicating a cue-based category structure of the navigational space. Collectively, results suggest cue-based spatial memory representations that have been inferred from the dot-location task generalize to a navigation task within a simple, computer-based environment, as demonstrated by the good fits of the spatial model developed for the dot-location task (Fitting, Wedell, & Allen, 2005.
