“…However, the outward direction to the food source was much less precise than the homing direction the subjects usually follow in our experimental conditions. This observation casts some doubt on the possibility that, in natural conditions, the animals might return to a recently discovered feeding site on the basis of path integration alone (Etienne et al 1991).…”

During locomotion, mammals update their position with respect to a fixed point of reference, such as their point of departure, by processing inertial cues, proprioceptive feedback and stored motor commands generated during locomotion. This so-called path integration system (dead reckoning) allows the animal to return to its home, or to a familiar feeding place, even when external cues are absent or novel. However, without the use of external cues, the path integration process leads to rapid accumulation of errors involving both the direction and distance of the goal. Therefore, even nocturnal species such as hamsters and mice rely more on previously learned visual references than on the path integration system when the two types of information are in conflict. Recent studies investigate the extent to which path integration and familiar visual cues cooperate to optimize the navigational performance.

“…From this analysis, it seems obvious that the spatial behaviors ofmammals and birds share a number of characteristics. Mammals and birds are able to orient to and navigate in their surroundings by means of different mechanisms-as, for example, by learning a particular sequence of responses to a goal (i.e., orientation; Mackintosh, 1965;Restle, 1957;Scharlock, 1955), by integrating their own spatial displacements over time (i.e., dead reckoning; Etienne, Hurni, Maurer, & Seguinot, 1991;Mittelstaedt & Mittelstaedt, 1982;St. Paul, 1982), by learning to directly approach an individual cue as if it were a beacon (i.e., guidance learning; Brodbeck, 1994;Clayton & Krebs, 1994;Cook & Tauro, 1999;Deutsch, 1960;, or by means of a variety of other egocentrically referenced representations oflandmarks (i.e., local views or snapshot mechanisms; Cartwright & Collett, 1983;Leonard & McNaughton, 1990).…”

Turtles (Pseudemys scripta) were trained in place, cue, and control arm maze procedures, The turtles learned both tasks with accuracy, Subsequent probe and transfer trials revealed guidance and mapping strategies by the cue and the place groups, respectively. Thus, the turtles in the cue procedure solved their task by directly approaching the single individual intramaze cue associated with the goal, whereas the animals in the place task seemed to be using a maplike representation based on the encoding of simultaneous spatial relationships between the goal and the extramaze visual cues. Furthermore, the turtles in the place task were able to navigate with accuracy to the goal from unfamiliar start places, and their performance was resistant to a partial loss of relevant environmental information. The results reveal for the first time, to our knowledge, spatial learning and memory capabilities in a reptile that closely parallel those described in mammals and birds.

“…Mice have been shown to reset and discontinue path integration upon arrival at their nest but not outside their nest (Alyan, 1996). In addition, hamsters are not as successful at using path integration to return to a feeding site from their nest as they are at using path integration to return to their nest from a feeding site (Etienne, Hurni, Maurer, & Seguinot, 1991).…”

The ability of rats to return to the start location was examined with a 4-arm radial water maze. The task required rats to find 2 hidden platforms in sequence. Rats were released from 1 of 3 arms and there was a platform located in the fourth arm. Once a rat found this platform, a 2nd platform was raised in another location, which was either the start location, for 1 group, or another fixed location, for a control group. Across 3 experiments, all rats learned the location of the 1st fixed platform in 80 to 120 trials. However, rats had difficulty finding a 2nd platform if it was at the start location. Control groups revealed that rats could learn 2 platform locations and that the difficulty in learning to return to the start location did not seem to be attributable to its aversive nature. In separate groups, exposure to the start location was increased by starting the rats from an initially stable platform. Rats still did not readily learn to return to the start location. The authors suggest that start location, when varied, cannot readily be used to define the location of a hidden platform.
