“…This has been found across different species (e.g., Gray et al, 2005; Murphy & Miller, 1958), tasks (Bennett, 1993; Padilla et al, 2017), and sensory modalities (Ellins et al, 1985; Rescorla & Cunningham, 1979). Moreover, when the distance between the cue and the goal is increased, the spatial behavioural control revealed by a landmark weakens, as observed in studies in rats (Chamizo & Rodrigo, 2004), pigeons (Spetch & Wilkie, 1994), toads (Sotelo et al, 2020), and humans (Chamizo et al, 2011). However, less is known about the interaction (i.e., cue competition) between different spatial cues when contiguity is manipulated.…”

Over the last 50 years, cue competition phenomena have shaped theoretical developments in animal and human learning. However, recent failures to observe competition effects in standard conditioning procedures, as well as the lengthy and ongoing debate surrounding cue competition in the spatial learning literature, have cast doubts on the generality of these phenomena. In the present study, we manipulated temporal contiguity between simultaneously trained predictors and outcomes (Experiments 1–4), and spatial contiguity between landmarks and goals in spatial learning ( Supplemental Experiments 1 and 2; Experiment 5 ). Across different parametric variations, we observed overshadowing when temporal and spatial contiguity were strong, but no overshadowing when contiguity was weak. Thus, across temporal and spatial domains, we observed that contiguity is necessary for competition to occur, and that competition between cues presented simultaneously during learning is absent when these cues were either spatially or temporally discontiguous from the outcome. Consequently, we advance a model in which the contiguity between events is accounted for and which explains these results and reconciles the previously contradictory findings observed in spatial learning.

“…This possibility seems less likely, however, in light of Tommasi and Polli’s (2004) conclusion that chicks represent local geometric features rather than global geometry. Nevertheless, Sotelo et al (2020) have recently found that the terrestrial toad, Rhinella arenarum , also fails to transfer between a rectangle and kite, and Sotelo et al (2016) showed that c-Fos activation in the medial pallium of the same species, a putative homologue of the mammalian HPC, increased as a result of exposure to environmental geometry. The possibility of between species differences therefore remains.…”

We examined the role of the hippocampus and the dorsolateral striatum in the representation of environmental geometry using a spontaneous object recognition procedure. Rats were placed in a kite-shaped arena and allowed to explore two distinctive objects in each of the right-angled corners. In a different room, rats were then placed into a rectangular arena with two identical copies of one of the two objects from the exploration phase, one in each of the two adjacent right-angled corners that were separated by a long wall. Time spent exploring these two objects was recorded as a measure of recognition memory. Since both objects were in different locations with respect to the room (different between exploration and test phases) and the global geometry (also different between exploration and test phases), differential exploration of the objects must be a result of initial habituation to the object relative to its local geometric context. The results indicated an impairment in processing the local geometric features of the environment for both hippocampus and dorsolateral striatum lesioned rats compared with sham-operated controls, though a control experiment showed these rats were unimpaired in a standard object recognition task. The dorsolateral striatum has previously been implicated in egocentric route-learning, but the results indicate an unexpected role for the dorsolateral striatum in processing the spatial layout of the environment. The results provide the first evidence that lesions to the hippocampus and dorsolateral striatum impair spontaneous encoding of local environmental geometric features.
