In three experiments, rats were trained to locate a submerged platform in one of the base corners of a triangular arena above each of which was suspended one of two distinctive landmarks. In Experiment 1, it was established that these landmarks diffe...

Journal of experimental psychology. Animal behavior processes, 39(2), 126-139. https://doi.org/10.1037/a0031199

The effects of stimulus salience and cue validity in the overshadowing of geometric features of an enclosed arena by discrete landmarks were investigated in rats using the water maze paradigm. Experiment 1 established that in a rhomboid-shaped arena,...

Transfer of spatial search between environments in human adults and young children (Homo sapiens): implications for representation of local geometry by spatial systems (2013)
Journal Article
Lew, A., Usherwood, B., Fragkioudaki, F., Koukoumi, V., Smith, S., Austen, J., & McGregor, A. (2014). Transfer of spatial search between environments in human adults and young children (Homo sapiens): implications for representation of local geometry by spatial systems. Developmental Psychobiology, 56(3), 421-434. https://doi.org/10.1002/dev.21109

Whether animals represent environmental geometry in a global and/or local way has been the subject of recent debate. We applied a transfer of search paradigm between rectangular- and kite-shaped arenas to examine the performance of human adults (usin...

Clever crows or unbalanced birds? (2013)
Journal Article

Taylor et al. claimed that New Caledonian crows are capable of reasoning about “hidden causal agents.” Their recorded increases in hide inspections and abandoned trials in the unknown causal agent (UCA) condition relative to the human causal agent (H...

Spontaneous object recognition memory is maintained following transformation of global geometric properties (2013)
Journal Article
Poulter, S., Kosaki, Y., Easton, A., & McGregor, A. (2013). Spontaneous object recognition memory is maintained following transformation of global geometric properties. Journal of experimental psychology. Animal behavior processes, 39(1), 93-98. https://doi.org/10.1037/a0030698

Studies of spontaneous behavior to assess memory are widespread, but often the relationships of objects to contexts and spatial locations are poorly defined. We examined whether object-location memory was maintained following global, but not local, c...
