The role of distal landmarks and individual differences in acquiring spatial representations that support flexible and automatic wayfinding (2024)
Journal Article
Buckley, M. G., Austen, J. M., & McGregor, A. (2024). The role of distal landmarks and individual differences in acquiring spatial representations that support flexible and automatic wayfinding. Journal of Environmental Psychology, 98, Article 102391. https://doi.org/10.1016/j.jenvp.2024.102391

Theories of parallel memory systems suggest that flexible wayfinding (e.g., shortcutting) requires knowledge about the spatial structure of an environment, whereas automatic wayfinding (e.g., route-following) does not. Distal landmarks have widely be... Read More about The role of distal landmarks and individual differences in acquiring spatial representations that support flexible and automatic wayfinding.

The well‐worn route revisited: Striatal and hippocampal system contributions to familiar route navigation (2024)
Journal Article
Buckley, M., McGregor, A., Ihssen, N., Austen, J., Thurlbeck, S., Smith, S. P., Heinecke, A., & Lew, A. R. (2024). The well‐worn route revisited: Striatal and hippocampal system contributions to familiar route navigation. Hippocampus, 34(7), 310-326. https://doi.org/10.1002/hipo.23607

Classic research has shown a division in the neuroanatomical structures that support flexible (e.g., short‐cutting) and habitual (e.g., familiar route following) navigational behavior, with hippocampal–caudate systems associated with the former and p...

Precision in spatial working memory examined with mouse pointing (2023)
Journal Article
McAteer, S. M., McAteer, S. M., McGregor, A., Smith, D. T., & Smith, D. T. (2024). Precision in spatial working memory examined with mouse pointing. Vision Research, 215, Article 108343. https://doi.org/10.1016/j.visres.2023.108343

The capacity of visuospatial working memory (VSWM) is limited. However, there is continued debate surrounding the nature of this capacity limitation. The resource model (Bays et al., 2009) proposes that VSWM capacity is limited by the precision with... Read More about Precision in spatial working memory examined with mouse pointing.

Dynamic resource allocation in spatial working memory during full and partial report tasks (2023)
Journal Article
McAteer, S. M., Ablott, E., McGregor, A., & Smith, D. T. (2023). Dynamic resource allocation in spatial working memory during full and partial report tasks. Journal of Vision, 23(2), Article 10. https://doi.org/10.1167/jov.23.2.10

Serial position effects are well-documented in working memory literature. Studies of spatial short-term memory that rely on binary response; full report tasks tend to report stronger primacy than recency effects. In contrast, studies that utilize a c...

Frequency matters: how changes in hippocampal theta frequency can influence temporal coding, anxiety-reduction, and memory (2023)
Journal Article
Hines, M., Poulter, S., Douchamps, V., Pibiri, F., McGregor, A., & Lever, C. (2023). Frequency matters: how changes in hippocampal theta frequency can influence temporal coding, anxiety-reduction, and memory. Frontiers in Systems Neuroscience, 16, https://doi.org/10.3389/fnsys.2022.998116

Hippocampal theta frequency is a somewhat neglected topic relative to theta power, phase, coherence, and cross-frequency coupling. Accordingly, here we review and present new data on variation in hippocampal theta frequency, focusing on functional as...

Oculomotor rehearsal in visuospatial working memory (2022)
Journal Article
McAteer, S. M., McGregor, A., & Smith, D. T. (2023). Oculomotor rehearsal in visuospatial working memory. Attention, Perception, and Psychophysics, 85(1), 261-275. https://doi.org/10.3758/s13414-022-02601-4

The neural and cognitive mechanisms of spatial working memory are tightly coupled with the systems that control eye movements, but the precise nature of this coupling is not well understood. It has been argued that the oculomotor system is selectivel... Read More about Oculomotor rehearsal in visuospatial working memory.

The spatial layout of doorways and environmental boundaries shape the content of event memories (2022)
Journal Article
Buckley, M. G., Myles, L. A., Easton, A., & McGregor, A. (2022). The spatial layout of doorways and environmental boundaries shape the content of event memories. Cognition, 225, Article 105091. https://doi.org/10.1016/j.cognition.2022.105091

Physical boundaries in our environment have been observed to define separate events in episodic memory. To date, however, there is little evidence that the spatial properties of boundaries exert any control over event memories. To examine this possib...

The effects of spatial stability and cue type on spatial learning: Implications for theories of parallel memory systems (2021)
Journal Article
Buckley, M. G., Austen, J. M., Myles, L. A., Smith, S., Ihssen, N., Lew, A. R., & McGregor, A. (2021). The effects of spatial stability and cue type on spatial learning: Implications for theories of parallel memory systems. Cognition, 214, Article 104802. https://doi.org/10.1016/j.cognition.2021.104802

Some theories of spatial learning predict that associative rules apply under only limited circumstances. For example, learning based on a boundary has been claimed to be immune to cue competition effects because boundary information is the basis for...

Uncertainty and predictiveness modulate attention in human predictive learning (2020)
Journal Article
Chao, C.-M., McGregor, A., & Sanderson, D. J. (2021). Uncertainty and predictiveness modulate attention in human predictive learning. Journal of Experimental Psychology: General, 150(6), 1177-1202. https://doi.org/10.1037/xge0000991

Attention determines which cues receive processing and are learned about. Learning, however, leads to attentional biases. In the study of animal learning, in some circumstances, cues that have been previously predictive of their consequences are subs...
