    • Effects of landmark distance and stability on accuracy of reward relocation 

      Pritchard, David James; Hurly, T. Andrew; Healy, Susan Denise (2015-07) - Journal article
      Although small-scale navigation is well studied in a wide range of species, much of what is known about landmark use by vertebrates is based on laboratory experiments. To investigate how vertebrates in the wild use landmarks, ...
    • Lateral entorhinal cortex lesions impair local spatial frameworks 

      Kuruvilla, Maneesh; Ainge, James Alexander (2017-05-17) - Journal article
      A prominent theory in the neurobiology of memory processing is that episodic memory is supported by contextually gated spatial representations in the hippocampus formed by combining spatial information from medial entorhinal ...
    • A new, robust, and generic method for the quick creation of smooth paths and near time-optimal path tracking 

      Bott, M. P. (University of St Andrews, 2011-11-30) - Thesis
      Robotics has been the subject of academic study from as early as 1948. For much of this time, study has focused on very specific applications in very well controlled environments. For example, the first commercial robots ...
    • Treating hummingbirds as feathered bees : a case of ethological cross-pollination 

      Pritchard, D. J.; Tello Ramos, M. C.; Muth, F.; Healy, S. D. (2017-12) - Journal item
      Hummingbirds feed from hundreds of flowers every day. The properties of these flowers provide these birds with a wealth of information about colour, space and time to guide how they forage. To understand how hummingbirds ...
    • Wild hummingbirds can use the geometry of a flower array 

      Hornsby, Mark A. W.; Healy, Susan D.; Hurly, T. Andrew (2017-06) - Journal article
      Animals use cues from their environment to orient in space and to navigate their surroundings. Geometry is a cue whose informational content may originate from the metric properties of a given environment, and its use has ...
    • Wild hummingbirds rely on landmarks not geometry when learning an array of flowers 

      Hurly, T. Andrew; Fox, Thomas A. O.; Zwueste, Danielle M.; Healy, Susan D. (2014-09) - Journal article
      Rats, birds or fish trained to find a reward in one corner of a small enclosure tend to learn the location of the reward using both nearby visual features and the geometric relationships of corners and walls. Because these ...
    • Wild hummingbirds require a consistent view of landmarks to pinpoint a goal location 

      Pritchard, David J.; Hurly, T. Andrew; Healy, Susan D. (2018-03) - Journal article
      One outcome of the extensive work on the ways that birds and insects use visual landmarks to return to a rewarded location is that they use landmarks differently. But this conclusion may have been reached because the almost ...
    • Wild rufous hummingbirds use local landmarks to return to rewarded locations 

      Pritchard, David James; Scott, Renee D.; Healy, Susan Denise; Hurly, Andrew T. (2016-01) - Journal article
      Animals may remember an important location with reference to one or more visual landmarks. In the laboratory, birds and mammals often preferentially use landmarks near a goal (“local landmarks”) to return to that location ...
