	Title	Varieties of learning and memory in animals			Type	Journal Article
	Year	1993	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	19	Issue	1	Pages	5-14
	Keywords	Animals; Association Learning; Birds; Conditioning, Classical; Evolution; Imprinting (Psychology); Learning; Memory; Social Environment; Species Specificity; Taste
	Abstract	It is often assumed that there is more than one kind of learning--or more than one memory system--each of which is specialized for a different function. Yet, the criteria by which the varieties of learning and memory should be distinguished are seldom clear. Learning and memory phenomena can differ from one another across species or situations (and thus be specialized) in a number of different ways. What is needed is a consistent theoretical approach to the whole range of learning phenomena, and one is explored here. Parallels and contrasts in the study of sensory systems illustrate one way to integrate the study of general mechanisms with an appreciation of species-specific adaptations.

	Title	Horses (Equus caballus) discriminate body odour cues from conspecifics			Type	Journal Article
	Year	2013	Publication		Abbreviated Journal	Animal Cognition
	Volume		Issue		Pages	1-5
	Keywords	Body odour; Discrimination; Equus caballus; Habituation; Social memory
	Abstract	Knowledge about social recognition and memory in animals can help us to determine appropriate management and husbandry techniques. In this study, we used a habituation–discrimination procedure to investigate the ability of horses (Equus caballus) to distinguish between the body odour samples of unfamiliar conspecifics. To pick up body odour, we rubbed material on the coat of horses and presented these unknown body odours to 16 different conspecifics of the same sex and similar age. The test consisted of two successive two-min presentations of a sample from one individual (e.g. individual ‘A’) and a simultaneous presentation of samples from individual ‘A’ and a novel individual (e.g. individual ‘B’) during a final third presentation. The results showed that horses, regardless of sex, decreased the time they spent investigating conspecific body odour across the initial two presentations—demonstrating habituation. In the final presentation, the results demonstrated successful discrimination of the previously experienced odour because horses investigated the novel olfactory sample (‘B’) significantly more than the pre-exposed sample (‘A’). Taken together, these findings suggest, for the first time, that horses are able to discriminate two stimuli derived from body odours of unfamiliar conspecifics over short period of time.

	Title	Learning and memorisation of two different tasks in horses: the effects of age, sex and sire			Type	Journal Article
	Year	1996	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	46	Issue	3-4	Pages	137-143
	Keywords	Horse; Learning; Memory; Instrumental task; Spatial task
	Abstract	Learning and memory abilities of 1-3 year old horses were assessed using instrumental and spatial tasks. No important differences were observed in the success of learning of the instrumental task (chest opening) according to sex or age. Younger females, however, seemed to learn more quickly. The offspring of a particular stallion were slower to learn than other horses. All horses memorised this task and opened the chest in a very short time in the second session. The animals that learned the task easily were not necessarily faster in the memorisation test. In the spatial task, learning ability did not seem to be related to age but more females than males were successful. The offspring of one stallion were more successful than other horses. Only 76% of the horses succeeded in the memorisation test, independently of age or sex. No correlation was found between the tasks in the latencies of either the learning or the memorisation tests for the same horses. The instrumental and spatial tasks may involve different processes.

	Title	Global and local spatial landmarks: their role during foraging by Columbian ground squirrels (Spermophilus columbianus)			Type	Journal Article
	Year	2006	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	9	Issue	1	Pages	71-80
	Keywords	Animals; Cues; Feeding Behavior/psychology; Female; Memory; Mental Recall; Orientation; Sciuridae/psychology; Space Perception; *Spatial Behavior
	Abstract	Locating food and refuge is essential for an animal's survival. However, little is known how mammals navigate under natural conditions and cope with given environmental constraints. In a series of six experiments, I investigated landmark-based navigation in free-ranging Columbian ground squirrels (Spermophilus columbianus). Squirrels were trained individually to find a baited platform within an array of nine identical platforms and artificial landmarks set up on their territories. After animals learned the location of the food platform in the array, the position of the latter with respect to local artificial, local natural, and global landmarks was manipulated, and the animal's ability to find the food platform was tested. When only positions of local artificial landmarks were changed, squirrels located food with high accuracy. When the location of the array relative to global landmarks was altered, food-finding accuracy decreased but remained significant. In the absence of known global landmarks, the presence of a familiar route and natural local landmarks resulted in significant but not highly accurate performance. Squirrels likely relied on multiple types of cues when orienting towards a food platform. Local landmarks were used only as a secondary mechanism of navigation, and were not attended to when a familiar route and known global landmarks were present. This study provided insights into landmark use by a wild mammal in a natural situation, and it demonstrated that an array of platforms can be employed to investigate landmark-based navigation under such conditions.

	Title	Preference for spatial cues in a non-storing songbird species			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	3	Pages	211-214
	Keywords	Animals; Association Learning/physiology; Cues; Feeding Behavior/physiology; Female; Male; Memory/physiology; Sex Factors; Songbirds/physiology; Space Perception/physiology; Spatial Behavior/physiology
	Abstract	Male mammals typically outperform their conspecific females on spatial tasks. A sex difference in cues used to solve the task could underlie this performance difference as spatial ability is reliant on appropriate cue use. Although comparative studies of memory in food-storing and non-storing birds have examined species differences in cue preference, few studies have investigated differences in cue use within a species. In this study, we used a one-trial associative food-finding task to test for sex differences in cue use in the great tit, Parus major. Birds were trained to locate a food reward hidden in a well covered by a coloured cloth. To determine whether the colour of the cloth or the location of the well was learned during training, the birds were presented with three wells in the test phase: one in the original location, but covered by a cloth of a novel colour, a second in a new location covered with the original cloth and a third in a new location covered by a differently coloured cloth. Both sexes preferentially visited the well in the training location rather than either alternative. As great tits prefer colour cues over spatial cues in one-trial associative conditioning tasks, cue preference appears to be related to the task type rather than being species dependent.

	Title	How marsh tits find their hoards: the roles of site preference and spatial memory			Type	Journal Article
	Year	1982	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	8	Issue	4	Pages	354-375
	Keywords	Animals; Appetitive Behavior; Birds; Cues; Discrimination Learning; Memory; Mental Recall; Orientation; *Space Perception
	Abstract	Marsh tits (Parus palustris) store single food items in scattered locations and recover them hours or days later. Some properties of the spatial memory involved were analyzed in two laboratory experiments. In the first, marsh tits were offered 97 sites for storing 12 seeds. They recovered a median of 65% of them 2-3 hr later, making only two errors per seed while doing so. Over trials, they used some sites more often than others, but during recovery they were more likely to visit a site of any preference value if they had stored a seed there that day than if they had not. Recovery performance was much worse if the experimenters moved the seeds between storage and recovery. A fixed search strategy that had some of the same average properties as the tits' search behavior also did worse than the real birds. In Experiment 2, any tendency to visit the same sites on successive daily tests in the aviary was placed in opposition to memory for storage sites by allowing the tits to store more seeds 2 hr after storing a first batch. They tended to avoid individual storage sites holding seeds from the first batch. When the tits searched for all the seeds 2 hr later, they tended to recover more seeds from the second batch than from the first, i.e., there was a recency effect.

	Title	Place versus response learning revisited: tests of blocking on the radial maze			Type	Journal Article
	Year	2005	Publication	Behavioral neuroscience	Abbreviated Journal	Behav Neurosci
	Volume	119	Issue	2	Pages	567-586
	Keywords	Animals; Association Learning; Male; Maze Learning; Memory; Rats; Rats, Long-Evans; Reproducibility of Results
	Abstract	Neurobiological and behavioral research indicates that place learning and response learning occur simultaneously, in parallel. Such findings seem to conflict with theories of associative learning in which different cues compete for learning. The authors conducted place+response training on a radial maze and then tested place learning and response learning separately by reconfiguring the maze in various ways. Consistent with the effects of manipulating place and response systems in the brain (M. G. Packard & J. L. McGaugh, 1996), well-trained rats showed strong place learning and strong response learning. Three experiments using associative blocking paradigms indicated that prior response learning interferes with place learning. Blocking and related tests can be used to better understand how memory systems interact during learning.

	Title	Win-shift and win-stay learning in the short-beaked echidna (Tachyglossus aculeatus)			Type	Journal Article
	Year	2002	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	5	Issue	2	Pages	79-84
	Keywords	Animals; Echidna/psychology; Ecology; Female; Learning; Memory; Predatory Behavior; Reinforcement (Psychology)
	Abstract	Numerous previous investigators have explained species differences in spatial memory performance in terms of differences in foraging ecology. In three experiments we attempted to extend these findings by examining the extent to which the spatial memory performance of echidnas (or “spiny anteaters”) can be understood in terms of the spatio-temporal distribution of their prey (ants and termites). This is a species and a foraging situation that have not been examined in this way before. Echidnas were better able to learn to avoid a previously rewarding location (to “win-shift”) than to learn to return to a previously rewarding location (to “win-stay”), at short retention intervals, but were unable to learn either of these strategies at retention intervals of 90 min. The short retention interval results support the ecological hypothesis, but the long retention interval results do not.

	Title	Long-term memory of individual identity in ant queens			Type	Journal Article
	Year	2007	Publication	Biology Letters	Abbreviated Journal	Biol Lett
	Volume	3	Issue	5	Pages	459-462
	Keywords	Aggression; Animals; Ants/physiology; Conditioning, Operant; Evolution; Female; Memory; *Recognition (Psychology); Social Dominance
	Abstract	Remembering individual identities is part of our own everyday social life. Surprisingly, this ability has recently been shown in two social insects. While paper wasps recognize each other individually through their facial markings, the ant, Pachycondyla villosa, uses chemical cues. In both species, individual recognition is adaptive since it facilitates the maintenance of stable dominance hierarchies among individuals, and thus reduces the cost of conflict within these small societies. Here, we investigated individual recognition in Pachycondyla ants by quantifying the level of aggression between pairs of familiar or unfamiliar queens over time. We show that unrelated founding queens of P. villosa and Pachycondyla inversa store information on the individual identity of other queens and can retrieve it from memory after 24h of separation. Thus, we have documented for the first time that long-term memory of individual identity is present and functional in ants. This novel finding represents an advance in our understanding of the mechanism determining the evolution of cooperation among unrelated individuals.

	Title	Successive reversal of concurrent discriminations by macaques (Macaca mulatta): proactive interference effects			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	2	Pages	75-83
	Keywords	Animals; Choice Behavior; Discrimination Learning; Female; Macaca mulatta/psychology; Memory; Proactive Inhibition; Random Allocation; *Reversal Learning
	Abstract	Rhesus monkeys received concurrent within-session training on eight, two-choice object pairs and then underwent successive reversals of these problems. Initially, reversals required about six times more training than acquisition with no improvement over seven successive reversals. Surprisingly, performance on these eight problems was unimpaired if they were embedded in different eight-problem tasks, thereby indicating a release from proactive interference. When the original eight problems again underwent successive reversal, no improvement was seen over seven reversals, although there was significantly less error-per-reversal than in the initial test. Subsequently, monkeys appeared to be developing a learning set for successive reversal because performance on successive reversal of eight novel problems was not different from that seen with the old familiar task. Set acquisition was confirmed when proficient reversal was eventually achieved on both old and new concurrent tasks. Thus, “concurrent reversal set” did develop, but it required arduous training to overcome proactive interference effects on memory. The ubiquitous influence of measurement context on organization of monkey memory was noted.
