	Title	Development of conditioning programs for dressage horses based on time-motion analysis of competitions			Type	Journal Article
	Year	1993	Publication	Journal of Applied Physiology (Bethesda, Md. : 1985)	Abbreviated Journal	J Appl Physiol
	Volume	74	Issue	5	Pages	2325-2329
	Keywords	Animals; Horses/physiology; Physical Conditioning, Animal; Sports; Statistics; Time Factors; Time and Motion Studies; Videotape Recording
	Abstract	The time-motion characteristics of Canadian basic- and medium-level dressage competitions are described, and the results are applied in formulating sport-specific conditioning programs. One competition was analyzed at the six levels from basic 1 to medium 3. Each test was divided into a series of sequences based on the type and speed of activity. The durations of the sequences were measured from videotapes. The basic-level tests had fewer sequences, and they were shorter in distance and duration than the medium tests (P < 0.10), but the average speed did not differ between the two levels. It is recommended that horses competing at the basic levels be conditioned using 5-min exercise periods, with short (10-s) bursts of lengthened trot and canter included at basic 2 and above. In preparation for medium-level competitions, the duration of the work periods increases to 7 min, 10- to 12-s bursts of medium or extended trot and canter are included, and transitions are performed frequently to simulate the energy expenditure in overcoming inertia.

	Title	Left ventricular size and systolic function in Thoroughbred racehorses and their relationships to race performance			Type	Journal Article
	Year	2005	Publication	Journal of Applied Physiology (Bethesda, Md. : 1985)	Abbreviated Journal	J Appl Physiol
	Volume	99	Issue	4	Pages	1278-1285
	Keywords	Adaptation, Physiological; Aging/physiology; Animal Husbandry; Animals; Echocardiography; Female; Heart/physiology; Heart Ventricles; Horses/physiology; Male; Physical Conditioning, Animal; Running/physiology; Stroke Volume; Systole; Task Performance and Analysis
	Abstract	Cardiac morphology in human athletes is known to differ, depending on the sports-specific endurance component of their events, whereas anecdotes abound about superlative athletes with large hearts. As the heart determines stroke volume and maximum O(2) uptake in mammals, we undertook a study to test the hypothesis that the morphology of the equine heart would differ between trained horses, depending on race type, and that left ventricular size would be greatest in elite performers. Echocardiography was performed in 482 race-fit Thoroughbreds engaged in either flat (1,000-2,500 m) or jump racing (3,200-6,400 m). Body weight and sex-adjusted measures of left ventricular size were largest in horses engaged in jump racing over fixed fences, compared with horses running shorter distances on the flat (range 8-16%). The observed differences in cardiac morphologies suggest that subtle differences in training and competition result in cardiac adaptations that are appropriate to the endurance component of the horses' event. Derived left ventricular mass was strongly associated with published rating (quality) in horses racing over longer distances in jump races (P < or = 0.001), but less so for horses in flat races. Rather, left ventricular ejection fraction and left ventricular mass combined were positively associated with race rating in older flat racehorses running over sprint (<1,408 m) and longer distances (>1,408 m), explaining 25-35% of overall variation in performance, as well as being closely associated with performance in longer races over jumps (23%). These data provide the first direct evidence that cardiac size influences athletic performance in a group of mammalian running athletes.

	Title	*A gray seal's (Halichoerus grypus) responses to experimenter-given pointing and directional cues*			Type	Journal Article
	Year	2003	Publication	Journal of Comparative Psychology	Abbreviated Journal	J Comp Psychol
	Volume	117	Issue	4	Pages	355-362
	Keywords	Animals; Behavior, Animal/physiology; Cognition/physiology; Conditioning, Operant/physiology; Cues; Eye Movements/physiology; Female; Seals, Earless
	Abstract	A gray seal (Halichoerus grypus) was trained to touch a target on its left or right by responding to pointing signals. The authors then tested whether the seal would be able to generalize spontaneously to altered signals. It responded correctly to center pointing and head turning, center upper body turning, and off-center pointing but not to head turning and eye movements alone. The seal also responded correctly to brief ipsilateral and contralateral points from center and lateral positions. Pointing gestures did not cause the seal to select an object placed centrally behind it. Like many animals in similar studies, this gray seal probably did not understand the referential character of these gestures but rather used signal generalization and experience from initial operant conditioning to solve these tasks.

	Title	Imitation of conditional discriminations in pigeons (Columba livia)			Type	Journal Article
	Year	2002	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	116	Issue	3	Pages	277-285
	Keywords	Animals; Behavior, Animal/physiology; Columbidae; Conditioning (Psychology)/physiology; Discrimination Learning/physiology; Habituation, Psychophysiologic; *Imitative Behavior; Light; Reinforcement (Psychology)
	Abstract	In the present experiments, the 2-action method was used to determine whether pigeons could learn to imitate a conditional discrimination. Demonstrator pigeons (Columba livia) stepped on a treadle in the presence of 1 light and pecked at the treadle in the presence of another light. Demonstration did not seem to affect acquisition of the conditional discrimination (Experiment 1) but did facilitate its reversal of the conditional discrimination (Experiments 2 and 3). The results suggest that pigeons are not only able to learn a specific behavior by observing another pigeon, but they can also learn under which circumstances to perform that behavior. The results have implications for proposed mechanisms of imitation in animals.

	Title	Timing in pigeons: effects of the similarity between intertrial interval and gap in a timing signal			Type	Journal Article
	Year	2002	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	28	Issue	4	Pages	416-422
	Keywords	Animals; Attention; Columbidae; Conditioning, Operant; Discrimination Learning; Mental Recall; Probability Learning; Reinforcement (Psychology); Reinforcement Schedule; Retention (Psychology); Time Factors; *Time Perception/physiology
	Abstract	Previous research suggests that when a fixed interval is interrupted (known as the gap procedure), pigeons tend to reset memory and start timing from 0 after the gap. However, because the ambient conditions of the gap typically have been the same as during the intertrial interval (ITI), ambiguity may have resulted. In the present experiment, the authors found that when ambient conditions during the gap were similar to the ITI, pigeons tended to reset memory, but when ambient conditions during the gap were different from the ITI, pigeons tended to stop timing, retain the duration of the stimulus in memory, and add to that time when the stimulus reappeared. Thus, when the gap was unambiguous, pigeons timed accurately.

	Title	Presence/absence-sample matching by pigeons: divergent retention functions may result from the similarity of behavior during the absence sample and the retention interval			Type	Journal Article
	Year	2000	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	26	Issue	3	Pages	294-304
	Keywords	Analysis of Variance; Animals; Behavior, Animal; Choice Behavior; Columbidae; Conditioning, Operant; Cues
	Abstract	Divergent choose-absence retention functions typically found in pigeons following presence/absence-sample matching have been attributed to the development of a single-code/default coding strategy. However, such effects may result from adventitious differential responding to the samples. In Experiment 1, retention functions were divergent only when differential sample responding could serve as the basis for comparison choice. In Experiment 2, when pecking did not occur during the retention interval, a choose-absence bias was found, but when pecking occurred during the retention interval, a choose-presence bias resulted. In Experiment 3, positive transfer was found when a stimulus associated with the absence of pecking replaced the absence sample but not when a stimulus associated with pecking replaced the presence sample. Thus, presence/absence-sample matching may not encourage the development of a single-code/default coding strategy in pigeons.

	Title	Value transfer in a simultaneous discrimination appears to result from within-event pavlovian conditioning			Type	Journal Article
	Year	1996	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	22	Issue	1	Pages	68-75
	Keywords	Animals; Behavior, Animal; Columbidae; Conditioning, Classical; Discrimination Learning; Female; Male; *Reinforcement (Psychology)
	Abstract	When pigeons acquire a simple simultaneous discrimination, some of the value acquired by the S+ transfers to the S-. The mechanism underlying this transfer of value was examined in three experiments. In Experiment 1, pigeons trained on two simultaneous discriminations (A + B- and C +/- D-) showed a preference for B over D. This preference was reduced, however, following the devaluation of A. In Experiment 2, when after the same original training, value was given to D, the pigeons' preference for C did not significantly increase. In Experiment 3, when both discriminations involved partial reinforcement (S +/-), A + C- training resulted in a preference for B over D, whereas B + D- training resulted in a preference for A over C. Thus, simultaneous discrimination training appears to result in bidirectional within-event conditioning involving the S+ and S-.

	Title	What-where-when memory in pigeons			Type	Journal Article
	Year	2006	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	4	Pages	345-358
	Keywords	Animals; Behavior, Animal/physiology; Columbidae; Conditioning, Operant/physiology; Memory/physiology; Reinforcement (Psychology); Space Perception/physiology; Spatial Behavior/physiology; Teaching; Visual Perception/physiology
	Abstract	The authors report a novel approach to testing episodic-like memory for single events. Pigeons were trained in separate sessions to match the identity of a sample on a touch screen, to match its location, and to report on the length of the retention interval. When these 3 tasks were mixed randomly within sessions, birds were more than 80% correct on each task. However, performance on 2 different tests in succession after each sample was not consistent with an integrated memory for sample location, time, and identity. Experiment 2 tested binding of location and identity memories in 2 different ways. The results were again consistent with independent feature memories. Implications for tests of episodic-like memory are discussed.

	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.
