	Title	Concurrent disjoint and reciprocal classification by Cebus apella in seriation tasks: evidence for hierarchical organization			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	3	Pages	185-197
	Keywords	Animals; Cebus/physiology; Discrimination Learning/physiology; Female; Form Perception/physiology; Male; Task Performance and Analysis; Visual Perception/*physiology
	Abstract	We report the results of a 4-year-long study of capuchin monkeys ( Cebus apella ) on concurrent three-way classification and linear size seriation tasks using explicit ordering procedures, requiring subjects to select icons displayed on touch screens rather than manipulate and sort actual objects into groups. The results indicate that C. apella is competent to classify nine items concurrently, first into three disjoint classes where class exemplars are identical to one another, then into three reciprocal classes which share common exemplar (size) features. In the final phase we compare the relative efficiency of executive control under conditions where both hierarchical and/or linear organization can be utilized. Whilst this shows a superiority of categorical based size seriation for a nine item test set suggesting an adaptive advantage for hierarchical over linear organization, Cebus nevertheless achieved high levels of principled linear size seriation with sequence lengths not normally achieved by children below the age of six years.

	Title	Task preparation in macaque monkeys ( Macaca mulatta)			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	2	Pages	121-130
	Keywords	Animals; Cognition; Conditioning, Classical; Macaca mulatta/psychology; Male; Reaction Time; Task Performance and Analysis; Visual Perception
	Abstract	We investigated whether macaque monkeys possess the ability to prepare abstract tasks in advance. We trained two monkeys to use different stimulus-response (S-R) mappings. On each trial, monkeys were first informed with a visual cue which of two S-R mapping to use. Following a delay, a visual target was presented to which they would respond with a left or right button-press. We manipulated delay time between cue and target and found that performance was faster and more accurate with longer delays, suggesting that monkeys used the delay time to prepare each task in advance.

	Title	Gorilla ( Gorilla gorilla gorilla) and orangutan ( Pongo abelii) understanding of first- and second-order relations			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	2	Pages	77-86
	Keywords	Animals; Cognition; Color Perception; Female; Gorilla gorilla/psychology; Male; Pongo pygmaeus/*psychology; Task Performance and Analysis
	Abstract	Four orangutans and one gorilla matched images in a delayed matching-to-sample (DMTS) task based on the relationship between items depicted in those images, thus demonstrating understanding of both first- and second-order relations. Subjects matched items on the basis of identity, color, or shape (first-order relations, experiment 1) or same shape, same color between items (second-order relations, experiment 2). Four of the five subjects performed above chance on the second-order relations DMTS task within the first block of five sessions. High levels of performance on this task did not result from reliance on perceptual feature matching and thus indicate the capability for abstract relational concepts in two species of great ape.

	Title	Age differences in neophilia, exploration, and innovation in family groups of callitrichid monkeys			Type	Journal Article
	Year	2005	Publication	American journal of primatology	Abbreviated Journal	Am. J. Primatol.
	Volume	66	Issue	2	Pages	167-188
	Keywords	Age Factors; Analysis of Variance; Animals; Animals, Zoo; Behavior, Animal/physiology; Callitrichinae/physiology; Creativeness; Exploratory Behavior/*physiology; Observation; Social Behavior; Task Performance and Analysis
	Abstract	The prevailing assumption in the primate literature is that young or juvenile primates are more innovative than adult individuals. This innovative tendency among the young is frequently thought to be a consequence, or side effect, of their increased rates of exploration and play. Conversely, Reader and Laland's [International Journal of Primatology 22:787-806, 2001] review of the primate innovation literature noted a greater reported incidence of innovation in adults than nonadults, which they interpreted as (in part) a reflection of the greater experience and competence of older individuals. Within callitrichids there is contradictory evidence for age differences in response to novel objects, foods, and foraging tasks. By presenting novel extractive foraging tasks to family groups of callitrichid monkeys in zoos, we examined, in a large sample, whether there are positive or negative relationships of age with neophilia, exploration, and innovation, and whether play or experience most facilitates innovation. The results indicate that exploration and innovation (but not neophilia) are positively correlated with age, perhaps reflecting adults' greater manipulative competence. To the extent that there was evidence for play in younger individuals, it did not appear to contribute to innovation. The implications of these findings for the fields of innovation and conservation through reintroduction are considered.

	Title	Role of differential sample responding in the differential outcomes effect involving delayed matching by pigeons			Type	Journal Article
	Year	1994	Publication	Journal of experimental psychology. Animal behavior processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	20	Issue	4	Pages	390-401
	Keywords	Animals; Behavior, Animal; Choice Behavior; Columbidae; Discrimination Learning; Feeding Behavior; Task Performance and Analysis
	Abstract	The role of differential sample responding in the differential outcomes effect was examined. In Experiment 1, we trained pigeons on a one-to-many matching task with differential sample responding required. Differential outcomes were associated with samples and comparisons, with comparisons only, or with neither samples nor comparisons. Slopes of delay functions for trials with pecked versus nonpecked samples suggested use of a single-code-default strategy in the nondifferential-outcomes group but not in the differential-outcomes groups. In Experiment 2, differential sample responding and differential outcomes were manipulated independently. Again, there were significant differences in the relative slopes of the delay functions. Results suggest that differential outcomes exert their effect independently of differential sample responding.

	Title	Directed forgetting in animals			Type	Journal Article
	Year	1993	Publication	Psychological bulletin	Abbreviated Journal	Psychol Bull
	Volume	113	Issue	3	Pages	513-532
	Keywords	Animals; Behavior, Animal; Cognition; Columbidae; Conditioning (Psychology); Discrimination Learning; Female; Humans; Male; Memory Disorders/psychology; Reinforcement (Psychology); Task Performance and Analysis
	Abstract	Directed-forgetting research with animals suggests that animals show disrupted test performance only under certain conditions. Important variables are (a) whether during training, the cue to forget (F cue) signals nonreward (i.e., that the trial is over) versus reward (i.e., that reinforcement can be obtained) and (b) given that reinforcement can be obtained on F-cue trials, whether the post-F-cue response pattern is compatible with the baseline memory task. It is proposed that some findings of directed forgetting can be attributed to trained response biases, whereas others may be attributable perhaps to frustration-produced interference. It is suggested that directed forgetting in animals should be studied using procedures similar to those used to study directed forgetting in humans. This can be accomplished by presenting, within a trial, both to-be-remembered and to-be-forgotten material.

	Title	Effects of the rider on the linear kinematics of jumping horses			Type	Journal Article
	Year	2002	Publication	Sports Biomechanics / International Society of Biomechanics in Sports	Abbreviated Journal	Sports Biomech
	Volume	1	Issue	2	Pages	135-146
	Keywords	Animals; Behavior, Animal/physiology; Biomechanics; Communication; Exertion/physiology; Gait/physiology; Horses/physiology; Humans; Locomotion/physiology; Posture/physiology; Task Performance and Analysis; Video Recording; Weight-Bearing/*physiology
	Abstract	This study examined the effects of the rider on the linear projectile kinematics of show-jumping horses. SVHS video recordings (50 Hz) of eight horses jumping a vertical fence 1 m high were used for the study. Horses jumped the fence under two conditions: loose (no rider or tack) and ridden. Recordings were digitised using Peak Motus. After digitising the sequences, each rider's digitised data were removed from the ridden horse data so that three conditions were examined: loose, ridden (including the rider's data) and riderless (rider's data removed). Repeated measures ANOVA revealed significant differences between ridden and loose conditions for CG height at take-off (p < 0.001), CG distance to the fence at take-off (p = 0.001), maximum CG during the suspension phase (p < 0.001), CG position over the centre of the fence (p < 0.001), CG height at landing (p < 0.001), and vertical velocity at take-off (p < 0.001). The results indicated that the rider's effect on jumping horses was primarily due to behavioural changes in the horses motion (resulting from the rider's instruction), rather than inertial effects (due to the positioning of the rider on the horse). These findings have implications for the coaching of riders and horses.

	Title	Quantity-based interference and symbolic representations in chimpanzees (Pan troglodytes)			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	76-86
	Keywords	Animals; Behavior, Animal; Cognition; Discrimination Learning; Female; Male; Pan troglodytes; *Reinforcement (Psychology); Task Performance and Analysis
	Abstract	Five chimpanzees with training in counting and numerical skills selected between 2 arrays of different amounts of candy or 2 Arabic numerals. A reversed reinforcement contingency was in effect, in which the selected array was removed and the subject received the nonselected candies (or the number of candies represented by the nonselected Arabic numeral). Animals were unable to maximize reward by selecting the smaller array when candies were used as array elements. When Arabic numerals were substituted for the candy arrays, all animals showed an immediate shift to a more optimal response strategy of selecting the smaller numeral, thereby receiving the larger reward. Results suggest that a response disposition to the high-incentive candy stimuli introduced a powerful interference effect on performance, which was effectively overridden by the use of symbolic representations.

	Title	Responses to quantity: perceptual versus cognitive mechanisms in chimpanzees (Pan troglodytes)			Type	Journal Article
	Year	1995	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	21	Issue	1	Pages	82-86
	Keywords	Animals; Behavior, Animal; Choice Behavior; Cognition/physiology; Female; Pan troglodytes; Perception/*physiology; Reinforcement (Psychology); Task Performance and Analysis
	Abstract	Two chimpanzees were trained to select among 2 different amounts of candy (1-6 items). The task was designed so that selection of either array by the active (selector) chimpanzee resulted in that array being given to the passive (observer) animal, with the remaining (nonselected) array going to the selector. Neither animal was able to select consistently the smaller array, which would reap the larger reward. Rather, both animals preferentially selected the larger array, thereby receiving the smaller number of reinforcers. When Arabic numerals were substituted for the food arrays, however, the selector animal evidenced more optimal performance, immediately selecting the smaller numeral and thus receiving the larger reward. These findings suggest that a basic predisposition to respond to the perceptual-motivational features of incentive stimuli can interfere with task performance and that this interference can be overridden when abstract symbols serve as choice stimuli.

	Title	Landmark discrimination learning in the dog: effects of age, an antioxidant fortified food, and cognitive strategy			Type	Journal Article
	Year	2002	Publication	Neuroscience and Biobehavioral Reviews	Abbreviated Journal	Neurosci Biobehav Rev
	Volume	26	Issue	6	Pages	679-695
	Keywords	Age Factors; Aging/physiology; Analysis of Variance; Animals; Antioxidants/pharmacology; Blood Chemical Analysis/methods; Cognition/physiology; Diet; Discrimination Learning/drug effects/physiology; Distance Perception/drug effects/physiology; Dogs/physiology; Female; Male; Psychomotor Performance/physiology; Retention (Psychology)/drug effects/physiology; Spatial Behavior/drug effects/physiology; Task Performance and Analysis; Time Factors; Vitamin E/blood
	Abstract	The landmark discrimination learning test can be used to assess the ability to utilize allocentric spatial information to locate targets. The present experiments examined the role of various factors on performance of a landmark discrimination learning task in beagle dogs. Experiments 1 and 2 looked at the effects of age and food composition. Experiments 3 and 4 were aimed at characterizing the cognitive strategies used in performance on this task and in long-term retention. Cognitively equivalent groups of old and young dogs were placed into either a test group maintained on food enriched with a broad-spectrum of antioxidants and mitochondrial cofactors, or a control group maintained on a complete and balanced food formulated for adult dogs. Following a wash-in period, the dogs were tested on a series of problems, in which reward was obtained when the animal responded selectively to the object closest to a thin wooden block, which served as a landmark. In Experiment 1, dogs were first trained to respond to a landmark placed directly on top of coaster, landmark 0 (L0). In the next phase of testing, the landmark was moved at successively greater distances (1, 4 or 10 cm) away from the reward object. Learning varied as a function of age group, food group, and task. The young dogs learned all of the tasks more quickly than the old dogs. The aged dogs on the enriched food learned L0 significantly more rapidly than aged dogs on control food. A higher proportion of dogs on the enriched food learned the task, when the distance was increased to 1cm. Experiment 2 showed that accuracy decreased with increased distance between the reward object and landmark, and this effect was greater in old animals. Experiment 3 showed stability of performance, despite using a novel landmark, and new locations, indicating that dogs learned the landmark concept. Experiment 4 found age impaired long-term retention of the landmark task. These results indicate that allocentric spatial learning is impaired in an age-dependent manner in dogs, and that age also affects performance when the distance between the landmark and target is increased. In addition, these results both support a role of oxidative damage in the development of age-associated cognitive dysfunction and indicate that short-term administration of a food enriched with supplemental antioxidants and mitochondrial cofactors can partially reverse the deleterious effects of aging on cognition.
