	Title	The implications of cognitive processes for animal welfare			Type	Journal Article
	Year	1991	Publication	Journal of Animal Science	Abbreviated Journal	J. Anim Sci.
	Volume	69	Issue	12	Pages	5017-5022
	Keywords	Animal Welfare; Animals; Animals, Domestic/psychology; *Cognition
	Abstract	In general, codes that have been designed to safeguard the welfare of animals emphasize the importance of providing an environment that will ensure good health and a normal physiological and physical state, that is, they emphasize the animals' physical needs. If mental needs are mentioned, they are always relegated to secondary importance. The argument is put forward here that animal welfare is dependent solely on the cognitive needs of the animals concerned. In general, if these cognitive needs are met, they will protect the animals' physical needs. It is contended that in the few cases in which they do not safeguard the physical needs, it does not matter from a welfare point of view. The human example is given of being ill. It is argued that welfare is only adversely affected when a person feels ill, knows that he or she is ill, or even thinks that he or she is ill, all of which processes are cognitive ones. The implications for welfare of animals possessing certain cognitive abilities are discussed. For example, the extent to which animals are aware of their internal state while performing behavior known to be indicative of so-called states of suffering, such as fear, frustration, and pain, will determine how much they are actually suffering. With careful experimentation it may be possible to determine how negative they feel these states to be. Similarly, the extent to which animals think about items or events absent from their immediate environment will determine how frustrated they are in the absence of the real item or event but in the presence of the cognitive representation.

	Title	The importance of animal cognition in agricultural animal production systems: an overview			Type	Journal Article
	Year	1991	Publication	Journal of Animal Science	Abbreviated Journal	J. Anim Sci.
	Volume	69	Issue	12	Pages	5001-5007
	Keywords	Agriculture; Animal Population Groups/psychology; Animal Welfare; Animals; Behavior, Animal; *Cognition; Heat; Helplessness, Learned; Housing, Animal/standards; Immobilization; Nesting Behavior; Pain/psychology/veterinary
	Abstract	To describe and then fulfill agricultural animals' needs, we must learn more about their fundamental psychological and behavioral processes. How does this animal feel? Is that animal suffering? Will we ever be able to know these things? Scientists specializing in animal cognition say that there are numerous problems but that they can be overcome. Recognition by scientists of the notion of animal awareness has been increasing in recent years, because of the work of Griffin and others. Feeling, thinking, remembering, and imagining are cognitive processes that are factors in the economic and humane production of agricultural animals. It has been observed that the animal welfare debate depends on two controversial questions: Do animals have subjective feelings? If they do, can we find indicators that reveal them? Here, indirect behavioral analysis approaches must be taken. Moreover, the linear additivity of several stressor effects on a variety of animal traits suggests that some single phenomenon is acting as a “clearinghouse” for many or all of the stresses acting on an animal at any given time, and this phenomenon might be psychological stress. Specific situations animals may encounter in agricultural production settings are discussed with respect to the animals' subjective feelings.

	Title	Do animals have cognitive maps?			Type	Journal Article
	Year	1996	Publication	The Journal of Experimental Biology	Abbreviated Journal	J Exp Biol
	Volume	199	Issue	Pt 1	Pages	219-224
	Keywords	Animals; Cognition/physiology; Humans; Space Perception/physiology; Visual Pathways
	Abstract	Drawing on studies of humans, rodents, birds and arthropods, I show that 'cognitive maps' have been used to describe a wide variety of spatial concepts. There are, however, two main definitions. One, sensu Tolman, O'Keefe and Nadel, is that a cognitive map is a powerful memory of landmarks which allows novel short-cutting to occur. The other, sensu Gallistel, is that a cognitive map is any representation of space held by an animal. Other definitions with quite different meanings are also summarised. I argue that no animal has been conclusively shown to have a cognitive map, sensu Tolman, O'Keefe and Nadel, because simpler explanations of the crucial novel short-cutting results are invariably possible. Owing to the repeated inability of experimenters to eliminate these simpler explanations over at least 15 years, and the confusion caused by the numerous contradictory definitions of a cognitive map, I argue that the cognitive map is no longer a useful hypothesis for elucidating the spatial behaviour of animals and that use of the term should be avoided.

	Title	Computations on metric maps in mammals: getting oriented and choosing a multi-destination route			Type	Journal Article
	Year	1996	Publication	The Journal of Experimental Biology	Abbreviated Journal	J Exp Biol
	Volume	199	Issue	Pt 1	Pages	211-217
	Keywords	Animals; Brain/physiology; Cercopithecus aethiops; Cognition/physiology; Humans; Mammals/physiology; Movement; Orientation/physiology; Rats; Space Perception; Visual Pathways/physiology
	Abstract	The capacity to construct a cognitive map is hypothesized to rest on two foundations: (1) dead reckoning (path integration); (2) the perception of the direction and distance of terrain features relative to the animal. A map may be constructed by combining these two sources of positional information, with the result that the positions of all terrain features are represented in the coordinate framework used for dead reckoning. When animals need to become reoriented in a mapped space, results from rats and human toddlers indicate that they focus exclusively on the shape of the perceived environment, ignoring non-geometric features such as surface colors. As a result, in a rectangular space, they are misoriented half the time even when the two ends of the space differ strikingly in their appearance. In searching for a hidden object after becoming reoriented, both kinds of subjects search on the basis of the object's mapped position in the space rather than on the basis of its relationship to a goal sign (e.g. a distinctive container or nearby marker), even though they have demonstrably noted the relationship between the goal and the goal sign. When choosing a multidestination foraging route, vervet monkeys look at least three destinations ahead, even though they are only capable of keeping a maximum of six destinations in mind at once.

	Title	Path integration in mammals and its interaction with visual landmarks			Type	Journal Article
	Year	1996	Publication	The Journal of Experimental Biology	Abbreviated Journal	J Exp Biol
	Volume	199	Issue	Pt 1	Pages	201-209
	Keywords	Animals; Cognition/physiology; Cricetinae; Gerbillinae; Humans; Locomotion/physiology; Mammals/physiology; Mesocricetus; Mice; Proprioception/physiology; Rats; Visual Pathways/physiology; Visual Perception/physiology
	Abstract	During locomotion, mammals update their position with respect to a fixed point of reference, such as their point of departure, by processing inertial cues, proprioceptive feedback and stored motor commands generated during locomotion. This so-called path integration system (dead reckoning) allows the animal to return to its home, or to a familiar feeding place, even when external cues are absent or novel. However, without the use of external cues, the path integration process leads to rapid accumulation of errors involving both the direction and distance of the goal. Therefore, even nocturnal species such as hamsters and mice rely more on previously learned visual references than on the path integration system when the two types of information are in conflict. Recent studies investigate the extent to which path integration and familiar visual cues cooperate to optimize the navigational performance.

	Title	Picture-object recognition in pigeons: evidence of representational insight in a visual categorization task using a complementary information procedure			Type	Journal Article
	Year	2006	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	2	Pages	190-195
	Keywords	Animals; Classification; Cognition; Columbidae; Discrimination Learning; Form Perception; Generalization (Psychology); Humans; Perceptual Closure; Photic Stimulation; Photography; *Recognition (Psychology)
	Abstract	Success in tasks requiring categorization of pictorial stimuli does not prove that a subject understands what the pictures stand for. The ability to achieve representational insight is by no means a trivial one because it exceeds mere detection of 2-D features present in both the pictorial images and their referents. So far, evidence for such an ability in nonhuman species is weak and inconclusive. Here, the authors report evidence of representational insight in pigeons. After being trained on pictures of incomplete human figures, the birds responded significantly more to pictures of the previously missing parts than to nonrepresentative stimuli, which demonstrates that they actually recognized the pictures' representational content.

	Title	Rhesus monkeys (Macaca mulatta) immediately generalize the uncertain response			Type	Journal Article
	Year	2006	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	2	Pages	185-189
	Keywords	Adaptation, Psychological; Animals; Cognition; Discrimination Learning; Generalization (Psychology); Macaca mulatta/psychology; Male; *Uncertainty
	Abstract	Rhesus monkeys (Macaca mulatta) have learned, like humans, to use an uncertain response adaptively under test conditions that create uncertainty, suggesting a metacognitive process by which human and nonhuman primates may monitor their confidence and alter their behavior accordingly. In this study, 4 rhesus monkeys generalized their use of the uncertain response, without additional training, to 2 familiar tasks (2-choice discrimination learning and mirror-image matching to sample) that predictably and demonstrably produce uncertainty. The monkeys were significantly less likely to use the uncertain response on trials in which the answer might be known. These results indicate that monkeys, like humans, know when they do not know and that they can learn to use a symbol as a generalized means for indicating their uncertainty.

	Title	The role of reference points in ordinal numerical comparisons by rhesus macaques (Macaca mulatta)			Type	Journal Article
	Year	2006	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	2	Pages	120-134
	Keywords	Animals; Cognition; Discrimination (Psychology); Generalization (Psychology); Macaca mulatta/psychology; Male; Mathematics; *Pattern Recognition, Visual
	Abstract	Two experiments examined ordinal numerical knowledge in rhesus macaques (Macaca mulatta). Experiment 1 replicated the finding (E. M. Brannon & H. S. Terrace, 2000) that monkeys trained to respond in descending numerical order (4-->3-->2-->1) did not generalize the descending rule to the novel values 5-9 in contrast to monkeys trained to respond in ascending order. Experiment 2 examined whether the failure to generalize a descending rule was due to the direction of the training sequence or to the specific values used in the training sequence. Results implicated 3 factors that characterize a monkey's numerical comparison process: Weber's law, knowledge of ordinal direction, and a comparison of each value in a test pair with the reference point established by the first value of the training sequence.

	Title	Rhesus macaques (Macaca mulatta) monitor uncertainty during numerosity judgments			Type	Journal Article
	Year	2006	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	2	Pages	111-119
	Keywords	Animals; Cognition; Judgment; Macaca mulatta/psychology; Male; Mathematics; Pattern Recognition, Visual; *Uncertainty
	Abstract	Two rhesus macaques (Macaca mulatta) judged arrays of dots on a computer screen as having more or fewer dots than a center value that was never presented in trials. After learning a center value, monkeys were given an uncertainty response that let them decline to make the numerosity judgment on that trial. Across center values (3-7), errors occurred most often for sets adjacent in numerosity to the center value. The monkeys also used the uncertainty response most frequently on these difficult trials. A 2nd experiment showed that monkeys' responses reflected numerical magnitude and not the surface-area illumination of the displays. This research shows that monkeys' uncertainty-monitoring capacity extends to the domain of numerical cognition. It also shows monkeys' use of the purest uncertainty response possible, uncontaminated by any secondary motivator.

	Title	Same/different abstract-concept learning by 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	1	Pages	80-86
	Keywords	Animals; Behavior, Animal; Cognition; Columbidae; Concept Formation; Conditioning (Psychology); *Learning
	Abstract	Eight pigeons were trained and tested in a simultaneous same/different task. After pecking an upper picture, they pecked a lower picture to indicate same or a white rectangle to indicate different. Increases in the training set size from 8 to 1,024 items produced improved transfer from 51.3% to 84.6%. This is the first evidence that pigeons can perform a two-item same/different task as accurately with novel items as training items and both above 80% correct. Fixed-set control groups ruled out training time or transfer testing as producing the high level of abstract-concept learning. Comparisons with similar experiments with rhesus and capuchin monkeys showed that the ability to learn the same/different abstract concept was similar but that pigeons require more training exemplars.
