Title Animal cooperation among unrelated individuals Type Journal Article
Year (up) 2002 Publication Die Naturwissenschaften Abbreviated Journal Naturwissenschaften
Volume 89 Issue 12 Pages 533-541
Keywords Animals; Phylogeny; *Social Behavior; Species Specificity
Abstract The evolution of cooperation has long been a topic near and dear to the hearts of behavioral and evolutionary ecologists. Cooperative behaviors run the gamut from fairly simple to very complicated and there are a myriad of ways to study cooperation. Here I shall focus on three paths that have been delineated in the study of intraspecific cooperation among unrelated individuals: reciprocity, byproduct mutualism, and group selection. In each case, I attempt to delineate the theory underlying each of these paths and then provide examples from the empirical literature. In addition, I shall briefly touch upon some recent work that has attempted to examine (or re-examine) the role of cognition and phylogeny in the study of cooperative behavior. While empirical and theoretical work has made significant strides in the name of better understanding the evolution and maintenance of cooperative behavior in animals, much work remains for the future. “From the point of view of the moralist, the animal world is on about the same level as the gladiator's show. The creatures are fairly well treated, and set to fight; whereby the strongest, the swiftest and the cunningest live to fight another day. The spectator has no need to turn his thumb down, as no quarter is given em leader the weakest and the stupidest went to the wall, while the toughest and the shrewdest, those who were best fitted to cope with their circumstances, but not the best in any other way, survived. Life was a continuous free fight, and em leader a war of each against all was the normal state of existence.” (Huxley 1888)

Title Dogs' (Canis familiaris) responsiveness to human pointing gestures Type Journal Article
Year (up) 2002 Publication Journal of Comparative Psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 116 Issue 1 Pages 27-34
Keywords Analysis of Variance; Animals; *Behavior, Animal; Choice Behavior; Dogs/*psychology; Female; Gestures; Male; *Recognition (Psychology); Species Specificity
Abstract In a series of 3 experiments, dogs (Canis familiaris) were presented with variations of the human pointing gesture: gestures with reversed direction of movement, cross-pointing, and different arm extensions. Dogs performed at above chance level if they could see the hand (and index finger) protruding from the human body contour. If these minimum requirements were not accessible, dogs still could rely on the body position of the signaler. The direction of movement of the pointing arm did not influence the performance. In summary, these observations suggest that dogs are able to rely on relatively novel gestural forms of the human communicative pointing gesture and that they are able to comprehend to some extent the referential nature of human pointing.

Title Matched concurrent case-control study of risk factors for feather pecking in hens on free-range commercial farms in the UK Type Journal Article
Year (up) 2003 Publication British poultry science Abbreviated Journal Br Poult Sci
Volume 44 Issue 4 Pages 515-523
Keywords *Aggression; Analysis of Variance; Animal Husbandry/methods; Animals; Case-Control Studies; Chickens/*physiology; Feathers; Female; Multivariate Analysis; Odds Ratio; Regression Analysis; Species Specificity
Abstract 1. The aim of the study was to compare the management and husbandry of free-range flocks in the UK where feather pecking was either present (case) or absent (control). 2. One hundred flocks were enrolled into a concurrent case-control study: 50 where birds had recently started feather pecking, and 50 matched control flocks where birds of the same age had not started feather pecking. 3. Information was obtained from a detailed interview with the flock manager, and by direct inspection of the flock, house and range. 4. Initial univariate analyses revealed that case flocks were more likely to comprise ISA Brown than Lohmann, were more likely to be restricted from litter areas to prevent floor eggs, and were less likely to use the outside range. 5. Cluster analysis indicated that feather pecking was not associated with any particular husbandry system. 6. The only influential risk factor significant in the multivariable conditional logistic regression analysis was use of the outdoor range. The risk of feather pecking was reduced 9-fold in flocks where more than 20% of birds used the range on sunny days (odds ratio = 0.12). Use of the range was positively associated with the presence of trees and/or hedges on the range.

Title Memory and hippocampal specialization in food-storing birds: challenges for research on comparative cognition Type Journal Article
Year (up) 2003 Publication Brain, behavior and evolution Abbreviated Journal Brain Behav Evol
Volume 62 Issue 2 Pages 108-116
Keywords Animals; Birds/*physiology; Cognition/*physiology; Color Perception/physiology; Feeding Behavior/*physiology; Hippocampus/*physiology; Memory/*physiology; Species Specificity
Abstract The three-way association among food-storing behavior, spatial memory, and hippocampal enlargement in some species of birds is widely cited as an example of a new 'cognitive ecology' or 'neuroecology.' Whether this relationship is as strong as it first appears and whether it might be evidence for an adaptive specialization of memory and hippocampus in food-storers have recently been the subject of some controversy [Bolhuis and Macphail, 2001; Macphail and Bolhuis, 2001]. These critiques are based on misconceptions about the nature of adaptive specializations in cognition, misconceptions about the uniformity of results to be expected from applying the comparative method to data from a wide range of species, and a narrow view of what kinds of cognitive adaptations are theoretically interesting. New analyses of why food-storers (black-capped chickadees, Poecile Atricapilla) respond preferentially to spatial over color cues when both are relevant in a memory task show that this reflects a relative superiority of spatial memory as compared to memory for color rather than exceptional spatial attention or spatial discrimination ability. New studies of chickadees from more or less harsh winter climates also support the adaptive specialization hypothesis and suggest that within-species comparisons may be especially valuable for unraveling details of the relationships among ecology, memory, and brain in food-storing species.

Title Signalers and receivers in animal communication Type Journal Article
Year (up) 2003 Publication Annual review of psychology Abbreviated Journal Annu Rev Psychol
Volume 54 Issue Pages 145-173
Keywords Affect; *Animal Communication; Animals; Arousal; Auditory Perception; Motivation; *Social Behavior; Social Environment; Species Specificity; *Vocalization, Animal
Abstract In animal communication natural selection favors callers who vocalize to affect the behavior of listeners and listeners who acquire information from vocalizations, using this information to represent their environment. The acquisition of information in the wild is similar to the learning that occurs in laboratory conditioning experiments. It also has some parallels with language. The dichotomous view that animal signals must be either referential or emotional is false, because they can easily be both: The mechanisms that cause a signaler to vocalize do not limit a listener's ability to extract information from the call. The inability of most animals to recognize the mental states of others distinguishes animal communication most clearly from human language. Whereas signalers may vocalize to change a listener's behavior, they do not call to inform others. Listeners acquire information from signalers who do not, in the human sense, intend to provide it.

Title Do humans ape? Or do apes human? Imitation and intention in humans (Homo sapiens) and other animals Type Journal Article
Year (up) 2003 Publication Journal of comparative psychology Abbreviated Journal J Comp Psychol
Volume 117 Issue 3 Pages 325-336
Keywords Adolescent; Adult; Animals; *Appetitive Behavior; Attention; Child, Preschool; Concept Formation; Female; Humans; *Imitative Behavior; Male; Motivation; Pan troglodytes/*psychology; *Problem Solving; *Psychomotor Performance; Reaction Time; Species Specificity
Abstract A. Whiten, D. M. Custance, J.-C. Gomez, P. Teixidor, and K. A. Bard (1996) tested chimpanzees' (Pan troglodytes) and human children's (Homo sapiens) skills at imitation with a 2-action test on an “artificial fruit.” Chimpanzees imitated to a restricted degree; children were more thoroughly imitative. Such results prompted some to assert that the difference in imitation indicates a difference in the subjects' understanding of the intentions of the demonstrator (M. Tomasello, 1996). In this experiment, 37 adult human subjects were tested with the artificial fruit. Far from being perfect imitators, the adults were less imitative than the children. These results cast doubt on the inference from imitative performance to an ability to understand others' intentions. The results also demonstrate how any test of imitation requires a control group and attention to the level of behavioral analysis.

Title Social learning by orangutans (Pongo abelii and Pongo pygmaeus) in a simulated food-processing task Type Journal Article
Year (up) 2003 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 117 Issue 3 Pages 272-282
Keywords *Animal Communication; Animals; *Feeding Behavior; Female; *Imitative Behavior; Male; Pongo pygmaeus/*psychology; Problem Solving; Psychomotor Performance; Social Environment; Species Specificity; *Transfer (Psychology)
Abstract Increasing evidence for behavioral differences between populations of primates has created a resurgence of interest in examining mechanisms of information transfer between individuals. The authors examined the social transmission of information in 15 captive orangutans (Pongo abelii and Pongo pygmaeus) using a simulated food-processing task. Experimental subjects were shown 1 of 2 methods for removing a suite of defenses on an “artificial fruit.” Control subjects were given no prior exposure before interacting with the fruit. Observing a model provided a functional advantage in the task, as significantly more experimental than control subjects opened the fruit. Within the experimental groups, the authors found a trend toward differences in the actual behaviors used to remove 1 of the defenses. Results support observations from the wild implying horizontal transfer of information in orangutans and show that a number of social learning processes are likely to be involved in the transfer of knowledge in this species.

Title Strategic navigation of two-dimensional alley mazes: comparing capuchin monkeys and chimpanzees Type Journal Article
Year (up) 2003 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 6 Issue 3 Pages 149-160
Keywords Animals; Cebus/*physiology; Choice Behavior/*physiology; Computer Peripherals; Female; Male; Maze Learning/*physiology; Neuropsychological Tests; Pan troglodytes/*physiology; Space Perception/*physiology; Species Specificity; User-Computer Interface
Abstract Planning is an important component of cognition that contributes, for example, to efficient movement through space. In the current study we presented novel two-dimensional alley mazes to four chimpanzees and three capuchin monkeys to identify the nature and efficiency of planning in relation to varying task parameters. All the subjects solved more mazes without error than expected by chance, providing compelling evidence that both species planned their choices in some manner. The probability of making a correct choice on mazes designed to be more demanding and presented later in the testing series was higher than on earlier, simpler mazes (chimpanzees), or unchanged (capuchin monkeys), suggesting microdevelopment of strategic choice. Structural properties of the mazes affected both species' choices. Capuchin monkeys were less likely than chimpanzees to take a correct path that initially led away from the goal but that eventually led to the goal. Chimpanzees were more likely to make an error by passing a correct path than by turning onto a wrong path. Chimpanzees and one capuchin made more errors on choices farther in sequence from the goal. Each species corrected errors before running into the end of an alley in approximately 40% of cases. Together, these findings suggest nascent planning abilities in each species, and the prospect for significant development of strategic planning capabilities on tasks presenting multiple simultaneous or sequential spatial relations. The computerized maze paradigm appears well suited to investigate movement planning and spatial perception in human and nonhuman primates alike.
