	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	Group decision-making in animals			Type	Journal Article
	Year	2003	Publication	Nature	Abbreviated Journal	Nature
	Volume	421	Issue	6919	Pages	155-158
	Keywords	Animals; Behavior, Animal/physiology; Decision Making; Democracy; Group Processes; *Models, Biological; Population Density; Social Behavior
	Abstract	Groups of animals often need to make communal decisions, for example about which activities to perform, when to perform them and which direction to travel in; however, little is known about how they do so. Here, we model the fitness consequences of two possible decision-making mechanisms: 'despotism' and 'democracy'. We show that under most conditions, the costs to subordinate group members, and to the group as a whole, are considerably higher for despotic than for democratic decisions. Even when the despot is the most experienced group member, it only pays other members to accept its decision when group size is small and the difference in information is large. Democratic decisions are more beneficial primarily because they tend to produce less extreme decisions, rather than because each individual has an influence on the decision per se. Our model suggests that democracy should be widespread and makes quantitative, testable predictions about group decision-making in non-humans.

	Title	Use of leaves to inspect ectoparasites in wild chimpanzees: a third cultural variant?			Type	Journal Article
	Year	2004	Publication	Primates	Abbreviated Journal	Primates
	Volume	45	Issue	4	Pages	255-258
	Keywords	Animals; Animals, Wild/physiology; Ape Diseases/parasitology; Behavior, Animal/physiology; Ectoparasitic Infestations/parasitology/veterinary; Female; Grooming/physiology; Male; Pan troglodytes/physiology; Plant Leaves; Protozoa/*isolation & purification; Uganda
	Abstract	We report 26 cases of using leaves as tools with which wild chimpanzees (Pan troglodytes schweinfurthii) in the Sonso community, Budongo Forest, Uganda, appeared to inspect objects removed during grooming. Careful removal of potential ectoparasites and delicate lip or manual placement on leaves followed by intense visual examination characterised this behaviour. It appears to be done to judge whether either ingestion or discarding is most appropriate, the former occurring in most cases. This behaviour may represent a third variant of ectoparasite handling, different from those described at Tai and Gombe, yet sharing features with the latter. These two East African techniques may thus have evolved from leaf grooming.

	Title	*Interplay between environmental and genetic factors in temperament/personality traits in horses (Equus caballus)*			Type	Journal Article
	Year	2004	Publication	Journal of Comparative Psychology	Abbreviated Journal	J Comp Psychol
	Volume	118	Issue	4	Pages	434-446
	Keywords	Affect; Animals; Behavior, Animal/physiology; Environment; Female; Horses/psychology; Learning; Male; Memory/physiology
	Abstract	The aim of the present study was to broach the question of the relative influence of different genetic and environmental factors on different temperament/personality traits of horses (Equus caballus). The researchers submitted 702 horses to standardized experimental tests and investigated 9 factors, either genetic or environmental. Genetic factors, such as sire or breed, seemed to influence more neophobic reactions, whereas environmental factors, such as the type of work, seemed to play a more dominant role in reactions to social separation or learning abilities. Additive effects were evident, showing how environmental factors may modulate behavioral traits. This study constitutes a first step toward understanding the relative weights of genetic factors and how the environment may intervene in determining individual behavioral characteristics.

	Title	Distraction sneakers decrease the expected level of aggression within groups: a game-theoretic model			Type	Journal Article
	Year	2004	Publication	The American Naturalist	Abbreviated Journal	Am Nat
	Volume	164	Issue	2	Pages	E32-45
	Keywords	Aggression; Animals; Behavior, Animal/physiology; Columbidae/physiology; Competitive Behavior; Cooperative Behavior; Game Theory; Hawks/*physiology; Models, Biological
	Abstract	Hawk-dove games have been extensively used to predict the conditions under which group-living animals should defend their resources against potential usurpers. Typically, game-theoretic models on aggression consider that resource defense may entail energetic and injury costs. However, intruders may also take advantage of owners who are busy fighting to sneak access to unguarded resources, imposing thereby an additional cost on the use of the escalated hawk strategy. In this article we modify the two-strategy hawk-dove game into a three-strategy hawk-dove-sneaker game that incorporates a distraction-sneaking tactic, allowing us to explore its consequences on the expected level of aggression within groups. Our model predicts a lower proportion of hawks and hence lower frequencies of aggressive interactions within groups than do previous two-strategy hawk-dove games. The extent to which distraction sneakers decrease the frequency of aggression within groups, however, depends on whether they search only for opportunities to join resources uncovered by other group members or for both unchallenged resources and opportunities to usurp.

	Title	Animal cognition: defining the issues			Type	Journal Article
	Year	2004	Publication	Neuroscience and Biobehavioral Reviews	Abbreviated Journal	Neurosci Biobehav Rev
	Volume	28	Issue	7	Pages	645-650
	Keywords	Animals; Behavior, Animal/physiology; Cognition/physiology; Humans; *Models, Animal; Psychopharmacology/methods; Reproducibility of Results
	Abstract	The assessment of cognitive functions in rodents represents a critical experimental variable in many research fields, ranging from the basic cognitive neurosciences to psychopharmacology and neurotoxicology. The increasing use of animal behavioral tests as 'assays' for the assessment of effects on learning and memory has resulted in a considerable heterogeneity of data, particularly in the field of behavioral and psycho pharmacology. The limited predictive validity of changes in behavioral performance observed in standard animal tests of learning and memory indicates that a renewed effort to scrutinize the validity of these tests is warranted. In humans, levels of processing (effortful vs. automatic) and categories of information (procedural vs. episodic/declarative) are important variables of cognitive operations. The design of tasks that assess the recall of 'episodic' or 'declarative' information appears to represent a particular challenge for research using laboratory rodents. For example, the hypothesis that changes in inspection time for a previously encountered place or object are based on the recall of declarative/episodic information requires substantiation. In order to generalize findings on the effects of neuronal or pharmacological manipulations on learning and memory, obtained from one species and one task, to other species and other tasks, the mediating role of important sets of variables which influence learning and memory (e.g. attentional, affective) needs to be determined. Similar to the view that a neuronal manipulation (e.g. a lesion) represents a theory of the condition modeled (e.g. a degenerative disorder), an animal behavioral task represents a theory of the behavioral/cognitive process of interest. Therefore, the test of hypotheses regarding the validity of procedures used to assess cognitive functions in animals is an inherent part of the research process.

	Keywords	Animals; Chemoreceptors/physiology; Discrimination Learning/physiology; Embryo Implantation/physiology; Female; Individuality; Major Histocompatibility Complex/physiology; Male; Mice; Neurons, Afferent/physiology; Nose/cytology/physiology; Perception/physiology; Pregnancy; Pregnancy Maintenance/physiology; Pregnancy, Animal/physiology; Receptors, Odorant/physiology; Recognition (Psychology)/physiology; Sexual Behavior, Animal/physiology; Smell/physiology; Urine/physiology; Vomeronasal Organ/cytology/physiology
	Abstract	Individual recognition is an important component of behaviors, such as mate choice and maternal bonding that are vital for reproductive success. This article highlights recent developments in our understanding of the chemosensory cues and the neural pathways involved in individuality discrimination in rodents. There appear to be several types of chemosensory signal of individuality that are influenced by the highly polymorphic families of major histocompatibility complex (MHC) proteins or major urinary proteins (MUPs). Both have the capability of binding small molecules and may influence the individual profile of these chemosignals in biological fluids such as urine, skin secretions, or saliva. Moreover, these proteins, or peptides associated with them, can be taken up into the vomeronasal organ (VNO) where they can potentially interact directly with the vomeronasal receptors. This is particularly interesting given the expression of major histocompatibility complex Ib proteins by the V2R class of vomeronasal receptor and the highly selective responses of accessory olfactory bulb (AOB) mitral cells to strain identity. These findings are consistent with the role of the vomeronasal system in mediating individual discrimination that allows mate recognition in the context of the pregnancy block effect. This is hypothesized to involve a selective increase in the inhibitory control of mitral cells in the accessory olfactory bulb at the first level of processing of the vomeronasal stimulus.

	Title	A century of getting to know the chimpanzee			Type	Journal Article
	Year	2005	Publication	Nature	Abbreviated Journal	Nature
	Volume	437	Issue	7055	Pages	56-59
	Keywords	Aggression; Animals; Behavior, Animal/physiology; Competitive Behavior; Cooperative Behavior; Female; Humans; Male; Pan troglodytes/genetics/physiology/psychology; Sexual Behavior, Animal; *Social Behavior
	Abstract	A century of research on chimpanzees, both in their natural habitat and in captivity, has brought these apes socially, emotionally and mentally much closer to us. Parallels and homologues between chimpanzee and human behaviour range from tool-technology and cultural learning to power politics and intercommunity warfare. Few behavioural domains have remained untouched by this increased knowledge, which has dramatically challenged the way we view ourselves. The sequencing of the chimpanzee genome will no doubt bring more surprises and insights. Humans do occupy a special place among the primates, but this place increasingly has to be defined against a backdrop of substantial similarity.

	Title	Looking for inhibition of return in pigeons			Type	Journal Article
	Year	2005	Publication	Learning & behavior : a Psychonomic Society publication	Abbreviated Journal	Learn Behav
	Volume	33	Issue	3	Pages	296-308
	Keywords	Animals; Behavior, Animal/physiology; Columbidae; Inhibition (Psychology); Reinforcement (Psychology)
	Abstract	We conducted four experiments in order to investigate whether pigeons' responses to a recently attended (i.e., recently pecked) location are inhibited. In Experiments 1 and 2, stimulus displays were similar to those used in studies of inhibition of return (IOR) with humans; responses to cued targets tended to be facilitated rather than inhibited. In Experiments 3 and 4, birds were presented with stimulus displays that mimicked clusters of small grains and were relatively localized, which should have been more appropriate for detecting IOR in pigeons. The results from these experiments again provided evidence for facilitation of responding to cued targets, rather than for IOR.
