	Title	Imitation recognition in a captive chimpanzee (Pan troglodytes)			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	1	Pages	31-36
	Keywords	Animals; Awareness; Humans; Imitative Behavior; Male; Motor Activity; Movement; Pan troglodytes/psychology; *Recognition (Psychology)
	Abstract	This study investigated the ability of a captive chimpanzee (Pan troglodytes) to recognise when he is being imitated. In the experimental condition of test 1a, an experimenter imitated the postures and behaviours of the chimpanzee as they were being displayed. In three control conditions the same experimenter exhibited (1) actions that were contingent on, but different from, the actions of the chimpanzee, (2) actions that were not contingent on, and different from, the actions of the chimpanzee, or (3) no action at all. The chimpanzee showed more “testing” sequences (i.e., systematically varying his actions while oriented to the imitating experimenter) and more repetitive behaviour when he was being imitated, than when he was not. This finding was replicated 4 months later in test 1b. When the experimenter repeated the same actions she displayed in the experimental condition of test 1a back to the chimpanzee in test 2, these actions now did not elicit those same testing sequences or repetitive behaviours. However, a live imitation condition did. Together these results provide the first evidence of imitation recognition in a nonhuman animal.

	Title	Nuns and monkeys: investigating the behavior of our oldest old			Type	Journal Article
	Year	2004	Publication	Science of Aging Knowledge Environment : SAGE KE	Abbreviated Journal	Sci Aging Knowledge Environ
	Volume	2004	Issue	41	Pages	pe38
	Keywords	Aged; Aged, 80 and over/physiology; Aging/physiology; Animals; Behavior/*physiology; Humans; Macaca mulatta
	Abstract	The use of nonhuman primates, particularly rhesus macaques (Macaca mulatta), as the best model for human physiological and cognitive aging is broadly accepted. Studies employing nonhuman primates to investigate behavioral changes that may occur with increasing age, however, are not common mostly because of the unavailability of appropriate subjects. Recent longitudinal human studies suggest that individual personality might play a large role in aging “successfully” and in the retention of high levels of cognition into old age. As a result of the demographic trend of increasing numbers of aged monkeys and apes in captivity, an opportunity exists to further investigate behavioral aging using the monkey model.

	Title	Copying results and copying actions in the process of social learning: chimpanzees (Pan troglodytes) and human children (Homo sapiens)			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	3	Pages	151-163
	Keywords	Animals; Child Behavior; Child, Preschool; Concept Formation; Female; Humans; Imitative Behavior; Learning; Male; Pan troglodytes; Problem Solving; Psychomotor Performance; Random Allocation; *Social Environment; Species Specificity
	Abstract	There is currently much debate about the nature of social learning in chimpanzees. The main question is whether they can copy others' actions, as opposed to reproducing the environmental effects of these actions using their own preexisting behavioral strategies. In the current study, chimpanzees (Pan troglodytes) and human children (Homo sapiens) were shown different demonstrations of how to open a tube-in both cases by a conspecific. In different experimental conditions, demonstrations consisted of (1) action only (the actions necessary to open the tube without actually opening it); (2) end state only (the open tube, without showing any actions); (3) both of these components (in a full demonstration); or (4) neither of these components (in a baseline condition). In the first three conditions subjects saw one of two different ways that the tube could open (break in middle; caps off ends). Subjects' behavior in each condition was assessed for how often they opened the tube, how often they opened it in the same location as the demonstrator, and how often they copied the demonstrator's actions or style of opening the tube. Whereas chimpanzees reproduced mainly the environmental results of the demonstrations (emulation), human children often reproduced the demonstrator's actions (imitation). Because the procedure used was similar in many ways to the procedure that Meltzoff (Dev Psych 31:1, 1995) used to study the understanding of others' unfulfilled intentions, the implications of these findings with regard to chimpanzees' understanding of others' intentions are also discussed.

	Title	Effects of information and group structure on evolution of altruism: analysis of two-score model by covariance and contextual analyses			Type	Journal Article
	Year	2005	Publication	Journal of theoretical biology	Abbreviated Journal	J. Theor. Biol.
	Volume	232	Issue	2	Pages	191-201
	Keywords	Altruism; Analysis of Variance; Communication; Cooperative Behavior; Evolution; Game Theory; Group Structure; Humans; Models, Genetic; Models, Psychological; Selection (Genetics); Trust
	Abstract	An altruistic individual has to gamble on cooperation to a stranger because it does not know whether the stranger is trustworthy before direct interaction. Nowak and Sigmund (Nature 393 (1998a) 573; J. Theor. Biol. 194 (1998b) 561) presented a new theoretical framework of indirect reciprocal altruism by image scoring game where all individuals are informed about a partner's behavior from its image score without direct interaction. Interestingly, in a simplified version of the image scoring game, the evolutionarily stability condition for altruism became a similar form of Hamilton's rule, i.e. inequality that the probability of getting correct information is more than the ratio of cost to benefit. Since the Hamilton's rule was derived by evolutionarily stable analysis, the evolutionary meaning of the probability of getting correct information has not been clearly examined in terms of kin and group selection. In this study, we applied covariance analysis to the two-score model for deriving the Hamilton's rule. We confirmed that the probability of getting correct information was proportional to the bias of altruistic interactions caused by using information about a partner's image score. The Hamilton's rule was dependent on the number of game bouts even though the information reduced the risk of cooperation to selfish one at the first encounter. In addition, we incorporated group structure to the two-score model to examine whether the probability of getting correct information affect selection for altruism by group selection. We calculated a Hamilton's rule of group selection by contextual analysis. Group selection is very effective when either the probability of getting correct information or that of future interaction, or both are low. The two Hamilton's rules derived by covariance and contextual analyses demonstrated the effects of information and group structure on the evolution of altruism. We inferred that information about a partner's behavior and group structure can produce flexible pathways for the evolution of altruism.

	Title	Causal knowledge and imitation/emulation switching in chimpanzees (Pan troglodytes) and children (Homo sapiens)			Type	Journal Article
	Year	2005	Publication	Animal cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	3	Pages	164-181
	Keywords	Animals; Child Behavior; Child, Preschool; Concept Formation; Female; Humans; Imitative Behavior; Learning; Male; Pan troglodytes; Problem Solving; Psychomotor Performance; *Social Environment; Species Specificity
	Abstract	This study explored whether the tendency of chimpanzees and children to use emulation or imitation to solve a tool-using task was a response to the availability of causal information. Young wild-born chimpanzees from an African sanctuary and 3- to 4-year-old children observed a human demonstrator use a tool to retrieve a reward from a puzzle-box. The demonstration involved both causally relevant and irrelevant actions, and the box was presented in each of two conditions: opaque and clear. In the opaque condition, causal information about the effect of the tool inside the box was not available, and hence it was impossible to differentiate between the relevant and irrelevant parts of the demonstration. However, in the clear condition causal information was available, and subjects could potentially determine which actions were necessary. When chimpanzees were presented with the opaque box, they reproduced both the relevant and irrelevant actions, thus imitating the overall structure of the task. When the box was presented in the clear condition they instead ignored the irrelevant actions in favour of a more efficient, emulative technique. These results suggest that emulation is the favoured strategy of chimpanzees when sufficient causal information is available. However, if such information is not available, chimpanzees are prone to employ a more comprehensive copy of an observed action. In contrast to the chimpanzees, children employed imitation to solve the task in both conditions, at the expense of efficiency. We suggest that the difference in performance of chimpanzees and children may be due to a greater susceptibility of children to cultural conventions, perhaps combined with a differential focus on the results, actions and goals of the demonstrator.

	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.

	Title	Conditioning and cognition			Type	Journal Article
	Year	2004	Publication	Neuroscience and Biobehavioral Reviews	Abbreviated Journal	Neurosci Biobehav Rev
	Volume	28	Issue	7	Pages	651-661
	Keywords	Animals; Association Learning/physiology; Cognition/physiology; Conditioning (Psychology)/physiology; Discrimination Learning/physiology; Humans; Memory; Models, Psychological; Reinforcement (Psychology); Visual Perception/physiology
	Abstract	Animals' abilities to use internal representations of absent objects to guide adaptive behavior and acquire new information, and to represent multiple spatial, temporal, and object properties of complex events and event sequences, may underlie many aspects of human perception, memory, and symbolic thought. In this review, two classes of simple associative learning tasks that address these core cognitive capacities are discussed. The first set, including reinforcer revaluation and mediated learning procedures, address the power of Pavlovian conditioned stimuli to gain access, through learning, to representations of upcoming events. The second set of investigations concern the construction of complex stimulus representations, as illustrated in studies of contextual learning, the conjunction of explicit stimulus elements in configural learning procedures, and recent studies of episodic-like memory. The importance of identifying both cognitive process and brain system bases of performance in animal models is emphasized.

	Title	Reinforced variability in animals and people: implications for adaptive action			Type	Journal Article
	Year	2004	Publication	The American Psychologist	Abbreviated Journal	Am Psychol
	Volume	59	Issue	9	Pages	891-906
	Keywords	Animals; Behavior, Animal; Choice Behavior; Conditioning, Operant; Creativeness; Discrimination (Psychology); Humans; Memory; Problem Solving; Reinforcement (Psychology)
	Abstract	Although reinforcement often leads to repetitive, even stereotyped responding, that is not a necessary outcome. When it depends on variations, reinforcement results in responding that is diverse, novel, indeed unpredictable, with distributions sometimes approaching those of a random process. This article reviews evidence for the powerful and precise control by reinforcement over behavioral variability, evidence obtained from human and animal-model studies, and implications of such control. For example, reinforcement of variability facilitates learning of complex new responses, aids problem solving, and may contribute to creativity. Depression and autism are characterized by abnormally repetitive behaviors, but individuals afflicted with such psychopathologies can learn to vary their behaviors when reinforced for so doing. And reinforced variability may help to solve a basic puzzle concerning the nature of voluntary action.

	Title	Individual variation by self-organisation			Type	Journal Article
	Year	2005	Publication	Neuroscience and biobehavioral reviews	Abbreviated Journal	Neurosci Biobehav Rev
	Volume	29	Issue	1	Pages	125-136
	Keywords	Aggression; Animals; Behavior, Animal/physiology; Competitive Behavior/physiology; Female; Humans; Individuality; Male; Models, Psychological; Sex Characteristics; Social Dominance; Time Factors
	Abstract	In this paper, we show that differences in dominance and spatial centrality of individuals in a group may arise through self-organisation. Our instrument is a model, called DomWorld, that represents two traits that are often found in animals, namely grouping and competing. In this model individual differences grow under the following conditions: (1) when the intensity of aggression increases and grouping becomes denser, (2) when the degree of sexual dimorphism in fighting power increases. In this case the differences among females compared to males grow too, (3) when, upon encountering another individual, the tendency to attack is 'obligate' and not conditional, namely 'sensitive to risks'. Results resemble phenomena described for societies of primates, mice, birds and pigs.
