Title	Chunking versus foraging search patterns by rats in the hierarchically baited radial maze			Type	Journal Article
Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
Volume	6	Issue	2	Pages	93-104
Keywords	Animals; Exploratory Behavior; Feeding Behavior; Male; Maze Learning; Rats; Rats, Long-Evans
Abstract	Rats were exposed to a radial maze containing six black smooth arms and six wire-grid-covered arms and a striped 'exit arm' in experiment 1. The probability of a black or grid arm being baited (5/6 vs 1/6) with sunflower seeds was associated with its proximal cue for some rats (the Relevant Arm Cue group) but not for others (the Irrelevant Arm Cue group). All rats could terminate a trial and receive a highly preferred morsel of apple by entering the exit arm only after having sampled all six seed-baited arms. Relevant Arm Cue rats usually chose some arms from the more densely baited set before choosing an arm from the less densely baited set and made fewer reentries than Irrelevant Arm Cue rats. Although such clustered, higher choice accuracy in the Relevant Arm Cue group corresponds to human clustered, better recall of verbal items from lists hierarchically organized by categories, these rats did not similarly exhaustively retrieve items (arm locations). That is, when required to terminate a trial by entering the 'exit' arm for an apple morsel after having sampled all seed-baited arms, both groups were equally unable to withhold making nonrewarded premature exits. This nonexhaustive foraging search pattern was maintained in the next two experiments in which the radial maze was reduced to three black and three grid arms along with the striped 'exit' arm and in which black and grid arm cues were paired with number of seeds (eight or one) in an arm for Relevant Arm Cue rats. Although Relevant Arm Cue rats displayed perfect clustering by entering all eight-seeded arms before a one-seeded arm, they made more premature exits and reentries into eight-seeded arms in experiment 2 or when forced to enter all eight-seeded arms in experiment 3 than did Irrelevant Arm Cue rats. These foraging tendencies prevent accurate estimations of the amount of information (i.e., arm locations) rats can 'chunk'.

Title	Social learning of food types in zebra finches (Taenopygia guttata) is directed by demonstrator sex and feeding activity			Type	Journal Article
Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
Volume	6	Issue	1	Pages	11-16
Keywords	Animals; Color; Diet; Feeding Behavior; Female; Learning; Male; Sex Factors; Social Behavior; Songbirds
Abstract	In this study we examined how social learning of feeding preferences by zebra finches was affected by the identity of different demonstrators. We presented adult zebra finches with two demonstrators, one male and one female, that exhibited different food choices, and we recorded their subsequent preference when given a choice between the two food types. Previously it was found that young zebra finches' patterns of social learning are affected by the sex of the individual demonstrating a feeding behaviour. This result could be explained by the lack of exposure these animals had to the opposite sex, or by their mating status. Therefore, we investigated the social learning preferences of adult mated zebra finches. We found the same pattern of directed social learning of a different type of feeding behaviour (food colour): female zebra finches preferred the colour of food eaten by male demonstrators, whereas male zebra finches showed little evidence of any preference for the colour of food eaten by female demonstrators. Furthermore, we found that female observers' preferences were biased by demonstrators' relative feeding activity: the female demonstrator was only ever preferred if it ate less than its male counterpart.

Title	Host preference of mosquito vectors of Japanese encephalitis			Type	Journal Article
Year	1975	Publication	Zhonghua Minguo wei Sheng wu xue za zhi = Chinese Journal of Microbiology	Abbreviated Journal	Zhonghua Min Guo Wei Sheng Wu Xue Za Zhi
Volume	8	Issue	4	Pages	274-279
Keywords	Animals; Behavior, Animal; Birds/blood; Culex; Ecology; Encephalitis, Japanese/transmission; Feeding Behavior; Female; Humans; *Insect Vectors; Mammals/blood; Species Specificity; Taiwan
Abstract	The host preference of 4 Culex mosquito species collected in Miaoli and Pingtung counties, Taiwan was studied by capillary precipitin method. Antisera to alum-precipitated sera of man, bovine, swine, rabbit, horse, dog, cat, mouse, chicken, duck, and pigeon were produced in rabbits and reacted with 758 mosquito blood meals among which reactions to one or more antisera. Culex annulus and Culex tritaeniorhynchus summorosus showed a great avidity for pig, and Culex fuscocephala for bovine. Culex pipiens fatigans was ornithophilic. None of 110 C. t. summorosus and 2.4% of 223 C. annulus had fed on man. Among 66 samples of C.p. fatigans tested 10.3% had fed on man, while none of 359 C. fuscocephala did. It seems that the latter does not act as a primary vector of Japanese encephalitis.

Title	Watching the best nutcrackers: what capuchin monkeys (Cebus apella) know about others' tool-using skills			Type	Journal Article
Year	2005	Publication	Animal cognition	Abbreviated Journal	Anim. Cogn.
Volume	8	Issue	4	Pages	215-219
Keywords	Animals; Association Learning; Cebus/psychology; Feeding Behavior; Female; Male; Nuts; Problem Solving
Abstract	The present work is part of a decade-long study on the spontaneous use of stones for cracking hard-shelled nuts by a semi-free-ranging group of brown capuchin monkeys (Cebus apella). Nutcracking events are frequently watched by other individuals--usually younger, less proficient, and that are well tolerated to the point of some scrounging being allowed by the nutcracker. Here we report findings showing that the choice of observational targets is an active, non-random process, and that observers seem to have some understanding of the relative proficiency of their group mates, preferentially watching the more skilled nutcrackers, which enhances not only scrounging payoffs, but also social learning opportunities.

Title	Testing for social learning and imitation in common marmosets, Callithrix jacchus, using an artificial fruit			Type	Journal Article
Year	2004	Publication	Animal cognition	Abbreviated Journal	Anim. Cogn.
Volume	7	Issue	2	Pages	77-85
Keywords	Animals; Association Learning; Callithrix/psychology; Discrimination Learning; Feeding Behavior; Female; Food Preferences; Fruit; Imitative Behavior; Male; *Social Behavior; Social Environment
Abstract	We tested for social learning and imitation in common marmosets using an artificial foraging task and trained conspecific demonstrators. We trained a demonstrator marmoset to open an artificial fruit, providing a full demonstration of the task to be learned. Another marmoset provided a partial demonstration, controlling for stimulus enhancement effects, by eating food from the outside of the apparatus. We thus compared three observer groups, each consisting of four animals: those that received the full demonstration, those that received the partial demonstration, and a control group that saw no demonstration prior to testing. Although none of the observer marmosets succeeded in opening the artificial fruit during the test periods, there were clear effects of demonstration type. Those that saw the full demonstration manipulated the apparatus more overall, whereas those from the control group manipulated it the least of the three groups. Those from the full-demonstration group also contacted the particular parts of the artificial fruit that they had seen touched (localised stimulus enhancement) to a greater extent than the other two groups. There was also an interaction between the number of hand and mouth touches made to the artificial fruit for the full- and partial-demonstration groups. Whether or not these data represent evidence for imitation is discussed. We also propose that the clear differences between the groups suggest that social learning mechanisms provide real benefits to these animals in terms of developing novel food-processing skills analogous to the one presented here.

Title	*Dynamic averaging and foraging decisions in horses (Equus callabus)*			Type	Journal Article
Year	2005	Publication	Journal of Comparative psychology	Abbreviated Journal	J. Comp. Psychol.
Volume	119	Issue	3	Pages	352-358
Keywords	Animals; Decision Making; Feeding Behavior; Female; Horses/psychology; Male; Memory, Short-Term; Motivation; Orientation; *Social Environment
Abstract	The variability of most environments taxes foraging decisions by increasing the uncertainty of the information available. One solution to the problem is to use dynamic averaging, as do some granivores and carnivores. Arguably, the same strategy could be useful for grazing herbivores, even though their food renews and is more homogeneously distributed. Horses (Equus callabus) were given choices between variable patches after short or long delays. When patch information was current, horses returned to the patch that was recently best, whereas those without current information matched choices to the long-term average values of the patches. These results demonstrate that a grazing species uses dynamic averaging and indicate that, like granivores and carnivores, they can use temporal weighting to optimize foraging decisions.

Title	Socially biased learning in monkeys			Type	Journal Article
Year	2004	Publication	Learning & behavior : a Psychonomic Society publication	Abbreviated Journal	Learn Behav
Volume	32	Issue	1	Pages	24-35
Keywords	Adaptation, Psychological; Animal Communication; Animals; Behavior, Animal; Feeding Behavior/psychology; Food Preferences/psychology; Haplorhini/psychology; Imitative Behavior; Imprinting (Psychology); Learning; Social Environment; Social Facilitation
Abstract	We review socially biased learning about food and problem solving in monkeys, relying especially on studies with tufted capuchin monkeys (Cebus apella) and callitrichid monkeys. Capuchin monkeys most effectively learn to solve a new problem when they can act jointly with an experienced partner in a socially tolerant setting and when the problem can be solved by direct action on an object or substrate, but they do not learn by imitation. Capuchin monkeys are motivated to eat foods, whether familiar or novel, when they are with others that are eating, regardless of what the others are eating. Thus, social bias in learning about foods is indirect and mediated by facilitation of feeding. In most respects, social biases in learning are similar in capuchins and callitrichids, except that callitrichids provide more specific behavioral cues to others about the availability and palatability of foods. Callitrichids generally are more tolerant toward group members and coordinate their activity in space and time more closely than capuchins do. These characteristics support stronger social biases in learning in callitrichids than in capuchins in some situations. On the other hand, callitrichids' more limited range of manipulative behaviors, greater neophobia, and greater sensitivity to the risk of predation restricts what these monkeys learn in comparison with capuchins. We suggest that socially biased learning is always the collective outcome of interacting physical, social, and individual factors, and that differences across populations and species in social bias in learning reflect variations in all these dimensions. Progress in understanding socially biased learning in nonhuman species will be aided by the development of appropriately detailed models of the richly interconnected processes affecting learning.

Title	A comparative study of culturally transmitted patterns of feeding habits in the chacma baboon Papio ursinus and the vervet monkey Cercopithecus aethiops			Type	Journal Article
Year	1981	Publication	Folia Primatologica; International Journal of Primatology	Abbreviated Journal	Folia Primatol (Basel)
Volume	36	Issue	3-4	Pages	243-263
Keywords	Age Factors; Animals; Cercopithecus; Cercopithecus aethiops; Culture; Feeding Behavior; Female; Group Structure; Learning; Male; Papio; Social Class; Teaching
Abstract	Japanese workers have studied social acquisition patterns of new feeding habits in Macaca fuscata which they have termed precultural. The present study investigates the same phenomenon in the chacma baboon and the vervet monkey in their natural habitat. The questions addressed are: (1) How a new feeding habit enters a troop and by which age and sex category, also how it is propagated? (2) When individuals are permitted with a choice between palatable and unpalatable food, can they learn by demonstration only or do they have to pass through a direct learning process? (3) Can the results from the above questions be explained by social parameters such as the social structure of the individual species? It was found that juvenile baboons discover new food and that after the discovery propagation is instantaneous. In vervets discovery is random among the age classes and propagation is slow and takes place through certain 'pivot' individuals. Both species fail to learn about palatability by demonstration but have to go through a direct learning process. This contrasts strongly with the forest baboon Mandrillus sphinx that have been shown to learn by demonstration. Socially, baboon juveniles stay closer to each other than the adults who force them to live at the periphery of the troop. Vervets again forage without precise sub-group formation. The link between social and cultural propagation and social structure is discussed on the basis of these findings.
