	Title	Social influences on the acquisition of tool-using behaviors in tufted capuchin monkeys (Cebus apella)			Type	Journal Article
	Year	1989	Publication	Journal of Comparative Psychology	Abbreviated Journal	J. Comp. Psychol.
	Volume	103	Issue	2	Pages	159-170
	Keywords
	Abstract	To identify behaviors related to acquisition of tool-use in tufted capuchins (Cebus apella), we presented two tool-using tasks to two groups, extending findings by Westergaard and Fragaszy (1987) and Visalberghi (in press). Five Ss learned to use the tools in each task. The primary predictor of success was level of interest in the task. Observation of others at the apparatus did not facilitate exploratory behaviors or contact with the tools in the observers. Most animals performed exploratory behaviors more often when they were at the apparatus alone than when with another, whether or not the other was using a tool. Observers were quick to learn the relationship between another's activities and the appearance of food. We conclude that capuchins do not readily learn about instrumental relations by observation of others or imitate other's acts. Imitation probably plays no role in the spread of novel instrumental behaviors among monkeys. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

	Author	Visalberghi E; Trinca L
	Title	Tool use in capuchin monkeys: distinguishing between performing and understanding			Type	Journal Article
	Year	1989	Publication	Primates	Abbreviated Journal	Primates
	Volume	30	Issue		Pages	511
	Keywords	Tool use – Cebus apella – Mental representation
	Abstract	A horizontal plexiglas tube containing a food-reward was presented to four naive tufted capuchins and suitable sticks were provided to push the reward out. Three monkeys out of four spontaneously used the tools and showed very different styles of solving the task. In more complex conditions, in which the sticks needed to be combined or actively modified in order to become effective, the monkeys were always successful; however, their performance was loaded with errors which did not disappear throughout the trials. Evidence of a difference between success in solving the problem and its understanding was found. This suggests that although capuchins can discover new means through active experimentation, they do not mentally represent the characteristics necessary for a tool to be effective, nor do they modify the tool appropriately beforehand. At this level, a major difference with chimpanzees emerges.

	Title	The effect of body condition of horses on discrimination learning abilities			Type	Journal Article
	Year	1989	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	22	Issue	3-4	Pages	327-334
	Keywords
	Abstract	Discriminative learning abilities were studied in 12 mature, malnourished horses. All horses initially received a condition score (CS) between 2 and 4 on a scale of 1 (poor) to 9 (extremely fat). Then horses were assigned to one of 3 treatments based on their eventual, rehabilitated CS during discrimination testing: thin, CS 1-3; moderate, CS 4-6; and fat, CS 7-9. The discrimination learning task was performed for 14 days with a maximum of 20 trials per day. Daily criterion was set at eight consecutively correct trails. Total trials to first criteria and total errors during testing were recorded. Analysis of variance showed that treatments did not differ (P>0.05) in total trials to first criterion, however horses on the fat treatment did have higher total error scores (P<0.05) than horses on the thin or moderate treatments. This difference was probably owing to lack of motivation in the fat treatment horses, rather than to true learning ability differences. The sex of the horse did not significantly affect either learning score.

	Title	Group foraging, public information, and patch estimation			Type	Journal Article
	Year	1989	Publication	Oikos	Abbreviated Journal	Oikos
	Volume	56	Issue	3	Pages	357-363
	Keywords	Techniques; Mathematical techniques; Nutrition; Feeding behaviour; Behaviour; Social behaviour^, Comprehensive Zoology; Mathematical model; Resource patch estimation by group members; use of public information; Foraging; Group behaviour
	Abstract	Public information is information about the quality of a patch that can be obtained by observing the foraging success of other individuals in that patch. I examine the influence of the use of public information on patch departure and foraging efficiency of group members. When groups depart a patch with the first individual to leave, the use of public information can prevent the underutilization of resource patches.

	Title	Generalized linear models.			Type	Book Whole
	Year	1989	Publication		Abbreviated Journal
	Volume		Issue		Pages
	Keywords
	Abstract	Book Description The success of the first edition of Generalized Linear Models led to the updated Second Edition, which continues to provide a definitive unified, treatment of methods for the analysis of diverse types of data. Today, it remains popular for its clarity, richness of content and direct relevance to agricultural, biological, health, engineering, and other applications. The authors focus on examining the way a response variable depends on a combination of explanatory variables, treatment, and classification variables. They give particular emphasis to the important case where the dependence occurs through some unknown, linear combination of the explanatory variables. The Second Edition includes topics added to the core of the first edition, including conditional and marginal likelihood methods, estimating equations, and models for dispersion effects and components of dispersion. The discussion of other topics-log-linear and related models, log odds-ratio regression models, multinomial response models, inverse linear and related models, quasi-likelihood functions, and model checking-was expanded and incorporates significant revisions. Comprehension of the material requires simply a knowledge of matrix theory and the basic ideas of probability theory, but for the most part, the book is self-contained. Therefore, with its worked examples, plentiful exercises, and topics of direct use to researchers in many disciplines, Generalized Linear Models serves as ideal text, self-study guide, and reference.

	Title	Feralization: The making of wild domestic animals			Type	Journal Article
	Year	1989	Publication	Behavioural Processes	Abbreviated Journal	Behav. Process.
	Volume	19	Issue	1-3	Pages	79-94
	Keywords	feralization; domestication; feral dogs
	Abstract	The widely accepted viewpoint that feralization is the reverse of domestication requires that the feralization process be restricted to populations of animals and, therefore, cannot occur in individuals. An alternative, ontogenetic approach is presented in which feralization is defined as the process by which individual domestic animals either become desocialized from humans, or never become socialized, and thus behave as untamed, non-domestic animals. Feralization will vary among species and, intraspecifically, will depend upon an individual's age and history of socialization to humans. Because feralization is not equated with morphological change resulting from evolutionary processes, species formation is not an accurate indicator of feral condition.

	Title	The effect of group size and space allowance on the agonistic and spacing behavior of cattle			Type	Journal Article
	Year	1989	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	24	Issue	2	Pages	127-135
	Keywords
	Abstract	The number of agonistic encounters in a group (frequency per h) and the mean distance to the nearest neighbor in a group (m) were analyzed by a multiple regression on the group size (number of animals in a group) and space allowance (m3 per animal) in each group of calves (6–13 months old, Holstein female and castrated male) and adult cattle (2–12 years old, Holstein heifers and cows or Holstein and Hereford grazing beef cattle). A total of 196 calves and 602 adult animals were used in this analysis. In calves, a significant correlation was found between agonistic behavior and space allowance (r=-0.48, P<0.01), but not between agonistic behavior and group sizes. The mean distance to the nearest neighbor in calf groups increased as the group size decreased and space allowance increased (R2=0.66, P<0.01). In adult cattle, the number of agonistic encounters increased linearly as the group size increased (r=+0.37, P<0.05). The relationship between agonistic behavior and 1(space allowance)2 was significant (r=+0.48, P<0.05). The mean distance to the nearest neighbor tended to increase as the group size decreased and the space allowance increased (R2=0.68, P<0.01). When the space allowance increased beyond 360 m2 per animal, the average distance to the nearest neighbor in the adult group was maintained within the range of 10–12 m.
