| Title | A Generalizability Analysis of Subjective Personality Assessments in the Stumptail Macaque and the Zebra Finch | Type | Journal Article | ||
| Year | 1995 | Publication | Multivariate Behavioral Research | Abbreviated Journal | Multivariate Behav Res |
| Volume | 30 | Issue | 2 | Pages | 167-197 |
| Keywords | |||||
| Abstract | Psychometric findings are reported from two studies concerning the construct validity, temporal stability, and interrater reliability of the latent common factors underlying subjective assessments by human raters of personality traits in two nonhuman animal species: (a) the Stumptail macaque (Maraca arctoides), a cercopithecine monkey; and (b) the Zebra finch (Poephila guttata), an estrildid songbird. Because most theories of animal personality have historically implied that certain personality constructs should be relatively universal across taxa, parallel analyses of similar data are reported for two phylogenetically distant species of subject using the same psychometric methods. Each of the samples was drawn from a socially-housed colony of the same species: that of macaques consisted of 5 mature adult fem ales and 8 of their adult offspring and that of finches consisted of 5 adult individuals. A modified version of the 1978 Stevenson-Hinde and Zunz (SHZ) list of personality items was applied to the macaques at various times during the eight years from 1980-1988 and to the finches during 1992. This study also used the three SHZ scales – Confident, Excitable, and Sociable – originally derived from principal components. Generalizability analyses were used to assess the construct validity, temporal stability, and interrater reliability of the hypothesized factors. Both Stumptail macaques and Zebra finches manifest measurable personality factors that are highly valid across multiple items, stable across multiple years, and reliable across multiple raters. The same model fits both species, as predicted by theory. The construct validity of the factors is slightly higher for the finches than for the macaques, although the interrater reliability is somewhat lower. This study illustrates how generalizability analysis can be used to test prespecified confirmatory factor models when the number of individual subjects is quite small. | ||||

| Title | Ecology and Behaviour of the African Buffalo: Social Inequality and Decision Making | Type | Book Whole | ||
| Year | 1995 | Publication | Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | What are the benefits that animals gain from living in a social group? This question has been the primary focus of the author's ecological interest. After many years of original and innovative research on the African buffalo, particularly at Lake Manyara in northern Tanzania, Herbert Prins has now summarized the results of much of this widely-respected work in this fascinating book. While advantages in reduction of the risks of predation or in increased efficiency of foraging on certain types of resources are now widely recognized, until now there has been less attention paid to the idea of the animals themselves as `information centres' and the extent to which the individual may be able to make use of information gathered by conspecifics, adjusting its own behaviour in response. Such a case-study has wide implications for research on social structure and organization in other species, and these are explored within the book. However, it is not a book aimed simply at the academic researcher, zoologist and behavioural ecologist; since it is written in a readable and accessible style, the book will also be enjoyed by wildlife enthusiasts, interested naturalists, wildlife biologists and wildlife managers. | ||||

| Abstract | Persistence of individual differences in animal behavior in reactions to various environmental challenges could reflect basic divergences in temperament, which might be used to predict details of adaptive response. Although studies have been carried out on fear and anxiety in various species, including laboratory, domestic and wild animals, no consistent definition of fearfulness as a basic trait of temperament has emerged. After a classification of the events that may produce a state of fear, this article describes the great variability in behavior and in physiological patterns generally associated with emotional reactivity. The difficulties of proposing fearfulness-the general capacity to react to a variety of potentially threatening situations-as a valid basic internal variable are then discussed. Although there are many studies showing covariation among the psychobiological responses to different environmental challenges, other studies find no such correlations and raise doubts about the interpretation of fearfulness as a basic personality trait. After a critical assessment of methodologies used in fear and anxiety studies, it is suggested that discrepancies among results are mainly due to the modulation of emotional responses in animals, which depend on numerous genetic and epigenetic factors. It is difficult to compare results obtained by different methods from animals reared under various conditions and with different genetic origins. The concept of fearfulness as an inner trait is best supported by two kinds of investigations. First, an experimental approach combining ethology and experimental psychology produces undeniable indicators of emotional reactivity. Second, genetic lines selected for psychobiological traits prove useful in establishing between behavioral and neuroendocrine aspects of emotional reactivity. It is suggested that fearfulness could be considered a basic feature of the temperament of each individual, one that predisposes it to respond similarly to a variety of potentially alarming challenges, but is nevertheless continually modulated during development by the interaction of genetic traits of reactivity with environmental factors, particularly in the juvenile period. Such interaction may explain much of the interindividual variability observed in adaptive responses. | ||||

| Title | The “migration” and grazing succession | Type | Book Chapter | ||
| Year | 1995 | Publication | Serengeti: Dynamics of an Ecosystem | Abbreviated Journal | |
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | Editorial Reviews Book Description Originally published in 1979, Serengeti: Dynamics of an Ecosystem was immediately recognized as the first synthesis of the patterns and processes of a major ecosystem. A prototype for initial studies, Serengeti contains baseline data for further and comparative studies of ecosystems. The new Serengeti II builds on the information presented originally in Serengeti; both books together offer essential information and insights for ecology and conservation biology. |

| Keywords | cross species imitative learning in problem solving, human 3–4 yr olds vs orangutans | ||||
| Abstract | Fourteen juvenile and adult orangutans and 24 3- and 4-yr-old children participated in 4 studies on imitative learning in a problem-solving situation. In all studies a simple to operate apparatus was used, but its internal mechanism was hidden from subjects to prevent individual learning. In the 1st study, orangutans observed a human demonstrator perform 1 of 4 actions on the apparatus and obtain a reward; they subsequently showed no signs of imitative learning. Similar results were obtained in a 2nd study in which orangutan demonstrators were used. Similar results were also obtained in a 3rd study in which a human encouraged imitation from an orangutan that had previously been taught to mimic arbitrary human actions. In a 4th study, human 3- and 4-yr-old children learned the task by means of imitation. (PsycINFO Database Record (c) 2010 APA, all rights reserved) | ||||
