Title | Experimental tests to assess emotionality in horses | Type | Journal Article | ||
Year | 1997 | Publication | Behavioural Processes | Abbreviated Journal | Behav. Process. |
Volume | 40 | Issue | 3 | Pages | 209-221 |
Keywords | Emotivity; Gregariousness; Horse; Neophobia; Open-field | ||||
Abstract | Different tests were used to assess different aspects of the emotionality of 1-3 year-old horses: arena test; a [`]novel object' test; and a handling test. In reaction to the test situations no important differences were observed according to age or sex in the behaviour patterns, but clear individual differences were observed within these classes. The arena test seemed to reveal the degree of gregariousness of the animals whereas the results in the two other tests were correlated and seemed to reflect an inherent degree of fearfulness in the horse. Indices were developed that enabled to rank the animals, by taking into account all behaviour patterns shown. Such individual characteristics might have some genetic basis: half-siblings tended to behave the same way in most cases. | ||||

Title | The science of animal cognition: past, present, and future | Type | Journal Article | ||
Year | 1997 | Publication | Journal of Experimental Psychology. Animal Behavior Processes | Abbreviated Journal | J Exp Psychol Anim Behav Process |
Volume | 23 | Issue | 2 | Pages | 123-135 |
Keywords | Animal Communication; Animal Population Groups/*psychology; Animals; Behavior, Animal; Behavioral Sciences/*trends; *Cognition; Evolution; Forecasting; Humans; Intelligence | ||||
Abstract | The field of animal cognition is strongly rooted in the philosophy of mind and in the theory of evolution. Despite these strong roots, work during the most famous and active period in the history of our science-the 1930s, 1940s, and 1950s-may have diverted us from the very questions that were of greatest initial interest to the comparative analysis of learning and behavior. Subsequently, the field has been in steady decline despite its increasing breadth and sophistication. Renewal of the field of animal cognition may require a return to the original questions of animal communication and intelligence using the most advanced tools of modern psychological science. Reclaiming center stage in contemporary psychology will be difficult; planning that effort with a host of strategies should enhance the chances of success. | ||||

Title | Primate Cognition | Type | Book Whole | ||
Year | 1997 | Publication | Oxford University Press | Abbreviated Journal | Oxf. Univ. Pr. |
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | Description Ever since Charles Darwin first formulated his theories on evolution, much research has been conducted in primate cognition. In this book, Michael Tomasello and Josep Call review what is already known about the cognitive skills of nonhuman primates, and assess the current state of our knowledge. They integrate empirical findings on the topic from the beginning of the century to the present, placing this work in theoretical perspective. The first part examines the way primates adapt to their physical world, mostly for the purpose of foraging. The second part lokos at primate social knowledhe and focuses on the adaptations of primates to their social world for purposes of competation and cooperation. In the third section, the authors construct a general theory of primate cognition, distinguishing the cognition in primates from that of other mammals (human in particular). Their broad-ranging theory should provide a guide for future research. Primate Cognition is an enlightening exploration of the cognitive capacities of our nearest primate relatives. It is a useful resource for a eide range of researchers and students in psychology, behavioral biology, primatology, and anthropology. |

Title | Evaluation of false ultrasonographic pregnancy diagnoses in sows by measuring the concentration of unconjugated estrogens in feces | Type | Journal Article | ||
Year | 1997 | Publication | Theriogenology | Abbreviated Journal | Theriogenology |
Volume | 48 | Issue | 5 | Pages | 873-882 |
Keywords | |||||
Abstract | On Days 26, 28, and 30 after AI, ultrasonographic pregnancy diagnoses were performed on 207 gilts and sows by using a 3.5 MHz linear-array transducer. Fecal samples were taken from the rectum after each ultrasonographic examination, and the concentrations of unconjugated estrogens in selected samples (n = 73) were measured by RIA. Fecal unconjugated estrogen concentration of 11.7 ng/g feces or higher was indicative of pregnancy. The overall sensitivity and specificity of the ultrasonographic test was 99% for farrowing sows and 73.1% for nonfarrowing sows. With one exception, sows with a false negative diagnosis by ultrasonography on Day 26 were correctly diagnosed pregnant by elevated fecal unconjugated estrogens or repeated ultrasonographic examinations on Days 28 or 30. Return to estrus around the sampling period may cause false positive results in the unconjugated estrogen assay, while early embryonic mortality can result in false positive diagnoses in both the ultrasonographic test and estrogen assay. Although there was a positive correlation between the concentrations of unconjugated estrogens in the feces and litter size at farrowing in the selected sows, it seems very unlikely that fecal estrogens can provide an accurate tool for predicting litter size. | ||||

Title | The evolution of female social relationships in nonhuman primates | Type | Journal Article | ||
Year | 1997 | Publication | Behavioral Ecology and Sociobiology | Abbreviated Journal | Behav. Ecol. Sociobiol. |

Abstract | Considerable interspeci®c variation in female social relationships occurs in gregarious primates, particularly with regard to agonism and cooperation between females and to the quality of female relationships with males. This variation exists alongside variation in female philopatry and dispersal. Socioecological theories have tried to explain variation in female-female social relationships from an evolutionary perspective focused on ecological factors, notably predation and food distribution. According to the current ``ecological model'', predation risk forces females of most diurnal primate species to live in groups; the strength of the contest component of competition for resources within and between groups then largely determines social relationships between females. Social elationships among gregarious females are here characterized as DispersalEgalitarian, Resident-Nepotistic, Resident-Nepotistic-Tolerant, or Resident-Egalitarian. This ecological model has successfully explained i€erences in the occurrence of formal submission signals, decided dominance relation ships, coalitions and female philopatry. Group size and female rank generally a€ect female reproduction success as the model predicts, and studies of closely related species in di€erent ecological circumstances underscore the importance of the model. Some cases, however, can only be explained when we extend the model to incorporate the e€ects of infanticide risk and habitat saturation. We review evidence in support of the ecological model and test the power of alternative models that invoke between-group competition, forced female philopatry, demographic female recruitment, male interventions into female aggression, and male harassment. Not one of these models can replace the ecological model, which already encompasses the between-group competition. Currently the best model, which explains several phenomena that the ecological model does not, is a ``socioecological model'' based on the combined importance of ecological factors, habitat saturation and infanticide avoidance. We note some points of similarity and divergence with other mammalian taxa; these remain to be explored in detail. |
