	Title	Quantifying motivation using a computer-controlled push-door			Type	Journal Article
	Year	1990	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	27	Issue	1	Pages	159-167
	Keywords
	Abstract	A computer-controlled push-door system was designed and tested as a method for measuring motivation. Eleven domestic hens were trained to use the push-door to gain access to food. They were deprived of food for 12 h or 43 h on 12 occasions and the push-door was used to measure the amount of “work” (measured as force × time) that they performed to gain access to a food reward. When deprived of food for 12 h the hens took significantly longer (P<0.01) to reach the required threshold of work, than when deprived for 43 h. This difference arose from the amount of time that the hens spent not pushing at the door. The problems encountered with this system and such an approach to measuring motivation are discussed.

	Title	The representation of social relations by monkeys			Type	Journal Article
	Year	1990	Publication	Cognition	Abbreviated Journal	Cognition
	Volume	37	Issue	1-2	Pages	167-196
	Keywords	Animals; Cercopithecus aethiops/psychology; Concept Formation; Dominance-Subordination; Female; Macaca fascicularis/psychology; Male; Social Behavior; *Social Environment
	Abstract	Monkeys recognize the social relations that exist among others in their group. They know who associates with whom, for example, and other animals' relative dominance ranks. In addition, monkeys appear to compare types of social relations and make same/different judgments about them. In captivity, longtailed macaques (Macaca fascicularis) trained to recognize the relation between one adult female and her offspring can identify the same relation among other mother-offspring pairs, and distinguish this relation from bonds between individuals who are related in a different way. In the wild, if a vervet monkey (Cercopithecus aethiops) has seen a fight between a member of its own family and a member of Family X, this increases the likelihood that it will act aggressively toward another member of Family X. Vervets act as if they recognize some similarity between their own close associates and the close associates of others. To make such comparisons the monkeys must have some way of representing the properties of social relationships. We discuss the adaptive value of such representations, the information they contain, their structure, and their limitations.

	Title	Variation in conformation of Swedish warmblood horses and conformational characteristics of elite sport horses			Type	Journal Article
	Year	1990	Publication	Equine Veterinary Journal	Abbreviated Journal	Equine Vet J
	Volume	22	Issue	3	Pages	186-193
	Keywords	Age Factors; Analysis of Variance; Animals; Breeding; Female; Forelimb/anatomy & histology; Hindlimb/anatomy & histology; Horses/anatomy & histology/physiology; Least-Squares Analysis; Male; Physical Conditioning, Animal; Regression Analysis; Sex Characteristics
	Abstract	The variation in conformation of 356 Swedish Warmblood horses is described, using a quantitative method of measuring horses. Thirty-three of the horses were elite dressage horses, 28 were elite showjumpers, 100 were riding school horses and 195 were unselected four-year-olds. Most horses had a long body form. The average height at the withers was 163.4 cm. Sixty per cent of the horses had a bench knee conformation, 50 per cent had a toe-in conformation of the forelimbs and 80 per cent had outwardly rotated hind limbs. The majority of these deviations were mild or moderate. Conformation was influenced by sex and age. Mares were smaller and had longer bodies and shorter limbs. The elite dressage horses and showjumpers had larger hock angles and more sloping scapulas than other horses. The showjumpers also had smaller fetlock angles in the front limbs. It is suggested that the larger hock angles among the elite horses may be because hocks with small angles are more prone to injury, and because small hock angles may negatively influence the ability to attain the degree of collection necessary for good performance in advanced classes.

	Title	Language capacities of nonhuman animals			Type	Journal Article
	Year	1990	Publication	American Journal of Physical Anthropology	Abbreviated Journal
	Volume	33	Issue	S11	Pages	215-243
	Keywords
	Abstract	In the last two decades, the study of language parallels in nonhuman animals has generated considerable controversy and excitement. Many have perceived demonstrations of linguistic skills in nonhuman animals as a threat to human uniqueness, whereas others have been uncritical of claims for complex cognitive skills in animals. Two different paradigms for studying linguistic parallels have appeared. One approach teaches great apes linguistic analogues of human language using signs or arbitrary symbol systems; the other seeks to decode communicative complexity in the natural languages of nonhuman animals. This paper reviews the language analogue studies with great apes and cetaceans, examining the utility of the different methods and reviewing the animals' accomplishments. Studies of ontogeny, syntax, referential communication, audience effects, and perception of vocalizations in the natural communication of birds, squirrels, and primates are evaluated. Finally, the brain mechanisms underlying human speech and language are compared with those involved in vocal communication in nonhuman primates. Although chimpanzees and bonobos have accomplished much, they do not threaten human uniqueness with respect to speech and language. Many of the claims for language paralleles in natural communication systems of nonhuman animals are weak, and many can be interpreted without recourse to cognitive constructs. Whereas there exist many similarities between subcortical controls of language and of animal vocalizations, there are no parallels to Broca's and Wernicke's areas in monkeys. However, the critical studies have not been done.

	Title	Neuroendocrine hemisphere asymmetries: Salivary cortisol secretion during lateralized viewing of emotion-related and neutral films			Type	Journal Article
	Year	1990	Publication	Brain and Cognition	Abbreviated Journal	Brain Cogn.
	Volume	14	Issue	2	Pages	243-265
	Keywords
	Abstract	The study set out to examine whether the cerebral hemispheres differ in their ability to regulate cortisol secretion during emotion-related situations. One hundred twenty-three adult subjects were shown either an emotionally aversive or a neutral film in the left or right hemisphere by means of a technique for lateralizing visual input that allows prolonged viewing while permitting free ocular scanning. The film-related changes of cortisol secretion were determined by salivary cortisol radioimmunoassay. Right hemispheric viewing of the emotionally aversive film resulted in a significantly higher increase of cortisol secretion than left hemispheric viewing of the same film. No such differences were observed with respect to the neutral film. Comparing the effects of the two films separately for each hemisphere revealed that only the right hemisphere was able to respond neuroendocrinologically in a different manner to the emotional and the neutral film. Therefore, it is concluded that cortical regulation of cortisol secretion in emotion-related situations is under primary control of the right hemisphere. The potential implications of asymmetric control of cortisol secretion with respect to the pathogenesis of psychosomatic and immunological disorders are discussed.

	Title	Could Mammalian Herbivores “Manage” Their Resources?			Type	Journal Article
	Year	1990	Publication	Oikos	Abbreviated Journal	Oikos
	Volume	59	Issue	2	Pages	270-280
	Keywords
	Abstract	The concept of resource management has gone hand in hand with group selection arguments. For this reason, it has been cast aside in the era of evolutionary theory which assumes that foraging strategies must have evolved under selection operating to maximise an individual's inclusive fitness. However, results from empirical studies show that under favourable environmental and social circumstances, resource management could be selectively advantageous. Much of the recent literature on plant-herbivore interactions suggest that herbivory can result in changes in the resource base which are assumed to increase the intake and fitness of the herbivore. As a result, a number of authors suggest that herbivores manage their resource utilisation to maximise the flow of nutrients from these resources. Long term territoriality or the exclusive use of a home range are the social systems most likely to favour selection for prudent resource exploitation. This review argues that, in many habitats, resource management strategies are not feasible, as individuals have little control over the way resources are depleted and renewed. Thus far, very little evidence is available showing that herbivorous mammals actively manage the resources which they utilise.
