  Title Feeding competition between grazing red deer hinds Type Journal Article
  Year 1990 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 40 Issue 1 Pages (down) 105-111  
  Keywords  
  Abstract The effect of social rank on the feeding behaviour of female red deer, Cervus elaphus L., on the Isle of Rhum, Scotland, was investigated. Hinds were less likely to approach and more likely to leave the vicinity of other individuals if these hinds were dominant to them. Movements away by subordinates were more likely to involve a break from feeding. Feeding rate, as measured by bite rate, increased with distance from dominant neighbours, but was unaffected by the distance to subordinates. It appears that aggressive interactions had little direct effect on access to food. Instead, it is suggested that feeding competition in red deer hinds is largely a passive process, operating through the avoidance of conflict by subordinates.

  Title A Review of Learning Behavior in Horses and its Application in Horse Training Type Journal Article
  Year 1990 Publication Journal of Animal Science Abbreviated Journal J. Anim Sci.  
  Volume 68 Issue 1 Pages (down) 75-81  
  Keywords  
  Abstract A literature review of the equine learning research conducted in the past 20 yr revealed that the purpose of most of the studies was to determine whether horses respond to learning situations in the same way that other animals do. The results indicated that horses can discriminate many different types of stimuli, and they learn through stimulus-response- reinforcement chains. Most equine learning studies have utilized learning tasks depending on primary positive reinforcement to get the horses to work the tests. Yet, the majority of horse trainers use negative reinforcement more often than primary positive reinforcement in their training procedures. Therefore, past research often did not have a direct application to training methods commonly utilized in the horse industry. Research also demonstrated that 1) early experiences of horses can affect learning ability later, 2) equine memory is efficient and 3) concentrating learning mals in long training sessions decreases equine learning efficiency. Many factors that might affect equine learning ability and be applicable to training practices in the horse industry have not been thoroughly investigated; for example, interactions between nutrition and learning and between exercise and learning, the use of negative and secondary reinforcements in horse training, and the horse's ability to make few initial errors compared to its ability to eliminate errors as training progresses all require investigation in future equine learning studies.

  Title A demonstration of observational learning in rats using a bidirectional control Type Journal Article
  Year 1990 Publication Quarterly Journal of Experimental Psychology Section B: Comparative and Physiological Psychology Abbreviated Journal Q J Exp Psychol B

  Abstract Hungry rats observed a conspecific demonstrator pushing a single manipulandum, a joystick, to the right or to the left for food reward and were then allowed access to the joystick from a different orientation. The effects of right-pushing vs left-pushing observation experience on (1) response acquisition, (2) reversal of a left-right discrimination, and (3) responding in extinction, were examined. Rats that had observed left-pushing made more left responses during acquisition than rats that had observed right-pushing, and rats that had observed demonstrators pushing in the direction that had previously been reinforced took longer to reach criterion reversal and made more responses in extinction than rats that had observed demonstrators pushing in the opposite direction to that previously reinforced. These results provide evidence that rats are capable of learning a response, or a response-reinforcer contingency, through conspecific observation.

  Title Interventions in a herd of semi – captive Plains zebras Type Journal Article
  Year 1990 Publication Behavior Abbreviated Journal Behaviour  
  Volume 112 Issue 1-2 Pages (down) 53-83  
  Keywords  
  Abstract n a herd of semi-captive plains zebras interventions, which occurred within the harems, were investigated in order to answer the question why zebras interfered. These interventions are of interest because they regulate the contacts between companions and because, as corrective and preventive measures, they reveal the normative principles underlying the behaviours by which animals structure their social environment. An attempt was made to deduce 1) the internal norms of the interferer; 2) his short term aims; 3) his tactis and 4) his perception of the social environment. The analysis revealed that in the case of an affiliative interaction foals, yearlings and adult mares started to interfere if a friend had an affiliative contact with another zebra. In view of the interferer's behaviours it was concluded that their aim was to break off the ongoing interaction and that zebras tended to protect friendship bonds. Foals and yearlings further interfered if their mother was being threatened, attacked or sexually approached by a stallion. In view of the interferer's behaviours its aim was to prevent iminent interactions or to break off ongoing interactions. This suggests that these interventions were of a protective nature. The interferer's behaviours in both contexts ware very much alike. Mares tended to interfere if their foal/yearling or adult daughter was threathened or aggressed or if a mare friend was being sexually approached by a stallion. This type of intervention was of a protective nature. Stallions in a multi male harem showed a high tendency to interfere in courtship interactions. From the resemblance between interventions in courtship and in aggressive interactions it is concluded that, at leat in a number of cases, the individuals have perceived courtship behaviour by the stallion as a threat towards the mare involved.

  Title Dominance, leadership, and aggression: animal behavior studies during the Second World War Type Journal Article
  Year 1990 Publication Journal of the History of the Behavioral Sciences Abbreviated Journal J Hist Behav Sci  
  Volume 26 Issue 1 Pages (down) 3-16  
  Keywords *Aggression; Animals; Behavior, Animal; *Dominance-Subordination; History, 20th Century; *Leadership; Political Systems; *Social Dominance; United States  
  Abstract During the decade surrounding the Second World War, an extensive literature on the biological and psychological basis of aggression surfaced in America, a literature that in general emphasized the significance of learning and environment in the origins of aggressive behavior. Focusing on the animal behavior research of Warder Clyde Allee and John Paul Scott, this paper examines the complex interplay among conceptual, institutional, and societal forces that created and shaped a discourse on the subjects of aggression, dominance, and leadership within the context of World War II. The distinctions made between sexual and social dominance during this period, distinctions accentuated by the threat of totalitarianism abroad, and the varying ways that interpretations of behavior could be negotiated attests to the multiplicity of interactions that influence the development of scientific research.
