  Title Primates, brains and ecology Type Journal Article
  Year 1980 Publication Journal of Zoology Abbreviated Journal J. Zool. Lond.  
  Volume 190 Issue 3 Pages 309-323  
  Keywords  
  Abstract The paper examines systematic relationships among primates between brain size (relative to body size) and differences in ecology and social system. Marked differences in relative brain size exist between families. These are correlated with inter-family differences in body size and home range size. Variation in comparative brain size within families is related to diet (folivores have comparatively smaller brains than frugivores), home range size and possibly also to breeding system. The adaptive significance of these relationships is discussed.

  Title Performance correlates of social behavior and organization: Social rank and reversal learning in crab-eating macaques (M. fascicularis) Type Journal Article
  Year 1980 Publication Primates Abbreviated Journal Primates  
  Volume 21 Issue 3 Pages 376-388  
  Keywords  
  Abstract Abstract  Seventeen male crab-eating macaques drawn from two captive troops, were tested on a brightness discrimination, reversal learning task. Fourteen of these animals completed ten reversals. It was found that the performance of the three highest ranking animals from each troop, taken together, was poorer than that of the lower ranking animals that were tested. The high ranking animals made more errors before reaching criterion on both initial learning and the reversal problems. Analysis of error patterns revealed that, while the high ranking animals had no more difficulty than the others in withholding their responses to the previously correct stimulus following reversals, they did not adopt the correct strategy as soon as the low ranking animals. The results have been interpreted in terms of a carry-over of a hypothetical factor or factors resulting from pressures created by the ongoing social dynamics involved in establishing and maintaining a given social rank at the time laboratory testing occurred.

  Title Performance correlates of social behavior and organization: Social rank and complex problem solving in crab-eating macaques (M. fascicularis) Type Journal Article
  Year 1980 Publication Primates Abbreviated Journal Primates  
  Volume 21 Issue 4 Pages 515-523  
  Keywords  
  Abstract Abstract  Seventeen male crab-eating macaques, drawn from two captive troops, were tested on a series of complex problem solving tasks in a Wisconsin General Test Apparatus (wgta). The animals were trained on a series of 6-trial object quality learning set problems followed by a series of 10-trial object quality learning set problems. They were then given problems in which the correct stimulus object was reversed part way through the problem. After the animals reached criterion on this task, the reversal learning set was then extinguished. High ranking animals made more intraproblem errors than low ranking animals on the 6-trial problems, but there was no relationship between social status and the rapidity with which the object quality learning set was established. Animals that received overtraining on the 6-trial problems transferred their learning virtually intact to the 10-trial problems; however, high ranking animals without overtraining made more errors than low ranking animals. On reversal learning and reversal extinction, high ranking animals made more errors on critical trials, indicating that they formed and extinguished the reversal set more slowly than low ranking animals. Object quality sets, as measured by trial-2 performance, were not affected by the reversal conditions.

  Title Stability of equine hierarchies and the prevention of dominance related aggression Type Journal Article
  Year 1980 Publication Equine veterinary journal Abbreviated Journal Equine Vet J  
  Volume 12 Issue 1 Pages 15-18  
  Keywords *Aggression; Animals; *Behavior, Animal; Feeding Behavior; Female; *Hierarchy, Social; *Horses; Humans; Male; Maternal Behavior; *Social Dominance  
  Abstract The dominance hierarchy of a herd of 10 Thoroughbred mares was determined twice, at an interval of 18 months, using paired feeding tests. Each mare's rank was correlated significantly between the 2 tests. This indicated that the hierarchy within the herd was stable. The offspring of dominant and subordinate mares were also tested for dominance in their own age groups. The offspring of dominant mares tended to be near the top of the hierarchy while those of middle and low ranking mares were not consistently found in the middle or bottom of their own hierarchies. Paired feeding tests were carried out on 8 ponies. During tests the time that each pony spent eating and the ponies' aggressive interactions were recorded. Two situations were used. Each pony-pair was tested when both ponies were in the same paddock and also when they were separated by a rail fence. The subordinate ponies spent significantly more time eating and the domonant pony was significantly less aggressive, when the pony-pair was separated by a fence than when they were in one paddock. It was concluded that the dominance hierarchies of adult horse groups changed very little over time and that the foals of dominant mares will tend to be dominant in their own age groups. Management practices can be used to reduce aggression and consequent injury that may arise in group feeding situations.

  Title Types of dominance in a chimpanzee colony Type Journal Article
  Year 1980 Publication Folia primatologica; international journal of primatology Abbreviated Journal Folia Primatol (Basel)  
  Volume 34 Issue 1-2 Pages 90-110  
  Keywords Agonistic Behavior; Animals; Animals, Zoo; *Behavior, Animal; Competitive Behavior; Factor Analysis, Statistical; Female; Hierarchy, Social; Male; *Pan troglodytes; *Social Dominance  
  Abstract This study examines to what extent the concept of dominance can be used to describe the social structure of a group of semi-free-living chimpanzees. 15 behavioural variables, based on agonistic, competitive and affinitive behaviour patterns, have been compared with respect to the interindividual directions in which they occurred. In this analysis use was made of indices that reflect the position an individual occupies in the relationship structure. These indices were calculated per individual for all variables and subjected to factor analysis and cluster analysis. As a result, 13 of the variables could be grouped in three categories which have been labelled: (1) agonistic dominance; (2) bluff dominance, and (3) competitive dominance. Whereas the top positions in the hierarchies based on the first two closely related types of dominance were occupied by the adult males, the hierarchy based on the third type was headed by several adult females.
