  Title Intelligent perception Type Journal Article
  Year 1998 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 57 Issue 3-4 Pages 213-231  
  Keywords Intelligent perception; Environmental changes; Primates  
  Abstract For an animal from any species to exhibit intelligent perception it must be capable of being consciously aware of what it perceives and capable of learning from this experience. Although many organisms, and for that matter machines, are capable of rapid adaptive learning in response to perception of environmental changes, such adaptations can occur without them being consciously aware either of external stimuli or their response to them. While behavioural and neurophysiological evidence suggests that, apart from ourselves, other higher primates must also be capable of such awareness, an important central question is whether such awareness is a characteristic of primate evolution or if it also occurs in sub-primate mammals as well. In this review I will examine our behavioural and neurophysiological evidence from visual and olfactory recognition studies in the sheep to support the argument that they are likely to be aware of and learn about both social and non-social objects and that they are therefore capable of intelligent perception. However, the impact of motivational changes on these perceptual processes suggests that they may be limited in terms of both prospection and retrospection and dealing with symbolic associations.

  Title “Intervenors” in agonistic interactions amongst domesticated goats Type Journal Article
  Year 1998 Publication Zeitschrift fur Säugetierkunde Abbreviated Journal Z. Säugetierk.  
  Volume 63 Issue 5 Pages 266-272  
  Keywords Behaviour; Domestication; Goat; Intervention; Rank order  
  Abstract Social behaviour was observed in individually marked goats in two herds. The goats from one herd (n = 98) were horned, those of the other herd (n = 83) were polled. By recording agonistic interactions within the herds, a dominance index was determined for each animal. In both herds, intervention took place. Intervention is defined as one animal pushing in between two fighters, and thus ending the fight. More cases of intervention took place per individual animal amongst the horned goats than amongst the polled ones. Goats which intervened in fights on several occasions usually had a high dominance index. Members of the herd which were observed intervening only once had an average dominance index in both herds of almost 0.5. In some cases, goats very low in the rank order intervened a fight. Only rarely did the intervenors have a lower dominance index than the two fighters. In 103 cases, the direct dominance relationship between a fighting animal and the intervenor was known. In 95 cases (92.2%), the intervenor was dominant to the herd member in this fight and in just eight cases (7.8%), it was subordinate. It could not be determined what advantage the intervenor gained from its activity. It is possible that, at least in certain cases, a particularly relationship existed between the intervenor and one of the fighters.

  Title Individual recognition and memory in lobster dominance Type Journal Article
  Year 1998 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 56 Issue 6 Pages 1553-1560  
  Keywords  
  Abstract American lobsters,Homarus americanus, form stable dominance relationships in captivity. Size, sex and stage in the moult cycle are important determinants for dominance. Other factors, such as recent agonistic experience play a role. This paper investigates how lobsters maintain their stable dominance relationships: they may recognize individuals or alternatively, recognize overall dominance status. We paired lobsters in two consecutive `boxing matches'. Results indicate that lobsters remember familiar opponents when kept either in isolation or in communal tanks for 24 h between their first and second fights. Subordinates immediately backed away from familiar dominants, avoiding a second fight. In some animals, this memory lasted between 1-2 weeks if pairs were kept separate between the first and second fights. When paired for the second fight against unfamiliar dominant lobsters, subordinate lobsters from first fights actively fought and won the encounter. These results suggest that lobsters are capable of `individual recognition'. In nature, the observed social organization of lobsters may be maintained by individual recognition of a small number of residents inhabiting separate, nearby shelters.

  Title On the Proper Definition of Cognitive Ethology Type Book Chapter
  Year 1998 Publication Animal Cognition in Nature Abbreviated Journal  
  Volume Issue Pages 1-28  
  Keywords  
  Abstract Summary The last 20-30 years have seen two `scientific revolutions' in the study of animal behavior: the cognitive revolution that originated in psychology, and the Darwinian, behavioral ecology revolution that originated in biology. Among psychologists, the cognitive revolution has had enormous impact. Similarly, among biologists, the Darwinian revolution has had enormous impact. The major theme of this chapter is that these two scientific research programs need to be combined into a single approach, simultaneously cognitive and Darwinian, and that this single approach is most appropriately called cognitive ethology.

  Title Pair-bonding, female aggression and the evolution of lemur societies Type Journal Article
  Year 1998 Publication Folia Primatologica; International Journal of Primatology Abbreviated Journal Folia Primatol (Basel)  
  Volume 69 Suppl 1 Issue Pages 1-13  
  Keywords *Aggression; Animals; Evolution; Female; Intelligence; Lemur/*psychology; Male; *Pair Bond; Sex Factors; Social Dominance; Strepsirhini/psychology  
  Abstract Lemur societies have been described as convergent with those of anthropoids, including Papio-like female-bonded multi-male groups. Recent research, however, shows at least 5 pair-bonded species among the Lemuridae and Indriidae. Three more, Eulemur mongoz, Eulemur fulvus and Varecia variegata, have societies combining aspects of pairing with aspects of troop life. The best-known female-bonded societies, those of Lemur catta, Propithecus diadema edwardsi and Propithecus verreauxi, may be assemblages of mother-daughter dyads, capable of high aggression towards other females, but derived from more solitary female ancestors, perhaps also living as pairs. The internal structure of such lemur groups differs from the more extensive kin groups of catarrhines. This in turn may relate to the lemurs' level of social intelligence and to lemur female dominance over males.

  Title Watch and learn: preview of the fighting ability of opponents alters contest behaviour in rainbow trout Type Journal Article
  Year 1998 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 56 Issue 3 Pages 771-776  
  Keywords  
  Abstract The costs associated with initial conflicts could be reduced if animals can assess the fighting ability of possible future opponents by watching their contest success against other individuals. We tested this hypothesis by conducting repeated dyadic dominance trials on size-matched juvenile rainbow trout,Oncorhynchus mykiss. In the first trial a dyadic contest was `observed' by a single fish separated by a transparent divider. In the second trial, the observer was paired against either the `familiar' dominant fish or an unfamiliar dominant fish from the first trial. We predicted that observers should settle conflicts with previewed opponents faster and with less aggression than those with unfamiliar fish. This prediction was supported for observers that lost against a previewed competitor, since these fish reduced their aggression more rapidly than did unfamiliar observers. Familiar observers that won, however, showed a more rapid increase in aggression compared with unfamiliar winning observers. This suggests that, regardless of whether an observer challenges the initial dominant, this `decision' is taken more rapidly in conflicts with preassessed contestants, because of the a priori information about their fighting ability. Since preassessment could save energy and allow effort to be concentrated on contests with a high payoff/probability of winning, selection may favour preview strategies when contest competition over resources is important for fitness.

  Title Lateralized behavior and lymphocyte counts in chimpanzees (pan troglodytes): A cross-sectional and longitudinal assessment Type Journal Article
  Year 1998 Publication Developmental Neuropsychology Abbreviated Journal Developmental Neuropsychology  
  Volume 14 Issue 4 Pages 519-533  
  Keywords  
  Abstract Cross?sectional and longitudinal assessment of lymphocyte count and behavioral laterality was examined in a sample of captive chimpanzees (Pan troglodytes) to assess the validity of the Geschwind?Behan?Galaburda (GBG) theory of cerebral lateralization. For the cross?sectional analysis, chimpanzees classified as right?handed for feeding exhibited lower lymphocyte counts than chimpanzees classified as either ambiguously handed or left?handed. Longitudinal analysis indicated that some measures of laterality within the first 3 months of life predicted (a) direction of hand preference at 2 to 5 years of age and (b) lymphocyte counts for the first 3 years of life. The association between lymphocyte count and behavioral laterality was more evident in males than females. Taken together, the results support some aspects of the GBG theory.
