  Title Cognitive function in mammals: the evolutionary perspective Type Journal Article
  Year 1996 Publication Brain research. Cognitive brain research Abbreviated Journal Brain Res Cogn Brain Res  
  Volume 3 Issue 3-4 Pages 279-290  
  Keywords Animals; Cognition/*physiology; Conditioning (Psychology)/*physiology; Evolution; Humans; Learning/*physiology; Task Performance and Analysis  
  Abstract The work of behavioural pharmacologists has concentrated on small animals, such as rodents and pigeons. The validity of extrapolation of their findings to humans depends upon the existence of parallels in both physiology and psychology between these animals and humans. This paper considers the question whether there are in fact substantial cognitive parallels between, first, different non-human groups of vertebrates and, second, non-humans and humans. Behavioural data from 'simple' tasks, such as habituation and conditioning, do not point to species differences among vertebrates. Using examples that concentrate on the performance of rodents and birds, it is argued that, similarly, data from more complex tasks (learning-set formation, transitive inference, and spatial memory serve as examples) reveal few if any cognitive differences amongst non-human vertebrates. This conclusion supports the notion that association formation may be the critical problem-solving process available to non-human animals; associative mechanisms are assumed to have evolved to detect causal links between events, and would therefore be relevant in all ecological niches. In agreement with this view, recent advances in comparative neurology show striking parallels in functional organisation of mammalian and avian telencephalon. Finally, it is argued that although the peculiarly human capacity for language marks a large cognitive contrast between humans and non-humans, there is good evidence-in particular, from work on implicit learning--that the learning mechanisms available to non--humans are present and do play an important role in human cognition.

  Title The influence of handling during different ages on a halter training test in foals Type Journal Article
  Year 1996 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 5 Issue 2 Pages 115-120  
  Keywords  
  Abstract Ten foals were used to determine effects of handling during different ages on their ability to perform a halter training test. Early-handled (EH) foals (n = 5) were handled in 10 min sessions 5 d weekly from 24 h after birth until 42 d of age, then were not handled from 43 to 84 d of age. Later-handled (LH) foals (n = 5) were not handled from birth to 42 d of age, then were handled in 10-min sessions 5 d weekly from 43 to 84 d of age. At 85 d of age, each foal was subjected to a 10 min halter training test for 5 consecutive d. The test consisted of an unfamiliar handler placing a halter on each foal and attempting to make the foal walk forward for 20 m. Data recorded during each d of the halter training were duration of initial struggle, number of lunges into the air, time to first forward step, time to five consecutive forward steps, and time to travel 20 m. At the end of the 5 d halter training test, the handler assigned a subjective test rating score to each foal based on ease of training. Split-plot analysis indicated that EH foals took less time (P < 0.05) to take one step forward, five consecutive steps forward, and to travel 20 m than LH foals. One-way ANOVA indicated that EH foals had a lower (more desirable) test ratings than LH foals (P < 0.01). Results indicate that handling throughout the first 42 d of life increased foal performance on this halter training task compared to handling from 43 to 84 d of age. These results may imply the existence of a critical handling period during the first 42 d of age or a phenomenon similar to learned helplessness

  Title The effects of pen size on the behaviour of farmed red deer stags confined in yards Type Journal Article
  Year 1996 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 47 Issue 3-4 Pages 247-253  
  Keywords Red deer; Handling; Density; Aggression; Farming  
  Abstract To determine whether pen size affected the behaviour and welfare of farmed red deer confined temporarily in yards, four groups of ten 2-year-old stags were confined for 40 min or 2 days in each of spring and summer, in either large (5 m × 4 m ) or small (2.5 m × 4) pens. In the small pens, wall pacing and vertical/horizontal head movements at the walls were more frequently observed (P < 0.05) and were carried out by a greater percentage of the deer (P < 0.001), and distances between individuals were smaller (P < 0.01), than observations in the large pens. Aggressive activities varied seasonally, with head-butting and chasing being seen most frequently in the spring (P < 0.05) and biting and kicking being seen most frequently in the summer (P < 0.05), and the overall frequency of aggressive activities was low in summer. In spring, in small pens there were fewer threats to head-butt, head butts by moving animals, and less stepping activity than in large pens (P < 0.05). In summer, in small pens there were more threats to butt and more stepping activity than in the large pens (P < 0.05). In both seasons, aggressive activities were correlated with wall pacing (r = 0.58 and 0.55, respectively). It was concluded that the effect of pen size on the frequency and nature of aggressive and other activities varied seasonally. In order minimise aggression and stepping activity, small pens were favoured in spring and large pens were favoured in summer. However, in both seasons there were greater inter-individual distances and reduced pacing and head movements at the walls in large pens. This latter finding may indicate that the large pens were less aversive to the deer, regardless of season.

  Title Ecology, feeding competition and social structure in baboons Type Journal Article
  Year 1996 Publication Behavioral Ecology and Sociobiology Abbreviated Journal Behav. Ecol. Sociobiol.  
  Volume 38 Issue 5 Pages 321-329  
  Keywords Key words Ecology – Competition – Group size – Baboons  
  Abstract Predictions of the model of van Schaik (1989) of female-bonding in primates are tested by systematically comparing the ecology, level of within-group contest competition for food (WGC), and patterns of social behaviour found in two contrasting baboon populations. Significant differences were found in food distribution (percentage of the diet from clumped sources), feeding supplant rates and grooming patterns. In accord with the model, the tendencies of females to affiliate and form coalitions with one another, and to be philopatric, were strongest where ecological conditions promoted WGC. Group fission in the population with strong WGC was “horizontal” with respect to female dominance rank, and associated with female-female aggression during a period of elevated feeding competition. In contrast, where WGC was low, females' grooming was focused on adult males rather than other females. Recent evidence suggests that group fission here is initiated by males, tends to result in the formation of one-male groups, and is not related to feeding competition but to male-male competition for mates. An ecological model of baboon social structure is presented which incorporates the effects of female-female competition, male-male competition, and predation pressure. The model potentially accounts for wide variability in group size, group structure and social relationships within the genus Papio. Socio-ecological convergence between common baboons and hamadryas baboons, however, may be limited in some respects by phylogenetic inertia.

  Title Development of intervention behavior in Japanese macaques: Testing the targeting hypothesis Type Journal Article
  Year 1996 Publication International Journal of Primatology Abbreviated Journal Int. J. Primatol.  
  Volume 17 Issue 3 Pages 429-443  
  Keywords Biomedical and Life Sciences  
  Abstract Matrilineal dominance systems, which characterize several species of cercopithecines, are determined largely by the patterning of third-party aggressive interventions in conflicts. Although the role of interventions in structuring rank relations has received much attention, very few studies have dealt specifically with the development of intervention behavior. In other words,most studies have focused on the interventions received and their effect on the recipients rather than on the interventions performed and the goals of the interveners. We analyzed the intervention behavior of 10 juvenile females in a colony of 40 Japanese macaques (Macaca fuscata)housed at the University of Montreal Laboratory of Behavioral Primatology. The analysis of 749 interventions performed by the juveniles over their first 4 years and 2425 interventions received over the same period reveals that (1) juvenile females intervened selectively against females ranking below their mother, (2) they began to intervene at about the same time that they began to challenge the latter females in dyadic contests, (3) they sided with females as well as with males against these females, (4) juvenile interveners incurred little risks in terms of aggressive retaliation from their targets, (5) they derived immediate benefits in terms of conflicts won over stronger targets, (6) interventions often did not take place when the possible recipients needed support, and (7) interveners did not conform to a pattern of mutually preferential support. These results support the view that interventions by juveniles are selfish (vs altruistic) and constitute a low-cost and effective means to target and to outrank prospectively subordinate females.

  Title Natural conceptual behavior in squirrel monkeys (saimiri sciureus): An experimental investigation Type Journal Article
  Year 1996 Publication Primates Abbreviated Journal Primates  
  Volume 37 Issue 3 Pages 327-332  
  Keywords  
  Abstract Abstract&nbsp;&nbsp;Natural conceptual discriminations have been tested in many different species, including pigeons and a variety of non-human primates. The ability of four male squirrel monkeys (Saimiri sciureus) to learn and use the natural concept “squirrel monkey” was investigated in this study. After a training phase, subjects were presented with novel stimuli in transfer and test trials. All subjects performed at a rate significantly above chance on the first test trial (p&lt;.001), indicating that squirrel monkeys can utilize natural concepts in the laboratory.
