	Title	The social nature of primate cognition			Type	Journal Article
	Year	2005	Publication	Proceedings. Biological Sciences / The Royal Society	Abbreviated Journal	Proc Biol Sci
	Volume	272	Issue	1575	Pages	1865-1875
	Keywords	Animals; Brain/anatomy & histology/physiology; Cognition/physiology; Evolution; Intelligence/physiology; Primates/physiology; Social Behavior
	Abstract	The hypothesis that the enlarged brain size of the primates was selected for by social, rather than purely ecological, factors has been strongly influential in studies of primate cognition and behaviour over the past two decades. However, the Machiavellian intelligence hypothesis, also known as the social brain hypothesis, tends to emphasize certain traits and behaviours, like exploitation and deception, at the expense of others, such as tolerance and behavioural coordination, and therefore presents only one view of how social life may shape cognition. This review outlines work from other relevant disciplines, including evolutionary economics, cognitive science and neurophysiology, to illustrate how these can be used to build a more general theoretical framework, incorporating notions of embodied and distributed cognition, in which to situate questions concerning the evolution of primate social cognition.

	Title	Both social and ecological factors predict ungulate brain size			Type	Journal Article
	Year	2006	Publication	Proceedings. Biological Sciences / The Royal Society	Abbreviated Journal	Proc Biol Sci
	Volume	273	Issue	1583	Pages	207-215
	Keywords	Animals; Artiodactyla/anatomy & histology/physiology; Brain/anatomy & histology/physiology; Ecosystem; Organ Size; Perissodactyla/anatomy & histology/physiology; *Social Behavior
	Abstract	Among mammals, the members of some Orders have relatively large brains. Alternative explanations for this have emphasized either social or ecological selection pressures favouring greater information-processing capacities, including large group size, greater foraging efficiency, higher innovation rates, better invasion success and complex problem solving. However, the focal taxa for these analyses (primates, carnivores and birds) often show both varied ecological competence and social complexity. Here, we focus on the specific relationship between social complexity and brain size in ungulates, a group with relatively simple patterns of resource use, but extremely varied social behaviours. The statistical approach we used, phylogenetic generalized least squares, showed that relative brain size was independently associated with sociality and social complexity as well as with habitat use, while relative neocortex size is associated with social but not ecological factors. A simple index of sociality was a better predictor of both total brain and neocortex size than group size, which may indicate that the cognitive demands of sociality depend on the nature of social relationships as well as the total number of individuals in a group.

	Title	Primate cognition: from 'what now?' to 'what if?'			Type	Journal Article
	Year	2003	Publication	Trends in Cognitive Sciences	Abbreviated Journal	Trends. Cognit. Sci.
	Volume	7	Issue	11	Pages	494-497
	Keywords
	Abstract	The 'social brain' hypothesis has had a major impact on the study of comparative cognition. However, despite a strong sense, gained from both experimental and observational work, that monkeys and apes differ from each other, we are still no closer to understanding exactly how they differ. We hypothesize that the dispersed social systems characteristic of ape societies explains why monkeys and apes should differ cognitively. The increased cognitive control and analogical reasoning ability needed to cope with life in dispersed societies also suggests a possible route for human cognitive evolution. This hypothesis is supported by behavioural and neurobiological data, but we need more of both if we are to fully understand how our primate cousins see the world.

	Title	Reconciliation patterns among stumptailed macaques: a multivariate approach			Type	Journal Article
	Year	1999	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	58	Issue	1	Pages	165-172
	Keywords
	Abstract	This study focused on two aspects of the dynamics of reconciliation in stumptailed macaques, Macaca arctoides. First, we investigated the combined effects of multiple variables (i.e. sex, age, rank, conflict intensity, outcome, or number of participants, interopponent distance, kinship and friendship) on the occurrence of reconciliation. Second, we investigated whether opponents used different behaviour patterns in their postconflict reunions depending on the characteristics of their conflicts or their relationship with their opponents. We studied a multimale, multifemale group of 38 stumptailed macaques housed in a large outdoor compound. Three types of data were collected: (1) instantaneous scan sampling of contact sitting to infer 'friendship'; (2) ad libitum data on bared-teeth and teeth-chattering displays to infer dominance rank; (3) 10-min focal observations during postconflict (PC) and matched control (MC) periods in which we recorded interopponent distance at the beginning of the observation and all aggressive and affiliative behaviours between former opponents. Our study confirmed the high conciliatory tendency of stumptailed macaques previously reported for other groups. A stepwise logistic regression revealed that initial interopponent distance in PC, friendship and kinship were the only factors that independently contributed to explain the occurrence of reconciliation. Two main clusters of postconflict behavioural patterns emerged: allogrooming+contact sitting and sociosexual behaviours (e.g. hold-bottom). It is hypothesized that postconflict allogrooming and contact sitting may be used for the maintenance of valuable relationships, whereas sociosexual behaviours may be used more indiscriminately by any pair of opponents as a buffering mechanism to prevent immediate recurrence of aggression.

	Title	Teaching in tandem-running ants			Type	Journal Article
	Year	2006	Publication	Nature	Abbreviated Journal	Nature
	Volume	439	Issue	7073	Pages	153
	Keywords	Animal Communication; Animals; Ants/physiology; Feedback/physiology; Learning/physiology; Teaching
	Abstract	The ant Temnothorax albipennis uses a technique known as tandem running to lead another ant from the nest to food--with signals between the two ants controlling both the speed and course of the run. Here we analyse the results of this communication and show that tandem running is an example of teaching, to our knowledge the first in a non-human animal, that involves bidirectional feedback between teacher and pupil. This behaviour indicates that it could be the value of information, rather than the constraint of brain size, that has influenced the evolution of teaching.

	Title	The value of the Piagetian framework for comparative cognitive studies			Type	Journal Article

	Volume	5	Issue	3	Pages	177-182
	Keywords	Animals; Behavior, Animal; Cognition; Discrimination Learning; Intelligence; Models, Psychological; *Models, Theoretical
	Abstract	Although the Piagetian framework has been used by numerous researchers to compare cognitive abilities of diverse species, the system is often criticized as implemented. I examine the various criticisms, suggest ways in which the system can be improved, and argue for the need for descriptive systems such as the Piagetian framework to complement programs that look for cellular and molecular bases or mathematical models to explain behavior.

	Title	Cone excitation ratios correlate with color discrimination performance in the horse (Equus caballus)			Type	Journal Article
	Year	2006	Publication	Journal of comparative psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	120	Issue	4	Pages	438-448
	Keywords	Animals; Behavior, Animal; Color Perception; Discrimination (Psychology); Discrimination Learning; Horses; Photoreceptors, Vertebrate/*physiology
	Abstract	Six horses (Equus caballus) were trained to discriminate color from grays in a counterbalanced sequence in which lightness cues were irrelevant. Subsequently, the pretrained colors were presented in a different sequence. Two sets of novel colors paired with novel grays were also tested. Performance was just as good in these transfer tests. Once the horse had learned to select the chromatic from the achromatic stimulus, regardless of the specific color, they were immediately able to apply this rule to novel stimuli. In terms of the underlying visual mechanisms, the present study showed for the first time that the spectral sensitivity of horse cone photopigments, measured as cone excitation ratios, was correlated with color discrimination performance, measured as accuracy, repeated errors, and latency of approach.

	Title	The effect of increasing visual horizons on stereotypic weaving: implications for the social housing of stabled horses			Type	Journal Article
	Year	2000	Publication		Abbreviated Journal	Appl Anim Behav Sci
	Volume	69	Issue	1	Pages	67-83
	Keywords
	Abstract	Stabled horses commonly perform stereotypic patterns of weaving, where the horse shifts its weight from side to side often swinging its head. Ten warm-blood types, of which five were known to reliably weave, were housed in similar 12x12 ft wooden loose boxes in a single stable block surrounding a courtyard. Each horse was exposed to each of five stable designs. These were: the conventional front top-half of the door open only with a view of the stable courtyard (F); front half-door open and a similar half-door open at the back of the stable with a view to the surrounding fields (FB); back open only (B); front and one-side panel open with a view into the adjacent stable (FS); and front, back and both sides open (All4). During observation days, horses were brought in from the field at 0830 h, fed concentrate at 0930 h, fed haylage at 1005 h and turned out at 1600 h. Behaviour was recorded from 0900 to 1040 h, 1200 to 1300 h and 1500 to 1600 h. Weaving was most common prior to feeding in the morning and prior to putting out to pasture in the afternoon. There was a significant effect of stable design on weaving, with less weaving in the FS and All4 designs than the F treatment. There was also a significant effect of stable design on repetitive nodding, though in this case, FB, B, FS and All4 designs each reduced nodding compared with the F treatment. The effect of stable design can be explained in a number of ways. Firstly, it could be the novelty of the environmental change, though there was no evidence in this study of an increase in stereotypy with prolonged exposure to the new stable designs. Secondly, opening windows may increase opportunities for environmental interaction, and the expression of new activities may compete with stereotypic behaviour for the horse's time. Thirdly, the open windows may allow expression of specific activities such as environmental monitoring or social interaction that are denied by the conventional stable.

	Title	Grooming and coalitions in Japanese macaques (<em>Macaca fuscata</em>): Partner choice and the time frame reciprocation			Type	Journal Article
	Year	2007	Publication	Journal of Comparative Psychology	Abbreviated Journal
	Volume	121	Issue	2	Pages	181-188
	Keywords	Altruism; Animal Grooming Behavior; Animal Social Behavior; Reciprocity; Monkeys
	Abstract	Evidence of a reciprocal exchange of grooming and agonistic support in primates is mixed. In this study, the authors analyzed a large database of grooming and coalitions in captive female Japanese macaques (Macaca fuscata) to investigate their within-group distribution and temporal relations. Macaques groomed preferentially those individuals that groomed them most and supported preferentially those individuals that supported them most. They also supported preferentially those individuals that groomed them most and groomed preferentially those individuals that supported them most. These results were not explained by covariation of grooming and support with third variables such as kinship, rank, or time spent in proximity. However, receiving grooming did not increase the short-term probability of supporting a partner, and being supported did not increase the short-term probability of grooming a partner. The proximate mechanisms underlying the exchange of services were discussed in relation to the time frame of the behavioral choices made by the monkeys.
