Title Visual kin recognition and family resemblance in chimpanzees (Pan troglodytes) Type Journal Article
Year 2004 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 118 Issue 2 Pages 194-199
Keywords Animals; Female; Male; Pan troglodytes; Random Allocation; *Recognition (Psychology); *Visual Perception
Abstract (up) The male-offspring biased visual kin recognition in chimpanzees (Pan troglodytes) reported by L. A. Parr and F. B. M. de Waal (1999) was replicated with human (Homo sapiens) participants and a principal components analysis (PCA) of pixel maps of the chimpanzee face photos. With the same original materials and methods, both humans and the PCA produced the same asymmetry in kin recognition as found with the chimpanzees. The PCA suggested that the asymmetry was a function of differences in the distribution of global characteristics associated with the framing of the faces in the son and daughter test sets. Eliminating potential framing biases, either by cropping the photos tightly to the faces or by rebalancing the recognition foils, eliminated the asymmetry but not human participants' ability to recognize chimpanzee kin.

Title The organization of agonistic relations within two captive groups of Java-monkeys (Macaca fascicularis) Type Journal Article
Year 1977 Publication Zeitschrift für Tierpsychologie Abbreviated Journal Z. Tierpsychol.
Volume 44 Issue 3 Pages 225-282
Keywords Age Factors; Aggression; Animals; Behavior, Animal/*physiology; Competitive Behavior/*physiology; Fear; Female; Haplorhini; Humans; Macaca/*physiology; Macaca fascicularis/*physiology; Male; Sex Factors; Social Behavior; Social Dominance
Abstract (up) The paper offers a detailed quantitative descripition of the distribution of agonistic activities over the members of two groups of Java-monkeys (Macaca fascicularis). These groups lived in captivity and were well-established: i.e. they had an extensive network of genealogical relationships. The study pays special attention to agonistic interactions with three or more participants. Its main purpose is an analysis of the way dyadic agonistic relations (e.g. dominance relations) are affected by third group members and the relations among these. The paper presents data on the ontogeny of 'dependent dominance', the 'control role' of the alpha-male, and the functions of different types of alliances.

Title Behavioral retardation in a macaque with autosomal trisomy and aging mother Type Journal Article
Year 1996 Publication American journal of mental retardation : AJMR Abbreviated Journal Am J Ment Retard
Volume 100 Issue 4 Pages 378-390
Keywords Animals; *Behavior, Animal; Brain/physiopathology; Female; Hydrocephalus/complications; Longitudinal Studies; Macaca mulatta/*genetics; Magnetic Resonance Imaging; Male; *Maternal Age; Psychomotor Disorders/*etiology; Social Behavior; Trisomy/*genetics; X Chromosome
Abstract (up) The social development of a female rhesus monkey (Macaca mulatta) was followed from the day of birth until her death, at age 32 months. The subject, born to an older mother, had an extra autosome (karyotype: 43, XX, +18), an affliction that came about spontaneously. MRI scans revealed that she was also hydrocephalic. Compared to 23 female monkeys growing up under identical conditions, the subject showed serious motor deficiencies, a dramatic delay in the development of social behavior, poorly established dominance relationships, and greater than usual dependency on mother and kin. The subject was well-integrated into the social group, however.

Title Primates--A natural heritage of conflict resolution Type Journal Article
Year 2000 Publication Science (New York, N.Y.) Abbreviated Journal Science
Volume 289 Issue 5479 Pages 586-590
Keywords Aggression/*psychology; Animals; Behavior, Animal; *Conflict (Psychology); Female; Humans; Male; *Primates; *Social Behavior; Social Dominance
Abstract (up) The traditional notion of aggression as an antisocial instinct is being replaced by a framework that considers it a tool of competition and negotiation. When survival depends on mutual assistance, the expression of aggression is constrained by the need to maintain beneficial relationships. Moreover, evolution has produced ways of countering its disruptive consequences. For example, chimpanzees kiss and embrace after fights, and other nonhuman primates engage in similar “reconciliations.” Theoretical developments in this field carry implications for human aggression research. From families to high schools, aggressive conflict is subject to the same constraints known of cooperative animal societies. It is only when social relationships are valued that one can expect the full complement of natural checks and balances.

Title Empathy: Its ultimate and proximate bases Type Journal Article
Year 2002 Publication Behavioral and Brain Sciences Abbreviated Journal Behav Brain Sci
Volume 25 Issue 1 Pages 1-20; discussion 20-71
Keywords Adult; Animals; Child; Emotions/physiology; *Empathy; Evolution; Haplorhini; Helping Behavior; Humans; Mental Disorders/physiopathology/psychology; Morals; Personality Development; Phylogeny; Prefrontal Cortex/physiopathology; Socialization
Abstract (up) There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors (e.g., alarm, social facilitation, vicariousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators) that are crucial for the reproductive success of animals living in groups. The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature (similarity, familiarity, past experience, explicit teaching, and salience). It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations.

Title Inhibition of social behavior in chimpanzees under high-density conditions Type Journal Article
Year 1997 Publication American journal of primatology Abbreviated Journal Am. J. Primatol.
Volume 41 Issue 3 Pages 213-228
Keywords Aggression/*psychology; Animals; *Behavior, Animal; *Crowding; Female; Male; Pan troglodytes/*psychology; Population Density; *Social Environment; Stress, Psychological
Abstract (up) This is the first study to investigate the short-term effects of high population density on captive chimpanzees (Pan troglodytes). Subjects of the study were 45 chimpanzees living in five different groups at the Yerkes Regional Primate Research Center. The groups were observed under two conditions: 1) when they had access to both the indoor and outdoor sections of their enclosures; 2) during cold days when they were locked into the indoor runs, which reduced the available space by more than half. Under the high-density condition, allogrooming and submissive greetings decreased, but juvenile play increased. Remarkably, the rate of various forms of agonistic behavior, such as aggression, bluff charge, bluff display, and hooting, occurred less frequently under the high-density condition. This general decrease in adult social activity, including agonistic behavior, can be interpreted as an inhibition strategy to reduce opportunities for conflict when interindividual distances are reduced. This strategy is probably effective only in the short run, however. Behavioral indicators of anxiety, such as rough scratching and yawning, showed elevated rates, suggesting increased social tension under the high-density condition.

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 (up) 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.

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 (up) 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 The similarity principle underlying social bonding among female rhesus monkeys Type Journal Article
Year 1986 Publication Folia primatologica; international journal of primatology Abbreviated Journal Folia Primatol (Basel)
Volume 46 Issue 4 Pages 215-234
Keywords Aggression; Animals; Dominance-Subordination; Female; Grooming; *Group Processes; Macaca/*physiology; Macaca mulatta/*physiology; Male; *Object Attachment
Abstract (up) Twenty adult female rhesus monkeys (Macaca mulatta) were observed over a three-year period. They lived in a mixed captive group with kinship relations known for three generations. The study's aim was to test Seyfarth's [J. theor. Biol. 65: 671-698, 1977] model of rank-related grooming and to investigate two other possible determinants of social bonding, i.e. relative age and the group's stratification into two social classes. Data on affiliation, coalitions, and social competition were collected by means of both focal observation and instantaneous time sampling. Whereas certain elements of the existing model were confirmed, its explanatory principles were not. Social competition did not result in more contact among close-ranking females (the opposite effect was found), and the relation between affiliative behavior and coalitions was more complex than predicted. Based on multivariate analyses and a comparison of theoretical models, we propose a simpler, more encompassing principle underlying interfemale attraction. According to this 'similarity principle', rhesus females establish bonds with females whom they most resemble. The similarity may concern genetical and social background, age, hierarchical position and social class. Effects of these four factors were independently demonstrated. The most successful model assumed that similarity factors influence female bonding in a cumulative fashion.

Title Haptic discrimination in capuchin monkeys (Cebus apella): evidence of manual specialization Type Journal Article
Year 1997 Publication Neuropsychologia Abbreviated Journal Neuropsychologia
Volume 35 Issue 2 Pages 143-152
Keywords Aging/psychology; Animals; Cebus; Cues; Discrimination (Psychology)/*physiology; Female; Functional Laterality/*physiology; Male; Psychomotor Performance/physiology; Sex Characteristics; Touch/physiology
Abstract (up) Two experiments investigated the effects of haptic and visual discrimination on hand preference in 22 brown capuchin monkeys (Cebus apella). The percentage of left-handed subjects in Experiment 1 were 63.6%, 45.5%, and 18.2% for haptic, bipedal, and quadrupedal reaching, respectively. In Experiment 2, the haptic demands of the task were manipulated by using additional food types and another tactile medium. Left-hand preferences were further strengthened when reaching into water compared to pineshavings in Experiment 1. Reaching with no tactile interference resulted in equal numbers of lateralized and nonlateralized subjects. These results show that when reaching demands the use of haptic cues, as opposed to visual ones, monkeys shift towards greater left hand use. This is consistent with what is known about right hemisphere superiority for haptic discrimination in humans.
