Title Animals Remember Previous Facial Expressions that Specific Humans Have Exhibited Type Journal Article
Year 2018 Publication Current Biology Abbreviated Journal
Volume 28 Issue 9 Pages 1428-1432.e4
Keywords (up) affective processing; face processing; ; animal-human interaction; interspecific communication; animal memory
Abstract Summary For humans, facial expressions are important social signals, and how we perceive specific individuals may be influenced by subtle emotional cues that they have given us in past encounters. A wide range of animal species are also capable of discriminating the emotions of others through facial expressions [1, 2, 3, 4, 5], and it is clear that remembering emotional experiences with specific individuals could have clear benefits for social bonding and aggression avoidance when these individuals are encountered again. Although there is evidence that non-human animals are capable of remembering the identity of individuals who have directly harmed them [6, 7], it is not known whether animals can form lasting memories of specific individuals simply by observing subtle emotional expressions that they exhibit on their faces. Here we conducted controlled experiments in which domestic horses were presented with a photograph of an angry or happy human face and several hours later saw the person who had given the expression in a neutral state. Short-term exposure to the facial expression was enough to generate clear differences in subsequent responses to that individual (but not to a different mismatched person), consistent with the past angry expression having been perceived negatively and the happy expression positively. Both humans were blind to the photograph that the horses had seen. Our results provide clear evidence that some non-human animals can effectively eavesdrop on the emotional state cues that humans reveal on a moment-to-moment basis, using their memory of these to guide future interactions with particular individuals.

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 (up) 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 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 The effect of development and individual differences in pointing comprehension of dogs Type Journal Article
Year 2009 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 12 Issue 3 Pages 471-479
Keywords (up) Age Factors; Analysis of Variance; Animals; *Association Learning; Attention; Chi-Square Distribution; Choice Behavior; *Comprehension; *Concept Formation; Dogs/*psychology; Female; *Gestures; Humans; Male; Orientation; Statistics, Nonparametric
Abstract In spite of the rather different procedures actually used in comparative studies to test the ability of different species to rely on the human pointing gesture, there is no debate on the high performance of dogs in such tasks. Very little is known, however, on the course through which they acquire this ability or the probable factors influencing the process. Important developmental questions have remained unsolved and also some methodological concerns should be addressed before we can convincingly argue for one interpretation or another. In this study we tested 180 dogs of different age (from 2 months to adults) to investigate their performance in the human distal momentary pointing gesture. The results, analyzed at both the group and the individual levels, showed no difference in the performance according to age, indicating that in dogs the comprehension of the human pointing may require only very limited and rapid early learning to fully develop. Interestingly, neither the keeping conditions nor the time spent in active interaction with the owner, and not even some special (agility) training for using human visual cues, had significant effect on the success and explained individual differences. The performance of the dogs was rather stable over time: during the 20 trials within a session and even when subsamples of different age were repeatedly tested. Considering that in spite of the general success at the group level, more than half of the dogs were not successful at the individual level, we revealed alternative “decision-making rules” other than following the pointing gesture of the experimenter.

Title Effects of imprint training procedure at birth on the reactions of foals at age six months Type Journal Article
Year 2003 Publication Equine Veterinary Journal Abbreviated Journal Equine Vet J
Volume 35 Issue 2 Pages 127-132
Keywords (up) Age Factors; Animal Husbandry/methods; Animals; Animals, Newborn/*psychology; *Behavior, Animal; *Bonding, Human-Pet; Female; Handling (Psychology); Horses/*psychology; Humans; *Imprinting (Psychology); Male; Random Allocation; Socialization; Time Factors
Abstract REASONS FOR PERFORMING STUDY: While imprint training procedures have been promoted in popular magazines, they have received limited scientific investigation. OBJECTIVES: To determine the effects of a neonatal imprint training procedure on 6-month-old foals and to determine if any one session had a greater effect than others. METHODS: Foals (n = 131) were divided into the following treatments: no imprint training, imprint training at birth, 12, 24 and 48 h after birth or imprint training only at birth, 12, 24, 48, or 72 h after birth. Foals then received minimal human handling until they were tested at 6 months. RESULTS: During training, time to complete exposure to the stimulus was significant for only 2 of 6 stimuli. Percentage change in baseline heart rate was significant for only 2 of 10 stimuli. These 4 effects were randomly spread across treatments. CONCLUSIONS: Neither the number of imprint training sessions (0, 1, or 4) nor the timing of imprint training sessions (none, birth, 12, 24, 48, or 72 h after birth) influenced the foal's behaviour at 6 months of age. POTENTIAL CLINICAL RELEVANCE: In this study, imprint training did not result in better behaved, less reactive foals.

Title Behavioral measurement of temperament in male nursery-raised infant macaques and baboons Type Journal Article
Year 1999 Publication American journal of primatology Abbreviated Journal Am. J. Primatol.
Volume 47 Issue 1 Pages 43-50
Keywords (up) Age Factors; Animal Technicians; Animals; Animals, Newborn/psychology; Behavior, Animal/*physiology; Defecation; Facial Expression; Humans; Irritable Mood; Macaca fascicularis/*psychology; Male; Papio/*psychology; Sex Characteristics; Species Specificity; Temperament/*physiology; Urination; Vocalization, Animal; Weaning
Abstract We define temperament as an individual's set of characteristic behavioral responses to novel or challenging stimuli. This study adapted a temperament scale used with rhesus macaques by Schneider and colleagues [American Journal of Primatology 25:137-155, 1991] for use with male pigtailed macaque (Macaca nemestrina, n = 7), longtailed macaque (M. fascicularis, n = 3), and baboon infants (Papio cynocephalus anubis, n = 4). Subjects were evaluated twice weekly for the first 5 months of age during routine removal from their cages for weighing. Behavioral measures were based on the subject's interactions with a familiar human caretaker and included predominant state before capture, response to capture, contact latency, resistance to tester's hold, degree of clinging, attention to environment, defecation/urination, consolability, facial expression, vocalizations, and irritability. Species differences indicated that baboons were more active than macaques in establishing or terminating contact with the tester. Temperament scores decreased over time for the variables Response to Capture and Contact Latency, indicating that as they grew older, subjects became less reactive and more bold in their interactions with the tester. Temperament scores changed slowly with age, with greater change occurring at younger ages. The retention of variability in reactivity between and within species may be advantageous for primates, reflecting the flexibility necessary to survive in a changing environment.
