	Title	Nestling recognition via direct cues by parental male bluegill sunfish ( Lepomis macrochirus)			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	2	Pages	87-92
	Keywords	Animals; Animals, Wild; Male; Ovum; Parasites; Perception; Perciformes; Pheromones; Recognition (Psychology); Sexual Behavior, Animal; *Smell; Social Behavior
	Abstract	Parental care can be costly to a parent in terms of both time and energy invested in the young. In species with cuckoldry or brood parasitism not all of the young under a parent's care are necessarily offspring. In such cases, distinguishing between kin and non-kin, and investing only in the former (nepotism), can be advantageous. Bluegill sunfish ( Lepomis macrochirus) are characterized by paternal care and cuckoldry, and care-providing males appear to show nepotistic behaviours. Here, we investigated nestling recognition in bluegill, determining whether parental males can differentiate between young from their own nest (familiar and related) and young from non-neighbouring nests (unfamiliar and unrelated) using (1) visual and chemical cues, and (2) chemical cues only. In the first experiment, wild-caught parental males were presented with samples of eggs or fry (newly hatched eggs) collected from their own nest or a foreign nest and placed on opposite sides of an aquarium. The time these parental males spent associating with each sample, and their “pecking” behaviours (indicating cannibalism), were recorded. Parental males showed no preference between eggs from their own nest and eggs from a non-neighbouring nest, but they preferred to associate with fry from their own nest over foreign fry. There also was a positive relationship between male body size and the time spent associated with fry from their own nest. Parental males pecked at foreign fry more than 5 times as often as fry from their own nest, though this difference was not statistically significant. In the second experiment, fry that were collected from the nest of a wild-caught parental male or a non-neighbouring nest were placed in different containers and the water from each was dripped into opposite ends of an aquarium. The time the male spent on each side was recorded. In this case, parental males spent more time near the source of water conditioned by unrelated fry, but there was a positive relationship between male condition (fat reserves) and the time he spent near the source of water conditioned by fry from his own nest. Results confirm that chemicals cue nestling recognition by parental male bluegill.

	Title	Perceptual biases for multimodal cues in chimpanzee (Pan troglodytes) affect recognition			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	3	Pages	171-178
	Keywords	Acoustic Stimulation; Animal Communication; Animals; Auditory Perception/physiology; Cues; Discrimination Learning/physiology; Facial Expression; Female; Male; Pan troglodytes/psychology; Perceptual Masking/physiology; Photic Stimulation; Recognition (Psychology)/physiology; Visual Perception/physiology; Vocalization, Animal
	Abstract	The ability of organisms to discriminate social signals, such as affective displays, using different sensory modalities is important for social communication. However, a major problem for understanding the evolution and integration of multimodal signals is determining how humans and animals attend to different sensory modalities, and these different modalities contribute to the perception and categorization of social signals. Using a matching-to-sample procedure, chimpanzees discriminated videos of conspecifics' facial expressions that contained only auditory or only visual cues by selecting one of two facial expression photographs that matched the expression category represented by the sample. Other videos were edited to contain incongruent sensory cues, i.e., visual features of one expression but auditory features of another. In these cases, subjects were free to select the expression that matched either the auditory or visual modality, whichever was more salient for that expression type. Results showed that chimpanzees were able to discriminate facial expressions using only auditory or visual cues, and when these modalities were mixed. However, in these latter trials, depending on the expression category, clear preferences for either the visual or auditory modality emerged. Pant-hoots and play faces were discriminated preferentially using the auditory modality, while screams were discriminated preferentially using the visual modality. Therefore, depending on the type of expressive display, the auditory and visual modalities were differentially salient in ways that appear consistent with the ethological importance of that display's social function.

	Title	Picture-object recognition in pigeons: evidence of representational insight in a visual categorization task using a complementary information procedure			Type	Journal Article
	Year	2006	Publication	Journal of Experimental Psychology. Animal Behavior Processes	Abbreviated Journal	J Exp Psychol Anim Behav Process
	Volume	32	Issue	2	Pages	190-195
	Keywords	Animals; Classification; Cognition; Columbidae; Discrimination Learning; Form Perception; Generalization (Psychology); Humans; Perceptual Closure; Photic Stimulation; Photography; *Recognition (Psychology)
	Abstract	Success in tasks requiring categorization of pictorial stimuli does not prove that a subject understands what the pictures stand for. The ability to achieve representational insight is by no means a trivial one because it exceeds mere detection of 2-D features present in both the pictorial images and their referents. So far, evidence for such an ability in nonhuman species is weak and inconclusive. Here, the authors report evidence of representational insight in pigeons. After being trained on pictures of incomplete human figures, the birds responded significantly more to pictures of the previously missing parts than to nonrepresentative stimuli, which demonstrates that they actually recognized the pictures' representational content.

	Title	Play signaling and the perception of social rules by juvenile 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	149-159
	Keywords	Age Factors; Animals; Behavior, Animal; Female; Male; Pan troglodytes; Play and Playthings; Recognition (Psychology); Signal Detection (Psychology); *Social Perception
	Abstract	Prescriptive social rules are enforced statistical regularities. The authors investigated whether juvenile chimpanzees (Pan troglodytes) recognize and use enforced statistical regularities to guide dyadic play behavior. They hypothesized (a) that proximity of adults, especially mothers of younger play partners, to play bouts will increase the play signaling of older partners and (b) that when juvenile-juvenile play bouts occur in proximity to adults, older partners will play at a lower intensity than when no adults are present. They found that older and younger partners increase their play signaling in the presence of the mothers of younger partners, particularly as the intensity of play bouts increases. In contrast to their hypothesis, older partners played more roughly when the mothers of younger partners were in proximity. These results suggest that juvenile chimpanzees increase play signaling to prevent termination of the play bouts by mothers of younger partners.

	Title	Reciprocal recognition of sifaka ( Propithecus verreauxi verreauxi) and redfronted lemur ( Eulemur fulvus rufus) alarm calls			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	1	Pages	45-52
	Keywords	Animals; Arousal; Escape Reaction; Female; Lemuridae/physiology/psychology; Male; Papio; Recognition (Psychology); Strepsirhini/physiology/psychology; Tape Recording; *Vocalization, Animal
	Abstract	Redfronted lemurs ( Eulemur fulvus rufus) and Verreaux's sifakas ( Propithecus verreauxi verreauxi) occur sympatrically in western Madagascar. Both species exhibit a so-called mixed alarm call system with functionally referential alarm calls for raptors and general alarm calls for carnivores and raptors. General alarm calls also occur in other contexts associated with high arousal, such as inter-group encounters. Field playback experiments were conducted to investigate whether interspecific recognition of alarm calls occurs in both species, even though the two species rarely interact. In a crossed design, redfronted lemur and sifaka alarm calls were broadcast to individuals of both species, using the alarm call of chacma baboons ( Papio cynocephalus) as a control. Both species responded with appropriate escape strategies and alarm calls after playbacks of heterospecific aerial alarm calls. Similarly, they reacted appropriately to playbacks of heterospecific general alarm calls. Playbacks of baboon alarm calls elicited no specific responses in either lemur species, indicating that an understanding of interspecific alarm calls caused the responses and not alarm calls in general. Thus, the two lemur species have an understanding of each other's aerial as well as general alarm calls, suggesting that even in species that do not form mutualistic associations and rarely interact, common predator pressure has been sufficient for the development of heterospecific call recognition.

	Title	Response of female cuttlefish Sepia officinalis (Cephalopoda) to mirrors and conspecifics: evidence for signaling in female cuttlefish			Type	Journal Article
	Year	2006	Publication	Animal cognition	Abbreviated Journal	Anim. Cogn.
	Volume	9	Issue	2	Pages	151-155
	Keywords	Analysis of Variance; Animal Communication; Animals; Bias (Epidemiology); Female; Male; Pigmentation/physiology; Recognition (Psychology)/physiology; Sepia/physiology; Visual Perception/*physiology
	Abstract	Cuttlefish have a large repertoire of body patterns that are used for camouflage and interspecific signaling. Intraspecific signaling by male cuttlefish has been well documented but studies on signaling by females are lacking. We found that females displayed a newly described body pattern termed Splotch toward their mirror image and female conspecifics, but not to males, prey or inanimate objects. Female cuttlefish may use the Splotch body pattern as an intraspecific signal, possibly to reduce agonistic interactions. The ability of females to produce a consistent body pattern in response to conspecifics and mirrors suggests that they can recognize same-sex conspecifics using visual cues, despite the lack of sexual dimorphism visible to human observers.

	Title	Sex categorization of conspecific pictures in Japanese monkeys (Macaca fuscata)			Type	Journal Article
	Year	2006	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	9	Issue	3	Pages	183-191
	Keywords	Animals; Conditioning, Operant; Discrimination (Psychology); Female; Generalization (Psychology); Macaca/psychology; Male; Pattern Recognition, Visual; Photography; Recognition (Psychology); *Sex Characteristics
	Abstract	We investigated whether monkeys discriminate the sex of individuals from their pictures. Whole-body pictures of adult and nonadult monkeys were used as stimuli. Two male Japanese monkeys were trained for a two-choice sex categorization task in which each of two choice pictures were assigned to male and female, respectively. Following the training, the monkeys were presented with novel monkey pictures, and whether they had acquired the categorization task was tested. The results suggested that while monkeys discriminate between the pictures of adult males and females, discrimination of nonadult pictures was difficult. Partial presentations of the pictures showed that conspicuous and sexually characteristic parts (i.e., underbellies including male scrotums or breasts including female nipples) played an important role in the sex categorization.

	Title	Social intelligence in the spotted hyena (Crocuta crocuta)			Type	Journal Article
	Year	2007	Publication	Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences	Abbreviated Journal	Philos Trans R Soc Lond B Biol Sci
	Volume	362	Issue	1480	Pages	523-538
	Keywords	Anatomy, Comparative; Animals; Brain/anatomy & histology; Cercopithecinae/anatomy & histology/physiology; Decision Making/physiology; Hyaenidae/anatomy & histology/physiology; Intelligence; Recognition (Psychology); Social Behavior; Species Specificity
	Abstract	If the large brains and great intelligence characteristic of primates were favoured by selection pressures associated with life in complex societies, then cognitive abilities and nervous systems with primate-like attributes should have evolved convergently in non-primate mammals living in large, elaborate societies in which social dexterity enhances individual fitness. The societies of spotted hyenas are remarkably like those of cercopithecine primates with respect to size, structure and patterns of competition and cooperation. These similarities set an ideal stage for comparative analysis of social intelligence and nervous system organization. As in cercopithecine primates, spotted hyenas use multiple sensory modalities to recognize their kin and other conspecifics as individuals, they recognize third-party kin and rank relationships among their clan mates, and they use this knowledge adaptively during social decision making. However, hyenas appear to rely more intensively than primates on social facilitation and simple rules of thumb in social decision making. No evidence to date suggests that hyenas are capable of true imitation. Finally, it appears that the gross anatomy of the brain in spotted hyenas might resemble that in primates with respect to expansion of frontal cortex, presumed to be involved in the mediation of social behaviour.

	Title	The monkey in the mirror: hardly a stranger			Type	Journal Article
	Year	2005	Publication	Proceedings of the National Academy of Sciences of the United States of America	Abbreviated Journal	Proc. Natl. Acad. Sci. U.S.A.
	Volume	102	Issue	32	Pages	11140-11147
	Keywords	Analysis of Variance; Animals; Cebus/physiology; Discrimination (Psychology); Empathy; Female; Male; Observation; Recognition (Psychology); Self Concept; Sex Factors
	Abstract	It is widely assumed that monkeys see a stranger in the mirror, whereas apes and humans recognize themselves. In this study, we question the former assumption by using a detailed comparison of how monkeys respond to mirrors versus live individuals. Eight adult female and six adult male brown capuchin monkeys (Cebus apella) were exposed twice to three conditions: (i) a familiar same-sex partner, (ii) an unfamiliar same-sex partner, and (iii) a mirror. Females showed more eye contact and friendly behavior and fewer signs of anxiety in front of a mirror than they did when exposed to an unfamiliar partner. Males showed greater ambiguity, but they too reacted differently to mirrors and strangers. Discrimination between conditions was immediate, and blind coders were able to tell the difference between monkeys under the three conditions. Capuchins thus seem to recognize their reflection in the mirror as special, and they may not confuse it with an actual conspecific. Possibly, they reach a level of self-other distinction intermediate between seeing their mirror image as other and recognizing it as self.
