	Title	Acquisition of a relative class concept by an African gray parrot (Psittacus erithacus): discriminations based on relative size			Type	Journal Article
	Year	1991	Publication	Journal of Comparative Psychology	Abbreviated Journal	J Comp Psychol
	Volume	105	Issue	3	Pages	286-294
	Keywords	Animals; Aptitude; Concept Formation; Discrimination Learning; Form Perception; Male; Mental Recall; Parrots; Size Perception; Vocalization, Animal
	Abstract	We report that an African gray parrot (Psittacus erithacus), Alex, responds to stimuli on a relative basis. Previous laboratory studies with artificial stimuli (such as pure tones) suggest that birds make relational responses as a secondary strategy, only after they have acquired information about the absolute values of the stimuli. Alex, however, after learning to respond to a small set of exemplars on the basis of relative size, transferred this behavior to novel situations that did not provide specific information about the absolute values of the stimuli. He responded to vocal questions about which was the larger or smaller exemplar by vocally labeling its color or material, and he responded “none” if the exemplars did not differ in size. His overall accuracy was 78.7%.

	Title	*Differential use of vocal and gestural communication by chimpanzees (Pan troglodytes) in response to the attentional status of a human (Homo sapiens)*			Type	Journal Article
	Year	2001	Publication	Journal of Comparative Psychology	Abbreviated Journal	J. Comp. Psychol.
	Volume	115	Issue	4	Pages	337-343
	Keywords	Animals; Attention; Communication Methods, Total; Female; Gestures; Humans; Male; Motivation; Pan troglodytes/psychology; Social Environment; Species Specificity; *Vocalization, Animal
	Abstract	This study examined the communicative behavior of 49 captive chimpanzees (Pan troglodytes), particularly their use of vocalizations, manual gestures, and other auditory- or tactile-based behaviors as a means of gaining an inattentive audience's attention. A human (Homo sapiens) experimenter held a banana while oriented either toward or away from the chimpanzee. The chimpanzees' behavior was recorded for 60 s. Chimpanzees emitted vocalizations faster and were more likely to produce vocalizations as their 1st communicative behavior when a human was oriented away from them. Chimpanzees used manual gestures more frequently and faster when the human was oriented toward them. These results replicate the findings of earlier studies on chimpanzee gestural communication and provide new information about the intentional and functional use of their vocalizations.

	Title	Vocalizations of rhesus (Macaca mulatta) and Japanese (M. fuscata) macaques cross-fostered between species show evidence of only limited modification			Type	Journal Article
	Year	1993	Publication	Developmental psychobiology	Abbreviated Journal	Dev Psychobiol
	Volume	26	Issue	7	Pages	389-406
	Keywords	Animals; Animals, Newborn; Behavior, Animal; Discrimination Learning; Environment; Female; Macaca; Macaca mulatta; Male; Sound Spectrography; *Vocalization, Animal
	Abstract	Two rhesus and two Japanese macaque infants were cross-fostered between species in order to study the effects of auditory experience on vocal development. Both the cross-fostered and normally raised control subjects were observed over the first 2 years of life and their vocalizations were tape-recorded. We classified 8053 calls by ear, placed each call in one of six acoustic categories, and calculated the rates at which different call-types were used in different social contexts. Species differences were found in the use of “coo” and “gruff” vocalizations among control subjects. Japanese macaques invariably produced coos almost exclusively. In contrast, rhesus macaques produced a mixture of coos and gruffs and showed considerable interindividual variation in the relative use of one call type or the other. Cross-fostered Japanese macaques adhered to their species-typical behavior, rarely using gruffs. Cross-fostered rhesus subjects also exhibited species-typical behavior in many contexts, but in some situations produced coos and gruffs at rates that were intermediate between those shown by normally raised animals of the two species. This outcome suggests that environmentally mediated modification of vocal behavior may have occurred, but that the resulting changes were quite limited.

	Title	Within-species variation in the development of ultrasonic signaling of preweanling rats			Type	Journal Article
	Year	1979	Publication	Developmental Psychobiology	Abbreviated Journal	Dev Psychobiol
	Volume	12	Issue	2	Pages	129-136
	Keywords	Animals; Animals, Newborn; Animals, Suckling; Body Weight; Cold/adverse effects; Environment; Genotype; Individuality; Object Attachment; Rats; Stress/physiopathology; Ultrasonics; *Vocalization, Animal
	Abstract	The development of litter and individual differences in the rate of ultrasonic signaling of neonatal rats was studied. Systematic variations among litters and individuals emerged, without differential treatment. These differences were not correlated with variations in general development as indexed by body weight. Two experiments using a cross-fostering design showed that litter differences developed independently of variations in postnatal environment. These results indicate that the variations among litters in ultrasound rate have a prenatal, possibly genetic, etiology and may represent reliable indicants of response to environmental stress.

	Title	Modification of reconciliation behavior through social experience: an experiment with two macaque species			Type	Journal Article
	Year	1993	Publication	Child development	Abbreviated Journal	Child Dev
	Volume	64	Issue	3	Pages	897-908
	Keywords	Aggression; Animals; Behavior, Animal; Female; Grooming; Macaca; Macaca mulatta; Male; Play and Playthings; Socialization; Vocalization, Animal
	Abstract	Reconciliation, defined as a friendly reunion between former opponents shortly after an aggressive encounter, is common in the stumptail macaque (Macaca arctoides) but rare in the rhesus macaque (M. mulatta). Juveniles of the two species were cohoused for 5 months, after which they were observed with conspecifics only. Control rhesus monkeys, matched in age and sex to the experimental subjects, went through the same procedure without exposure to the other species. A threefold increase in the proportion of reconciled fights was measured in the rhesus subjects. The difference emerged gradually during cohousing with the tutor species and was sustained following removal of this species. Other behavior, such as grooming and aggression, decreased over time. It is suggested that the social attitude of the subjects was affected through contact with a species characterized by a more relaxed dominance style.

	Title	Changes in visual responsiveness following intercollicular lesions and their effects on avoidance and attack			Type	Journal Article
	Year	1974	Publication	Brain, Behavior and Evolution	Abbreviated Journal	Brain Behav Evol
	Volume	10	Issue	4-5	Pages	400-424
	Keywords	Animals; Chickens; Humans; Male; Mutism; Superior Colliculi/*physiology; Tectum Mesencephali; Testosterone; Visual Fields; Vocalization, Animal
	Abstract	In the normal chick, conspicuous visual stimuli induce targetting and pecking together, with vocalization. All three are abolished by lesion of the intercollicular area (ICo) or of connections passing through its medial margin. After such lesions, chicks also cease to treat significant visual stimuli as if they were startling and exciting, and may delay response as a result. However, they are still able to recognise, orient accurately to, and respond appropriately to, a variety of complex visual stimuli (e.g. food grains, copulation object). In addition, they are little affected by strange surroundings. Lesion evidence suggests the mammalian subcollicular area to have similar functions to the ICo and to be homologous with it. A route (present in bird), which is well-known in mammals for its association with threat, defense and escape evoked by strange and frightening objects (amygdala-diencephalic periventricular system-central mesencephalic grey, A-DPS-CMG) is stimuli via the 2 ICo (subcollicular area). Two different mechanisms may be involved caudal to the ICo. One consists of tectal afferents which might modulate the evocation of targetting, pecking and other responses via the tectum. The other is the predorsal system of tectal efferents which may mediate such responses. Classical syndromes of tameness and unresponsiveness produced by various interruptions of the A-DPS-CMG route may depend on interruption of connections to these midbrain mechanisms. Attack is depressed by ICo lesions as one aspect of reduced responsiveness to conspicuous and startling visual stimuli. Avoidance, which is apparently mediated by a separate system, much as in Anura, is facilitated.
