“…Certainly, the communicative abilities expressed by captive apes differ from those reported in wild subjects (see above “Discussion”) but the diverse rearing experiences of the Yerkes population do not appear to have any direct influence on the production and elaboration of signaling within the methodological and procedural constraints of this study. However, the subjects in this study were not home-raised or language-trained—there are qualitative differences in communicative signaling between apes that have been cross-fostered and institutionalized apes, like those in the present study (see Call and Tomasello 1994; Kellogg 1968; Leavens 2004; Leavens et al 2005b, 2008b, 2009; Racine et al 2008; for discussion). We found no substantive differences in signaling behavior between institutionalized chimpanzees raised in peer cohorts, raised by their mothers, or taken from the wild prior to the 1970s and subsequently institutionalized.…”

Many studies have shown that apes and monkeys are adept at cross-modal matching tasks requiring the subject to identify objects in one modality when information regarding those objects has been presented in a different modality. However, much less is known about non-human primates' production of multimodal signaling in communicative contexts. Here, we present evidence from a study of 110 chimpanzees demonstrating that they select the modality of communication in accordance with variations in the attentional focus of a human interactant, which is consistent with previous research. In each trial, we presented desirable food to one of two chimpanzees, turning midway through the trial from facing one chimpanzee to facing the other chimpanzee, and documented their communicative displays, as the experimenter turned towards or away from the subjects. These chimpanzees varied their signals within a context-appropriate modality, displaying a range of different visual signals when a human experimenter was facing them and a range of different auditory or tactile (attention-getting) signals when the human was facing away from them; this finding extends previous research on multimodal signaling in this species. Thus, in the impoverished circumstances characteristic of captivity, complex signaling tactics are nevertheless exhibited by chimpanzees, suggesting continuity in intersubjective psychological processes in humans and apes.

“…The importance of caregiver recognition in the establishment of later social relationships has been described in several species including several birds (Fabricius, 1991;Immelmann, 1975;Lorenz, 1970;Ten Cate, 1985;Vos, 1995), rats (Fillion & Blass, 1986;Moore et al, 1996); sheep and goats (Kendrick et al, 1998;Kendrick, Haupt, Hinton, Broard, & Skinner, 2001); and nonhuman primates (Fujita, 1993;Kellogg, 1968). Cross-fostering studies in many species of birds (Fabricius, 1991;Immelmann, 1975;Lorenz, 1970;Ten Cate, 1985;Vos, 1995), and between sheep and goats FIGURE 4 Partner preference in male rats with and without sexual experience following neonatal handling.…”

Neonatal handling is an experimental procedure used to understand how early-life adversity can negatively affect neurobehavioral development and place animals on a pathway to pathology. Decreased preference for the maternal odor during infancy is one of many behavioral deficits induced by neonatal handling. Here, we hypothesize that deficits in maternal odor preference may interfere with partner preference in the adult. To test this hypothesis, we assessed infant maternal odor preference and adult partner preference in different reproductive stages in both male and female rats that received neonatal handling. Our results indicate that only neonatally handled females present deficits in maternal odor preference during infancy, but both male and females present deficits in adult partner preference. However, sexual experience was effective in rescuing partner preference deficits in males. These results indicate that, considering infant and adult social interactions, females are more susceptible to the effects of neonatal handling than males.

“…The earliest recorded attempts began in 1932 with Jacobsen, Jacobsen, and Yoshioka (Kellogg, 1968), who tried to teach Alpha, a female chimpanzee, beginning when she was a few days of age, for a period of one year. In 1932, Kellogg and Kellogg (1968) attempted to teach a female chimp, Gua, from the age of 71/2 months for 9 months. She was reared at home along with one child as a control.…”

“…The Hayes's taught Viki to say "momma" by manipulating her lips. Kellogg (1968) reported that "momma," "poppa," "cup" and possibly "up" represent the acme of chimpanzee achievement in the production of human speech sounds. The words were learned only with the greatest of difficulty, and even after the animal could reproduce them, the words were sometimes confused and used incorrectly.…”
