Response patterns of bonnet macaques following up to 75 weeks of continuous access to social‐video and food rewards
Three individually housed bonnet macaque males were given 75 weeks of continuous access to a joystick task with a reward choice of either viewing live color video of a bonnet group or obtaining a banana‐flavored food treat. Here we report data for weeks 44–75 following a change in the stimulus group displayed in the video. The new stimulus group enhanced responding to the video for two subjects over the entire 32 weeks of this study, although the…
Location effects of social partner on experimental foraging in the squirrel monkey
The effect of social context on experimental foraging in squirrel monkeys ( Saimiri sciureus ) was investigated. The 12 subjects comprised six pairs in which strong social preference and attraction had been demonstrated during observations of a stable group. Individuals were first trained to discriminate spatially separated rich and poor foraging bins containing 75% and 25% of the food items, respectively, with their partners restrained equidista…
Location‐restricted dyadic interactions and maternal patterns
The purpose of this study was to determine the impact of infant restraint on dyadic interactions and maternal foraging patterns. Five bonnet macaque ( Macaca radiata ) mother‐infant dyads were observed under three conditions: high foraging demand for the mothers with nonrestrained contact between mothers and infants (HFD‐NRC), high foraging demand with restrained contact (HFD‐RC), and low foraging demand with restrained contact (LFD‐RC). In the r…

Allometry of primate hair density and the evolution of human hairlessness
Allometric analyses of hair densities in 23 anthropoid primate taxa reveal that increasingly massive primates have systematically fewer hairs per equal unit of body surface. Considering the absence of effective sweating in monkeys and apes, the negative allometry of relative hair density may represent an architectural adaptation to thermal constraints imposed by the decreasing ratios of surface area to volume in progressively massive primates. Ju…

Sexual behavior during successive ejaculations in bonnet and pigtail macaques
During tests of sexual behavior which permitted multiple ejaculations, male bonnet and pigtail macaques were found to differ on a number of traditionally defined behavioral parameters. Although pigtail tests were terminated by a more stringent criterion, they were longer in duration and more ejaculations were recorded than in the bonnet tests. Pigtail males required relatively more intromissions for initial ejaculations and somewhat fewer on succ…

Maturational variables influencing sexual posturing in infant monkeys
Responses to “Frustration” in One-Year-Old Infants
Qualitative and quantitative responses to a frustration situation in a sample of 1-year-old normal infants are described. The findings indicated considerable variation in the quality of affect and the span ofinterest. In 1 group of infants, negative affect developed in a relatively short period of time and resulted in disruption ofinterest; in another group of infants, no negative affect developed but instead, a shift in their focus ofinterestocc…
Variations in infant development and response to maternal loss in monkeys
Sustained physical contact between animals characterizes bonnet but not pigtail monkey groups. This pattern encourages maternal permissiveness and enhances social orientation in infants. Moreover, pigtail infants show depression and behavioral debilitation after maternal loss, whereas bonnets are often adopted by others and suffer minimal affective and behavioral changes
The Reaction to Separation in Infant Monkeys: Anaclitic Depression and Conservation-Withdrawal
The reaction to removal of the mother was studied in 4 group-living pigtail monkey infants. All showed distress, with 3 progressing to a state of deep depression similar to the anaclitic depression of human infants following separation, as described by Spitz. The only infant not showing deep depression was the offspring of the dominant female. The stages of reaction are seen as successive efforts at adaptation based on available response systems,…
