Description
An account of the resource
Primate hands can be classified into two broad categories on the basis of ray proportions and other features. Ectaxonic hands are characterized by a longer fourth ray and are found in most strepsirhines. Most haplorhines possess mesaxonic hands which are characterized by a longer third ray. Preuschoft et al. ([1993] in H. Preuschoft and D.J. Chivers (eds.): Hands of Primates. Berlin: Springer-Verlag, pp. 21-30) proposed a biomechanical model which predicts that, during quadrupedalism, a mesaxonic hand should be held in a more neutral position with respect to the forearm, whereas an ectaxonic hand should be more ulnarly deviated. The relation between hand positioning and the mesaxony/ectaxony categorization is investigated for 27 primate taxa. Videotapes were recorded for each species walking quadrupedally on arboreal supports. Several species were also videotaped during ground quadrupedalism. The degree of deviation of the hand relative to the substrate and the grips utilized were quantified for 18 species from the videotapes. Primates with mesaxonic hands use deviated hand positions and grips, especially when walking quadrupedally on small poles. Several species with ectaxonic hands use neutral hand positions and grips when walking quadrupedally on similar supports. Also, several primates, with either ectaxonic or mesaxonic hands, display a combination of deviated hand positions and grips when on arboreal substrates and neutral hand positioning when on the ground. The statistical results indicate that hand positioning during quadrupedal walking is more variable than expected based on the mesaxony/ectaxony classification. Furthermore, radiographic data suggest that primates evolved at least two different mechanisms of hand ulnar deviation.

Description
An account of the resource
The distribution of peak vertical forces between the forelimbs and the hind limbs is one of the key traits distinguishing primate quadrupedal locomotion from that of other mammals. Whereas most mammals generate greater peak vertical forelimb forces, primates generate greater peak vertical hind limb forces. At the ultimate level, hind limb dominance in limb force distribution is typically interpreted as an adaptation to facilitate fine-branch arboreality. However, the proximate biomechanical bases for primate limb force distribution remain controversial. Three models have been previously proposed. The Center of Mass (COM) Position model attributes primates' unique mode of limb loading to differences in the position of the whole-body COM relative to the hands and feet. The Active Weight Shift model asserts that primates actively redistribute body weight to their hind limbs by pitching the trunk up via the activation of hind limb retractor muscles. Finally, the Limb Compliance model argues that primates selectively mitigate forelimb forces by maintaining a compliant forelimb and a flat shoulder trajectory. Here, a detailed dataset of ontogenetic changes in morphology and locomotor mechanics in Bolivian squirrel monkeys (Saimiri boliviensis) was employed as a model system to evaluate each of these proposed models in turn. Over the first 10 months of life, squirrel monkeys transitioned from forelimb dominant infants to hind limb dominant juveniles, a change that was precipitated by decreases in peak vertical forelimb forces and increases in peak vertical hind limb forces. Results provided some support for all three of the models, although the COM Position and Active Weight Shift models were most strongly supported by the data. Overall, this study suggests that primates may use a variety of biomechanical strategies to achieve hind limb dominance in limb force distribution.

Description
An account of the resource
The ability to perceive nonverbal facial cues was tested in 30 White, middle-class females. Pre- and post-menses responses of 15 subjects diagnosed as having Premenstrual Tension Syndrome (PMS) were compared to the responses of age-matched controls. Each subject was asked to interpret videotaped facial cues of individuals engaged in a gambling task. Interpretive ability fluctuated during the menstrual cycle and was significantly impaired during the premenstrual phase.
