The last decade has seen a resurgence of interest in laterality of function in primates,
especially in hand use as it links to handedness and language in Homo sapiens. Manual …

Prosimians are the most distantly related primates to humans and are unique subjects for
studies of behavioral asymmetries. This chapter outlines the values of research from …

The purpose of this study was to assess the occurrence of manual laterality in Ateles
geoffroyi and in particular to test the influence of visual and tactual control on preferential …

Lateral preference was examined in spontaneous feeding actions in 2 troops of wild vervet
monkeys (Cercopithecus aethiops). Processing of 4 foods (termites, leaf shoots, sugarcane …

Sixteen sifakas (11 Propithecus verreauxi coquereli, 2 Propithecus verreauxi verreauxi form
majori, and 3 Propithecus tattersalli) were videotaped as they fed on leaves in an arboreal …

Behavioural asymmetries, once thought to be exclusively human, appear to be widespread
in vertebrates. A population-level bias should stem from natural selection and reflect a …

To robustly study zoo animal cognition and provide effective enrichment, we must provide
animals with carefully designed apparatus made from appropriate (safe, attractive, practical) …

A variety of mammalian species including prosimian and simian primates wrap their tails
around their bodies as a means of thermoregulation and for reasons of comfort during …

The purpose of this study was to assess the occurrence of lateral biases in the use of the
prehensile tail in Ateles geoffroyi. 24 spider monkeys were presented with three food …

Parrots are unusual in their relative brain size and apparent intelligence in captivity, but little
is known of their natural behavior. I studied a habituated flock of glossy black-cockatoos on …
