Mothers, environment, and ontogeny affect cognition

The book “Folk Physics for Apes” remains a fascinating book about the way one captive peer-group of chimpanzees understand the world in which they grew. However, the very special living conditions these seven individuals faced prevent any generalizations to the...

Home-enclosure-based behavioral and wireless neural recording setup for unrestrained rhesus macaques

Electrophysiological studies with behaving nonhuman primates often require the separation of animals from their social group as well as partial movement restraint to perform well-controlled experiments. When the research goal per se does not mandate constraining the animals' movements, there...

Trends and treatment approaches for complications in neuroscience experiments with monkey species

Our goal in this manuscript is to advance the assessment and treatment of monkey species in neuroscience research. We hope to begin a discussion and establish baseline data on how complications are identified and treated. We surveyed the neuroscience research...

Monkeying around: Non-human primate behavioural responses to humans reproducing their facial expressions

People are often observed mimicking animals' facial expressions in an attempt to communicate with them. However, to date, there is limited understanding of how animals respond to humans reproducing their facial displays, or if this type of human behaviour presents...

Initial compatibility during a “Speed-Dating” test predicts postpairing affiliation in titi monkeys (Plecturocebus cupreus)

Behavioral compatibility plays a critical role in shaping how potential mates interact with and evaluate each other and whether they choose to pursue a relationship. Compatibility is especially important for mate choice and relationship quality in pair-bonding species that form...

Urinary cytokine measurements do not reflect surgery-induced inflammation in rhesus macaques

Measurement of the health and disease status of free-ranging primates is often limited by a lack of available biomarkers of immune activation and inflammation that can be applied noninvasively via the measurement of urine or fecal samples. Here, we evaluate...

Room size and offspring presence impact pair-bonded primate affiliation

Primates live in a variety of social groupings and vary in the expression of species-typical behaviors depending upon social conditions. Coppery titi monkeys (Plecturocebus cupreus) are pair-bonding, territorial primates often used to study neurobiology and social behavior in captivity at...

The four Cs of psychological wellbeing: Lessons from three decades of computer-based environmental enrichment

Three decades ago, the Animal Welfare Act was amended to require researchers to provide environments that promoted the psychological, as well as the physical, wellbeing of nonhuman primates maintained for research purposes. We developed a computer-task paradigm with the goal...

The choice to access outdoor areas affects the behavior of great apes

Outdoor access is often cited as a critical component of appropriate housing for great apes in captivity, and although studies have shown that offering primates choices can improve welfare, choice to access specific areas has been empirically neglected. Behavioral data...

The psychology of control: Effects of control over supplementary light on welfare of marmosets

It is often argued that increasing the amount of control that animals have over various aspects of their environment has a positive effect on their welfare, despite limited empirical evidence. We gave 12 pairs of common marmosets (Master pairs) control...
