A comparison of activity patterns for captive Propithecus tattersalli and Propithecus coquereli.
(Zoo Biol, 2016-03)The activity patterns and social interactions of two species of captive sifaka were observed during a 2-year period. Allogrooming was not observed in golden-crowned sifaka and they spent significantly more time resting than ... -
Assessing visual requirements for social context-dependent activation of the songbird song system.
(Proc Biol Sci, 2009-01-22)Social context has been shown to have a profound influence on brain activation in a wide range of vertebrate species. Best studied in songbirds, when males sing undirected song, the level of neural activity and expression ... -
Considering the role of social dynamics and positional behavior in gestural communication research.
(Am J Primatol, 2013-09)While the hominin fossil record cannot inform us on either the presence or extent of social and cognitive abilities that may have paved the way for the emergence of language, studying non-vocal communication among our closest ... -
Developmental cascades of peer rejection, social information processing biases, and aggression during middle childhood.
(Dev Psychopathol, 2010-08)This study tested a developmental cascade model of peer rejection, social information processing (SIP), and aggression using data from 585 children assessed at 12 time points from kindergarten through Grade 3. Peer rejection ... -
Differences in the early cognitive development of children and great apes.
(Dev Psychobiol, 2014-04)There is very little research comparing great ape and human cognition developmentally. In the current studies we compared a cross-sectional sample of 2- to 4-year-old human children (n=48) with a large sample of chimpanzees ... -
Direct and indirect reputation formation in nonhuman great apes (Pan paniscus, Pan troglodytes, Gorilla gorilla, Pongo pygmaeus) and human children (Homo sapiens).
(J Comp Psychol, 2013-02)Humans make decisions about when and with whom to cooperate based on their reputations. People either learn about others by direct interaction or by observing third-party interactions or gossip. An important question is ... -
Dominance, politics, and physiology: voters' testosterone changes on the night of the 2008 United States presidential election.
(PLoS One, 2009-10-21)BACKGROUND: Political elections are dominance competitions. When men win a dominance competition, their testosterone levels rise or remain stable to resist a circadian decline; and when they lose, their testosterone levels ... -
Dopamine receptors in a songbird brain.
(J Comp Neurol, 2010-03-15)Dopamine is a key neuromodulatory transmitter in the brain. It acts through dopamine receptors to affect changes in neural activity, gene expression, and behavior. In songbirds, dopamine is released into the striatal song ... -
Early social exposure in wild chimpanzees: mothers with sons are more gregarious than mothers with daughters.
(Proc Natl Acad Sci U S A, 2014-12-23)In many mammals, early social experience is critical to developing species-appropriate adult behaviors. Although mother-infant interactions play an undeniably significant role in social development, other individuals in ... -
Effects of sub-chronic methylphenidate on risk-taking and sociability in zebrafish (Danio rerio).
(Naunyn-Schmiedeberg's archives of pharmacology, 2020-08)Attention deficit hyperactive disorder (ADHD) is the most common psychiatric disorder in children affecting around 11% of children 4-17 years of age (CDC 2019). Children with ADHD are widely treated with stimulant medications ... -
Genetic origins of social networks in rhesus macaques.
(Scientific reports, 2013-01-09)Sociality is believed to have evolved as a strategy for animals to cope with their environments. Yet the genetic basis of sociality remains unclear. Here we provide evidence that social network tendencies are heritable in ... -
Integrating simultaneous prosocial and antisocial behavior into theories of collective action.
(Sci Adv, 2016-03)Trust and cooperation constitute cornerstones of common-pool resource theory, showing that "prosocial" strategies among resource users can overcome collective action problems and lead to sustainable resource governance. ... -
Interactions between social/ behavioral factors and ADRB2 genotypes may be associated with health at advanced ages in China.
(BMC Geriatr, 2013-09-09)BACKGROUND: Existing literature indicates that ADRB2 gene is associated with health and longevity, but none of previous studies investigated associations of carrying the ADRB2 minor alleles and interactions between ADRB2 ... -
Mine or yours? Development of sharing in toddlers in relation to ownership understanding.
(Child Dev, 2013-05)To examine early developments in other-oriented resource sharing, fifty-one 18- and 24-month-old children were administered 6 tasks with toys or food that could be shared with an adult playmate who had none. On each task ... -
Pregnancy, alcohol intake, and intimate partner violence among men and women attending drinking establishments in a Cape Town, South Africa township.
(J Community Health, 2012-02)The highest rates of fetal alcohol syndrome worldwide can be found in South Africa. Particularly in impoverished townships in the Western Cape, pregnant women live in environments where alcohol intake during pregnancy has ... -
Rapid behavioral and genomic responses to social opportunity.
(PLoS Biol, 2005-11)From primates to bees, social status regulates reproduction. In the cichlid fish Astatotilapia (Haplochromis) burtoni, subordinate males have reduced fertility and must become dominant to reproduce. This increase in sexual ... -
Relational Mobility Predicts Faster Spread of COVID-19: A 39-Country Study.
(Psychological science, 2020-10)It has become increasingly clear that COVID-19 is transmitted between individuals. It stands to reason that the spread of the virus depends on sociocultural ecologies that facilitate or inhibit social contact. In particular, ... -
Role of the midbrain dopaminergic system in modulation of vocal brain activation by social context.
(Eur J Neurosci, 2007-06)In a well-studied model of social behaviour, male zebra finches sing directed song to court females and undirected song, used possibly for practice or advertisement. Although the two song types are similar, the level of ... -

Sexual selection and canine dimorphism in New World monkeys.
(Am J Phys Anthropol, 1988-11)Social and ecological factors are important in shaping sexual dimorphism in Anthropoidea, but there is also a tendency for body-size dimorphism and canine dimorphism to increase with increased body size (Rensch's rule) (Rensch: ...
