Comparing apples to manzanas and oranges to naranjas
The valid assessment of vocabulary development in dual‐language‐learning infants is critical to developmental science. We developed the Dual Language Learners English‐Spanish (DLL‐ES) Inventories to measure vocabularies of U.S. English‐Spanish DLLs. The inventories provide translation equivalents for all Spanish and English items on Communicative Development Inventory (CDI) short forms; extended inventories based on CDI long forms; and Spanish la…
From ‘ah’ to ‘bah’
Social feedback is a driving force for speech development. A recent study provided a key finding to explain how contingent responses influence developmental change: infant speech-related vocalizations are contingent on responses to prior speech-related vocalizations (Warlaumont et al. , 2014). However, the study did not distinguish between different speech-related vocalizations, vowel-like (V) and consonant–vowel (CV) vocalizations, which is impo…
She is looking at me! Shall I share?’ How Chinese and American preschoolers respond to eye gaze during sharing
Previous research shows that the recipient's verbal communication about desires increases young children's sharing behavior. The current study examined how an adult partner's non‐verbal communication through eye gaze influenced sharing behavior in children from different cultures. We presented one hundred forty‐six 3‐ to 5‐year‐old American and Chinese children with a Dictator Game, in which they were asked to distribute resources between themsel…
Toys that squeak
Given the dependent nature of parent–infant interactions necessary for language development, it is important to understand how context may influence these interactions. This study examines how contextual variables influence communicative, cognitive and social measures of parent–infant interactions. Specifically, how do feedback toys and traditional toys associate with important parent and child measures necessary for learning and development? Her…
The Effect of Social Responsiveness on Infants' Object‐Directed Imitation
Previous research has demonstrated that social interactions underlie the development of object‐directed imitation. For example, infants differentially learn object action sequences from a live social partner compared to a social partner over a video monitor; however, what is not well understood is what aspects of social interactions influence social learning. Previous studies have found variable influences of different types of caregiver responsi…
The Value of Vocalizing
The interaction between infant's communicative competence and responsiveness of caregivers facilitates the transition from prelinguistic to linguistic communication. It is thus important to know how infants' communicative behavior changes in relation to different caregiver responses; furthermore, how infants' modification of communicative behavior relates to language outcomes. We investigated 39 10‐month‐old infants' communication as a function o…
Caregivers provide more labeling responses to infants' pointing than to infants' object-directed vocalizations
Existing studies have observed a robust relationship between infants' pointing gestures and language outcomes. By contrast, infants' overall vocal production is not related to language outcomes. One possible explanation for the association between pointing and language is that pointing gestures, as compared to vocalizations, may elicit more verbal responses from social partners that are facilitative for language learning. To test this, we observe…
Infants’ prelinguistic communicative acts and maternal responses
Infant–parent interactions are bidirectional; therefore, it is important to understand how infants’ communicative behavior elicits variable responses from caregivers and, in turn, how infants’ behavior varies with caregivers’ responses; furthermore, how these moment-to-moment interactive behaviors relate to later language development. The current study addressed these concerns by observing 10- to 13-month-old infants’ interactions with their moth…
Maternal Responsiveness and the Development of Directed Vocalizing in Social Interactions
For effective communication, infants must develop the phonology of sounds and the ability to use vocalizations in social interactions. Few studies have examined the development of the pragmatic use of prelinguistic vocalizations, possibly because gestures are considered hallmarks of early pragmatic skill. The current study investigated infant vocal production and maternal responsiveness to examine the relationship between infant and maternal beha…
Male dominance and reproductive success in wild white‐faced capuchins ( Cebus capucinus ) at Lomas Barbudal, Costa Rica
Theory and a growing body of empirical evidence suggest that higher ranking males experience reproductive advantages in group‐living mammals. White‐faced capuchins ( Cebus capucinus ) exhibit an interesting social system for investigating the relationship between dominance and reproductive success (RS) because they live in multimale multifemale social groups, in which the alpha males can have extraordinarily long tenures (i.e. they coreside with …

Acoustic Analysis and Contextual Description of Food-Associated Calls in White-Faced Capuchin Monkeys (Cebus capucinus)
Violent coalitionary attacks and intraspecific killing in wild white-faced capuchin monkeys ( Cebus capucinus )
Interspecific Interactions Between Cebus capucinus and Other Species
Social Conventions in Wild White-faced Capuchin Monkeys
Ten researchers collaborated in a longterm study of social conventions in wild whitefaced capuchin monkeys, involving examination of a 19,000hour combined data set collected on 13 social groups at four study sites in Costa Rica over a 13year period. Five behavior patterns qualified as social traditions, according to the studys criteria: handsniffing, sucking of body parts, and three types of games. Some conventions were independently invented in …
Contexts and behavioral correlates of trill vocalizations in wild white‐faced capuchin monkeys ( Cebus capucinus )
Primate vocalizations that appear to occur independently of specific contexts typically are considered to be contact calls. However, results from several recent studies indicate that these calls function to facilitate social interactions. White‐faced capuchin monkeys ( Cebus capucinus ) emit a high‐frequency vocalization, termed a “trill,” in social interactions and during travel. In this study, immatures emitted most trills, but adult females al…
Cross‐site differences in foraging behavior of white‐faced capuchins ( Cebus capucinus )
Researchers have identified a variety of cross‐site differences in the foraging behavior of free‐ranging great apes, most notably among chimpanzees ( Pan troglodytes ) and more recently orangutans ( Pongo pygmaeus ), that are not due to obvious genetic or ecological differences. These differences are often referred to as “traditions.” What is not known is whether this high level of interpopulation variation in behavior is limited to hominoids. In…
Dynamics of Female–Female Relationships in Wild Cebus capucinus
Sexual Dimorphism, the Operational Sex Ratio, and the Intensity of Male Competition in Polygynous Primates
Male mating competition is generally regarded to account for sexual dimorphism in body size, but levels of sexual dimorphism do not appear to be associated with the intensity of intrasexual selection in polygynous mammals. In contrast, observations of accentuated dimorphism in certain taxa and in large species are consistent with nonadaptive explanations for the evolution of sexual size dimorphism based on phylogenetic inertia and allometry. Here…
Number of males in primate groups
Primate social groups frequently contain multiple males. Male group size has been hypothesized to result from male mating competition, but the selective factors responsible for the evolution of multimale groups are unclear. Short breeding seasons create situations that are not conducive for single males to monopolize mating access to females, and may therefore favor the formation of large male groups. Alternatively, since the costs of mate defens…
Selection for acoustic individuality within the vocal repertoire of wild chimpanzees
Species and sex differences in the screams of chimpanzees and bonobos
Dialects in wild chimpanzees
Chimpanzees emit a loud, species‐typical long distance call known as the pant hoot. Geographic variation between the pant hoots of chimpanzees living in two neighboring populations, the Mahale Mountains and Gombe Stream National Parks, Tanzania, was examined. Analysis of six acoustic features revealed subtle differences in the way chimpanzees from the two populations called. Individuals from the Mahale study site uttered one section of their pant…
