In most research on the early ontogeny of sympathy, young children are presented with an overtly distressed person and their responses are observed. In the current study, the authors asked whether young children could also sympathize with a person to whom something negative had happened but who was expressing no emotion at all. They showed 18- and…

Two studies investigated whether young children are selectively prosocial toward others, based on the others' moral behaviors. In Study 1 (N = 54), 3-year-olds watched 1 adult (the actor) harming or helping another adult. Children subsequently helped the harmful actor less often than a third (previously neutral) adult, but helped the helpful and…

We investigate the development of word order in German children's spontaneous production of complement clauses. From soon after their second birthday, young German children use both verb final complements with complementizers and verb-second complements without complementizers. By their third birthday they use both kinds of complement clauses with…

Many studies have established that children tend to exclude objects for which they already have a name as potential referents of novel words. In the current study we asked whether this exclusion can be triggered by social-pragmatic context alone without pre-existing words as blockers. Two-year-old children watched an adult looking at a novel…

In two studies we investigated 2-year-old children's answers to predicate-focus questions depending on the preceding context. Children were presented with a successive series of short video clips showing transitive actions (e.g., frog washing duck) in which either the action (action-new) or the patient (patient-new) was the changing, and therefore…

From a surprisingly young age, children are capable of a level of sophisticated social understanding and interaction for which they are rarely given credit. Indeed, beginning as early as 9 months, children are gaining the skills needed to become active members of the unique culture and society into which they are born. This article explores the…

English and German children aged 2 years 4 months and 4 years heard both novel and familiar verbs in sentences whose form was grammatical, but which mismatched the event they were watching (e.g., "The frog is pushing the lion", when the lion was actually the "agent" or "doer" of the pushing). These verbs were then elicited in new sentences. All…

When adults make a joint commitment to act together, they feel an obligation to their partner. In 2 studies, the authors investigated whether young children also understand joint commitments to act together. In the first study, when an adult orchestrated with the child a joint commitment to play a game together and then broke off from their joint…

In two studies, the authors investigated 2- and 3-year-old children's awareness of the normative structure of conventional games. In the target conditions, an experimenter showed a child how to play a simple rule game. After the child and the experimenter had played for a while, a puppet came (controlled by a 2nd experimenter), asked to join in,…

This paper investigates the development of relative clauses in the speech of one German-speaking child aged 2 ; 0 to 5 ; 0. The earliest relative clauses we found in the data occur in topicalization constructions that are only a little different from simple sentences: they contain a single proposition, express the actor prior to other…

Using a preferential looking methodology with novel verbs, Gertner, Fisher and Eisengart (2006 ) found that 21-month-old English children seemed to understand the syntactic marking of transitive word order in an abstract, verb-general way. In the current study we tested whether young German children of this same age have this same understanding.…

Classically, infants are thought to point for 2 main reasons: (a) They point imperatively when they want an adult to do something for them (e.g., give them something; "Juice!"), and (b) they point declaratively when they want an adult to share attention with them to some interesting event or object ("Look!"). Here we demonstrate the existence of…

Twenty-two- and 27-month-old children were tested for their understanding of pretending as a specific intentional action form. Pairs of superficially similar behaviors--pretending to perform an action and trying to perform that action--were demonstrated to children. The 27-month-olds, and to some degree the 22-month-olds, showed in their responses…

In 3 studies, young children were tested for their understanding of pretend actions. In Studies 1 and 2, pairs of superficially similar behaviors were presented to 26- and 36-month-old children in an imitation game. In one case the behavior was marked as trying (signs of effort), and in the other case as pretending (signs of playfulness).…

Compared the abilities of 3 mother-reared and 3 human-raised (enculturated) chimpanzees and 16 human toddlers to imitatively learn novel actions on objects. Found that mother-reared chimpanzees were poorer imitators than both enculturated chimpanzees and human children, who did not differ from one another in imitative learning. On time delay…
