Significance: Although much research has been devoted to the acquisition of number words, relatively little is known about the acquisition of other expressions of quantity. We propose that the order of acquisition of quantifiers is related to features inherent to the meaning of each term. Four specific dimensions of the meaning and use of quantifiers are found to capture robust similarities in the order of acquisition of quantifiers in similar ways across 31 languages, representing 11 language types.

Several neuroimaging studies point to a key role of the dorsomedial prefrontal cortex (dmPFC) in the formation of socially relevant impressions. In 3 different experiments, participants were required to form socially relevant impressions about other individuals on the basis of text descriptions of their social behaviors, and to decide whether a face alone, a trait adjective (e.g., “selfish”), or a face presented with a trait adjective was consistent or inconsistent with the impression they had formed. Before deciding whether the target stimulus matched the impression they had previously formed, participants received transcranial magnetic stimulation (TMS) over the dmPFC, the inferior frontal gyrus (IFG, also implicated in social impression formation), or over a control site (vertex). Results from the 3 experiments converged in showing that interfering with dmPFC activity significantly delayed participants in responding whether a face-adjective pair was consistent with the impression they had formed. No effects of TMS were observed following stimulation of the IFG or when evaluations had to be made on faces or trait adjectives presented alone. Our findings critically extend previous neuroimaging evidence by indicating a causal role of the dmPFC in creating coherent impressions based on the integration of face and verbal description of social behaviors.

This study examines the comprehension of relative clauses by Chinese-speaking children, and evaluates the validity of the predictions of the Dependency Locality Theory (Gibson, 1998, 2000) and the Relativized Minimality approach (Friedmann, Belletti & Rizzi, 2009). One hundred and twenty children from three to eight years of age were tested by using a character–sentence matching task. We found a preference for subject relative clauses that persists as children grow older. This preference is predicted by the Relativized Minimality approach, but not by the Dependency Locality Theory. In addition, we observed a fine-grained class of errors in comprehension. We discuss it in the light of the head-final status of Chinese relative clauses.

In three experiments, we investigate whether speakers tend to perseverate in the assignment of emphasis to concepts with particular thematic roles across utterances. Participants matched prime sentences involving clefts (e.g., Het is de cowboy die hij slaat, “It is the cowboy that he is hitting”) to pictures and then described unrelated transitive events. Participants were more likely to produce a passive after a cleft that emphasised the patient than after a cleft that emphasised the agent. Because prime and target sentences are syntactically unrelated, our study demonstrated nonsyntactic structural priming. We propose that speakers use such priming to facilitate the construction of coherent discourse.
