Existing work on the acquisition of polarity-sensitive expressions (PSIs) suggests that children show an early sensitivity to the restricted distribution of negative polarity items (NPIs), but may be delayed in the acquisition of positive polarity items (PPIs). However, past studies primarily targeted PSIs that are highly frequent in children's…

The present study examined cross-linguistic differences in morphological processing in the visual and auditory modality. French and German adults performed a visual and auditory lexical decision task that involved the same translation-equivalent items. The focus of the study was on nonwords, which were constructed in a way that made it possible to…

Children's lexical processing speed at 18 to 25 months of age has been linked to concurrent and later language abilities. In the current study, we extend this finding to children aged 36 months. Children (N = 126) participated in a lexical processing task in which they viewed two static images on noun trials (e.g., an ear of corn and a hat), or…

Contrastive focus, conveyed by prosodic cues, marks important information. Studies have shown that 6-year-olds learning English and Japanese can use contrastive focus during online sentence comprehension: focus used in a "contrastive context" facilitates the identification of a target referent (speeding up processing), whereas focus used…

Two eye-tracking experiments tested (a) whether L2 learners benefit from the consistency of input modality (auditory instead of written processing instruction [PI] training) and (b) whether they benefit from training using the same voice as the test voice. Results confirmed a robust effect of PI training on picture-selection accuracy, yet the…

We assessed 24-month-old infants' lexical processing efficiency for both novel and familiar words. Prior work documented that 19-month-olds successfully identify referents of familiar words (e.g., The dog is so little) as well as novel words whose meanings were informed only by the surrounding sentence (e.g., The vep is crying), but that the speed…

The present study investigated infants' knowledge about familiar nouns. Infants (n = 46, 12-20-month-olds) saw two-image displays of familiar objects, or one familiar and one novel object. Infants heard either a matching word (e.g. "foot' when seeing foot and juice), a related word (e.g. "sock" when seeing foot and juice) or a nonce…

Although it has been established that human beings process concrete and abstract words differently, it is still a matter of debate what factors contribute to this difference. Since concrete concepts are closely tied to sensory perception, perceptual experience seems to play an important role in their processing. The present study investigated the…

Research on early word learning reveals that verbs present a unique challenge. While English-acquiring 24-month-olds can learn novel verbs and extend them to new scenes, they perform better in rich linguistic contexts (when novel verbs appear with lexicalized noun phrases naming the event participants) than in sparser linguistic contexts…

Research has demonstrated that children use different strategies to infer a referent. One of these strategies is to use inflectional morphology. We present evidence that toddlers learning Spanish are capable of using gender word inflections to infer word reference. Thirty-month-olds were tested in a preferential looking experiment. Participants…
