We examined if and when English-learning 17-month-olds would accommodate Japanese forms as labels for novel objects. In Experiment 1, infants (n = 22) who were habituated to Japanese word-object pairs looked longer at switched test pairs than familiar test pairs, suggesting that they had mapped Japanese word forms to objects. In Experiments 2 (n =…

When linguistic information alone does not clarify a speaker's intended meaning, skilled communicators can draw on a variety of cues to infer communicative intent. In this paper, we review research examining the developmental emergence of preschoolers' sensitivity to a communicative partner's perspective. We focus particularly on preschoolers'…

We explored 12-month-olds' flexibility in accepting phonotactically illegal or ill-formed word forms in a modified associative-learning task. Sixty-four English-learning infants were presented with a training phase that either clarified the purpose of a sound--object association task or left the task ambiguous. Infants were then habituated to sets…

We examined whether 12-month-old infants privilege words over other linguistic stimuli in an associative learning task. Sixty-four infants were presented with sets of either word-object, communicative sound-object, or consonantal sound-object pairings until they habituated. They were then tested on a "switch" in the sound to determine whether they…

This study examined whether 12-month-olds will accept words that differ phonologically and phonetically from their native language as object labels in an associative learning task. Sixty infants were presented with sets of English word-object (N = 30), Japanese word-object (N = 15), or Czech word-object (N = 15) pairings until they habituated.…

An eye tracking methodology was used to evaluate 3- and 4-year-old children's sensitivity to speaker affect when resolving referential ambiguity. Children were presented with pictures of three objects on a screen (including two referents of the same kind, e.g., an intact doll and a broken doll, and one distracter item), paired with a prerecorded…

This study examined the influence of shape similarity and labels on 13-month-olds' inductive inferences. In 3 experiments, 123 infants were presented with novel target objects with or without a nonvisible property, followed by test objects that varied in shape similarity. When objects were not labeled, infants generalized the nonvisible property…

Examined influence of object labels and shape similarity on 16- to 21-month-olds' inferences. Found that infants generalized non-obvious property of unlabeled objects to test objects with highly similar shapes. For objects labeled with novel nouns, infants relied on shape similarity and shared labels to generalize properties. For objects labeled…

Two experiments examined infants' reliance on object shape versus color for word generalization to animate and inanimate objects. Infants were taught labels for either novel vehicles or novel animals using preferential-looking procedure or an interactive procedure. Results of both experiments indicated that infants limited their word…
