Impairments in joint attention are considered core symptoms of autism spectrum disorder (ASD) and are crucial for early assessment and intervention. However, existing information about visual attention during joint attention and its relation to developmental functioning is limited. The current study investigated the visual attention differences…

Learning always happens from input that contains multiple structures and multiple sources of variability. Though infants possess learning mechanisms to locate structure in the world, lab-based experiments have rarely probed how infants contend with input that contains many different structures and cues. Two experiments explored infants' use of two…

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 =…

The literature on human and animal learning suggests that individuals attend to and act on cues differently based on the order in which they were learned. Recent studies have proposed that one specific type of learning outcome, the highlighting effect, can serve as a framework for understanding a number of early cognitive milestones. However,…

Although a fair amount is known about young children's production of negation, little is known about their comprehension. Here, we focus on arguably the most complex basic form, denial, and how young children understand denial, when it is expressed in response to a question with gesture, single word, or sentence. One hundred twenty-six children in…

In two experiments autobiographical memories from childhood were recalled to cue words naming common objects, locations, activities and emotions. Participants recalled their earliest specific memory associated with each word and dated their age at the time of the remembered event. A striking and specific finding emerged: age of earliest memory was…

An auditory sentence comprehension task investigated the extent to which the integration of contextual and structural cues was mediated by verbal memory span with 32 English-speaking six- to eight-year-old children. Spoken relative clause sentences were accompanied by visual context pictures which fully (depicting the actions described within the…

Two experiments investigated how young children and adults understand whether objects are "by" a landmark and remember their locations. Three- and 4-year-old children and adults were asked to judge whether several blocks were "by" a landmark. The blocks were arranged so that their absolute and relative distances from the landmark varied. Later,…

Two studies demonstrated that infants use referential cues to guide new word-object mapping as early as 19 to 20 months of age and that they understood that actions accompanying such labeling were not necessarily referential. These findings indicate that language learning is grounded in a relatively rich understanding of cues to reference, at…

Two studies examined whether preschoolers use whole-part juxtaposition to accurately interpret novel part terms. Results confirmed that children do use juxtaposition to guide learning of novel part terms and that such use was not due to memory effects nor to recognition of the grammatical frame accompanying juxtaposition. Children readily used…

Six match-to-sample picture/object selection experiments explored 3- to 5-year-olds' knowledge about superordinate words and acquisition of this knowledge. Findings indicated that number of standards (one versus two), types of standards (different versus same basic-level categories), and nature of representation (pictures versus objects)…

Children and adults were asked to place something "in front of" or "behind" a featured or nonfeatured object. Most subjects responded to the object's inherent features. A significant number of adults used the observer orientation cue. Children had more difficulty with the nonfeatured object but also used the observer…

Clarifies features of Smith et al.'s attentional learning account of object naming, arguing that Booth and Waxman's findings address tenets not in the attentional learning account while not addressing one of the central tenets of the attentional learning account. Suggests that the debate about the nature of children's language and cognition would…

Responds to Smith et al.'s work on relations between perceptual, conceptual, and linguistic knowledge in early word learning and discusses treatment of evidence. Asserts that Smith et al.'s commentary fails to engage data presented and their implications. Asserts that learners seamlessly integrate perceptual, linguistic, and conceptual information…

Examined word retrieval in 14- to 24-month-olds. Found that children with limited productive vocabularies were less likely to produce labels of hidden objects than children with larger vocabularies, even though all could name them and did well when asked to find them. Pictorial cues facilitated word retrieval. Naming errors peaked among children…
