The ability to mentally re-experience past events improves significantly from childhood to young adulthood; however, the mechanisms underlying this ability remain poorly understood, partially because different tasks are used across the lifespan. This study was designed to address this gap by assessing the development of event-related potential…

Stimuli that capture the central tendency of presented exemplars are often preferred--a phenomenon also known as the classic beauty-in-averageness effect. However, recent studies have shown that this effect can reverse under certain conditions. We propose that a key variable for such ugliness-in-averageness effects is the category structure of the…

It is well established in studies of two-party conversation that conversational partners jointly establish brief labels for repeatedly mentioned entities. When speaking to a new partner who is unfamiliar with the labels, speakers use longer expressions to facilitate understanding. How this process of audience design scales up to multiparty…

Studies examining productive syntax have used varying elicitation methods and have tended to focus on either young children or adolescents/adults, so we lack an account of syntactic development throughout middle childhood. We describe here the results of an analysis of clause complexity in narratives produced by 354 speakers aged from four years…

Purpose: Our goal was to investigate whether preschool children with autism spectrum disorder (ASD) can begin to learn new word meanings by attending to the linguistic contexts in which they occur, even in the absence of visual or social context. We focused on verbs because of their importance for subsequent language development. Method:…

The school-based consultation literature includes a variety of empirically supported procedures for increasing teachers' implementation of classroom management strategies. However, teachers may respond differently to empirically supported consultation procedures. This study used a multiple baseline design across three elementary teachers to test…

Actions aim to produce effects in the environment. To accomplish this properly, we not only have to recruit the appropriate motor patterns, but also we must be able to monitor whether an intended effect has ultimately been realized. Here, we investigated the impact of such effect monitoring on performance in multitasking situations: Multitasking…

The article focuses on the omission of locative prepositions in child Russian. We report on two experiments: a production task and a comprehension task. Results from the elicited production task show that the majority of 2- and a minority of 3-year-olds (i) omit locative prepositions at nonnegligible rates, and (ii) do not conform to targetlike…

The reference of understood subjects (ecs) in complement control (John persuaded Peter[subscript i] ec[subscript i] to read the book) and temporal adjunct control (John[subscript i] tapped Peter while ec[subscript i] reading the book) has long been described as restricted to the object and subject of the main clause respectively. These…

This multiple probe across participants design evaluated the effectiveness of teaching early number sense skills (ENS) to young children (age 4) with autism spectrum disorder (ASD) using Number Talks with supports. Following participation in Number Talks with supports, young children with ASD learned the ENS skills of subitizing, one-to-one…

Previous research has found that different presentations of the same concept can result in different patterns of transfer to isomorphic instances of the same concept. Much of this work has framed these effects in terms of advantages and disadvantages of concreteness or abstractness. We note that mathematics is a richly structured field, with…

Student engagement in the second language classroom has been the focus of numerous researchers and teachers. Previous studies have shown that there are several dimensions of student engagement, but it is still unclear how they change (or not) over time and consequently how they affect actual task performance. This study investigated the task…

Atypical learning and memory in early life can promote atypical behaviors in later life. Less relational learning and inflexible retrieval in childhood may enhance restricted and repeated behaviors in patients with autism spectrum disorder. The purpose of this study was to elucidate the mechanisms of atypical memory in children with autism…

Within a language, there is considerable variation in the pronunciations of words owing to social factors like age, gender, nationality, and race. In the present study, we investigate whether toddlers link social and linguistic variation during word learning. In Experiment 1, 24- to 26-month-old toddlers were exposed to two talkers whose front…

This study compares the experts and the novices to investigate their information processing in dealing with the different degrees of recognition of shape-match stimulus by measuring the event-related potentials (ERPs). ERPs were recorded while 20 designers and 20 novices made shape-match judgments for table and chair sets. All of the tables were…
