Cognitive effort is costly and this cost likely influences the activities in which children engage. Yet, little is known about how school-age children perceive cognitive effort. The subjective value of cognitive effort, that is, how valuable or costly effort is perceived, was investigated in seventy-three 7- to 12-year-olds using an effort…

Previous studies report that children use color words haphazardly before acquiring conventional, adult-like meanings. The most common explanation for this is that children do not abstract color as a domain of linguistic meaning until several months after they begin producing color words, resulting in a stage during which they produce but do not…

Adults find negative sentences difficult to process, but an informative context can facilitate processing substantially, suggesting that much of this difficulty may come from the pragmatics of negation. Are children sensitive to the pragmatics of negation as well? Although children perform poorly on many tests of negation comprehension, we argue…

Self-assessment and task selection are important self-regulated learning skills for secondary school students. More specifically, selecting new tasks based on self-assessments is very important for them, because teachers are not always present or able to select tasks for them individually. However, little is known about the processes underlying…

Purpose: The goals of this study were to (a) classify speech movements of patients with amyotrophic lateral sclerosis (ALS) in presymptomatic and symptomatic phases of bulbar function decline relying solely on kinematic features of lips and jaw and (b) identify the most important measures that detect the transition between early and late bulbar…

The Iowa Gambling Task (IGT) is widely used to study decision-making within healthy and psychiatric populations. However, the complexity of the IGT makes it difficult to attribute variation in performance to specific cognitive processes. Several cognitive models have been proposed for the IGT in an effort to address this problem, but currently no…

Children's ability to refer is underpinned by their developing cognitive skills. Using a production task (n = 57), we examined pre-articulatory visual fixations to contrast objects (e.g., to a large apple when the target was a small one) to investigate how visual scanning drives informativeness across development. Eye-movements reveal that…

During the first two years of life, infants concurrently refine native-language speech categories and word learning skills. However, in the Switch Task, 14-month-olds do not detect minimal contrasts in a novel object--word pairing (Stager & Werker, 1997). We investigate whether presenting infants with acoustically salient contrasts (liquids)…

To investigate phonological effects in visual word recognition, a visual lexical decision task was used in which the critical stimuli were two types of highly familiar Hebrew acronyms: 'phonological' acronyms that are conventionally pronounced as single words via letter-to-sound translation (?"? (d"?) = /da?/), and 'lexical' acronyms…

The purpose of the report is to explore some of the mechanisms involved in the writing process. In particular, we examine students' process data (keystroke log analysis) to uncover how students approach a knowledge-telling task using 2 different task types. In the first task, students were asked to list as many words as possible related to a…

Three-experiments examined the number of qualitatively different processing dimensions needed to account for inductive and deductive reasoning. In each study, participants were presented with arguments that varied in logical validity and consistency with background knowledge (believability), and evaluated them according to deductive criteria…

Journalism can serve as a generative disciplinary context for developing civic and information literacies needed to meaningfully participate in an increasingly networked and mediated public sphere. Using interviews with journalists, we developed a cognitive task analysis model, identifying an iterative sequence of production and domain-specific…

This research examined an important applied question: whether viewing ambient green (relative to red) on the wall of a workspace would facilitate creativity. A methodologically sound experiment revealed no influence of green on creativity. Care must be taken when interpreting a null result, but these data do not provide support for the presence of…

This dissertation examines the extent to which lexical aspect and grounding influence the acquisition of tense and aspect by ninety-four instructed adult learners of Italian in two academic settings in North America. The semantic notions of tense and aspect have been extensively investigated in the domain of second language acquisition. After more…

Cognitive load is a relevant phenomenon experienced by novice teachers moment-to-moment in complex classroom environments. Teachers learning to teach within the classroom daily encounter mental workload, but the latter has played little part in learning design for teachers, although other professions demanding complex performanes have made use of…
