Background: There are few well validated brief measures that can be used to assess the general progress of young children with autism spectrum disorders (ASD) over time. In the present study, the Autism Treatment Evaluation Checklist (ATEC) was used as part of a comprehensive assessment battery to monitor the progress of 22 school-aged children…

This longitudinal study focused on the effects of two different principles of intervention in children at risk of developing dyslexia from 5 to 8 years old. The children were selected on the basis of a background questionnaire given to parents and preschool teachers, with cognitive and functional magnetic resonance imaging results substantiating…

New studies on how language learning occurs are beginning to chip away at some long-held notions about second-language acquisition and point to potential learning benefits for students who speak more than one language. New National Science Foundation-funded collaborations among educators, cognitive scientists, neuroscientists, psychologists, and…

This article presents an exploratory study aimed at the identification of students' levels of understanding in spherical geometry as van Hiele did for Euclidean geometry. To do this, we developed and implemented a spherical geometry course for student mathematics teachers. Six structured, "task-based interviews" were held with eight student…

The authors aimed to incorporate learning into the cognitive assessment framework that exists for static assessment data. In order to accomplish this, they derive a common likelihood function for dynamic models and introduce Parameter Driven Process for Change + Cognitive Diagnosis Model (PDPC + CDM), a dynamic model which tracks learning…

A case study was used to analyse the relationships between participation in an online discussion forum and the cognitive quality of the contributions made. Participation was calculated using two dimensions: presence (who accesses the environment, how often and for how long) and connectivity (who interacts with whom and the degree of intensity of…

To pursue goal directed behavior, the cognitive system must be shielded against interference from irrelevant information. Aside from the online adjustment of cognitive control widely discussed in the literature, an additional mechanism of preventive goal shielding is suggested that circumvents irrelevant information from being processed in the…

According to dual-process accounts of thinking, belief-based responses on reasoning tasks are generated as default but can be intervened upon in favor of logical responding, given sufficient time, effort, or cognitive resource. In this article, we present the results of 5 experiments in which participants were instructed to evaluate the…

In this study, qualitative evidence is collected--through classroom observations and teacher and student interviews--to study the effect of metacognition and the interaction between students' observable cognitive behaviour and the instructional task. This qualitative data is analysed to identify what factors support and improve students'…

Prior research suggests that exposure to conflict can negatively impact the development of executive functioning, which in turn can affect academic performance. Recognizing the need to better understand the potentially widespread executive function deficiencies among Palestinian students and to help develop educational resources targeted to youth…

Introductory biology courses are widely criticized for overemphasizing details and rote memorization of facts. Data to support such claims, however, are surprisingly scarce. We sought to determine whether this claim was evidence-based. To do so we quantified the cognitive level of learning targeted by faculty in introductory-level biology courses.…

We report a series of investigations into the effects of common names, physical identity, and physical similarity on visual detection time. The effect of these factors on the capacity of the system processing the signals was also examined. We used a redundant targets design with separate testing of the target-distractor (single target),…

Backward inhibition (BI) refers to a reaction time cost incurred when returning to a recently abandoned task compared to returning to a task not recently performed. The effect has been proposed to reflect an inhibitory mechanism that aids transition from one task to another. The question arises as to precisely what aspects of a task may be…

In 1993 Carey and Smith conjectured that the most promising way to boost students' understanding of the nature of science is a "theory-building approach to teaching about inquiry." The research reported here tested this conjecture by comparing results from two Grade 4 classrooms that differed in their emphasis on and technological…

Background: The majority of available psychometric tests originates from the Western World and was designed to suit the culture, language, and socio-economic status of the respective populations. Few tests have been validated in the developing world despite the growing interest in examining effects of biological and environmental factors on…
