This article presents a review of the Comprehensive Test of Nonverbal Intelligence-Second Edition (CTONI-2), a nonverbal intelligence test created to assess reasoning and problem solving of children and adults. The goal of the CTONI-2 is to minimize the influence of language ability on intelligence test scores. Oral or pantomime instructions can…

Seventy-nine 3- and 4-year-old children were tested on gaze-reporting ability and Wellman and Liu's (2004) continuous measure of theory of mind (ToM). Children were better able to report where someone was looking when eye and head direction were provided as a cue compared with when only eye direction cues were provided. With the exception of…

Learning to perform self-care skills can pose a major challenge for children with Autism Spectrum Disorder (ASD) as well as the parents and caregivers who support them. The computerized device described in this paper has been used by children with ASD and their carers to autonomously assist with self-care activities. The device uses computer…

Background: Fragile X syndrome (FXS) is an early diagnosed monogenic disorder, associated with a striking pattern of cognitive/attentional difficulties and a high risk of poor behavioural outcomes. FXS therefore represents an ideal model disorder to study prospectively the impact of early attention deficits on behaviour. Methods: Thirty-seven boys…

Research has shown that variability may be an operant dimension of behavior. One method of reinforcing response variability is to use a lag schedule of reinforcement (Page & Neuringer, 1985). Several studies have shown that a Lag 1 schedule is effective in increasing variable responding with human participants (e.g., Esch, Esch, & Love, 2009; Lee,…

This research addresses the challenges of assessing receptive language abilities in minimally verbal children with autism spectrum disorder by comparing several adapted measurement tools: a standardized direct assessment of receptive vocabulary (i.e. Peabody Picture Vocabulary Test-4); caregiver report measures including scores on the Vineland-II…

Directed actions can play a causal role in cognition, shaping thought processes. What drives this cross-talk between action and thought? I investigated the hypothesis that representations in spatial working memory mediate interactions between directed actions and problem solving. Participants attempted to solve an insight problem while…

Approximately 5% of older adults have a dementia diagnosis, and language deterioration is commonly associated with this disorder (Kempler, 2005). Several instruments have been developed to diagnose dementia and assess language capabilities of elderly adults. However, none of these instruments take a functional approach to language assessment as…

The presentation of a hand grasp facilitates the recognition of subsequent objects when the grasp is coherent with the object to be identified. This outcome is usually explained as the integration of two different processes: descriptive visual processes in ventral visual areas and processes in charge of the computations of action metrics in dorsal…

Purpose: Vocal, gestural, and graphic communication modes were implemented concurrently with a toddler with Angelman syndrome to identify the most efficiently learned communication mode to emphasize in an initial augmentative communication system. Method: Symbols representing preferred objects were introduced in vocal, gestural, and graphic…

Researchers and educators recognize that performance assessments and naturalistic observations are well suited for assessing young children's thinking abilities and understanding. The need to establish explicit evaluation criteria to guide assessment decisions has led to the widespread use of rubrics. Rubrics tend to channel assessors to look for…

This study investigates caption-reading behavior by foreign language (L2) learners and, through eye-tracking methodology, explores the extent to which the relationship between the native and target language affects that behavior. Second-year (4th semester) English-speaking learners of Arabic, Chinese, Russian, and Spanish watched 2 videos…

A problematic issue for forensic interviewers is that young children provide limited information in response to open-ended recall questions. Although quantity of information is greater if children are asked more focused prompts and closed question types such as yes/no or forced choice questions, the quality of their responses is potentially…

An increasing number of studies has investigated the latent factor structure of executive functions. Some studies found a three-factor structure of inhibition, shifting, and updating, but others could not replicate this finding. We assumed that the task choices and scoring methods might be responsible for these contradictory findings. Therefore,…

The project was conducted to make an online tutoring program for math word problem solving accessible to students with visual impairments (VI). An online survey of teachers of students with VI (TVIs) guided the decision to provide the math content in the form of an iPad app, accompanied by print and braille materials. The app includes audio…
