External visualization (i.e., physically embodied visualization) is central to the teaching and learning of mathematics. As external visualization is an important part of mathematics at all levels of education, it is diverse, and research on external visualization has become a wide and complex field. The aim of this scoping review is to…

Studies have indicated that pictures in test items can impact item-solving performance, information processing (e.g., time on task) and metacognition as well as test-taking affect and motivation. The present review aims to better organize the existing and somewhat scattered research on multimedia effects in testing and problem solving while…

The spatial split-attention principle suggests that presenting related words and pictures spatially close to one another will improve learning compared with a spatially distant design, and two meta-analyses have shown support for the principle. However, it is not clear why the principle occurs. It has been theorized that integrated graphic designs…

Purpose: This systematic review focuses on the effect of bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) on language function in Parkinson's disease (PD). It fills an important gap in recent reviews by considering other language tasks in addition to verbal fluency. Method: We critically and systematically reviewed the…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…

Clinical Question: Do children with complex communication needs show greater improvement in requesting behaviors with the Picture Exchange Communication System® (PECS®) versus a speech-generating device (SGD)? Method: Systematic Review. Sources: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information…

In the present study, we aimed to make an evaluation, conduct comprehensive descriptive analyses, and calculate the effect sizes of studies which compare AAC applications designed according to single-subject research designs and conducted for individuals with ASD. Within the scope of this aim, 21 studies meeting the inclusion criteria were…

Although convergent research demonstrates that well-designed graphics can facilitate readers' understanding of text, there are select situations where graphics have been shown to have no effect on learners' overall text comprehension. Therefore, the current meta-analytic study examined 39 experimental studies published between 1985 and 2018…

Visual supports are recommended in autism spectrum disorder clinical guidelines. They can reduce anxiety, increase predictability, support communication and improve participation. They are implemented regularly in schools, but evidence about home visual supports is limited. This article reports results of a scoping literature review, alongside…

The Dimensional Change Card Sort (DCCS) task is a widely used measure of preschoolers' executive function. We combined data for 3,290 3-year-olds from 37 unique studies reporting 130 experimental conditions. Using raw pass/fail counts, we computed the pass rates and chi-squared value for each against chance (50/50) performance. We grouped data…

Mathematics word-problems continue to be an insurmountable challenge for many middle school students. Educators have used pictorial and schematic illustrations within the classroom to help students visualize these problems. However, the data shows that pictorial representations can be more harmful than helpful in that they only display objects or…

This paper provides an overview of the literature investigating the functional relationship between the use of the Picture Exchange Communication System (PECS) and maladaptive behavior (i.e., aggression, tantrums) in individuals with autism spectrum disorders (ASD). Digital searches were conducted to identify single subject design studies…

A literature review was conducted to describe important concepts involved in functional analysis of verbal behavior as well as to evaluate empirical research findings on acquisition of picture exchange-based vs. signed mands to suggest instructional implications for teachers and therapists to teach functional communication skills to children with…

The population of students who are deaf/hard of hearing (D/HH) that have additional disabilities remains at over 40 per cent. One population of particular concern is the group of D/HH students with a comorbid diagnosis of autism spectrum disorders (ASD). The prevalence of ASD in the D/HH population is 1 in 59 (Szymanski et al., 2012. "Deaf…

Over the past decade, computer games and other interactive technologies have shown great potential when used in innovative ways to enhance learning. It is now known that learning is associated not only with cognitive ability but also with affect. The incorporation of affective embodied pedagogical agents (EPAs) in computer programs for learning…
