We sought to evaluate a set of procedures based on Relational Frame Theory in teaching children with disabilities to reason analogically using relations between the contextual cues "same," "opposite," and "different." Two children were first taught to respond to the relational cues using common pictures and were…

Humans appear to intuitively grasp definitions foundational to formal geometry, like definitions that describe points as infinitely small and lines as infinitely long. Nevertheless, previous studies exploring human's intuitive natural geometry have consistently focused on geometric principles in planar Euclidean contexts and thus may not…

This longitudinal study examined how receptive and expressive vocabulary assessments capture vocabulary development in children with Autism Spectrum Disorder (ASD) and typically developing (TD) children. Using mixed regression modelling, we explored when children with ASD significantly different from TD children. We also examined the variability…

This study traced different types of distractor effects in the picture-word interference (PWI) task across repeated naming. Starting point was a PWI study by Kurtz et al. (2018). It reported that naming a picture (e.g., of a duck) was slowed down by a distractor word phonologically related to an alternative picture name from a different taxonomic…

Background: Although most prevalent in childhood, the acquisition of new words in oral vocabulary takes place right across the lifespan. Of the many factors that influence oral vocabulary learning, one extrinsic factor is the listening environment. The current study aimed to examine whether the presence of noise impacts oral vocabulary learning in…

Introduction: Analysis of the relationship between test scores and other variables provides an important source of evidence for validity. As a new instrument, evidence of validity of Pictorial Vocational Interest Inventory (PVII) is needed to support its psychometric properties. The purpose of this study is to obtain evidence of the validity of…

Unlike children's early ability to navigate by continuous boundaries, their ability to extract geometric information from an array of objects emerges gradually over childhood. To investigate children's developing representation of object arrays for navigation and its relation to their mental representation of the global spatial layout,…

This study investigates elementary school teachers' perceptions of the appropriate proportions of cartoons for instructional purposes, with a focus on the Thai educational context. The research aims to shed light on teachers' preferences for cartoon proportions across different grade levels, contributing valuable insights into the effective use of…

This case study inspected mathematical learning opportunities that employed the results from the participating preservice teachers' (n=75) original visual arts creation process. Data obtained during this study provided empirical evidence for the educational viability of employing original Mondrian-style rectangle sets as a context for generating…

The purpose of this study was to assess whether variations in visual stimulus presentation during tact training would affect efficacy, efficiency, and the emergence of listener responses. Participants included two preschool-aged children diagnosed with autism. We implemented two teaching conditions using an adapted alternating treatment design…

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…

In a series of sentence-picture verification studies we contrasted, for example, "… choose the balloon with "… inflate the balloon" and "… the inflated balloon" to examine the degree to which different representational components of event representation (specifically, the different object states entailed by the inflating…

Purpose: Little is known about the relationship between discourse comprehension and production in traumatic brain injury (TBI), especially for spoken language. This study examined to what extent narrative discourse comprehension accounts for narrative discourse production outcomes (story grammar, story completeness). A secondary aim was to…

In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and…

In recognition, context effects often manifest as higher hit and false-alarm rates to probes tested in an old context compared with probes tested in a new context; sometimes, this concordant effect is accompanied by a discrimination advantage. According to the cue-overload account of context effects (Rutherford, 2004), context acts like any other…
