Background: Mapping fraction symbols to magnitudes is easier for students to master than comparing fraction magnitudes. Fraction mapping assesses students' understanding of part-whole interpretations of fractions; fractions represent the parts of an object or set of objects. Fraction comparison assesses students' understanding of measurement…

The observations in this paper follow online focus group research involving mothers who play video games as a leisure pursuit. The study utilised an online focus group method within a custom online forum which split the forum into small virtual rooms, replicating small face-to-face focus groups in an online environment. The primary objective of…

Purpose: The goal of this study was to use speech resynthesis to investigate the effects of changes to individual acoustic features on speech-based gender perception of transmasculine voice samples following the onset of hormone replacement therapy (HRT) with exogenous testosterone. We hypothesized that mean fundamental frequency (f[subscript 0])…

Empirical evidence suggests a phonological loop deficit associated with Down syndrome. A trisomy 21 may be associated with a narrowing of visual attention to fewer than four objects at a time too. In a study with computer tachistoscopy, the hypothesis was confirmed in all 194 persons with trisomy 21. The subitising limit of persons with trisomy 21…

Children with autism spectrum disorder (ASD) who have limited spoken communication skills are commonly taught to mand by exchanging picture symbols. Competent manding via symbol exchange relies on conditional discrimination--that is, selecting the picture symbol that corresponds to the desired reinforcer. Picture Exchange Communication System…

The COVID-19 pandemic has forced governments and educational institutions around the world to look for viable alternatives to campus-based education. However, pedagogical methods such as Visual Thinking Strategies (VTS) might need to be adapted to low-interactivity distance learning environments, such as datacasting. This paper describes VTS+, a…

Usage-based Phonology proposes that language users' knowledge is stored in the form of exemplars reflecting experience of language usage. Exemplars encompass all visual and auditory information perceived during a language interaction, but few studies have examined the role that visual information plays. This dissertation addresses this question…

Evidence that physical activities are good for health and well-being is well established. However, the intrinsic motivation for many people is not high enough to generate active engagement. A simple way to encourage enrollment in ballet classes is to make course descriptions more attractive by combining textual impulses with before-and-after…

We constructed a computer game to support preschoolers' early word spelling without an adult's assistance. The study explored the relative influence of auditory and visual digital supports on children's performance. Participants were 96 preschoolers who were randomly assigned into one of three groups: no support, auditory only support, or auditory…

Agents are important for structuring memory in adulthood. However, it is unclear whether this "social memory bias" stems from a reliance on agents in verbal narratives, or whether it reflects more fundamental preverbal memory processes. By testing 9-month-old infants in a non-verbal eye-tracking paradigm, we were able to effectively…

Attention control abilities are relevant for learning success. Little is known about the development of audio-visual attention in early childhood. Four groups of children between the ages of 4 and 10 years and adults performed an audio-visual distraction paradigm (N = 106). Multilevel analyses revealed increased reaction times in a visual…

Students with the most significant cognitive disabilities often display deficits in mathematics. One method that has had limited research to determine the effectiveness with students with the most significant cognitive disabilities is a program called TouchMath. The purpose of this study was to investigate the use of the TouchMath strategy with…

With a brief half-second presentation, a medical expert can determine at above chance levels whether a medical scan she sees is abnormal based on a first impression arising from an initial global image process, termed "gist." The nature of gist processing is debated but this debate stems from results in medical experts who have years of…

This study examined the relationship between grade and the ability of text-picture integration in terms of task completion and the pattern of using textual and pictorial information. Children (N = 144) from secondary schools were recruited from grade 5 and grade 8. Analyzing the time spent with the multimedia unit prior to an incorrect response,…

The main purpose of this study was to systematically review and meta-analyse the single-case studies on the use of activity schedules with individuals with autism spectrum disorders. The other purposes were to describe the characteristics of activity schedule studies, assess the design standards of activity schedule studies, estimate the treatment…
