Purpose: The aim of this study was to describe changes in speech intelligibility and interrater and intrarater reliability of naive listeners' ratings of words produced by young children diagnosed with childhood apraxia of speech (CAS) over a period of motor-based intervention (dynamic temporal and tactile cueing [DTTC]). Method: A total of 120…

Efficient recognition of geometric shapes is an important aspect of proficiency in geometry. Building theoretically on the cultural-historical approach enriched by the physiology of activity, we investigate theoretical perception in geometry--the ability to recognize conceptual geometric aspects of visual figures. Aiming to understand the…

During a 6-week period, students in Grades 1-5 participated in 15 sensory activities that focused on processing and integration motor skills. The intervention group participated in 20 minutes of the "Minds in Motion" maze (10 minutes in the morning and afternoon) while the control group continued with normal school activities. Pre and…

Purpose: Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of…

For lifeguards, recognizing a swimmer in trouble is a key factor in the rescue process. Although reports show that lifeguards outperform non-lifeguards in their surveillance task, it is unclear to what extent this difference is reflected in gaze behaviour. In the current study, gaze behaviour of nine novice and seven experienced beach lifeguards…

Increasingly surveys are using interviewers to collect objective health measures, also known as biomeasures, to replace or supplement traditional self-reported health measures. However, the extent to which interviewers affect the (im)precision of biomeasurements is largely unknown. This article investigates interviewer effects on several…

Background: Perceptual motor development is crucial during early childhood and not properly addressing it in physical education (PE) can be detrimental. Aim: To determine the effect of a South African curriculum-aligned PE intervention on the visual-motor integration (VMI), visual perception (VP) and motor coordination (MC) of 6-year-old children.…

This dissertation examines how listeners' knowledge of interspeaker variability guides their generalization of perceptual learning in multi-talker listening. A series of perceptual learning experiments are conducted to evaluate whether listeners generalize what they have learned about a previous talker's production of sibilants and stop VOT to…

Music production and muscle movement are so interconnected that to begin the process of creating music, it is essential to consider the physicality behind the auditory perceptions. Playing-related injuries can arise from improper practice and failure to understand the physical movements underlying the music, and students and professional musicians…

Embodied cognition theories view sensorimotor activity as fundamental to learning, knowing, and reasoning. To investigate the role of physical movement in conceptual learning, we developed and explored an Embodied Learning Interactive Chemistry environment (ELI-Chem). The ELI-Chem learning environment includes a computer simulation, a device for…

An ability to perceive tactile and visual stimuli in a common spatial frame of reference is a crucial ingredient in forming a representation of one's own body and the interface between bodily and external space. In this study, the authors investigated young infants' abilities to perceive colocation between tactile and visual stimuli presented on…

Noradrenaline contributes to olfactory-guided behaviors but its role in olfactory learning during adulthood is poorly documented. We investigated its implication in olfactory associative and perceptual learning using local infusion of mixed a1-ß adrenergic receptor antagonist (labetalol) in the adult mouse olfactory bulb. We reported that…

South Africa consists of developed and developing contexts. This article reports on a study undertaken to determine the effect of a Perceptual--motor Intervention Programme in learning readiness of Grade R learners from deprived environments. Le Roux's Group Test for School Readiness was used as baseline assessments to establish the school…

Joint attention has been extensively studied in the developmental literature because of overwhelming evidence that the ability to socially coordinate visual attention to an object is essential to healthy developmental outcomes, including language learning. The goal of this study was to understand the complex system of sensory-motor behaviors that…

The spatial-temporal association indicates that time is represented spatially along a left-to-right line. It is unclear whether the spatial-temporal association is mainly related to a perceptual or a motor component. In addition, the spatial-temporal association is not consistently found using a time reproduction task. Our rationale for this…
