Abstract

This study aimed to examine the effect of visual pre‐cueing presented at different time intervals in the response time of dyslexic and non‐dyslexic children. Fifteen dyslexic and 15 non‐dyslexic children performed a computerised four‐choice reaction time task across four conditions: no pre‐cue and a 43‐ms time interval (or duration) of a centralised dot appearing in the stimulus circle at 43, 86 or 129 ms prior to the stimulus. Each condition was repeated eight times, totaling 32 trials, and presented in a random order. Response correctness and response times were recorded for each trial, and z‐scores were obtained by standardising performance in the three pre‐cued conditions relative to the no pre‐cue condition. Dyslexic children took longer to respond in the task than non‐dyslexic children. Both dyslexic and non‐dyslexic children had faster response times in the pre‐cued conditions than in the conditions without the pre‐cue. These lower response times were inversely correlated with the length of the pre‐cueing interval. These results suggest that dyslexic children use visual pre‐cueing to improve decision‐making. The ability of dyslexic children to use pre‐cues may offer an interesting avenue for the exploration of interventions aimed at minimising behavioural and cognitive difficulties resulting from dyslexia.

Abstract

Considering that people with Parkinson's disease (PD) experience challenges in the control of both balance and eye movements, this study investigated the effects of saccadic eye movements on body sway in people with PD in two bases of support positions (side-by-side and tandem stances). Ten people with PD and 11 healthy individuals performed (a) fixation; (b) horizontal saccadic eye movements to the right and left; and (c) vertical saccadic eye movements up and down. The protocol for each postural task consisted of one block of six trials, making a total of 12 trials. Body sway and gaze parameters were measured during the trials. In both people with PD and healthy individuals, anterior–posterior body sway was significantly reduced in horizontal saccadic eye movements in contrast to fixation, regardless of the body position (side-by-side and tandem stances). Furthermore, vertical saccadic eye movements increased the area of sway in contrast to horizontal ones (and not to fixation) in people with PD. In addition, people with PD showed a higher number of fixations in all experimental conditions, without changes in the mean duration of fixations in both body positions. In conclusion, individuals with PD can improve body sway by coupling eye movements and postural sway when performing horizontal saccadic eye movements but not when performing vertical saccadic eye movements.

Abstract

Dyslexia, a disorder characterized by difficulties in learning to read and write, has aroused interest in many different areas of knowledge, including Information Design. Many recent studies have aimed at testing text formatting variables to design recommendations; however, specific guidelines are still scarce in literature. In this sense, this study conducted a narrative literature review on 19 articles addressing text formatting recomendations for people with dyslexia, including typography, layout, colors, media and images and compared to those stablished by the Dyslexia Style Guide (DSG) (2023). The results reveal that some DSG recommendations are well accepted among the scientific community while others, as well as some gaps regarding the topic, still require further investigation.
