Visual Implicit Pre-Cueing Improves Response Time in Decision-Making in Dyslexic Children.

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.

Previous research has demonstrated that biological motion (BM) cues can induce a reflexive attentional orienting effect, a phenomenon referred to as social attention. However, it remains undetermined whether BM cues can further affect higher-order cognitive processes, such as visual working memory (WM). By combining a modified central pre-cueing paradigm with a traditional WM change detection task, the current study investigated whether the walking direction of BM, as a non-predictive central cue, could modulate the encoding process of WM.

Article Synopsis
- This study explores how spatial attention affects signal detection in patients with glaucoma, particularly in areas of the visual field that are damaged.
- It compares the performance of glaucoma patients with age-matched controls when identifying letters in crowded versus isolated conditions, finding that pre-cueing the target's location improves detection in patients but not in controls.
- The results suggest that glaucoma patients experience more difficulty with crowding and that directing attention can help enhance their perception in challenged visual areas.
Different attentional focus sizes modulate the size-eccentricity effect.

Department of Psychology, Suzhou University of Science and Technology, Suzhou, China.
The size-eccentricity effect is a perceptual distortion phenomenon in which a peripherally located object is perceived to be smaller than a centrally located object. Although the increase in apparent object size caused by attention has been documented, little is known about the effect of different sizes of attentional focus on object appearance. The present study investigated how different sizes of attentional focus affect the size-eccentricity effect using a spatial pre-cueing paradigm.
