Methods An EyeLink II was used to record the eye-movement parameters of 32 DD children and 37 non-dyslexic children as they performed the SCWT. The independent samples t-test and repeated measures were used to analyze behavioral and eye-movement parameters. Results Compared to the control group, Chinese DD children presented lower accuracy（F = 8.488）, slower response time（F = 25.306）, and larger interference effect（t = 2.29）; Chinese DD children also exhibited lower frequency of fixations（F = 6.069）, greater numbers of saccades（F = 7.914） and fixations（F = 5.272）, and shorter mean saccade distance（F = 4.03）. All behavioral and eye-movement parameters differed significantly among the three tasks in the SCWT. There was significant interaction between groups and tasks in accuracy（F = 5.844）, and marginally significant interaction in response time（F = 3.040）. Chinese DD children tended to have lower accuracy and longer response time than the control group in the ＇color-word naming＇ task. Conclusion Compared to non-dyslexic children, Chinese DD children are subject to a stronger interference effect. When performing the SCWT, Chinese DD children exhibit abnormal eye-movement patterns, namely shorter mean saccade distance, lower frequency of fixations, and more fixations and saccades. These abnormal eye movements may be relatively stable oculomotor patterns of DD children performing visual processing, and not influenced by impaired interference effect.展开更多

The researchers selected the research-based Drums Alive Kids Beat intervention because of its multidisciplinary methodology that in previous studies demonstrated positive effects on physiological, psychological, neurological, educational, rhythmical, and socio-emotional literacy. Facilitators used standardized Drums Alive approved lesson plans and equipment to conduct the intervention through a battery of music, movement and drumming-centered exercises and activities. The 30 participants were German students between 4.9 and 10.2 years of age, without any inclusion or exclusion characteristics, who were divided into three groups consisting of two intervention groups: IG Kindergarten (IG Kinder), IG Elementary<span style="font-family:;" "=""><span style="font-family:Verdana;"> (IG Elem) with varied physical, social, and emotional DD that affected gross and fine motor skills, movement, coordination, and behavioral control;and, a Control Group (CG) that had normal physical and motor skill development (</span><b><span style="font-family:Verdana;">Table 1</span></b><span style="font-family:Verdana;">). The results of the study suggested that the Drums Alive Kids Beats intervention provided statistically significant improvements in physical and motor skill performance in children with DD, namely, 24% improvement (IG Kinder), 14% (IG Elem) vice a minor 4% improvement (CG). Of note, during this study to measure physical capability pre- and post-intervention, the facilitators noticed significant improvements in behavior in both IG groups;therefore, they chose to conduct a collateral study to measure six behavioral domains which will be documented in a future publication to demonstrate the exclusive relationship between the Drums Alive Kids Beats intervention and improvement in behavior.</span></span>展开更多
