Objective:
To investigate the characteristics of visual motor integration in children with developmental dyslexia and ADHD, and to provide a reference for the diagnosis and treatment of these children.
Methods:
During July to November of 2020,students from grade 3 to grade 5 of 7 primary schools in Xinjiang were selected by using random cluster sampling method. A total of 56 dyslexia group (group DD), attention deficit hyperactivity disorder group (group ADHD), comorbidity group and normal control group were selected and compared the differences of their visual motor integration ability and related factors ability. Multiple linear regression analysis was used to explore the predictive effects of related factors on visual motor integration ability.
Results:
The scores of visual integration ability and visual perception in comorbidity group (95.05±14.01, 12.71±7.40) were lower than those in DD group (104.77±17.19,23.04±11.48), ADHD group (104.00±14.11,25.70±10.74) and normal control group (129.80±12.91, 44.05±16.56) ( F/Z =58.24,110.49, P <0.05). The visual working memory score of the comorbidity group ( 73.64 ±5.36) was lower than the normal control group (78.96±4.68) ( P <0.05),and there was no significant difference between the DD group (74.48±7.06) and the ADHD group (75.98±7.36) ( P >0.05). The results of multiple regression showed that visual perception, age, IQ and visual working memory were associated with visual and motor integration ability of dyslexia children with ADHD ( R 2=0.32,0.17,0.11, 0.04 , P <0.05).
Conclusion
Visual motor integration and visual perception among children with DD combined ADHD are more severely impaired than those with ADHD and DD alone. Visual perception, age, IQ and visual working memory could help predict the development of visual and motor integration ability in children with DD combined ADHD.

Objective:
To understand the relationship between emotional behavior and literacy of primary school students, and to provide evidence for improving the literacy of primary school students.
Methods:
A total of 3 710 students in grade 2 to 3 from three schools in Xinjiang were selected by random cluster sampling method, and were investigated with the Literacy Scale for Primary School Students and the Strengths and Difficulties Scale.
Results:
The average literacy of the second and third grade students( 947.85 ±335.93,1 519.45±509.88) were lower than the Shanghai literacy norm(1 414, 2 135), and the differences were statistically significant ( t =-62.15, -49.84, P <0.01). The abnormal detection rates of emotional behavior were peer communication problems (12.40%), prosocial behavior (12.02%), hyperactivity (11.59%), conduct problems (10.49%) and emotional problems (5.88%). Emotional symptoms ( r =-0.19), conduct problems ( r =-0.29), hyperactivity attention deficit ( r =-0.27), peer communication problems( r =-0.24) were negatively correlated with literacy scores( P <0.01). Regression analysis showed that peer interaction problems ( β =-24.45), hyperactivity problems ( β =-42.04) and conduct problems ( β =-50.73) had negative predictive effects on literacy ( R 2=0.12)( P <0.01).
Conclusion
Peer interaction problems, hyperactivity problems and conduct problems are moderately related to the literacy of primary school students.In the process of teaching, teachers should combine the psychological characteristics of students, adopt the teaching strategy of combining centralized literacy with written literacy, pay attention to the cultivation of literacy ability.
