DERMATOGLYPHICS, COORDINATION AND LITERACY IN PRIMARY SCHOOL: A CORRELATIONAL APPROACH
Keywords:
dermatoglyphics; motor coordination; literacy difficulties;Abstract
Objective: This study aimed to correlate dermatoglyphic characteristics with motor coordination of students with (Y/LD) and without literacy difficulties (N/LD). Methods: This is a cross-sectional and descriptive research, with comparative and correlational analysis. The sample consisted of 240 students (47.92% girls), aged between 6 and 11 years (7.51±0.76), dully enrolled in the primary 2nd and 3rd school years from Curitiba. Students were assessed by the following protocols: BMI; Curitiba test results, academic portfolio analysis, KTK test for motor coordination evaluation and dermatoglyphics. Results were presented using descriptive statistics. Results: Differences between groups were observed all 4 KTK tests (p< 0.01), as well as in the total motor quotient (z= 0.258, p< 0.01) and total score (z= 0.240, p< 0.01). No significant differences were noted between the dermatoglyphic variables. KTK results were strongly correlated with the Y/LD and N/LD groups (t (238) = 5.976, p< 0.01, d= 0.79). Conclusions: The study reinforced that there may be a close relationship between motor coordination and literacy difficulties.
