Data Analysis
The data analysis was carried out with IBM-SPSS version 24 statistical package. Since the variables did not follow a normal distribution, non-parametric tests were used.
Descriptive statistics and differences between groups in the reflexes variables were calculated and represented through box plots. The same was also calculated for MC and the crawling pattern. Secondly, Spearman correlation coefficients were obtained between every reflex score and the dimensions and the overall score of the Mabc-2 for both groups. Finally, Mann-Whitney U test was conducted to determine the differences between groups regarding reflex inhibition, MC and crawling pattern, as well as to assess potential gender differences. The effect size was calculated through r-statistic, using the formula r = Z/√N(N = number of measurements) and it was interpreted according to the next scale (Coolican, 2009) small (0–0.10), medium (0.10–0.30) or large (0.30–0.50).
