Effect of sleep deprivation and verbalization on cognitive and motor performance in male schoolchildren

Data Set:

Abstract

The aim of the present study was to examine the effect of verbalization on psycho-cognitive functions and psychomotor performance following selective sleep deprivation, among; 31 male students whose respective mean age 12.51 (± 0.92), mean height 156 (± 5.27) and mean weight 46.19 (± 4.24). After a predictive session and in random order, four experimental sessions were conducted: Two sessions (with and without verbalization) took place following a reference night (NR) and two sessions (with and without verbalization) after a sleep cycle disruption. Our experiment took place under the same temperature and humidity conditions (26-28° and 58-61% respectively).  Results to the simple reaction time. ANOVA showed significant effects verbalization ([f = 68.77: p <0.001]), sleep (f = 68.36: p <0.001) and the interaction: sleep × Verbalization ([f = 28.7: p <0.001]). For vigilance, following sleep deprivation, statistical analysis showed a significant decrease in alertness compared to the reference night (p <0.001).
