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

<p>Data Set:</p> <p><strong>Abstract</strong></p> <p>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 (&plusmn; 0.92), mean height 156 (&plusmn; 5.27) and mean weight 46.19 (&plusmn; 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&deg; and 58-61% respectively).&nbsp; Results to the simple reaction time. ANOVA showed significant effects verbalization ([f = 68.77: p &lt;0.001]), sleep (f = 68.36: p &lt;0.001) and the interaction: sleep &times; Verbalization ([f = 28.7: p &lt;0.001]). For vigilance, following sleep deprivation, statistical analysis showed a significant decrease in alertness compared to the reference night (p &lt;0.001).</p> <p>&nbsp;</p> <p><strong>Keywords: </strong>Psychomotor Skills, Reaction time; Selective Sleep deprivation; Verbalization, Vigilance.</p>
