Abstract: 
Research on the effects of sleep deprivation on covert
orienting of attention have produced evidence indicating
either a negative or a null impact of sleep loss. Moreover, it is
still unclear whether, following sleep deprivation, there is a
general impairment of orienting processes or a selective one.
Aim of the present study is highlighting the effects of sleep
deprivation on the three subcomponents of orienting of
attention: disengagement, moving and engagement (Posner
and Raichle, 1994). The ANT-R (Fan et al., 2009) was
administered following two sleep conditions: Baseline - a
regular night of uninterrupted sleep, and Deprivation - 24
hours of total sleep deprivation. We have found a significant
slowing down of the disengagement component, while
engagement and shift components were virtually unaffected
by sleep deprivation. Our data show that sleep deprivation
selectively affects the three subcomponents underlying covert
orienting of attention. Hence, they suggest that performance
deficits following sleep curtailment should no longer be
accounted for in terms of a general reduction of alertness or
global attentional deficits.
