A study (Pilcher & Huffcutt, 1996) was conducted to examine the impact of various types of sleep deprivation on mood and performance. The results of this study revealed that

B) though their moods generally suffered, sleep-deprived participants had cognitive and physical performances roughly equivalent to non-deprived participants
C) both partial and total sleep-deprived participants experienced strong negative effects on mood and performance
D) in contrast to mood and physical performance, cognitive performance on tasks was unaffected in sleep-deprived participants
