• external cues in the environment.

• biologically induced hormones.

• accrued sleep debt.

Which of the following statements about sleep deprivation is correct?

• Sleep deprivation has no psychological effects.

• Sleep deprivation has lasting physiological effects.

• Sleep deprivation temporarily affects performance on cognitive tasks.
