While a man provided directions to a construction worker,two experimenters rudely interrupted by passing between them carrying a door. The man's failure to notice that the construction worker was replaced by a different person during this interruption illustrates

A) REM rebound.
B) hypnagogic sensations.
C) activation-synthesis.
D) change blindness.

The scenario described represents a classic example of change blindness, where a person fails to notice a significant change in their environment due to a distraction or interruption. In this case, the passing of the experimenters with the door causes the man to overlook the replacement of the construction worker with a different person. REM rebound refers to an increase in the duration and intensity of REM sleep after a period of sleep deprivation. Hypnagogic sensations are the sensory experiences we have as we fall asleep, such as seeing flashes of light or feeling like we are falling. Activation-synthesis is a theory of dreaming that suggests that dreams arise from random neural activity in the brainstem, which is then synthesized into a narrative by higher brain regions. None of these concepts are directly related to the scenario described.
