A neuroscientist hypothesizes that the brain's perception of time depends on the rate of incoming information processed, rather than on a dedicated internal clock, with denser information producing perceived expansion of time.

Which finding, if true, would most strongly support the neuroscientist's hypothesis?

  • A

    The brain has many specialized regions.

  • B

    Many people overestimate short durations.

  • C

    Time perception varies across individuals.

  • D

    Participants who viewed video clips packed with novel visual information judged the clips as significantly longer than equally timed clips with little new information, even when actual durations were identical.

Explanation

A directly tests the hypothesis: equal real durations but different information densities produce different perceived durations. B, C, and D are general or tangential.
