Researchers Have Conducted Studies on a Variety of Vision-Like Processes

Researchers have conducted studies on a variety of vision-like processes that are unfamiliar to the general public. This research demonstrates that a mental image has roughly the same effect that an actual visual stimulus has, for example, in producing the masking effect. On the basis of this research, we can conclude that

A) demand characteristics probably cannot explain the results.
B) the propositional-coding explanation is likely to be correct.
C) visual imagery is stronger than auditory or motor imagery.
D) experimenter expectancy consistently influences the research on mental imagery.
