Final answer:
Max Wertheimer concluded that apparent movement cannot be explained solely by sensations, as this perception involves the brain's higher-level organization that Gestalt psychology terms as being more than the sum of sensory stimuli.
Step-by-step explanation:
Max Wertheimer concluded that apparent movement cannot be explained by sensations alone because it involves a higher level of perceptual organization that cannot be reduced to the mere sum of its sensory parts. Wertheimer's research led to the development of Gestalt psychology, which emphasizes that the brain perceives objects in an organized and holistic way, rather than merely assembling sensory stimuli. He noticed that people perceive motion in a sequence of rapidly flickering static images, not because of any individual sensory experience but because of the brain's natural tendency to group and interpret stimuli.
These findings challenged the idea that perception is simply a function of sensory input and demonstrated that perception is a dynamic process that involves predictable ways of organizing sensory information. It aligns with other phenomena, such as the lack of sensation of Earth's movement as proposed by the heliocentric theory, indicating that our sensory experience does not directly correlate with physical movement.
