The size-distance scaling equation is S = K(R x D). The "S" in the equation stands for _____.
A) stimulus intensity
B) an object's perceived size
C) an object's physical size
D) an object's physical shape

Question

Quizplus · Accepted Answer

In the size-distance scaling equation, S stands for an object's perceived size, which is influenced by both its physical size (R) and its distance (D) from the observer. The equation shows that an object's perceived size (S) is proportional to the product of its physical size (R) and its distance (D) from the observer, with a constant of proportionality (K). Therefore, as an object's distance or physical size changes, its perceived size will also change according to this equation.
