The law of similarity can account for grouping of stimuli that are similar in

The answer is orientation, shape, and pitch audition. The transition of two closely proximate stimuli through a neuron is often interspersed by delays. This is because the neuron has to repolarize before it can carry another impulse. This also leads to the belief that the human operator also processes information intermittently (in a discontinuous servo). Therefore, according to the law of grouping, stimuli that happen so closely together of simultaneously are often merged into a single decision response by the central nervous system based on the principles of Proximity, Similarity, Continuity, Closure, and Connectedness.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
