Perceptual constancy refers to our ability to see things differently without having to reinterpret the object's properties.

Is differently referring to we see or things?

An adverb modifies or qualifies an adjective, verb, or other adverb.
The adverb differently is referring to the verb of the sentence you wrote.


In your words, 'we differently see things'. 'Things' means 'the situation' as opposed to actual objects. Another way of phrasing it would be 'see things from a different perspective'.

If the author meant 'see different things', he would say 'see different things'! :)

  • @Elendi I think the 'see' really means 'see', not a 'perspective' ...... so, I replace the pronoun with the noun. sorry, for my carelessness.

  • Ah, sorry... I thought the quote was referring to some kind of abstract object (as in programming).

It means that if we select a group of people, each one of them will see the same object/item in a different way. If you and I see a 8 oz glass with 4 oz of water, you may see it half-full and I half-empty.

Trivia: Apple's "think different" campaign should of read "think differently".

    ...or, "think 'different'."

    ...also, "should of" should have been "should have."
