Here is an example: 100 infants are shown an object that appears to teleport, violating the rule that objects move in continuous paths. Another 100 similar infants are shown an object that behaves in a nearly identical manner to the object from group 1, except that this object does not teleport. If the former stimulus induces longer looking times than the latter, then, so the argument goes, infants expect that objects obey the continuity rule, and are surprised when they violate this rule. Some researchers have suggested, of some such experiments, that infants have innate knowledge of those rules the violation of which they can perceptually discriminate.
