1.Validity refers to a test's ability to measure what it is supposed to measure.
2.Personal identity theory is the philosophical confrontation with the most ultimate questions of our own existence:who are we,and is there a life after death?In distinguishing those changes in a person that constitute survival from those changes in a person that constitute death,a criterion of personal identity through time is given.Such a criterion specifies,insofar as that is possible,the necessary and sufficient conditions for the survival of persons.Locke holds that personal identity is a matter of psychological continuity.He considered personal identity (or the self) to be founded on consciousness (viz. memory),and not on the substance of either the soul or the body.Locke holds that consciousness can be transferred from one soul to another and that personal identity goes with consciousness.
