History:These are the unique experiences subjects have between the various measurements done in an experiment. Maturation--These are natural changes

Internal and External Validity Both internal and external validity are incredibly significant factors in a research study. If a research study is not valid there is no reason to rely on the information gathered. Internal validity is the extent that a researcher can trust the results of their research based on the relationship of the independent and dependent variable rather than external factors. Whereas, external validity refers to how much the results of a research study can be generalized. There

RELIABILITY AND VALIDITY RELIABILITY Reliability is the consistency or repeatability of a measure For example, if I use the measurement twice (e.g. take a test twice) would my scores be the same? Reliability focuses on the consistency of the measurement. If a measurement is reliable you should get the same results if you repeat it. With any measurement the score you get is the observed score. This score is a combination of the true score and error score. Researchers would of course like to eliminate

Based on Messick (1996), validity is defined as "an overall evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of interpretations and actions based on the test scores or other methods of measurement" (p. 221). Therefore, validity is the interpretations of test scores. In fact, validation is not directly related to test, however it's related to the inferences and interpretations regarding the test scores. It is said that

Hume explores the conception of personal identity

Leary, Wheeler and Jenkins (1986) conducted two studies to examine the relationship between an individual’s salient aspects of identity, and behavioral preferences. Both social and personal aspects of identities were considered for the purpose of these studies. According to Cheeks and Briggs (1982), the characteristics that form a person’s identity can be dichotomized into social and personal elements. Personal elements are those components of one’s self-definition that uniquely “belong” to an individual
