Recommended: Why is validity and reliability important
This paper discusses the Bornstein PF model and traditional model of validity. It discusses how Bornstein maintains that it is important to use the PF model of validity. It discusses the tools used to group categories of mental activities and behaviors when responding to test. Furthermore, it discusses how Bornstein’s PF model could assess with validity in assessment of children with autism and difficulties with social functioning.
Validity is how well a test or measurement tool measures what it purports to measure. Traditionally validity is conceptualized into three categories content validity, construct validity, and criterion-related validity (Cohen, 2013). Content validity measures the validity based on an evaluation

The traditional approach correlational methods are used to quantify the association among test score and criterion. The PF model differs from traditional validity assessment not only with respect to how validity is conceptualized but also with respect to empirical emphasis. The PF model switches emphasis of validity theory and research from outcome to process and from correlation to experimentation. A process-driven approach and traditional validity assessment can enhance assessment procedures in the psychology field. This can enhance researchers’ knowledge of test score misuse by enlightening the fundamental intra-an interpersonal dynamics that guide to differential performance (and differential prediction) in different groups (Bornstein, …show more content…
This model conceptualizes validity to a level in which respondents are able to connect in expected psychological process during testing; once the processes are identified, experimental manipulations are introduced to alter these processes and determine whether the manipulations are introduced to alter theses processes and determine whether the manipulations affect test scores in meaningful ways. The PF framework reverses the usual procedure for dealing with extraneous variables that alter psychological test scores: Instead of viewing them as problematic, the PF model conceptualizes variables that are seen as confounds in traditional validity assessment (e.g., self-presentation effects) as opportunities for manipulation, exploration, and focused analysis windows on underlying process that would otherwise remain hidden. Psychological activities in which people engage when responding to psychological tests are determined by the nature of the instruments themselves by the types of questions asked and the task by the nature of the instruments themselves by the types of questions asked and the tasks and activities required of the respondent (Bornstein,
In the article N.C. Gov. Already Enforcing HB 2 with Trespassing Laws by Trudy Ring states that the governor of North Carolina says he will use trespassing laws to enforce the restroom provisions of House Bill 2, while officials of the state university says they won’t enforce the controversial law at all. "We 're using trespassing laws that we were using before House Bill 2, we 're using that now," he told reporters, according to a video. It also talks about a transgender case in Virginia regarding a boy who transgendered himself from female to male and was denied access to the school boys’ bathroom. This essay traces how governor of North Carolina, McCrory uses power, discrimination, and transphobia to deny transgender people the right to use the restroom based on their gender identity.
8. Validity - Validity is the degree to which a test measures what it is supposed to measure.
CHAPTER II METHODS Participants Forty members of a Research Methods in Psychology course at the University of Missouri – St. Louis (UMSL) served as participants in this examination. These participants were recruited within their respective laboratory periods. No money was awarded to the subjects for their participation.

Validity refers to ability of an instrument to measure the test scores appropriately, meaningfully, and usefully (Polit& Beck, 2010). The instrument has been developed to serve three major functions: (1) to represent a specific universe of content, (2) to represent measurement of specific psychological attributes, (3) to represent the establishing of a relationship with a particular criterion. There are three types of validity; each type represents a response to one of three functions
If a study is confounded, the researcher is not absolutely certain that changes in the dependent variable were caused by the manipulation of the independent variable, or some other uncontrolled variable. In a non-equivalent control group post-test only design, any differences observed between the two classes may be due to the non-equivalence of the groups and not to the injection of quizzes. No pre-test measures were given to establish equivalence.
Some students simply do not test well, others try their hardest and still cannot reach the impracticable standards set for them. The individuals who create these tests do not understand the pressures of being a student, or the struggle to answer thirty-five questions in a compressed time period. One test cannot accurately measure the intelligence of a student.
In conclusion, I am convinced of how the Skinner’s analysis of verbal behavior as a basis for assessment and intervention programs in children with autism provides a better technique resulting in better outcomes. The relationship between the tester and the kid is better and therefore the tester gets to know better the child and to efficiently work with the deficit on its language development.
In my first web paper I considered Attention Deficit Hyperactivity Disorder, and questioned whether its’ symptoms and underlying neurobiology should be considered a disorder, or rather simply a difference among humans’ nervous systems. In a further exploration of the idea of individuality within a diagnostically defined disorder, I have researched autism. By definition, autistic individuals present symptoms with varying degrees of severity. It is therefore considered a spectrum disorder, meaning that its’ “symptoms and characteristics can present themselves in a wide variety of combinations, from mild to severe (1).” A diagnosis of autism can result from any combination of its defined behaviors. In addition to this, there is a host of related disorders, in which some but not all symptoms of autism are present. These include Asperger Syndrome, Fragile X Syndrome, Rett Syndrome and Pervasive Developmental Disorder Not Otherwise Specified (PDDNOS) (4)(2). Because of its characteristic breadth, autism is a good example of the implications of being seen as an individual within a group possessing a defined disorder. Current professional opinion stresses the importance of accurately assessing differences in neurological deficits, even if they present similar autistic sympt...

Through behavioral assessment, “psychologists can count and record the frequency of particular behaviors” (Wood, Wood, & Boyd, 2014, p. 382). According to the textbook Mastering the World of Psychology, the MBTI’s limitation is that it has an “absence of rigorous, controlled validity studies of the inventory” (Wood et al., 2014, p. 385). Unlike the MBTI, the behavioral assessment takes a deeper, more in-depth look at how people respond to certain situations which I believe is a much more reliable way to understand an individual’s true personality rather than relying on their answers to questions on a
Standardized testing is a deeply flawed system. The American government continues to throw money at a program that has little or no hope of achieving the goals it set at its inception. The important message is that no test is valid for all purposes and “high stakes” decisions should not be made on the basis of a single test score. Test scores provide only a small picture of student achievement or potential (APA 2014).
Self-report personality inventories such as these allow for a comparison of various traits within an individual to other people’s qualities (Nevid, 2015, p. 435). Additionally, this form of testing is inexpensive to administer and score. Another benefit of these types of tests is the likelihood that one will be honest, due to the lack of face-to-face communication with an interviewer (Nevid, 2015, p. 436). Lastly, this form of testing also offers the possibility of boosting one’s confidence level, because of the positive wording that does not focus on the negative aspects of one’s personality (Caswell & Stromberg, 2015, para. 21). Nevertheless, negative factors remain, such as the results of these tests have the ability to change based on one’s mood, which may have been the reason for the variance in my testing results. According to an article by Vox media, fifty percent of testers had a changed result in as little as five weeks after the first testing experience (Caswell & Stromberg, 2015, para. 24). These self-reported tests depend on the truthfulness of the individual taking the test, thus they rely on the self-judgment of one’s opinion (Nevid, 2015, p. 435) Additionally, these tests which are bias, measure a single dimension of personality (Nevid, 2015, p.
These five developmental disorders are commonly known as Autism Spectrum Disorders. “The most common are Autism, Asperger's syndrome and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS) (www.learningdisabilitiesinfo.com).” Severe Autism, Rett Syndrome, and CDD are usually recognized before a child reaches the age of three. However, high-functioning Autism and Asperger’s are often times not discovered until a child enters school. High-functioning Autism and Asperger’s are frequently compared, considering children with these disorders express the same traits and characteristics. Conversely, the main difference between the two disorders is pragmatics, or language skills. A child with Asperger’s Syndrome is capable of communicating, but due to their social and developmental impairments, they cannot appropriately communicate with their peers. On the other hand, a child with Autism lacks language skills and requires spec...
