Compare and contrast the PF and the traditional models of validity The meaning and definition of validity has evolved from the review of Meehl’s classic (1995), although validity research emphasizes on assessing the relationship between predictor and criterion where in most cases the criterion becomes the self report. There are two models of validity which include the process-focused (PF) model and the traditional validity model. In the two models, they both test for the relationship between test score and criterion as well as the researchers will improve psychology’s assessment procedures. Assessment is a common change to the two models which is experienced by psychology in the diverse subfields. There is something which is measured in the …show more content…
In the process-focused model, the concept of validity is based in the degree to which respondents to participate in predictable psychological process in the time of assessment. While in traditional validity model the concept of validity is based on the correlational methods used in qualifying the relationship between test score and criterion. The process-focused model used experimental methods for the purpose coming up with variables that show the relationship between the test score and the criterion which will enable the researcher to draw better understanding. The traditional validity method does not use experimental methods. The process-focused model puts empirical emphasis which enables the researcher to manipulate variable hence helping the researcher draw conclusions, impacts of the process among others while traditional approach does not it only depends on the outcome. The traditional validity model are describes as static as it cannot predict outcomes of all criterion, the process-focused model can be used to predict any criterion since it can use the instruments required. The traditional approach tests for validity by observing only while the …show more content…
A human being has to pass through a number of brain disturbing situation where the human being will be stressed, made feel happy and made to cry where a doctor will record the proportion depending on how the brain will react. Where the brain has to react positively depending on the situation or what affects it. Hence after all this data on will be collected the validity of human brain on level of emotion will be determined. A number of questions will also be asked to the human being hard, simple and moderate it determines the ability of human brain. Each question should be given its proportion which will enable the researcher to assess the validity of human brain on its ability. Ask brainstorming question, general questions and course worker questions to determine and assess the intelligence of the human brain. Then the proportions of each question are recorded down and the researcher is able to determine the validity of the human brain in relation to intelligence.
3. Interpret the outcome
After all the data on the human brain has been collected, now the data can be interpreted. For example level of ability 80%, intelligence 89% and level of emotion stressed 80%,happy80%,cry 90%.What this means is that human brain is intelligent has ability and reacts positively to all types of emotions according to the action. The human brain cannot be 100% perfect it can
