Take a practice IQ test (although not a valid or reliable measure of your intelligence) and read the sample report generated. Notice the adjusted score and where your score falls on the bell curve, the range and percentile score as well as the descriptor. Be sure to convert your scores to the Catell and Stanford Binet scales and notice if there are any differences. Use the link to the IQ Testing Lab provided: www.intelligencetest.com/index.htm
Prepare a brief overview (1 page in length; you may put this in a table or paragraph form) of your results, the conversions, and any differences that occur. Then respond in a 3-5 page, APA formatted paper to the following:
- In your opinion, was this a fair measurement of your intelligence? Why or why not? Support your answer with what you have learned about IQ tests.
- Discuss possible limitations with interpretation of your results within the context of what you have learned about psychometric test properties. How would you explain the reliability and validity of this test to someone who has not taken this course?
- Explain whether you felt this test minimized cultural bias, based on what you have learned so far.
- What ethical limitations might prevent the use of this type of test in major decision-making (e.g., entrance to college, identifying disabilities, etc.)?
- Analyze the possible influence of the format of the test (e.g., computer versus manipulatives or paper, timed versus untimed, standardization, multiple choice, etc.) on your results, based on what you have learned about various testing instruments so far.
Recall our consultant, Keith, from Module 1. Keith has been asked to conduct a psychological evaluation on an adolescent female. Her teachers and parents are concerned that her grades have been dropping and she has been acting out.
Keith is short on time and needs to complete his assessment quickly. He likes using the MMPI-A and decides to send a protocol home for the girl to complete. Once she returns it, he’ll score it and determine if the girl’s personality is somehow influencing her grades and behavior changes.
Refer to the Ethical Principles of Psychologists and Code of Conduct Standard 9 on Assessment (APA, 2010).
- What ethical concerns does Keith need to consider?
- As Keith’s colleague, what advice can you give him based on what you have learned about psychological assessment?
