Question: The first known psychometric instrument developed in nigeria was developed in what year?
The history of psychometrics in Nigeria is a fascinating topic that deserves more attention. Psychometrics is the science of measuring psychological attributes such as intelligence, personality, and attitudes. One of the earliest attempts to develop a psychometric instrument in Nigeria was made by Akinola Aguda in 1954. Aguda was a Nigerian lawyer and judge who had a keen interest in psychology. He devised a test of mental ability for Nigerian secondary school students, which he called the Aguda Test. The test consisted of 100 multiple-choice items that covered verbal, numerical, and spatial reasoning. Aguda administered the test to over 2,000 students from different regions and ethnic groups in Nigeria. He found that the test had high reliability and validity, and that it could discriminate between students of different academic abilities. He also found that there were no significant differences in performance between students from different regions or ethnic groups, suggesting that the test was culturally fair. Aguda published his findings in a book titled The Aguda Test of Mental Ability for Nigerian Secondary School Students, which was the first book on psychometrics written by a Nigerian author. Aguda's test was a pioneering contribution to the field of psychometrics in Nigeria and Africa. It showed that it was possible to develop a psychometric instrument that was suitable for the Nigerian context and that could measure the cognitive abilities of Nigerian students. Aguda's test also inspired other Nigerian psychologists to develop their own psychometric instruments, such as the Nigerian General Aptitude Test (NGAT) and the Culture Fair Intelligence Test (CFIT). These tests have been widely used for educational and occupational purposes in Nigeria and other African countries. Psychometrics in Nigeria has continued to grow and evolve over the years, with new instruments being developed and validated for various psychological constructs. The field has also faced some challenges, such as the lack of standardized norms, the scarcity of resources, and the influence of cultural factors. However, psychometrics in Nigeria has also shown resilience and creativity, as Nigerian psychologists have adapted existing instruments or created new ones to suit their needs and contexts. Psychometrics in Nigeria is a rich and diverse field that reflects the history and culture of the Nigerian people.
