With a view to differentiating the individuals’ abilities, the intelligence test is introduced to investigate the individual differences across different countries, age groups and gender. However, the definition and measurement of intelligence are varied from time to time, and it raises the interest of psychologists to discuss the phenomenon. This essay will first describe the formation of the concept of intelligence. It will then depict the evolution of the intelligence test and its relation to the change of social environment. Finally, the intelligence test will be used as an example to explain the nature of psychology.
Several scientists attempted to coin the term "intelligence", but they have not yet reached a consensus on its precise …show more content…
The g-factor was constituted of several sets of intelligence skills and he found the factor was highly inter-correlated. For example, if the individual performed well on one intelligence test (e.g. mathematical task), they would also perform equally well on another task (e.g. spatial task). As a result, he claimed that the individuals’ performance on a specific task was not just simply related to the specific abilities but also correlated with ‘g’, which was the general intelligence that was required in order to succeed in all …show more content…
The Wechsler Intelligence Scale for Children (WISC) was employed in assessing the aged 5- to 16-year-old children in mainly verbal and performance intelligence. Besides, the Wechsler Adult Intelligence Scale (WAIS) was tested the 16- to 75-year-old individuals on the same intellectual skills as the children. The measurement of the intelligence was compared the test score to the expected scored at the same age. As a result, it could solve the problem that was arisen by Stern’s account (): the adults are expected to retain a constant mental age while the chronological age increased gradually, resulting in the decreased intelligence across the lifespan. Both tests that developed by Wechsler are still the most popular intelligence measurement in the contemporary society.
Psychology is one type of the social science. Similar to the evolution of intelligence measurement, psychology responded to the change of social environment. The concept of psychology changes across a period of time and condition, such as the emergence of the increased emphasis on education and the soldier selection of war. In other words, the changes were not solely due to the theoretical aim to differentiate the individuals but also the social problem at the time (Kamin,
