Briefly compare and discuss at least two theories of intelligence and the contemporary assessment measures related to those theories.
1). Thurstone’s Primary Mental Abilities theory purposes that, researches can pinpoint specific group factors and define those factors specifically. Thurstone listed the follow factors of intelligence. 1. Verbal Comprehension: This factor can include reading and verbal equivalences. 2. Word Fluency: Measures the speed a person can name words in a given category, for example, tools that start with the letter R. 3. Numbers: The speed and accuracy of math problems. 4. Space: visualization and recognition of 3 dimensional shapes and how they would appear if flipped or rotated. 5. Associative Memory: A person’s skill in wrote memory. 6. Perceptual Speed: Recognizing similarities or difference in visual facts. 7. Inductive Reasoning: The finding of patterns in number series are a good example of this measure. Thurstone’s theory of intelligence is still in use today to investigate adult intelligence as we age.
2. Cattell-Horn-Carroll (CHC) Theory is a broad measure of factors split into three main parts, stratum I, II, and III. This theory purposes up to 70 different abilities that can be measured into intelligence testing. Some of these are broad, but some of these factors are quite narrow in scope.
The main difference between theses is that, Thurstone’s theory is broken up into more general categories, were as, CHC is comprised of multiple broad and narrow categories, as they comprise a more comprehensive list. (Gregory, 2014).
