Final answer:
The current definition of intellectual ability is based on various theories and perspectives, including the Cattell-Horn-Carroll theory and multiple intelligences theory. Intelligence is hierarchically organized with general and specific abilities, and can be manifested in different forms. The concept of intelligence has evolved over time to not only include cognitive abilities, but also practical skills and success-promoting behaviors.
Step-by-step explanation:
The current definition of intellectual ability is based on various theories and perspectives. One theory is the Cattell-Horn-Carroll (CHC) theory of cognitive abilities, which suggests that intelligence is hierarchically organized with general abilities at the top and specific abilities at the bottom. Another perspective is the multiple intelligences theory proposed by Howard Gardner, which suggests that intelligence can be manifested in different forms such as linguistic, logical-mathematical, musical, spatial, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic intelligences. Additionally, the concept of intelligence has evolved over time, with early psychologists like Charles Spearman emphasizing a general factor of intelligence and more recent thinkers considering practical abilities and skills that promote success in life.
