The Information-Processing Theory focuses on the mental processes involved in acquiring, storing, and using information, emphasizing the role of attention, memory, and problem-solving abilities.

Robert Sternberg proposed the Triarchic Theory of Intelligence, which suggests that intelligence consists of three aspects: componential, experiential, and contextual.

Fluid Intelligence, which involves the ability to reason, solve problems, and adapt to new situations, tends to decline with age, while Crystallized Intelligence, which represents accumulated knowledge and skills, remains relatively stable.

The Multiple Intelligences Theory, proposed by Howard Gardner, suggests that there are eight distinct types of intelligence, including linguistic, logical-mathematical, musical, bodily-kinesthetic, spatial, interpersonal, intrapersonal, and naturalistic.

Charles Spearman introduced the concept of 'g' as a general factor of intelligence that underlies performance across various cognitive tasks.

The Wechsler Adult Intelligence Scale (WAIS) is a widely used intelligence test that measures various cognitive abilities, including verbal comprehension, perceptual reasoning, working memory, and processing speed.

The Cattell-Horn-Carroll (CHC) Theory of Intelligence proposes a hierarchical structure of cognitive abilities, with a general factor ('g') at the top and various specific cognitive abilities at lower levels.

Raven's Progressive Matrices is a nonverbal intelligence test that consists of a series of abstract patterns that participants must complete. It is widely used in cross-cultural research due to its minimal reliance on language.

Traditional intelligence tests have been criticized for focusing primarily on academic and linguistic abilities, potentially overlooking other important aspects of intelligence.

The Practical Intelligence Theory, proposed by Robert Sternberg, emphasizes the importance of practical problem-solving skills, everyday competence, and the ability to adapt to real-world situations.

The PASS Theory of Intelligence, developed by John B. Carroll, focuses on four basic cognitive processes: Planning, Attention, Simultaneous, and Successive Processing.

The Stanford-Binet Intelligence Scale is a widely used intelligence test that assesses cognitive abilities in individuals from early childhood to adulthood.

Critics argue that the concept of 'g' is too narrow and fails to capture the full range of cognitive abilities, potentially overlooking important aspects of intelligence.

The Triarchic Theory of Intelligence, proposed by Robert Sternberg, emphasizes the role of creativity, insight, and divergent thinking as important aspects of intelligence.

The PASS Theory of Intelligence, developed by John B. Carroll, focuses on four basic cognitive processes: Planning, Attention, Simultaneous, and Successive Processing.
