Theories of intelligence have evolved considerably over the past century, reflecting shifting perspectives on human cognition. Central to understanding these perspectives is the concept of general intelligence, or 'g', which encapsulates the overall mental ability that underpins specific cognitive skills (Spearman, 1927). The primary distinctions among the major theories—Spearman's two-factor model, Cattell-Horn's two-factor theory, Luria's information processing model, the CHC model, and Carroll's three-stratum theory—lie in their conceptualization of 'g' and its role in cognitive functioning. These differences influence how contemporary intelligence tests are developed and interpreted.

Spearman's two-factor theory posits a single dominant factor, 'g', that influences performance across all cognitive tasks. Spearman argued that 'g' is a stable, innate attribute, and specific abilities are subordinate to this general factor (Spearman, 1927). This theoretical foundation supports tests like the Stanford-Binet and early versions of the Wechsler scales, which aim to measure a core general intelligence. In contrast, Cattell-Horn's two-factor theory emphasizes a distinction between fluid intelligence (Gf) and crystallized intelligence (Gc). Gf relates to reasoning and problem-solving in novel situations, while Gc involves accumulated knowledge; these are influenced by different biological and experiential factors (Cattell, 1963; Horn & Cattell, 1966). This distinction informs modern tests that attempt to measure these separate components.

Luria's information processing approach shifts focus from a singular 'g' to the functioning of different brain processes involved in cognition, such as attention, perception, and memory (Luria, 1966). This perspective underscores cognitive processes rather than static intelligence factors, shaping assessments that evaluate processing speed, memory, and executive functioning. The CHC model integrates aspects of these theories, proposing a hierarchical structure with 'g' at the top and broad abilities underneath, which contain narrower skills (Cattell-Horn-Carroll, 1997). Carroll's three-stratum theory further refines this hierarchy, positioning 'g' at the apex, with second-order broad abilities and numerous narrow skills beneath. This comprehensive model underpins many modern intelligence tests and reflects an integration of earlier theories (Carroll, 1997).

Contemporary intelligence assessments have incorporated these theories variably. The Wechsler Intelligence Scale for Children (WISC), particularly in its fifth edition, relies on the CHC model, measuring both fluid and crystallized intelligence along with processing speed and working memory (Wechsler, 2014). The Kaufman Assessment Battery for Children (KABC-II) emphasizes information processing and fluid reasoning, indicative of Luria's influence (Kaufman & Kaufman, 2004). The Stanford-Binet Fifth Edition employs a hierarchical model resembling Carroll's theory to assess verbal and non-verbal reasoning skills (Roid, 2003). The Woodcock-Johnson Tests utilize a broad CHC-based structure to evaluate diverse cognitive abilities (Woodcock et al., 2014).

Multiple theoretical contributions influence current tests, leading to dual or hybrid models that combine elements of different theories. For instance, the WISC-V integrates the hierarchical CHC model and emphasizes multiple cognitive processes, aligning with a dual theoretical basis. Such integration aims to improve validity by capturing multiple facets of intelligence, aligning with the complex, multi-dimensional nature of cognition. Validity considerations suggest that tests grounded in multiple theories can offer a more accurate and comprehensive assessment of an individual's cognitive profile, accounting for diverse strengths and weaknesses.

Personally, I am most aligned with the CHC model, as it offers a flexible, comprehensive framework that encapsulates various intelligences and cognitive abilities. Its hierarchical structure reflects complexity while maintaining clear operational definitions, which is valuable for both research and practical assessment. In my professional pursuits, particularly in educational psychology, understanding and applying this model allows me to evaluate students' strengths and weaknesses accurately, facilitating tailored interventions. The CHC model's emphasis on broad and narrow abilities aligns with my goal of supporting diverse learning needs and promoting equitable cognitive assessments.

In conclusion, the development of intelligence theories has profoundly shaped contemporary assessment practices. Recognizing the differences in conceptualizing 'g' and integrating multiple perspectives enhances our understanding of cognitive abilities. As research progresses, hybrid models such as the CHC continue to dominate, offering nuanced insights and practical tools for practitioners dedicated to understanding human intelligence comprehensively.
