Spearman vs. Gardner: Two Theories of Intelligence
This paper compares and contrasts two major psychological theories of intelligence: Charles Spearman's general intelligence model (g) and Howard Gardner's theory of multiple intelligences. It traces Spearman's single-factor model through Raymond Cattell's refinements into fluid and crystallized intelligence, and examines how these ideas underpin standardized testing. The paper then outlines Gardner's eight-intelligence framework, its implications for learning styles, and its challenges to conventional IQ measurement. The paper concludes by arguing that Gardner's model is more culturally inclusive and better accounts for the role of environment in intellectual development.

What makes this paper effective
- The paper establishes a clear comparative framework early, naming both theorists in the introduction and signaling the structure of the argument before diving into detail.
- It builds logically from Spearman to Cattell to Gardner, showing how each theorist responds to or extends the one before, which gives the argument a satisfying developmental arc.
- The conclusion moves beyond summary by offering a normative judgment — that Gardner's model is superior because it is more culturally inclusive — grounding the claim in the critique of ethnocentrism.
Key academic technique demonstrated
This paper demonstrates the compare-and-contrast technique applied to competing scientific models. Rather than simply describing each theory in isolation, the writer uses Thurstone's 1938 critique as a pivot point, showing that Gardner's multiple-intelligences framework is a direct intellectual response to the limitations of Spearman's g. This move — situating a theory within a debate rather than presenting it in a vacuum — is a hallmark of strong undergraduate academic writing.
Structure breakdown
The paper opens with a definitional introduction, then devotes roughly equal space to Spearman's model (including Cattell's extension) and Gardner's model. A short applied section addresses standardized testing implications. The conclusion synthesizes the comparison by evaluating which model better accounts for cultural and environmental factors. The single source (Huffman, 2003) is cited consistently throughout.
Introduction
Psychologists define intelligence as a "general capacity to acquire knowledge" (Huffman 2003: 319). This knowledge allows a person to learn from experience and observation. Intelligence also allows humans to adapt to changes in their environment, or to adapt the environment itself through manipulation and the use of tools.
There is much debate, however, regarding the nature of intelligence and what cognitive functions comprise it. This paper compares and contrasts two prevailing theories of intelligence: one proposed by Charles Spearman and one proposed by Howard Gardner.
