Question: i think general intelligence is more plausible than modularity because 1. Evidence from factor analysis: Factor analysis is a statistical technique used to identify underlying factors that explain the correlations between different variables. When applied to cognitive ability tests, factor analysis consistently identifies a general factor or “g” that explains a large portion of the variance in performance across different domains. This suggests that there is a common underlying factor that influences cognitive abilities, supporting the idea of general intelligence. 2. Neuroscience evidence: Studies using neuroimaging techniques such as fMRI have shown that there is significant overlap in brain regions involved in different cognitive tasks, further supporting the idea of general intelligence. For example, studies have found that individuals who perform well on one cognitive task tend to perform well on other unrelated tasks as well, suggesting a common neural substrate. 3. Evolutionary perspective: The concept of general intelligence also makes sense from an evolutionary perspective. In order to survive and thrive in complex environments, it would be advantageous for individuals to possess a general cognitive ability rather than being limited to specific domains of cognition. make the paragraphs to be a complete sentence
