I sort of made my own schema of intelligence with two binary options for two vectors, creating four different categories of higher level reasoning:
Verbal vs Nonverbal
This does not refer to auditory vs visual stimulus but rather whether or not crystalized intelligence (even to a basic degree) is a requirement for succeeding at the task. Picture concepts is a verbal task with a visual stimulus because it relies on simple general knowledge to express categorical reasoning. VFI/VR is fluid reasoning with a crystalized knowledge threshold for expressing the former.
Reasoning vs Memory:
Verbal knowledge and visuospatial skills are vectors of memory (contextual verbal long-term retrieval and decontextual figural working memory, respectively) that correlate much more with verbal and nonverbal reasoning than contextual verbal short-term memory with a visual stimulus (picture span) and decontextual nonverbal short-term memory and working memory with an auditory stimulus (digit span and letter-number sequencing).
