To be a bit more specific, Howard Gardner maintained there were
at least 8 distinct forms of intelligence:
1. Linguistic intelligence: i.e., poetry
2. Logical-mathematical intelligence: i.e., what Jean Piaget looked for
3. Musical intelligence: sensibility to sound patterns
4. Spatial intelligence: i.e., visual artists
5. Bodily-kinesthetic intelligence: i.e., surgeons, dancers, martial artists
6. Interpersonal intelligence: social intelligence and sensitivity to the thinking of others; i.e., psychologists and salesmen
7. Intrapersonal intelligence: sensitivity to what you're thinking and feeling
8. Naturalist intelligence: i.e., herbalists and trackers
So-called “cognitive development” and "cognitive intelligence" usually refers to the line of logical-mathematical intelligence, which Jean Piaget studied.
Gardner also made it clear that by no means did he maintain these 8 were the
only forms of intelligence out there, they're just the ones that stood out. Philosopher Ken Wilber, for example, maintains there are roughly 24 distinct developmental lines (or "intelligences"), including the 8 used by Gardner (as well as the psychosexual "line" studied by Freud, the psychosocial "line" studied by Erikson, the self-needs "line" studied by Maslow, the moral reasoning "line" studied by Kohlberg, the self-identity "line" studied by Gebser, the values-system "line" studied by Graves, and so on).
Gardner pointed out that each "intelligence" follows its own distinctive path of development (i.e., you could be very "highly developed" in one intelligence, but mildly "retarded" in another, as we see with savant syndrome). Gardner also suggested each of the intelligences correlate to distinct structures within the brain, each with their own distinctive neurological path of development, as well.
That being said, he also acknowledges fairly universal 'stages' or 'structures' that each line of intelligence passes through (although in a different form for each intelligence) in a hierarchical fashion.
Interesting discussion. Thanks for starting the thread.
