1. Linguistic intelligence reflects the ability to read, write, tell stories, and learn languages, grammar, and syntax. Strengthen this ability by studying a new language, improving vocabulary, and writing.

2. Your friendly computer programmer has logical-mathematical intelligence. She’s comfortable with numbers, logic, reasoning, and abstractions. To increase logical ability, get a book of logic games, knit a sweater, and learn computer programming. Or watch a movie on video, and stop it to predict what will happen.

3. Those with strong musical intelligence are sensitive to sounds, tones, rhythms, pitch, musical keys, and structure of the songs (from verse and chorus to symphonies). Borrow different types of music CDs, sing with the radio, be quiet and listen to the sounds around you.

4. Those with strong spatial intelligence can imagine, understand, and represent the visual-spatial world. They may have a good sense of direction, hand-eye coordination, and visual memory. Some people, for instance, can visualize how furniture fits in a room without measurements, or buy a scarf that matches the blue in a blouse at home (perfect “chromatic pitch.”) To strengthen your spatial intelligence, be a backseat driver and provide directions for a trip, fit the groceries in the bag or the car, play with jigsaw puzzles and mazes, build some Lego’s, or sculpt some clay.

5. Remember Gene Kelly performing “Gotta Dance!” in Singing in the Rain? He had bodily-kinesthetic intelligence, as do athletes, builders, actors, or surgeons (if they have fine motor skills). Yoga is a great way to increase this ability. Make crafts or build, ride a bike, dance, and learn tai chi or other sports.

6. Someone with interpersonal intelligence is good at organizing people and is aware of moods and motivations. He or she can communicate and lead well. To get more people skills, practice active listening—that is, repeat back what you think someone said. Learn about the types of personalities with the Myers-Briggs test (psychological preferences such as extraversion and introversion) or the Enneagram (a theory of nine personality types—possibly centuries old).

7. Intrapersonal intelligence is the ability to be self-aware and explore emotions, goals and motivations. This perspective on the human condition is used by writers, philosophers, psychologists, and theologians. To improve your intrapersonal intelligence, “know thyself”—write in a journal, meditate, try the personality tests mentioned above.

8. Individuals with green thumbs and “horse whisperers” have naturalistic intelligence. They are sensitive to nature and may easily recognize and classify species. To get more naturalistic intelligence, expose yourself to the great outdoors: plant a seed, volunteer at an animal shelter, take a walk with a naturalist at the park, read about classifications of animals (kids’ books can be a great place to start).

9. Spiritual or existential intelligence fits all Dr. Gardner’s criteria except for association with a specific brain specialization—though this intelligence could be a whole-brain function. Those with this ability explore questions about life, death, and what lies beyond the subjective perspective. Prayer and meditation increase whole-brain communication and lessen the blood flow to the parietal lobes (which give a subjective sense of time and space). Explore what lies beyond through inquiry, reading, or talking with others.
