Gardener's Multiple Intelligences

linguistic, logical - mathematical, musical, spatial, bodily - kinesthetic, interpersonal, interpersonal, naturalist intelligence - measures different angles and parts of learning (so, if they are separable things, they shouldn't correlate, but they DO correlate, so it suggests there is one fundamental generalized ability) - questions: does it measure intelligence or just talent

windt: consciousness is

main psych focus

mental age vs chronological age

measure of how intelligent you are vs your chronological age, no way it is immovable or innate

intelligence

John Raven (1938)

progressive materials visual problem solving less culturally biased

does free will exist? libet experiment

proves that conscious thought does not control actions, there is no free will "consciousness of a decision may be a mere biochemical afterthought, with no influence whatsoever on a person's actions."

Assessing validity: criterion-related validity =

relationship between scores on a test and an independent measure of what the test is supposed to measure

behaviorism is just

speculation

qualities of a good test

standardized: pretested to a representative sample of people and from a normal distribution or bell curve reliable: extent to which a test procedures consistent and results valid: extent to which a test measures what we want it to measure, SAT's predict college success?

consciousness

subjective experience of the world and your mental activity, moment by moment subjective experiences reflecting on one's current thoughts or paying attention to one's immediate surroundings, a view from within, inner experience, WHAT WE LOSE WHEN WE SLEEP, awareness

The activity spreads through much more of the brain.

On average, how do dreams differ from daily life?

They are more likely to include unhappy emotions.

People watched a dot moving around a clock and spontaneously decided when to flex their wrist, remembering and later reporting the location of the dot at the time of the conscious decision. Researchers also measured the time activity increased in the Premotor cortex, and the time of the wrist movement. Why were the results theoretically important?

They suggest that conscious thought does not control our actions.

if the test takes place in late afternoon or evening

what you're seeing
