Which of the following about theories of color vision is true?
The opponent process theory of color vision can explain the color in negative after images.
explanation that organizes the observations and predicts behaviors or events
Theory
reflects the prospect that people who offer to participate in research studies differ systematically from people who do not. (if offered money, they will act different than those who don't get offered money)

damage of speech or (difficulty understanding speech)
Wernicke's area
A researcher would be most likely to discover a negative correlation between:
a. salary and years of education.- positive b. studying and GPA.-positive c. stress and health. -negative correlation—when one increases, the other decreases d. self-esteem and academic achievement.-postive
