To assess the influence of self-esteem on interpersonal attraction, researchers commented on college students' physical appearance either by insulting or complimenting them just before they went on a blind date. At the end of the date, the students were asked to rate their attraction to their blind date. In this research, what is the independent variable?

* Type of physical appearance comment- type of comment that is given to the participants Size of sample matters.

A hypothesis is:

* a specific statement about behavior or mental processes that is tested through research.

What is the dependent variable in the study described in Question #3?

*Ratings of attraction- outcome of experiment

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)

Volunteer bias

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
