The General Hypothesis of the Word Et Al

The general hypothesis of the Word et al. study on interaction between whites and blacks is that:

A) black job applicants will respond to what they perceive as whites' negative attitudes toward them with increased friendliness, in an attempt to change the whites' negative evaluations of them.
B) whites and blacks will engage in a sequence of nonverbal, reciprocal interactions that result in a self-fulfilling prophecy.
C) black job applicants will receive the same amount of "immediate" nonverbal communications from a white interviewer as will white job applicants.
D) all recipients of more "immediate" non-verbal communications-regardless of race-will be judged more harshly than recipients of less "immediate" non-verbal communications.
