As she was about to meet her new professor for the first time, Petra caught a fleeting glimpse of the angry face of a student behind her reflected in the window of the office door. A split-second later she looked in on her professor, who was calmly sipping a cup of coffee at his desk. "I don't like that guy," Petra muttered. "This is going to be bad." What process colored Petra's initial perception of her professor?
◦ Petra realized that she had met the professor before in an earlier class, and he had been rude and dismissive.
◦ Petra studied the professor's face, mannerisms, and posture, and calculated a "perception ratio" of his likely good and bad qualities.
◦ Petra was influenced by her subliminal exposure to an angry face right before seeing the professor's neutral expression.
◦ The professor resembled Petra's previous dating partner, and they had broken up on bad terms.
