Nearly this many hours of audio fit on a single CD recorded as an MP3 file:

Jasmine was terrified about having to speak in front of an audience. She was certain that

everyone in the audience would see how her hands were shaking or hear how nervous her voice sounded. She worried that people would laugh at her.  She was surprised when, after the speech, her classmates complimented her on how confident she seemed.  Jasmine?s problem was that A)  she had not practiced her speech enough before class. B) she had not stretched her comfort zone. C) she had not used visual imagery. D) she had been overconcerned about how her audience would respond.

One of the limitations of making generalizations about message variables that have been reported on in multiple studies is:

a. studies may have been conducted in different years b. studies often use the same message to test a given variable c. studies often use different experimental designs d. studies may include different subject populations
