Abstract:  Examined high school studentsknowledge and beliefs about television advisory warnings. 1,854 10th and 12th grade students completed surveys in 1993 concerning television advisory warnings adopted in 1993; 1,489 10th and 12th grade students completed surveys in 1994. Results show that most Ss reported having seen a warning concerning programs with violent or sexual content. Over time, Ss became more aware of the advisories and had more accurate recall of the violence advisory warning. Although this was the case, Ss’ advisory-related beliefs and the amount of violence they watched on television remained unchanged. It is concluded that advisory warnings inform viewers about the content, but that behavior is not necessarily modified by that knowledge. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
