Studies of the effect of viewers' involvement in television programs on their responses to commercials have produced varied conclusions. Some researchers argue that a high level of program involvement inhibits viewer processing of commercial messages, a conclusion based primarily on the finding that viewers demonstrate better recall for commercial messages when program involvement is low. For example, Bryant found recall highest for a beverage commercial when it interrupted a minimally involving moving wave pattern, with recall decreasing somewhat when the commercial interrupted a moderately involving portion of an action-adventure show and falling substantially at the program's climax. Krugman, however, argues that the persuasive impact of commercials increases as interest in the program increases. Krugman found viewer attitudes toward a commercial sponsor to be less positive when commercials appeared during programs with "natural breaks” (talk-show and variety segments, assumed to be low-involvement) than when they appeared in an “interrupted context” (movies and documentaries, assumed to be high-involvement). Finally, Lord concluded that certain program content induces viewers to commit a large proportion of their attention to its processing, minimizing the efficiency with which they can process information conveyed by a commercial. This result appears to account for the recall effects observed in earlier studies such as Bryant's. Lord postulated that beginning a commercial with an attention- engaging device would moderate the expected impact of high program involvement.

2. It can be inferred from the passage that Krugman's research differs from Bryant's research in that KrugmanA) assumes that the type of program during which a commercial appears affects viewers' involvement in the commercial
B) concludes that viewers demonstrate better recall for commercial messages when program involvement is high
C) reaches conclusions that are supported by the findings of most studies of the effect of viewers' program involvement on their responses to commercials
D) focuses on viewers' attitudes toward commercial sponsors rather than on viewer recall of commercial messages
E) studies the persuasive impact of commercials rather than viewers' attitudes toward commercial sponsors
3. The primary purpose of the passage is toA) evaluate the methodologies used in certain empirical studies of the effectiveness of television commercials
B) review the results of research on how viewers' level of involvement in a television program can affect the impact of commercials aired during that program
C) explain why empirical research fails to support a particular theory about the effect of viewers' involvement in television programs on the impact of commercials
D) question certain researchers' conclusion that a viewer's level of involvement in a television commercial is determined by the content of the program the commercial interrupts
E) propose ways to counteract the negative effects that a viewer's involvement in a television program may have on the impact of a commercial
