“…Research on negative campaigning effects has produced over the years a wealth of results on a wide range of attitudes and behaviors, such as attention to and memorability of information (Lau, ), election outcomes (Lau and Pomper, ; Mattes et al., ), strength of issue ambivalence (Nai, ; Lanz and Nai, ), approval of Congress (Globetti and Heterington, ), information search (Lau and Redlawsk, ); support and affect for the attacker (Arceneaux and Nickerson, ; Hitchon and Chang, ; Kahn and Kenney, ; Pinkleton, ), affect for the target (Arceneaux and Nickerson, ; Fridkin and Kenney, ; Kahn and Kenney, ; Pinkleton, ), cynicism (Cappella and Jamieson, ; Valentino et al., ; Yoon et al., ), and turnout (Ansolabehere and Iyengar, ; Ansolabehere et al., ; Nai, ; Kahn and Kenney, ; Lau and Pomper, ). Such research has, however, failed in providing a unified framework on negative campaigning effects.…”
