Our prior studies suggested that consumers perceive standard accents more favorably regardless of whether they were focused on accent or believe the accent is diagnostics. This halo-effect occurred both when the accent had traits that were incongruent with the desired product (Study 3). Study 4 further tests the impact that accent standardness can have on evaluations by examinating whether standard accents influence evaluations even when information more diagnostic than the accent is present. By changing the perceived strength of specific arguments in the message, we are able to examine the underlying process more closely to see whether standard accents can make individual arguments more persuasive, thereby changing the persuasiveness of the entire message.
