Studies have shown that individuals with hearing loss or who are listening to degraded speech – think of a loud room -- have greater difficulty remembering and processing the spoken information than individuals who heard more clearly. Now researchers are investigating whether listening to accented speech similarly affects the brain's ability to process and store information. Their preliminary results suggest that foreign-accented speech, even when intelligible, may be slightly more difficult to recall than native speech.
