Claude had an unpleasant experience during his last visit to Dallas, Texas. He was approached by two men with strong Texas accents who wielded sharp knives, roughed him up, cracked a rib, and stole all his money. Ever since Claude was mugged, he has taken an instant dislike to anyone who speaks with a Texas twang. Claude's negative attitude toward Texas accents is most probably a result of instrumental conditioning. attitude accessibility. classical conditioning. cognitive dissonance reduction.
