Answer:
Classical Conditioning
Step-by-step explanation:
Claude's negative attitude toward Texas accents is most probably a result of classical conditioning because it was stated that ''Ever since Claude was mugged, he has taken an instant dislike to anyone who speaks with a Texas twang.''
Ivan Pavlov describes Classical conditioning, to occur when a particular response to a stimulus becomes conditioned to respond to another associated stimulus.
Hence Claude's response to Texans is now associated with being mugged.
