An ice cream truck plays “Old MacDonald Had a Farm.” Children run outside when they hear it playing. Then the ice cream truck changes the song it plays to “B-I-N-G-O.” Even though the song is different, the neighborhood children react the same way. What would a psychologist call this behavior?

The children have learned to respond to the ice cream truck’s song by running outside. They respond the same way when the truck plays a different song, so they are extending the learned response to a new but similar cue. This is generalization; discrimination would mean responding differently to the two songs.
