text: In a human fear conditioning test, yo, ABA-renewal was observed,
  Switchin' up the lighting in the room, that's how it goes,
  In the dark or illuminated, that's the choice they made,
  One slide with a loud noise, the other stayed unswayed.
  
  Then came the extinction phase in the opposite light,
  Tryna wipe away the fear, like day turns into night,
  But when they tested 'em again, back in the original scene,
  The electrodermal response was back, like a bad dream.
  
  Conditioned fear, yo, it made a strong return,
  And the verbal US-expectancy ratings began to churn,
  But no recovery was seen in the AAA-group,
  Same context all the way, no change in the loop.
  
  Yo, there's theories to explain this fear's rebound,
  And implications for clinical practice, profound,
  But that's the deal, my friend, the story's told,
  Fear's a tricky beast, hard to control.
