Depiction of aversive conditioning components of experimental paradigm. Participants are presented with two counterbalanced aversive conditioning sessions following a gambling game where they earn a monetary endowment. (A) In the first session, the unconditioned stimulus is a mild electric shock (primary reinforcer) which is paired with a colored square (sCS+). (B) In the second session, the unconditioned stimulus is a monetary loss (−$6.00), which is paired with a different colored square (mCS+) and detracted from the total sum earned during the gambling game.
