  1. US HABITUATION DOES NOT CAUSE RETROACTIVE REVALUATION OF A CONDITIONED FEAR RESPONSE. Stephanie Damas, Cheryl Novak, & Dr. Brian L. Thomas Baldwin-Wallace College

  2. Introduction • NS  No particular response bee • NS + US  UR bee sting pain • CS  CR bee anticipatory fear/avoidance (Pavlov, 1927). • Fear conditioning (Estes & Skinner, 1941).

  3. Introduction • EU: CS not predict US / US not predict CS, (Rauhut, Thomas, & Ayres, 2001). • Fear for a CS is weakened by presenting US until habituation develops, (Rescorla, 1973). • Retroactive revaluation- informational value of CS is changed without actually experiencing it.

  4. Purpose • Is relapse prevented in the EU procedure because the rats become habituated to the US? • Does the intensity of the shock effect habituation directly and revaluation indirectly? • What, if any, importance does shock intensity have in the EU paradigm?

  5. Method

  6. Results: Renewal • Conditioning was stronger with a more intense shock. • Extinction was slower in Group EU .60 than other groups.

  7. Results: Savings Test • EU groups combined greater savings than E groups combined. • E Groups combined greater savings than U groups combined.

  8. Results: Revaluation/Habituation • Conditioning was faster in E groups combined than other groups. • Conditioning was faster in .60 mA groups combined than than .40 mA groups.

  9. Conclusions • The EU procedure is not dependant on US habituation. • US habituation was greater with a .40 mA shock than .60 mA shock, but savings did not depend on shock intensity. • US habituation did not cause retroactive revaluation.
