Motor/behavior output Painful stimulus fear response Sound orienting response Food appetitive response Member opposite sex sexual response Controls? what to compare the conditioned animal to? A na´ve dog (within or between design) A CS control group (bell only) A US control group (meat only) A group with CS?s and US?s presented randomly Extinction trials: presenting the CS (bell) without the US (food) The strength of the conditioned responses can be quantified The magnitude of the CR compared with the UR
