Document Summary
Preparedness = innate tendency for an organism to more easily learn certain types of behaviors or to associate certain types of events with each other. More easily develop fears to animate objects than inanimate objects. Taste aversion conditioning i. e. taste (cs) + radiation (us) nausea (cr) Can work even after just one bad instance; does not necessarily need repetition. Food items that taste similar to the aversive item are also perceived as aversive. If the aversive food item is repeatedly ingested without further illness, the cs (food) may not longer elicit an avoidance response. We are more likely to develop an aversion to a stronger-tasting food item than to a milder- tasting item that was consumed at the same meal. If already have an aversion to one food, it will block developing an aversion to another food. We are more likely to associate a relatively novel item, with sickness than we would a more familiar item.
