Garcia’s work also laid bare the problems with the domain general aspect of associationism. In the above study the rat was prepared to associate the nausea with the gustatory stimulus, but would not associate it with the audiovisual stimulus. However, if one changes the US from feeling nauseated to receiving shocks in perfect contiguity with the audiovisual and gustatory stimuli, then the rats will associate the shocks with the audiovisual stimulus but not with the gustatory stimulus. That is, rats are prepared to associate audiovisual stimuli with the shock but are contraprepared to associate the shocks with the gustatory stimulus. Thus, learning does not seem to be entirely domain general (for similar content specificity effects in humans, see Baeyens et al.  1990).[33]
