'Preparedness' and the development of aversive associations

The paper presents two studies investigating the role of the preparedness value of stimulus content in an aversive compound signal conditioning procedure. It was predicted that greater compound to component transfer would occur to 'potentially phobic' compared to 'neutral' stimulus components, and that responses to potentially phobic components would show a relatively greater resistance to extinction. Results from both studies failed to support these hypotheses thus questioning the generality of the previously demonstrated role of 'preparedness' in average associative processes.
