Two studies related attribute importance to accessibility and speed of judg
ment. Attitudes were assessed by a direct attitude measure and a modal set
of 15 attributes. Attributes were rated in terms of their probability; and
desirability. Subsequently, participant were required to select the five at
tributes the) considered to be most important. Results of Study 1 (dealing
with attitudes towards condom use) show that individually selected, importa
nt attributes are more easily retrieved and judged faster than non-selected
, less important attributes. Judging attributes took less time than evaluat
ing one's overall attitude, suggesting a bottom-up process in which the var
ious attributes are combined to form an overall attitude. Study 2 (dealing
with attitudes towards smoking) extends these findings and also addresses t
he stability of attitude structure. important attributes were again associa
ted with reduced response times, and attribute-related judgments took less
rime than judging one's overall attitude, Accessibility of important attrib
utes remained stable over time as indicated by the results of a lexical dec
ision task one week later. Finally, important attributes were also recalled
better than less important attributes. implications for research on attitu
de structure are discussed.
