Paper Abstract:
|
In the present study, we explored the possibility that approach to information search, as indexed by the number of presses
and instructions, is related to personality. Participants performed navigation tasks on a Personal Digital Assistant (PDA),
as well as a questionnaire that measured the big-five personality dimensions. A cluster analysis conducted on the
personality dimensions revealed three groups with distinct personality profiles. Individuals who exhibited moderate levels
of neuroticism and extraversion made the most presses that were exploratory in nature and required the fewest
instructions. By contrast, the two other groups (high neuroticism, low extraversion and low neuroticism, high
extraversion) made less exploration-related presses. However, individuals in the high neuroticism, low extraversion group
required a greater number of instructions to assist with task completion and reassurance that they performed the task
correctly. The findings point to the possibility that certain combinations of personality characteristics results in various
approaches to information search. The findings suggest that system organization and training procedures aimed at
facilitating efficacy and efficiency should also take into account personality variables. |
