This study examines the impact of public screen and task types on cons
ensus change and influence equality in a GSS environment. The research
ers employed a controlled laboratory experiment with 44 five-person gr
oups. The independent variables were public screen type and task type.
Two kinds of public screens were studied: common and individual. Two
task types were examined: intellectual and preference. The dependent v
ariables were consensus change and influence equality. The findings we
re that a common public screen promotes consensus change with the pref
erence but not the intellectual task. Moreover, individual public scre
ens and the intellectual task encourage influence equality.
