This research was designed to examine the task-media fit hypothesis, an ext
ension to media richness theory that predicts the objective performance of
various media for a number of task types. To examine this model, dyads comm
unicating through face-to-face, videophone, telephone (i.e., audio-only com
munication), or synchronous computer-mediated communication worked in a lab
oratory experiment to address an intellective or negotiation task. The inte
llective task required that each dyad member effectively share factual info
rmation that each individual independently held. The negotiation task requi
red that each dyad member effectively share preferences based on personal v
alues and reach an agreement. The results of the study provide mixed suppor
t for the task-media fit hypothesis. In general, the results for the negoti
ation task largely supported the theory while the results for the intellect
ive task did not support the theory. These results help to clarify limitati
ons and provide extensions to the theory by demonstrating how variations in
task processes and communication media act to mediate task performance. Th
e implications of these results for future research and practice are discus
sed.
