Abstract: The framing effects of risky decision have for both theoretical and practical reasons received much attention. By using simulated team scale dynamic distributed decision-making task on computer network, three factors (past performance factor, target set factor and start bonus factor) were used to find their influences on decision maker's risk preference. It was found that the target factor had a refrain function on other framing effects and the start bonus factor had different effects on the individual and the team. The results imply that the risk sensitivity can also be used to explain the risk preference in dynamic context.

Key words: framing effects, risk sensitivity, risk preference, start bonus
