This research aims to investigate the relationship between time orientation (past, future, and present orientation) and the decision making styles of Vietnamese customers when they decide to purchase a audiovisual product. A survey was conducted on 423 Vietnamese customers in Hanoi in 2016. The results demonstrate significant relationships between perspectives of time orientation and customer’s decision-making styles. Among the three time perspectives, the past and future orientation manifest a significant difference between decision making styles (customer segments). The present orientation was shown to have significant relationships with some individual characteristics of decision-making style, but no significant difference found between decision-making styles.
