We investigated the gain-loss effect of virtual/personal assistant character, which provides intelligent assistance tohumans, and focused on not only the first impression of using the assistance but also changing impression about the characterwhen used multiple times for assistance. The experiment used a fictive retrieval system (searching onomatopoeia), and thevirtual assistant character looked up for suitable words for the user (success), or failed to find the words (mistake). There werethree sessions, differing by the task of character’s mistake; two tasks were successes and one was a failure in each session. Theresults showed that the group of people who had low expectation from its first appearance, formed negative impressions afterthe final mistake, significantly. Consequently, final mistake influenced the formation of negative impression more than othermistakes, thus showing that the final mistake in multiple times of assistance was associated with loss effect.
