Consumers in a queue feel negatively because they do not know how long they must wait. If an item is worth waiting for, consumers would choose waiting for buying the privilege to get the goods. Hence, this study used personality traits for grouping participants to compare the cognitive situation among traits. This study adopted a brainwave instrument using situational simulation to explain the cognitive response of the decision of hiring queuers by negative emotion and waiting time perception. In addition, this study also adopted a questionnaire to measure the cognitive situation of negative emotion and the waiting time perceptions of the participants. The experiment results showed that the amplitude of contingent negative variation of the ones choosing hiring queuers are significantly different to the other ways. The survey results showed that the negative emotions significantly influence the decisions of the hiring queuer.
