反馈信息类型与效价对公众科学志愿者参与表现激励效应的实验研究

Purpose/significance] Providing feedback is an important design to motivate volunteers and enhance their participation. This research aims to study the motivational impact of feedback information on volunteers' participation performance, in order to provide guidance and suggestions for designing citizen science project and improving volunteers' performance.[Method/process] By using the feedback intervention theory as an overarching framework, this paper integrated social cognition theory and flow theory and proposed a model to depict the influence of feedback type and feedback valence on volunteers' experience and performance in citizen science projects. This study also discussed the interaction effects between feedback type and feedback valence. A 2 (feedback type:descriptive vs. evaluative)×2 (feedback valence:positive vs. negative) between-subject experiment was conducted to validate the proposed research model.[Result/conclusion] Results showed that feedback type and feedback valence have varying impact on volunteers' experience. Volunteers had higher self-efficacy in evaluative feedback than in descriptive feedback; and they had higher self-efficacy and flow experience in positive feedback than in negative feedback. Moreover, there was a statistically significant interaction between feedback type and feedback valence on self-efficacy. For negative feedback, volunteers had higher self-efficacy in evaluative feedback than in descriptive feedback. Volunteer's participation experience had a positive effect on participation performance.
