We examined Chinese adolescents’ aspirations and explored the relationship between relative intrinsic aspirations (RIA) and prosocial behaviors and whether adolescents with different levels of RIA have different emphases on self- and other-oriented considerations during prosocial decision making. In Study 1, 236 participants were recruited and completed a questionnaire containing the Aspiration Index and Prosocial Tendencies Measure. The results show that RIA are positively associated with adolescents’ prosocial behaviors. In Study 2, 158 adolescents completed a questionnaire containing the Aspiration Index and measurements of prosocial decision making and considerations in prosocial decision making. To some extent, adolescents with a lower level of RIA have a greater emphasis on self-oriented considerations, whereas adolescents with a higher level of RIA have a greater emphasis on other-oriented considerations. In addition, both studies suggest that Chinese adolescents value intrinsic aspirations above extrinsic ones.
