    The effect of subgroup homogeneity of efficacy on contribution in public good dilemmas
    (PLOS, 2018-07-31) Yam, Paton Pak Chun; Ng, Gary Ting Tat; Au, Wing Tung; Tao, Lin; Lu, Su; Leung, Hildie; Fung, Jane M. Y.
    This paper examines how to maximize contribution in public good dilemmas by arranging people into homogeneous or heterogeneous subgroups. Past studies on the effect of homo- geneity of efficacy have exclusively manipulated group composition in their experimental designs, which might have imposed a limit on ecological validity because group membership may not be easily changed in reality. In this study, we maintained the same group composi- tion but varied the subgroup composition. We developed a public good dilemmas paradigm in which participants were assigned to one of the four conditions (high- vs. low-efficacy; homogeneous vs. heterogeneous subgroup) to produce their endowments and then to decide how much to contribute. We found that individuals in homogeneous and heteroge- neous subgroups produced a similar amount and proportion of contribution, which was due to the two mediating effects that counteracted each other, namely (a) perceived efficacy rel- ative to subgroup and (b) expectation of contribution of other subgroup members. This paper demonstrates both the pros and cons of arranging people into homogeneous and het- erogeneous subgroups of efficacy.

    True versus strategic fairness in a common resource dilemma: Evidence from the dual-process perspective
    (Wiley, 2018-12-03) Lu, Su; Au, Wing Tung; Zhu, Yi; Jiang, Feng
    Common resource dilemmas involve collectively coordinating individual choices to promote group efficiency. Equal division represents one of the most important coordination rules. Previous research suggests that individuals follow the equality rule for different reasons. Some individuals behave cooperatively out of their concern for other’s welfare, whereas some individuals cooperate strategically to enhance personal gains. Building on the dual-process perspective, the authors aim to differentiate strategic fairness from true fairness in solving a resource dilemma. In four experiments, the effect of cognitive processing manipulations on individual harvesting behavior in a one-shot resource dilemma was tested against participants with different social values. Results consistently showed that prosocials, who value joint outcome and equality, requested significantly less money than did proselfs, who value personal gain. More importantly, prosocials in the intuition and deliberation conditions request similar amounts, whereas proselfs in the intuition condition request more money than those in the deliberation condition. The results were further validated by a follow-up meta-analysis based on the four experiments. The implications of the dual-process perspective for social coordination research are discussed.

    Up or Down? How Culture and Color Affect Judgments
    (Wiley, 2013-08-21) Jiang, Feng; Lu, Su; Yao, Xiang; Yue, Xiadong; Au, Wing Tung
    In the Mainland China stock market, an upmarket is represented by the color red, whereas a downmarket is represented by the color green. Elsewhere, including the Chinese Hong Kong stock market, the color representations are the opposite. Three studies were conducted to examine the red-up–green-down effect for Mainland Chinese as well as the green-up–red-down effect for Hong Kong people. Study 1 showed that Mainland Chinese tended to predict greater economic growth (study 1a) and higher growth in consumption trends (study 1b) when the experimental materials were presented in red than in green, whereas Hong Kong participants exhibited the opposite tendencies. Study 2 found that Mainland Chinese implicitly associated red and green with up and down, respectively; Hong Kong people, however, implicitly associated green and red with up and down, respectively. Study 3 further indicated that Mainland Chinese were more likely to predict good outcomes when scenarios were presented in red, whereas Hong Kong participants were more likely to predict good outcomes when scenarios were presented in green. These findings suggest that culturally specific environment cues could influence human prediction and judgment. Implications for judgment generally are discussed.
