    Abstract: The term “risk-domain specificity” refers to the domain-specific nature of risky decision making due to the presence of factors that are particular to a certain content domain. Based on classical risky decision making theories stemming from laws of expectation, risk-taking propensity is domain-general. On the other hand, substantial evidences from past studies indicate that risk-taking propensity is domain-specific. The literature on risk-domain specificity has witnessed considerable progress in terms of mechanisms, measurements, and independent variables. Theoretically, early mainstream mechanisms deconstructed risk behavior based on a risk-return framework, whereas recent studies have validated the mechanisms with new sets of evidence and explained risk-domain specificity from the perspectives of evolution, personality and motivation. In terms of measurements, Domain-specific Risk Taking Scale (DOSPERT), as a dominant scale, has been further validated in various cultures, content domains, and groups. In comparison, other scales based on different content domains have been proven to be consistent and valid. In terms of independent variables, the regularity of risk-domain specificity has been proposed from various perspectives, such as genetics, environment and individual differences. Future research may focus on content domain integration and theory validation in detailed content domains as well as exploring regularity and mechanisms of risk-domain specificity at an individual level.

    Abstract: Time preference for health is omnipresent and important at both individual and national levels. For a long time, research in this field has been limited to following inter-temporal choice models and methods in the traditional monetary domain of time preference studies. Given the domain-specificity of time preference in the health domain, these indiscriminately theoretical models led to inconsistent measures and results in the field. In the past few decades, researchers in this field have focused on the behavioral consequences of time preference for health. Most studies reported that lower temporal discount rates and higher future time perspectives are positively related to health protection behaviors and negatively related to health risk behaviors. Researchers also found that features of both decision-making objects and decision makers are key impact factors for time preference for health. Future studies should develop theoretical models and measurements that are more suitable to the time preferences for health domain, identify the relationship between healthy behaviors and time preference, and investigate the mechanism underlying the decision-making process. Future researchers should also explore interventions for health behaviors and their application to formulation of healthcare policies.

    Abstract: The global challenge of organ shortage has grown severe in China because of its large population base. To explore the possible means of solving the serious gap caused by demand imbalance, this study attempts to draw lessons from psychological effects, such as default option effect and choice architecture to improve the overall rates of organ donation and number of organs donated. Specifically, we investigated the influence of the organ donation system and registry form design on organ donor registry participation by conducting three online surveys among college students in China. In Study 1, we compared the organ donation rate of people with a Chinese cultural background under the “opt-in” and “opt-out” systems. The results were consistent with those of foreign studies that the organ donation rate under the “opt-out” system was significantly higher than that under the “opt-in” system. To examine the optimal design of registry forms under these systems, Study 2 compared the organ donation rates under the organ donation registry forms of different countries/regions between these systems. In the “opt-in” system, we selected Japan, Texas (USA), and New York (USA), whereas we selected Cyprus and Wales in the “opt-out” system. The organ donation rates of countries/regions under the “opt-out” system did not show any significant differences although they were higher than those of countries/regions under the “opt-in” system. However, Japan (which uses the “rejection response mode” in its registry form) shows a higher organ donation rate than the other countries/regions under the “opt-in” system and even features the same level compared with the countries/regions under the “opt-out” system. To investigate the possible effect of the response mode on the organ donation registry form, we designed a “selection response mode” version of the registry form as the manipulated contrast of the “rejection response mode” and found that both the rate of willingness to donate and the number of donated organs were higher in the rejection response mode than those in the selection response mode. Study 3 mainly focuses on the number of donated organs. We manipulated the response mode and other possible factors in organ donation, namely, the influence on the appearance of donors and the presentation order of organs. Consistent with those of Study 2, the results of Study 3 indicated that using the rejection response mode in registry forms considerably boosted the number of donated organs. Moreover, presenting the organs with the lowest influence on the appearance of donors in an ascending order can reach the highest number of donated organs in rejection response modes. In sum, these results demonstrate that the “opt-out” system and response mode can effectively promote the organ donation behavior in China. Therefore, policymakers may consider the following suggestions to improve the organ donation rates in China: changing its current “opt-in” organ donation system to the “opt-out” system; or, under the current “opt-in” organ donation system, adopting the rejection response mode in registry forms and presenting the organs with the lowest influence on the appearance of donors first.

    Abstract: As an editorial for Acta Psychologica Sinica’s special column, this paper provides a concise overview of the nudge concept and its progress. The necessity of the concept is analyzed, and the main methods and fields of application are summarized. The effects of the concept on the promotion of people’s health, wealth, and happiness are elucidated, and the related disputes are clarified. Several suggestions that may help researchers in carrying out nudge research are also derived. We briefly draw the outlines for several papers in this special column and discuss the outlook for how nudge research should begin in China with the goal of attracting psychologists to devote to nudge research.

    Abstract: Risky choice (RC) and intertemporal choice (IC) are two types of common decisions that are vital to human’s everyday life. RC and IC share similarities regarding theoretical development, behavioral effects, and neural basis. One critical challenge is that, although previous studies have revealed that RC and IC involve similar cognitive processes, results are mixed regarding what the exact mechanism might be. The mainstream discounting model hypothesizes that both RC and IC follow a compensatory and alternative-based rule. However, other models suggest that RC and IC commonly involve non-compensatory and attribute-based processing. Moreover, prior studies primarily based their findings on outcome data and few have attempted to determine whether RC and IC shared a common decision process at the cognitive computational level. To fill this gap, the present study adopts a systematic approach to disentangle the exact mechanism of RC and IC. We considered two well-studied behavioral effects, namely, certainty effect of RC and immediacy effect of IC, respectively, and compared their underlying local and holistic process characteristics by using eye-tracking technique. Besides, we employed hierarchical Bayesian modeling to assess whether alternative- or attribute-based models better fit both RC and IC. We designed a 2×2 within-subject paradigm, with the choice task (RC vs. IC) and the construct of decision options (with vs. without certain/immediate option) as factors. Thirty-three postgraduate students participated in our study. As we were particularly interested in two pairs of decision rules, i.e., compensatory/non-compensatory rules and alternative-based/attribute-based rules, we included a series of decision attributes that reflected them, based on the local and holistic process characteristics derived from eye-movement data to test our hypotheses. Our entire set of analyses aimed to (1) determine whether the decision processes of RC and IC are similar and (2) identify the best computational model that is more suitable for both decisions. For the first aim, results show that RC and IC indeed share comparable decision processes, albeit having a few differences in other aspects. Specifically, RC and IC differ in process characteristics, such as complexity and holistic eye-movement dynamics, and IC is processed in a relatively more deliberate, deeper fashion than RC. However, they are similar in other characteristics, such as search direction, which is more relevant to making decisions. For the second aim, computational modeling of process characteristics suggests that both types of decisions are consistent with non-discounting models. In particular, results of search direction, in light of Bayesian model comparison, reveals that participants are more likely to follow the non-compensatory, attribute-based rule rather than the alternative-based/attribute-based rule when deciding for both RC and IC. Furthermore, different task constructs of decision options, i.e., with or without certain/immediate option, show distinct process characteristics, such as direction, complexity, and depth in both RC and IC.To conclude, the present study shows that although differences exist between RC and IC, they indeed have shared cognitive mechanisms at the core of the decision processes. In both types of decisions, contrary to classic discounting models, individuals seem not to follow compensatory, attribute-based rules, which undergoes a “weighting and summing” or “delay discounting” process. Instead, they are more likely to use simple heuristic rules hypothesized by non-discounting models. Moreover, when including certain or immediate options, individuals tend to follow less compensatory and non-dominant (neither attribute-based nor alternative-based) rules. In sum, our findings not only provide a theoretical and empirical basis for the establishment of a common framework for RC and IC, but also provide a novel direction for thorough theoretical and methodological comparisons between variant decision tasks.
