The current experimental study investigated human sharing within a laboratory task that modeled environmental variability. In particular, it sought to assess the efficacy of a risk-reduction model of sharing, which originated from a risk-sensitive optimization model known as the energy-budget rule. Participants were given the choice between working alone or cooperating and sharing accumulated hypothetical earnings with a fictious partner. Failure to acquire sufficient money resulted in a loss of accumulated earnings. To investigate the effects of economic context on sharing, the difficulty of meeting an earnings requirement was manipulated across conditions by changing the monetary requirement that needed to be met in order to bank earnings, which could later be exchanged for real money. In some conditions sharing was the optimal strategy (positive budget conditions), sometimes working alone was optimal (negative budget conditions), and other times neither option was optimal (neutral budget conditions). Gender differences were examined within this context to determine if males and females differed in their sharing behavior. The results suggested that males chose the sharing option more often in the positive budget condition and showed a stronger preference for the work-alone option in the negative budget condition than females.

当前的实验研究调查了模拟环境变化的实验室任务中的人类共享。特别是，它试图评估共享风险降低模型的有效性，该模型源于被称为能源预算规则的风险敏感优化模型。参与者可以选择单独工作或与虚构的合作伙伴合作并分享累积的假设收入。未能获得足够的资金导致了累积收入的损失。为了研究经济环境对共享的影响，通过改变需要满足的货币要求来控制满足收入要求的难度，以便将收入存入银行，随后可以兑换成真实货币。在某些情况下，共享是最佳策略（正预算条件），有时单独工作是最佳策略（负预算条件），而其他时候这两种选择都不是最佳策略（中性预算条件）。在此背景下检查性别差异，以确定男性和女性的分享行为是否不同。结果表明，在正预算条件下，男性比女性更频繁地选择共享选项，而在负预算条件下，男性更倾向于单独工作选项。
