摘要

人们的决定受到他们对他人福利的关心的影响。他们既可以帮助别人,也可以伤害别人。这些动机的方向和大小可以量化相对于一个人的自身利益作为福利权衡比率(WTR)。这个结构对于检验社会动机的定量理论是有价值的。然而,大多数现有的wtr度量,以及类似的社会价值取向(SVO)结构,都是基于在离散的收益集之间的多重选择,这迫使度量的准确性和效率之间进行权衡。在这里,我们介绍Lambda滑块,这是一种同时准确和高效的WTR测量。参与者使用线性滑块从连续的收益分配范围中为自己和她的社交伙伴进行选择。自我和他人的潜在回报函数在参与者的潜在WTR值和她可以选择的滑块位置之间创建了一对一的对应关系,从而可以从单个响应中精确测量WTR。在三个实验中,我们发现Lambda滑块上的单个响应具有高可靠性,与其他社会动机测量具有高收敛效度,并且对于具有现实世界后果的利他决策具有高外部效度。Lambda滑块易于实现,可以应用于各种关于塑造社会动机的力量的研究。

An accurate and efficient measure of welfare tradeoff ratios.

People's decisions are affected by their interest in others' welfare. They can be motivated both to help and to harm others. The direction and magnitude of these motivations can be quantified relative to a person's self-interest as a welfare tradeoff ratio (WTR). This construct is valuable for testing quantitative theories of social motivation. However, most existing measures of WTRs, and the similar construct of social value orientation (SVO), are based on multiple choices between discrete sets of payoffs, which forces a tradeoff between the accuracy and efficiency of the measures. Here we introduce the Lambda Slider, a WTR measure that is simultaneously accurate and efficient. A participant uses a linear slider to choose from a continuous range of payoff allocations for herself and her social partner. The underlying payoff functions for self and other create a one-to-one correspondence between the participant's potential WTR values and the slider positions that she could choose, which enables accurate measurements of WTR from a single response. Across three experiments, we show that a single response on the Lambda Slider has high reliability, high convergent validity with other measures of social motivation, and high external validity for an altruistic decision with real-world consequences. The Lambda Slider is easy to implement and can be applied in a wide variety of studies on the forces that shape social motivation.
