The somatic marker hypothesis is one of the more dominant physiological models of human decision-making and yet is seldom applied to decision-making in financial investment scenarios. This study provides preliminary evidence about the application of the somatic marker hypothesis in investment choices using heart rate and skin conductance response measures. Twenty undergraduate students were split equally into expert (defined by familiarity with investments) and novice (no familiarity) groups, because previous research has associated expertise with cognitive differences in decision making scenarios. Both groups completed the Balloon Analogue Risk Task and Behavioral Investment Allocation Strategy task—a computerized simulation of real trading scenarios—as assessments of investment decision-making in conditions of low versus high uncertainty, as defined by the Bayesian calculation (level of certainty is more than: (1 − (−300%))/(300% − (−300%)) = 66.67% (0.67). Results suggest that, although primary inducers (innate physiological responses) support and guide optimal decision-making in conditions of uncertainty, secondary inducers (physiological responses dependent on memory/experience) moderate this effect; that is, the stressful thoughts that accompany the task restrict optimal decision-making. This study contributes to the current knowledge on why emotions in finance can lead people to suboptimal decisions.

关于应用于投资选择的躯体标记假设的初步证据。

躯体标记假说是人类决策的主要生理模型之一，但很少应用于金融投资场景中的决策。本研究提供了关于使用心率和皮肤电导反应措施将体细胞标记假设应用于投资选择的初步证据。20 名本科生被平均分为专家组（定义为对投资的熟悉程度）和新手（不熟悉）组，因为之前的研究将专业知识与决策场景中的认知差异相关联。两组都完成了气球模拟风险任务和行为投资分配策略任务——真实交易场景的计算机模拟——作为对低不确定性和高不确定性条件下的投资决策的评估，次要诱导剂（依赖于记忆/经验的生理反应）缓和这种效应；也就是说，伴随任务而来的压力想法会限制最佳决策。这项研究有助于了解为什么金融中的情绪会导致人们做出次优决策。次要诱导剂（依赖于记忆/经验的生理反应）缓和这种效应；也就是说，伴随任务而来的压力性想法会限制最佳决策。这项研究有助于了解为什么金融中的情绪会导致人们做出次优决策。
