Abstract

ASBTRACT

BACKGROUND: The complexity of current organizations implies a potential overload for workers. For this reason, it is of interest to study the effects that mental workload has on the performance of complex tasks in professional settings.

OBJECTIVE

The objective of this study is to empirically analyze the relation between the quality of decision-making, on the one hand, and the expected and real mental workload, on the other.

METHODS

The study uses an ex post facto prospective design with a sample of 176 professionals from a higher education organization. Expected mental workload (Pre-Task WL) and real mental workload (Post-Task WL) were measured with the unweighted NASA-Task Load Index (NASA-TLX) questionnaire; difference between real WL and expected WL (Differential WL) was also calculated; quality of decision-making was measured by means of the Decision-Making Questionnaire.

RESULTS

General quality of decision-making and Pre-Task WL relation is compatible with an inverted U pattern, with slight variations depending on the specific dimension of decision-making that is considered. There were no verifiable relations between Post-Task WL and decision-making. The subjects whose expected WL matched the real WL showed worse quality in decision-making than subjects with high or low Differential WL.

CONCLUSIONS

The relations between mental workload and decision-making reveal a complex pattern, with evidence of nonlinear relations.

摘要

摘要

背景：当前组织的复杂性意味着员工可能会不堪重负。因此，研究心理负荷对专业环境中复杂任务绩效的影响具有重要意义。

目的

本研究的目的是实证分析决策质量与预期心理负荷和实际心理负荷之间的关系。

方法

本研究采用事后前瞻性设计，样本来自一个高等教育机构的176名专业人员。使用未加权的NASA任务负荷指数（NASA-TLX）问卷测量预期心理负荷（任务前心理负荷）和实际心理负荷（任务后心理负荷）；还计算了实际心理负荷与预期心理负荷之间的差异（差异心理负荷）；通过决策问卷测量决策质量。

结果

决策的总体质量与任务前心理负荷的关系符合倒U形模式，根据所考虑的决策具体维度略有变化。任务后心理负荷与决策之间没有可验证的关系。预期心理负荷与实际心理负荷匹配的受试者在决策方面的质量比差异心理负荷高或低的受试者差。

结论

心理负荷与决策之间的关系呈现出复杂的模式，存在非线性关系的证据。
