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. [--]
