The Role of Sleep Quality in Cognitive Failures and Decision Making

Abstract

The study was conducted to examine the role of sleep quality in cognitive failures and decision-making. A total of 200 participants were taken into consideration (n=200), for the purpose of this study from Delhi NCR region between the age group 18- 35 years. They were surveyed using the Pittsburgh Sleep Quality Index (PSQI), Cognitive Failures Questionnaire 2.0, and Flinders decision-making questionnaire. The correlation analyses revealed significant associations between several sleep quality components and decision-making as well as cognitive failures. Notably, better overall sleep quality, as indicated by higher total sleep quality scores, was positively correlated with enhanced decision-making abilities and negatively correlated with cognitive failures. Some specific sleep quality dimensions, such as poor sleep efficiency, longer sleep latency, and shorter sleep duration, exhibited negative correlations with decision-making and positive correlations with cognitive failures. The regression analyses revealed that Daytime dysfunction and sleep duration emerged as significant positive predictors of decision-making performance.
