Does Sleep Restriction Impact Performance and Metacognition in an Episodic Memory Task? An Experimental Study

Inhaltsverzeichnis (Table of Contents)

• Sleep and the effects of sleep deprivation
• Sleep and memory
• Metacognition

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This experimental study investigates the impact of sleep restriction on both episodic memory performance and metacognition. The study aims to determine if sleep restriction negatively affects memory accuracy and two key aspects of metacognitive ability: confidence bias and metacognitive sensitivity.

• The influence of sleep restriction on episodic memory performance
• The role of sleep in metacognitive processes, specifically confidence bias and metacognitive sensitivity
• The potential implications of sleep restriction for decision-making and cognitive errors
• The significance of metacognition for everyday behaviors, including emotion regulation, medication adherence, and performance in various settings
• The relationship between sleep, metacognition, and psychiatric disorders

Zusammenfassung der Kapitel (Chapter Summaries)

• Sleep and the effects of sleep deprivation: This chapter provides a comprehensive overview of sleep, including its evolutionary significance, its various functions, and the different sleep stages. It also discusses the prevalence of sleep deprivation in industrialized countries and highlights the negative consequences of both total sleep deprivation and sleep restriction on cognitive function.
• Sleep and memory: This chapter focuses on the relationship between sleep and memory, particularly long-term memory. It explores the different types of memory, including procedural and declarative memory, and emphasizes the role of sleep in memory consolidation, encoding, and retrieval. The chapter also examines the impact of sleep deprivation on memory performance, particularly within the context of episodic memory.
• Metacognition: This chapter defines metacognition and explores its role in various cognitive processes. It discusses the importance of confidence judgments, differentiating between retrospective and prospective judgments. The chapter then delves into different measures of metacognition, including confidence bias and metacognitive sensitivity, highlighting their significance for decision-making and the potential impact of sleep restriction on these aspects.
