Carry-over or prediction? Investigating the predictive coding model using an auditory listening task

Inhaltsverzeichnis (Table of Contents)

• Abstract
• Introduction

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This study aims to investigate the predictive coding model in the auditory domain, focusing on whether auditory predictions carry specific information about upcoming auditory events. The study seeks to provide further evidence for the findings of Demarchi et al. (2018), particularly addressing the possibility of a carry-over effect confounding their results.

• Predictive coding theory and its role in sensory processing
• Auditory predictions and their influence on perception
• The role of top-down predictions in reducing sensory redundancy
• The neural code of predictions and its relationship to actual sensory input
• The use of omission trails to decouple top-down prediction activity from bottom-up activity

Zusammenfassung der Kapitel (Chapter Summaries)

• Abstract: The abstract introduces the concept of predictive coding, its role in perception, and the study's objective to further investigate the predictive coding model in the auditory domain. It highlights the use of omission trails in the study and the aim to rule out carry-over effects.
• Introduction: This chapter delves into the concept of predictive coding, exploring the theory's origins, mechanisms, and its implications for understanding how the brain processes sensory information. It discusses the role of predictions in reducing sensory redundancy and explores the relationship between top-down predictions and actual sensory input. The chapter also reviews previous research on auditory prediction, including studies using repetition suppression and omission trails.
