The level of processing hypothesis (LoP) postulates several stages of transition from unaware to aware perception. During first stage, low-level processing of stimulus features, awareness is graded and during the second stage, high-level processing, involving semantic evaluation and categorisation, awareness is dichotomous. Studies on electrophysiological correlates of consciousness propose that visual awareness negativity (VAN) is modulated during low-level task and late positivity (LP) changes during high level task (Jimenez et al., 2021), attributing these neural correlates of consciousness (NCC) to different stages and processes. Here we implement the level of processing paradigm using four animal and four object words spoken in different pitches to investigate NCC of auditory consciousness. We predict that awareness will modulate AAN in the low-level task stronger than in the high level-task, LP will be modulated by both level of processing and accuracy. In addition we implement an exploratory factorial mass univariate analysis to find evidence of two parts of LP, recently shown in studies (Filimonov et al., 2022). We will also run the main analysis on two LP time windows. We predict that early LP will be mostly modulated by awareness and the accuracy responding and late LP will be modulated by accuracy and LoP task.

We studied the within-person fluctuations in the prevalence and valence of affect across the wake-sleep cycle with a focus on waking mind-wandering and night-time dreaming. We also compared participants’ self-ratings of affect with external ratings of affective experiences described in verbal reports regarding the same episodes.

The coronavirus (COVID-19, SARS-CoV-2) pandemic poses a major threat to public health and has a large impact on the daily experiences and mental well-being of individuals across the world. Surveys show that a significant percentage of people are concerned about themselves or their family members contracting the virus. These concerns, together with social isolation, are associated with increased levels of mental health issues, such as stress, anxiety, and depression. Despite a surge of empirical studies on COVID-19 related experiences, almost all the studies have been survey studies focusing on peoples’ evaluations of their daily life experiences. However, it is important to investigate how this event has influenced peoples’ subjective experiences across different states of consciousness with a focus on the actual mental content of those experiences. As such, the overall aim of the study is to investigate the mental content of different states of consciousness – dreaming and mind-wandering – during and after COVID-19. The study is carried out online and anonymously via the following website: https://sites.utu.fi/mind/en/ In this pre-reg we fork to an analysis of graph theory metrics of the dream and mindwandering reports.
