1. 1. The effect of self-referential processing of faces on visual awareness : An ERP study

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Ieva Smate; [2023]
   Keywords : Self-face; awareness; VAN; self-advantage; ERP;

   Abstract : Previous findings have discovered that self-related stimuli such as one’s own face relative to a familiar or an unknown face leads to enhanced neural processing. Preferential processing of the self-face has been observed at various event-related potential (ERP) components, both when stimuli were presented on a subliminal and supraliminal level. READ MORE

3. 2. Is visual consciousness graded? : A comparison of conscious detection and identification

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Josef Gravenfors; [2022]
   Keywords : Visual awareness; levels of processing; graded consciousness; detection; identification;

   Abstract : A current controversy in the science of visual consciousness is whether conscious awareness of a stimulus emerges gradually or appears directly in an all-or-none fashion. Windey et al. READ MORE

4. 3. To see or not to see the error of one´s ways : Consciousness and the Error-Related Negativity

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Noah Kaufman; [2020]
   Keywords : ;

   Abstract : The error-related negativity (ERN) is a widely-used electrophysiological measure of error processing in the brain. Whether the ERN supports conscious awareness of erring has yet to be determined. READ MORE

5. 4. ERP and MEG Correlates of Visual Consciousness : An Update

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Jona Förster; [2019]
   Keywords : Neural correlates of consciousness; Event-related potentials; Event-related fields; Visual awareness negativity; Late positivity; Global Neuronal Workspace theory; Recurrent Processing theory;

   Abstract : Two decades of event-related potential (ERP) research have established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a negative component in the N2 time range over posterior electrode sites, and the late positivity (LP), a positive component in the P3 time range over fronto-parietal electrode sites. A review by Koivisto & Revonsuo (2010) had looked at 39 studies and concluded that the VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas the LP probably reflects later processes associated with reflective/access consciousness.

6. 5. Exploring the Neural Correlates of Auditory Awareness

   University essay from Stockholms universitet/Psykologiska institutionen

   Author : Billy Gerdfeldter; [2018]
   Keywords : consciousness; awareness; audition; event-related potential; auditory awareness negativity; AAN;

   Abstract : Neural correlates of consciousness (NCCs) represent the physiological processes related to consciousness and awareness. Consciousness is theorized as a recurrent process of integration between separate but specialized brain areas. READ MORE
