Abstract

© 2019 Elsevier Ltd Studies of the neural correlates of consciousness (NCCs) combining MEG/EEG with behavioral data have described two main time ranges relating to conscious perception: 130–320 (the visual awareness negativity; VAN) and 300–500 (P3a) ms after stimulus onset. At the same time, two event-related potential (ERP) peaks have shown an emotional modulation of endogenous attention: the early posterior negativity (EPN; peaking around 250 msec) and the late positive potential (LPP, peaking around 600 msec). Furthermore, an emotional bias on conscious perception has been reported in Binocular Rivalry (BR) studies. Here, we combined an intermittent BR paradigm with neutral and emotional stimuli while recording the behavioral subjective perception and ERPs with two aims: i) to explore the NCCs of emotional content in the time ranges previously described, and ii) to study the emotional bias in conscious perception as first percept when neutral and emotional images rival against each other. First, results revealed a specific ERP emotional modulation (emotional content awareness modulation; ECAM) at the VAN time range. This was the first time window sensitive to the emotional information and showing the strongest modulation in conscious emotional content. Second, results revealed an emotional bias in conscious perception towards the positive valence. This work shows how conscious perception pertaining to emotional content relates to perceptual areas at the VAN latency, which supports the claim of the 130–320 msec time window as the earliest NCC and extends the claim to apply to more than visual perceptual features. Additionally, our findings show that positive and negative content modulates the conscious perception differently.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-09:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 44.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 44 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 5.85.
  • The number of mentions on the social network X (formerly Twitter): 9 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
