Performance on the serial reaction time (SRT) task reflects gradations of fringe consciousness. A modified SRT procedure with a novel exclusion task better reveals awareness influences and distinguishes fringe consciousness from explicit knowledge.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Consciousness Studies

Background:

  • Serial reaction time (SRT) task performance is linked to awareness, including fringe consciousness.
  • Traditional SRT procedures and exclusion tasks have limitations in assessing awareness.
  • Fringe consciousness, conceptualized by William James, represents a subtle form of awareness.

Purpose of the Study:

  • To address limitations of traditional SRT procedures.
  • To investigate the influence of response stimulus interval (RSI) on awareness.
  • To differentiate fringe consciousness from explicit sequence knowledge using a modified SRT paradigm.

Main Methods:

  • Two experiments using a modified SRT procedure with irrelevant stimulus attributes obscuring the sequence rule.

  • Inclusion of a novel exclusion task to assess awareness.
  • Utilizing the NEO-PI-R (Revised NEO Personality Inventory) to measure individual differences, specifically Openness to Feelings.

    • Main Results:

    • The modified SRT paradigm successfully demonstrated the influence of RSI on awareness.
    • Dissociations between awareness measures identified participants exhibiting fringe consciousness rather than explicit knowledge.
    • Openness to Feelings influenced the diversity of reported subjective feelings but not the degree of learning or awareness.

    Conclusions:

    • The modified SRT procedure effectively distinguishes fringe consciousness from explicit sequence knowledge.
    • Findings suggest potential distinctions between two components of fringe consciousness.
    • Individual differences in Openness to Feelings may relate to subjective experiences within fringe consciousness, but not necessarily to learning or awareness itself.
