Time Slice Theory: Is Consciousness as Fluid as We Think It Is?
Our brains have all sorts of shortcuts to help us experience reality more efficiently. For example, you’ve probably seen one of those tests circulating the internet with a sentence full of mispselled wrods taht dno’t raelly inhbit yuor raeding speed, as long as the frist and last lettres in evrey word are unchanged. This phenomenon may be part of a conceptual explanation known as the Time Slice Theory of consciousness, suggesting our minds stitch together a narrative of individual frames, rather than a continuous, live stream.
The paper was published on PLoS-biology by scientists Michael Herzog of the École Polytechnique Fédérale de Lausanne, and Frank Scharnowski of the University of Zurich in Switzerland. Their theory says our brains process reality in individual moments, or what they call percepts, arising in 400 millisecond intervals. These percepts are then stitched together and rendered as a continuously flowing sequence of reality that makes sense to us – much like a movie shot in high definition.
But instead of watching the movie and making judgements as we observe them, our unconscious mind reviews individual images, processes them in an abstract order, and makes subjective judgements based on heuristics from past experience. It then translates those judgements into an apparently fluid narrative, allowing you to efficiently process reality.
Time Slice Theory of Consciousness & Perception
Time slice theory says we only process reality after 400 millisecond intervals, and that there is minimal to no conscious observation between those frames; our brains only collect sensory information at discrete time-points. It is also within this period that our minds frantically work to make sense of it all.
It’s mind-boggling to think our unconscious can work so quickly, but our brains are fascinatingly powerful processors. It’s believed the mind calculates roughly 1014-1016 processes per second, or somewhere between 1 and 100 quadrillion calculations per second. The average computer functions at about half that speed.
So, what exactly happens during that unconscious judgement phase? According to Time Slice Theory, the brain processes specific features of objects, such as color and shape, quasi-consciously or unconsciously with high resolution. Within this moment there is no sense of linear time, in fact, changes in duration or even color aren’t processed. It then draws the necessary connections and stitches them together to pass off to the conscious stage.
Sometimes this period happens instantaneously and other times it takes longer, depending on the complexity of the information being fed to it. Occasionally, this leads to reactions based on false judgements, such as in fight-or-flight instances, but these instincts are naturally made to surpass the logical decision-making process, usually for survival reasons.
For instance, if someone jumps out of a closet and scares you, your unconscious perception recognizes an ostensible threat of unexpected, encroaching movement, in turn telling you to move or attack the stimulus without logical consideration.
Schizophrenics often report a slowed integration process in which the window of logical deduction takes longer and their stream of perception is fragmented.
This seems to parallel Robin Carhart-Harris’ entropic brain hypothesis regarding the Default Mode Network, the region of the brain believed to be responsible for the ego. His theory says that during a psychedelic, creative, or psychotic experience the mind sifts through more possible outcomes than it normally would, drawing from a number of seemingly incorrect conclusions to make sense of what it’s observing; with psychedelics this is what results in visual hallucinations.
Our brains can also draw false conclusions about reality while being completely aware of them. One such instance is known as the Cutaneous Rabbit Illusion; a physical deception in which a syncopated tapping of the wrist and elbow tricks the mind into feeling as if a tiny, invisible rabbit is hopping up the arm. This illusion happens because the mind infers the sensation in between the two areas of stimulation.

A Similar Buddhist Theory of Consciousness
In the third century BC, the Abhidharma Buddhist School first recorded the concept of our brain’s discrete perception of reality. Their scripture refers to the threshold between conscious and unconscious awareness as the “Mind-door,” where we internalize information received through our sensory faculties.
The Mind-door characterizes the mind as the creator of subjective experience which forms the basis of memory and thought, and subsequently the micro-judgements that form the mind’s narrative. They considered the Mind-door to be our sixth sense, transcending time and making purely conceptual judgements.
Abhidharma Buddhists believed when an image reached this threshold, the mind would switch from inactive mode to any of the five-sense processes, based on whichever faculty was appropriate.
These discrete moments were referred to as dharmas – different from the teachings of the Buddha known as the dharma – used to describe experience encountered through the senses. But the dharmas weren’t simply objective experience, rather they are the product of “rapid consciousness that arise and cease in sequential streams, each having its own object, and that interact with the five externally directed sensory modalities of cognitive awareness.”
These dharmas are also described as “psycho-physical events with diverse capacities by means of which the mind unites and assimilates a particular perception, especially one newly presented, to a larger set of ideas already possessed, thus comprehending and conceptualizing it.” Sounds a lot like the Time Slice dynamic.
But Scharnowski and Herzog admit that their theory is purely conceptual and that the argument between a stream of consciousness theory and Time Slice theory remains unsettled. And while theirs is an interesting thought experiment into the way our brain processes consciousness, it doesn’t necessarily do much to answer the hard problem of consciousness itself – that is, what is consciousness?
The answer to that question remains to be understood if it can be understood in this realm at all. For more hints to help you answer such a primordial, existential question watch the documentary PHI: The Evolution of Consciousness:

13 Indigo Children Traits & Signs of a New Age Revolutionary
What is an Indigo Child?
An Indigo Child, sometimes referred to as an Indigo Kid, is believed to be a new generation of individuals with heightened spiritual awareness and unique traits, a concept introduced by parapsychologist, synesthete, and psychic Nancy Ann Tappe, who coined the term to describe the distinctive aura colors of these extraordinary children. Lee Carroll and Jan Tober further developed Tappe’s concept, both international authors and renowned educators and lecturers. Previously, auric fields were expected shades of the rainbow, but a royal blue color dominated the Indigos’ field. Thus, establishing a change of course in human evolution and their indigo aura.
Gifted children, on a clear mission to challenge and shift reality, first began appearing in the 1970s. Beyond psychic awareness, they are highly driven and creative with a perception that sees through the established norms of society. Old souls indeed, their mission is laid out to shake up the modern world and pave the way for future generations to create greater peace and harmony for all.
Both of these generations of “children” are well into their teens and adulthood, so don’t allow the label to dissuade you from exploring the concept of Indigo Children.
