Phenomenal puzzles – CIELAB

Answer sheet to phenomenal puzzle #1:

Phenomenological studies reveal that we have three major qualia-poles that compose all experienced colors. Luminance is the first: How subjectively bright is it? The other two: We obtain red and green on two opposite sides, and blue and yellow on the normal of that pole.



The qualia that you are now experiencing on the left of your sensorium must match the schema to your right. Allow some room for normal human drawing errors. Is the chart similar enough to the subject’s solution to warrant a positive result?

Materials: Tester (t), neural bridge (nb), and entity (e).

Protocol: t and e must read the protocol. Let t read the promt of the phenomenal puzzle. Connect t’s brain to e’s brain with the nb at time t = 0. Adjust the connection setting to 1st person merging (fully unified sense of self). Phenomenal binding between brains is achieved. In that state, the equivalence between qualias in, say, vision, can be established. The united mind determines the relationship between visual qualias of both sub units (like a person would compare the feeling in both her hands). Then from the memory of t the entire being retells the puzzle using the available qualia, so that he visualizes what has to be solved in both of its subunits. Then both brains are disconnected.

During the phase that follows after the first disconnection e attempts to solve the phenomenal puzzle on its own. All of the sensory stimuli to e are carefully controlled to prevent any form of leakage of the solution. e is allowed to use visual aids such as computer programs that help him manipulate his experience with great freedom.

At the same time, one needs to carefully control the mental state of t. The particular sensory input t receives is less important than guaranteeing that t does not make the sort of cognitive moves that would lead to an answer to the puzzle. For instance, distractions are great ways of doing this.

If the puzzle has been ‘standardized’ to be solved within a given range of time (its ecological difficulty has been assessed widely) one waits that amount and then reconnect t’s and e’s brain.

In that second period of union, the united entity assesses e’s solution to the phenomenal puzzle. If it has been solved, then t will be able to conclude that e is conscious even when they are disconnected. For e to have that certainty the roles will have to be reversed.

The puzzle itself

What are the axis of phenomenal color? Draw a map of color that separates it into phenomenally continuous colors at the same distance in terms of subjective difference.
