The claim is that the brain processes colour more quickly than it processes words.

The Stroop effect shows it is probably not as simple as that. For readers proficient in a language, word recognition becomes so quick, it interferes with colour recognition.

Okay okay okay Alex. I hear the dedicated people who have read this far…

What about gradient colour text tech? Which helps guide vision to the next line (return sweeps). Surely there is nothing problematic with that??

Wellllll… ❌ish

This was shown in the trailing mask paradigm.

As readers read “garden path” sentences (start out ambiguously e.g. “The desert trains… [1]…boys to be men [2]…are hot and dusty), a trail of x’s replaces the previously read word.

The boundary paradigm uses an invisible boundary next to a “preview” or “target” word. The preview word is a non-word; the target word is a normal one.

In the non-word case, as the reader saccades across the invisible boundary, the computer changes it to the normal word (readers unaware).

In natural reading, the loss is even smaller. This is likely because of parafoveal preview benefit. The second problem with RSVP.

Despite parafoveal vision being blurrier, it has been shown that the brain can preprocess upcoming words in a sentence…

Okay, so how about we turn to tech and remove the saccades completely?

What about using rapid-serial-visual-presentation (RSVP) apps, that will display one word at a time?

Sorry to disappoint, but again, probs a No ❌

For many reasons…

In the “gaze contingent moving window paradigm” experiments, readers looked at a line of text.

However, most of the text was obscured as “x’s” apart from a window digitally made around a reader’s fixation point (tracked using a camera).

As the reader moved their eyes, so did the window…

The angular region in which your vision is clearest is only 1 degree each side of the fixation (this area is approx. equivalent to holding your thumb out at arm’s length).

The visual acuity drops off moderately over next 4 degrees (parafovea), then dramatically after this (periphery).

Cone neural receptors sharply decrease in density as you enter the parafovea (ring surrounding centre).

Rod neural receptors, are sensitive only to brightness and are concentrated in the parafovea, decreasing slowly the further out you go.

How do we read then?

To state the obvious… one word at a time (mostly).

Your eyes will “fixate” on a point in one word, then move quickly in a jump (saccade) to the next word (if the word is long, your eyes will fix on a location further down the same word).

Finally, take everything I've just said with a pinch of salt.

Social Science examines the most complex systems (interacting neural networks) with almost none of the tools available to the hard sciences.

I'll leave you with this infographic with an accidental placeholder no one removed.
