>> reading ... isn't about letter by letter, but about the impression of entire words

> This is a strangely popular myth

Praheps that starengly pouplar mtyh about rediang is gronuded in the nautre of cogitnive prcoesess.

I'm under the impression that I'm reading words from both ends with a rather diffuse emphasis on the middle, progressing from both ends towards the middle (maybe at times with a slightly stronger emphasis on the ending) and stopping, when sufficiently ensured, both by the gestalt and and from context. It's more like grabbing the words than reading them sequentially. This is also true for entire groups of words. Generally speaking, reading fluently is a different processing from spelling words out.

It's simplified but not a myth. This article from Science Alert explains it better than I do: https://www.sciencealert.com/word-jumble-meme-first-last-let...

This is false.
