Where this meets science

Wake Me Up is titled as a science of language. The most powerful class I ever took was Linguistics 101, and when I taught from memory I sometimes taught the lecture summary as if it were the finding. The practices on the other pages still stand. What changes here is the strength of the claim.

Quotes under “In my own words” stay as I spoke them. They are a record of the talk, not a citation.

In that talk I said that if language is not developed by age five or six, a person forever stands apart, and never wires the brain for semantics and for complex logic. I was remembering a lecture on children kept from language, and a simplified critical period.

A first language does have a sensitive period, and it is strongest for grammar. Eric Lenneberg, in Biological Foundations of Language (1967), put the outer edge nearer puberty than age five. Rachel Mayberry’s studies of deaf adults are the clearest evidence since: people who met a fully accessible language late — signed or spoken — remain weaker on complex syntax, and the later the start, the larger the cost. Early language, in either form, protects later learning (Mayberry & Lock, 2003; Mayberry & Kluender, 2018). The decline is graded across childhood.

Sound contrasts narrow earliest. By about the first birthday, infants stop discriminating many speech sounds that are not in the language around them (Werker & Tees, 1984).

Word meanings stay open much longer than grammar. Genie, kept from language until about thirteen, later learned a large vocabulary; what stayed severely limited was syntax (Curtiss and colleagues). A girl known in the literature as Isabelle, found around age six, acquired language to a typical level within a couple of years (Davis, 1947). That is the counterexample to a forever-lost cutoff at five or six.

Missing language in early childhood is a real and often lasting cost, especially for grammar and for the kinds of thought grammar supports. It is a cost. It is not a verdict that someone is less human. I will not say that again.

I said that without language a person cannot model the world. Infants already model objects, causes, and places before they have sentences (Spelke’s core-knowledge work). Other animals do too. Language adds a particular model: one that can order events, talk about what is not in the room, and be lived as a story.

Philip Johnson-Laird’s mental-models work describes people reasoning by building structured models from sentences. Jennie Pyers and Ann Senghas (2009), watching Nicaraguan Sign Language grow, found that adults whose early language lacked words for mental states failed false-belief tasks, and improved as that vocabulary appeared. Years of social life had not done that job alone. That is the honest version of “sequence, story, plans, meaning” on Your voice creates your reality.

A second language nudges what is easy to notice and easy to say. It does not imprison thought. That is the modest form of the old Sapir–Whorf idea (thinking-for-speaking; the modern attention studies), not the strong one I sometimes implied.

“The model is not you,” on When it hurts, is the sentence I want held when the story breaks. It is a teaching. It is not a clinical result that taking words apart removes pain.

They say the first time you teach a child the word cardinal is the last time they see the bird — after that they go to the lexicon, the reference image, the clip art. I have not found a published source for that saying. I still use it, because the direction is real and the absolute is not.

Gary Lupyan’s label-feedback work: when people named a particular chair “chair,” they were worse later at recognizing that chair (Journal of Experimental Psychology: General, 2008). The label highlights what is typical of the category and compresses what is idiosyncratic. Hearing a color word warps discrimination the same way: between-category differences get easier, two typical shades of the named color get slightly harder (Lupyan & Forder, and the 2012 label-feedback paper).

Jonathan Schooler and Tonya Engstler-Schooler (1990) found that describing a face in words impaired recognizing that face. The visual memory was overshadowed. It was not erased. When people had less time to decide, the original look came back.

The other half matters. A finer lexicon can help you see more. Experts shift from the basic word (“bird”) to the specific one (“cardinal,” then the marks that separate this cardinal), and discrimination improves (Tanaka & Taylor, 1991). One word covering many birds blurs. Many precise words sharpen. So the practice — ask what the word was about to replace — matches the studies. “The last time they see it” does not.

Gün Semin and Klaus Fiedler’s linguistic category model (1988) orders person-language from concrete to abstract: a plain action, an interpreted action, a state, an adjective. Adjectives such as stubborn are the most abstract. They imply a stable trait, say little about the situation, and are hard to verify. “He interrupted me twice” can be answered. “He’s stubborn” gets defended. That is the spell on Judgment is in the word, and it lands on the speaker’s model.

Contradictory self-talk does confuse the person who hears it, including you. I will not say a subconscious recorder files “I’m so stupid” as fact. A bright affirmation you do not believe can make a low mood worse (Wood, Perunovic, & Lee, 2009), which is why Speak yourself into existence refuses fake positive speech.

Clarity as a human ability buried under childhood filters, and the sense that you then know almost at once what someone feels and why: my experience. Perception and emotion-reading generally grow sharper with development, and people overestimate how well they read others. The minute before the word is still the practice. “Clair” is not a finding.

On Presence, not performance, my voice deepening as I became more decisive is my life, not a result about pitch. Calling NLP a discipline for faking authentic expression is my characterization of a conversation I was in. What I can say more carefully: reviews of NLP’s specific techniques have not found reliable effects (Witkowski, 2010). The breaths before speaking are still the practice.

A trigger as judgment and emotion already stuck to a word is a way to practice. Clinical triggers are wider than a fused word. This page is not medical advice, and neither is the guide.

“There is nothing pure in this material universe” — no pure black, no pure white — I do treat as physical honesty. It lives on the Physical layer, and in the talk.
