Caught by LOOKING at the live page on 2026-07-30, right after\n   the template was switched to canvas.\n\n   Everything is scoped to `.bp-adv`, so nothing here can reach the rest of\n   bioprofile.com, and core blocks are styled BY ELEMENT so a heading, a\n   paragraph, a quote, a list, an image or a button inserted by hand inside the\n   advertorial comes out on-design with no class to remember.\n\n   Jesse's design feedback, 2026-07-29 23:38, point by point:\n   1. the light green and the dark green are the preferred colours; grey may be\n      used but the page must NOT open grey;\n   2. more colour and variation across sections, e.g. a colour block on the left\n      or the right side of a section, without overdesign;\n   3. ONE H1, plain text on white; everything else H2 or H3; an H2 may carry its\n      own background colour so the page can be read from the headings alone; an\n      H3 keeps its section background and gets a bigger font size;\n   4. reuse the results page design feel;\n   5. Written by \/ Verified by, the placeholder blocks and noindex stay.\n\n   COLOUR PROVENANCE. Not one hex is invented.\n   - #b7cb32  LIGHT GREEN, brand manual \"colours rejuvenation protocol\"\n              (R183 G203 B51). Same value as --bp-lime in\n              brands\/bioprofile\/brand\/tokens.md.\n   - #006b62  DARK GREEN, brand manual, nourish the cells (R0 G107 B98).\n   - #005859  brand manual primary teal, the value the brand is built on.\n   - #228a62  brand manual, challenge the body (R34 G138 B98).\n   - #7ca64c  brand manual, calm the mind (R124 G166 B76).\n   - #dbd4cd  brand manual \"additional color\", the warm neutral.\n   - #B7CB3329 is the brand token --bp-lime-soft (light green at 16 percent).\n   - the gradients are the brand token layer's own, copied verbatim.\n\n   SPECIFICITY NOTE. Elementor's global kit emits `.elementor-kit-6 h2` style\n   rules at (0,1,1). Element rules below are written `.bp-adv h2`, also (0,1,1),\n   and win on source order because this sheet is inline in the body while the\n   kit is a <link> in the head. Component rules that MUST NOT lose carry two\n   classes, e.g. `.bp-adv .wp-block-button__link`.\n\n   LAYOUT NOTE. Vertical rhythm uses `margin-block` and never the `margin`\n   shorthand, so the measure rule `.bp-adv-sec > * { margin-inline: auto }` can\n   centre a block without being outranked by its own element rule.\n   =========================================================================== *\/\n\n.bp-adv {\n  --bp-ink: #212527;\n  --bp-teal: #005859;\n  --bp-forest: #006B62;\n  --bp-emerald: #228A62;\n  --bp-olive: #7CA64C;\n  --bp-lime: #B7CB33;\n  --bp-lime-soft: #B7CB3329;\n  --bp-sand: #DBD4CB;\n  --bp-white: #FFFFFF;\n  --bp-foot: #6b6b6b;\n  --bp-grad-dark: linear-gradient(237deg, rgba(0,88,89,0.00) 62.94%, #005859 100%), linear-gradient(90deg, rgba(34,138,98,0.00) 40%, #228A62 100%), #006B62;\n  --bp-grad-lime: linear-gradient(110deg, rgba(183,203,51,0.00) 36.06%, rgba(183,203,51,0.25) 97.65%), #FFFFFF;\n  --bp-font: 'Poppins','Segoe UI',Arial,sans-serif;\n  --bp-fs-h1: 44px; --bp-fs-h2: 31px; --bp-fs-h3: 24px; --bp-fs-pre: 15px;\n  --bp-fs-body: 17px; --bp-fs-small: 14px; --bp-fs-foot: 13px; --bp-fs-btn: 17px;\n  --bp-lh-body: 1.75;\n  --bp-s-1: 4px; --bp-s-2: 8px; --bp-s-3: 12px; --bp-s-4: 16px;\n  --bp-s-5: 24px; --bp-s-6: 32px; --bp-s-7: 44px; --bp-s-8: 72px;\n  --bp-measure: 760px; --bp-side: 40px;\n  --bp-radius-photo: 16px; --bp-radius-btn: 10px; --bp-radius-card: 20px;\n  --bp-shadow: 0 10px 30px rgba(0,88,89,0.10);\n  font-family: var(--bp-font);\n  font-size: var(--bp-fs-body);\n  line-height: var(--bp-lh-body);\n  color: var(--bp-ink);\n  background: var(--bp-white);\n  -webkit-font-smoothing: antialiased;\n}\n.bp-adv, .bp-adv * { box-sizing: border-box; }\n.bp-adv p, .bp-adv li, .bp-adv h1, .bp-adv h2, .bp-adv h3, .bp-adv blockquote,\n.bp-adv a, .bp-adv cite, .bp-adv span { overflow-wrap: break-word; min-width: 0; }\n\n\/* THE TOGGLE.

Jesse 2026-08-24 18:35. *\/\n\/* WHY THIS RULE EXISTS AND WHY IT IS FIRST. The theme ships\n   `body, html { overflow-x: hidden }` as an inline head style. overflow-x:hidden\n   forces the OTHER axis from visible to auto, so html and body both become\n   scroll containers, and a sticky element sticks to its nearest scrollport: the\n   bar was pinned to a box as tall as the whole document, which never scrolls.\n   Measured on this preview 2026-08-24: position:sticky applied, computed top 0,\n   and the bar still left the screen at y=-600 after a 600px scroll. `clip`\n   clips exactly the same overflow WITHOUT creating a scroll container, so the\n   viewport is the scrollport again and the bar sticks. Equal specificity to the\n   theme rule and later in document order, which is what wins it; a browser too\n   old for `clip` keeps `hidden` and a bar that scrolls away, which is the old\n   page and never a broken one. *\/\nhtml,body{overflow-x:clip}\n.bp-adv-sitehead.wp-block-group{position:sticky;top:0;z-index:120;background:#fff;\n  border-bottom:1px solid #e6ece9;padding:12px 24px;margin:0}\n.bp-adv-sitehead.wp-block-group>*{margin-block:0}\n.bp-adv-sitehead.is-stuck{box-shadow:0 2px 10px rgba(0,88,89,0.08)}\n.bp-adv-sitehead .bp-adv-sitehead-row{max-width:1120px;margin:0 auto;display:flex;\n  align-items:center;justify-content:space-between;gap:12px}\n.bp-adv-sitehead .bp-adv-sitehead-row>*{margin-block:0}\n.bp-adv-sitehead .bp-adv-sitehead-row .bp-adv-sitehead-logo{margin:0;max-width:none;\n  flex:0 0 auto;line-height:0}\na.bp-adv-sitehead-cta{display:inline-flex;align-items:center;justify-content:center;\n  flex:0 0 auto;min-height:40px;padding:0 22px;border-radius:999px;\n  background:#005859;color:#fff;font-family:'Poppins','Segoe UI',Arial,sans-serif;\n  font-size:15px;font-weight:600;line-height:1.2;white-space:nowrap;\n  text-decoration:none;transition:background 250ms ease}\na.bp-adv-sitehead-cta:hover,a.bp-adv-sitehead-cta:focus{background:#7CA64C;color:#fff}\na.bp-adv-sitehead-cta:focus-visible{outline:2px solid #005859;outline-offset:2px}\n\/* T188: the text link to the scans index, beside the pill. margin-left:auto takes\n   the row's free space, so link and pill sit together at the right edge and the\n   logo stays where it is.

Es la memoria que usas mientras est\u00e1s haciendo algo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">C\u00f3mo: Cowan puso uno al lado de otro los experimentos de capacidad de d\u00e9cadas de investigaci\u00f3n y se fij\u00f3 en cuatro tipos de situaciones en las que ese l\u00edmite se hace visible: cuando llega tanta informaci\u00f3n a la vez que no se puede agrupar, cuando se bloquean la agrupaci\u00f3n y la repetici\u00f3n mental, cuando el rendimiento se hunde en un punto concreto, y donde ese mismo l\u00edmite influye de forma indirecta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los hallazgos: en esas condiciones, la capacidad fiable ronda de media las cuatro unidades. Los investigadores llaman a esa unidad \"chunk\": un bloque de informaci\u00f3n que retienes como una sola cosa. Otros ya hab\u00edan llegado antes a una cifra de tres a cinco, y Cowan sostiene que ese l\u00edmite m\u00e1s bajo es el real. Seg\u00fan Cowan, el n\u00famero siete de 1956 era m\u00e1s una estimaci\u00f3n aproximada y un recurso ret\u00f3rico que un l\u00edmite real.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dicho en plata: retienes unas cuatro cosas a la vez.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Y reconoce con honestidad qu\u00e9 es este trabajo. Cowan no hizo ning\u00fan experimento propio. Su art\u00edculo se public\u00f3 junto con comentarios abiertos de colegas del campo, un formato de publicaci\u00f3n que parte de la r\u00e9plica. El cuatro es una media obtenida en tareas de laboratorio acotadas, no una propiedad fija de tu cabeza ni una medida de tu memoria en la vida diaria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suma lo que tu martes quiere cargar sobre esas cuatro: la reuni\u00f3n, el mensaje sin contestar, recoger a los ni\u00f1os y aquello por lo que entraste en la cocina.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hay algo m\u00e1s.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En 2003, <strong>Trends in Cognitive Sciences<\/strong> public\u00f3 un art\u00edculo de revisi\u00f3n de Stephen Monsell sobre los cambios de tarea.\u00b2<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que se investig\u00f3: qu\u00e9 ocurre cuando pasas de una tarea a otra.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">C\u00f3mo: Monsell resumi\u00f3 experimentos en los que las personas ten\u00edan que cambiar una y otra vez entre un peque\u00f1o n\u00famero de tareas sencillas, de modo que se puede calcular el coste del propio cambio. No recogi\u00f3 datos nuevos por su cuenta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los hallazgos: justo despu\u00e9s de un cambio, las personas son claramente m\u00e1s lentas y suelen cometer m\u00e1s errores. Los investigadores lo llaman el \"coste del cambio\".<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En parte de los experimentos, las personas sab\u00edan de antemano que iba a llegar el cambio. Esa es la comparaci\u00f3n que no tiene el primer estudio. Entonces los costes del cambio se reducen. No desaparecen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Monsell se\u00f1ala dos causas: la tarea anterior sigue actuando en tu cabeza, a veces un momento y a veces mucho m\u00e1s, y volver a ajustar tu atenci\u00f3n a la siguiente tarea lleva tiempo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que este estudio no puede decir: trata de tareas de laboratorio sencillas de 2003, sin notificaciones, sin correo y sin tel\u00e9fono. No aparecen segundos ni porcentajes. Quien te diga cu\u00e1ntos minutos cuesta una interrupci\u00f3n, saca esa cifra de otra parte.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Y luego est\u00e1 el estado en el que haces todo esto. Tambi\u00e9n se ha medido.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En 2026, <strong>Medicine and Science in Sports and Exercise<\/strong> public\u00f3 un estudio cruzado aleatorizado con 117 personas adultas.\u00b3<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que se investig\u00f3: qu\u00e9 efecto tiene pensar con esfuerzo durante mucho tiempo en el tiempo de reacci\u00f3n en una prueba GoNoGo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">C\u00f3mo: 117 participantes, 57 mujeres incluidas, con una edad media de 32 a\u00f1os. Todo el mundo hizo las dos sesiones. Una vez, 45 minutos de una tarea Stroop ajustada al nivel de cada participante. La otra, un documental elegido por cada participante, de la misma duraci\u00f3n. Despu\u00e9s, siempre la misma prueba GoNoGo de seis minutos, en la que unas veces tienes que responder y otras contener la respuesta.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los hallazgos: tras la tarea de Stroop, el tiempo de reacci\u00f3n en la prueba GoNoGo fue peor que tras el documental (P &lt; 0,001).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Este dise\u00f1o permite algo que los dos anteriores no permiten: las mismas personas hicieron las dos sesiones, as\u00ed que comparas a cada persona consigo misma. Lo que aparece entonces se llama \"fatiga mental\": no es un estado de \u00e1nimo, sino algo que se refleja en las mediciones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo que no puede decir: ese cansancio se provoc\u00f3 con una tarea de laboratorio; no se prob\u00f3 una jornada real llena de pantallas. El efecto medido es peque\u00f1o (\u03b7p2 = 0,07). No se describe ning\u00fan cegamiento. Y no se prob\u00f3 ning\u00fan alimento ni ning\u00fan suplemento.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pon los tres hallazgos uno al lado del otro.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n\n<li>Retienes unas cuatro cosas a la vez.<\/li>\n\n\n<li>Cada cambio te cuesta velocidad y precisi\u00f3n.<\/li>\n\n\n<li>Tras 45 minutos de pensar con esfuerzo, quienes participaron respondieron m\u00e1s despacio en la prueba GoNoGo.<\/li>\n\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Cuarenta no es una medici\u00f3n.
