Llu\u00eds Fuentemilla, investigador de l\u2019IDIBELL i la UB, va parlar sobre la mem\u00f2ria a la Biblioteca de Bellvitge el passat 20 de novembre. Aquesta xerrada s’emmarca a les activitats de la Setmana de la Ci\u00e8ncia.<\/p>\n
\u201cQu\u00e8 \u00e9s la mem\u00f2ria? \u00c9s alguna cosa tangible o no? Per qu\u00e8 ens recordem d\u2019algunes coses i no d\u2019altres? Parlarem de coses en relaci\u00f3 a la constituci\u00f3 de la mem\u00f2ria\u201d, va introduir el Dr. Fuentemilla. Durant la xerrada es va fer un exercici per veure la capacitat memor\u00edstica dels assistents i, a l’intentar memoritzar una relaci\u00f3 de paraules, es va demostrar que pens\u00e0vem haver escoltat paraules que no hav\u00edem escoltat: \u00e9s la falsa mem\u00f2ria.<\/p>\n
En lloc de plantejar els l\u00edmits de la mem\u00f2ria, l\u2019investigador va definir la mem\u00f2ria com un sistema que compr\u00e8n una codificaci\u00f3, \u00e9s a dir el processament del missatge, per una altra banda, l\u2019emmagatzematge, que implica un record permanent de la informaci\u00f3 codificada, i per \u00faltim, la recuperaci\u00f3 de la informaci\u00f3. \u00c9s pot fer una analogia entre la ment i un ordinador, per\u00f2 no funciona aix\u00ed. Hi ha circumst\u00e0ncies que canvia aix\u00f2: la nostra ment no funciona aix\u00ed. No ens recordem de certes coses perqu\u00e8 no codifiquem b\u00e9 la informaci\u00f3. \u00c9s el t\u00edpic cas d\u2019on he posat les claus o la moto. O tamb\u00e9 perqu\u00e8 no la sabem recuperar de forma correcta.<\/p>\n
\u201cLa mem\u00f2ria est\u00e0 estructurada en diverses funcions\u201d, va dir l\u2019investigador. La mem\u00f2ria pot ser mem\u00f2ria declarativa, que es divideix en mem\u00f2ria epis\u00f2dica, que fa refer\u00e8ncia a coses que ens ha passat, la mem\u00f2ria sem\u00e0ntica, que t\u00e9 a veure a coses que no ens ha passat, com qui \u00e9s el president dels EUA, i la mem\u00f2ria de treball, que serveix per la mem\u00f2ria a curt termini. Tamb\u00e9 est\u00e0 la mem\u00f2ria no-declarativa, com la que fem servir quan anem en bici o condu\u00efm, \u00e9s una mem\u00f2ria basada en l\u2019aprenentatge.<\/p>\n
\u201cEl nostre cervell ens ha donat una capacitat per imaginar altres situacions que no hem viscut, amb molt poques dades i poca informaci\u00f3. Prenem decisions sense tenir una informaci\u00f3 completa de la situaci\u00f3. Podem anar cap al futur, amb la informaci\u00f3 que tenim del passat\u201d, coment\u00e0 el Dr. Fuentemilla.<\/p>\n
\u201cSom conscients de tot all\u00f2 que recordem?\u201d<\/strong> <\/p>\n <\/strong> No recordem en un moment on estan les claus i un altre moment et ve al cap on estaven. Com passa aix\u00f2? Aquesta informaci\u00f3 sempre ha estat al nostre cervell. Una cosa \u00e9s el que tenim a la mem\u00f2ria i un altre, el que som capa\u00e7os de recordar. Tenim una capacitat enorme per recordar coses.<\/p>\n \u201cEls nostres ulls no ens enganyen. Hem fet recerca seguint els moviments oculars. Encara que una persona no se\u2019n recordi, els ulls van cap al lloc on estava la informaci\u00f3 que es cerca\u201d, el Dr. Fuentemilla avan\u00e7\u00e0 resultats d\u2019estudis recents.<\/p>\n Hi ha aspectes de la son que s\u00f3n b\u00e0siques per memoritzar. \u201cDurant el dia acumulem informaci\u00f3, i per la nit, quan dormim, el nostre proc\u00e9s d\u2019aprenentatge finalitza i arrela la informaci\u00f3 que ens interessa. El son afavoreix aquest proc\u00e9s\u201d, va finalitzar l\u2019investigador.<\/p>\n","protected":false},"excerpt":{"rendered":" Llu\u00eds Fuentemilla, investigador de l\u2019IDIBELL i la UB, va parlar sobre la mem\u00f2ria a la Biblioteca de Bellvitge el passat 20 de novembre.
