Los tres modelos de aprendizaje más conocidos —conductismo, cognitivismo y constructivismo— nos ofrecen distintas formas de entender cómo aprendemos. El conductismo, representado por Iván Pavlov, se enfoca en el cambio de comportamiento observable como resultado del estímulo y la respuesta; es muy útil en el desarrollo de hábitos, rutinas o cuando se busca reforzar conductas específicas. El cognitivismo, propuesto por Jean Piaget, plantea que el aprendizaje ocurre cuando procesamos, codificamos y reorganizamos internamente la información; este enfoque es ideal para mejorar la comprensión, la memoria y el pensamiento lógico. 🤓

Por último, el constructivismo, basado en las ideas de Lev Vygotsky, sostiene que aprendemos a partir de nuestras experiencias previas y de la interpretación que damos a la información; este modelo favorece un aprendizaje más profundo, significativo y personalizado, promoviendo la participación activa y el pensamiento crítico. Juntos, estos modelos nos ayudan a diseñar métodos educativos más eficaces según nuestras necesidades y contextos.👀

Scientists Find Brain Structure That's Twice the Normal Size in Depressed People:

Understanding how depression takes hold in the brain is crucial to preventing and treating it, and new research has uncovered a brain network that appears to be significantly larger in individuals with depression.

The frontostriatal salience network, a region associated with reward processing and filtering external stimuli, was found to be nearly twice its typical size in most people with depression.

This discovery, made by researchers at Weill Cornell Medicine, suggests that targeting this specific brain network could lead to more effective treatments for the condition.

Using precision functional mapping, a method offering a detailed look at individual brain layouts, the researchers analyzed brain scans from 57 individuals with depression and 37 healthy controls.

They found that the frontostriatal salience network had expanded, encroaching on areas typically controlled by other brain networks. This expansion was confirmed across larger datasets and remained stable over time, regardless of mood state. Importantly, the network expansion was also detected in children before they were diagnosed with depression, suggesting that it may serve as a risk factor for the disorder rather than a consequence of it.

While more research is needed, this discovery represents a significant step toward better understanding depression and developing targeted treatments.
