Resumen
Internet actúa como memoria externa, haciendo que la información sea fácilmente accesible. Esperar el acceso futuro a la información en línea reduce el recuerdo personal, pero mejora la memoria de dónde encontrarla.
Área de la Ciencia:
- Psicología Cognitiva Psicología cognitiva.
- Interacción hombre-computadora Interacción hombre-computadora.
- Ciencias de la información Ciencias de la información.
Sus antecedentes:
- Internet y los motores de búsqueda han revolucionado el acceso a la información.
- Las herramientas digitales facilitan la fácil recuperación de información, reduciendo la carga cognitiva.
Objetivo del estudio:
- Investigar cómo Internet influye en la memoria humana y el recuerdo de la información.
- Explorar el concepto de Internet como fuente de memoria externa o transactiva.
Principales métodos:
- Se llevaron a cabo cuatro estudios para examinar la recuperación de la memoria en condiciones de acceso esperado a Internet.
- Se midió el recuerdo de la información y su fuente por parte de los participantes.
Principales resultados:
- Las preguntas difíciles impulsan a los individuos a pensar en las computadoras y los motores de búsqueda.
- Anticipar el acceso futuro a la información en línea conduce a una disminución en el recuerdo de la información en sí.
- El recuerdo se mejora para la ubicación o la fuente de información en lugar del contenido de la información.
Conclusiones:
- Internet funciona como un sistema de memoria externa muy importante.
- Nuestra dependencia de las fuentes de información digital cambia la forma en que almacenamos y recuperamos el conocimiento.

01:08The Availability Heuristic
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):
01:16Interference and Decay
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

01:30Impact of Schemas
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...
01:21Forgetting
Forgetting is an intrinsic aspect of human memory, characterized by the gradual loss or inaccessibility of information over time. Hermann Ebbinghaus, a pioneering psychologist, extensively studied this phenomenon and formulated the forgetting curve. This curve illustrates that memory loss occurs rapidly immediately after learning and then decelerates over time. Several mechanisms contribute to forgetting, including encoding failure, storage decay, retrieval failure, and interference.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
01:19Understanding Memory
Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...
