System of Memory01:23

System of Memory

7.3K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working Memory01:24

Working Memory

839
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Long-Term Memory01:18

Long-Term Memory

663
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

Traumatic Memory01:20

Traumatic Memory

563
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Repressed Memory01:16

Repressed Memory

506
Repressed memories are a psychological phenomenon where memories of traumatic events are unconsciously blocked from a person's awareness. This process occurs as a defense mechanism, protecting the mind from the emotional impact of distressing or painful experiences. For example, a person who has experienced childhood trauma may grow up with no conscious recollection of the event. In such cases, the memories are thought to be buried deep within the subconscious, inaccessible to the conscious...

Immunological Memory01:23

Immunological Memory

15.1K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Area of Science:

  • Biomedical Engineering
  • Computer Science
  • Gerontology

Background:

  • Internet of Things (IoT) sensors enable continuous, effortless monitoring for early disease detection.
  • Early disease detection via IoT can significantly improve patient quality of life through timely interventions.
  • Memory loss detection is crucial for managing cognitive decline and associated conditions.

Purpose of the Study:

  • To introduce a novel smart cupboard system for assessing user memory.
  • To detect potential memory loss by analyzing object-location recall within the cupboard.
  • To validate the smart cupboard's efficacy against established memory assessment tools.

Main Methods:

  • Development of a three-door smart cupboard equipped with sensors connected to a Raspberry Pi.
  • Implementation of a Python script to detect door openings and classify user interactions.
  • Assessment of the smart cupboard with 23 users, comparing results to face-name association and self-reported memory tests.

Main Results:

  • The smart cupboard successfully differentiated between successful and unsuccessful object retrieval attempts.
  • A significant correlation was found between the smart cupboard's memory measurements and validated memory tests.
  • The system demonstrated effectiveness in measuring user memory concerning object locations.

Conclusions:

  • The novel three-door smart cupboard is a viable tool for measuring user memory.
  • This IoT-based system shows promise for early detection of memory loss.
  • The smart cupboard offers a non-intrusive method for cognitive assessment in daily life.
