System of Memory01:23

System of Memory

7.4K
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

902
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

697
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

587
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

522
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

16.9K
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:

  • Cognitive Psychology
  • Neuroscience
  • Memory Research

Background:

  • High-level executive control is typically considered a conscious process.
  • Emerging evidence suggests unconscious executive functions may exist.

Purpose of the Study:

  • To investigate if unconscious executive control impacts memory retrieval and forgetting.
  • To determine if subliminal cues can manipulate memory recall and suppression.

Main Methods:

  • Participants learned word associations and were cued to recall or forget them consciously.
  • These cues were then presented subliminally during a separate task.
  • Memory recall was assessed after exposure to both conscious and subliminal cues.

Main Results:

  • Both conscious and subliminal cues significantly influenced memory retrieval.
  • Unconscious instructions to forget reduced memory recall compared to baseline and recall cues.
  • Memory suppression occurred outside of participants' awareness.

Conclusions:

  • Executive control, including memory suppression, can operate unconsciously.
  • Subliminal executive control can manipulate specific memories without awareness.
  • Findings challenge traditional views of executive functions as solely conscious processes.
