Working Memory01:24

Working Memory

993
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...

Storage01:23

Storage

430
A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.1K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Information Processing Approach01:30

Information Processing Approach

641
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Visual Agnosia01:12

Visual Agnosia

1.4K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

1.3K
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

科学分野:

  • 神経科学
  • 認知心理学
  • 発達心理学

背景:

  • 作動記憶を含む実行機能は、自発的な眼球運動の制御に不可欠である。
  • 注意欠陥・多動性障害（ADHD）のような神経発達症は、実行機能の障害と関連している。

研究 の 目的:

  • ADHDのある子供と青年、および神経発達症の対照群における反衝動眼球運動（AS）と記憶誘導性衝動眼球運動（MGS）を調査すること。
  • これらの群におけるASとMGSのパフォーマンスの関係を調べること。

主な方法:

  • EyeLink 1000+アイトラッカーを使用した眼球運動テスト。
  • ADHDのある参加者65名と神経発達症の対照群74名（9.1〜17.3歳）における反衝動眼球運動（AS）と記憶誘導性衝動眼球運動（MGS）の記録。

主要な成果:

  • ADHDのある参加者は、空間精度が低下したMGSの精度が低かった。
  • ADHD群ではASの精度が低下する傾向が見られたが、空間精度は正常だった。
  • 対照群とADHD群の両方で、ASとMGSの空間精度の間に有意な相関が見られた。

結論:

  • MGSに不可欠な作動記憶における空間情報の貯蔵は、ADHDにおいて損なわれているようである。
  • ASに必要な空間情報の処理は、ADHDにおいて大部分が損なわれていない。
  • 貯蔵障害にもかかわらず、ADHDにおける作動記憶の貯蔵と処理の関係は損なわれていない。
