Personal Identity01:25

Personal Identity

358
Personal identity is the deeply felt sense of self that individuals cultivate over time, intricately woven from intrinsic qualities they consider essential to their existence—qualities such as morality, intelligence, and friendliness. These attributes serve as vital internal benchmarks, guiding individuals in evaluating whether their actions resonate with their true selves.When personal identity takes center stage in one's life, individuals often emphasize their distinctiveness,...

Trigonometric Identities II01:28

Trigonometric Identities II

415
Double-angle and half-angle trigonometric identities are derived from the fundamental sum and difference formulas and serve as essential tools for simplifying expressions, solving equations, and evaluating integrals. These identities reduce the complexity of trigonometric functions by relating functions of a multiple or fractional angle to functions of a single angle. Their applications extend across mathematics, physics, and engineering, particularly in Fourier analysis, wave mechanics, and...

State Space Representation01:27

State Space Representation

558
The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.
Consider an RLC circuit, a...

Control Volume and System Representations01:16

Control Volume and System Representations

1.5K
Two key frameworks are employed to analyze mass, energy, and momentum transfer: the control volume approach and the system approach. These frameworks offer different perspectives, depending on whether the focus is on a specific region in space (control volume approach) or a defined mass of fluid (system approach).
The control volume approach considers a stationary region in space through which fluid flows. This region is bounded by a control surface.  For instance, in the case of water...

Graphical Representation of Inequalities01:28

Graphical Representation of Inequalities

200
The graph of the equation where y equals x squared forms a curve known as a parabola. This curve acts as a boundary in the coordinate plane, dividing it into distinct regions based on the relative position of points.When the equality sign in the equation is replaced with an inequality—such as greater than, less than, greater than or equal to, or less than or equal to—the graphical representation changes from a single curve into a broader shaded area that signifies the set of all...

Social Identity01:29

Social Identity

268
Social identity constitutes a significant aspect of an individual’s self-concept, shaped by membership in various social groups, including gender, nationality, ethnicity, sexual orientation, and political affiliation. Individuals associate specific traits with particular social groups, leading to internalization of these traits. For example, musicians are often perceived as creative, while women are frequently associated with nurturing tendencies. Once individuals identify with a...

科学分野:

  • 認知心理学
  • 神経科学
  • 視覚知覚

背景:

  • ワーキングメモリ（WM）表現に一致するディストラクタによる注意捕捉は、視覚探索を妨げる。
  • リソース仮説は、リソース配分が注意捕捉に影響すると予測するが、先行研究では一貫性のない結果が示されている。
  • 注意捕捉は、記憶に基づく注意ガイダンスの準備中の注意バイアスに由来する可能性がある。

研究 の 目的:

  • 注意捕捉とワーキングメモリ（WM）リソース配分の関係を調査すること。
  • WMリソース分布の操作が注意捕捉の大きさに影響するかどうかを判断すること。

主な方法:

  • 2つの実験では、注意捕捉パラダイムと連続遅延推定課題を組み合わせた。
  • 実験1では、記憶アイテムの数（1つ対2つ）を操作した。
  • 実験2では、2つの記憶アイテムを用いて、レトロキュー課題によりリソース配分を操作した。

主要な成果:

  • 実験1では、アイテムが1つの場合のWM精度向上は、注意捕捉の大きさを変化させなかった。
  • 実験2では、キューイングされた記憶アイテムは精度が高かったが、注意捕捉の大きさに影響しなかった。
  • WMリソースの配分は、注意捕捉効果の大きさに有意な影響を与えなかった。

結論:

  • ワーキングメモリ（WM）リソースの分布は、注意捕捉効果の大きさに影響しない。
  • 注意捕捉は、記憶に基づく注意ガイダンスの準備中の注意バイアスに由来する可能性がある。
