Stereotype Content Model02:16

Stereotype Content Model

14.9K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Concepts and Prototypes01:24

Concepts and Prototypes

220
The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Natural and Artificial Concepts01:24

Natural and Artificial Concepts

264
In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Explicit Memories01:27

Explicit Memories

193
Explicit memories, also known as declarative memories, are consciously remembered, recalled, and reported. Studying for a chemistry exam involves material that will become part of explicit memory. There are two types of explicit memory: episodic and semantic.
Episodic memory contains information about personally experienced events and is reported as a story. An example of episodic memory is recalling a birthday celebration. This type of memory includes the what, where, and when of an event, as...

Segregation in Fresh Concrete01:16

Segregation in Fresh Concrete

233
Segregation in fresh concrete is a phenomenon where the components of the concrete mix separate, leading to uneven distribution and compromised structural integrity. This separation typically occurs when concrete is subjected to excessive horizontal movement within forms, or when it is dropped from considerable heights or forced through narrow, winding paths. As a result, heavier coarse aggregate particles settle at the bottom, while lighter, finer materials such as cement and water rise to the...

科学分野:

  • 認知心理学
  • 心理言語学
  • 神経科学

背景:

  • 具体性の効果は,抽象的な概念 (例えば信念) よりも,具体的な概念 (例えばバナナ) の処理が速いことを示しています.
  • 以前の研究によると 心理言語学的な変数は 具体性の効果に影響を及ぼしたり 逆転させたりします
  • 辞典的・意味論的処理におけるカテゴリ的特異性の役割は,まだ十分に研究されていない.

研究 の 目的:

  • 辞書と意味論のアクセスに対するカテゴリ的特異性の影響を調査する.
  • カテゴリ的な特異性が確立された具体性の効果を調節するかどうかを判断する.
  • 概念的抽象化に影響を与える要因の理解を広げること.

主な方法:

  • 参加者の評価は,コンセプトの具体性と特異性のために収集されました.
  • 単語認識の速度と精度を評価した.
  • 意味に基づいた判断の速度と精度を評価した.

主要な成果:

  • 抽象的な概念よりも具体的な概念の処理上の優位性を確認しました (具体性効果).
  • 一般的な概念よりも特定の概念の重要な処理利点 (特異性効果) を特定しました.
  • 具体性と特異性との間に有意な相互作用は見られなかった.

結論:

  • 概念の具体性とカテゴリ的特異性の両方が独立して語彙的および意味論的処理を強化します.
  • カテゴリ的特異性は,コンクリート性と共に概念的処理に影響を与える重要な変数です.
  • 発見は概念的抽象化とテキスト処理モデルのより微妙な理解に貢献します.
