Cognitivism

1.7K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

244
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

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...

Cognitive Learning

516
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Observational Learning01:12

Observational Learning

310
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Introduction to Cognitive Psychology01:20

Introduction to Cognitive Psychology

796
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

科学分野:

  • 計算神経科学
  • コンピュータビジョン
  • 認知心理学

背景:

  • シーンのコンテキストは 視覚的知覚とオブジェクト認識に 大きく影響します 特に困難な状況では
  • オブジェクト選択脳領域を調節するシーン情報を含むトップダウンメカニズムが示唆されているが,完全に理解されていません.

研究 の 目的:

  • オブジェクト認識のための生物学的にインスピレーションを受けたコンテキストベースの計算モデル (CBM) を導入する.
  • シーンの文脈をオブジェクト認識に統合する明示的なフィードバックメカニズムの役割を調査する.
  • CBMのパフォーマンスを標準的なフィードフォワードモデルと人間の認識と比較する.

主な方法:

  • 2つの経路を持つコンテキストベースの計算モデル (CBM) を開発:オブジェクトの特徴のためのObject_CNNとシーンの文脈のためのPlace_CNN.
  • 視覚の劣化や遮断を伴うオブジェクト認識のタスクに関するCBMとAlexNet (標準的なフィードフォワードモデル) を比較した.
  • 人間のオブジェクト認識とCBMとAlexNetのパフォーマンスを比較する行動実験を行いました.

主要な成果:

  • CBMはオブジェクト認識においてAlexNetを大幅に上回り,劣化した入力に対する文脈フィードバックの利点を示しました.
  • 人間の参加者は,特に高レベルの閉塞で,一致した文脈から控えめな利益を示しました.
  • 人間による認識は文脈なくとも強固であり,グローバルな形状処理と局所的な繰り返しのプロセスの支配的な役割を示唆しています.

結論:

  • 文脈的なフィードバックは,オブジェクト認識のためのコンピューティングモデルのパフォーマンスを向上させることができます.
  • 人間の視覚的知覚は,固有のオブジェクト処理と局所的な繰り返しのメカニズムに大きく依存し,異なる戦略を採用しています.
  • 将来のモデルは,人間の視覚的回復力をよりよく模倣するために,局所的な繰り返しのプロセスと文脈に敏感なフィードバックを統合する必要があります.
