まとめ
複数の個人を観察している場合でも、他の人が動いているボールを遮断できるかどうかを正確に判断できる。この遮断可能性の知覚は、ボールとパドルの動きからの視覚的な手がかりに依存している。
科学分野:
- 認知心理学;知覚科学;ヒューマンコンピュータインタラクション
背景:
- 以前の研究では、個人が自分自身と他の1人のための遮断可能性を知覚できることが示されています。;現在の研究では、複数の他者のための遮断可能性の知覚を調査しています。
研究 の 目的:
- 観察者が複数の俳優のための遮断可能性のアフォーダンスを知覚できるかどうかを判断すること。;他者の行動の遮断可能性を判断するために使用される視覚情報を特定すること。
主な方法:
- 参加者(俳優)は、制約された条件下でパドルを使用してボールを遮断しようとしました。;観察者は、最終的な結果が隠された俳優のパドルの運動学の記録を視聴しました。;観察者は、2項強制選択(2AFC)法を使用して、俳優がボールを遮断できるかどうかを判断しました。
主要な成果:
- 観察者は、俳優の遮断可能性を判断する際に72%の精度を達成しました。;観察者の精度は、俳優としての事前経験に影響されませんでした。;遮断可能性を判断するための情報は、展開中のボールとパドルの運動学に存在します。
結論:
- 個人は、複数の他者のための遮断可能性のアフォーダンスを確実に知覚できます。;視覚ディスプレイの運動学的情報は、他者の行動能力を判断するのに十分です。;遮断可能性の知覚は、タスクにおける個人的な経験とは独立した、堅牢な能力です。

Actor-Observer Effect
446
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

Collisions in Multiple Dimensions: Introduction
7.1K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

Collisions in Multiple Dimensions: Problem Solving
5.6K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Social Traps
27.0K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Bystander Effect
10.4K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
