概括
当注意力转移时,视觉拥挤效应会改变. 闪的侧翼在注意力转移期间减少了拥挤,表明了注意力系统之间的协同作用,影响了视觉感知.
科学领域:
- 视觉感知 视觉感知 视觉感知
- 认知心理学 认知心理学
- 注意力研究研究注意力研究
背景情况:
- 视觉拥挤受到目标侧翼相似性和注意力固定时的间距的影响.
- 这些因素在注意力转移期间对拥挤的影响仍未得到充分研究.
研究的目的:
- 调查目标侧翼相似性和间距如何影响注意力转移期间的视觉拥挤.
- 探索外源和内源注意力线索在调节拥挤中的相互作用.
主要方法:
- 参与者看到了侧面的加博尔目标,呈现在固定的左和右边.
- 实验操作包括目标/侧翼闪,波长相似性和间距 (在Bouma的边界内/外).
- 通过中央快速串行视觉呈现 (RSVP) 线索来指导注意力转移.
主要成果:
- 目标闪提高了准确性;侧翼闪减少了拥挤,特别是在注意力转移期间,这表明外源/内源协同作用.
- 与目标相同的波长的侧翼造成了显著的人群拥挤,无论方向如何.
- 在注意力转移期间的拥挤效应在不同的目标侧翼间距 (在Bouma的边界内外) 中是一致的.
- 当注意力持续专注于目标时,Bouma的边界被重新建立起来.
结论:
- 视觉拥挤暂时扩大,当注意力转移时,它变得不那么有歧视性.
- 注意力动态显著调节视觉拥挤的特征和影响.

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

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.
