Factors Affecting Perception

2.9K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

科学领域:

  • 认知心理学 认知心理学
  • 神经科学是一个神经科学.
  • 多感官处理 处理多感官

背景情况:

  • 视觉注意力是由语义信息指导的.
  • 人们对语义如何在多感官环境中塑造注意力知之甚少.
  • 与任务无关的声音可以促进对匹配目标的视觉搜索.

研究的目的:

  • 调查语义信息是否会影响视听环境中的注意力,而不仅仅是直接匹配.
  • 为了确定声音图像语义相关性是否会影响视觉搜索速度.
  • 检查当语义信息与任务无关时,这种效应是否还存在.

主要方法:

  • 参与者搜索目标图像,而声音和图像之间的语义相关性则有系统地变化.
  • 两个后续实验使用直角的加博尔歧视任务来评估任务相关性.
  • 行为搜索速度是主要指标.

主要成果:

  • 视觉搜索速度与声音图像语义相关性进行缩放;目标与更多相关的声音被发现得更快.
  • 这种语义缩放效应甚至在声音与任务无关时也存在.
  • 语义知识强有力的引导视听注意力,无论任务相关性或直接匹配.

结论:

  • 语义知识在很大程度上引导了视听的注意力.
  • 一个强大的认知机制处理跨感官模式的语义,以影响注意力分配.
  • 这种机制甚至适用于与任务无关的刺激,并且超出了直接的感官匹配.
