概括
声音的感知强度受到环境的影响. 可预测的声音将听觉处理转移到平均声音水平,解释了感官衰减和增强.
科学领域:
- 听觉感知是一种听觉感知.
- 精神声学是一种精神声学.
- 认知神经科学是一种认知神经科学.
背景情况:
- 自生成的行为通常会导致感官衰减,使事件看起来不那么强烈.
- 然而,一些研究报告说,对自我产生的声音进行感官增强,从而产生了一个悖论.
- 现有的理论,就像前模型一样,努力解释这两种现象的一致性.
研究的目的:
- 调查感官减弱和增强是否是适应对平均声音统计的适应性反应.
- 测试关于即将到来的声音的预测是否会将听觉处理转移到平均声音背景.
- 挑战传感衰减的占主导地位的前模型解释.
主要方法:
- 330名人类参与者对自己产生的声音 (40-80 dB) 的强度进行了评分.
- 通过创建 predominantly 大声 (80 dB) 或安静 (40 dB) 声音的背景来操纵听力处理.
- 在可预测和不可预测的声音条件下测量感知噪音.
主要成果:
- 感知到的声音强度显示向平均声音水平回归,不管声音是自制的还是被动听到的.
- 声音的可预测性,而不是自我生成,是推动感知变化的关键因素.
- 在适应的环境中,很少出现的安静音调在响亮的环境中被增强,而响亮的音调在安静的环境中被减弱.
结论:
- 感觉衰减和增强可以通过回归到平均音量水平来解释.
- 可预测性,而不是自我生成,是这些感知转变的主要驱动力.
- 这些发现挑战了前性模型,并提出了对听觉感知适应的替代解释.

Regression Toward the Mean
6.8K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Factors Affecting Perception
2.6K
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.

Fundamental Attribution Error
13.7K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Actor-Observer Effect
332
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...

Attribution
262
In social interactions, individuals frequently seek to understand the motivations and causes behind others' behaviors. This fundamental aspect of social perception, known as attribution, plays a crucial role in shaping interpersonal relationships and guiding future actions. Attribution refers to the cognitive process through which people infer the reasons behind others' behaviors, allowing them to assess character traits, intentions, and situational influences.Attribution Theory and Its...

Perception
999
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...
