概括
韦伯定律是感官知觉的基础,在某些条件下被发现被违反了. 提出的选择电路机制解释了韦伯分数中的粘附和轻微偏差.
科学领域:
- 神经科学是一个神经科学.
- 心理物理学的精神物理.
- 感官感知是一种感官感知.
背景情况:
- 韦伯定律认为,刚刚可察觉的差异与刺激强度成比例.
- 这个原理,概括为比率原理,可以在各种感觉模式中观察到.
- 然而,实验数据显示有系统的违规行为,特别是刺激强度和低强度的韦伯分数之间的凸关系.
研究的目的:
- 通过假设的选择电路模型,研究韦伯定律的机械基础.
- 确定这个模型是否能够解释维伯定律的遵守和观察到的违反.
- 调和理论预测与实验发现的感官歧视.
主要方法:
- 使用了具有全球抑制的选择电路的理论模型.
- 从线性编码的刺激强度和选择概率模拟了韦伯定律的出现.
- 分析模型输出,以确定导致遵守和违反法律的条件.
主要成果:
- 选择电路机制成功地重现了韦伯定律的出现.
- 同一个机制也解释了轻微的违规行为,法律未能为高概率的正确反应.
- 模型预测与韦伯分数凸度的实验观测定性一致.
结论:
- 假设的选择电路机制为韦伯定律及其观察到的违规行为提供了统一的解释.
- 该模型强调了选择概率在感官歧视中的作用.
- 需要进一步的研究来解释低强度范围内的偏差的大小.

Conformity
44.9K
Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group.

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Cause and Effect
10.8K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Attribution Theory
12.9K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

Deindividuation
26.2K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Law of Effect
1.3K
B.F. Skinner, a prominent figure in behavioral psychology, introduced operant conditioning by emphasizing the role of consequences in shaping behavior. This theory builds upon the law of effect proposed by Edward Thorndike, which posits that behaviors followed by satisfying outcomes are likely to be repeated. In contrast, those followed by unsatisfying outcomes are less likely to recur.
