- 心理生理学 心理生理学
背景情况:
- 奖励积极性 (RewP) 是反映奖励处理的事件相关潜力,由收益和避免不良结果引起.
- 痛苦不容忍 (DI) 是心理病理学中不适应性回避策略的一个关键风险因素.
- 有限的研究已经探索了差异性奖励反应和DI之间的联系.
研究的目的:
- 调查在涉及货币收益/损失和避免厌恶结果的任务期间,苦难不容忍 (DI) 和奖励处理之间的关联.
- 检查DI是否与避免负面刺激相关的奖励反应有关.
主要方法:

Positive and Negative Feedback Loops
25.3K
Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires maintaining an internal dynamic equilibrium:

Root Loci for Positive-Feedback Systems
351
The Hartley oscillator is a positive feedback system that sustains oscillations by feeding the output back to the input in phase, thereby reinforcing the signal. Positive feedback systems can be viewed as negative feedback systems with inverted feedback signals. In these systems, the root locus encompasses all points on the s-plane where the angle of the system transfer function equals 360 degrees.
The construction rules for the root locus in positive feedback systems are similar to those in...

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!

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance
686
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Feedback Loops

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Conditioned Taste Aversion
609
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...
