概括
评估性调节包括学习对刺激的情绪反应. 这项研究发现,虽然学习到的情绪反应可以泛化,但它们的减少 (灭绝) 和返回 (恢复) 并不能始终泛化到类似的刺激.
科学领域:

背景情况:
- 评估性条件化 (EC) 表明中性刺激如何通过与无条件刺激 (US) 的关联获得情感价值.
- 有条件的情绪反应可以概括到同一类别内的刺激.
- 灭绝和恢复是影响学习情感关联的关键过程,但它们的概括性不太了解.
研究的目的:
- 调查灭绝和恢复过程在评估条件化中对类别成员的概括性.
- 为了确定在条件化过程中使用多个样本是否会增强灭绝和恢复的概括性.
- 检查明确和隐含评估的概括,以及美国的预期.
主要方法:
- 在三个实验中采用了评估性调节范式.
- 参与者经历了获取,灭绝和恢复阶段,并与类型示例一起进行.
- 泛化刺激 (GS) 用于评估学习转移.
- 在实验3中使用了明确和隐含的措施 (情感启动任务).
- 无条件刺激 (美国) 预期也被监控.
主要成果:
- 在所有实验中,在获取过程中概括的评估.
- 当使用多个样本时,观察到灭绝期间评估的概括性 (实验2).
- 显式/隐式评价的灭绝和恢复都没有在实验中一致概括.
- 在所有实验中,美国预期的获取和灭绝是普遍的.

结论:
- 有部分证据表明,评价性概括发生在灭绝过程中,而不是恢复.

Generalization, Discrimination, and Extinction
459
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Principles of Classical Conditioning
511
Classical conditioning, as described by Ivan Pavlov, is a foundational concept in associative learning, where a neutral stimulus becomes capable of eliciting a conditioned response through association with an unconditioned stimulus. The process of acquisition, where this learning occurs, and the subsequent phenomena of contiguity, contingency, generalization, discrimination, extinction, and spontaneous recovery are crucial for a comprehensive understanding of classical conditioning.

Real-World Application of Classical Conditioning
531
Classical conditioning not only includes the initial pairing of stimuli but also extends to more complex forms, such as higher-order conditioning. Higher-order conditioning involves creating associations beyond the primary conditioned stimulus, resulting in a chain of conditioned responses.
Higher-order, or second-order, conditioning occurs when a neutral stimulus becomes associated with an already established conditioned stimulus through repeated pairings. For instance, if a dog has been...

Classical Conditioning in Daily Life
660
Classical conditioning, a fundamental principle of associative learning, explains various phenomena observed in daily life, such as fear development, the placebo effect, taste aversion, and drug habituation. These applications demonstrate the profound impact of associative learning on human behavior and physiological responses.
John B. Watson and Rosalie Rayner famously demonstrated the development of fear through classical conditioning in their experiment with Little Albert. They paired the...

Associative Learning
308
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

Classical Conditioning
457
Associative learning, a core principle in behavioral psychology, involves forming connections between events and facilitating learned responses. This concept is vividly illustrated by classical conditioning, a process extensively studied by the Russian physiologist Ivan Pavlov. Pavlov's pioneering research on dogs' digestive systems led to the discovery that behaviors can be learned through association, laying the groundwork for classical conditioning.
