概括
人类的习惯形成被研究使用一个双响应链任务. 延长训练导致习惯的发展,使得第一个反应对第二个反应的变化不敏感.
科学领域:
- 行为神经科学 行为神经科学
- 认知心理学 认知心理学
背景情况:
- 习惯在日常生活中起着至关重要的作用,并与诸如上之类的行为病理有关.
- 对老鼠的研究表明,习惯形成,以结果不敏感为特征,随着广泛的练习而发展.
研究的目的:
- 为了研究人类的习惯形成,使用双响应的歧视性行为链.
- 确定延长训练是否会降低第一反应 (R1) 对第二反应 (R2) 灭绝的敏感性.
主要方法:
- 鼠和人类参与者学会了两种反应链 (R1-R2),其中两种反应都需要加强.
- 在经过中度和长时间的训练后,评估了R1对R2灭绝的敏感性.
- 在R2灭绝之前,实验3专门训练人类在单个R1-R2链上.
主要成果:
- 在老鼠中,R1在中度但不延长训练后对R2灭绝敏感,表明习惯.
- 在人类中,在多个链上进行延长训练并没有降低R1对R2灭绝的敏感性.
- 然而,通过单一链和扩展训练,人类R1对R2的灭绝变得不敏感,这表明习惯形成.
结论:
- 习惯形成,以对结果变化的反应不敏感为特征,在特定的实验室条件下可以在人类身上证明.
- 这些发现与非人类研究一致,但强调了证明人类习惯的挑战.
- 这项研究有助于了解习惯形成背后的机制及其在成中的潜在作用.

Fixed Action Patterns
15.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Role of Shaping in Operant Conditioning
232
Shaping is a technique used in operant conditioning to train complex behaviors by rewarding successive approximations toward the target behavior. This method is necessary because organisms are unlikely to perform complex behaviors spontaneously. Instead, shaping breaks down the desired behavior into small, manageable steps.
The steps involved in shaping begin with reinforcing any response that resembles the desired behavior. For example, parents might praise a child for picking up one toy. As...

Timing and Consequences on Behavior
62
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Behaviorism
2.2K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Cognitive Learning
112
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Behavior Modification
113
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
