认知灵活性对于适应行为至关重要,随着年龄的增长而下降. 年长的成年人在逆转任务中扎,对后果和阶级形成的敏感性降低,影响他们适应不断变化的环境需求的能力.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 老年学是一门学科.
背景情况:
- 认知灵活性是一种执行功能,涉及到调整行为以适应环境变化.
- 这一功能往往会随着年龄的增长而下降,影响日常生活和决策.
- 简单的歧视逆转任务评估认知灵活性及其组成部分.
研究的目的:
- 评估不同年龄组的认知灵活性及其组成过程.
- 调查与年龄相关的对后果的敏感性,学习集和概念形成的差异.
- 检查中年成人在认知灵活性任务上的表现.
主要方法:
- 在四个年龄组中,对100名参与者进行了一项简单的反向歧视任务.
- 参与者学会了三种视觉歧视,其次是三种刺激功能的逆转.
- 每个逆转阶段都必须满足性能标准.
主要成果:
- 年长的成年人更有可能未能达到逆转标准,这表明对后果的敏感性降低和阶级形成缺陷.
- 成功的老年人学习速度较慢,并在以后的反转中表现出较少的阶级形成.
- 所有符合标准的参与者都表现出学习集的形成,不论年龄.
结论:
- 衰老与认知灵活性的下降有关,特别是对后果和阶级形成的敏感性.
- 虽然老年人表现出缺陷,但在满足绩效标准时,学习集的形成在各个年龄段保持完整.
- 这项研究强调了与年龄相关的执行职能变化以及逆转任务在衰老研究中的实用性.

Generalization, Discrimination, and Extinction
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...
