概括
在认知双重任务 (TUGdt) 测试时评估轮值持续时间 (TUG) 可能有助于区分认知能力. 在TUGdt中更长的转表明有可能识别认知障碍风险.
科学领域:
- 神经学 神经学
- 老年学是指老年学的学科.
- 生物医学工程 生物医学工程
背景情况:
- 认知障碍,包括痴呆症和轻度认知障碍,影响全球数百万人.
- 早期发现认知衰退对于及时干预和管理至关重要.
- 定时并进行 (TUG) 测试是一种广泛使用的功能移动性评估.
研究的目的:
- 调查TUG测试参数,特别是双重任务期间的转动时间和步态参数,是否可以区分具有不同认知能力的个体.
- 探索TUG和TUG与认知双重任务 (TUGdt) 在识别认知障碍方面的实用性.
主要方法:
- 参与者 (N=334) 被分为痴呆症,轻度认知障碍,主观认知障碍和对照组.
- 试验对象进行了TUG测试和TUGdt (动物命名,反向月份诵读).
- 转时间和步骤参数 (前进/后退步行) 使用后勤回归和标准化赔率比率进行了分析.
主要成果:
- 在认知功能较低的群体中,在TUGdt期间观察到更长的转换时间.
- 一个较小的趋势表明,在认知群体中,相对于身体高度的步骤长度存在差异.
- 后勤回归模型发现了 TUGdt 转换时间和认知状态之间的显著关联.
结论:

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Human behavior is intricately shaped by social influences that arise from interactions with others in diverse contexts. These influences not only mold beliefs and attitudes but also drive the regulation of behaviors through both direct communication and observational learning. The study of these processes falls within the domain of social psychology, which seeks to understand how individuals are affected by and affect those around them.Mechanisms of Social InfluenceDirect social influence...

01:24Generalization, Discrimination, and Extinction
1.4K
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...

The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...

Relating Reaction Mechanisms
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
