概括
强烈的认知任务会损害自我控制,导致表现问题. 这项研究揭示了与认知疲劳和高认知需求任务后减少响应抑制有关的独特的神经活动模式.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
背景情况:
- 长时间参与认知要求高的任务会导致认知疲劳.
- 这种疲劳通常表现为自我控制效率下降和性能不稳定,特别是在需要控制冲动的任务后.
研究的目的:
- 研究高认知需求 (HCD) 任务的延长实践对反应抑制和潜在的电脑电图 (EEG) 活动的影响.
- 将这些效应与低认知需求 (LCD) 任务引起的效应进行比较.
主要方法:
- 25名健康的成年人在长时间练习HCD或LCD任务后执行了Go-No Go任务.

Working Memory
127
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
95
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Role of Cerebellum and Prefrontal Cortex in Memory
349
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Language and Cognition
318
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
