Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

371
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Information Processing Approach

213
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

236
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.

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Introduction to Cognitive Psychology

1.8K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

High-Level and Low-Level Awareness

425
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Area of Science:

  • Cognitive Neuroscience
  • Neuropsychology

Background:

  • Older adults with typical memory changes implicitly learn and utilize irrelevant information.
  • Implicit learning's role in amnestic mild cognitive impairment (aMCI) remains less understood.

Purpose of the Study:

  • To investigate whether implicit processes benefit cognitive abilities in individuals with aMCI.
  • To compare implicit learning and its effects in aMCI patients versus healthy older adults.

Main Methods:

  • Participants completed a picture judgment task with distracting words.
  • Implicit memory for distractors was assessed using a word-fragment completion task.
  • Twenty-two aMCI patients and 22 matched controls were studied.

Main Results:

  • Both groups exhibited a priming effect, successfully completing word fragments from previously seen words.
  • The aMCI group demonstrated significantly higher scores on the word-fragment completion task compared to controls.
  • This indicates enhanced implicit memory processing in the aMCI group.

Conclusions:

  • Individuals with aMCI show enhanced implicit memory.
  • Implicitly acquired information can improve performance on explicit memory tasks in aMCI.
  • Findings suggest potential for interventions leveraging implicit learning in aMCI populations.
