Cognitive Development During Adulthood

Cognitive Development During Adulthood

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,...

Summary

This study found that a 4-week cognitive training program with neurofeedback (CT-NF) using ABC games improved memory and cognitive function in healthy older adults. Both training and control groups showed gains in processing speed and executive function.

Background:

Cognitive decline is a concern in aging populations.
Cognitive training and neurofeedback are potential interventions.
App-based cognitive training offers accessible solutions.

Purpose of the Study:

To evaluate the efficacy of a 4-week app-based cognitive training with neurofeedback (CT-NF) program.
To compare an ABC games intervention group with a Tetris control group.
To assess changes in cognitive functions and cortical brain activity.

Main Methods:

86 healthy adults (54-84 years) were randomized into treatment (ABC games) or control (Tetris) groups.
Participants underwent a 4-week CT-NF intervention.
Cognitive assessments and functional near-infrared spectroscopy (fNIRS) were used pre- and post-intervention.

Main Results:

The ABC group showed significant improvements in memory (MEM), verbal memory (VBM), and composite cognitive function.
Both groups improved in processing speed (PS) and executive function (EF).
Cortical brain activity strength correlated with cognitive and game performance.

Conclusions:

CT-NF, particularly with ABC exercises, enhances cognitive functions including MEM, VBM, PS, and EF in healthy older adults.
The findings support the use of targeted cognitive training for cognitive enhancement.
Neurofeedback may play a role in mediating cognitive improvements.
