Natural and Artificial Concepts

In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint Vincent in...

Background:

Dementia significantly impairs executive function, impacting daily living and independence.
Existing cognitive assistive technologies often overlook executive function support for daily tasks.
A novel AI-powered cognitive prosthesis was developed to address this gap, focusing on real-time guidance for daily activities.

Purpose of the Study:

To evaluate an AI-based cognitive prosthesis for its effectiveness in improving task completion time and executive function in individuals with mild dementia.
To assess the impact of real-time AI guidance on daily task performance and independence in a mild dementia population.

Main Methods:

A pilot study was conducted with 12 individuals with mild dementia and 7 healthy controls.
Participants completed a gamified egg-boiling task with and without AI guidance, assessed via a custom Daily Task Completion Test and a modified Executive Function Performance Test (EFPT).
Demographic, clinical data, and System Usability Scale (SUS) were collected; AI system performance metrics (precision, recall) were also analyzed.

Main Results:

The AI prosthesis significantly reduced task completion time by 31.7% and improved EFPT scores by 76.5% in the mild dementia group (P=.03 and P=.005, respectively).
No significant changes were observed in the healthy control group.
The AI system demonstrated high usability (mean SUS score 80.53) and strong performance (precision 0.93, recall 0.94).

Conclusions:

This pilot study suggests that an AI-based cognitive prosthesis can effectively enhance executive function and task performance in individuals with mild dementia.
The findings support the feasibility of using AI for real-time guidance to promote independence in daily activities.
Further longitudinal studies are recommended to confirm sustained benefits and explore the system's potential as a digital therapeutic.
