Field: Human Factors
Source: Frontiers in Neuroscience (2019)
Method: Quasi-experimental intervention study with EEG measurements and neuropsychological assessments.
Evidence: Strong effect

Engaging in music or visual art training can lead to lasting improvements in auditory processing and temporary enhancements in visual inhibitory control in older adults, suggesting a neuroplastic response to creative engagement. This human factors research insight is drawn from a 2019 study published in Frontiers in Neuroscience. Using Quasi-experimental intervention study with eeg measurements and neuropsychological assessments., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Consider integrating sensory-rich and creative engagement opportunities into product design and user experience to promote cognitive vitality in aging populations.

Music and Visual Art Training Enhance Auditory Processing and Visual Inhibition in Older Adults

Frontiers in Neuroscience · 2019

Key Findings

01Music and visual art training led to persistent enhancements in auditory evoked responses to piano tones, lasting up to 3 months post-training.
02Both training programs modulated visual processing during a GoNoGo task, but these effects were short-lived and not present at the 3-month follow-up.
03Visual art training showed greater changes in visual evoked response amplitude distribution compared to music or control groups.
04Music training was associated with greater changes in inhibitory control over right frontal scalp areas compared to visual art training.

Application

Design takeaway

Consider integrating sensory-rich and creative engagement opportunities into product design and user experience to promote cognitive vitality in aging populations.

How to apply

Develop interactive digital experiences or physical products that encourage musical or artistic creation and consumption, specifically targeting older users to support their cognitive well-being.

Project actions

01When designing for older adults, consider how sensory and creative activities can be integrated to support cognitive health.
02Explore how different types of creative engagement might have unique impacts on specific cognitive functions.

Method & Evidence

AimTo investigate the effects of music and visual art training on neuroelectric brain activity and cognitive performance in older adults, and to determine the persistence of these effects.

MethodQuasi-experimental intervention study with EEG measurements and neuropsychological assessments.

ProcedureParticipants were assigned to either a music training group, a visual art training group, or a non-active control group. High-density EEG was recorded during auditory oddball tasks (piano tones, vowels) and a visual GoNoGo task before, immediately after, and three months after the 3-month training period. Neuropsychological assessments were also administered at these time points.

ContextCognitive training and neuroplasticity in older adults.

Variables

IV["Type of training (music, visual art, control)"]

DV["Auditory evoked responses (piano tones, vowels)","Visual evoked responses (GoNoGo task)","Neuropsychological assessment scores"]

CV["Age of participants","Duration of training","Time points of assessment (pre, post, follow-up)"]

Strengths & Limitations

Strengths

+Longitudinal design with a 3-month follow-up to assess persistence of effects.
+Use of objective neurophysiological measures (EEG) alongside behavioral assessments.

Limitations

The study's findings on psychometric measures were not significant, indicating that while brain activity changes, overall cognitive scores might not reflect these changes immediately or broadly.

Reliability & validity

The use of standardized EEG paradigms and neuropsychological tests contributes to the reliability and validity of the findings. The inclusion of a control group helps establish causality.

Think critically

To what extent can these observed neuroplastic changes be generalized to other forms of creative expression or to different age groups?

Design Principles

"Creative engagement fosters neuroplasticity, enhancing sensory processing and executive functions."

This research highlights how specific creative activities can positively impact cognitive functions relevant to daily life, such as perception and response inhibition. For designers, understanding these effects can inform the creation of products, environments, and experiences that support cognitive health and well-being in aging populations.

What This Means for Your Design

Doing music or art can make your brain better at hearing and temporarily better at focusing on visual things, especially for older people.

How to use in your project

1.Use this study to justify the inclusion of sensory or creative elements in a design project aimed at improving cognitive function in a specific user group, like older adults.
