Ethics in Research

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Area of Science:

Neuroscience
Biomedical Engineering
Cognitive Science

Background:

Functional near-infrared spectroscopy (fNIRS) methodology and analysis tools are expanding, necessitating clear guidelines for study design.
Existing guidelines focus on preprocessing, analysis, and reporting, but guidance for the crucial planning stage is lacking.
Study preregistration offers a method for transparently documenting protocols, enhancing study verification, understanding, and reproducibility.

Purpose of the Study:

To develop a comprehensive guide for the design and analysis steps in functional near-infrared spectroscopy (fNIRS) studies.
To provide a specialized preregistration template tailored for fNIRS research.

Main Methods:

The guide focuses on fNIRS-specific requirements, using continuous-wave (CW) fNIRS studies in humans as examples.
It systematically covers key methodological and analysis aspects for study design.
Includes general sections applicable to all fNIRS studies, with a detailed focus on sample size planning.

Main Results:

A step-by-step walkthrough of essential methodological and analysis considerations for fNIRS study design.
Specific guidance for CW, task-based fNIRS studies, alongside generalizable principles.
In-depth elaboration on sample size planning for robust study design.

Conclusions:

Introduces open science tools to the fNIRS community, enhancing study planning transparency.
Provides researchers with key design aspects and specification recommendations.
The guide and template can be used for preregistering fNIRS studies or as a tool for transparent study design.
