Summary
Online crowdsourcing enables larger, more diverse studies in cognitive and human systems neuroscience. This approach enhances reproducibility and generalizability of behavioral research findings beyond traditional lab settings.
Area of Science:
- Cognitive Neuroscience
- Human Systems Neuroscience
- Behavioral Science
Background:
- Traditional neuroscience research relies on in-person lab studies, often limited by small sample sizes.
- Small sample sizes lead to underpowering and reduced reproducibility in behavioral research.
- Crowdsourcing is a proven method for increasing sample sizes in fields like neuroeconomics and social sciences.
Purpose of the Study:
- To review the emerging use of online crowdsourcing in cognitive and human systems neuroscience.
- To highlight the potential of crowdsourcing for increasing sample sizes and improving research generalizability.
- To discuss the benefits and limitations of online data collection for neuroscience.
Main Methods:
- Review of current literature on online crowdsourcing in neuroscience.
- Examination of methodological advancements enabling complex online cognitive, perceptual, and motor tasks.
- Analysis of data tracking capabilities (keyboard, mouse, eye gaze) in online studies.
Main Results:
- Online crowdsourcing allows for large-scale studies with diverse participant pools.
- It enables testing hypotheses in real-world environments, enhancing generalizability.
- Methodological advances permit complex behavioral tasks to be conducted online.
Conclusions:
- Online crowdsourcing offers a viable solution to limitations of in-laboratory studies, especially during crises like the COVID-19 pandemic.
- This approach can significantly broaden the scope and strengthen the conclusions of neuroscience research.
- Addressing current limitations will further solidify crowdsourcing's role in advancing cognitive and human systems neuroscience.

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...

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...
