Area of Science:

Cognitive Psychology
Human Computer Interaction
Neuroscience

Background:

Online data collection offers advantages in participant access and reduced experiment duration.
Traditional lab-based studies provide controlled environments for cognitive research.

Purpose of the Study:

To compare the efficacy of online versus lab-based data collection for spatial memory tasks.
To assess the impact of unsupervised online samples on data quality and variability.

Main Methods:

Participants completed a spatial memory task involving object location estimation after viewpoint shifts.
Data were collected from both a controlled laboratory setting and an unsupervised online sample.

Main Results:

Spatial memory performance showed similar patterns across both lab and online data.
Online data exhibited approximately 10% greater variability (larger standard errors) compared to lab data.

Conclusions:

Spatial memory studies utilizing static images can be successfully conducted online with unsupervised participants.
To achieve comparable statistical power, online sample sizes should be increased by 25% to mitigate higher data variability.
