New Citations | Large Group Studies

BIOPAC provides software and hardware that allows research teams to study large group interactions. Here are a few notable studies using BIOPAC equipment for large group research focusing on participation and EDA data.

Participation is Key

Active participation in education is always thought to lead to better results. Using two groups of six students, TA’s led labs using Biopac Student Lab, one with a traditional approach and one with an active learning approach. Both groups were tested after to see who retained more information.

Majority Rule vs. Consensus Rule

Between majority rule and consensus rule, which system solves complex problems quicker and more practically? This study aimed to find out using groups of three, five, and seven participants and a MP36 to record galvanic skin response (GSR) while producing solutions using both ruling types. Which ruling system generated better results? Read the full study: Group decision-making: Consensus rule versus majority rule (Elizabeth Taylor, Kelsey Hewitt, Dr. Robert A. Reeves, Dr. Stephen H. Hobbs, W.F. Lawless)

Too Upset to Think

Could a person really be too emotionally upset to provide constructive solutions to social problems? By hooking up participants in large groups to a BIOPAC Data Acquisition System, researchers measured EDA responses in conjunction with verbal solutions given to see how emotional context and emotional arousal play a vital role in problem solving.

Chapman, Nathalie Lovasz, Kris Walters)

fNIRS Data Analysis

In this fNIRS training, you will see a typical analysis workflow for fNIRS data in experiments featuring both event-based and continuous stimulation. Learn about a powerful yet easy-to-use software package with both a graphical user interface and scripting capability (for automation).

What You Will Learn:
• Preparing data for analysis
• Signal conditioning, noise removal, and managing artifacts
• Best practices for visualizing recorded data
• Block analysis using event markers and/or time
• Further temporal and spatial processing of data, including cell-by-cell processing
• Automation of analysis procedures
• Performing common statistical comparisons (t-test, ANOVA)
• Spatial visualization
