Development of an Objective Behavioral Assay of Cohesion to Enhance Composition, Task Performance, and Psychosocial Adaptation in Long-Term Work Groups (Work_Groups)
Scientific Name: Homo sapiens Species: Human
The overarching goal of this study was to generate experimentally-derived insights on how crew composition and trait-like cooperative motivation predict task cohesion, social cohesion, and biopsychosocial adaptation in long-term work groups through systematic ground-based research and development of a simple, rapid, and objective behavioral assay of implicit propensity toward cooperation, productivity, and fairness.
This study had the following specific aims:
- Investigate effects of group composition on voluntary cooperation.
- Investigate effects of crew composition on performance, task cohesion, social cohesion, and psychosocial adaptation in long-term work groups.
- Develop next-generation Task Performance Task (TPT) software.
- Extended long-term research of group cohesion, team performance, and biopsychosocial adaptation to several space analog environments; the Human Exploration Research Analog (HERA) facility, NASA's Extreme Environment Mission Operations (NEEMO) laboratory, and the investigator's laboratory using Planetary Exploration Simulation (PES).

Investigators conducted ground-based experiments to systematically investigate the effects of group composition (gender and personality) on voluntary cooperative propensity in three-person teams. They also assessed the predictive validity of pre-mission TPT "social personality profiles" and the effects of group composition on performance, task cohesion, social cohesion, and biopsychosocial adaptation in mixed-gender "crews" participating in a long-term simulated space exploration task. In addition, investigators also developed next-generation software to advance the technology beyond their current prototype used for proof-of-concept/validation research into a broadly applicable tool with cross-platform networking and connectivity, enhanced usability/human factors features, extensive parameter manipulation/flexibility to maximize sensitivity, and integrated data collection and processing capabilities.
Results indicate that the TPT/COHESION objective social behavioral assay approach is sensitive to team composition factors and temporal dynamics in both laboratory and field settings. Laboratory experiments reveal a potential risk of decreased cooperation and reduced cooperative resilience in majority female teams and teams with whose members are all high in conscientiousness. The TPT/COHESION tool quantifies "individual differences" in social behavioral processes over time at both the person and team levels, which correlate with subjective ratings of team cohesion. A single pre-mission TPT/COHESION session can predict several objective in-mission team performance outcomes.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit.
The Human Research Program (HRP) investigates and mitigates the highest risks to human health
and performance, providing essential countermeasures and technologies for human space exploration.
Risks include physiological and performance effects from hazards such as radiation, altered gravity,
and hostile environments, as well as unique challenges in medical support, human factors,
and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify
the approach and research activities planned to address these risks, which are assigned to specific
Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
The Human Research Roadmap is located at: https://humanresearchroadmap.nasa.gov/
