Toward an understanding of macrocognition in teams: predicting processes in complex collaborative contexts.

Objective: This article presents a model for predicting complex collaborative processes as they arise in one-of-a-kind problem-solving situations to predict performance outcomes. The goal is to outline a set of key processes and their interrelationship and to describe how these can be used to predict collaboration processes embedded within problem-solving contexts.

Background: Teams are increasingly called upon to address complex problem-solving tasks in novel situations.

Do familiar teammates request and accept more backup? Transactive memory in air traffic control.

Objective: The present study investigated factors that explain when and why different groups of teammates are more likely to request and accept backup from one another when needed in an environment characterized by extreme time pressure and severe consequences of error: commercial air traffic control (ATC).

Background: Transactive memory theory states that teammates develop consensus regarding the distribution of their relative expertise as well as confidence in that expertise over time and that this facilitates coordination processes. The present study investigated whether this theory could help to explain between-team differences in requesting and accepting backup when needed.

Investigating linear and interactive effects of shared mental models on safety and efficiency in a field setting.

Linkages between 2 types of shared mental models (SMMs)--that is, positional-goal interdependencies and cue-strategy associations--and effectiveness in an air traffic control environment were investigated. Two types of SMMs were expected to contribute uniquely, as well as interact, to predict tower safety and efficiency. Using SMM data from 306 air traffic controllers, and corresponding archival efficiency and safety measures for 47 airports, the authors found no significant linear relationships between SMMs and either outcome measure.
