The current study investigates individual differences that predict situation awareness (SA) in professional pilots. The aim of the study is twofold: to examine the roles of divided attention, inhibition, working memory, and expertise in predicting SA, and to demonstrate the relative contributions of these individual differences to online (Situation Awareness Present Method, SPAM) and offline (Situation Awareness Global Assessment Technique, SAGAT) SA measures. Thirty-six professional pilots completed a challenging flight scenario in a full-flight simulator. Divided attention, inhibition, working memory span, and expertise were measured using choice reaction time with dichotic listening, Stroop, and Automated Operation Span tasks, and flight hours in a full-flight simulator, respectively. Results indicated that offline and online SA measure were not correlated, supporting their concurrent use to obtain a comprehensive measure of SA. Offline SA scores were best predicted by working memory and level of expertise, while online SA scores were predicted by expertise, divided attention and inhibition. Results are discussed focusing on both theoretical contributions for defining and measuring SA and applications. Findings have implications for operators of critical domains and their interactions with automated systems, in which SA is crucial for performance and safety.

Effect of goal orientation and different human computer interaction modalities on users’ engagement
Fal, Mehmetcan; Acartürk, Cengiz; Department of Cognitive Sciences (2016)
The purpose of this study is to investigate the effects of goal orientation and alternative human computer interaction modalities on user engagement. Performance-oriented and learning- oriented individuals exhibit motivational differences. Learning-oriented individuals focus on progress and mastery, whereas performance-oriented individuals focus on ability. Twenty-five participants participated in the study. They were asked to accomplish the same task with three alternative modalities of interaction, namely...
Effects of 6 weeks psychological skill training on team cohesion, self-confidence & anxiety : a case of youth basketball players
Miçooğulları, Okan Bülent; Kirazcı, Sadettin; Aşçı, F. Hülya; Department of Physical Education and Sports (2013)
The purpose of this study was to examine the impact of six weeks psychological skills training program (PST) based on cognitive-behavioral conceptual framework on the team cohesion, confidence, and anxiety of an intact team. Participants consisted of two teams of 36 male youth basketball players. The PST program consisted of team building, goal setting, relaxation, imagery, self-talk, pep-talk, converting thoughts, autogenic training, and progressive relaxation techniques. For the quantitative part of the s...
Effects of 6 Weeks Psychological Skill Training on Team Cohesion Self confidence Anxiety A Case of Youth Basketball Players
MİÇOOĞULLARI, BÜLENT OKAN; Kirazcı, Sadettin (2016-01-01)
The purpose of this study was to examine the impact of a six-week psychological skill training (PST) program that is based on a cognitive-behavioral conceptual framework on team cohesion, confidence, and anxiety of an intact team. Thirty-six male basketball players, 19 athletes for the experimental group and 17 athletes for the control group, aged between 15-16 years old voluntarily participated in this study. For the quantitative part of the study, the Group Environment Questionnaire, Trait Sport-Confidenc...
A systematic study of probabilistic aggregation strategies in swarm robotic systems
Soysal, Onur; Şahin, Erol; Department of Computer Engineering (2005)
In this study, a systematic analysis of probabilistic aggregation strategies in swarm robotic systems is presented. A generic aggregation behavior is proposed as a combination of four basic behaviors: obstacle avoidance, approach, repel, and wait. The latter three basic behaviors are combined using a three-state finite state machine with two probabilistic transitions among them. Two different metrics were used to compare performance of strategies. Through systematic experiments, how the aggregation performa...
Effects of culture on computer-supported international collaborations
Swigger, K; Alpaslan, Ferda Nur; Brazile, R; Monticino, M (Elsevier BV, 2004-03-01)
This paper discusses results of a case study from an on-going project to investigate how cultural factors, as identified by the Cultural Perspectives Questionnaire (CPQ), affect the performance of distributed collaborative learning teams. The results indicate that a team's cultural composition is a significant predictor of its performance on programming projects. Cultural attributes most strongly correlated to group performance included those related to attitudes about organizational hierarchy, organization...
