Article Citation - WoS: 39Citation - Scopus: 49Effects of Working Memory, Attention, and Expertise on Pilots' Situation Awareness(Springer London Ltd, 2020) Cak, Serkan; Say, Bilge; Misirlisoy, MineThe 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.Article Citation - WoS: 5Citation - Scopus: 5Evaluation of an Industrial Case of Gamification in Software Quality Improvement(Serious Games Soc, 2023) Say, Bilge; Altunel, Haluk; Kosa, Mehmet; Koca-Atabey, MuejdeThe value of industrial-scale gamification interventions for improving software quality is a topic of interest for software engineering research; but it has not frequently been analysed from the perspective of the developer's experiences. The objective of this study is to qualitatively evaluate developers' experiences in a team-based, leaderboard-style gamification intervention in a large software house. To understand the dynamics of positive outcomes in improving code security and quality, semi structured interviews were conducted regarding both technical and psychosocial aspects. Eight members of three different leaderboard teams with different standings in the final leaderboard were interviewed, and the transcripts were examined using Interpretive Phenomenological Analysis. The results showed that the gamification intervention did result in positive individual and team-based awareness and behaviour change in a range of technical practices such as unit testing, code reviewing, and design. Post intervention, the participants discussed how their motivation, sense of belonging, and communication improved, also expressing concerns over attainability and fairness of gamification goals and relevance to existing workload. The experiential perspective emerging from analysed themes gives broader insights in technical and socio-psychological dimensions than available in the current literature.Article Citation - WoS: 5Citation - Scopus: 9Modeling Cultures of the Embedded Software Industry: Feedback From the Field(Springer Heidelberg, 2021) Akdur, Deniz; Say, Bilge; Demirors, OnurEngineering of modern embedded systems requires complex technical, managerial and operational processes. To cope with the complexity, modeling is a commonly used approach in the embedded software industry. The modeling approaches in embedded software vary since the characteristics of modeling such as purpose, medium type and life cycle phase differ among systems and industrial sectors. The objective of this paper is to detail the use of a characterization model MAPforES ("Modeling Approach Patterns for Embedded Software"). This paper presents the results of applying MAPforES in multiple case studies. The applications are performed in three sectors of the embedded software industry: defense and aerospace, automotive and transportation, and consumer electronics. A series of both structured and semi-structured interviews with 35 embedded software professionals were conducted as part of the case studies. The characterization model was successfully applied to these cases. The results show that identifying individual patterns provides insight for improving both individual behavior and the behavior of projects and organizations.
