    A Neuroscientific View on the Role of Emotions in Behaving Cognitive Agents
    (KI - Künstliche Intelligenz: Vol. 25, No. 3, 2011) Vitay, Julien; Hamker, Fred H.
    While classical theories systematically opposed emotion and cognition, suggesting that emotions perturbed the normal functioning of the rational thought, recent progress in neuroscience highlights on the contrary that emotional processes are at the core of cognitive processes, directing attention to emotionally-relevant stimuli, favoring the memorization of external events, valuating the association between an action and its consequences, biasing decision making by allowing to compare the motivational value of different goals and, more generally, guiding behavior towards fulfilling the needs of the organism. This article first proposes an overview of the brain areas involved in the emotional modulation of behavior and suggests a functional architecture allowing to perform efficient decision making. It then reviews a series of biologically-inspired computational models of emotion dealing with behavioral tasks like classical conditioning and decision making, which highlight the computational mechanisms involved in emotional behavior. It underlines the importance of embodied cognition in artificial intelligence, as emotional processing is at the core of the cognitive computations deciding which behavior is more appropriate for the agent.

    Cognition and experience of employees in digital work environments
    (WM 2019 - Wissensmanagement in digitalen Arbeitswelten: Aktuelle Ansätze und Perspektiven - Knowledge Management in Digital Workplace Environments: State of the Art and Outlook, 2020) Leyer, Michael; Strohhecker, Jürgen
    Digital work environments are changing the learning experiences for employees. We provide an explanation on how the mechanisms of cognition and experience are connected and affected. First-order learning is reduced by machines which negative effects for second-order learning of employees. The analysis is a first step towards balancing digital support and experiences.

    Cognitive Endurance for Brain Health: Challenges of Creating an Intelligent Warning System
    (KI - Künstliche Intelligenz: Vol. 29, No. 2, 2015) Hedman, Anders; Hallberg, Josef
    During the past few years, the market for apps monitoring traditional health and wellbeing parameters such as heart rate, levels of physical activity and sleep patterns has rapidly expanded. In this paper, we articulate how we are currently engineering an early warning system designed to support long-term brain health, termed cognitive endurance, based on such monitoring. It can be thought of as a rudimentary expert system. It will monitor physical and social activity, stress and sleep patterns and signal when these parameters are such that a person’s cognitive endurance might be at risk. The aim of the system is to guide the user to adopt sustainable behavioral patterns from a cognitive endurance perspective. This paper articulates (1) what we mean by cognitive endurance, (2) how cognitive endurance may be enhanced, (3) our cognitive endurance monitoring platform, (4) our approach to calculating cognitive endurance risk, (5) specific challenges related to our approach and (6) what the long term benefits might be of successively monitoring cognitive endurance.

    Die Rolle von Affekt und Kognition bei der Gestaltung und Nutzung von Kollaborationswerkzeugen
    (HMD Praxis der Wirtschaftsinformatik: Vol. 56, No. 1, 2019) Benke, Ivo; Maedche, Alexander
    Digitale Zusammenarbeit ist in der heutigen Zeit allgegenwärtig und eröffnet große Chancen und Potentiale. Digitale Kollaborationswerkzeuge und soziale Medien, die diese Zusammenarbeit ermöglichen, sind somit zu ständigen Begleitern des Menschen geworden. Die Diversität von Aufgaben und Situationen, in denen sie verwendet werden, sowie die Heterogenität der Nutzer führt jedoch zu unterschiedlichen Herausforderungen im privaten und beruflichen Umfeld. Die Wissenschaft erforscht in den Bereichen physiologisches Computing und affektives Computing die Erfassung und Darstellung von affektiven und kognitiven Nutzerzuständen. Ein anschauliches Beispiel ist die Erfassung der mentalen Belastung von Autofahrern durch ein Elektro-Kardiogramm, um die Nutzer-Schnittstelle besser anzupassen. Die Anwendung der Erkenntnisse und Methoden dieser Forschungsfelder kann helfen, Probleme bei digitaler Kollaboration zu lösen. Dieser Artikel greift diese Entwicklung auf und gibt einen umfassenden, praxisnahen Überblick über die gegenwärtigen Arbeiten, die sich mit der Erfassung von affektiven und kognitiven Nutzerzuständen im Kontext von Kollaborationstechnologien und sozialen Medien beschäftigen. Basierend auf einer Auswahl von 111 Publikationen zeigen unsere Ergebnisse eine Zunahme von Untersuchungen über Kollaborationstechnologien (79 %), während soziale Medien (21 %) erst seit 2006 erwähnt werden. Gleichzeitig liegt ein starker Fokus auf der individuellen Ebene (66 %), wobei sich 54 % der Untersuchungen mit affektiven Nutzerzuständen beschäftigen. Abschließend gibt die Arbeit einen Ausblick über mögliche Anwendungsmethoden und -beispiele für die Praxis und beleuchtet potentielle Herausforderungen bei der praktischen Umsetzung. Nowadays, digital collaboration is omnipresent and opens up great opportunities and potentials. Digital technologies and social media tools realizing this collaboration have become constant companions of human beings. However, the diversity of tasks and situations in which they are used, as well as the heterogeneity of the users, leads to different challenges in the private as well as in the work context. In the fields of physiological and affective computing, science investigates the acquisition and representation of affective and cognitive user states. A demonstrative example is the recording of mental workload of car-drivers by an electro-cardiogram in order to better adapt the user interface to the user’s needs. The application of the findings and methods of these research fields may help to overcome problems in digital collaboration. This article picks up on this development and provides a comprehensive, practical overview of the current research work dealing with the acquisition of affective and cognitive user states in the context of collaboration technologies and social media. Based on a selection of 111 publications, our results show an increasing amount of research on collaboration technologies (79%), while social media (21%) have only been mentioned since 2006. At the same time, there is a strong focus on the individual level (66%), with 54% of the studies dealing with affective user states. Finally, this article gives an outlook on possible application methods and examples for practice and sheds light on potential practical obstacles.
