The impact of working memory and the "process of process modelling" on model quality: Investigating experienced versus inexperienced modellers

A process model (PM) represents the graphical depiction of a business process, for instance, the entire process from online ordering a book until the parcel is delivered to the customer. Knowledge about relevant factors for creating PMs of high quality is lacking. The present study investigated the role of cognitive processes as well as modelling processes in creating a PM in experienced and inexperienced modellers. Specifically, two working memory (WM) functions (holding and processing of information and relational integration) and three process of process modelling phases (comprehension, modelling, and reconciliation) were related to PM quality. Our results show that the WM function of relational integration was positively related to PM quality in both modelling groups. The ratio of comprehension phases was negatively related to PM quality in inexperienced modellers and the ratio of reconciliation phases was positively related to PM quality in experienced modellers. Our research reveals central cognitive mechanisms in process modelling and has potential practical implications for the development of modelling software and teaching the craft of process modelling

Transformationales (Self-)Leadership: Self-Leadership und Transformationale Führung

Nach dem Leitsatz “Effektive (transformationale) Führung beginnt bei effektiver Selbstführung“ stellt der vorliegende Beitrag eine konzeptionelle Verbindung zwischen Self-Leadership und der transformationalen Führung her. Neben der jeweils getrennten Darstellung der beiden Konzepte hinsichtlich des aktuellen Kenntnisstandes erfolgt in weiterer Folge eine Analyse der Gemeinsamkeiten zwischen Self-Leadership und der transformationalen Führung. Auf Basis der konzeptionellen Analysen, theoretischen Grundlagen und empirischen Erkenntnisse wird das Transformationale (Self-)Leadership-Modell vorgestellt. Dieses zeigt auf, dass transformationale Führungskräfte in einem ersten Schritt selbst über entsprechende Self-Leadership-Fähigkeiten verfügen müssen, um ihre Geführten/Mitarbeiter effektiv führen und entwickeln zu können. In einem zweiten Schritt können die Geführten/Mitarbeiter ihre eigenen Self-Leadership-Fähigkeiten entwickeln und verbessern. Transformationale Führung liefert hierbei die notwendigen situativen Bedingungen

Working memory and its relation to deterministic sequence learning.

Is there a relation between working memory (WM) and incidental sequence learning? Nearly all of the earlier investigations in the role of WM capacity (WMC) in sequence learning suggest no correlations in incidental learning conditions. However, the theoretical view of WM and operationalization of WMC made strong progress in recent years. The current study related performance in a coordination and transformation task to sequence knowledge in a four-choice incidental deterministic serial reaction time (SRT) task and a subsequent free generation task. The response-to-stimulus interval (RSI) was varied between 0 ms and 300 ms. Our results show correlations between WMC and error rates in condition RSI 0 ms. For condition RSI 300 ms we found relations between WMC and sequence knowledge in the SRT task as well as between WMC and generation task performance. Theoretical implications of these findings for ongoing processes during sequence learning and retrieval of sequence knowledge are discussed

Information maintenance in working memory: An integrated presentation of cognitive and neural concepts

Working memory (WM) maintains information in a state that it is available for processing. A host of various concepts exist which define this core function at different levels of abstraction. The present article intended to bring together existing cognitive and neural explanatory approaches about the architecture and neural mechanisms of information maintenance in WM. For this, we highlight how existing WM concepts define information retention and present different methodological approaches which led to the assumption that information can exist in various components and states. This view is broadened by neural concepts focussing on various forms of phase synchronization and molecular biological mechanisms relevant for retaining information in an active state. An integrated presentation of different concepts and methodological approaches can deepen our understanding of this central WM function
