An Evolutionary Upgrade of Cognitive Load Theory: Using the Human Motor System and Collaboration to Support the Learning of Complex Cognitive Tasks

Cognitive load theory is intended to provide instructional strategies derived from experimental, cognitive load effects. Each effect is based on our knowledge of human cognitive architecture, primarily the limited capacity and duration of a human working memory. These limitations are ameliorated by changes in long-term memory associated with learning. Initially, cognitive load theory's view of human cognitive architecture was assumed to apply to all categories of information. Based on Geary's (Educational Psychologist 43, 179-195 2008; 2011) evolutionary account of educational psychology, this interpretation of human cognitive architecture requires amendment. Working memory limitations may be critical only when acquiring novel information based on culturally important knowledge that we have not specifically evolved to acquire. Cultural knowledge is known as biologically secondary information. Working memory limitations may have reduced significance when acquiring novel

Creative Thinking and Modelling for the Decision Support in Water Management

This paper reviews the state of art in knowledge and preferences elicitation techniques. The purpose of the study was to evaluate various cognitive mapping techniques in order to conclude with the identification of the optimal technique for the NetSyMod methodology. Network Analysis Creative System Modelling (NetSyMod) methodology has been designed for the improvement of decision support systems (DSS) with respect to the environmental problems. In the paper the difference is made between experts and stakeholders knowledge and preference elicitation methods. The suggested technique is very similar to the Nominal Group Techniques (NGT) with the external representation of the analysed problem by means of the Hodgson Hexagons. The evolving methodology is undergoing tests within several EU-funded projects such as: ITAES, IISIM, NostrumDSS

Effects of the information environment on group discussions and decisions in the hidden-profile paradigm

Research on the Information Sampling Model (ISM) revealed that information items that are known to all group members at the outset (shared information) are more likely to be mentioned during discussion than information items that are only known to individual members (unshared information) (Stasser & Titus, 1985; Wittenbaum, Hollingshead, & Botero, 2004). In prior studies involving the ISM, groups typically functioned in a very specific information environment: All information items were provided in form of unique cues, which described only one of the choice alternatives among which the groups had to choose. Because this specific information environment may impact group discussions and decisions, we included an experimental condition incorporating common cues. In contrast to unique cues, common cues provide information on each and every choice option. As expected, groups in the common-cue condition showed a weaker sampling advantage for shared information, and chose the hidden-profile alternative more often than groups in the classic unique-cue condition
