    Counteracting skill decay: four refresher
    (Taylor & Francis, 2014-02) ;
    Frank, Barbara
    In process automation, skill decay has not been investigated systematically. In two experimental studies, refresher interventions (RIs) were compared to support skill and knowledge retention of a start-up procedure on a simulated process control task. Based on theories of proceduralisation, the 'testing-effect' and mental practice, four different RIs were designed. In Study 1 (N = 68), two experimental groups (EGs) received either an RI called 'Practice' or an RI called 'Skill Demonstration'. Both RIs support skill retention, but the Skill Demonstration-RI performed with a higher mental workload. In Study 2 (N = 68), two EGs received an RI called 'Symbolic Rehearsal' or an RI called 'Procedural Knowledge Test', and aimed at supporting knowledge retention. Both EGs supported knowledge retention but showed moderate skill decay. Results imply that RIs affect skill and knowledge retention differently and should be applied in accordance with the task requirements and their dependence on accurate skill or knowledge maintenance.

    The Effects of a Scientifically Based Team Resource Management Intervention for Fire Service Teams
    (Inderscience Publishers, 2013)
    Hagemann, Vera
    ;
    Team resource management training for fire service teams has become increasingly popular. However, the effectiveness of this training, adapted from the well-established crew resource management training for flight crews, has not yet been evaluated for this audience. Ninety-one firefighters participated in a Team Resource Management seminar (experimental and control group) and in platoon leader training for conducting After Action Reviews (experimental group only). The intervention was evaluated, and its impact on knowledge acquisition, attitude, and behavioural changes at three different measurement times was assessed. The seminar was perceived as enjoyable and useful and participants stated an increase in knowledge, which was supported by an objective knowledge test assessment. Both the knowledge increase and three positively changed attitudes remained stable over the following seven months. Positive behavioural changes toward Team Resource Management were found in the experimental group only. Overall, the intervention proved to be effective according to several criteria.

    Enhancing Research on Training for Cognitive Readiness : Research Issues and Experimental Designs
    (Sage Journals, 2013-03) ;
    Burkolter, Dina
    In the present article, we aim to provide guidelines on how to conduct research for the enhancement of training for cognitive readiness (CR). After distinguishing between trainable CR skills and stable person-related variables, CR components that are trainable need to be defined in terms of knowledge, skills, and attitudes, and person-related variables need to be selected as prerequisites for training success, as they define the composite construct of CR. Training success in turn needs to include indicators of successful performance in unpredictable environments after training of CR that operationalizes temporal and adaptive transfer. We suggest a basic module for training-of-CR research, which includes a pretest measuring the baseline of the participants' knowledge, skills, and attitudes; person-related variables as control variables; predictors and moderators of CR training success; and two posttests for the assessment of training performance directly after training and following a retention interval for both temporal and adaptive transfer. For further research, we suggest extending the basic module with research on spacing of practice, performance under stress, and individual differences in cognition and personality. This research will enhance the understanding of the interplay between person- and training-related variables that best predicts the prerequisites for establishing and sustaining competent performance in complex and stressful environments.

    Process control and risky decision-making: moderation by general mental ability and need for cognition
    (Taylor Francis, 2012-08-17)
    Burkolter, Dina
    ;
    Human factors and ergonomics research could benefit from focusing more strongly on individual differences - especially trait variables. The present study suggests the analysis of moderator effects as a promising way to enhance understanding of trait variables and process control performance. Process control performance was studied by analysing moderator effects of general mental ability (GMA) and need for cognition (NC) on risky decision-making (RDM) and performance. Fifty engineering students were trained on a process control task using a computer-based simulation for three hours and tested twice thereafter. Risky decision-making was measured using a computerised gambling task while GMA and NC were assessed with questionnaires. Risky decision-making in interaction with each GMA and NC explained variance in performance over and above variance explained by the single effects. In conclusion, the analysis of moderator effects between individual difference variables and process control performance seems promising.

    Flexibility under complexity: Work contexts, task profiles and team processes of high responsibility teams
    (Emerald, 2012-03)
    Hagemann, Vera
    ;
    ;
    Ritzmann, Sandrina
    Purpose - The purpose of the present study is to introduce the elements characterising the work context of high responsibility teams (HRTs) operating in high reliability contexts such as medicine or aviation. Based on these elements, the authors reflected on the function of teamwork in these contexts, which is strongly dominated by a notion of flexibility under complexity, based on the technical, normative, and governance dimensions of teamwork. Design/methodology/approach - Problem-centred interviews (n=11) based on semi-structured guidelines were conducted. Subsequently, a survey was conducted using a questionnaire inventory in six different HRT work contexts (n=551). Findings - The interviews and survey results show significant differences regarding, for example, hierarchy or stress posed on the HRTs. However, they also demonstrate relevant similarities regarding, for instance, dimensions of complexity occurring in the teamwork contexts. Both differences and similarities influence how the support systems of the teamwork dimensions should be set up. Research limitations/implications - The study provided an excellent overview of similar and differing characteristics of the work context of different HRTs. However, it represents six specific HRTs and might not be generalisable to teams in other high reliability organisations, such as in the energy sector. Practical implications - It is recommended that the characteristics of work contexts in HRTs should be taken into account in order to set up support systems of teamwork dimensions that enable teams to transfer the prevalent safety discourse into safety practice. Originality/value - The innovative approach, which combines qualitative and quantitative data, provided insights that can be used to support team functioning in the team's specific work context.

    Online consumer behavior and its relationship with socio-demographics, shopping orientations, need for emotion, and fashion leadership
    (Hochschule Fresenius, 2011-04)
    Burkolter, Dina
    ;
    With online shopping entering a consolidation phase, there is a need for research differentiating online consumer behavior for a range of prod-uct categories. Also, individual differences in online shopping need to be considered. Therefore, a survey (N = 405) assessing online infor-mation search and online shopping for nine different product categories as well as socio-demographic and individual variables (shopping orien-tation, need for emotion, and fashion leadership) was conducted in Germany. Results showed significant differences in online information search as well as shopping regarding gender, status of employment, and education. Moreover, individual variables were differently related to online shopping behavior. Findings are discussed with respect to the future development of the internet as well as scientific and practical in-sights.

    Recurrent training of cabin crew should include theoretical and practical instruction on safety as well as crew resource management (CRM) issues. The endeavors of Swiss International Air Lines Ltd. and Swiss Aviation Training Ltd. to integrate CRM and safety aspects into a single training module were evaluated. The objective of the integration was to make CRM more tangible and ease acquisition of competencies and transfer of CRM training content to practice by showing its relevance in relation to safety taskes. It was of interest whether the integrated design would be mirrored in a more favorable perception by the trainees as measured with a questionnaire. Participants reacted more positively to the integrated training than to stand-alone CRM training, although the integrated training was judged as being slightly more difficult and less oriented toward instructional design principles. In a range of forced-choice questions, the majority of participants opted for an integrated training format because it was seen as livelier and more interesting and also more practically relevant. For the forthcoming training cycle, a better alignment of training with instructional principles and an even higher degree of training integration by using simulator scenarios are striven for.
