Individual differences and the user interface

Individual differences in cognitive functions are relevant in introducing novioes to computing. The interaction between the user and the computer may be improved if these psychological characteristics are taken into account in the design of the user interface and in the design of introductory courses. In.section 1 of this paper an analysis is made of individual differences and of the possibilities of adaptation. The user interface is described as an opportunity for adaptation. Methods of adaptation are systematically related to the changeability of individual differences. Illustrated by an overview of previous experimental work, some principles of adaptation are demonstrated in relation to individual differences on variables that are relevant in human-computer interaction. Prior knowledge of mathematics has been shown to be related to success and failure in learning a programming language, and to motivation for using computers. In section 2 ways to prevent the course drop-out rate by structuring the teaching method are illustrated. Strategies of information processing in the user interface, in relation to metacommunication and teaching, are described in section 3 as another example of an individual difference variable that may be attended to in teaching, resulting in reduction of problem solving time. Some cognitive styles are related to success in programming. The choice of adequate educational examples may improve programming habits, as illustrated in section 4. Style of representation and spatial ability are relevant for the development of mental models of computer system. In section 5 some field studies on teaching novices to work with office systems illustrate these relations. Teaching strategies, educational examples, and metaphors, may neutralize the handicap some novices have because of these variables.     

Contributions of Dichotomic View of plasticity to seamlessly embed accessibility and adaptivity support in user interfaces

Recent legal changes have increased the need for developing accessible user interfaces in computer-based systems. In this sense, previously existing user interfaces are intended to be modified and new user interfaces are intended to be designed taking accessibility guidelines into account. Typically, model-based approaches have been used when developing accessible user interfaces or redefining existing ones. But the use of static models leads to the development of not dynamically adaptable user interfaces. Dynamic adaptation in accessible user interfaces is important due to the fact that interaction difficulties on people with disabilities may change through use. In this paper, we present some contributions that can be obtained from the application of the Dichotomic View of plasticity in the personalization of user interfaces. With the double perspective defined in this approach, it is intended to go further from a mere adaptation to certain user stereotypes, offering also a dynamic support to real limitations or difficulties users can encounter during the use of the UI. This goal is achieved analyzing user logs by an inference engine that dynamically infers modifications in the user interface to adjust it to varying user needs. A case study is presented in order to show how the guidelines and software support defined in the Dichotomic View of plasticity can be applied to develop a component for a particular system aimed at performing dynamic user interface adaptations with accessibility purposes. This approach includes some innovations that make it different from conventional adaptable mechanisms applied to accessibility in some important aspects.     

Taking fun seriously: Using cognitive models to reason about interaction with computer games

This paper seeks to extend the application of techniques from affective psychology to show how cognitive models can be used to represent and reason about interaction with computer games. It is argued that this modelling activity provides insights into the motivational appeal that often distinguishes computer games from other forms of human computer interaction. The long-term aim behind this research is to use our improved understanding of interaction with computer games to inform the subsequent development of more general classes of interactive systems. Barnard's Interacting Cognitive Subsystems (ICS) is used throughout this paper. This decision is justified by the fact that ICS has already been applied to analyse the negative emotions surrounding clinical depression. This previous work provides a useful starting point for our investigation of the more positive emotions evoked during interaction with computer games. A further justification is that ICS has also been successfully used to represent and reason about the design of human computer interfaces.     

Effects of Collaborative Web Based Vocational Education and Training (VET) on Learning Outcomes

Considering the increase in need of skilled human capital, the vocational training and education through e-learning has widely been adopted all over the world. It serves as a major alternative for training and teaching professionals, technicians, skilled workers, amateurs and students who cannot manage regular college education due to time, cost and distance factors. Prior research focuses on learning enhancement from several perspectives like computer mediated methods, learning games, personalized learning environments and web based instructional design. The proposed work contributes to this debate by investigating the role of collaboration i.e. student–student and student–instructor interaction, support material, instructor's feedback and evaluating their effects on learning outcome and students' learning experience. The investigation is performed through a case study presenting four vocational courses offered in three consecutive sessions. The findings revealed that collaborative practices i.e. group work, team effort, in time instructor's feedback and consolidated support material enhances learning experience of student and contributes positively to the learning outcome.     

Preference-inconsistent recommendations: An effective approach for reducing confirmation bias and stimulating divergent thinking?

The Web is a perfect backdrop for opinion formation as a multitude of different opinions is publicly available. However, the different opinions often remain unexploited: Learners prefer preference-consistent over preference-inconsistent information, a phenomenon called confirmation bias. Two experiments were designed to test whether technologies such as recommender systems can be used to overcome this bias. The role of preference-inconsistent recommendations was explored by comparing their influence to a condition with preference-consistent recommendations and to a control condition without recommendations. In Study 1, preference-inconsistent recommendations led to a reduction of confirmation bias and to a more moderate view of the controversial topic of neuro-enhancement. In Study 2, we found that preference-inconsistent recommendations stimulated balanced recall and divergent thinking. Together these studies showed that preference-inconsistent recommendations are an effective approach for reducing confirmation bias and stimulating divergent thinking. In conclusion, future research and practical implications are discussed.
