We live in the age of complexity. Yet, complexity is rarely studied in MIS. The paper studies cognitive complexity in an important IS domain – data modeling. The focus is on novice data modelers. Four major sources of complexity principles are identified: problem solving principles, design principles, information overload, and systems theory. Based on prior literature, the factors that lead to ...

Adoption and maintenance of health behaviors require two separate processes that take place in a motivation phase and in a volition phase. First, an intention to change is developed, among others, on the basis of self-beliefs. Second, self-regulation is at stake when it comes to planning, initiating, maintaining, and relapse management. Social cognition models of health behavior change address ...

Nutritional factors and nutritional deficiencies have been repeatedly associated with cognitive impairment. Most of the evidence is based on cross-sectional studies, which cannot prove whether a nutritional deficit is the cause or the consequence of an impaired cognitive status. In fact, cognitive impairment, in turn, can determine changes in dietary habits and consequent nutritional deficienci...

Prior probabilities are central to Bayesian statistics. The Bayesian paradigm assumes that people can express uncertainty in terms of subjective probability distributions. This article will consider Hogarth's 1975 assessment that \man is a selective, sequential information processing system with limited capacity,. .. ill-suited for assessing probability distributions." Particular attention will...

Alzheimer disease and vascular cognitive impairment are important causes of cognitive decline in the elderly. It has now been shown that vascular risk factors have measurable negative effects on the brain and are associated with cognitive impairment. We review vascular factors that might be responsible to cognitive decline in Alzheimer disease and vascular cognitive impairment and the correspon...

The recent integration of telephony systems with information and communication technology (ICT) enables the development of innovative tools for telemedicine. The dissemination and widespread acceptance of telephone-based care monitoring systems challenge the researcher to deal with the cognitive factors involved in the patient-physician interaction, and the way they should be to shape up the te...

BACKGROUND Potentially modifiable lifestyle factors may influence cognitive health in later life and offer potential to reduce the risk of cognitive decline and dementia. The concept of cognitive reserve has been proposed as a mechanism to explain individual differences in rates of cognitive decline, but its potential role as a mediating pathway has seldom been explored using data from large ep...
