Cognitive Informatics (CI) is a contemporary multidisciplinary field spanning across computer science, information science, cognitive science, brain science, intelligence science, knowledge science, cognitive linguistics, and cognitive philosophy. CI aims to investigate the internal information processing mechanisms and processes of the brain, the underlying abstract intelligence theories and d...

Introduction: The current study aimed to elucidate the role of preparatory cognitive control in decision making and its neural correlates using functional Magnetic Resonance Imaging (fMRI). To this effect, by employing a series of new cognitive tasks, we assessed the role of preparatory cognitive control in monetary (risky) decision making. Methods: The participants had to decide between a...

Background: Cognitive failure is mental lapses in perception, attention, memory, and action. It occurs during routine tasks that one would usually have no difficulty in successfully completing. Cognitive performance is influenced by conditions and some individual and job characteristics and the identification of factors that affect human performance is essential to prevent human error. The purp...

Recent work demonstrates that process data from intelligent tutoring systems (ITSs) can be used to predict student outcomes on high-stakes, standardized tests. Such models are important if ITSs are to be used for formative assessment and as replacements for external assessments. Recent work used various measures of learning efficiency and performance from problem-level, aggregate data from Carn...

In a premier paper on the information-theoretic analysis of a two-user cognitive interference channel (CIC) [1], Devroye et al. presented an achievable rate region for the two-user discrete memoryless CIC. The coding scheme proposed by Devroye et al. is correct but unfortunately some rate-terms in the derived achievable rate region are incorrect (in fact incomplete) because of occurring some mi...

A key role for the knowledge sharing on the Web is the constructive interaction between system and user. It is presented an application implemented on Cicerobot, a RWI B21 autonomous robot. It is based on a cognitive architecture and works on tasks related with guided tours in the Archaeological Museum of Agrigento. Interaction between Cicerobot and the user is based on a first step towards sem...

We consider the problem of efficient opportunistic spectrum access in cognitive radio networks where there are multiple secondary users trying to share access to multiple channels. In our formulation, each user has a potentially different valuation of each channel and wishes to pick a channel in such a way as to maximize its benefit without interfering with other users. There is a fundamental t...
