The Driving to Learn project explored ways to help people with profound cognitive disabilities practice operating a joystick-operated powered wheelchair. The project used a grounded theory approach with constant comparative analysis and was carried out over 12 yr. The participants were 45 children and adults with profound cognitive disabilities. Reference groups included 17 typically developing...

Goal-oriented human-machine situation-awareness systems focus on the challenges related to perception of the elements of an environment and their state, within a time-space window, the comprehension of their meaning and the estimation of their state in the future. Present computer-supported situation awareness systems provide realtime information fusion from different sources, basic data analys...

I review a variety of behavioral studies directed at understanding how probability and value information is represented in motor and cognitive tasks. Subjects in (cognitive) decision-making tasks often misrepresent the frequency of rare events and typically fail to maximize expected gain. In contrast, subjects in mathematically equivalent movement tasks are generally found to be very good at ch...

Children as young as age 3 understand that different people have different areas of expertise (i.e., the division of cognitive labor) and they choose information sources accordingly (e.g., Lutz & Keil, 2002). However, it is unclear whether this understanding depends primarily on social cognitive skills, such as an appreciation of others’ mental states, or non-social cognitive skills, such as th...

Since electronic and open environments became a reality, computational trust and reputation models have attracted increasing interest in the field of multiagent systems (MAS). Some of them are based on cognitive theories of reputation that require cognitive agents to display all their potential. One of them is Repage, a computational system based on a cognitive theory of reputation that focuses...

There is considerable controversy about the necessity of cognitive assessment as part of an evaluation for learning and attention problems. The controversy should be adjudicated through an evaluation of empirical research. We review five sources of evidence commonly provided as support for cognitive assessment as part of the learning disability (LD) identification process, highlighting signific...

Cognitive rehabilitation is an empirically based field driven y multiple sources of activities and knowledge bases. Drawng on frames of reference provided by rehabilitation, neurosychology, and rehabilitation psychology, cognitive rehabiliation has evolved to a point where studies have been generated o qualify for consideration in tables of evidence. At the center f cognitive rehabilitation is ...

The nature of fluid intelligence was investigated by identifying variables that were, and were not, significantly related to this construct. Relevant information was obtained from three sources: re-analyses of data from previous studies, a study in which 791 adults performed storage-plus-processing working memory tasks, and a study in which 236 adults performed a variety of working memory, upda...
