The use of eye movements to study cognitive effort is becoming increasingly important in HCI research. Eye movements are natural and frequently occurring human behavior. In particular fixations represent attention; people look at something when they want to acquire information from it. Users also tend to cluster their attention on informative regions of a visual stimulus. Thus, fixation duratio...

Choice conflicts between one's important values may cause negative emotion. This article extends the standard effort-accuracy approach to explaining task influences on decision processing by arguing that coping goals will interact with effort minimization and accuracy maximization goals for negatively emotion-laden decision tasks. These coping goals may involve both a desire to process in a tho...

We consider a setting in which a worker and a manager may each have information about the likely completion time of a task, and the worker also affects the completion time by choosing a level of effort. The task itself may further be composed of a set of subtasks, and the worker can also decide how many of these subtasks to split out into an explicit prediction task. In addition, the worker can...

This study examines the acceptance and use of ICT by Nigerian university academicians. The model validated is the Unified Theory of Acceptance and Use of Technology (UTAUT). Using a pilot study, one hundred questionnaires were administered and collected at the University of Jos Plateau State, Nigeria. The construct was significantly correlated with behavioral intention (BI). This implies that t...

Because impulsive decision-making is correlated with many maladaptive tendencies, researchers have increasingly studied methods for reducing choice. These efforts primarily focused on increasing choices of larger, more-delayed rewards. A second type choice selecting a smaller, less-effortful reward over more-effortful one. Little nonhuman research has examined experimental effort-based Within t...

Background: Multiple Sclerosis (MS) syndrome is a type of Immune-Mediated disorder in the central nervous system (CNS) which destroys myelin sheaths, and results in plaque (lesion) formation in the brain. From the clinical point of view, investigating and monitoring information such as position, volume, number, and changes of these plaques are integral parts of the controlling process this dise...

On what basis are the input processing capabilities of Natural Language software judged? That is, what are the capabilities to be described and measured, and what are the standards against which we measure them? Rome Laboratory is currently supporting an effort to develop a concise terminology for describing the linguistic processing capabilities of Natural Language Systems, and a uniform metho...
