Mental rotation with and without a concurrent task: moderating effects of visuospatial ability
… Form Board), performed a computer-administered task requiring the mental rotation of abstract geometric shapes presented sequentially, either alone or with a concurrent task of repeating sets of six random digits. Gender and skill-level effects were found. Men were faster than women, and high …

Effects of Encoding Variety and Concurrent-Task Practice on the Transfer and Retention of Complex Skill
… present study investigated the effects of dual-task practice and the variety of problems solved during practice on (a) the acquisition of procedural and declarative skills and the development of concurrent-task skills, and (b) the utilization and maintenance of two types of strategies. …

Integrating Imperfect Automated Aids Into a Multi -Task Situations
… particular events or situations during complex tasks. Automated aids can be useful by taking over a function once performed by the human thereby freeing up the person to do other tasks. However, automated aids may also introduce costs to task performance that are not readily apparent. In four …

The Effects On Operator Performance And Workload When Gunnery And Robotic Control Tasks Are Performed Concurrently
… workload and performance in a high risk, multi-task environment. Specifically, the research examined if a gunner of a Future Combat System, such as a Mounted Combat System, could effectively detect targets in the immediate environment while concurrently operating robotic assets in a remote …

Let's get physical: the dual-task costs of multiple motor responses
Dual-task costs occur when attention is divided among two or more concurrent tasks. Most dual-task studies involve paradigms where participants complete two, concurrent cognitive tasks; in these studies, performance on one or both tasks are slower and/or less accurate. The goal of this study was to …

Explorations of Perceived Product Efficacy
… longer) duration judgments when they perceive a concurrent task to be relatively difficult (vs. easy). The effect of perceived task difficulty on duration judgments of product efficacy is (1) established with energy-enhancing products and medication, (2) shown to be driven by an intuitive belief …

Design of an Automation Framework for a Novel Data-Flow Processor Architecture
… which are identified as event-driven nature with concurrent task execution and deterministic timing behavior. Additionally, to reduce the design complexity of applications on this novel architecture, an automation framework has been implemented. This thesis presents the design of the processor …

A Transformation-based Approach to Building Multi-Platform User Interfaces Using a Task Model and the User Interface Markup Language
… UIs (MPUIs) are identified and specified. A task model, which is an abstract representation of the tasks that users perform with a system, is used as a high-level platform-independent specification for representing UIs for multiple platforms. The task model is supplemented with additional …

Dual Process Models of Decision Making: An fMRI Investigation of Framing Effects and Individual Differences
… accounts of decision making, the examination of concurrent task demands and individual differences in the manifestation of framing effects could serve to inform dual-process models. The current studies examined two different framing paradigms in the context of experimental manipulations, …

Efficient architectures of heterogeneous fpga-gpu for 3-d medical image compression
… and throughput. Next, OpenCL implementation for concurrent task via dedicated FPGA. Finding from implementation reveals, OpenCL on batch procession mode with AOC techniques offers substantial results where the amount of logic, area, register and memory increased proportionally to the number of …

The Effects of Task Preference on Speech and Motor Performance Under Divided Attention Conditions
<p>Dual task performance and the interaction of tasks has been the subject of much research. When tasks are performed together they affect each other to varying degrees depending upon such factors as the similarity of the tasks, their difficulty, and whether one task is given preference over …

Essays on attention and creative thought
… prioritize the information relevant to the concurrent tasks less, why does mind wandering sometimes improve rather than impair concurrent task performance? I resolve the puzzle by rejecting the standard conception of attention, according to which the more focused one’s attention is, the …

Model based approach for context aware and adaptive user interface generation
… studied and we define a context model on top of task model to introduce the contextual conditions into user interface generation process. Using the context model, user interface designer can specify contextual requirements and its effect on the user interface. Third, context aware adaptation of …

The Effects of Divided Attention on Speech Motor, Verbal Fluency and Manual Motor Task Performance
Research in dual task performance varies widely in its methodology and results. The present study employed three different types of activity to provide insights into the interference that occurs in dual task performance. Twenty young adults completed a speech task (repeating a sentence), a verbal …

Adaptive modality selection for navigation systems
… in order to safely and effectively perform their tasks. When these people -- such as soldiers in combat or first responders in disaster areas -- need to navigate through various areas in addition to performing other concurrent tasks, the combination can easily result in sensory or attentional …
