The influence of perceived task difficulty on task performance
… the influence that the perceived difficulty of a task has on task performance. Twenty-one undergraduate college students were asked to complete three anagram worksheets. Each worksheet had a different description of difficulty (easy, medium, hard), although all worksheets were of the same …

Effects of Control Device and Task Complexity on Performance and Task Shedding During a Robotic Arm Task
… research was to investigate the difference in task performance when using two different control devices at high and low task complexities when participants can shed tasks to automation. In this experiment, 40 undergraduates (24 females) used two control devices, a Leap Motion controller and an …

Task-Dependent Oscillatory Brain Activity During Oculomotor Delayed Response Task
… used three Oculomotor Delayed Response (ODR) tasks to investigate the unique cognitive demands during the delay period. Changes in alpha power were used to index cognitive efforts during the delay period. Continuous EEGs from 25 healthy young adults (18-34 years) were recorded using dense …

Task Components and Demands as Factors in Dual-Task Performance
Made available in DSpace on 2014-12-13T18:21:49Z (GMT). No. of bitstreams: 1 7714997.pdf: 4238171 bytes, checksum: f02d64cb9a57c799d3091c865d2cb044 (MD5) Previous issue date: 1977

Learning Heterogeneous Resource-Constrained Task Allocation Using Concurrent Multi-Task Bandits
Task allocation is a critical aspect of multi-robot coordination, enabling the completion of complex tasks that would be intractable for individual robots. However, existing approaches to task allocation often assume that task requirements or reward functions are known and explicitly specified by …

Generalized Task Structure Learning for Collaborative Multi-Robot/Human-Robot Task Allocation
… multi-robot systems focusing on the problem of task allocation under hierarchical constraints imposed upon a joint task. For these types of tasks, multiple robots need to dynamically coordinate their execution during the task execution. However, due to the different abilities between different …

Optimal Task Scheduling and Flight Planning for Multi-Task Unmanned Aerial Vehicles
… the UAV is capable of conducting multiple tasks simultaneously. Coordinating different tasks to a multi-task UAV can be challenging. The reason is that tasks may require different levels of commitment and tolerate different latencies. Another reason is that multi-tasking can give rise to …

Task Localization, Similarity, and Transfer; Towards a Reinforcement Learning Task Library System
<p>This thesis develops methods of task localization, task similarity discovery, and task transfer for eventual use in a reinforcement learning task library system, which can effectively “learn to learn,” improving its performance as it encounters various tasks over the lifetime of the learning …

Asynchronous neighborhood task synchronization
… a new problem, called asynchronous neighborhood task synchronization ( NTS ). In this problem, processes execute infinite instances of tasks, where a task consists of a set of steps. There are several requirements for this problem. Simultaneous execution of steps by the neighbors is allowed only …

Task Switching and Distractibility
In this thesis I examined the effects of task switching on people’s ability to ignore irrelevant distractors. Load theory proposes that distractor interference critically depends on the availability of executive control to minimise the effects of irrelevant stimuli (e.g. Lavie, 2000). Much work on …

Task Scheduling and Productivity
… tendencies, evaluate the impact considering task end-times have on scheduling tendencies, and to assess links between scheduling tendencies and productivity. Throughout four studies, findings indicated that participants consistently preferred to schedule tasks on-the-hour (e.g., 9:00 or 10:00 …

Formalizing operator task analysis
… can cause them to erroneously execute a given task description to operate a computer system. Usually, a computer system is protected against some erroneous human behaviors by having necessary safeguard mechanisms in place. But some erroneous human operator behaviors can lead to severe or even …

Learning task-specific similarity
… which tends to depend on the underlying task. We develop an algorithmic approach to learning similarity from examples of what objects are deemed similar according to the task-specific notion of similarity at hand, as well as optional negative examples. Our learning algorithm constructs, …

The relationship between working memory and cognitive control : the role of task complexity, organisational strategies and task-switching on the task-span procedure
… long-term memory, and action. Using the task-span procedure developed by Logan (2004), the current thesis aimed to examine some of the most salient features of working memory. Specifically how processing and storage interact with working memory, the influence of organisational factors on …

The Effects of Task Criticality and Target Modality on a Simulated Battlefield Search Task
… instruction manuals when asked to perform tasks in critical environments. These instruction manuals are predominantly written in text and rarely include images. Several theoretical frameworks, including the Pictorial Superiority Effect, posit images to be more effective forms of instruction …
