Abstract Multitasking research in the laboratory is dominated by extremely simplistic dual-task paradigms. Although dual-tasks allow for some variations, they do not compare well to more complex everyday task settings. This study expands a classical paradigm adding third task. The and triple-task always consisted of same three single tasks. aim was investigate effects combinations single-tasks ...

Consider a scheduling problem of parallel computations in multiprocessor systems. Let a parallel program be modeled by a task graph, where vertices represent tasks and arcs the communications between tasks. An interprocessor communication time incurs when two tasks assigned to two diierent processors have to communicate. Such a scheduling problem has recently been studied in the literature, mos...

We present a comparison between two systems for establishing syntactic and semantic dependencies: one that performs dependency parsing and semantic role labeling as a single task, and another that performs the two tasks in isolation. The systems are based on local memorybased classifiers predicting syntactic and semantic dependency relations between pairs of words. In a second global phase, the...

We combine the Dimension-Action (DA) model with translational models to account for both the Stroop and the flanker effects. The basic assumption of the model is that there are distinct visual modules, each of which is endowed with both perception and response selection processes. We contrast this model with an alternative widespread view, the standard view, according to which the same response...

Two experiments used the locus-of-cognitive-slack method to determine whether dual-task interference occurs before or after the response selection stage. The experiments used the overlapping tasks paradigm, in which two signals, each requiring a different speeded choice response, are presented in rapid succession. In Experiment 1, stimulus-response (S-R) compatibility was manipulated by varying...

Vernier acuity is a measure of the smallest horizontal offset between two vertical lines that can be behaviorally discriminated. To examine the link between the neuronal responses in a retinotopic mosaic and vernier acuity, we recorded the responses of single cells in cat lateral geniculate nucleus to a vertical bar stimulus that was stepped in small increments through the receptive fields of c...

Multi-robot task allocation research has focused on sequential single-item auctions and various extensions as quick methods for allocating tasks to robots with small overall team costs. In this paper we outline the benefits of grouping tasks with positive synergies together and auctioning clusters of tasks rather than individual tasks. We show that with task-clustering the winner determination ...

This paper presents our experience implementing three approaches for the ‘PAN 2014 Author Identification’ [3,1] task using the same representation for the author’s style. Two of our approaches extend previous successful approaches: naive Bayes [4] and impostor [8] methods. The third approach is based on original research on sparse representation for text documents. We present results with the o...

There is no consensus regarding the origin of behavioral interference that occurs during concurrent multitasking. Some evidence points toward a multitasking locus in the brain, while other results imply that interference is the consequence of task interactions in several brain regions. To investigate this issue, we conducted a functional MRI (fMRI) study consisting of three component tasks, whi...
