Dallas and Merikle (1976a, 1976b) demonstrated that when participants were presented with a pair of words for over 1 s and subsequently cued to pronounce one of the words aloud (postcue task) semantic priming effects occurred. Humphreys, Lloyd-Jones, and Fias (1995) failed to replicate this postcue semantic priming effect using word pairs that were semantic category co-ordinates. The aim of Exp...

Focusing attention on a limited space within the environment allows us to concentrate our resources selectively on that location while ignoring the rest of the space. In this study we investigated how the deployment of the focal attention in foveal vision can be affected by task and stimuli specificity. In particular, we measured the cue-size effect in four experiments: shape detection (Experim...

In this study, we examined the nature of the spatial-numerical associations underlying the SNARC-effect by imposing a verbal or spatial working memory load during a parity judgment and a magnitude comparison task. The results showed a double dissociation between the type of working memory load and type of task. The SNARC-effect disappeared under verbal load in parity judgment and under spatial ...

Augmentative and Alternative Communication (AAC) devices include special purpose electronic devices that generate speech output and are used by individuals to augment or replace vocal communication. Word prediction, including context specific prediction, has been proposed to help overcome barriers to the use of these devices (e.g., slow communication rates and limited access to situation-relate...

This article examines the influence of task type on the users’ preferred level of document elements (full articles, sections or subsections) during interaction with an XML-version of Wikipedia. We found that in general articles and subsections seemed to be the most valuable elements for our test subjects. For information gathering tasks this tendency was stronger whereas for factfinding tasks t...

In this paper, we review the literature on efficient task scheduling on multi-core system. The number of cores on one chip are increasing very rapidly. For achieving high performance without more power consumption and without heating up the system, multi-core processing technology is used. In addition for fully utilization of system resources in more efficient way task scheduler are developed, ...

objectives: the present study aimsed to examine the reliability of forceplate parameters under both single and dual task conditions and in different levels of postural difficulty. methods & materials: the healthy elderly+65, were assessed with aone-week interval, with a random combination of three levels of postural difficulty (i.e., standing on a rigid surface with eyes open, standing on a rig...

Success in finding information in a website depends not only on the complexity of the information retrieval task per se but also on the way information is made accessible. We explored the role of navigation menus when performing information retrieval tasks. We compared expandable menus with sequential menus. Expandable menus preserve the full context of choice while the user is browsing. Sequen...

We investigated task switching among four tasks by means of a modified cuing procedure with two types of cues. One type of cue consisted of a standard task cue indicating the next task. In half of the trials, this task cue was preceded by another type of cue that reduced the set of candidate tasks from four to two tasks. In addition, we measured participants' spontaneous eye blink rates (EBRs) ...

We compare four subjective awareness measures in the context of a visual identification task and investigate quantitative differences in terms of scale use and correlation with task performance. We also analyse the effect of identification task decisions on subsequent subjective reports. Results show that awareness ratings strongly predict accuracy for all scale types, although the type of awar...
