Brain Dynamics When Alertness Fluctuates but Attentional Demands Persist
… reorganises when alertness levels decline but attentional demands persist. We focused on sustained auditory and visual attention using functional magnetic resonance imaging (fMRI). First, we examined how sustained auditory attention impacts brain functional reorganisation during sleep onset. We …

The Attentional Demands of Positive Reappraisal in a Dual Task Paradigm
… reappraisal requires attention, and that the attentional demands required to use this strategy can impact performance in other areas. The present study sought to expand on these findings by examining an understudied type of cognitive reappraisal: positive cognitive reappraisal. Furthermore, …

Visual Enumeration and Estimation: Brain mechanisms, Attentional demands and Number representations.
… First, a distinction was made between different attentional modes underlying estimation and enumeration in an in-depth single case study of a patient with simultagnosia. Subsequently I demonstrated that, in visual enumeration, subitizing and counting are dissociable processes and they rely on …

Attentional demands do affect amplitudes of N1 and N2 in the sensory gating paradigm in neurotypical adults and children
Past research has shown that N1 and N2 ERP components may be related to attention; however, few studies have measured N1 and N2 amplitudes when attention was manipulated. In this study, two ERP sensory gating paradigms were used in which attention was manipulated by requiring participants either to …

Neurology of Attention: Interhemispheric Processing Modulates Attention in the Stroop Task
… helps modulate processing during increased attentional demand. The data suggest that interhemispheric processing (1) is not a static, but instead varies with task demands, (2) produces non-random responses to attentional demands, and (3) is a unique form of neural processing not necessarily …

L2 Phonetic Detail in L1 Lexical Processing
… in each task. In auditory lexical decision, when attentional demands were low, these listeners were very intolerant of L2 English phonetic detail in L1 Spanish words, as seen in delayed responses and low acceptance rates. In contrast, when attentional demands were elevated in the cross-modal …

The Use of Speech Recognition Technology in Automotive Applications
… on speech recognition technology and the attentional demands of driving; (2) to develop decision tools that assist designers of in-vehicle systems; (3) to experimentally examine automatic speech recognition (ASR) design parameters, input modalities, and driver ages; and (4) to provide …

Development of an evaluation program for automotive instrument panel design
… objectives of which were (I) to characterize attentional demands of drivers performing automoltive instrument panel (IP) tasks, (2) to develop a methodology to quantify the driver attentional demands, (3) to examine a variety of factors which influence the visual attentional demand (VAD) and …

Implicit Memory and Online Advertisement Priming
… Memory research has been investigating the attentional requirements needed for something to be encoded and accessible through implicit memory. So far, previous research has produced mixed results on attentional requirements for perceptual implicit memory, some studies citing evidence for the …

The Influence of Time Pressure and Information Load on Rule-Based Decision-Making Performance
… have been attributed to attempts to reduce attentional demands and to the limitations of working memory. Do these same mistakes occur when little or no demand is placed on working memory and the decision is made by following a set of simple rules? Using a simulation of a radar operator's …

The perceived urgency and detection time of multi-tone and frequency-modulated warning signals in broadband noise
… a loading task which presented additional attentional demands upon the subject during the signal detection task. Free-modulus magnitude estimation quantified the relationship between auditory signal parameters and changes in perceived urgency. The method of paired comparisons was used to …

What's in a game: Examining the effect of video game experience across reading and attentional domains
… understood. In this thesis, we evaluate whether attentional processes may be a driving force behind the relationship between reading and video game experience. We additionally examined lexical and sublexical processing more precisely than previous studies by using exception words to encourage …

Language, thought and deafness : conceptual and methodological issues, with reference to visual-spatial processing, control of attention and sign language
… of task and information characteristics, attentional demands of the stimuli and social factors; the presence of a deaf experimenter improved problem solving performance for concrete problems. The results were discussed with reference to Sign language, and its ability to represent …

Maturation of Speech Discrimination and Attentional Requirements in Late Childhood
… development is characterized by shifts from an attentionally demanding mode of processing speech sounds to one that occurs relatively automatically, the specific developmental time-course of these changes remains unclear. The present work reports the findings of two experiments that aimed to …

Cognitive-motor interaction in health and disability
