Abstract The experiment reported here was aimed at determining whether the level of brain activity can be related to performance in trained subjects. Two tasks were compared: a temporal and a linguistic task. An array of four letters appeared on a screen. ...
Abstract Mild head injury can result in the development of persistent symptoms including impairments of memory and attention in a small but significant minority. The problem in assessing these difficulties in such cases is the likely interaction of ...
Abstract Previous research has suggested a possible link between the effects of scopolamine-induced muscarinic cholinergic receptor blockade on memory and its effect on auditory P3 amplitude and latency. A potential problem with this hypothesis is that, ...
The use of mobile phones has been shown to increase drivers' reaction times (RTs), but whether this results from interference with attention, stimulus identification, or response production remains unclear. We recorded RTs and event-related brain ...
Abstract Two experiments were conducted to assess simultaneously the effects of attentional and emotional processes on startle eyeblink modulation. In each experiment, participants were presented with a pleasant and an unpleasant picture. Half the ...
Abstract In the present study we explored the focusing of visuospatial attention in subjects practicing and not practicing activities with high attentional demands. Similar to the studies of Castiello and Umiltà (e. g., 1990), our experimental procedure ...
Abstract After a hint from Lang et al.'s (1997) defence cascade, researchers considered cognitive process experienced when encountering mental stress to be composed of four elements: (serially) first attention (Attent), second unpleasant affect (UnplAff) ...
Abstract The effects of attention to a lead stimulus and of its sensory properties on modulation of the acoustic blink reflex were investigated. Participants performed a reaction time task cued by an acoustic or a visual lead stimulus. In Experiment 1, ...
Abstract: Event-related potentials (ERPs) were recorded from 24 subjects in a visual selective-attention task in which two words were each presented both in a prime display and in a probe display with the target word defined by color. Subjects' task for ...
Abstract: Previous research has found that pain can exert a disruptive effect on cognitive processing. This experiment was conducted to extend previous research with participants with chronic pain. This report examines pain's effects on early processing ...
This study combined an individual differences approach to interrogative suggestibility (IS) with ERP recordings to examine two alternative hypotheses regarding the source of individual differences in IS: (1) differences in attention to task-relevant vis-à-...
The question of whether the mismatch negativity (MMN) is modulated by attention has been debated for over a decade. Although the MMN is widely regarded as reflecting a preattentive auditory process, many studies have shown attention effects on MMN. So, ...
The mismatch negativity (MMN) is an event-related brain potential elicited by the occurrence of a rare event (deviance) in an otherwise regular acoustic environment, and is assumed to reflect a preattentive mechanism for change detection. A widely adopted ...
The visual homolog of the (auditory) mismatch negativity, the vMMN, has already been reviewed (Pazo-Alvarez, Cadaveira, & Amenedo, 2003), but a considerable body of more recent research exists. The present paper concentrates on two crucial issues of vMMN ...
In the present study, we used event-related potentials (ERPs) and behavioral measurements in a peripherally cued line-orientation discrimination task to investigate the underlying mechanisms of orienting and focusing in voluntary and involuntary attention ...
Performance outcomes, such as the distance rowed or run, can be influenced by the type of attentional focus an individual adopts. The present study tested how attentional focus during a weight training exercise influenced a direct measure of performance ...
Frequency-domain techniques describe oscillations as a fundamental behavior of neurons and brain signals. Oscillations synchronize over large portions of cortex and mediate in the spatiotemporally coherent activation of neuron assemblies required for ...
The paired-click paradigm (PCP) is widely used to study sensory habituation or gating in a number of psychiatric and neurological conditions. The classic paradigm does not control for attentional factors. In order to assess the influences of incorporating ...
The current study was an attempt to determine the degree to which the suppression of respiratory sinus arrhythmia (RSA) and attentional control were influential in the ability to engage various executive processes under high and low levels of negative ...
