Two spatial cueing experiments were conducted to examine the functional significance of lateralized ERP components after cue-onset and to discriminate components related to sensory cue aspects and components related to the direction of attention. In Experiment 1, a simple detection task was presented. In Experiment 2, attentional selection was augmented.(More)
Attentional biases for emotional stimuli and general orienting processes were examined in bipolar disorder, using a modified dot-probe task with a spatial cueing paradigm incorporated in it. Bipolar patients in a euthymic state (i.e., remission), bipolar patients in a mildly depressed state, and non-psychiatric controls participated. General orienting(More)
It is often assumed that when a neutral cue is presented in a spatial cueing task, attention remains at fixation until target onset. We hypothesized that variance in nonspatial attention and switches of attention toward target locations can account for variance in reaction times of neutral trials. Lateralized event-related potentials (ERPs) and changes in(More)
To examine the time course of effects of working memory (WM) load on interference control, ERPs were measured in a combined WM and Stroop task. A WM load of 0, 2, or 4 letters was imposed, and during the maintenance-interval Stroop trials were presented that required participants to classify names of famous people while ignoring faces that were either(More)
BACKGROUND Research in cognitive processes and attitudes in bipolar disorder is scarce and has provided mixed findings, possibly due to differences in current mood state. It is unclear whether alterations in cognitive processes and attitudes are only related to the depressive mood states of bipolar patients or also represent a vulnerability marker for the(More)
In a spatial cueing paradigm it was investigated whether endogenous orienting is sensitive to orienting processes in the previous trial. Specifically, the effect of the previous cue direction, the previous trial type (valid, invalid, neutral, catch) and target alternation effects were studied. Strategic effects were shown as attentional costs and benefits(More)
In this study, we explored whether individual differences in dissociation are related to certain resting electroencephalographic (EEG) parameters. Baseline EEG with eyes open and closed was recorded in an undergraduate sample (N = 67). Cortical power in the alpha range was inversely related to dissociative symptoms as measured by the Dissociative(More)
This study investigated if decreased cognitive control, reflected in response inhibition and working-memory performance, is an underlying mechanism of risky driving in young novice drivers. Thirty-eight participants aged 17 to 25 years old, with less than 1 year of driving experience, completed a simulated drive that included several risky driving measures.(More)
OBJECTIVE It was investigated how speed limit repetition and distraction affect drivers' speed management throughout a road section where the imposed speed limit is not in accordance (too low) with road design. BACKGROUND It is not clear how driving speed evolves and to what degree speed limit repetition is necessary on roads where the imposed speed limit(More)
Distracted driving has received increasing attention in the literature due to potential adverse safety outcomes. An often posed solution to alleviate distraction while driving is hands-free technology. Interference by distraction can occur however at the sensory input (e.g., visual) level, but also at the cognitive level where hands-free technology induces(More)
