Event-related potentials and performance of attention-deficit hyperactivity disorder: Children and normal controls in auditory and visual selective attention tasks

Heritability of anterior and posterior visual N1

“…It is possible that more consistent effects may be found in the 'processing negativity', which is the negative shift seen in a selective attention task by comparing ERPs of stimuli from the attended to those of the unattended channel, appearing in a time range covering the N1, P1 and N2 (Altenmüller and Gerloff, 1999). Recently, it has indeed been reported that ADHD patients have a reduced processing negativity in an auditory selective attention task (Jonkman et al, 1997;Kenemans et al, 2005).…”

The Effects of a Sub-Anaesthetic Dose of Ketamine on Human Selective Attention

“…The selective attention task (see also Jonkman et al 1997) consisted of 300 stimuli presented in such a way that they randomly were perceived in either the right or the left ear. Two types of stimuli could be distinguished: standard tones, which appeared in 80%x of the cases, and deviant tones, which appeared in the resulting 20% of the cases.…”

“…All three ERP-components mentioned above can be measured in a special kind of auditory oddball task, the so called selective attention task (Jonkman et al 1997;Näätänen 1990;Näätänen et al 1993;Sams et al 1985;. In this task, usually two types of auditory stimuli are presented to the left and right ear: a frequently appearing standard stimulus and an occasionally appearing deviant stimulus.…”

No effects of l-dopa and bromocriptine on psychophysiological parameters of human selective attention

“…This resulted in a more difficult task in experiment I when compared to experiment II. The auditory selective attention task (see also : Jonkman et al, 1997;Oranje et al, 2000) consisted of 300 stimuli, presented randomly in either the right or the left ear. Two types of stimuli were used: standard tones, which appeared in 80% of the cases, and deviant tones, which appeared in the remaining 20% of the cases.…”
