The formal sector in South Africa is unable to provide adequate employment for labour although the economy registered positive economic growth rates over the past 15 years since the demise of apartheid. This is a critical problem, given the current r

ERPs were recorded during several RT tasks: simple RT; oddball choice RT; a LIE condition in which subjects were told stimuli would infrequently change, but did not; differential responding to two equiprobable stimuli that were randomized in one cond

The topography of averaged ERP to auditory and visual stimuli was evaluated employing an array of scalp electrodes overlying the left hemicranium in a sequential discrimination (Go-NoGo) task. The discriminanda (S1 and S2) were presented 1 sec apart

Averaged visual evoked potentials to sequentially flashed words comprising a sentence were recorded from vertex and left and right temporoparietal electrodes in 8 right-handed subjects. In condition 1 the sentence took the form: The -eel is on the sh

Averaged evoked potentials were recorded from PZ and left and right temporo-parietal electodes to real speech words and human sounds in 8 right-handed subjects. Stimuli were presented in a "no task" condition where the subject was instructed to liste

Event-related potentials were recorded during simple reaction time and 3 discrimination conditions which varied in the amount of stimulus information that needed to be processed. It was found that NA became longer in duration as the amount of stimulu

Event-related potentials were studied while subjects performed physical and semantic discrimination tasks. Two negative components, NA and N2, were observed in both kinds of discriminations. The earlier component, NA, had a constant onset latency, bu

Averaged evoked responses to auditory stimuli were obtained in simple reaction time and vigilance tasks, as well as a no response control condition. The P2 component of sensory evoked potentials had essentially identical peak latency for the various

Event-related potentials (ERPs) were obtained to letters during 3 tasks that involved a SIMPLE RESPONSE (SR) to each letter presentation, a FORM discrimination of the letters that formed a closed loop, and a RHYME discrimination of the letters that r

Publisher Summary In relating scalp-recorded event-related potentials (ERPs) to underlying brain activity on the one hand and psychological processes on the other, a key issue is the definition of ERP components. It is often assumed that the voltage
