Motor learning can be monitored by observing the development of neural correlates of error processing. Among these neural correlates, the error- and feedback-related negativity (Ne/ERN and FRN) represent error processing mechanisms. While the Ne/ERN is more related to error prediction, the FRN is found after an error is manifested. The questions the current study strives to answer are: What information is needed by the system to make error predictions and how is this represented by the Ne/ERN and FRN in a complex motor task? We reduced the information and increased the difficulty level for the prediction in a semivirtual throwing task and found no Ne/ERN but a large FRN when the action result was finally observed (hitting or missing a target). We assume that uncertainty for error prediction was too high (either due to insufficient information or due to lacking prerequisites for prediction), such that error processing had to be mainly based on feedback. The finding is in line with the reinforcement theory of learning, after which Ne/ERN and FRN should behave complementary.

The purpose of the current study was to examine the relationship between motor ability and response inhibition using behavioral and electrophysiological indices in children with ADHD. A total of 32 participants were recruited and underwent a motor ability assessment by administering the Basic Motor Ability Test-Revised (BMAT) as well as the Go/No-Go task and event-related potential (ERP) measurements at the same time. The results indicated that the BMAT scores were positively associated with the behavioral and ERP measures. Specifically, the BMAT average score was associated with a faster reaction time and higher accuracy, whereas higher BMAT subset scores predicted a shorter P3 latency in the Go condition. Although the association between the BMAT average score and the No-Go accuracy was limited, higher BMAT average and subset scores predicted a shorter N2 and P3 latency and a larger P3 amplitude in the No-Go condition. These findings suggest that motor abilities may play roles that benefit the cognitive performance of ADHD children.

Latencies and peak-to-peak amplitudes of pattern-reversal evoked-potential (PREP) components of active and inactive community-dwelling healthy 61- to 77-year-olds were compared with those of active and inactive 18- to 31-year-olds to determine whether long-term physical activity involvement was associated with attenuation of age-related changes in sensory processes. Binocular PREPs were derived for each of 2 check sizes (22 × 15 ft and 41 × 30 ft of visual angle) to provide increasing challenge of spatial resolution. Analyses of the latencies revealed significant effects for age, gender, and check size such that latencies were longer for older than for young participants, men than for women, and small than for larger check sizes. Amplitudes were larger in older adults for the P100-N150 peak-to-peak difference, but physical activity history was not associated with reduction of the observed age-related increases in component latencies and amplitude. As such, physical activity does not appear to attenuate age-related decline in visual sensory processing.

Alzheimer’s disease (AD) is a neurodegenerative disorder, characterized by a gradual decline in numerous cognitive processes and altered cortical activity. 1 Indeed, the development of AD is usually accompanied by systematic changes in various cortical event-related potentials. In this population

This study investigated the effect of hand movements on behavioral and electro-physiological parameters of saccade preparation. While event-related potentials were recorded in 17 subjects, they performed saccades to a visual target either together with a hand movement in the same direction, a hand movement in the opposite direction, a hand movement to a third, independent direction, or without any accompanying hand movements. Saccade latencies increased with any kind of accompanying hand movement. Both saccade and manual latencies were largest when both movements aimed at opposite directions. In contrast, saccade-related potentials indicating preparatory activity were mainly affected by hand movements in the same direction. The data suggest that concomitant hand movements interfere with saccade preparation, particularly when the two movements involve motor preparations that access the same visual stimulus. This indicates that saccade preparation is continually informed about hand movement preparation.

We used the event-related potential (ERP) methodology to examine differences in neural processing between visually and memory-guided reaches. Consistent with previous findings (e.g., Westwood, Heath, & Roy, 2003), memory-guided reaches undershot veridical target location to a greater extent than their visually guided counterparts. Analysis of the ERP data revealed that memory-guided reaches were associated with reduced potentials over medial-frontal cortex at target presentation and following movement onset. Further, we found that the amplitudes of the potentials over medial-frontal cortex for visually and memory-guided reaches were significantly correlated with the peak accelerations and decelerations of the reaching movements. Our results suggest that memory-guided reaches are mediated by a motor plan that is generated while a target is visible, and then stored in memory until needed—a result counter to recent behavioral theories asserting that memory-guided reaches are planned just before movement onset via a stored, sensory-based target representation.

Motor readiness, visual attention, and reaction time (RT) were assessed in 15 elite table tennis players (TTP) and 15 controls (C) during Posner’s cued attention task. Lateralized readiness potentials (LRP) were derived from contingent negative variation (CNV) at Sites C3 and C4, elicited between presentation of directional cueing (S1) and the appearance of the imperative stimulus (S2), to assess preparation for hand movement while P1 and N1 component amplitudes were derived from occipital event-related potentials (ERPs) in response to S2 to assess visual attention. Both groups had faster RT to validly cued stimuli and slower RT to invalidly cued stimuli relative to the RT to neutral stimuli that were not preceded by directional cueing, but the groups did not differ in attention benefit or cost. However, TTP did have faster RT to all imperative stimuli; they maintained superior reactivity to S2 whether preceded by valid, invalid, or neutral warning cues. Although both groups generated LRP in response to the directional cues, TTP generated larger LRP to prepare the corresponding hand for movement to the side of the cued location. TTP also had an inverse cueing effect for N1 amplitude (i.e., amplitude of N1 to the invalid cue > amplitude of N1 to the valid cue) while C visually attended to the expected and unexpected locations equally. It appears that TTP preserve superior reactivity to stimuli of uncertain location by employing a compensatory strategy to prepare their motor response to an event associated with high probability, while simultaneously devoting more visual attention to an upcoming event of lower probability.

Although putative mechanisms of these effects were not assessed in this study, it is worth pointing out that previous research has focused on biological mechanisms (eg, brain-derived neurotrophic factor) and changes in underlying psychophysiological responses (eg, event-related potentials). In particular
