“…Lastly, replicating previous findings on the age-related effect of P2 [37, 65, 66], our regression analysis results also showed that age predicted P2 amplitudes at frontal sites. More interestingly, our results delineated the effect of age from the effect of mindfulness on P2 amplitudes: age mainly affected positive (compared to neutral) stimuli (Pos-Neu) at frontal locations, while mindfulness influenced the difference between positive and negative stimuli (Pos-Neg) at frontocentral sites (less anterior).…”

This study explored the relationship of mindfulness trait with the early and late stages of affective processing, by examining the two corresponding ERP components, P2 and LPP, collected from twenty-two male Chinese participants with a wide range of meditation experiences. Multiple regression analyses was performed on the mindfulness scores, as measured by CAMS-R, with the subjective affective ratings and ERP data collected during an emotion processing task. The results showed that increased mindfulness scores predicted increased valence ratings of negative stimuli (less negative), as well as increased P2 amplitudes at the frontocentral location for positive compared to negative stimuli. Based on these findings, a plausible mechanism of mindfulness in reducing negativity bias was discussed. Moreover, our results replicated previous findings on the age-related increase of P2 amplitudes at the frontal sites for positive compared to neutral stimuli. Since the locations at which P2 amplitudes were found as associated with age and mindfulness differed, as did the emotional contents of the stimuli being compared, indicating that the effect of age did not confound our findings on mindfulness and the two factors might operate on early affective processing from distinct sources and mechanisms.

“…Moreover, the enhanced and topographically-different P1 in the Older group might suggest enhanced prestimulus focus on the task, which would be compatible with the investment of greater effort. These interpretations are consistent with the typical view that older adults employ compensatory mechanisms in order to perform satisfactorily (e.g., Friedman et al, 1997;Hong et al, 2014;Hsieh and Fang, 2012;Staub et al, 2014;Vallesi, 2011).…”

“…The frontal negativity of the classic SW has also been reported to be absent in an older group (Pfefferbaum et al, 1980). This type of topographic finding has been interpreted increasingly as evidence for compensatory frontal activity in older compared with younger subjects, used to maintain relatively high performance levels (e.g., Hong et al, 2014;Hsieh and Fang, 2012;Staub et al, 2014;Vallesi, 2011) in the context of reductions in frontal brain volume (Driscoll et al, 2009;Raz et al, 2005).…”

Objective: We recently proposed a sequential processing schema for the equiprobable auditory Go/NoGo task, based on a principal components analysis (PCA) of event-related potentials (ERPs) from a university student sample. Here we sought to replicate the schema, and use it to explore processing in well-functioning older adults. Methods: We compared behavioural responding and ERPs of 20 independent-living older adults (M age = 68.2 years) to data from a sex-and handedness-matched group of university students (M age = 20.4 years). ERPs had substantial latency differences between the groups, and hence were subjected to separate group temporal PCAs. Results: Component latencies were systematically increased in the older group by some 26%, with no significant increase in RT or error rates. Despite some differences in their identified components, each group displayed differential component responsivity to Go versus NoGo; this was reduced in the older participants. Conclusion: The results support our processing schema, and provide insight into the processing stages in well-functioning older adults. Significance: Understanding the perceptual and cognitive processing stages in normal ageing is a pre-requisite for research on mild cognitive impairment and dementia. This study may also provide a simple paradigm and schema suitable for further exploration of functionality in ageing. Highlights• A PCA derived sequential processing Go/NoGo schema was confirmed in young adults, with similar processing in healthy older adults.• Older adults had comparable Go RT and Go/NoGo error rates, increased latencies and smaller, less differentiated Go/NoGo P3s, and N2c was absent.• Go/NoGo processing by Older adults may reflect less specialist processing regions, requiring more effort.

“…These authors viewed this age effect as a deficit in the capacity to withdraw processing resources from irrelevant stimuli at early stages of perceptual analysis, suggesting that P2 amplitude over occipital sites was rather related to bottom-up attentional processing. Regarding the frontally distributed P2, previous studies have already evidenced age-related increases in frontal P2 amplitudes (Amenedo & Diaz, 1999;Anderer, Semlitsch, & Saletu, 1996;Getzmann, Gajewski, & Falkenstein, 2013;Staub et al, 2014b), a component that has been conceptualized as a marker of the activation of top-down attentional control over the processing of task-relevant stimuli (Luck & Hillyard, 1994). Thus, our results suggest that compared to younger adults, older participants allocated more attentional resources to the task at hand, irrespective of its nature.…”

“…In other words, discrepancies regarding the effect of age on sustained attention performance in each approach could be explained by a differential use of automatic and controlled processes as a function of age in a situation of sustained attention. For example, recent results showed that in a long-lasting Go/No-Go sustained attention task, older adults deployed increased levels of attentional control relative to younger subjects (Staub, Doignon-Camus, Bacon, & Bonnefond, 2014b). In order to put this possibility to the test, we employed in the current study two versions of the SART which only differed in their response mode -a TFT version, which mostly relies on automatic processes, and the regular Go/No-Go version, which mostly relies on controlled processes, together with the event-related potentials (ERP) technique, allowing us to examine, in a time on task perspective, the automatic or controlled nature of processing adopted by each group in these tasks.…”
