Older adults show deficits in tasks of set-shifting. Yet, many underlying cognitive functions are required during such tasks and it is currently unknown which of these mechanisms may be deficient in older age. Here, we investigated this question in a preliminary dataset of 45 young participants (age: 25.2 ± 4.3) and 26 older participants (age: 68.1 ± 5.0) in an EEG-compatible set-shifting paradigm. We were particularly interested in two posterior components: 1) The P300 is a positive component that appears approximately 300 ms to 500 ms after the cue and has a lower amplitude during set-shifti

The Inhibition of Return (IOR) is an orienting mechanism to visual or auditory stimuli. It facilitates visual search in crowded scenes by inhibiting inspection of previously searched locations and promote inspection of previously unsearched locations (Klein, 2000). In general, the reaction time (RT) toward a target is fast when the interval between cue and target is short and slow when the interval between cue and target is long. IOR is identified by the crossover point of the RT towards cued and un-cued targets. Aging (Madden, 2007), stressors (Yu et al., 2015), and auditory stimuli (Tang et
