“…Furthermore regarding common characteristics, AP possessors have shown to exhibit more autistic traits (Brown et al 2003;Dohn et al 2012;Wenhart, Bethlehem, et al 2019) and rather an "autistic-typical" cognitive style, namely the processing of local information in expense of global ones (Mottron et al 2000;Foxton et al 2003), which is observable not only in the auditory but also in the visual domain (Costa-Giomi et al 2001;Chin 2003;Ziv and Radin 2014;Wenhart, Hwang, et al 2019). As another overlapping feature, imaging studies pointed out that specific hyperfunctioning, such in the cases of AP, synesthesia or other savant skills, local hyperconnectivity between the involved brain areas often underlies (Hänggi et al 2008;Loui et al 2010;Jäncke, Langer, et al 2012;Mottron et al 2013;Elmer et al 2015;Brauchli et al 2019). A similar phenomenon to the AP-specific aversion confirmed in this study has been described in congenital synesthesia, a condition that overlaps phenotypically and genotypically with AP (Loui et al 2012a;Gregersen et al 2013) and also co-occurs with autism (Mottron et al 2013;Neufeld et al 2013;Bouvet et al 2014).…”

Absolute pitch (AP) refers to the ability of identifying the pitch of a given tone without reliance on any reference pitch. The downside of possessing AP may be the experience of disturbance when exposed to out-of-tune tones. Here, we investigated this so-far unexplored phenomenon in AP, which we refer to as auditory aversion. Electroencephalography (EEG) was recorded in a sample of AP possessors and matched control musicians without AP while letting them perform a task underlying a so-called affective priming paradigm: Participants judged valenced pictures preceded by musical primes as quickly and accurately as possible. The primes were bimodal, presented as tones in combination with visual notations that either matched or mismatched the actually presented tone. Regardless of the prime condition, AP possessors performed more poorly in judging pleasant pictures and their EEG revealed later peaks at around 200 ms (P200) after prime onset. Their performance dropped when responding to pleasant pictures preceded by incongruent primes, especially when mistuned by one semitone.This interference was also reflected in an EEG deflection at around 400 ms (N400) after picture onset, preceding the behavior responses. These findings suggest that AP possessors process mistuned musical stimuli and pleasant pictures as affectively unrelated with each other, supporting an aversion towards out-of-tune tones in AP possessors. The longer prime-related P200 latencies exhibited by AP possessors suggest a delay in integrating musical stimuli, underlying an altered affinity towards pitch-label associations.

Dissociating refreshing and elaboration and their impacts on memory

Maintenance of information in working memory (WM) is assumed to rely on refreshing and elaboration, but clear mechanistic descriptions of these cognitive processes are lacking, and it is unclear whether they are simply two labels for the same process. This fMRI study investigated the extent to which refreshing, elaboration, and repeating of items in WM are distinct neural processes with dissociable behavioral outcomes in WM and long-term memory (LTM). Multivariate pattern analyses of fMRI data revealed differentiable neural signatures for these processes, which we also replicated in an independent sample of older adults. In some cases, the degree of neural separation within an individual predicted their memory performance. Elaboration improved LTM, but not WM, and this benefit increased as its neural signature became more distinct from repetition. Refreshing had no impact on LTM, but did improve WM, although the neural discrimination of this process was not predictive of the degree of improvement. These results demonstrate that refreshing and elaboration are separate processes that differently contribute to memory performance.

“…Previous studies on brain function in AP and non-AP musicians found evidence for alterations in sensory and higher-order brain regions. Regarding the former, there is evidence for enhanced neural responses in AP in Heschl's gyrus and the planum temporale during acoustic stimulation (Wengenroth et al, 2014;Leipold et al, 2019) and altered connectivity patterns in Heschl's gyrus during rest (Brauchli et al, 2019). In addition, the planum polare, which is part of the auditory association cortex and located immediately anterior to Heschl's gyrus, has recently been implicated in AP (Kim and Knösche, 2017).…”
