Helen Y. Weng
First appears as lead author of Weng et al. (2021), and gets a page rather than co-author treatment for two reasons: she is first author of the framework itself, and her methodological line answers a problem this wiki has been complaining about since its early ingests.
The measurement contribution
The wiki’s recurring difficulty is that interoceptive attention can only be assessed by asking (questionnaires such as the maia, vulnerable to belief and demand) or by cardiac tasks whose validity is itself a live debate. Weng’s decoding approach is a third option: train participant-specific classifiers on brain states corresponding to interoception, mind-wandering and self-referential processing, then use them to estimate what a meditator’s attention is doing, continuously, without a probe.
Two things follow that the wiki should hold:
- It gives experience sampling during meditation a neural analogue — see experience-sampling — and produces a quantity (“percentage time of interoceptive focus”) that no self-report instrument can deliver.
- Orienting interoceptive attention to different body locations (breath vs feet) is decodable, which makes attentional topography an empirical question rather than an instruction. That bears on bodily-sensation-maps and on the topographic claims made by MABT.
The caveat is the ordinary one for decoding work and the wiki has no primary source to check it against: classifiers are participant-specific, and what they decode is defined by the training states the experimenter labelled.
Position
Weng is squarely inside the contemplative-neuroscience tradition the wiki already holds through Farb, Lutz and Davidson — her review’s meditation section cites Farb et al. 2013 and Lutz et al. 2008 as load-bearing evidence. What distinguishes her framing is the refusal to treat contemplative training as the interoceptive intervention: it appears in her Figure 1 as one of three levels, next to a nerve stimulator and a breathing pacer, with the explicit suggestion that they be combined. That is an unusually ecumenical position for the field and it is the reason bioelectronic-medicine and mindfulness-interoceptive-training now cross-reference each other.
She is also the source of one of the wiki’s few positive specificity results, reported in her review from her co-author’s trial rather than her own: mindfulness beat slow breathing on sympathetic outcomes despite the meditation producing slow breathing (Park et al. 2014).
