ABSTRACT Mind‐wandering (MW) refers to the shift of attention away from an ongoing task and/or external environment towards mental contents (e.g., memories, prospective thoughts) unrelated task. Physiological measures pupil size, EEG, and fMRI) have often been acquired as objective markers for MW states, which has greatly helped their study well triangulation with other measures. Pupillometry in particular used a covert biomarker because it is reliably modulated by several distinct processes spanning arousal, emotion, attention, signals attentional lapses. Yet, coupling measurement size led seemingly contrasting results. We argue that, common studies reviewed here, one reason resolving tonic reflects low‐frequency, slow changes one's physiological state, thus implicitly assumes that static, long‐lasting process. then additionally focus on three major axes variability studies: (i) definition MW; (ii) impact contextual aspects, such demands individual arousal levels; (iii) identification tracking combination pupillary provide overview these differences put forward recommendations using measures—including, but not limited to, size—in research effectively. In conclusion, pupillometry can be very informative tool research, provided due methodological caution.

Pupil size is modulated by various cognitive factors such as attention, working memory, mental imagery, and subjective perception. Previous studies examining effects on pupil mainly focused inducing or enhancing a experience of brightness darkness (for example asking participants to attend to/memorize bright dark stimulus), then showing that this affects size. Surprisingly, the inverse has never been done; is, it still unknown what happens when eliminated strongly reduced even though stimuli are physically present. Here, we aim answer question using perceptual fading, phenomenon where visual stimulus gradually fades from awareness despite its continuous presentation. The study contains two blocks: Fading Non-Fading. In block, were presented with black white patches fuzzy outline at same location throughout thus strong fading. contrast, in Non-Fading switched sides each trial, preventing Participants covertly attended one patches, indicated cue, reported offset set circles displayed top. We hypothesized will be covert attention but effect not (or lesser extent) arise block. found bright/dark does modulate during fading (Fading block), extent than brightness/darkness preserved (Non-Fading block). This implies always decreases decreases. broader terms, suggests modulations reflect mixture high-level lower-level processing.

Pupil diameter, controlled by the autonomic nervous system (ANS), reflects numerous processes, from arousal to cognitive functions. In particular, characteristics of pupil at rest, its size and dynamics, reflect tonic activity ANS. However, which factor can influence these pupillary rest remains unclear. has been shown have a physiological, rhythmic oscillatory called hippus is naturally occurring in children adults still poorly characterised. Our aim better characterise investigating how parameters are influenced different bottom-up (illumination) top-down (cognitive load) conditions. Thirty were included study (19-35 years old). order disentangle illumination load, we recorded variations during 5 randomly appearing blocks. For each block, participant had fixate central cross. The blocks varied according gradients (11 lux, 19 lux 28 lux) load (fixation, dot counting mental subtraction). Three main assessed: median frequency amplitude hippus. We observed clear differences between illumination, decreased when increased. conditions, high led greater dilation frequency. Overall, processing differently, probably through shared integrative structures like locus coeruleus superior colliculus.
