In addition to the electroencephalogram data, we gathered a suite of autonomic response measurements and subjective ratings. We employed multiple linear regression analysis, utilizing autonomic responses and subjective reports as predictors of alpha power. We also subtracted the aperiodic components for better estimation of the power of periodic alpha oscillations. Our results from two separately conducted experiments robustly demonstrated that the combined use of autonomic response measurements and subjective ratings effectively predicted the parietal-occipital periodic alpha power variation across a range of conditions. These predictions were supported by leave-one-participant-out cross-validation and cross-experiment validation, confirming that multiple linear relationships can be generalized to new participants.

The results showed a larger LPP in response to unpleasant, compared to pleasant, contents. However, comparisons across the different emotional contents showed that the concordance between subjective and neural engagement varies depending on the emotional contents of the scenes. Specifically, images of threatening animals were rated high in emotional arousal and prompted the largest LPP in adolescents, while images of sad people and images of mundane activities were rated lower in emotional arousal and prompted the smallest LPP responses. However, adolescents showed significant divergence in their responses to pleasant images depicting food and sport: despite being rated high in emotional arousal, these images elicited relatively small LPPs. These results highlight the challenges of selecting emotional pictures to assess neuroaffective responses to pleasant and unpleasant pictures in adolescents.

In this study, we validated four PPG wearables: three consumer-grade devices (Kyto2935, Schone Rhythm 24, and HeartMath Inner Balance Bluetooth) and one research-grade device (Empatica EmbracePlus, successor to the widely-used but discontinued Empatica E4). All devices were worn simultaneously by 40 healthy participants who underwent conditions commonly used in laboratory research (seated rest, arithmetic task, recovery, slow-paced breathing, a neuropsychological task, posture manipulation by standing up) and encountered in ambulatory-like settings (slow walking and stationary biking), compared against a criterion electrocardiography device, the Vrije Universiteit Ambulatory Monitoring System (VU-AMS). We determined the signal quality, the linear strength through regression analysis, the bias through Bland-Altman analysis, and the measurement error through mean arctangent absolute percentage error for each condition against the criterion device. We found that the research-grade device did not outperform the consumer-grade devices in laboratory conditions. It also showed low agreement with the ECG in ambulatory-like conditions. In general, devices captured HR more accurately than HRV. Finally, conditions that deviated from baseline settings and involved slight to high movement, negatively impacted the agreement between PPG devices and the criterion.

While heart rate (HR) and its variability (HRV) may provide non-invasive proxies of cardiac vagal activity, transcutaneous auricular vagus nerve stimulation (taVNS) has yielded mixed effects, with limited research on right branch stimulation. In a randomized crossover study with 36 healthy participants, we investigated taVNS effects on HR and HRV indexed by SDRR, RMSSD, HF-HRV, and LF/HF ratio. To assess the impact of the stimulation side (left vs. right ear) on cardiovascular indices and interaction with the physiological state, we recorded electrocardiograms in four sessions per person, covering three session phases: baseline, during stimulation (taVNS vs. sham), and post-milkshake consumption with stimulation. First, we found moderate evidence against taVNS affecting HR (BF<sub>10</sub> = 0.21). Second, taVNS decreased HRV (multivariate p = 0.004) independent of physiological state, with strong evidence for RMSSD (BF<sub>10</sub> = 15.11) and HF-HRV (BF<sub>10</sub> = 11.80). Third, taVNS-induced changes were comparable across sides and stronger than sham, indicating consistent cardiovascular effects independent of the stimulation side. We conclude that taVNS reduces HRV as indexed by RMSSD, HF-HRV, and SDRR without altering HR, contradicting the assumption that taVNS per se increases cardiovagal activity as indexed by increased HRV due to stimulating vagal afferents. Instead, our results support the role of vagal afferent activation in arousal.

Findings from non-emotion rapid decision-making studies show humans down-sample and downweight extreme evidence. However, deliberate decision-making may rely on a different attention mode than in rapid decision-making; and extreme emotional stimuli are inherently salient. Given these critical differences, it is imperative to directly examine the deliberate decision-making process about multiple emotional stimuli. In the current study, human participants (N = 33) viewed arrays of faces with expressions ranging from extremely fearful to extremely happy freely with their eye movement tracked. They then decided whether the faces were more fearful or happier on average. In contrast to conclusions drawn from non-emotion and rapid decision-making studies, eye movement measures revealed that participants attentionally sampled extreme emotional evidence more than less extreme evidence. Computational modeling results indicated that even though participants exhibited biased attention distribution, they weighted various emotional evidence equally.

This study examined the association between cardiorespiratory fitness and neurophysiological markers of cognitive control during a task requiring working memory maintenance. Young healthy adults (N = 112) completed a submaximal ergometer test to estimate cardiorespiratory fitness.

We obtained corrugator supercilii and zygomaticus major electromyography (EMG) as objective measures of NA and PA. For the no-regulation condition, upon instruction onset, we observed maintained high corrugator and low zygomaticus EMG reactivity, indicating sustained NA activation. Compared to no-regulation, for the neutralize goal, we observed corrugator reduction starting at 1500 ms after instruction onset and no change in zygomaticus, indicating decreased NA and generation of neutral emotion. For the transform goal, we observed corrugator reduction starting at 1000 ms and zygomaticus increase at 3500 ms after instruction onset, indicating decreased NA and increased PA and generation of positive emotion. Model-fitting analyses showed that the best-fitting trajectory for the transform goal's pattern of change was initial NA reduction that turns into PA increase at 2000 ms.
