“…Future research could examine whether the functional coupling of the sensorium with quiescent periods of the cardiovascular system interacts with different levels of conscious interoceptive inferences. To this aim, further work could examine how active sensing unfolds in individuals who sense, interpret, and integrate to a different extent signals originating from within the body (e.g., interoceptive sensibility; e.g., Galvez-Pol et al, 2021 ; Garfinkel et al, 2015 ; Palser et al, 2018 ; Suksasilp and Garfinkel, 2022 ). Likewise, future work in active sensing may include the co-registration of neuronal and physiological recordings.…”

Perception and cognition are modulated by the phase of the cardiac signal in which the stimuli are presented. This has been shown by locking the presentation of stimuli to distinct cardiac phases. However, in everyday life sensory information is not presented in this passive and phase-locked manner, instead we actively move and control our sensors to perceive the world. Whether active sensing is coupled and modulated with the cardiac cycle remains largely unknown. Here we recorded the electrocardiograms of human participants while they actively performed a tactile grating orientation task. We show that the duration of subjects' touch varied as a function of the cardiac phase in which they initiated it. Touches initiated in the systole phase were held for longer periods of time than touches initiated in the diastole phase. This effect was most pronounced when elongating the duration of the touches to sense the most difficult gratings. Conversely, while touches in the control condition were coupled to the cardiac cycle, their length did not vary as a function of the phase in which these were initiated. Our results reveal that we actively spend more time sensing during systole periods, the cardiac phase associated with lower perceptual sensitivity (vs. diastole). In line with interoceptive inference accounts, these results indicate that we actively adjust the acquisition of sense data to our internal bodily cycles.

“…In order to address our specific research questions regarding the characteristics (i.e., diffusion, size, intensity, clarity, and congruency) of emotional embodiment across schizotypy dimensions, we extracted several metrics from the EmBODY data. These methods were adapted from previous body mapping studies ( Nummenmaa et al, 2014 ; Sachs et al, 2019 ; Torregrossa et al, 2019b ; Galvez-Pol et al, 2021 ; Lloyd et al, 2021 ). In addition, we implemented a new metric to quantify the spatial spread of embodied sensations that we termed the diffusion metric .…”

“…To assess the size of bodily sensations, the proportion of the body colored for each emotion was computed ( Galvez-Pol et al, 2021 ; Lloyd et al, 2021 ). Specifically, the number of non-zero pixels (i.e., colored pixels) was divided by the total number of pixels (50,364) for each participant, for each emotion.…”

BackgroundDisembodiment and socio-emotional deficits are core features of the schizophrenia spectrum from the prodromal stages to chronic illness. A recent study documented anomalous emotional embodiment in individuals with schizophrenia. Although bodily self disturbances have been shown to precede and predict psychosis onset in at-risk populations, the etiology of anomalous emotional embodiment remains largely unexplored. The present study investigated bodily maps of emotions in relation to schizotypy to extend our understanding of embodied emotions in the schizophrenia spectrum.MethodsA total of 419 participants (312 female; 19.50 ± 1.22 years) completed a topographical body mapping task where they reported patterns of embodiment experienced in the context of eleven different emotions and a neutral state (EmBODY). Embodied emotions were investigated in relation to multidimensional schizotypy.ResultsIndividuals with elevated negative schizotypy experienced embodied emotions with higher intensity (r = 0.16, p = 0.003) but lower clarity (i.e., endorsing activation and deactivation in the same bodily location; β = −0.28, 95% CI [−0.54, −0.03], Z = 2.25, p=0.02) and endorsed more incongruent bodily sensations of emotions (i.e., reporting bodily activation in the context of a low-arousal emotion, r = 0.12, p = 0.05; reporting bodily deactivation in the context of high-arousal emotions, r = 0.13, p = 0.02). In line with the anomalous emotional embodiment documented in individuals with schizophrenia, some of these differences were particularly notable for low-arousal emotions.DiscussionThese results reveal negative schizotypy as a significant correlate of differences in emotional embodiment. More work is needed to link these differences to the anomalous bodily sensations of emotions documented in schizophrenia and assess their functional impact.

Perception and cognition are modulated by the phase of the cardiac signal in which the stimuli are presented. This has been shown by locking the presentation of stimuli to distinct cardiac phases. However, in everyday life sensory information is not presented in this phase-locked and passive manner, instead we actively sample the world. Whether active sensing is coupled and modulated with the cardiac cycle remains largely unknown. Here we recorded the ECGs of human participants while they actively performed a tactile grating orientation task. Here we show that the duration of subjects' touch varied as a function of the cardiac phase in which they initiated it. Touches initiated in the systolic phase of the cardiac cycle were held for longer periods of time than touches initiated in the diastolic phase. This effect was driven by the elongation of their holds to sample the most difficult gratings. Conversely, while touches in the control condition were coupled to the cardiac cycle, their length was not modulated as a function of when in the cycle these were initiated. In line with interoceptive inference accounts, these results are consistent with the hypotheses that we actively adjust our sensory sampling so that we spend more time in the diastole period of the cardiac cycle in which perceptual sensory sensitivity is greatest.
