Abstract

Mental functions are influenced by states of physiological arousal. Afferent neural activity from arterial baroreceptors at systole conveys the strength and timing of individual heartbeats to the brain. We presented words under limited attentional resources time‐locked to different phases of the cardiac cycle, to test a hypothesis that natural baroreceptor stimulation influences detection and subsequent memory of words. We show memory for words presented around systole was decreased relative to words at diastole. The deleterious memory effect of systole was greater for words detected with low confidence and amplified in individuals with low interoceptive sensitivity, as indexed using a heartbeat counting task. Our observations highlight an important cardiovascular channel through which autonomic arousal impacts a cognitive function, an effect mitigated by metacognition (perceptual confidence) and interoceptive sensitivity.

  • The dimensional model of interoception can be extended further to incorporate lower level measures of afferent neural traffic and the preconscious impact of interoceptive signals on sensory processing.

    “This dimensional model of interoception can be extended further to incorporate lower level measures of afferent neural traffic (quantifying afferent signal strength, e.g. through heartbeat evoked potentials [20 ]), and the preconscious impact of interoceptive signals on sensory processing (e.g.modification of startle response [21 ,22] or augmentation of threat processing [23 ,24,25]).”

    From Interoception and emotion. (2017) · cites this paper as [22]

    The paper’s background passage (section labelled Abstract; page unavailable) describes cardiac afferent signals and their effects on perceptual processing, and its Discussion reports an effect of cardiac timing on later word memory. It does not establish the claimed extension of a dimensional model or measure afferent signal strength with heartbeat-evoked potentials; its Results also found no cardiac-timing effect on word detection. The cited paper therefore supports the broader idea that interoceptive signals can affect processing, but not the full claim attributed to it. (LLM, conf=0.82)

  • Word recognition memory is modulated by the timing of visual stimuli with respect to cardiac phase under restricted attention.

    “For example, word recognition memory is modulated by the timing of visual stimuli with respect to cardiac phase under restricted attention [63].”

    From Interoceptive inference, emotion, and the embodied self (2013) · cites this paper as [63]

  • Short-term respiratory afferent signals, like cardiac afferent signals, modify defensive reflexes (notably startle responses) and nasopharyngeal airflow influences processing of affective information.

    “Short-term respiratory afferent signals, like cardiac afferent signals, modify defensive reflexes (notably startle responses [22]) and even nasopharyngeal airflow (an internal, yet mostly exteroceptive, respiratory stimulus) also influences processing of affective information [28 ].”

    From Interoception and emotion. (2017) · cites this paper as [22]

    Citation [22] is attached to the claim about defensive reflexes, notably startle responses; the nasopharyngeal-airflow claim has a separate citation. The paper's introductory passage discusses cardiac timing and the processing of somatosensory stimuli, pain, and emotional faces, while its Discussion reports effects on word memory. Searches for startle and defensive reflexes found no passage addressing those responses. (LLM, conf=0.77)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
