“…It was found that, although both tasks yielded reliable accuracy measures, heartbeat counting scores were unrelated to heartbeat detection scores in this sample of university students. This evidence adds to previous findings that heartbeat counting scores are uncorrelated with heartbeat detection scores on two‐alternative forced‐choice tasks (Forkmann et al, ; Kandasamy et al, ; Knoll & Hodapp, ; Phillips et al, ; Schulz et al, ; Weisz et al, ).…”

“…Thus, cases for the validity of both the HBC and six‐interval HBD measures have been presented by proponents of these methods while questions of their validity have been raised by critics of each of the methods. Some investigators have reported that performance on the HBC task is related to HBD performance on two‐alternative forced‐choice tasks (Hart, McGowan, Minati, & Critchley, ; Knoll & Hodapp, ), but others have found performance on the two tasks to be uncorrelated (Forkmann et al, ; Kandasamy et al, ; Phillips et al, ; Schulz, Lass‐Hennemann, Sutterlin, Schachinger, & Vogele, ; Weisz et al, ), also see Knoll & Hodapp () . In this context, the current experiment was undertaken in order to clarify the extent to which the HBC task (Schandry, ) and the six‐interval HBD task (Brener et al, ) measure the same or different abilities.…”

Heartbeat counting is unrelated to heartbeat detection: A comparison of methods to quantify interoception

Recent research has identified individual differences in interoceptive sensitivity as a key source of variation in action, cognition, and emotion. This research has relied heavily on a single method for assessing interoceptive sensitivity: the accuracy of counting heartbeats while at rest. The validity of this method was assessed here by comparing the heartbeat counting (HBC) performance of 48 individuals with their heartbeat detection (HBD) performance. The HBC task required participants to report the numbers of heartbeats counted during brief signaled periods and indexed cardioceptive accuracy by the difference between the numbers of reported and actual heartbeats. In the HBD task, participants indicated the temporal location of heartbeat sensations relative to the onset of ventricular contraction. On each trial, they judged whether heartbeat sensations were or were not simultaneous with brief tones presented at one of six fixed delays following R waves of the ECG. In this method, cardioceptive accuracy or precision was indexed by variability in the temporal locations, relative to the R wave, of tones judged to be simultaneous with heartbeat sensations. Although intratask correlations indicated that each method yielded reliable scores, intertask correlations showed that HBC scores were unrelated to HBD scores. These results, which indicate that heartbeat detection and heartbeat counting are distinct processes, raise important questions about the assessment of interoceptive sensitivity and the involvement of this attribute in the psychological processes that have been associated with it on the basis of their correlations with HBC performance.

“…A directional one‐tailed parametric correlation revealed a significant relationship between the two variables ( r = .477; p = .019) . To explore this effect further and given the relatively small sample size for correlation analyses, we followed the rationale set out in Kandasamy et al, , p. 3, creating groups with different levels of dance expertise. A median split was performed on the variable years of dance experience (median = 17.5; range: 8–30 years).…”

I can feel my heartbeat: Dancers have increased interoceptive accuracy

Interoception is the process of perceiving afferent signals arising from within the body including heart rate (HR), gastric signals, etc., and has been described as a mechanism crucially involved in the creation of self-awareness and selfhood. The heartbeat perception task is a tool to measure individuals' interoceptive accuracy (IAcc). IAcc correlates positively with measures of self-awareness and with attributes including emotional sensitivity, empathy, prosocial behavior, and efficient decision making. IAcc is only moderate in the general population, and attempts to identify groups of people who might have higher IAcc due to their specific training (e.g., yoga, meditation) have not been successful. However, a recent study with musicians suggests that those trained in the arts might exhibit high IAcc. Here, we tested IAcc in 20 professional dancers and 20 female control participants on a heartbeat perception task. Dancers had a higher IAcc, and this effect was independent of their lower heart rates (a proxy measure of physical fitness), counting ability, and knowledge about HR. An additional between-groups analysis after a median split in the dancer group (based on years of dance experience) showed that junior dancers' IAcc differed from controls, and senior dancers' IAcc was higher than both junior dancers and controls. General art experience correlated positively with IAcc. No correlations were found between IAcc and questionnaire measures of empathy, emotional experience, and alexithymia. These findings are discussed in the context of current theories of interoception and emotion-highlighting the features of arts training that might be related to IAcc.

“…First, as interoception is linked to risk-taking and advantageous decision-making (Werner et al, 2009; Kandasamy et al, 2016), we predicted that individual differences in interoceptive sensibility would predict risk-taking. Second, extending earlier observations (Tice et al, 2001), we predicted that negative emotional states compromise self-control, and thus increase behavioral impulsivity.…”

Objectives: The consequences of impulsive decisions and actions represent a major source of concern to the health and well-being of individuals and society. It is, therefore, crucial to understand the factors which contribute to impulsive behaviors. Here, we examined how personality traits of behavioral tendencies, interoceptive sensibility as well as transient mood states predict behavioral performance on impulsivity and risk-taking tasks.Method: 574 (121 males; age 18–45) individuals completed self-report personality measures of impulsivity, reward sensitivity, punishment avoidance as well as interoceptive sensibility, undertook a mood assessment and performed a set of cognitive tasks: delay discounting (temporal impulsivity), probability discounting (risk-taking), and reflection impulsivity task. Data were interrogated using principal component analysis, correlations and regression analyses to test mutual relationships between personality traits, interoceptive sensibility, mood state and impulsive behaviors.Results: We observed a clear separation of measures used, both trait and behavioral. Namely, sensation-seeking, reward sensitivity and probability discounting reflected risk-taking. These were separate from measures associated with impulsivity, both trait (negative and positive urgency, premeditation, perseverance) and behavioral (delayed discounting and reflection impulsivity). This separation was further highlighted by their relationship with the current emotional state: positive affect was associated with increased risk-taking tendencies and risky decision-making, while negative emotions were related to heightened impulsivity measures. Interoceptive sensibility was only associated with negative emotions component.Conclusion: Our findings support the proposal that risk-taking and impulsivity represent distinct constructs that are differentially affected by current mood states. This novel insight enhances our understanding of impulsive behaviors.
