Controlling for Acute Caffeine Intake in Cardiovascular Reactivity Research
… a repeated measures study involving hand cold pressor (CP) and memory tasks. Caffeinated and decaffeinated coffee were administered. The following CV indices were acquired during baseline, task, and recovery epochs prior to coffee intake, 30 minutes-, and six hours post-intake: Heart rate (HR), …

Putting the Body Back Together: A Functional Autonomic Model of Interoception
… including a call for more integrative and predictive biomarkers for interoceptive ability. While there is a robust literature purporting to measure interoception, there is also significant research challenging the content validity of the current methodology. Beyond these published …

The Autonomic Correlates of Listening Effort
… phases of experiments tested the multi-layer predictions of motivational intensity theory in relation to effortful listening. The first phase provided empirical evidence for the impact of listening demand on listening effort-driven myocardial sympathetic activation (quantified as pre-ejection …

Multi-sensor signal processing methods for home monitoring of cardiovascular and respiratory diseases
… decompensated heart failure patients based on pre-ejection period changes after a six-minute walk test. These methods can potentially lead to automated wearable system that can predict decompensation beforehand, allowing physicians to intervene accordingly.

A wearable heart monitor at the ear using ballistocardiogram (BCG) and electrocardiogram (ECG) with a nanowatt ECG heartbeat detection circuit
This work presents a wearable heart monitor at the ear that uses the ballistocardiogram (BCG) and the electrocardiogram (ECG) to extract heart rate, stroke volume, and pre-ejection period (PEP) for the application of continuous heart monitoring. Being a natural anchoring point, the ear is …

Attachment and Trauma: A Historical and Empirical Study of the Meaning of Unresolved Loss and Abuse in the Adult Attachment Interview
… occurring indicators of unresolved loss/abuse. Predictive models suggested a psychometric model of unresolved states of mind consisting of a combination of these common indicators, which was weakly predictive of infant disorganised attachment. There was no significant association between …

Effects of Exercise Training on Heart Failure Measured Using Seismocardiography
… a global health focus. The nature of the disease presents with a very high mortality rate. In Canada alone, the average mortality rate is approximately 50% within the first five years of diagnosis [1]. Exercise has now become a common treatment modality for many chronic disease conditions …

The Role of Impulsivity and Reward Reactivity in Gray's Behavioral Activation System: Self-Reported Behavior and Autonomic Response to Reward
… to index BAS activity, with higher scores interpreted as indicating greater BAS activity (e.g., Hundt et al., 2008). However, Beauchaine and colleagues (e.g., Brenner, Beauchaine, & Sylvers, 2005) have challenged this view, noting psychophysiological and neuroimaging evidence showing that …

Valutazione degli effetti dell'esercizio fisico adattato sulla capacità fisica e sulla regolazione cardiocircolatoria in pazienti con sclerosi multipla
… regulation during exercise. The aim of the present investigation was to assess the effectiveness of a six months combined training (CT) - in terms of aerobic capacity, walk and speed ability, balance, fatigue and cardiovascular regulation in response to the muscle metaboreflex recruitment - …

Behavioral Inhibition/Activation and Autonomic Control of the Heart: Extending the Autonomic Flexibility Model
… (e.g., cognitive and emotional) flexibility. The present study aimed to extend the autonomic flexibility model through the inclusion of individual differences in the sensitivity of the independent motivational systems presumed to underlie anxiety and impulsivity, namely the behavioral inhibition …
