Measuring Pavlovian appetitive conditioning in humans with the postauricular reflex
Abstract
Despite its evolutionary and clinical significance, appetitive conditioning has been rarely investigated in humans. It has been proposed that this discrepancy might stem from the difficulty in finding suitable appetitive stimuli that elicit strong physiological responses. However, this might also be due to a possible lack of sensitivity of the psychophysiological measures commonly used to index human appetitive conditioning. Here, we investigated whether the postauricular reflex—a vestigial muscle microreflex that is potentiated by pleasant stimuli relative to neutral and unpleasant stimuli—may provide a valid...

Toward a better noninvasive assessment of preejection period: A novel automatic algorithm for B ‐point detection and correction on thoracic impedance cardiogram
Abstract
Impedance cardiography is the most common clinically validated, noninvasive method for determining the timing of the opening of the aortic valve, an important event used for measuring preejection period, which reflects sympathetic beta‐adrenergic influences on the heart. Automatic detection of the exact time of the opening of the aortic valve (B point on the impedance cardiogram) has proven to be challenging as its appearance varies between and within individuals and may manifest as a reversal, inflection, or rapid slope change of the thoracic impedance derivative's (dZ/dt) rapid rise. Here, a novel automatic al...

Cardiac measures of nuclear power plant operator stress during simulated incident and accident scenarios
Abstract
Maintaining optimal performance in demanding situations is challenged by stress‐induced alterations in performance. Here, we quantified the stress of nuclear power plant (NPP) operators (N = 20) during a full‐scale simulator training for incident and accident scenarios. We compared the ambulatory electrocardiography measurements of heart rate (HR) and heart rate variability (HRV), and self‐reported stress during baselines and simulated scenarios. Perceived (scale 0–10) and physiologically measured stress were low during baseline after the scenarios and normal NPP operation (means 1.8–2.2, mean HR 75...

Event ‐related potentials of emotional and neutral memories: The role of encoding position and delayed testing
Abstract
Previous research found that memory is not only better for emotional information but also for neutral information that has been encoded in the context of an emotional event. In the present ERP study, we investigated two factors that may influence memory for neutral and emotional items: temporal proximity between emotional and neutral items during encoding, and retention interval (immediate vs. delayed). Forty‐nine female participants incidentally encoded 36 unpleasant and 108 neutral pictures (36 neutral pictures preceded an unpleasant picture, 36 followed an unpleasant picture, and 36 neutral pictures were prec...

Loser! On the combined impact of emotional and person ‐descriptive word meanings in communicative situations
Abstract
Humans have a unique capacity to induce intense emotional states in others by simple acts of verbal communication, and simple messages such as bad can elicit strong emotions in the addressee. However, up to now, research has mainly focused on general emotional meaning aspects and paradigms of low personal relevance (e.g., word reading), thereby possibly underestimating the impact of verbal emotion. In the present study, we recorded ERPs while presenting emotional words differing in word‐inherent person descriptiveness (in that they may or may not refer to or describe a person; e.g., winner vs. sunflower). We pre...
