Averaged ERP waveforms from individual research participants may be greatly distorted by noise, but the field lacks a widely accepted metric of data quality that would allow us to objectively quantify the extent of the noise. Here, we propose such a metric (the Standardized Measurement Error) and show how it is related to effect sizes and statistical power.

The current study assessed the relationship between eye movements and covert attention. We found that the N2pc component—a putative neural index of covert attention—only preceded eye movements under a limited set of conditions, suggesting that not every eye movement is preceded by a shift of covert attention. This finding has important implications regarding the nature of the N2pc component and the relationship between covert and overt attention more generally.

Knowledge on the impact of LSD and its antagonist ketanserin on the human autonomic nervous system is sparse. We show that the subjective effects of LSD are mainly driven by sympathetic activation and can be antagonized by ketanserin‐induced parasympathetic activity. The autonomic parameters further might serve as biomarkers for subjective LSD experiences and potentially as treatment markers, for example, in mood disorders.

The source of heartbeat sensations is an unresolved issue in the study of cardioception. Using a vibrotactile masking paradigm we examined the contribution of somatosensory mechanoreceptors on the ability to detect heartbeat sensations. Our findings argue that somatosensory Pacinian and non‐Pacinian mechanoreceptors within range of the sternum contribute substantially to heartbeat sensations. We herein provide novel evidence to support the view that the somatosensory system is implicated in heartbeat detection.

This study clarifies whether previously found emotion‐related impairment of inhibitory control among individuals with antisocial traits is unique to negative emotion or is instead a broader effect of emotional arousal. This study offers insight into how cognition–emotion relationships function across facets of psychopathic traits. Results suggested that future theoretical and therapeutic work may benefit from focusing on emotion broadly, rather than negative emotion specifically, when studying or targeting inhibitory control in psychopathy.
