Seeing an angry individual in close physical proximity can not only result in a larger retinal representation of that individual and an enhanced resolution of emotional cues, but may also increase motivation for rapid visual processing and action preparation. The present study investigated the effects of stimulus size and emotional expression on the perception of happy, angry, non-expressive, and scrambled faces. We analyzed event-related potentials (ERPs) and behavioral responses of N = 40 participants who performed a naturalness classification task on real and artificially created facial expressions.

Some studies, utilizing the menstrual cycle as a hormonal model, attempted to demonstrate that hormonal fluctuations could predict variations in emotion recognition, but with merely inconsistent findings. Remarkably, the interplay between hormone fluctuations and other person-related factors that could potentially influence emotion recognition remains understudied.

A particular focus here lies on what became known as bland-or sluggish-schizophrenia, a particular term coined in the USSR, which became known for its frequent use in internationally contested diagnoses of human rights activists. The argument follows the diagnosis of sluggish schizophrenia from its inception in a highly productive and equally international psychiatric community of the early 20th century pioneered by prominent Soviet scholar Andrey Snezhnevsky and through its epistemic detachment and content-related transformation in the highly isolated Soviet psychiatric community since the interwar period.

Similar to the scrambling of images, the scrambling of auditory signals is aimed at creating stimulus instances that are unrecognizable but have comparable low-level features. In the present study, we generated scrambled stimuli of short vocalizations taken from the Montreal Affective Voices database (Belin et al.
