Researchers of the HSE University and the Southern Federal University (SFedU) have tested a new method for studying the perception of facial emotional expressions. They suggest that asking subjects to recognise emotional expressions from dynamic video clips rather than static photographs can improve the accuracy of findings, eg in psychiatric and neurological studies. The paper is published in Applied Sciences.

Researchers from the HSE Laboratory for the Neurobiological Foundations of Cognitive Development, Alexey Kotov, Ivan Aslanov and Yulia Sudorgina, have experimentally proved that categorical labels, including nonexistent medical terms, significantly affect people's judgments, activating semantic knowledge in memory. The study has been published in the Frontiers in Psychology journal.

Neurobiologists from HSE University and the RAS Institute of Higher Nervous Activity and Neurophysiology proved that the human brain unconsciously distinguishes between even very similar sound signals during passive listening. The study was published in Neuropsychologia.

While Roscosmos is discussing future manned flights to Mars, NASA plans to open the International Space Station for commercial tourism, and SpaceX is testing its Starship Mars prototype, scientists are seriously concerned about the impact of prolonged stay in space on the human body. While the effects of weightlessness on bones, muscles and the vestibular system are well known, how the human brain copes with microgravity has yet to be fully examined. IQ.HSE has compiled the latest research on this topic.

According to HSE researchers, men with a high 2D:4D ratio (i.e. those whose index finger is longer than their ring finger) tend to be better educated. These findings are presented in the paper «2D: 4D and lifetime educational outcomes: Evidence from the Russian RLMS survey» in Personality and Individual Differences.

Several studies have indicated that schizophrenic patients are likely to show high levels of nicotine dependence. Scientists from Higher School of Economics (HSE), Institut Pasteur, the CNRS, Inserm and the ENS employed a mouse model to elucidate how nicotine influences cells in the prefrontal cortex. They visualized how nicotine has a direct impact on the restoration of normal activity in nerve cells (neurons) involved in psychiatric disorders such as schizophrenia. These findings were published in a paper that appeared in the journal Nature Medicine.
