‘All of the Most Interesting Research Today Happens at the Borders between Different Disciplines’

‘All of the Most Interesting Research Today Happens at the Borders between Different Disciplines’
The Russian Ministry of Education and Science has approved a new nomenclature of specializations in which academic degrees are conferred in Russia. The new list includes 21 new fields, including cognitive science. Maria Falikman, Head of the HSE School of Psychology, discusses the history of cognitive science, its formation at HSE, and its prospects for development.

‘In the Blink of an Eye’ Statistics: People Estimate Size of the Set of Objects Based on Distance to Them

‘In the Blink of an Eye’ Statistics: People Estimate Size of the Set of Objects Based on Distance to Them
HSE University researchers Yuri Markov and Natalia Tiurina discovered that when people visually estimate the size of objects, they are also able to consider their distance from the observer, even if there are many such objects. The observers rely not only on the objects’ retinal representation, but also on the surrounding context. The paper was published in the journal Acta Psychologica.

Experiment Shows How Our Visual System Avoids Overloading

Experiment Shows How Our Visual System Avoids Overloading
Russian researchers from HSE University have studied a hypothesis regarding the capability of the visual system to automatically categorize objects (i.e., without requiring attention span). The results of a simple and beautiful experiment confirmed this assumption. The paper was published in the journal Scientific Reports. The study was supported by a Russian Science Foundation grant.

Attention Priority Map Explains Unusual Visual Search Phenomena

Attention Priority Map Explains Unusual Visual Search Phenomena
Researchers from HSE University and Harvard have found that the grouping of multiple elements in a visual display does not affect the search speed for an element with a unique combination of features. The Guided Search theory predicted such results. The study is published in the Journal of Vision.

Attention and Atención: How Language Proficiency Correlates with Cognitive Skills

Attention and Atención: How Language Proficiency Correlates with Cognitive Skills
An international team of researchers carried out an experiment at HSE University demonstrating that knowledge of several languages can improve the performance of the human brain. In their study, they registered a correlation between participants’ cognitive control and their proficiency in a second language.

Microgravity Changes Brain Connectivity: What Happens to the Human Brain in Weightlessness

An international team of Russian and Belgian researchers has found out that space travel has a significant impact on the brain: they discovered that cosmonauts demonstrate changes in  brain connectivity related to perception and movement. Some areas, such as regions in the insular and parietal cortices, work more synchronously with other brain areas after the space flight. On the other hand,  connectivity of some other regions, such as the cerebellum and vestibular nuclei,  decreases. The results of the study were published in Frontiers in Physiology.

Working Memory Is Structured Hierarchically: The Colours and Orientations of Objects Are Processed Independently

Researchers in cognitive psychology at HSE University have experimentally demonstrated that the colours and orientations of objects are stored and processed independently in working memory. However, it is easier for a person to remember these features when they belong to a single object: for example, it is easier for a person to remember and understand one graph on which both parameters are indicated (with a colour and a line shape, for example), than two different graphs in which the two parameters are shown separately. The results of the experiment were published in Acta Psychologica journal.
