- Genetically informative studies of cognitive abilities and other individual characteristics related to mathematical performance. A twin study is under way, collecting a wide range of measures from the twin pairs. Participants of the study perform behavioral tests and questionnaires, and then take part in EEG experiment. We also collect their saliva and anthropological measures. There is also a test-retest singleton (non-twin) group of the participants who take part in the study twice so that we can measure the stability of the tests.
- Simulation study of the bias introduced by confounding variables in twin research. Adjustment of the phenotypic variables for the effects of sex and age is widely accepted practice in twin research (McGue & Bouchard, 1984). Such variables may increase phenotypic similarity of twins introducing bias to the estimates of genetic and environmental effects. The aim of this study is to estimate the bias under various conditions (sample size, genetic and environmental effects, effect of confounding variable).
- Machine learning methods in analysis of brain activity data. There is a new field of Machine Learning, Deep Learning, which can take advantage of the graphical nature of EEG derived data and which has shown to outperform many methods for a wide range of applications (REF). ML methods and Artificial Intelligence methods including Deep Learning will allow researchers world-wide to make better use of current and future EEG derived data. We have samples big enough and computational capacities (cluster computer resources) to address this problem. The project involves working with EEG analyses experts to refine existing and develop new methods of multi-channel data analyses.
- Cross-cultural studies of executive functions. The project aims to collect executive functions data in Russia, UK, Kyrgisia, China and other countries to understand the nature of cross-cultural differences in variability and/or average performance in these abilities.
- Transcranial electric stimulation (TES) studies with control twin method. Electric Brain Stimulation is an invaluable tool in research into brain function. Applying this method in combination with using MZ twins as participants in experimental and placebo-groups provides a powerful test of potential effects. For such test we developed a TES protocol promising for improvement of learning skills.
- Executive functions and brain activity in children with local brain lesions. Together with clinicians we are investigating the psychological and psychophysiological states of children who came through brain surgery. We use neuropsychological test batteries, eye-tracking and EEG to assess the effectiveness of recovery and training procedures these children undergo.

1. Congruency and complementarity effects in processing of emotional information.
Research questions -
What are the relationships between specific emotional states of an individual and a facilitation or an inhibition
(1) of the processing of various types of emotional stimuli
(2) or of the recognition of particular emotions?
2. Effects of moods on the scope of cognition.
Research questions -
What are the mood dimensions that influence the scope of cognition? Are they valence, arousal, motivational intensity or their combinations?

1. Ensemble perception in vision
Our capacity to process information deeply (pay attention to objects, maintain them in working memory, recognize, and record to long-term memory) is severely limited to a small handful of objects at one time - probably no more than 2-4 items. However, our visual experience is much broader than just a few objects every moment. Basically, we believe that we are aware of everything our eyes are currently looking at. How can our visual system deals with this? One promising theory says that this ability is supported by efficient computation of summary statistics across big collections of objects and their features. The representation of multiple objects in the form of statistical summaries is often referred to as ensemble perception. If I show you, say, 20 circles with various sizes for just 1/5 sec and then show you a single circle and ask “Did you see a circle of exactly that size a moment ago?”, you will likely have no idea - because of your limited capacities. But if I ask you “Is this circle larger or smaller than the mean size of all circles?”, your answer will be surprisingly accurate. Our lab does a lot of work on ensemble perception trying to understand how the visual system is capable of doing so efficient computations so quickly.
2. Visual working memory and long-term memory
We are extremely interested in how people store and retrieve information about objects they have seen. Visual working-memory is a limited-capacity and relatively short-term storage actively maintaining information about a few objects that are necessary for an ongoing task. Long-term-memory is a much bigger and long-lasting storage for objects that we have seen before and left working memory (if not forgotten). In our lab, we study many intriguing questions about these memory systems. What is the format of stored representations - are objects stored as whole units or their features are stored separately (e.g., is shape of an object is stored separately from its color)? How do objects remembered together affect and probably distort each other’s representation in memory? Are real-world objects (things that we see and use every day) stored differently than simple meaningless lab objects (like simple geometric shapes of random colors)?3. Visual search and selective attention
Within this topic, we investigate how people exploit their limited-capacity attentional mechanisms to find things they want to find (targets) among the irrelevant stuff (distractors). How do the physical properties of the scene affect the difficulty of search? How does the knowledge of target features “guide” attention towards a potential target and allows to bypass a lot of things without even looking at them? What if you look for several different things at one time? How does your previous experience in a search task change your ability to find things quicker and accurately (the question relevant for some occupations such as radiology diagnostics or security check in the airport)?

1. Rapid brain system for semantic analysis of written words.
How quickly can we extract semantic information during reading? The study of brain activity provides the answer that we can’t get with any behavioral technique. Indeed, while it takes quite a lot for you to read this text (about 10 seconds on average), your brain needs less than 100 ms to distinguish whether the word is abstract or concrete (Sysoeva et al., 2007). How can we use this intriguing finding to improve the reading skills? In your thesis this topic will be expanding into subconscious analysis of written words. The goal is to describe the neurophysiological mechanisms of rapid semantic analysis using EEG/MEG technique.
2. Time perception: gene-brain-behavior.
Our subjective perception of time can be studied by objective methods of psychophysics and EEG/MEG. Moreover, we can track individual differences in this ability into genetic polymorphisms (Sysoeva et al., 2010). The topic of your thesis might be related to neurophysiological mechanisms of time perception and its influence by external factors (Sysoeva et al., 2013; Portnova et al.,2010). How other psychological traits (e.g. impulsivity) correlates with individual differences in time perception being related to the same neurogenetic characteristics. Alternation in the subjective time flow in different neuropsychiatric conditions might be also considered. Why the main part of the work will be based on human studies, we might be able to test some of our hypothesis in the experiments with rodents.
3. Psychophysiological profile of autism spectrum disorders and associated genetic syndromes
By recording the EEG and extracting its activity related to particular sensory and cognitive abilities we aim to construct a non-invasive objective psychophysiological profile of different subtypes of autism spectrum disorders. The thesis topic might be linked to different aspects within the above identified framework, including application of advanced EEG analysis technique (e.g. machine learning) to the unique EEG datasets.
