Cognitive and affective psychology

How a person perceives and processes the world around them - this has long been one of the central themes in our institute's research. Keep reading about the questions our researchers are trying to answer in this field.



Visual perception 

The main mechanisms of vision: recognition of objects, differentiation of visual features, visual search, crowding, attention. Evaluation of the statistical properties of the image (number of objects, average size, etc.). Vision models (psychophysical, computational and neural networks).

Auditory and language perception 

Projects:  

  • We try to identify automatic language-specific indexes of the processing in the brain that were applicable to the assessment of acquisition of the mother and foreign language  
  • Effect of linguistic and musical experience on the processing of language in the brain 
  • Neurocognitive mechanisms of receptive language deficit in Estonian preschool age children 
  • Language and auditory brain: studies on central sound representation in auditory cortex (BerTa-LAB)

Attention and cognitive control 

A lot of information possibly influencing behaviour is processed pre-attentively, but can be accessed by modern cognitive neuroscience, for example by registering the brain’s automatic responses to deviance (mismatch negativity, MMN). MMN deteriorates in many clinical conditions but it is unknown whether the decrease is general or construct-specific. We ask how the automatic information processing is related to trait and state variables, and whether the relationship is general or specific.

Autobiographical memory and knowledge accumulation

Autobiographical memory development and outcomes are related to personal, socio-cultural, and situational factors. We focus on all three aspects to provide a better understanding of autobiographical memory, about its development and place in everyday knowledge accumulation. In particular, we try to understand: (1) how are values related to first memories throughout the timespan (socio-cultural level; (2) how are other cognitive abilities and genes related to autobiographical memory in middle childhood (personal level); (3) how can the context (e.g., the informal learning environment) best support memory for the experience and knowledge accumulation (situational level).

Affective representations 

Two types of interrelated representational representations are central to behaviour: goals and appraisals. We are interested in how these representations arise and how they affect emotions, motivation, and cognition. We approach these questions assuming that the mind is a cybernetic predictive system. In our empirical work we use behavioural web experiments, psychophysiological laboratory experiments as well as computational modelling of their results.

Affective influence on cognition 

Thoughts and feelings are not separate phenomena but integrated parts of the mind. We use behavioural and psychophysiological experiments to understand how affective states such as emotions and mood shape various aspects of cognition from attention to decisions. Among other questions, we are interested in which components of affective states cause cognitive changes and how different cognitive changes driven by affect relate to each other.

Consciousness 

According to the prevailing scientific view, consciousness is a function or a corollary effect of the living brain. However, up to the present day it is unclear precisely how the brain brings about our conscious experience. The main methodological approach in respective research capitalizes on combining experimental paradigms of psychology (including specific experimental phenomena of consciousness) with methods and knowledge from brain research. We continue our experimental and theoretical studies in this domain.
