Doctoral student from the School of Natural Sciences and Health Valdar Tammik defended his doctoral thesis 'Relationships between dominant structure of word meanings and visual figure discrimination'.

In a new research study published in Current Biology, scientists have now discovered the neuronal changes that occur during learning to improve discrimination of closely related visual images.

During both development and adulthood, learning can alter visual perception. For example, improved visual discrimination of similar patterns is a learned skill critical for reading.
