Would you like to find out more about the brain hemispheres and how they communicate to solve everyday cognitive tasks, including language processing? Are you interested in methods developed to investigate hemispheric specialization and interhemispheric communication? Come and join us at the meeting of the PSYCHOLinguistics Reading Group (Monday, November 25th, 2013, 6.30 p.m., 101A). The meeting will be devoted to Lateralization and interhemispheric cooperation.
When and why are two brain hemispheres better than one?
Lateralization vs. interhemispheric cooperation
presented by mgr Anna Klecha
Research on the human brain has shown that our cerebral hemispheres are specialized for different tasks – a phenomenon termed as lateralization of function, the degree of which is unique to humans. At the same time, however, it has become evident that only a small proportion of all the tasks that our minds encounter every day is executed exclusively by a single hemisphere. Instead, a substantial amount of what we think and do is subserved by ongoing interhemispheric cooperation. Through the use of both neuroimaging techniques and behavioral methods, researchers have shown that even the execution of tasks for which one of the hemispheres is dominant (e.g. linguistic processing that falls in the domain of the left brain) involves differential contribution from the other hemisphere. Moreover, it seems that the need for interhemispheric processing increases with task complexity, producing performance of its own kind that is neither a copy nor a sum of the two processing styles of each hemisphere alone.
