We can create memories and learn from two-dimensional images

September 27th, 2011

Viewing two-dimensional images of the environment, as they occur in computer games, leads to sustained changes in the strength of nerve cell connections in the brain. In Cerebral Cortex, Prof. Dr. Denise Manahan-Vaughan and Anne Kemp of the RUB Department for Neurophysiology report about these findings. When the researchers presented rats with new spatial environments on a computer screen, they observed long-lasting changes in the communication between nerve cells in a brain structure which is important for long-term memory (hippocampus). Thus, the researchers showed for the first time that active exploration of the environment is not necessary to obtain this effect.

“These results help to understand to what extent digital learning in the brain competes with learning in the “, says Manahan-Vaughan. “This is interesting for developing strategies for use of digital media in school. Such strategies can prove a useful antidote to the apathy in children towards the traditional teaching methods.”

“School teachers, particularly at the junior school level have become increasingly concerned at their observations that each generation of school children exhibits shorter attention spans and poorer retention abilities than the previous generation”, states Manahan-Vaughan. “One explanation for this is the ever increasing use of the digital media by school children. Our results indeed show that mammals can learn equally well when they passively view information on a computer screen compared to actively exploring the environment for this information. Television or computer games after school may compete with the information learned in school.”

In other words, we can learn from computers.
