Principle

This experiment provides an insight into how the processes of the brain become autonomous. At higher levels of concentration, the human body shows not only tangible or visible reactions, but also invisible reactions, e.g. an increase in skin conductance.

Benefits


No danger due to electrical energy thanks to wireless operation

Data acquisition with tablets possible

Simple operation of the app, therefore appropriate for all education levels

During short tests (e.g. reading of a text) the reaction can be observed immediately


Tasks


Proof of a higher level of concentration when the test person reads a black/white series of words compared to a series of coloured words.

Proof of a higher level of concentration when the test person must identify colours based on a series of squares compared to coloured words.
