Importance of the stabilization of the electrodermal activity in relation with the manipulation of some respiratory parameters

The main aim of this study is to know at what point, is the skin conductanc e level of the subjects stabilised and in what conditions this takes place. We are purporting to do an experimental design in which strange variables may alter the results we want to observe. 20 subjects participated in the s tudy. All of them were subject to a series of respiratory frequencies (6, 1 0, 14, 18 and 22 cycles per minute). for three minutes. Simultaneously meas urement of SCL were taken every 2 seconds in order to obtain the average va lues minute by minute. The results of the experiment showed. on the one han d, that when respiratory frequencies were induced with a difference of 8 cy cles between them, the SCL was destabilised from the first minute and conti nued to be destabilised until the third. on the other hand, it showed that when the respiratory frequencies were induced with a difference or 4 cycles between them, an initial destabilisation was observed which remained only for the first minute of measurement and was stabilised from the second minu te onwards.
