The average age of diagnosis is between three and eight years of age; however, in retrospect many parents will say that their child displayed signs of excessive shyness and inhibition since infancy.
This is because it contains an amino acid called L-theanine, which was shown in a 2006 Nagoya University Department of Psychology study to reduce physiological stress responses "via the inhibition of cortical neuron excitation."
In the statics two magnitudes have to be determined: (I) the amount of the suppression or inhibition (Hemmungssumme), and (2) the ratio in which this is shared among the opposing presentations.
More important is the law according to which a presentation freed from inhibition and rising anew into consciousness tends to raise the other presentations with which it is combined.
When its remainder after inhibition=O, a presentation is said to be on the threshold of consciousness, for on a small diminution of the inhibition the "effort" will become actual presentation in the same proportion.
