The Influence of Alpha-Training on Auditory Evoked Potentials Depending on Individual Differences in Temperament

2012. Vol. 9. No. 3. P. 66–77 [issue contents]

An empirical study was conducted, aimed to find out the influence of alpha-training on auditory evoked potentials in a continuous attentional task setting with a binary answer choice and the dependency of the said influence on individual differences in temperament. All subjects were divided into experimental and control groups. Both groups had 2 identical experiments with the interval of 1 – 1.5 months. In the period between the experiments subjects of experimental group passed a training on biological feedback, aimed to train voluntary increase in alpha-rhythm in the upper part of individual range. In the second experiment in the experimental group there were found changes of the characteristics of the P2 and the N1-P2 complex, and the specific character of the change depended on three temperamental dimensions: neuroticism (according to EPI and NEO-FFI), mobility of nervous processes (according to PTS), and cooperation (according to NEO-FFI). The latency of P2 increased in subjects with high neuroticism and decreased in subjects with low neuroticism. The amplitude of P2 increased in subjects with high cooperation and high mobility of nervous processes. Also in subjects with high mobility of nervous processes the amplitude of the complex N1-P2 increased. Such changes didn’t happen in the control group. The suggestion is made that alpha-training influences patterns of brain activity, reflected in the given parameters of temperament. This leads to the transformation of early stages of brain processing of auditory stimuli during the task-solving and, accordingly, to changes in corresponding components of evoked potentials.
