Abstract

VASQUEZ, Milena et al. Effects of assisted training with neurofeedback on EEG measures, executive function and mood in a healthy sample. Anal. Psicol. [online]. 2015, vol.31, n.1, pp.317-323. ISSN 1695-2294.  http://dx.doi.org/10.6018/analesps.31.1.167241.

The training in neurofeedback (NF) consists of teaching individuals to modify, adjust and enhance their brain activity pattern. The aim of our research was to evaluate the effect of training on cognitive processes, specifically executive function, and mood in a non-clinical sample. A sample of 30 female college students were assigned to three groups: RH: right hemisphere (n = 10), LH: left hemisphere (n = 10) and control (n = 10). The dominance pattern of beta and the inhibition of the theta pattern were trained in a single session. Measures of executive function (Iowa Gambling Test) and questionnaires of mood were taken pre and post training. We found that NF training produced significant positive changes in executive performance in the RH group. In the EEG a tendency to improve beta rhythm after the training emerged too. Additionally, significant correlations were found between executive performance and negative mood in relation to theta frequency band. We conclude that the protocol seems effective to enhance some aspects of executive function as well as to decrease theta power improves the negative mood.

Keywords : Neurofeedback; EEG; executive function; Iowa Gambling Test; mood; PANAS; POMS; theta rhythm; beta rhythm.
