“…Last but not least, our results also show that some subjects' personality traits (moderation, openness and extroversion) affect the actual decrease/increase in size of Frequency at Maximum Power during active mental task solving. The influence of the personality dimension, extraversion/introversion, on the extent an topographical distribution of ERD in subjects engaged in cognitive information processing was also described by Fink (2005) and Fink et al (2005Fink et al ( , 2008. The paper by Jausovec (2000) studying the differences in cognitive processes related to creativity and intelligence by using EEG coherence and power measures should be mentioned here too.…”

ORIGINAL ARTICLEThe paper presents finding of an experiment the aim of which was to judge the impact of an instant cognitive activity (identical pictures searching) on behavior of ongoing EEG activity. Two types of mental task were used: The first -passive watching of a blank white oval and the second -active searching for identical pictures in a group of similar nine line-drawings of living individuals or inanimate objects filling out the white oval.Presented results showed that higher mental load pertinent to active searching for identical pictures in a group of similar pictures results in the prominent event-related desynchronization (ERD) -the mean Total Power value, a quantitative measure of ERD extent, in comparison with reference level (passive watching) was lower while solving the mental task.The results also showed that the actual mental task performance affects the ERD only at some scalp-recording sites. The mean EEG Total Power significantly decreases at parietal and frontal scalp-recording sites whereas the significant decrease of the Frequency at Maximum Power involves occipital scalp electrodes, too.Our results also demonstrated that some subject's personality traits (moderation, openness and extraversion) affect the actual decrease/increase in size of Frequency at Maximum Power during active mental task solving.Presented findings point at the high suitability of the ERD method to uncover differences in people's brain activation patterns when engaged in performing cognitively demanding tasks.

“…Interestingly, extraversion-related effects on cortical activity appear to be strongest exactly in those cortical regions that are actually needed to perform successfully on the task. This was, for instance, evident during working memory processing (see Fink et al, 2005), where extraverted (as compared to introverted) individuals showed a lower cortical activity in right-hemispheric frontal-parietal regions -regions that are known to be involved in attention and working memory. In a broader sense, the finding that individual differences in the personality dimension extraversion account for variability in brain responses to a variety of cognitive demands also supports the idea of personality (extraversion) and ability as interplaying rather than independent domains.…”

“…IAF contribution to extraversion also increased from 7.2% to 12.2% in males as well as increasing from 3.4% to 12.2% in females. Other studies that used either individually determined alpha bands (Tran et al, 2001) or the IAF method (Klimesch, 1999) as did Fink and Neubauer (2004) and Fink et al, 2005, have found strong associations between alpha wave activity and extraversion.…”

“…For reasons given by Klimesch (1999), individually defined alpha frequency band (IAF) was also used in this study. IAF was determined individually for each participant by using the dominant EEG frequency (indicated by the highest amplitude peak) and used as the anchor point (Fink et al, 2005;Klimesch, 1999). Once the IAF was determined, three different frequency windows with a bandwidth of 2 Hz were defined these are: lower1 alpha (IAF-4 Hz to IAF-2 Hz), lower2 alpha (IAF-2 Hz to IAF), and upper alpha band (IAF to IAF + 2 Hz).…”
