There are several ways in which cognitive and neurophysiological parameters have been consistently used to explain the variability in cognitive ability between people. However, little has been done to explore how the sources of variability in cognition are influenced by individual differences in personality traits. Dispositional mindfulness and anxiety are two reciprocally linked traits that have been independently attributed to a range of cognitive functions. The current study investigated the relationship between these two traits and measures of the attentional network, cognitive inhibition, and visual working memory capacity. 392 prospective participants were screened to create two experimental groups each of 30 healthy young adults, divided into high mindfulness-low anxiety (HMLA) and low mindfulness-high anxiety (LMHA). They performed an attentional network test, a color Stroop task, and a change detection test of visual working memory capacity, in addition to recording of resting EEG. Results showed that HMLA individuals were more accurate than the LMHA individuals on Stroop and change detection tasks. Additionally, the former group was better in detecting change and had a higher working memory capacity than the latter group. Although there were no group differences for the resting state eyes closed condition, for the eyes open condition, the LMHA group showed higher activation of beta frequencies in frontal and central areas and higher activation of gamma frequencies in central areas of the left hemisphere. This activation of higher frequencies may indicate that LMHA individuals may show greater emotional and physiological arousal than HMLA people (Oathes et al., 2008).
