Abstract The aim of this study was to investigate the relationship between three temperament dimensions: strength of excitation, strength of inhibition and mobility measured by Pavlov’s Temperament Survey (PTS), and amplitudes and latencies of evoked brain potentials (N1, P2, N2, P3 & SW) measured by a visual oddball paradigm in two blocks. The participants were female psychology students (N=54) with mean age of 20. Significant positive correlations were determined between amplitudes of N1-P2-N2-P3 components and strength of excitation and mobility in the first and second block, mostly on parietal electrodes, as well as significant negative correlations of amplitudes of N1-P2-N2-P3 components and strength of inhibition. Considering measurement limitations important future study directions have been given.

Recent streams of research support the Whorfian hypothesis according to which language affects one's perception of the world. However, studies of object categorization in different languages have heavily relied on behavioral measures that are fuzzy and inconsistent. Here, we provide the first electrophysiological evidence for unconscious effects of language terminology on object perception. Whereas English has two words for cup and mug, Spanish labels those two objects with the word “taza.” We tested native speakers of Spanish and English in an object detection task using a visual oddball paradigm, while measuring event-related brain potentials. The early deviant-related negativity elicited by deviant stimuli was greater in English than in Spanish participants. This effect, which relates to the existence of two labels in English versus one in Spanish, substantiates the neurophysiological evidence that language-specific terminology affects object categorization.

The Relationship

In this section, research aim, problems and hypothesis with the methods and determined research results will be presented. This correlational design research that has been run on a sample of N=54 students in Croatia will be described. The main findings regarding the relationship between personality traits extraversion and evoked brain potentials will be presented. Personality traits that were explored are: extraversion, neuroticism, psychoticism, social desirability, addiction, criminality, empathy, impulsivity, adventurousness, strength of excitation, strength of inhibition, mobility, and depression. Latencies and amplitudes in two trials were investigated for the following evoked brain potentials: N1, P2, N2, P3, and Slow wave activity. Visual oddball paradigm was used for evoking brain activity measured on two occipital and two parietal electrodes. Results on controlled variables, such as: age, sight characteristics, coffee drinking, smoking, taking medications, alcohol and drug consumption, and body exercise, are introduced as well. The correlation analyses revealed a significant relationship between personality traits and evoked brain potentials, especially trait adventurousness and social desirability, due to a too simple and monotonous visual task that was use. The determined findings from the PCA factor analysis with Varimax rotation determined 15 factors that explained 79,611% of the total variance. Series of Hierarchical regression analyses for each personality trait individually revealed, as it was expected, certain visual evoked potentials as significant predictors.

AbstractThe default mode network (DMN), the salience network (SN), and the central executive network (CEN) could be considered as the core resting-state brain networks (RSN) due to their involvement in a wide range of cognitive tasks. Despite the large body of knowledge relating to their regional spontaneous activity (RSA) and functional connectivity (FC) of these networks, less is known about the influence of task-associated activity on these parameters and on the interaction between these three networks. We have investigated the effects of the visual-oddball paradigm on three fMRI measures (amplitude of low-frequency fluctuations for RSA, regional homogeneity for local FC, and degree centrality for global FC) in these three core RSN networks. A rest-task-rest paradigm was used and the RSNs were identified using independent component analysis (ICA) on the resting-state data. We found that the task-related brain activity induced different patterns of significant changes within the three RS networks. Most changes were strongly associated with the task performance. Furthermore, the task-activity significantly increased the inter-network correlations between the SN and CEN as well as between the DMN and CEN, but not between the DMN and SN. A significant dynamical change in RSA, alongside local and global FC within the three core resting-state networks following a simple cognitive activity may be an expression of the distinct involvement of these networks in the performance of the task and their various outcomes.

The Relationship

In this section an overview on evoked brain potentials will be introduced, same as the bases of electrophysiology of the brain. The main research findings on evoked potentials and other psychological variables such as cognition, emotion, motivation and personality will be presented. The emphasis will be given to the relationship between evoked brain potentials and personality operationalized by previously presented two personality theories: Eysenck's and Strelau's theory. Even though it is possible to expect, based on arousal theory, that introverts who had higher sensory reactivity on physical stimuli of moderate intensity and higher levels of cortical arousal than extraverts, would also show higher P300-amplitudes in both modalities, audio and visual, due to other significant variables (i.e. task type, other psychological and physiological characteristics of subjects, etc.) some other results could be expected. Therefore, all complexity about the relationship between evoked brain potentials and human personality and relevant research methodology will be presented here.
