“…The lack of an effect of alcohol on movement time confirms Hunt ley's [65] notion that response execution is less likely to be affected by alcohol. On the other hand, the finding of faster movement times in extraverts than in introverts supports the hypothesis that motor mechanisms play a fundamental role in extraversión [58,[66][67][68]. However, there is no indication that extraverts are more susceptible to the sedative effects of alcohol with regard to these motor mechanisms.…”

Within the framework of Eysenck’s drug postulate alcohol is frequently used as an example for a depressant drug that should shift a person’s position on the extraversion-introversion axis in the direction of lower arousability. However, only little experimental evidence for differential effects of alcohol on extraverts and introverts appears to exist. Therefore, a placebo-controlled study was designed to investigate the effects of 0.65 g/kg alcohol on temporal discrimination, time estimation, reaction time, movement time, critical flicker fusion frequency (CFF), as well as feelings of activity, alertness, drowsiness, joyfulness, and relaxation in introverts and extraverts. While a main effect of alcohol could be shown for temporal discrimination (p < 0.05), reaction time (p < 0.05), CFF (p = 0.01), and feelings of alertness (p < 0.001) and joyfulness (p < 0.01), significant interactive effects of alcohol and extraversion were only found for time estimation (p < 0.001) and feelings of relaxation (p < 0.01). Extraversion-related differences in movement time (p = 0.05) proved to be insensitive to alcohol. Results are discussed with regard to the pharmacological profile of alcohol and the validity of the drug postulate.

The paper presents findings of an experiment the participants of which were native Czech speakers (L1 ) possessed of perfect knowledge of English (L2). We assumed that the subjects could process differently each of the three types of English and Czech sentences; the first type represented correct sentences, the other two violated sentences. Violated sentences differed in the precise relationship between the verbs, their preceding noun phrases, and their preceding context. ERPs to critical verbs, the accuracy rate for both English and Czech sentences processing and decision time for each were evaluated. Participants' personality traits were assessed too. It has been shown that our subjects, who learned English after the age of 15, displayed significant differences in all measured parameters. It was especially the longer latency N400, the lower accuracy rate of English sentence processing, the longer decision time, and the same dynamics of all measured ERPs parameters. Possible causes of these differences are discussed.

Abstract-Common guidelines followed in the animation community include the idea that cartoon characters should be exaggerated to better convey emotion and intent, whereas more realistic characters should have "matching" realistic motion. We investigated the effects of rendering style and amount of facial motion on perceptions of character likeability, intelligence, and extraversion. We used cartoon and more realistic-looking characters that were animated with tracked actor motion. The motion was exaggerated and damped in 10% increments up to a 40% difference from the original motion. We discovered that motion changes ±20% from original motion affected perceptions of likeability and intelligence differently in the realistic-looking and cartoon characters. The realistic-looking characters benefited from increased motion whereas the cartoon characters benefitted from damped motion. Furthermore, the amount of facial motion and perceptions of extraversion were significantly correlated.
