The cognitive aspects like perception, problem-solving, thinking, task performance, etc., are immensely influenced by emotions making it necessary to study emotions. The best state of emotion is the positive unexcited state, also known as the HighValence LowArousal (HVLA) state of the emotion. The psychologists endeavour to bring the subjects from a negatively excited state of emotion (Low Valence High Arousal state) to a positive unexcited state of emotion (High Valence Low Arousal state). In the first part of this study, a four-class subject independent emotion classifier was developed with an SVM polynomial classifier using average Event Related Potential (ERP) and differential average ERP attributes. The visually evoked Electroencephalogram (EEG) signals were acquired from 24 subjects. The four-class classification accuracy was 83% using average ERP attributes and 77% using differential average ERP attributes. In the second part of the study, the meditative intervention was applied to 20 subjects who declared themselves negatively excited (in Low Valence High Arousal state of emotion). The EEG signals were acquired before and after the meditative intervention. The four-class subject independent emotion classifier developed in Study 1 correctly classified these 20 subjects to be in a negatively excited state of emotion. After the intervention, 16 subjects self-assessed themselves to be in a positive unexcited (HVLA) state of emotion (which shows the intervention accuracy of 80%). Testing a four-class subject independent emotion classifier on the EEG data acquired after the meditative intervention validated 13 of 16 subjects in a positive unexcited state, yielding an accuracy of 81.3%.

Traces of the idea of verbal valency structure in nineteenth-century grammars – This paper aims to show how K.F. Beckers’s notion of “subjektive” and “objektive Verben” (i.e. those always used with an “ergänzende Objekt”, a ‘completive object’) is a rough forerunner to the modern idea of dependency grammar. In Italy, this theoretical core was assumed by Raffaello Lambruschini in 1840 (and, after him, by the basic school grammar La grammatica del mio Felicino written by Ulisse Poggi, 1865, 18722), but with a huge trivialisation: subjective verbs were identified with intransitive verbs and objective verbs with transitive ones.

The subject of the presented article is Bulgarian, Polish and Russian emotive verbs, treated in perspective of syntactic valence. The author examines the grammatical forms of propositional argument in the sentences with emotive verbs that represent pre- dicate-argument structure P (x, q). All forms are divided into several types: observance, compression and splitting. The author shows that in this area we have to deal with analog reflection of propositional structure, or more or less compression of proposition argument, or its dismemberment and doubling syntactic position. The author takes into account the regularity of the implementation of each grammatical form, quoting the relevant quantitative data.
