Diurnal variations in the activation level and some personality characteristics

Ispitivao se odnos između ekstraverzije-introverzije te navika svakodnevnog života (jutarnjost-večernjost) s jedne strane i dnevnih varijacija u stupnju aktivacije tokom dana s druge strane. Kao pokazatelji stupnja aktivacije upotrebljeni su frekvencija pulsa i oralna temperatura. Utvrđeno je da između dimenzije ekstraverzija-introverzija i svakodnevnih navika rada tokom dana (jutarnjost-večernjost) ne postoji značajna povezanost, ali da je svaka od tih dimenzija ponašanja pojedinačno povezana sa stupnjem aktivacije tokom dana. Najveće razlike u stupnju aktivacije tokom dana postižu se kad se kombinira sukladno djelovanje ispitivanih dimenzija ponašanja, jer su najveće razlike postignute između introvertiranih ispitanika koji su ujedno i jutarnji »radnici«, te ekstravertiranih ispitanika koji su ujedno i večernji »radnici«.The relationship between extroversion-introversion and every-day life habits (morningness-eveningness) on one hand, and diurnal variations in the activation level on the other hand were studied. Heart rate and oral temperature served as activation indicators. There was no significant correlation between the dimensions of extroversion-introversion and every-day working habits but each of these dimensions of behaviour was associated with the activation level during the day. The greatest differences in the activation level during the day were observed if congruent effects of the studied dimensions of behaviour were combined. This was the case with the subjects who were both introvert and »morning workers« and those who were both extrovert and »evening workers«
