A fáradtság szorosan hozzátartozik az egészséges mindennapjainkhoz és a betegségeinkhez is. Ennek köszönhetően a fáradtság-jelenségekkel kapcsolatos vizsgálatok száma jelentős, de az összetevők nagy száma és az egyes jelenségek variabilitása mind a mai napig komoly nehézség elé állítja a fáradtság-kutatást. A jelen áttekintő tanulmány célja az, hogy átfogó képet adjon a leggyakoribb, illetve a legjobban dokumentált krónikus fáradtság-jelenségekről, például a post-stroke fáradtságról, a krónikus fáradtság szindrómáról és a depressziós fáradtságról. A felsorolt példákon keresztül láthatóvá válik a fáradtság sokdimenziós, a biológiai és pszichológiai mechanizmusok hálózatára épülő jellege. A tanulmány célja ugyanakkor az is, hogy bemutasson egy elméleti koncepciót, a főbb módszertani lehetőségeket, és a kutatási terület kulcskérdéseit.

In the vast majority of mammalian species, including humans, males provide less direct care to their offspring than females do. However, the theory of sexual selection suggests that the expression of paternal investment involves trade-offs between mating and parental effort associated with reproductive and survival related costs and benefits. In this view, different social and biological factors can distribute males' reproductive investment across parenting and mating behavior. As for social factors, the quality of resources held by males is one of the primary determinants of males' reproductive success. As for biological factors, the physical attractiveness is also highly correlated with males' mating success through enhanced access to females. In the present study the effect of males' socioeconomic status and facial attractiveness on direct childcare was tested on a sample of 81 Hungarian families. The first prediction was that males who possess lower status tend to engage more in direct childcare than males with higher status. This prediction was partially supported in our results. Second, we predicted that males rated more attractive provide less amount of direct paternal effort. The results seem to support this view in the case of men with higher socioeconomic status.

The mental rotation is a classical paradigm in cognitive psychology. Recent tests demonstrate that the linearity coefficient (r2) is an appropriate variable to show the cognitive appearance (cognitive strategy) of mental rotation. It is well documented that males perform better than females on object mental rotation. The present work is the first demonstration of a sex difference of cognitive strategy used during mental rotation. A linearity coefficient of females was higher than the coefficient of males. This result implies that females use a more active and powerful mental rotation strategy. This is very important from the viewpoint of some methodology. In the cognitive neuroscience there are various fMRI and MEG works which measure brain activity during mental rotation. However, beside the demonstration of mental rotation paradigm, it may be very important provide that subjects at whom occur actually the mental rotation during brain scanning.
