U ovom istraživanju provjerili smo medijacijski efekt psiholoskih potreba na odnos životnog standarda i zadovoljstva životom. Na uzorku od 397 sudionika (55% žena) dobi između 22 i 47 godina (M = 31.23, SD = 8.71) prikupljeni su podaci o životnom standardu kucanstva, bazicnim psiholoskim potrebama i zadovoljstvu životom. Životni standard, psiholoske potrebe i zadovoljstvo životom su bili statisticki znacajno pozitivno povezani. Provedene regresijske analize su pokazale da su zadovoljenje potrebe za autonomijom (z = 4.06, p < 0.001), povezanosti (z = 2.53, p = 0.011) i kompetencijom (z = 4.46, p < 0.001) djelomicni medijatori odnosa životnog standarda i zadovoljstva životom, odnosno da bolji životni standard doprinosi vecem zadovoljstvu životom direktno i indirektno jer omogucuje zadovoljenje osnovnih psiholoskih potreba.

The sample consisted of 89 participants. All of them were female and right-handed. Odours quality discrimination was tested with twelve pairs of odours presented to each nostril of every participant. The half of participants had odours presented to their left nostril first ("left-right" group), while the other half had them presented to their right nostril first ("right-left" group). The data was analysed in order to compare the efficiency of odour discrimination of left and right nostril. The analyses were carried out on the whole sample, as well as on the "left-right" and "right-left" sub-groups separately. For the whole sample, the difference between average scores for left and right nostrils didn't reach statistical significance. However, the "left-right" group showed clear right nostril advantage for discrimination of odours. In the "right-left" group there was no significant difference between nostrils.

Rezultati su pokazali da ucitelji eksperimentalnih skola u vecoj mjeri primjenjuju strategije poucavanja iz programa Aktivna/efikasna skola: tijekom nastave vise se razgovara sjedeci u krugu, radi u grupama i ucenici cesce mogu izabrati problem koji ce proucavati. Ucitelji eksperimentalnih skola u odnosu na ucitelje kontrolnih skola ne razlikuju se u procjeni karakteristika skola, procjeni važnosti pojedinih poželjnih karakteristika i ocjeni odnosa ucenika prema skoli. No, u odnosu na ucitelje kontrolnih skola, ucitelji eksperimentalnih skola su znacajno zadovojniji skolom. Procjenjuju da su njihovi ucenici u manjoj mjeri ekstrinzicno motivirani za ucenje. nadalje, u visokoj mjeri ocjenjuju da program Aktivna / efikasna skola ima razlicite pozitivne karakteristike te da razvija poželjne osobine ucenika, kao i prijateljski odnos sudionika u nastavi. Rezultatima težinu daje i sukladnost s rezultatima dobivenim na uzorku roditelja i ucenika. Zakljucno, evaluacija na uzorku ucitelja upucuje da kurikulum Aktivna /efikasna skola pokazuje neke prednosti u odnosu na standardni kurikulum, kakav se uobicajeno provodi u osnovnim skolama.

Petrill and B.Wilkerson, 2000, Educ. Psychol. Rev., 12, 185-199). However, the majority of studies have examined that relationship in children typically aged between 5 and 13 years, with only one study using a sample aged on average 17 years. In our study, the relationship between scholastic achievement and intelligence was examined in a sample of twins (71 MZ, 78 DZ pairs) aged on average 17 years. Four different measures of intelligence were used, two that measured spatial abilities (visualization and spatial orientation) and two that measured verbal abilities (word fluency and vocabulary). Scholastic achievement was measured by three school grades obtained at the end of the first semester, Croatian, Mathematics and an average grade from all subjects. Univariate analyses indicated that the best fitting model for all measures includes additive genetic (A) and non-shared environmental (E) influences, with heritability estimates in the .60 to .80 range. Bivariate analyses between each of four intelligence measures as well as between composite intelligence score obtained as a factor score from four measures, and each of scholastic achievement measures were done using AE correlated factors model. Results showed that two verbal abilities and composite intelligence score shared from 49%-67% of genetic influences with each of scholastic achievement measures. For spatial abilities, shared genetic influences were found between spatial orientation and Mathematics grade (36%), and between visualization and Croatian (40%) and average grade (24%). Visualization also shared environmental influences with Mathematics (33%) and average grade (37%).

Some dispositional determinants of these behaviors include personality traits like Agreeableness and Honesty-Humility, as well as dispositional empathy. Moreover, there is certain evidence that even so called the Dark Triad traits (i.e. Machiavellianism, narcissism and psychopathy) can be related to prosocial and helping behaviors under certain circumstances. Therefore, the aim of this study was to explore relations between the basic and the dark personality traits, empathy and helping behavior. Study sample consisted of 337 students (280 female, 57 male, mean age 22.09, with SD = 3.72) in Croatia, that filled in on-line self-report measures of both basic and dark personality traits: HEXACO-60 (Ashton & Lee, 2009), Self-Report Psychopathy Scale-Short Form (SRP-SF, Paulhus, Newman & Hare, in press), the short form of Narcissistic Personality Inventory (NPI-16, Ames, Rose & Anderson, 2006), and Croatian Machiavellisanism Scale (MMS ; ), as well as the short form of Empathy Quotient (EQ, Baron-Cohen & Weelwright, 2004). After approximately one month, students were contacted and asked for a favor that, in average, took half an hour of their time. Surprisingly, doing a favor was not related neither to emotional nor cognitive empathy. Moreover, only psychopathy and narcissism among all the personality traits were related to doing a favor, indicating that those who have more pronounced traits of psychopathy and narcissism are less prone to helping behavior. In sum, these results emphasize the importance of the dark personality traits in the area of individual differences.

Prosocial behavior is intended to benefit others rather than oneself and is positively linked to personality traits such as Agreeableness and Honesty-Humility, and usually negatively to the Dark Triad traits (i.e., Machiavellianism, narcissism, and psychopathy). However, a significant proportion of the research in this area is conducted solely on self-report measures of prosocial behavior. Therefore, the aim of this study was to investigate the relationship between prosociality and the basic (i.e., HEXACO) and dark personality traits, comparing their contribution in predicting both self-reported prosociality and prosocial behavior. Results of the hierarchical regression analyses showed that the Dark Triad traits explain prosociality and prosocial behavior above and beyond the HEXACO traits, emphasizing the importance of the Dark Triad in the personality space.
