Opis: Student samples have become a widely used resource in the study of not only particular phenomena and problems within individual environments but also of their study within a cross-cultural context. A number of such studies, most often generalizing their results to the level of cultures, are illustrated in this article. In addition, the authors carry out a number of empirical tests of the generalizability of results attained on student samples in cross-cultural research. Based on the World Values Survey data, mean values of four sociologically and psychologically relevant measures are compared between national and student samples of twenty-three countries. Results suggest that the findings attained on student samples can be viewed cautiouslyas a good indicator of national sample rankings in cross-national comparisons.

, 2012, pregledni znanstveni članek
Opis: Namen prispevka je prikazati novo napravo, senzorsko kontaktno lečo Triggerfish, za stalno merjenje intraokularnega pritiska, dosedanje izkušnje in oceniti možnost njene uporabe. Prikazane so do sedaj objavljene raziskave na to temo. Naprava se dobro prenaša, je varna, preiskava se lahko ponovi. Do sedaj je še premalo podatkov, da bi jo lahko uporabljali že v vsakodnevni praksi pri zdravljenju glavkoma. Potrebne bodo še dodatne raziskave.

Opis: Synonyms for the word boldness include courage, fearlessness, heroism and bravery. The best examples of courage in sport are athletes who, despite difficult situations, conditions and strong competition, perform very risky elements, break records, etc. The "Fall back" measurement instrument has been used in the selection process for artistic gymnastics. Bearing in mind that this test requires a drop back down an inclined plane, it requires a degree of courage in the realization of this motor task. The aim of this research is to determine the validity of the "fall back" test and to answer the question: Is the "Fall back" test actually a measure of courage among beginners in the sport? In this study, the research sample consisted of 16 boys and 33 girls, third graders from the Jovan Cvijic elementary school in Kostolac, aged nine years (+/- 6 months). The sample of variables represented the results written using two measurement instruments: 1. Psychological survey -test of boldness and courage - PSBC (a test modeled after the - Erikson`s theory of Psyhosocial Development test - About.com Psyhology); 2. Situational motor measuring instrument - Fall back - MFIB. The resulting measurements were analyzed by the appropriate statistical methods, which are congruent with the set objective and task ofthe study. The validity of the "Fall back" situational-motor test is determined by calculating the coefficient of correlation (r) between said composite test and a psychological test of courage. The very high coefficients of correlation that resulted in all three cases (total sample r = .846, sample of boys r = .873, a sample of girls r = .845) indicate a high validity level for the test, "Fall back", that is, the subject of measurement in the test, largely corresponds with the subject of measurement in the PSBC psychological test. The height of the correlation coefficient also justifies the use of the "Fall back" test as a composite test. A high validity of the "Fall back" measurement instrument (MFIB), which is indicated by the high Pearson coefficients of correlation between the"Fall back" measurement instruments and the psychological test of courage and boldness, was established for all three samples of respondents.

Critical thinking in educationJanez Bregant
, 2014, izvirni znanstveni članek
Opis: The study argues for the claim that a correct argumentation, i.e. a non-fallacious or good reasoning, should be the essential part of the education process, which is not always the case. The bad argumentation makes human standards and interpersonal relationships worse, and leads to the growth of social conflicts and an instable society. If the legislature, executive and judiciary branches of power did not listen to good arguments, our lives would not be as good as they are since the state might pass bad, dangerous and unjust laws. A person trained in critical thinking starting in their youth would be able to tell a difference between good and bad arguments and recognize the fact that accepting the former and dropping the latter is the only way to avoid the above mentioned negative characteristics of a society. By teaching pupils how to employ the prescribed standards of a correct argumentation using everyday examples helps them to avoid adopting certain views on the ground of their popularity, affections produced in observers, their popularity etc., which are classic examples of logical fallacies. An early training in critical thinking could make obvious the fact that, a democracy consisting among other things also in a social, racial and gender equality, after all, does not mean that sometimes left arguments win and sometimes the right ones, and that there is no difference between them in the long run.
