Tachistoscopic experiments – the past and the future of tachistopical experiments
Vobořil, Dalibor ; Květon, Petr ; Jelínek, Martin
Tachistoscope has been one of the crucial instruments of the experimental psychology since its early times. This instrument is still in use in recent times, e.g. in the area of subliminal perception studies. The tachistoscopes have been evolving since the first experiments; nowadays, researchers do not use a single-purpose instrument to present the stimuli; they employ a personal computer with a monitor screen as a display unit. Two common technologies currently used at monitor screens - CRT and LCD - have different technical parameters (e.g. decay/refresh characteristics). The aim of our study is to explore whether the different parameters of the tachistoscopic instruments influence the resulting data, i.e. whether they cause an unsystematic measurement error. The results of the comparison of four types of tachistoscopic presentation will be presented in the paper. Two original mechanical tachistoscopes (Wundt-style tachistoscope, a tachistoscope with a photographic shutter) and two modern displays (CRT and LCD screens) are included in our experiment.

Sobotková, Veronika ; Blatný, Marek ; Hrdlička, M. ; Jelínek, Martin ; Květon, Petr ; Vobořil, Dalibor ; Urbánek, Tomáš
The study deals with relation between antisocial behavior in adolescence and school environment. The Social and Health Assessment (SAHA), a school survey, was administered to a nationwide sample of 4,980 adolescents in three age cohorts (12, 14, and 16 years) in Prague and 12 regional capitals of the Czech Republic. In present study we focus on cohorts of 12 and 14 years old adolescents (N = 3023). K-means cluster analysis on the items of Antisocial Behavior Scale was used to identify the main clusters of antisocial behavior. Four major clusters of children were identified. Subsequently, adolescents from different clusters were compared on the levels of their attachment to school, school climate, perceived support from teachers and general motivation to study. As we expected, adolescents from the cluster with high rate of antisocial behaviors perceive the school environment as the most negative.

Smoking of cigarettes in adolescence and its relations
Květon, Petr ; Jelínek, Martin ; Vobořil, Dalibor ; Balaštíková, Veronika
In the presented study, 3 types of respondents were identified according to the frequency of smoking cigarettes: smokers, non smokers, and occasional smokers. It was found that they differ in the type of attended school and also in school motivation, but not in proportion of males and females. When considering parental styles, smokers were characterized by low consistency, warmness, and involvement. Parental control was not found to be important. Smoking of cigarettes is related to alcohol, marijuana, and other substances use. Interestingly enough, most of the cigarettes smokers (81%) were found to be also repetitive users of marijuana

České univezitní sbírky historických experimentálních instrumentů
Vobořil, Dalibor ; Květon, Petr ; Jelínek, Martin
Historians of psychology often ignored historical instruments of experimental psychology. But the significance of historical experimental instruments is indisputable. On their example of importing essential knowledge from other disciplines and using them for psychological purposes we can prove the progressivity of psychology. In this paper we tried to map the “terra incognita” of history of psychology – we tried to describe and examine most of the preserved collections of historical psychological instruments in the Czech Republic.

Blížkovská, J. ; Klimusová, H. ; Jelínek, Martin ; Blatný, Marek
The study is a part of the research project: The determinants of life satisfaction in the contemporary adolescent youth: personality, values and social perspectives (supported by GA ČR). The present study focuses on the relations among value orientations and life satisfaction. Value orientations are derived on the basis of empirical typology, and personality determinants are taken into account as well. The research sample consists of the adolescents (n=841) attending second and third classes of various types of secondary schools in South Moravia.
