The present study explores the relationship between Cloninger scales and Strelau's Regulative Theory of Temperament (RTT ) traits. Cloninger's psychobiological model identifies four dimensions of temperament (Novelty seeking, Harm Avoidance, Reward Dependence and Persistence) and three dimensions of character (Self-Directedness, Cooperativeness and Self-Transcendence). RTT proposes the traits of Briskness, Perseveration, Sensory Sensitivity, Emotional Reactivity, Endurance and Activity as the basic dimensions underlying individual differences. The relationships between the dimensions of Cloninger's Temperament and Character and Strelau's Regulative Theory of Temperament are investigated in a sample of 282 participants. Data analysis demonstrated some significant correlations between the two models. The strongest associations were found between the dimension of Harm Avoidance from Cloninger’s concept and Strelau’s RTT traits (positive correlations from r = .73 for Emotional Reactivity to r = .48 for Perseveration, and negative correlations from r = -.57 for Endurance to r = -.51 for Briskness). However, there is not enough evidence to suggest that the two models offer an alternative way of explaining individual differences. According to RTT, temperamental traits are expressed in formal characteristics of behavior (energetic and temporal) and every kind of behavior (irrespective of its content) can be described in the same formal categories. In the Psychobiological Model of Personality the traits are characterized rather by the content or goals of behavior. In this model, in addition to underlining the biological variation of heritable traits, the social, cultural and phenotypical levels of behavior are reflected.

The challenge for psychology is to integrate findings from genetics and environmental (social, biological, chemical) factors, into the study of human behavior and deep understanding of the emergence of different changes in the anatomy, physiology, and chemistry of the nervous system that influence the mental health. Currently, cognitive abilities associated with learning and memory, reasoning, problem solving, and developing relationships are in scope of molecular psychology, which is the study of behavior and its underlying brain systems using the tools of molecular biology. However, studies have demonstrated that DNA sequence variations and rare mutations account for only a small fraction of the risk for inheritance of personality traits and mental illness. The large unaccounted heritability of personality traits and mental health suggest that additional molecular and cellular mechanisms are involved. Various complex gene-environment interactions can lead to different phenotypes. These structural changes may be crucial for the development of mature neural networks that support emotional, cognitive, and social behavior. The generation of different morphology, physiology, and behavioral outcomes from a single genome in response to changes in the environment forms the basis for phenotypic plasticity, which is fundamental to the way organisms cope with environmental variation, navigate the present world, and solve future problems. Epigenetics has major implications for psychology and gives the new answer for the old question- what is the biochemical basis of learning. It is bringing back the leading role of environment and behavior, by including their effects on genome function. In addition, it opens up the possibility of memory being stored in the epigenome, so that our experiences may be embedded in our genome by epigenetic mechanisms. Epigenetics can be described as the study of the complex interactions underlying the development of an organism over its lifetime.

Artykuł omawia wykorzystanie metody triangulacji w naukach społecznych. Triangulacja to strategia zwiększania rzetelności i trafności wyników badań. To zabieg metodologiczny mający na celu uwiarygodnienie zbieranych danych dzięki uwzględnieniu więcej niż dwóch ich źródeł. Polega na włączeniu różnych modeli i narzędzi pomiarowych do badania tego samego zjawiska. Autorki omawiają rolę triangulacji (szczególnie tzw. triangulacji danych) w naukach społecznych. Wskazują, że podstawowe nieporozumienie dotyczące triangulacji polega na oczekiwaniu, że różne metody będą dostarczały takich samych danych i będą prowadzić do takich samych rezultatów. Istoty triangulacji należy upatrywać nie tylko w możliwości zwiększania zaufania do otrzymanych wyników, ale przede wszystkim w możliwości głębszego zrozumienia badanego zjawiska i możliwości generowania nowych sposobów jego wyjaśniania.

This article discusses the use of triangulation in social research. Triangulation is typically a strategy for improving the reliability and validity of research findings. It is a powerful technique, used to verify the findings of a study using data from more than two data sources. Triangulation employs a combination of several research tools or inquiry approaches in the study of the same phenomenon. Positive evidence for the use of triangulation (specifically data triangulation) in social research is presented. A common misunderstanding about triangulation – that different data sources or inquiry approaches should yield the same result – is demonstrated. Triangulation research can serve two purposes: (1) to corroborate findings and more importantly, (2) to gain a holistic view of the phenomenon under study. Triangulation may offer an opportunity for deeper insight into the relationship between the approach to the inquiry and the phenomenon under study, and allow the creation of new ways of understanding.
