Genetic and Environmental Effects on Eudaimonic and Hedonic Well-Being: Evidence from a Post-Communist Culture

Prior behavioral genetic studies in positive psychology were entirely based on data from Western democracies, leaving the question open whether the magnitude of genetic effects on well-being indicators is similar in substantially different societal contexts. The aim of this study, therefore, was to investigate the structure of the genetic and environmental influences on happiness, life satisfaction, meaning in life, optimism, sense of coherence, and general well-being in a non-Western sample. Altogether, 100 monozygotic and 36 same-sex dizygotic twin pairs from Hungary (73 % female; M_age = 43 years, SD = 16 years) participated in the survey. Univariate classical twin modeling (ACE analysis) was performed using structural equation models. Heritability estimates of the positive psychological variables were largely variable, ranging from 0 % (happiness and meaning in life) to 67 % (life satisfaction). Also, estimates for the influence of common environment fell between 0 % (life satisfaction, sense of coherence, and well-being) and 60 % (meaning in life). Unshared environmental influences however, explained a moderate variance of all investigated variables (33–62 %). Most results were in line with previous findings from Western countries; however, some notable differences—e.g., lower hereditary influence for happiness or more robust role of shared environmental effects for optimism—were also established. These findings suggest that the communist and post-communist legacy did not produce drastic differences in the structure of heritability and environmental influences as compared to countries with longer traditions of democracy and economic prosperity.     

Automatic change detection in vision: Adaptation,memory mismatch,or both? II: Oddball and adaptation effects on event-related potentials

In this study we compared the event-related potentials (ERPs) obtained in two different paradigms: a passive visual oddball paradigm and an adaptation paradigm. The aim of the study was to investigate the relation between the effects of activity decrease following an adaptor (stimulus-specific adaptation) and the effects of an infrequent stimulus within sequences of frequent ones. In Experiment 1, participants were presented with different line textures. The frequent (standard) and rare (deviant) texture elements differed in their orientation. In Experiment 2, windmill pattern stimuli were presented in which the number of vanes differentiated the deviant and standard stimuli. In Experiment 1 the ERP differences elicited between the oddball deviant and the standard were similar to the differences between the ERPs to the nonadapted and adapted stimuli in the adaptation paradigm. In both paradigms the differences appeared as a posterior negativity with the latency of 120–140 ms. This finding demonstrates that the representation of a sequential rule (successive presentation of the standard) and the violation of this rule are not necessary for deviancy effects to emerge. In Experiment 2 (windmill pattern), in the oddball paradigm the difference potentials appeared as a long-lasting negativity. In the adaptation condition, the later part of this negativity (after 200 ms) was absent. We identified the later part of the oddball difference potential as the genuine visual mismatch negativity—that is, an ERP correlate of sequence violations. The latencies of the difference potentials (deviant minus standard) and the endogenous components (P1 and N1) diverged; therefore, the adaptation of these particular ERP components cannot explain the deviancy effect. Accordingly, the sources contributing to the standard-versus-deviant modulations differed from those related to visual adaptation; that is, they generated distinct ERP components.
