Heritability of proneness for psychological flow experiences

• Flow is a subjective experience of high but effortless attention, loss of self-awareness, control, and enjoyment that can occur during active performance of challenging tasks. Proneness to experience flow is associated with personality, specifically with low neuroticism and high conscientiousness. We investigated genetic and non-genetic influences on flow proneness in 444 adult twin pairs. Data were collected using an on-line administration of the Swedish Flow Proneness Questionnaire, which includes separate scales for flow proneness in three major domains of life: work, maintenance, and leisure. We found moderate (.29-.35) heritabilities for the flow scales. Twin correlations as well as multivariate modeling suggested non-additive genetic influences. Genetic influences were almost entirely shared for the three flow scales and genetic correlations between the scales were very high (.81-.97), suggesting that the same genes influence flow proneness independently of domain. Non-shared environmental influences, in contrast, were largely specific to each flow scale. We conclude that an individual's general proneness to experience flow is influenced by the same genetic factors regardless of domain, and these may be associated with personality traits that are conducive to flow. In addition, specific environmental factors appear to be of importance for within-individual differences in flow proneness in different domains. (C) 2012 Elsevier Ltd. All rights reserved.
