Natural environments have been shown to trigger psychological and physiological restoration in humans. A new framework regarding natural environments restorative properties is proposed. Conditioned restoration theory builds on a classical conditioning paradigm, postulating the occurrence of four stages: (i) unconditioned restoration, unconditioned positive affective responses reliably occur in a given environment (such as in a natural setting); (ii) restorative conditioning, the positive affective responses become conditioned to the environment; (iii) conditioned restoration, subsequent exposure to the environment, in the absence of the unconditioned stimulus, retrieves the same positive affective responses; and (iv) stimulus generalization, subsequent exposure to associated environmental cues retrieves the same positive affective responses. The process, hypothetically not unique to natural environments, involve the well-documented phenomenon of conditioning, retrieval, and association and relies on evaluative conditioning, classical conditioning, core affect, and conscious expectancy. Empirical findings showing that restoration can occur in non-natural environments and through various sensory stimuli, as well as findings demonstrating that previous negative experience with nature can subsequently lower restorative effects, are also presented in support of the theory. In integration with other existing theories, the theory should prove to be a valuable framework for future research.

Existing research from the Netherlands suggests that bicycle attitudes and behaviour affect each other, but bicycle behaviour affects attitude more than vice versa (Kroesen et al., 2017). We conducted a quasi-replication study using existing datasets (n=972) with slightly different operationalisations and timeframes in a Norwegian context. Using two variations of a structural equation model, we confirm this bidirectional effect, though our findings show a considerably stronger influence of attitudes on behaviour than the reverse.

This study examines the relationships between traffic safety innovations, innovation culture, and safety culture in four Norwegian county authorities three years after a comprehensive structural reform. Following the reform, the county authorities had to establish new organisations, routines, and systems. The study is based on qualitative interviews (N = 42) and a quantitative survey (n = 392) among people who work with traffic safety and/or mobility in the county authorities. The qualitative results show in particular that the respondents have gained new perspectives on traffic safety as a result of being co-organised with new professional groups. Additionally, we see examples of new methods and new forms of collaboration in traffic safety being implemented. The survey results show statistically significant differences between the county authorities' scores on an index for traffic safety innovations. County authorities' scores on this index is predicted by the county authorities' innovation culture, which in turn is predicted by safety culture. This indicates that innovation culture should be understood as an aspect of a learning safety culture. We find statistically significant differences between county authorities with respect to how demanding the organizational changes related to the regional reform have been for the county authorities studied. The results from this study can also be useful for change processes in other organisations.
