The temperament trait of environmental sensitivity is associated with connectedness to nature and affinity to animals.

Heightened sensitivity to the environment characterizes approximately 30% of the population and is associated with a higher reactivity, positive or negative, to the surrounding environment. Little attention has been devoted to study the association between this trait and the response to nature and animals, despite the potential benefits of the natural environment for highly sensitive individuals. In the present two studies (N = 241, 83% female, age M = 37.43, SD = 13.5; N = 144, 92% female, age M = 39.9, SD = 13.1) we assessed the association of sensory processing sensitivity (SPS), measured with the Highly Sensitive Person scale, with nature and animal affinity. In both studies, we found SPS to predict higher connectedness to nature. In addition, whilst there was no association between high SPS and attachment to pets in Study 1, in Study 2 SPS was predictive of a higher animal affinity, assessed in terms of stewardship and protection of animals. The present studies provide the first quantitative empirical evidence that highly sensitive individuals are more connected with nature and animals, therefore opening the possibility to explore nature based solutions to improve the quality of life in individuals scoring high in SPS.
