Dandelions, tulips and orchids: evidence for the existence of low-sensitive, medium-sensitive and high-sensitive individuals

Abstract

According to empirical studies and recent theories, people differ substantially in their reactivity or sensitivity to environmental influences with some being generally more affected than others. More sensitive individuals have been described as orchids and less-sensitive ones as dandelions. Applying a data-driven approach, we explored the existence of sensitivity groups in a sample of 906 adults who completed the highly sensitive person (HSP) scale. According to factor analyses, the HSP scale reflects a bifactor model with a general sensitivity factor. In contrast to prevailing theories, latent class analyses consistently suggested the existence of three rather than two groups. While we were able to identify a highly sensitive (orchids, 31%) and a low-sensitive group (dandelions, 29%), we also detected a third group (40%) characterised by medium sensitivity, which we refer to as tulips in keeping with the flower metaphor. Preliminary cut-off scores for all three groups are provided. In order to characterise the different sensitivity groups, we investigated group differences regarding the Big Five personality traits, as well as experimentally assessed emotional reactivity in an additional independent sample. According to these follow-up analyses, the three groups differed in neuroticism, extraversion and emotional reactivity to positive mood induction with orchids scoring significantly higher in neuroticism and emotional reactivity and lower in extraversion than the other two groups (dandelions also differed significantly from tulips). Findings suggest that environmental sensitivity is a continuous and normally distributed trait but that people fall into three distinct sensitive groups along a sensitivity continuum.

Trait Sensitivity, Anxiety, and Personality Are Predictive of Central Sensitization Symptoms in Patients with Chronic Low Back Pain

“…Physical and emotional stressors may be perceived or may remain unconscious and threaten the homeostatic and/or emotional well‐being of the individual . Trait anxiety and trait sensory sensitivity are related to proneness to physiological arousal to stressors . Stress responses involve the autonomic nervous system and the hypothalamic‐pituitary‐adrenal (HPA) axis, in which cortisol is released as part of the anti‐inflammatory response .…”

“…Twenty percent to 30% of individuals in healthy populations have been found to be naturally highly sensitive to environmental and bodily sensory stimuli . Furthermore, healthy populations have been described as being on a spectrum of sensitivity from low to high .…”

‘Every day I worry about something’: A qualitative exploration of children’s experiences of stress and coping

“…All three forms of coping were reported by children in the sample, with varying degrees of success in helping them cope with stress. Individual differences (e.g., personality), sensitivity to context and environment are also factors in the development of resilience (Boyce & Ellis, 2005;Lionetti et al, 2018;Masten, 2014). The success of different coping strategies is situational and person dependent.…”

Measuring Environmental Sensitivity in Educational Contexts: A Validation Study With German-Speaking Students

“…Individuals who are high in SPS have been described as being "particularly sensitive to subtle stimuli, easily overstimulated, prone to 'pause to check' in a novel situation, and prefer[ring] to reflect and revise their cognitive maps after an experience" (Aron, Aron, & Davies, 2005, p. 181). It is suggested that a small proportion of people in the population are more sensitive (e.g., Aron & Aron, 1997; for a recent statistical analysis, see Lionetti et al, 2018).…”
