Sensation seeking

Sensation seeking is a personality trait defined by the search for experiences and feelings, that are "varied, novel, complex and intense", and by the readiness to "take physical, social, legal, and financial risks for the sake of such experiences." Risk is not an essential part of the trait, as many activities associated with it are not risky. However, risk may be ignored, tolerated, or minimized and may even be considered to add to the excitement of the activity. The concept was developed by Marvin Zuckerman of the University of Delaware. In order to assess this trait he created a personality test called the Sensation Seeking Scale. This test assesses individual differences in terms of sensory stimulation preferences. So there are people who prefer a strong stimulation and display a behavior that manifests a greater desire for sensations and there are those who prefer a low sensory stimulation. The scale is a questionnaire designed to measure how much stimulation a person requires and the extent to which they enjoy the excitement. Zuckerman hypothesized that people who are high sensation seekers require a lot of stimulation to reach their Optimal Level of Arousal. When the stimulation or sensory input is not met, the person finds the experience unpleasant.

Sensation-seeking can be divided into 4 traits:

The most recent version of the Sensation Seeking Scale (SSS-V) has demonstrated moderate validity and reliability. It has been adapted for use with children.

Zuckerman began researching the personality trait he came to call "sensation seeking" in 1969. Zuckerman argues that sensation-seeking is one of a handful of "core traits" that can be used to describe human personality. Although, other researchers including Eysenck, and Costa and McCrae considered the trait to be related to extraversion, factor-analytic studies conducted by Zuckerman suggested that sensation seeking is relatively independent of other major dimensions of personality. A number of studies have found positive correlations between sensation seeking, especially the experience seeking component, and openness to experience. Additionally,negative correlations have been found between agreeableness from the NEO-PI-R and total sensation seeking, and the boredom susceptibility and disinhibition subscales. The honesty-humility factor of the HEXACO model has been shown to be negatively correlated with sensation seeking and risk taking behaviors.
