Moreover, working in a job perceived to be complex positively predicted employees’ proactive work behaviour, but this relationship was largely only evident in employees with a strong awareness of and openness to positive stimuli (AES), but not in those with a lower AES. Employees’ unpleasant arousal from external stimuli (LST) was negatively related to their proactive work behaviour in one of the two studies, and employees’ awareness of and openness to positive stimuli (AES) was largely positively related to proactivity. Two studies based on heterogeneous samples of 215 and 126 employees showed that employees’ tendency to be easily overwhelmed by external stimuli and changes (the dimensions of EOE) was unrelated to their proactive work behaviour. For employees with higher AES, the relationship between job complexity and proactive work behaviour should be stronger. Specifically, when faced with increasing job complexity, employees with higher EOE and LST were assumed to respond less favourably than those with lower EOE and LST. However, because complex jobs also require high information processing and have been found to be positively related to indicators of negative well-being in employees, Schmitt argued that relationships between employees’ perceived job complexity and their engagement in proactive work behaviour are more complex and that employees react differently to job complexity depending on their SPS. Jobs perceived to be complex provide opportunities for self-initiated, change-oriented work behaviours, and previous research has shown that job complexity positively relates to employees’ proactive work behaviour. Job complexity is the level at which work tasks are difficult for individuals to perform and the extent to which a job requires the use of diverse, mentally challenging skills. Moreover, she assumed that the three SPS dimensions would influence how employees respond to job complexity through proactive work behaviour.


One objective of the current study was to examine relationships between SPS and employees’ proactive behaviour at work. However, research that applies the concept to the workplace is largely missing. The scientific knowledge of SPS based on studies with children, adolescents, and adults, as well as non-human animal samples, is also steadily growing.

SPS has attracted increasing societal recognition in recent years due to an increase in self-help literature, coaching, and consulting interventions over the past few years. It is based on the view that individuals differ in their susceptibility to and processing of stimuli, regardless of whether the stimuli are positive or negative. Sensory processing sensitivity (SPS) is a personality trait whereby people exhibit high emotional reactivity and over-arousal, deep information processing, and an keen awareness to environmental subtleties.
