Abstract:
This doctoral dissertation investigates the relationship between eye movement behaviour and vocational interests. The primary objective is to examine how individual personality characteristics–specifically vocational interests–influence visual perception when individuals are presented with complex visual stimuli. This novel approach was selected to address common limitations associated with traditional career assess-ment methods, such as language dependency, social desirability bias, and extreme response tendencies. By utilising eye tracking technology, the research aims to provide a more objective and behaviour-based alternative. Three empirical studies were conducted involving a total of 317 adolescents aged 16 to 19, recruited from German secondary schools and career fairs. Participants viewed two complex visual stimuli, each depicting six representative occupations based on John L. Holland’s RIASEC model. During the task, an eye tracker recorded multiple metrics, including fixation count, dwell time, and saccade count. In addition to the eye tracking procedure, participants completed a standardised vocational interest assessment (AIST-3) and provided image-based ratings. Linear regression analyses were employed to explore the associations between eye tracking variables, image rating scores, AIST-3 scores, and AIST-3 item response times. The findings indicate that the strength of vocational interest is significantly associated with dwell time, fixation count, and image rating scores. In contrast, the assessment of career decision certainty proved more complex; only a weak correlation was observed between saccade count and self-reported certainty. Overall, the results support the existence of fundamental links between eye movements and vocational interest. These findings contribute to the development of a novel and promising methodology for assessing vocational interests through eye tracking technology.
