ALT The study aims to understand how perceptions of dating profiles, in a mobile dating app like Tinder, are influenced by people's judgements of how physically attractive a prospective date is when combined with personality factors. In doing so, it is hoped the study will shed light on what influences decision-making in a fast-paced app environment where daters have limited information. Specifically, the study is particularly interested in whether a diverse sample of sexual orientations have different preferences, as this is currently an under-researched area in social psychology. Participation in this study is entirely voluntary.   To be able to take part in the study, you must be: * Aged 18 years or over   You can withdraw from the study at any time up to the point of submitting the data.
