Interventions
In the pre-conditioning phase, participants will be exposed to pictures that vary in their emotional (negative, positive) and social (non-social, social) content. For each picture, they are required to indicate their immediate perceived valence (between negative to positive), degree of social motivation (between none to high) on Likert-scales. In the conditioning phase, emotional social pictures will be selected and paired with non-social positive stimuli for trials in random order, for 6 sessions across 3 weeks. In the post-conditioning phase, participants will be asked to evaluate the valence of the stimuli again similar to that in pre-conditioning phase.
