Assessment of natural reward responsiveness
In an experimental laboratory session, participants were presented with images representing natural rewards or neutral cues. On each trial, participants were first shown a fixation cross for 500 ms, followed by 250–500 ms jittered blank screen and then an image and instruction label for 5000 ms. Across 64 trials, cues were presented in a randomized, event-related design.Participants were instructed to View or Regulate responses to natural reward stimuli. On View trials, participants were instructed to simply attend to images of naturally rewarding stimuli (e.g. social affiliation, natural beauty, athletic victories, etc.) validated in prior studies (Garland, Bryan, Nakamura, Froeliger, & Howard,
