This study is to understand how the presentation of information on social media influences processing and recall of information, particularly in relation to modified risk tobacco products. Participants will see a social media site where either (a) the topic of discussion varies between each post or (b) posts on the same topic are grouped together. They will then be asked to recall information about the posts they saw on the site.

Participants are assigned to one of two between-group conditions: either receiving a high mixed presentation of content in the social media feed (where the topic varies from post to post), or a low mix of presentation of content in the social media feed (where the topic does not vary).
Additionally, two further between-subject groups will be created by independently examining effects among current and former smokers.
