We are currently working on a meta-analysis concerning the role of sleep on the consolidation of emotional memory. To include as many samples as possible and to control for the potential impact of publication bias, we are looking for unpublished or not yet published data on sleep and its impact on the consolidation of emotional memories. Data could be relevant if the following criteria are fulfilled: 1) The study includes a pre-sleep learning phase in which neutral and emotional stimuli are presented individually. Subsequently the participants have a sleeping opportunity for the night or parts of the night, this could be in the lab or at home. There is an assessment of item memory or associative memory within 48 hours after the initial learning phase. Studies do not necessarily need to include a wake control group. 2) Studies should report an interaction effect comparing post-sleep memory performance for emotional and neutral stimuli. We are able to work with effect sizes (d or Hedge’s g) as well as raw data if you prefer to share your data with us in this form (of course for this use only). If you send us any unpublished effect sizes or data, it is up to you to decide if you want to be mentioned in the meta-analysis as the author or if you would like to remain anonymous. If you have any suitable data for us or if you are not sure whether your study fits into the meta-analysis, please do not hesitate to send an e-mail to [email protected].
