Social media challenge several established concepts of memory research. In particular, the day-to-day mundane discourse of social media blur the essential distinction between commemorative and non-commemorative memory. We address these challenges by presenting a methodological framework that explores the dynamics of social memory on various social media. Our method combines top-down data mining with a bottom-up analysis tailored to each platform. We demonstrate the application of our approach by studying how the Holocaust is remembered in different corpora, including a dataset of 5.3 million Facebook posts and comments collected between 2015 and 2017 and a 5 million Tweets and Retweets dataset collected in 2021. We first identify the mnemonic agents initiating the discussion of the memory of the Holocaust and those responding to it. Second, we compare the macro-rhythms of Holocaust discourse on the two platforms, identifying peaks and mundane discussions that extend beyond commemorative occasions. Third, we identify distinctive language and cultural norms specific to the memorialization of the Holocaust on each platform. We conceptualize these dynamics as ‘Mnemonic Markers’ and discuss them as potential pathways for memory researchers who wish to explore the unique memory dynamics afforded by social media.

The goal of this paper is to review assessment research of bipolar disorder in children and adolescents. The review addresses numerous themes: the benefits and costs of involving clinical judgment in the diagnostic process, particularly with regard to diagnosis and mood severity ratings; the validity of parent, teacher, and youth self-report of manic symptoms; how much cross-situational consistency is typically shown in mood and behavior; the extent to which a parent's mental health status influences their report of child behavior; how different measures compare in terms of detecting bipolar disorder, the challenges in comparing the performance of measures across research groups, and the leading candidates for research or clinical use; evidence-based strategies for interpreting measures as diagnostic aids; how test performance changes when a test is used in a new setting and what implications this has for research samples as well as clinical practice; the role of family history of mood disorder within an assessment framework; and the implications of assessment research for the understanding of phenomenology of bipolar disorder from a developmental framework.We thank the families who participated in this program of research.
