Research synthesis techniques such as systematic reviews and metaanalyses have become standard methods for aggregating the results from thematically related research in psychology. In this Hotspots issue, leading researchers describe state of the art systematic reviews and meta-analyses on topics currently being debated in psychology. Besides substantive research questions, methodological advances in research synthesis methods are also addressed.

State-of-the-art reviews of hot topics in psychology 2018 This Hotspots issue showcases some of the vibrant meta-analytic research activity that is underway in psychology, including not only applications of state-of-the-art meta-analytic methods to a steadily increasing number of substantive research fields but also methodological innovations to address challenges of meta-analytic research. It includes a ground-breaking approach for identifying hotspot topics using latent Dirichlet allocation to identify research topics of particular significance over time, a meta-analysis investigating the cross-cultural comparability of a well-established psychometric instrument capturing self-esteem, as well as replications and extensions of previous meta-analyses and a methodological contribution on effect size estimation.

Cutting-edge meta-analyses and research methodology in psychology. This third collection of Hotspots in Psychology presents state-of-the-art meta-analytic research in psychology. It features the first systematic literature review of the empirical evidence regarding stability and change of values in adults, as well as meta-analyses examining the effects of descriptive and injunctive norms on consumer decision making, how ethical leadership shapes organizational citizenship behavior, and whether interparental relationship quality differs between parents of children with or without ADHD. Methodological contributions include a systematic review of questionable research practices, an exploration of the role of researchers analytic flexibility when meta-analyzing data using specification-curve analysis and multiverse analysis, as well as a new approach to improving the quality of inferences drawn from funnel plots.

Methodological advances for meta-analyses and state-of-the-art research syntheses in psychology.The seventh volume of "Hotspots in Psychology" features research on methodological advances in meta-analyses of psychological applications and highlights research syntheses that have a special relevance to the field. Methodological contributions explore new approaches of interest within the field of psychology on how to treat potential measurement errors in MASEM and how to apply the metaplot - a new descriptive visual tool as an alternative to the oftencriticized funnel plot.Other contributions explore hotly debated topics or areas that have generated high levels of research activity, including a metaanalysis on the effects of meditation interventions. Furthermore, an application with large-scale panel data in educational research examines the commitment of students to their study program andstudy success over time. Using exceptional model mining, the study demonstrates a new framework to model structural heterogeneity. A systematic review on screening automation tools introduces existing screening tools and reviews evidence on their performance. The results provide guidance on how to reduce the screening workload when doing a systematic review.
