Meta Analysis Teams
Multiple Behaviors project
We meta-analyze several hundred effect sizes from studies with a behavioral dependent measure in which individuals are primed with words, metaphors, or other stimuli related to a concept to test theoretical and methodological moderators of these effects, in addition to whether publication bias can account for the results.

Will eating raw onions once a day for 3 days protect me from Ebola? This was a question posed to the health workers at the free Ebola hotline in Guinea. This is one of the examples of misinformation that caused many Ebola deaths in 2014. When we receive incorrect information about an event it can lead to memory distortion, known as the misinformation effect. Such an effect may continue to influence our decision and beliefs even after subsequent information correction. The misinformation effect (ME) and the continued influence effect (CIE) can exert a major impact on decision making, cognition, and behaviors. Despite the continuous efforts to scrutinize these effects in various areas of research, no synthesis, to our knowledge, has provided a comprehensive picture of the misinformation effect (ME) and the continued influence effect (CIE). This meta-analysis will provide the first evidence regarding the effect sizes of these effects. More importantly, this project will examine factors that strengthen or mitigate CIE, such as motivated cognition and the development of supportive arguments. Furthermore, we will test moderators to scrutinize whether the study design and demographics of the participants are likely to explain the differences in CIE. Implications for integrating the mitigating factors of CIE into formulation of theories, research design, and programs will be discussed.
Self Control project
Theories of internalizing psychopathology emphasize the role of perseverative thinking, not only as a correlate, but as a risk factor in both the development and maintenance of psychopathological symptoms. Specifically, research has shown that depressed and anxious individuals tend to engage in a pattern of repetitive negative thinking about the past and the future. Another factor that can shed some light on the association between these two variables is self-control. Facets of self-control are shown to negatively correlate with both perseverative thinking and psychopathology. However, there have been relatively few studies that have simultaneously tested the direct and indirect effects of self-control and perseverative thinking on depression and anxiety. This meta-analysis thus tests two competing theories to better understand how self-control and perseverative thinking relate in predicting psychopathology, and if one may be the driving force behind these associations.
