1-041 - Big Ideas to Tackle Small Samples

Thu, March 21, 9:30 to 11:00am, Hilton Baltimore, Floor: Level 2, Key 1

Session Type: Paper Symposium

Integrative Statement

Collecting adequate samples is a key to running well-powered research studies, and improving the replicability of research (Open Science Collaboration, 2015; cf. Gilbert et al., 2016; Anderson et al., 2016). However, doing so can be challenging in research with children, especially with special populations due to recruitment difficulties (e.g., infants, bilingual children; c.f., Frank et al., 2017). Recent work suggests that many infant studies, for example, are underpowered due to small sample sizes (Oakes, 2017). This symposium presents three creative approaches to gather larger samples of participants than is typically done in single-lab studies.

Talk 1 discusses data collection in museum settings, and how such partnerships can benefit both researchers and the community. Talk 2 presents results from a multi-lab infant study on gaze following in monolinguals and bilingual infants involving 18 labs internationally (projected N = 640), and how bringing together researchers in one collaboration can inspire new collaborative efforts. Talk 3 promotes meta-analysis as a way to aggregate across studies that each have smaller samples, to obtain more robust estimates of effect sizes, and to generate new theoretical insights that could not be gleaned from a single study. Finally, advantages, disadvantages and challenges of each of these approaches will be discussed.Together, we expect these presentations will generate important discussions of big new ideas for conducting well-powered and reproducible developmental science.
