Submitted questions:

1) "What is the best way to select relevant comparisons for meta-analysis (overall effects versus block effects, interactions)?"

2) "How to generate comparable effect sizes from different reports (t-tests, ANOVAs, means, between subjects, within subjects)?"

3) "Can we get a practical intro into using and entering data into the databases?"

4) "What additional info would be useful in the databases (e.g., details on procedure)?"

5) "When calculating required sample size for your own study based on previous studies, how comparable do the previous studies need to be?"

6) "How many infant studies have been underpowered?"

7) "Do infant researchers nowadays conduct power analyses?"

8) "How can we promote the use of power analyses?"

9) "What is the role of power analyses when the statistical methods are changing so quickly?"

10) "How does one deal with dependencies between data experiments (e.g., two experiments of one study, versus two experiments from two different studies)."

11) "Is there evidence for the decline effect (effect sizes decrease with publication year)?"

12) "How does one take into account uncertainty of effect-size estimates (weigh by study's sample size, standard deviation, ...)?"

13) "How difficult is it to get a meta-analysis published? What are typical reviewer comments?"

Examples:

“How important are meta-analytic approaches, replications, careful, power-analysis-based experimental designs in the field of language development?”

“How can I find out which contrast is easy to discriminate by 6-month-old infants?”
