Although sample-size planning is important for research integrity and useful for designing experiments, it appears to be not yet fully spread in cognitive psychology. The present study examined descriptions for sample-size planning in papers that published in Psychonomic Bulletin & Review and Journal of Experimental Psychology: General. Although some researches determined their sample size without referring to statistical power analysis, they derived the size based on prior research. Not a few researches reported results of power analysis without describing exact values of power and effect sizes and types of targeted effects. To communicate findings more correctly, it should be included descriptions specifying targeted sample sizes and their basis that enables readers to calculate the values irrespective of statistical methods or not. Finally, I discussed the risk of over-emphasizing prior power analysis in peer review.
