meta-analysis for a study examining MINDFULNESS, COGNITION, TEXTURE, ENCODING/DECODING

This analysis is a summary of 16 experiments that examined the effect during examination of holding a several textures.   The summary statistic of .510 , with a p-value of 0 (95% CI=.280,.741) suggests a medium and significant effect.  In other words, based on this study students holding a hard ball score better than those holding a soft ball on the tests, using all learning exercises.  An analysis of the moderator shows that learning(decoding) is a significant at .382.   Encoding shows a slight effect size .189, examined separately (encoding/learning).  Ultimately I found that we don’t have a complete story and the model without the moderator is the better predictor of higher scores.
