Research on the question of creative benefit accompanying dyslexia has produced conflicting findings. In this meta-analysis, we determined summary effects of mean and variance differences in creativity between groups with and without dyslexia. Twenty studies were included (n = 770 individuals with dyslexia, n = 1,671 controls). A random-effects…

Bjorklund and Kipp (1996) hypothesized that due to selection processes operative during human evolution, females have an inborn advantage over males in the ability to suppress inappropriate responses on tasks in the behavioral and social domains. To test this hypothesis, a meta-analysis was conducted on gender differences on simple delay tasks in…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

Children seem to be relatively delayed in their comprehension of the verbal "be"-passive in English, compared to their acquisition of other constructions of object-movement such as "wh"-questions and unaccusatives. Prior work has found that children's performance on these passives can be affected by the verb's lexical…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

We examined 3- to 6-year-old children's understanding of their own and another's false beliefs in two experiments using diverse deceptive box and unexpected transfer tasks. Tasks in the first experiment required the child to think about an absent person's responses to questions, whereas those in the second experiment used a confederate present…
