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…

The purpose of this state-of-the-art review is to provide a general overview of recent research on time distribution and second language (L2) learning with special implications for classroom settings. Several studies have been performed to examine how to best distribute the hours of L2 practice to maximize learning by comparing conditions that…

The aims of this paper are to review research literature on the role that the second language (L2) and foreign language (FL) environments actually play in the development of learners' target language (TL) pragmatic ability, and also to speculate as to the extent to which individual factors can offset the advantages that learners may have by being…

We are grateful to the commentators for providing many stimulating and valuable observations. The main point of our article was to call attention to the overestimation of individual differences correlations in a subset of neuroimaging papers. To structure our discussion of these comments, we list the main points from our paper, note where…

Although comparative judgment methods have a number of distinct advantages over ratings, they share one common problem: On the basis of comparative judgments, it is not possible to recover the origin of item evaluations. One item may be judged more positively than another, but this result does not allow any conclusions about whether either of the…

Reviews some findings obtained through comparisons of dyslexic readers with nondyslexic readers matched by chronological or reading age. Notes some of the problems and pitfalls associated with this approach. Explores the potential of other group comparisons when examining sources of reading difficulty, and discusses individual differences within…

Professional review teams in nine Third World countries assessed a sample of children referred as probable cases (or as controls) from a door to door household survey of 1000+ children aged 3 to 9 years. Examines the criteria used by the teams in determining whether or not the children should be classified as severely mentally handicapped. (RWB)
