In peer-mediated intervention (PMI), peers act as agents of intervention. Previous reviews in this area have not addressed the effectiveness of using PMI with children with autism who are minimally verbal. Following a systematic search, we reviewed 25 studies where PMI was used to increase communication in minimally verbal participants. The…

Dimensional comparisons between math and verbal achievements affect students' academic self-concepts by increasing (decreasing) students' self-concept in the subject with their intraindividual higher (lower) achievement. Dimensional comparison theory assumes that dimensional comparisons are also triggered by external influences. The present…

The internal/external (I/E) frame of reference entails high, positive association of mathematics and verbal achievements with matching academic self-concepts but negative or near-zero correlation with their nonmatching self-concepts. This study aimed to extend the traditional I/E model by contrasting the mathematics domain with two foreign…

Peer support interventions have mostly neglected the domain specificity of intervention effects. In two studies, the present investigation examined the domain specificity of peer support interventions targeting specific domains of self-concept. In Study 1, participants ("n" = 50) who had received an academically oriented peer support…

In 2 field experiments, we relied on the very features of real testing situations--where both math and verbal tests are administered--to examine whether order of test administration can, by itself, create vs. alleviate stereotype threat (ST) effects on girls' math performance. We predicted that taking the math test before the verbal test would be…
