| Abstract: | 89 10–12 yr olds completed the Test Anxiety Scale for Children annually for 3 yrs, and the 3 measurements were transformed into average, linear, and quadratic components by using orthogonal polynomials. These components provided a developmental profile for each child and were used in a hierarchical multiple regression analysis to predict arithmetic performance under 1 of 2 treatment conditions, a mixed condition involving failure under time pressure and a success condition involving no time pressure. Developmental profile interacted with treatment to predict task performance. (5 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
