Group differences and individual classification accuracy associated with letter/word oddity problems.

The ability of 27 pairs of mildly mentally retarded and normally achieving 6- through 8-year-old students to apply an oddity rule to an experimental set of letter and word oddity problems was assessed. The mildly retarded group evidenced a markedly lower level of performance on all five experimental oddity problems, but they did evidence successful generalization to oddity arrays that visually were very different from those used in training. High levels (greater than 90%) of sensitivity, specificity, positive predictive accuracy, and negative predictive accuracy were observed using only six cards. Only slightly lower (greater than or equal to 85%) values were obtained when using a cut-off score. This subset of six cards is, therefore, an excellent candidate for inclusion in a cognitive preschool screening test being developed for the early detection of children with mild mental retardation.

Classification of normally achieving and mildly mentally retarded students on the basis of their oddity transfer performance.

Forty mildly retarded, 6- through 9-year-old children selected from educable mentally retarded (EMR) classes and 40 normally achieving students of the same age were pretrained on the oddity solution and then given eight different, six-trial oddity transfer problems. A higher level of transfer was associated with the older (8- and 9-year-olds) and with the normally achieving students. The students' performance on the oddity transfer trials was used to classify them into their two respective groups. High levels of classification accuracy were observed in the discriminant function analyses. On both the group comparison and the individual student classifications, all eight oddity types were sensitive to differences between the normally achieving and mildly retarded grade school students.
