Patterns of Cognitive Strengths and Weaknesses and Relationships to Math Errors

This study investigated cognitive patterns of strengths and weaknesses (PSW) and their relationship to patterns of math errors on the Kaufman Test of Educational Achievement (KTEA-3). Participants, ages 5 to 18, were selected from the KTEA-3 standardization sample if they met one of two PSW profiles: high crystallized ability (Gc) paired with low processing speed/long-term retrieval (Gs/Glr; n = 375) or high Gs/Glr paired with low Gc (n = 309). Estimates of Gc and Gs/Glr were based on five KTEA-3 subtests that measure either Gc (e.g., Listening Comprehension) or Gs/Glr (e.g., Object Naming Facility). The two groups were then compared on math error factors. Significant differences favored the High-Gc group for factors that measure math calculation, basic math concepts, and complex computation. However, the two groups did not differ in their errors on factors that measure geometry/measurement or simple addition. Results indicated that students with different PSW profiles also differed in the kinds of errors they made on math tests.

Do Cognitive Patterns of Strengths and Weaknesses Differentially Predict Errors on Reading, Writing, and Spelling?

This study investigated the relationship between specific cognitive patterns of strengths and weaknesses (PSWs) and the errors children make in reading, writing, and spelling tests from the Kaufman Test of Educational Achievement–Third Edition (KTEA-3). Participants were selected from the KTEA-3 standardization sample based on five cognitive profiles: High Crystallized Ability paired with Low Processing Speed and Long-Term Retrieval (High Gc), Low Crystallized Ability paired with High Processing Speed and Long-Term Retrieval (High Gs/Glr), Low Orthographic Processing (Low OP), Low Phonological Processing (Low PP), and Low Phonological Processing paired with Low Orthographic Processing (Low PP_OP). Error factor scores for all five groups were compared on Reading Comprehension and Written Expression; the first four groups were compared on Letter & Word Recognition, Nonsense Word Decoding, and Spelling, and the first three groups were compared on Phonological Processing. Significant differences were noted among the patterns of errors demonstrated by the five groups. Findings support the notion that students with diverse cognitive PSWs display different patterns of errors on tests of academic achievement.

Semantic and Phonological Ability to Adjust Recoding: A Unique Correlate of Word Reading Skill?

ABSTRACT This study addresses whether reading involves a process termed semantic and phonological ability to adjust recoding (SPAAR). It was hypothesized that SPAAR helps readers link inaccurate pronunciations to lexical entries (e.g., spynitch to spinach). Psychometric properties of the Mispronunciation Correction Task (MCT), a measure of SPAAR, were investigated using a sample of 206 elementary-age children. The 25-item MCT appeared to measure a single construct, and the items discriminated well across the range of ability. Based on a sample of 94 children, construct validity analyses indicated that phonological awareness and decoding skill predicted MCT performance. Hierarchical regressions were used to test the relationship between SPAAR and word reading. After controlling for other skills, SPAAR showed a relationship with both timed and untimed word reading. Phonological awareness did not. These data suggest that SPAAR may be a reading-related ability involving phonological processing and some form of semantic processing.

Patterns of Strengths and Weaknesses on the WISC-V, DAS-II, and KABC-II and Their Relationship to Students' Errors in Oral Language, Reading, Writing, Spelling, and Math.

This study investigated the relationship between specific cognitive patterns of strengths and weaknesses and the errors children make on oral language, reading, writing, spelling, and math subtests from the Kaufman Test of Educational Achievement–Third Edition (KTEA-3). Participants with scores from the KTEA-3 and either the Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V), Differential Ability Scales–Second Edition (DAS-II), or Kaufman Assessment Battery for Children–Second Edition (KABC-II) were selected based on their profile of scores. Error factor scores for the oral and written language tests were compared for three groups: High Gc paired with low processing speed, long-term memory, and/or reasoning abilities; Low Gc paired with high speed, memory, and/or reasoning; and Low orthographic and/or phonological processing. Error factor scores for the math tests were compared for three groups: High Gc profile; High Gf paired with low processing speed and/or long-term memory; and Low Gf paired with high processing speed and/or long-term memory. Results indicated a difference in Oral Expression and Written Expression error factor scores between the group with High Gc paired with low processing speed, long-term memory, and/or reasoning abilities; and the group with Low Gc paired with high speed, memory, and/or reasoning.

Biological Gender Differences in Students’ Errors on Mathematics Achievement Tests

This study investigated developmental gender differences in mathematics achievement, using the child and adolescent portion (ages 6-19 years) of the Kaufman Test of Educational Achievement–Third Edition (KTEA-3). Participants were divided into two age categories: 6 to 11 and 12 to 19. Error categories within the Math Concepts & Applications and Math Computation subtests of the KTEA-3 were factor analyzed and revealed five error factors. Multiple ANOVA of the error factor scores showed that, across both age categories, female and male mean scores were not significantly different across four error factors: math calculation, geometric concepts, basic math concepts, and addition. They were significantly different on the complex math problems error factor, with males performing better at the p < .05 significance level for the 6 to 11 age group and at the p < .001 significance level for the 12 to 19 age group. Implications in light of gender stereotype threat are discussed.

Do the Kinds of Achievement Errors Made by Students Diagnosed With ADHD Vary as a Function of Their Reading Ability

A large body of research has documented the relationship between attention-deficit hyperactivity disorder (ADHD) and reading difficulties in children; however, there have been no studies to date that have examined errors made by students with ADHD and reading difficulties. The present study sought to determine whether the kinds of achievement errors made by students diagnosed with ADHD vary as a function of their reading ability. The participants in this study were 91 students in the ADHD clinical validity standardization sample of the Kaufman Test of Educational Achievement–Third Edition (KTEA-3), as well as a control group of 63 students selected from the larger standardization sample. Students with ADHD and reading difficulties demonstrated a statistically significant greater amount of errors across tests of academic achievement. Findings from the study are discussed within the context of past research, as well as implications for the field of school psychology and practitioners.

Investigating Patterns of Errors for Specific Comprehension and Fluency Difficulties

Although word reading has traditionally been viewed as a foundational skill for development of reading fluency and comprehension, some children demonstrate “specific” reading comprehension problems, in the context of intact word reading. The purpose of this study was to identify specific patterns of errors associated with reading profiles—basic reading difficulties (BRD), reading fluency difficulties (RFD), reading comprehension difficulties (RCD), and typical readers (total n = 821). Results indicated significant differences between the groups on most error factors. Post hoc analyses indicated there were no significant differences between the RFD and RCD groups, but these groups demonstrated different patterns of significant weakness relative to typical readers. The RFD group was weaker in spelling and oral expression whereas the RCD group demonstrated difficulties in writing mechanics and listening comprehension. These findings indicate that comprehension deficits cannot be attributed only to fluency difficulties and that specific reading difficulties may translate to other aspects of achievement.

Initial Examination of the BRIEF2 in Clinically Referred Children With and Without ADHD Symptoms

Objective: Clinical utility of the Behavior Rating Inventory of Executive Function, Second Edition (BRIEF2) was examined in 1,381 clinically referred youth (62.5% male, 5 to 18 years) with and without ADHD symptoms. Method: Participants included children with restricted inattentive symptoms (IA only), restricted hyperactivity/impulsivity symptoms (HI only), symptoms in both domains (Combined), and non-ADHD clinical comparison. Results: Greater hyperactivity (Combined, HI only) was associated with higher Behavior Regulation (BRI) and Emotion Regulation (ERI) scores, whereas greater inattentiveness (IA only, Combined) was associated with higher Cognitive Regulation scores. Effect sizes were largest for Inhibit, Working Memory, and Organization of Materials scales; these scales discriminated children with and without ADHD symptoms and restricted inattentive and hyperactive presentations. Conclusion: The BRIEF2 distinguishes associated features of ADHD and the day-to-day executive impact. Sensitivity was consistently poorer than specificity. The referred nature of the sample and examination of restricted presentations suggest additional work is needed to examine whether ERI and BRI are dissociable.

A systematic review of trauma screening measures for children and adolescents.

Traumatized youth are at an increased risk of a host of negative academic and psychoeducational outcomes. Screening and identification of students who experience potentially traumatic events may help schools provide support to at-risk students. In light of this, the current study examines the availability and use of trauma screening measures to detect early indicators of risk among youth in schools. A systematic review was conducted to identify measures available to screen children and youth for trauma exposure and/or symptoms, as well as the associated psychometric properties to support each instrument’s applied use in schools. Eighteen measures met inclusion criteria, which consisted primarily of student self-report rating scales and clinical interviews. While many instruments measure the symptomology or exposure to trauma among children and youth, very little psychometric evidence was available to support the use of these measures in schools. Additional research is needed to endorse and expand the use of trauma screening measures in schools.

Evaluating the Effects of Supplemental Reading Intervention Within an MTSS or RTI Reading Reform Initiative Using a Regression Discontinuity Design

A large body of research supports the efficacy of small group reading interventions for students in Grades K through 3. However, there are few studies evaluating the effects of supplemental Tier-2 intervention implemented within a response to intervention (RTI) or multitiered systems of support (MTSS) framework. The purpose of this study was to evaluate the effects of providing Tier-2 supplemental intervention to students in Grades 1 through 3 identified as experiencing reading difficulties (n = 318) in four elementary schools across four different school districts that were selected to participate in a state MTSS initiative. The supplemental intervention was evaluated using a regression discontinuity design, and results indicated statistically significant overall effects on measures of phonemic awareness and word decoding and no discernable effects on reading fluency and comprehension. Results suggest that supplemental reading intervention implemented within MTSS frameworks can impact key reading outcomes when intervention significantly increases instructional intensity.
