Academic and cognitive abilities in children of parents with bipolar disorder: a test of the nonverbal learning disability model.
It has been hypothesized that children who are at genetic risk to develop bipolar disorder demonstrate deficiencies consistent with the syndrome of nonverbal learning disabilities (NLD); however, this hypothesis has never been tested directly. In the present study, a group of at-risk children (AR group; N = 28) was compared to a demographically matched control group of children of healthy parents (HC group; N = 24) for evidence of a constellation of features associated with NLD. Some characteristic features of NLD were evident, including significant Verbal IQ (VIQ) > Performance IQ (PIQ) discrepancies and psychomotor deficits. However, academic deficiencies in mechanical arithmetic relative to reading and spelling abilities were not demonstrated. These findings replicate and extend the current literature on the cognitive functioning of children of parents with Bipolar disorder (BPD). The results, however, do not support the presence of NLD in these children.

What do students with learning disabilities think when their general education teachers make adaptations?
The purpose of this study was to investigate the perceptions of mainstreamed students with learning disabilities (LD) regarding adaptations (e.g., altering tests, homework, assignments, instruction) made by general education teachers. Furthermore, their responses were compared with those of low achieving (LA) and average/high achieving (A/HA) classmates. One hundred seventy-nine students participated in this study: 60 mainstreamed students with LD, 59 low achieving students, and 60 average/high achieving students. Students were selected from 60 teachers' classrooms (20 elementary, 20 middle school, and 20 high school). Results from the elementary level indicate that students with LD differ from their LA and A/HA classmates in that the former indicate a stronger preference for opportunities to work in groups with different students, and prefer the teacher to make adaptations when they have difficulty learning. High school and middle school students from both the LA and A/HA groups, but not the LD group, preferred the teacher who made no adaptations in homework and textbooks. Discussion focuses on the role of students' perceptions in teacher decision making.

Attentional deficits of learning-disabled children: effects of rewards and practice.
This study investigated the effects of rewards and practice on the attentional task performance of learning-disabled (LD) and normally achieving children. Contingent feedback and rewards resulted in faster but less accurate performance by the LD children. Despite the speed-accuracy trade-off, the LD children still responded more slowly than the controls. However, limited practice on the tasks resulted in significantly improved performance, such that the groups performed similarly. Poorer performance of LD children on their first encounter with laboratory measures of attention may be due to inefficient strategies rather than to actual deficits in ability to attend.

Comparison of scores on WISC-III and WISC--R of urban learning disabled students.
Wechsler Intelligence Scale for Children-III IQs and Wechsler Intelligence Scale for Children--Revised IQs of 16 preadolescents who were learning disabled, urban students (14 black) receiving special education services were compared. Analyses indicated lower mean WISC-III IQs, correlations of .57, .74, and .72 between scores on Full, Verbal, and Performance Scales, respectively, and significant correlations of .44 to .80 between respective sets of subtests. Exceptions were Information (.34), Similarities (.30), and Picture Arrangement (.15). These results suggest that the WISC-III may compare favorably with the WISC--R, if replicated with a substantial group.

Hemispheric processing and cognitive styles in learning-disabled and normal children.
A paradigm of specialized brain hemisphere processing abilities was used to test cognitive skills and cognitive style in "learning-disabled" (LD) and "normal" children. Results indicate that (1) verbal ability is not a unitary factor, and LD children are deficient in only some aspects of verbal ability; (2) the LD group perform as well as the control group on right-hemisphere tests; (3) LD boys are more field sensitive (field dependent) than the control boys; (4) LD children may be attempting to use a nonverbal information processing mode to deal with academic tasks. The need for information on nonverbal processing skills in order to aid verbal processing is discussed.

Tiers of intervention in responsiveness to intervention: prevention outcomes and learning disabilities identification patterns.
Response to Intervention (RTI) models have attracted great attention as an alternative to traditional methods used for identifying students with learning disabilities. A major feature of this approach is the implementation of academic interventions in general education and measuring the student's response to those interventions. A common question that needs to be addressed is the number of stages or tiers of intervention necessary in the Response to Intervention model. This article reviews three studies of RTI that investigate the RTI tiers. Sharon Vaughn and Rollanda O'Connor report on studies using the Standard Protocol approach to RTI. David Tilly reports on using the Problem Solving Model as an RTI model. This article summarizes the results of these three investigations.

Subcategory learning in normal and language learning-disabled adults: how much information do they need?
PURPOSE: The purpose of this experiment was to determine if nonreferential morphophonological information was sufficient to facilitate the learning of gender subcategories (i.e., masculine vs. feminine) in individuals with normal language (NL) and those with a history of language-based learning disabilities (HLD). METHOD: Thirty-two adults listened for 18 min to a familiarization set of Russian words that included either 1 (single-marked) or 2 (double-marked) morphophonological markers indicating gender. Participants were then tested on their knowledge of both trained and untrained members of each gender subcategory. RESULTS: Testing indicated that morphophonological information is sufficient for lexical subcategory learning in both NL and HLD groups, although the HLD group had lower overall accuracy. The HLD group benefited from double-marking relative to single-marking for subcategory learning. CONCLUSION: The results demonstrated that learning through implicit mechanisms occurred after a relatively brief exposure to the language stimuli. In addition, the weaker overall learning by the HLD group was facilitated when multiple cues to linguistic subcategory were available in the input group members received.

Hemispheric asymmetry and recategorized WISC-R patterns in learning-disabled and nondisabled children.
The relationship between hemispheric processing and recategorized WISC-R patterns (spatial strengths and depressed Acquired Knowledge scores) in 14 learning-disabled and 14 nondisabled boys was examined. A genetic-prenatal hormonal basis appears most plausible.

Computer-based study strategies for students with learning disabilities: individual differences associated with adoption level.
This article reports results from a study of the use of technology to support students with learning disabilities in the use of effective study strategies. Thirty secondary students were given laptop computers and taught a variety of computer-based study strategies designed to facilitate information recording, organization, and manipulation. Results suggest that students adopted this innovation at three levels: (a) Power Users (skilled, independent users, integrating the computer into their schoolwork); (b) Prompted Users (skilled computer users, but requiring prompting); and (c) Reluctant Users (having limited knowledge and working only under supervision). Intelligence and reading test scores were associated with adoption levels in a statistically significant way.

Responses and needs in a changing situation: staff who work with people with learning disability.
Questionnaires were sent to residential care staff working with people with learning disability both in hospital and community settings, to explore any changes resulting from implementation of the policy of care in the community. Information was obtained on the current job situation of staff, their opinions on the effect of the policy of care in the community, their training needs, and perceived job prospects for the future. Findings for staff working in a hospital setting are compared with those of staff working in the community and discussed in the context of changing demands and conditions.

Learning disabilities: the challenge for nursing.
Over the past 10 years, people with learning disabilities have moved out of institutions and into the community. Their care is now seen as a social, rather than a health, issue. But there is a danger that this may lead to their general health needs being overlooked. Specialist registered mental handicap nurses are ideally suited to bridging this gap, possibly in partnership with primary health care teams.

Mental flexibility and planning skills in children and adolescents with learning disabilities.
Mental flexibility (skill with shifting response set) and visual planning skills were examined with a group of 60 children and adolescents with learning disabilities. The sample consisted of 44 boys and 16 girls with an age range of 9 to 15. Scores from the Trail Making Test and the Wisconsin Card Sorting Test were cluster-analyzed and subgroups were formulated. The results of the cluster analysis indicated a two-group solution to be most appropriate. One subtype was clearly dysfunctional on the classifying variables, while the other subgroup approached average levels. The two subtypes were compared on measures of intellectual functions, academic skills, auditory memory, visual memory, visual-motor integration, motor speed, and tactile integration. Significance was found on several different tests. The results are discussed in terms of potential cortical dysfunction evidenced by the subgroups.

The effects of cognitive and metacognitive strategy instruction on the mathematical problem solving of middle school students with learning disabilities.
This study investigated the effects of cognitive and metacognitive strategy instruction on the mathematical problem solving of six middle school students with learning disabilities. Conditions of the multiple baseline, across-subjects design included baseline, two levels of treatment, setting and temporal generalization, and retraining. For Treatment 1, subjects received either cognitive or metacognitive strategy instruction. Treatment 2 consisted of instruction in the complementary component of the instructional program so that all subjects eventually received both cognitive and metacognitive strategy instruction. This design allowed a componential analysis of the content as well as sequence of instruction. Generally, subjects improved their mathematical problem solving as measured by performance on one-, two-, and three-step word problems. Discussion focused on effectiveness of treatment, acquisition and application of strategic knowledge, error pattern analysis, and the need to tailor instruction to the learner's individual characteristics.

Fostering critical thinking skills in students with learning disabilities: an instructional program.
An instructional unit was developed to enhance the critical thinking skills of middle school and high school students with learning disabilities by teaching them the principles of scientific reasoning. Student-teacher dialogues were used to engage the students in an active process of critical inquiry. Students analyzed everyday information presented in brief magazine articles and advertisements by applying the principles of the scientific method. The students made statistically significant improvements in their ability to (a) identify the principal claim made in an article or advertisement, (b) graph the relevant data, and (c) evaluate the claims made in the article and explain their support or rejection of the claims based on data. After the instructional unit, the overall performance of the special education students exceeded that of a control group composed of regular education students who had not received instruction in critical thinking.

The oral syntactic proficiency of learning disabled students: a spontaneous story sampling analysis.
A comprehensive analysis of syntactic complexity was performed on spontaneously generated oral stories obtained from 93 learning disabled (LD) and normally achieving (NA) students, 14 to 16 each at 8:0-9:11 (years:months), 10:0-11:11, and 12:0-13:11 age levels. Syntactic complexity was measured using a structural constituent analysis and a T-unit analysis. In direct contrast to the extant LD literature, the results revealed almost identical rates of correct usage and extremely similar patterns of usage between the LD and NA subjects on all measures. Post-hoc analyses indicated that three syntactic structures were used by a significantly greater percentage of NA subjects than LD students. The significance of these findings is discussed with respect to: (a) previous and current characterizations of syntactic abilities of LD students; and (b) the importance of differentiating between statistical and clinical significance for the meaningful interpretation of research data.

Evaluation of behavioral group counseling for parents of learning-disabled children.
The present study evaluated the effectiveness of a behavioral group counseling program for parent members of the Association for Children with Learning Disabilities. Twenty-two mothers were assigned to two treatment groups (N = 5 and N = 6) and a control group (N = 11). Treatment-group mothers received a series of eight weekly 1 1/2-hour sessions in which they were taught basic principles and procedures of behavior modification which they could apply to specific child-rearing problems. Multiple-success criteria (maternal reports, direct observation, frequency counts, and attitudinal measures) were employed to provide a broad-based measurement of outcome. Results indicated that treatment ratings of childrens' conduct and disruption and parental postbehavioral observations of mother-child interactions showed improvement for the behavioral-counseling groups while control-group ratings and behavior observations remained the same. All treatment-group changes were maintained at 3-month follow-up. Consistency of treatment-group data across measures and over time suggests the effectiveness of this approach as a training method. Implications for future research were discussed.

Differences in semantic event-related potentials in learning-disabled, normal, and gifted children.
Cortical event-related potentials (ERP) were recorded over FZ, CZ, and PZ scalp sites in 15 learning-disabled (LD), 14 gifted (G), and 13 normal control (N) children of ages 8-12. The common stimulus consisted of nouns presented 80 percent of the time; the target stimulus of animal names presented 20 per cent of the time. ERPs were averaged over subjects from 180 msec pre-stimulus to 900 msec post-stimulus. Principal components analysis was used to determine if there were amplitude differences at different post-stimulus latencies as a function of condition. Differences in ERP's between groups (LD, gifted, and controls), scalp locations, and common versus target stimuli were analyzed by ANOVAs. P3, Late, P2, and N1 components represented by four factors were identified. Significant differences between G and LD and the N and LD groups were found target stimulus at all central locations for the P3 component. Differences were found centrally between G and LD, G and N, and N and LD groups for the P2 component centrally. Other differences were found for the N1 and late components. These differences could be interpreted as a deficit in either attentional mechanisms or information processing for the LD group.
