Responding to Students with Nonverbal Learning Disabilities Cathy F. Telzrow Aimée M. Bonar Would you know whether a student of yours has the syndrome of nonverbal learning disability (NLD)? If you were included on a planning committee for this student’s individualized education program (IEP), what would you recommend or plan? Recognizing NLD and providing responsive educational programming for affected students are critical if we are to ameliorate the poten- tially devastating course of this disorder (Fletcher, 1989; see box, “What Is NLD?”). This article provides an overview of the NLD syndrome to assist educators in identifying this frequently overlooked condition and to describe educational strategies, or interventions, for the special challenges experienced by students with this disability. What Is NLD? TEACHING Exceptional Children, Vol. 34, No. 6, pp. 8-13. Copyright 2002 CEC. Over the past 15 years, researchers and clinicians have described a profile of characteristics that comprise the syndrome of nonverbal learning disability (NLD). Although initially identified in 1975 as a neurologically based disorder with specific clinical and educational markers (Myklebust, 1975), many educators are unfamiliar with NLD for the following reasons: • Few textbooks used in teacher preparation programs mention this disorder, resulting in limited exposure to its characteristics and implications for student adjustment. • Much of the literature concerning this disorder has appeared in medical and psychological publications rather than in sources typically accessed by educators. • The NLD profile may result from a variety of neurological and developmental conditions, including moderate to severe head injuries, untreated hydrocephalus, and Asperger syndrome (Rourke, 1988), and these diagnoses may obscure the symptom complex that is characteristic of NLD. • The disorder is poorly understood because the pervasive cognitive and interpersonal features associated with NLD are quite disparate from those observed in the majority of students with learning disabilities, whose difficulties tend to be restricted to the areas of reading and spelling (Palombo & Berenberg, 1999; Rourke & Tsatsanis, 2000). 8 ■ COUNCIL FOR EXCEPTIONAL CHILDREN An NLD Profile Distinctive patterns of strengths and weaknesses in neuropsychological, academic, and social-emotional functioning characterize people with NLD (GrossTsur, Shalev, Manor, & Amir, 1995; Rourke, 1988, 1989; Rourke & Tsatsanis, 2000). One of the hallmark characteristics is stronger verbal than nonverbal cognitive abilities, as evidenced by higher Verbal than Performance IQ scores. This pattern of cognitive strengths and weaknesses extends to attention and memory skills, and students with NLD perform better on such tasks when information is presented verbally rather than through visual or tactile modes (Fisher & DeLuca, 1997; Landau, Gross-Tsur, Auerbach, Van der Meere, & Shalev, 1999; see Table 1). Students with NLD also demonstrate weak psychomotor and perceptual motor skills that persist across time (Rourke, 1988). They tend to be physically awkward and have particular difficulty acquiring gross motor skills that are necessary for age-appropriate self-care and play tasks, such as dressing, skipping, jumping rope, or riding a bicycle (Casey & Strang, 1994). In addition, students with NLD perform significantly below average on standardized motor and visual motor tests (Gross-Tsur et al., 1995) Table 1. Characteristics and Indicators of the NLD Syndrome Primary Characteristics of NLD Possible Indicators of the NLD Syndrome Stronger verbal than perceptual cognitive skills Higher Verbal IQ than Performance IQ scores Stronger on verbal than visual attention and memory tasks Weak psychomotor and perceptual motor skills Physically awkward: slow to skip, ride bike, jump rope Difficulty with tracing, cutting, and coloring Sloppy handwriting Deficiency in arithmetic Better reading and spelling than arithmetic performance Problems with number alignment and directionality Confusion of mathematical symbols and problem-solving sequences Difficulty with novel and complex tasks Rote memory performance superior to tasks requiring integration and synthesis Reliance on automatic verbal responses in novel situations Poor problem-solving skills May be inflexible, unable to consider alternative actions Difficulty with changes in routine Social and interpersonal deficits Misinterprets social cues: may be too impulsive, too familiar Tendency to be teased or bullied; prone to social withdrawal Pedantic, “little professor” style of communication Unusual prosody, such as mechanical, “robot-like” speech Difficulty understanding jokes or sarcasm Limited self-awareness; unrealistic in vocational choices Psychosocial adjustment problems Evidence of inattention and hyperactivity during preschool and primary grades Higher prevalence of anxiety and depression during adolescence Increased risk of suicide during adolescence and young adulthood Note: The NLD (nonverbal learning disability) syndrome may be indicated when there is a pattern of characteristics and indicators present. and struggle with skills such as tracing, cutting, coloring, and handwriting. Their performance in these areas contrasts sharply with their early reading and spelling skills, which are frequently above average. This pattern of uneven skill development in kindergarten and first grade signals a characteristic profile of academic strengths and weaknesses in NLD. Students with this disorder tend to excel on reading/decoding and spelling tasks, but struggle with mechanical arithmetic, as indicated by difficulty solving arithmetic problems and confusion of mathematical symbols and procedures (GrossTsur et al., 1995; Rourke, 1988). In addition, people with NLD have difficulty on tasks that are novel and complex, such as higher-order academic skills and many social situations. Consequently, they commonly have adequate to good mastery of early rote skills, followed by difficulty with making inferences and synthesizing and integrating content in the middle grades and beyond. Furthermore, these cognitive deficits appear to be exacerbated in unfamiliar settings and situations. The difficulties that students with NLD demonstrate in responding to novel, unpredictable tasks affect their ability to change cognitive set and consider alternative possibilities, which results in impaired problem-solving skills. As a result, these individuals do not respond well to changes in well-rehearsed routines and may function inappropriately during school transitions or unstructured recreational activities. Students with NLD demonstrate an unusual pattern of social and interpersonal weaknesses, many of which are directly linked to underlying cognitive and neuropsychological deficits (Voeller, 1995). Such students tend to have poor social judgment, which may be evidenced by impulsive behavior, inappropriate affect, or the tendency to invade others’ personal space. Although the name of this disorder—nonverbal learning disability—suggests that verbal skills are intact in students with NLD, in fact, subtle language deficits are present. Specifically, social pragmatic skills are typically impaired, meaning that students with NLD do not use communication effectively within a social context. Their speech One of the hallmark characteristics of students with NLD is stronger verbal than nonverbal cognitive abilities. TEACHING EXCEPTIONAL CHILDREN ■ JULY/AUGUST 2002 ■ 9 may have unusual prosody or rhythm, resulting in poorly inflected, “robot-like” speech. In addition, their conversational skills are often pedantic, and they may misperceive nonverbal nuances in communication that are necessary for understanding jokes or sarcasm. As a result of such social and interpersonal deficits, students with NLD may be victimized, teased, or bullied by other children (Casey & Strang, 1994). They may gravitate toward adults, who are likely to engage in verbal rather than physical activities and who may have more tolerance for their “little professor” communication style. Over time, students with NLD frequently experience social withdrawal and isolation. Finally, distinctive psychosocial adjustment problems have been associated with the NLD syndrome, and these may change over time. Young children with NLD (i.e., preschool and primary children) frequently have inattentive, hyperactive, and impulsive behavior patterns, which may lead to a diagnosis of attention deficit/hyperactivity disorder (ADHD; Gross-Tsur et al., 1995; Voeller, 1995). As students with NLD become older, such behaviors may be replaced by a pattern of internalizing adjustment problems, characterized by pervasive anxiety and a high incidence of depression (Cleaver & Whitman, 1998; Palombo & Berenberg, 1999). Of particular concern is evidence that students with NLD may be at increased risk for suicide during their adolescent and young adult years (Bigler, 1989; Rourke, Young, & Leenaars, 1989). Interventions for NLD Many of the characteristics of NLD— weak psychomotor and perceptual motor skills; arithmetic disabilities; weaknesses in synthesizing and inte- Distinctive psychosocial adjustment problems have been associated with the NLD syndrome, and these may change over time. 10 ■ COUNCIL FOR EXCEPTIONAL CHILDREN grating information; poor problem-solving skills; social and interpersonal skill deficits; and internalizing adjustment problems, such as anxiety and depression—have significant educational implications. Figure 1 shows many interventions that educators, parents, and clinicians might use with students with this disability. We derived this list of recommended strategies and approaches from the clinical and educational literature. We hope that they may serve as guides as professionals—and parents—design appropriate services for students with this challenging disorder. We have shown three types of intervention for each skill area listed: remedial, compensatory, and instructional or therapeutic. • Remedial interventions are designed to exercise deficient skills directly. For example, Rourke (1988) indicated Intensive training and practice in handwriting for students with NLD could result in marked improvement over time. that intensive training and practice in handwriting for students with NLD could result in marked improvement over time. • Compensatory approaches employ assistive technology or other techniques to assist students with NLD in circumventing areas of deficit in their achievement of academic objectives. Concerns about sloppy handwriting, for example, are minimized when students can use a word processor; and a calculator can help students keep pace with their classmates despite weaknesses in mechanical arithmetic. • Instructional or therapeutic interventions use specialized methods to teach the student foundational skills or strategies to enhance performance in deficient areas. Examples include problem-solving instruction, socialskills training to develop personal and As students with NLD become older, they may have pervasive anxiety and depression—and they may be at increased risk for suicide during their adolescent and young adult years. interpersonal skills, and cognitive behavioral interventions to address depressive symptoms. You should select an approach according to the individual student characteristics, including age (e.g., remedial interventions are more frequently found to be effective in younger than older children), the severity of deficits, the degree of functional impairment, and evidence of preserved abilities (Rourke, 1989). Final Thoughts The identification of the NLD syndrome is complicated by several factors, as follows: • Multiple etiologies may produce the characteristic profile of strengths and weaknesses. • The disorder may masquerade as one of its primary deficits, such as an arithmetic disability or depression. • There are age-related expressions of the disorder that change over time. Well-informed educators can help overcome these challenges to timely identification of students with this syndrome and may find effective approaches to enhance student performance.
