Language-Based Learning Disability Dictionary

LBLD Terms Defined and Demystified

group of students at Gow
Many parents call our Admissions Office in a panic, they just received testing results and are at a loss of what to do next. Often time’s reports can be up to 20 pages long with terms that are completely foreign to most. Below is a glossary of words and phrases and their definitions. We hope you find this information useful.



Anxiety disorders

"Disorders that share features of excessive fear and anxiety and related behavioral disturbances."1

Attention Deficit Hyperactivity Disorder (ADHD)

“A persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development.”2

  • Inattention manifests behaviorally in ADHD as wandering off task, lacking persistence, having difficulty sustaining focus, and being disorganized and is not due to defiance or lack of comprehension.
  • Hyperactivity refers to excessive motor activity when it is not appropriate, or excessive fidgeting, tapping, or talkativeness.
  • Impulsivity refers to hasty actions that occur in the moment without forethought and that have high potential for harm to the individual.3

Central Auditory Processing Disorder (CAPD)

"Refers to the efficiency and effectiveness by which the central nervous system (CNS) utilizes auditory information."4

Decoding

Using “visual, syntactic, or semantic cues to make meaning from words and sentences.” 5

Dyslexia

"Dyslexia is a brain-based type of learning disability that specifically impairs a person's ability to read. These individuals typically read at levels significantly lower than expected despite having normal intelligence. Although the disorder varies from person to person, common characteristics among people with dyslexia are difficulty with phonological processing (the manipulation of sounds), spelling, and/or rapid visual-verbal responding...Dyslexia can be inherited in some families, and recent studies have identified a number of genes that may predispose an individual to developing dyslexia."6

Dyscalculia

Dyscalculia is a learning disorder that results in “difficulty acquiring basic arithmetic skills that is not explained by low intelligence or inadequate schooling 7 People with dyscalculia have difficulties “processing numerical information, learning arithmetic facts, and performing accurate or fluent calculations.8

Read more details about dyscalculia, including symptoms and strategies to help students who have dyscalculia.

Dysgraphia

“Dysgraphia is a neurological disorder characterized by writing disabilities. Specifically, the disorder causes a person's writing to be distorted or incorrect. In children, the disorder generally emerges when they are first introduced to writing. They make inappropriately sized and spaced letters or write wrong or misspelled words, despite thorough instruction. Children with the disorder may have other learning disabilities; however, they usually have no social or other academic problems. In addition to poor handwriting, dysgraphia is characterized by wrong or odd spelling, and production of words that are not correct (i.e., using "boy" for "child").9

Executive function

“A set of processes that all have to do with managing oneself and one's resources in order to achieve a goal. It is an umbrella term for the neurologically-based skills involving mental control and self-regulation.”10 These processes include (but are not limited to): initiating tasks, planning, organizing materials, and self-monitoring.

Fluid reasoning

"The capacity to think logically and solve problems in novel situations, independent of acquired knowledge. It is an essential component of cognitive development, as this capacity serves as a scaffold for children, in helping them acquire other abilities.”11

Impairment of Written Expression

Impairment of written expression is a learning difficulty that results in difficulty with “spelling accuracy, grammar and punctuation accuracy, and clarity or organization of written expression.”12

Kinesthetic-tactile learning

A style of learning that requires manipulating or touching material or movement of the body to learn. Kinesthetic techniques are used in combination with visual and/or auditory study techniques, producing multi-sensory learning.13

Language-Based Learning Disabilities (LBLDs)

LBLDs cause “problems with age-appropriate reading, spelling, and/or writing. Most people diagnosed with learning disabilities have average to superior intelligence.”14 People with LBLDs can also struggle with speaking and listening. LBLDs fall under the broader umbrella of Specific Learning Disability (SLD).

Language Disorders (formerly Mixed Receptive-Expressive Language Disorder or Expressive Language Disorder)

There are two categories of language disorders: mixed receptive-expressive and expressive. People with a mixed receptive-expressive language disorder have difficulty understanding the meaning of what other people are saying, which affects their oral expression as well. An expressive language disorder results in difficulty conveying one’s thoughts, ideas, and feelings verbally, although they comprehend the spoken language.

Phonemic awareness

The ability to notice, think about, and work with the individual sounds in words.”15

Phonological awareness

“A skill that includes identifying and manipulating units of oral language, such as words, syllables, and onsets and rimes.”16

Processing speed

The pace at which one takes in information (either visually or auditorily), makes sense of it, and begins to respond.17

Reading comprehension

“The understanding and interpretation of what is read. To be able to accurately understand written material, children need to be able to (1) decode what they read; (2) make connections between what they read and what they already know; and (3) think deeply about what they have read.”18

Reading fluency

“The ability to read a text accurately, quickly, and with expression. Fluency is important because it provides a bridge between word recognition and comprehension. When fluent readers read silently, they recognize words automatically. They group words quickly to help them gain meaning from what they read. Fluent readers read aloud effortlessly and with expression. Their reading sounds natural, as if they are speaking. Readers who have not yet developed fluency read slowly, word by word.”19

Social (Pragmatic) Communication Disorder (SCD)

An SCD "is characterized by a persistent difficulty with verbal and nonverbal communication that cannot be explained by low cognitive ability. Symptoms include difficulty in the acquisition and use of spoken and written language as well as problems with inappropriate responses in conversation. The disorder limits effective communication, social relationships, academic achievement, or occupational performance. Symptoms must be present in early childhood even if they are not recognized until later when speech, language, or communication demands exceed abilities.” 20

Specific Learning Disability (SLD)

An SLD is a “disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written, in which the disorder may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations, including conditions such as perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia.”21

Visual-spatial ability

“The capacity to understand and remember the spatial relations among objects…Visual-spatial skills are of great importance for success in solving many tasks in everyday life. For instance, using a map to guide you through an unfamiliar city, merging into high-speed traffic, and orienting yourself in your environment.”22

Word attack

Skills used to decode, pronounce, and understand unfamiliar words.

Working memory

A system for temporarily storing and managing the information required to carry out complex cognitive tasks such as learning, reasoning, and comprehension.23
