Causes of LD

Question 1

Environmental model

Answer 1

• holds poor learning environment, unstable families, disadvantaged environments and faulty school instruction responsible for LD. (Ple, Uf, De, Fsi / learning, family, env, school instruction )
• This model is important because improvement of LD according to this model lies in the change in environment: proper schooling and removal of unhealthy influences. (Ps, Rui / Schooling, unhealthy influences )

Question 2

Brain Damage model

Answer 2

suggests that 20 percent of students with LD have sustained brain damage or neurological damage. The term minimal brain dysfunction is often used because of the lack of proper neurological causes. It is assumed that the child may have experienced injury to central nervous system during birth or before birth.

(Brain/neurological, Minimal Brain Dysfunction, Central Nervous System - birth or before)

Question 3

Organic and Biological Model

Answer 3

• Organic: suggests that chemicals used in food coloring and flavoring substances, imbalances in neurotransmitters and vitamin deficiency (especially B complex) could cause LD. ( Fc, Fs, In, Vd / Food, Flavor, Neurotransmitters, Vitamins)
• Biological : Developmental or maturation unpreparedness for certain tasks is also believed to underlie some LDs.

Question 4

Genetic Model

Answer 4

suggests an inherited genetic influence may be cause reading and language problems. More research is required to discover the relationship between genetic inheritance and specific LD.

In summary:
The causes of LD may be embedded in the child as well as in the environment and may be complicated by organic, genetic or biological anomalies.
