Some expressive language skills include putting words together into sentences, being able to label objects in an environment and describing events and actions. Receptive Language Delay
Children that are diagnosed with receptive language delay have difficulties understanding language. They may have trouble with receptive language skills such as identifying vocabulary and basic concepts, understanding gestures, following directions and answering questions. The number of language skills that children have difficulties with can differ greatly, with some having trouble with only a single skill and others having trouble with multiple. Expressive Language Delay
A child diagnosed with expressive language delay (ELD) has trouble with language usage in some way. As this diagnosis is very broad, each child diagnosed with ELD can be very different in terms of the language skills they have problems with. Some may have difficulty with using the correct words and vocabulary, some have trouble forming sentences and others are unable to sequence information together coherently. Expressive language symptoms come in many forms and each one is treated with different methods. Presentation and Diagnosis
A language delay is most commonly identified around 18 months of age with an enhanced well-baby visit. It presents itself in many forms and can be comorbid or develop as a result of other developmental delays. It is important to remember that language delays act and develop differently individually. Language delay is different than individual variation in language development, and is defined by children falling behind on the timeline for recognized milestones.
Other potential adaptations to improve visual function in higher environmental complexity may include strategies like clearing away excess clutter from a work spaces, or providing a plain background to view objects against, reducing noise levels, or other methods of monitoring and adapting for environmental complexity. One eye may perform significantly worse than the other, and depth perception can be very limited (although not necessarily zero). The field of view may be severely limited. The best vision might be in the centre (like tunnel vision) but more often it is at some other point, and it is difficult to tell what the person is really looking at. Note that if the person also has a common ocular visual impairment such as nystagmus then this can also affect which part(s) of the visual field are best. (Sometimes there exists a certain gaze direction which minimises the nystagmus, called a "null point.") Even though the field of view may be very narrow indeed, it is often possible for the person to detect and track movement. Movement is handled by the V5 part of the visual cortex, which may have escaped the damage. Sometimes a moving object can be seen better than a stationary one; at other times the person can sense movement but cannot identify what is moving. (This can be annoying if the movement is prolonged, and to escape the annoyance the person may have to either gaze right at the movement or else obscure it.)
