Symbol Systems & Visual Supports Flashcards

The LAMP (Language Acquisition through Motor Planning) approach to AAC is based on which theoretical foundation?

Answer: Motor learning theory, emphasizing consistent motor patterns for automatic, fluent symbol retrieval

LAMP is grounded in motor learning theory, which holds that consistent motor movements for each word build automatic, unconscious retrieval, freeing cognitive resources for language.

Which of the following BEST explains why fringe vocabulary is important to include alongside core vocabulary in an AAC system?

Answer: Fringe vocabulary provides person-specific and topic-specific nouns that make messages meaningful and individualized

Fringe vocabulary provides specific nouns (people's names, favorite items, unique topics) that personalize messages and fill the gaps that core vocabulary alone cannot cover.

A practitioner is evaluating symbol placement on a VOCA for a child with hemiplegic cerebral palsy affecting the right side. Which consideration is MOST critical?

Answer: Positioning frequently used symbols within the optimal motor access range of the child's functional left hand

Motor access patterns must be considered in display design; for a child with right-side hemiplegia, core symbols should be placed within the reach envelope of the functional left hand.

What does 'symbol transparency' mean in the context of AAC assessment?

Answer: The degree to which a symbol's meaning can be guessed by naive viewers without prior instruction

Symbol transparency refers to how easily unfamiliar viewers can identify a symbol's intended meaning without prior teaching, which affects learnability and partner interpretation.

Which organizational strategy places symbols based on their frequency of use and motor efficiency rather than semantic categories?

Answer: Motor-based organization (e.g., frequency-of-use placement)

Motor-based organization places the most frequently used symbols in the easiest-to-access motor positions, reducing fatigue and improving communication rate.

A client uses a tangible symbol system. Which population is MOST likely to benefit from tangible symbols?

Answer: Individuals with significant visual and cognitive impairments who have not yet developed symbolic understanding

Tangible symbols (objects or textured representations) are most appropriate for individuals with dual sensory impairments or those at pre-symbolic communication levels who rely on tactile and object-based information.

When introducing a new symbol to an AAC learner, which teaching sequence is MOST aligned with systematic instruction principles?

Answer: Use errorless learning to establish the symbol, then transfer to natural contexts using least-to-most prompting

Systematic instruction begins with errorless learning to establish correct symbol-referent associations, then uses prompt hierarchies to promote generalization in natural communication contexts.
