The model asserts that infants first come into this world with
certain basic adaptive processes (BAPs) which permit them to adapt,
with greater or lesser effectiveness and efficiency, to their
environment (See Stage 1 of Figure 1). Examples of these basic
processes are: hearing and seeing, which are BAPs for the reception
of sound and light; motor movement, which is the BAP for orienting
to and manipulating the environment; and the cognitive BAPs, which
include the basis for a memory system and rudimentary ways of
processing (ie., storing, retrieving, and using) information.
Definitions Used in the Model
- Basic Adaptive Processes (BAPs): Sensory, Perceptual, Motor, and Cognitive
capacities operating at birth by means of which the infant adapts to the
- Hearing: BAP for reception of sound.
- Seeing: BAP for reception of light.
- Motor Movement: BAP for orienting to and manipulating the environment.
- Cognitive: BAP for storing, retrieving, and using information.
- Precursors to the receptive processes for languaging.
- Listening: Selecting and attending to excitation in the auditory modality.
- Looking: Selecting and attending to excitation in the visual modality.
- Precursors to the expressive processes for languaging.
- Uttering: Production of vocal sounds; i.e., sounds produced using the
larynx and oral cavities.
- Marking: Manual motor movements producing marks (lines, scribbles) on
- Language (noun): System of a) conventionalized signs, and b) rules for selecting
and sequencing these signs.
- Language (verb-to language, languaging): Representation
of conceptualizations by properly ordered sequences of signs; or the
inverse process of understanding the conceptualizations underlying
the sequences of signs
produced by others.
- Gracy Processes
- Auding: Listening to speech in order to language.
- Speaking: Uttering in order to language.
- Literacy Processes
- Reading: Looking at script in order to language.
- Writing: Marking in order to language.
