Language acquisition | Faster language acquisition through early emphasis on functional language.
By teaching language for obtaining reinforcers (i.e. mands), this approach encourages faster language acquisition; the child would learn that using language is valuable for obtaining their favorite items or activities. |
Language training is more limited.
Children are taught receptive (comprehension) and expressive language. |
||
Reinforcement & Motivation |
Ongoing emphasis on capturing motivation.
We recognize that a child’s desire for certain items or activities change over time. A simple example would be a child losing interest in obtaining cookies once they are full. Thus, constant monitoring is required to sustain child’s motivation for learning. |
Insensitive to changes in child’s motivation to obtain a particular reinforcer. | ||
