Gosh, so many interesting and relevant pointsraised by all when I was off climbing a mountain this afternoon.
Where to begin?
9-5, no behaviourist (as in someone with an MSC or PhD or board certified status) would argue against the fact that we are operating under ontogenic and phylogeni stimuli (that is some facotrs in our behavious arise from contingencies with the environment and some are directly attributable to something in us as part of an evolutionary process.
The issue is, which is which and what can we change? BAs have mroe in common with s/lts than they think as any s/lt will tell you that the environment in which a language impaired person has to change if the person is going to. That is exactly what a BA does-tinkers with contingencies and schedules of reinforcement.
The points you raise about odd inflexible 'programmes' for language facilitation in kids with reasonable language are good. I work very closely with the BA who works with my child. I tend to be the one who tells her what it is she needs to work on (making ample use of trusty old work horses like the TROG and TALC) and she tends to devse the data collection techniques and rearrange the contingencies to make it all possible. I like to think that we are a dream team.
Similarly I can be very
about some of the early work BAs do on eliciting sounds.For a start they have no clue as to the physiological aspects of phnology and how the holy trinity of voice/place and manner work. An s/lt whose workshop I attended on s/lt/ABA for kids with ASD (bloody brilliant) in the Startes pointing out that in VP-MAPP the sound orthographically notated as 'ng' is worked on as two differnet sounds, 'n' and 'g' wherease any s/lt with a rudimentary knowledge of Phonology knows it is one phoneme!
So I see well meaning BAs picking up randowm phonemes from all over the place to work on with no understanding of how they fall into natural clusters.
AT that whole vagueness abouit your child learning idioms is a good example of how unacceptable and vague everything has become and sadder still ,the parties involved have no idea how to address it.
Getting that right is so easy it is laughable. With a system like SAFMEDS (PT) you could spend no more than 10 mins. a day and churn throguh literally dozens of idioms in a way that is fun, fast paced and shows very clearly where a child started and where they got to and how long it took.
Mind you, as 9-5 says, one has to be careful re idioms. Working on something like 'tickled pink' would be daft (as she says, what kids says that anyway??) but 'pulling your leg' would be good.
S/lts can get very precious and demand to be taken seriously as a profession, My argument is this;how seriously can you really excpect peopel to take you if you can not measure how effective your intervention has been and prove that, as a result of your being around, the child has acquired x, y and z. these being entities he didn't have before you came on the scene.
I am mortified at the quality of much of my work before I learnt about data collection and analysis/I always worked hard and tried my best but streuth!!!
The less said, the better.
