ASL phonology in handshapes P or K and T
The handshapes P or K (same handshape but different wrist orientation) and T seem to be phonologically related.
Emerging ASL handshape P or K in ASL
The handshape "K" or "P" (both same handshape but different orientation) began to emerge as seen in park. The movement in this production also developed to a more circular.
In parallel, the handshape in the production for video had transitioned from a long-time handshape "A" to the emerging correct handshape "V". The movement remained the same. Juli tapped instead of making a circular movement.
A week later (age 2;5,3), the movement when producing video began to form a circular movement. Likewise for the ASL sign park.
The emergence of ASL handshape T
Another phonological emergence at age 2;8.1 was the ASL handshape "T". The toddler Juli now could produced a fingerspelled loan #TV clearly. She would ask ix-me want watch #TV and laughed.
Shortly, she was able to form the handshape F. I introduced her to the ASL words that contain the handshape F: cat, fox, and sentence. One day, I caught her practicing this handshape and signed all these three words.
Although, the handshape F hadn't been stable for the next months as Juli still formed the "W" handshape in replacement of F.
Interesting, both the handshapes T and F are somehow phonologically related that both require the skillful control of the thumb and the index finger.
Eventually, Juli signed toilet with the handshape T correctly. Sometimes, she would sign this with the handshape A and I'd remind her.
More phonological development in ASL
Last week the toddler Juli responded to high-fives and waving ILY with the handshape W. Forming the handshape ILY is a long phonological process.
Juli produced her three-year-old friend Hayden's signed name perfectly -- two-handed "X" handshape, moving alternativley in front of the face.
Juli wanted to select a specific cartoon ("Super Pets") on the screen but I haven't introduced her the ASL word/sign hamster as shown in the selection list. Once I introduced this signed word for the first time, Juli produced it correctly (with the correct "U" or "H" handshape).
Juli used the ASL word want more often in her simple sentences: want bubble, want climb, want apple, etc.
Some of the following random words and phrases that Juli used this week: eat mother milk, want drink, car, man cl-get-on + cl-ride, school bus, father sick (handshape W for sick), horse ride-on (sitting on the crib fence), Hayden (perfectly producing her friend's signed name), some more shown in the video above, and other ASL words mentioned in the past months.
