Hand targeting to teach offered arm for blood testing. The brush is the sensory target, as soon as she touches the brush I TAG and reinforce by stroking the offerd arm in position with the brush. Then I raise the criteria where Tink has put her arm over my hand to touch the target. The TAGpoint is Tinks elbow to my hand. I reinforce the same way as before in position. The next TAGpoint is me holding her arm again TAG this and reinforce in position by stroking hand with brush. Then I just build up the duration of me holding Tinks arm.
