...turned out to be a strong taster of the bitter stimuli phenylthiocarbamide (PTC) and propylthiouracil (PROP). The ability or inability to taste these stimuli is genetic. To taste very weak concentrations, as I did, indicates that the subject is probably homozygous, or has two dominant genes for bitter tasting. People who perceive PTC/PROP mildly are likely to be heterozygous, meaning that they have one dominant and one recessive gene. Non-tasters of these bitter stimuli have two recessive genes. It was interesting to notice how the tastes literally "felt" as they were being washed over the tongue. Salt and sweet...
...only requires a flashlight, a red ball, a bell, a rattle and a safety pin. Success depends on the skill of the examiner, who must guide the baby in and out of sleep, calm alertness and crying, while he watches the child's reaction to his simple stimuli. The baby will establish his own pattern of responses out of the infinite number of possibilities, and so give the examiner clues to personal characteristics. "With the scale, we can identify an active baby, a quiet baby, a cuddly baby, a normal baby." Tronick said...
...registered nurse in the maternity unit of a New York hospital, and when I talk to babies just out of the delivery room they respond to my voice and other sounds. They see and react to a soothing touch and consistently avoid painful or frightening stimuli. In the first week of life they are much more aware than most people realize...
...folksy sort of test, carried out with such implements as a pocket flash light, an orange rubber ball, a paper clip, some popcorn kernels. The exam starts when the baby is asleep, and it gauges the infant's reactions to a series of stimuli, including light in the eyes, the sound of rattling, a scratch on the foot: 20 reflexes and 26 behavioral responses in all. After 20 minutes or so, a Brazeltonized baby is wide awake and none too happy about all the testing...
Research with animals has shown that when stressful stimuli can be regulated, they are rendered
