Final answer:
An infant with inhibited temperament as described by Kagan has a low heart rate, low cortisol levels, and low activity in the right frontal lobe of the brain.
Step-by-step explanation:
The statement is True. An infant with inhibited temperament as described by Kagan does indeed tend to have a low heart rate, low cortisol levels, and low activity in the right frontal lobe of the brain.
Kagan's theory of inhibited temperament suggests that some infants are born with a temperament that leads them to be more shy and withdrawn compared to others. These infants tend to exhibit physiological markers of inhibition, such as a lower resting heart rate, lower cortisol levels (which is a stress hormone), and reduced activity in the right frontal lobe of the brain.
Research has shown that these physiological characteristics are associated with a higher sensitivity to novelty and a greater likelihood of experiencing anxiety or fear in new situations. It is important to note that temperament is influenced by a combination of genetic and environmental factors.
