Question

1. based on experiments done with animals, which of the following statements about environmental influences on brain development is correct? select one: a. negative experiences have been shown to have an adverse impact on development only when the infant is born with a genetic vulnerability. b. early experiences can affect cognitive and social functioning but cannot bring about actual physical changes. c. positive experiences or an enriched environment can spur brain development. d. negative experiences have been shown to have little or no effect on brain development. 19. typically, the first sense to develop in the infants is the sense of select one: a. hearing. b. smell. c. touch. d. sight. 20. jennas doctor recommends that she provide her newborn son with more sensory stimulation focusing on touch. which of the following techniques should jenna use? select one: a. rub the infants back. b. show the infant complex pictures. c. turn the lights on and off. d. test his locomotor reflexes.

Explanation:

1. Positive experiences or an enriched environment can promote brain development in animals and humans. Negative experiences can have an impact even without genetic vulnerability, and early - experiences can lead to physical brain changes. So, for the first question, positive experiences can spur brain development.
2. The sense of touch is one of the first senses to develop in infants.
3. To provide sensory stimulation focusing on touch, rubbing the infant's back is a touch - based technique. Showing pictures is for vision, turning lights on and off is also related to vision, and testing locomotor reflexes is not a touch - focused sensory stimulation.

Answer:

1. C. Positive experiences or an enriched environment can spur brain development.
2. C. touch
3. A. Rub the infant's back
