Question

1a)Two groups of newborn babies were hooked up to a special pacifier that recorded their
sucking movements. One group of babies heard Swedish before birth, the other heard
English. All the babies were played a series of Swedish and English sounds. The babies who
had heard Swedish prenatally sucked more when they heard Swedish. The babies who had
heard English prenatally sucked more when they heard English. This pattern of results
suggests that:
i. Newborns remember aspects of the prenatal experience
ii. There is continuity in development from prenatal to postnatal life
iii. Babies are not able to discriminate languages until they are born
iv. i & ii
1b)The process of myelination results in an increase in white matter. Myelination happens
for all brain regions. Because of increases in myelination
i. At different times; neural signals can travel through the brain faster
ii. At different times; neurogenesis is improved
iii. At the same time; neurogenesis is improved
iv. At the same time; neural signals can travel through the brain faster
1c) Which of the following is an illustration of experience-dependent plasticity?
i. Rats raised in cages with toy have more dendritic spines and more synapses per neuron
than rats raised in cages without this stimulation
ii. The brain expects experiences that all humans have (such as visual and auditory input)
and uses them to shape the structure of the brain.
iii. Adults who became blind early in life were better able to discriminate musical pitch than
were those who became blind later in life.
iv. All of the above

Human development or developmental psychology is one of the most highly focused area of psychology which covers the scientific study of how pre natal as well as post natal development takes place, why development takes place in a certain way and what are the major factors that influence development.
