Question 1

Negative influences,such as abuse,neglect,or poor nutrition,have no effect on motor development.

Accepted Answer

Negative influences, such as abuse, neglect, or poor nutrition, can have a significant impact on motor development. Children who experience abuse or neglect may have delays in their motor development due to lack of proper stimulation and opportunities to practice motor skills. Poor nutrition can also contribute to motor delays or impairments. It is important for children to have a healthy and nurturing environment in order to develop their motor skills properly.

Question 2

Polygenic traits involve the combined impact of multiple genes and/or are influenced by the environment.

Accepted Answer

Polygenic traits are influenced by the combined effect of multiple genes and may also be affected by environmental factors.

Question 3

The belief that development is biologically programmed to happen sequentially is known as maturation.

Accepted Answer

Maturation is the belief that development is biologically programmed to happen sequentially.

Question 4

Daewon's longitudinal work indicated that individuals had significantly lower fears around terrorism in the 1990s than they did in the 2002.This is an example of a cohort effect.

Accepted Answer

A cohort effect is when a group of people who share a similar experience or time period have a unique response or outcome in comparison to other groups. In this case, Daewon's longitudinal study suggests that people who lived through the 1990s had a different response to the fear of terrorism compared to those who lived through 2002, indicating a cohort effect.

Question 5

Cognitive development refers to how thinking develops with age.

Accepted Answer

Cognitive development refers to the growth and maturation of mental processes and abilities, including perception, memory, language, problem-solving, and decision-making, which change and improve throughout a person's lifespan.

Question 6

The age of survivability refers to when a newborn baby can survive on its own.

Accepted Answer

The age of survivability refers to the age at which a newborn baby can survive outside the mother's womb with the help of medical intervention and technology, such as incubators, ventilators, and other life support systems. It varies depending on the baby's gestational age, overall health, and access to medical care. No newborn baby can survive on its own immediately after birth.

Question 7

Piaget's theory states that children's cognitive abilities differ according to age.

Accepted Answer

Piaget's theory of cognitive development posits that children's cognitive abilities undergo qualitatively different stages according to age.

Question 8

Understand the key debates underlying research and theory in child development.

Accepted Answer

The answer of Understand the key debates underlying research and...

Question 9

Johnston has two alleles for blue eyes.Johnston is heterozygous for blue eyes.

Accepted Answer

If Johnston has two alleles for blue eyes, he would be homozygous for blue eyes, not heterozygous. Heterozygous means having two different alleles for a trait.

Question 10

The experiment Ainsworth developed to study attachment is called the Strange Situation.

Accepted Answer

Ainsworth's experiment to study attachment is called the Strange Situation.

Question 11

Vision is the most highly developed sense immediately following birth.

Accepted Answer

Actually, vision is the least developed sense immediately following birth. Babies only have about 5% of adult visual acuity at birth and it develops gradually over the first few months of life.

Question 12

Piaget claimed that all children develop in the same way and there is no variation in the timing of developmental milestones.

Accepted Answer

Piaget's theory acknowledged individual differences and variations in the timing and pace of cognitive development among children. While he proposed a general sequence of stages, he recognized that not all children progress through them at the same rate or in the same way.

Question 13

A sensitive period is a period when children are particularly receptive to environmental influence.

Accepted Answer

During sensitive periods, children have an increased sensitivity to stimuli in their environment and are more receptive to learning specific skills or behaviors. These periods are crucial for development and can have a lasting impact on a child's abilities and personality.

Question 17

As we grow older,80% of our early synaptic connections are lost.

Accepted Answer

While synaptic pruning does occur, where the brain eliminates excess synapses, the figure of 80% loss is an overstatement. Synaptic pruning refines neural connections based on experiences, but the extent of loss is not as high as 80%.

Question 18

Continuous development involves clear qualitative differences in thinking or behaviour.

Accepted Answer

Continuous development is characterized by gradual, incremental changes rather than clear, qualitative differences.
