What are teratogens?

• Substances that cause birth defects or developmental problems in a fetus

• Genetic mutations inherited from parents

• Maternal illnesses that affect fetal development

• Environmental factors like air pollution and radiation

Which of the following is a characteristic of genetic mutations?

• They are always inherited from parents

• They can only affect physical development

• They can occur spontaneously or be inherited, leading to various disorders

• They are primarily caused by environmental toxins

How do hormones impact fetal development?

• They only regulate bodily functions, not brain development

• Imbalances can lead to atypical brain development, affecting behavior and cognitive abilities

• They are primarily responsible for genetic mutations

• They are external elements that can affect prenatal development

What is the primary purpose of infant reflexes?

• To help infants learn complex motor skills

• To indicate healthy neurological development and aid survival

• To allow infants to communicate their needs

• To help infants adapt to cultural factors

Are you enjoying the video lesson?

• Yes

• No

What is the primary difference between gross motor skills and fine motor skills?

• Gross motor skills involve smaller movements, and fine motor skills involve larger movements.

• Gross motor skills develop later than fine motor skills.

• Gross motor skills involve large movements, while fine motor skills involve small movements.

• Gross motor skills are learned in adolescence, and fine motor skills are learned in infancy.

What type of development does the visual cliff experiment study?

• Language acquisition

• Fine motor skills

• Depth perception

• Emotional attachment

What is the key distinction between a critical period and a sensitive period in development?

• Skills learned during a critical period are permanent, while those from a sensitive period are temporary.

• A critical period is a specific time when a skill must be acquired, whereas a sensitive period is when the brain is primed to learn a skill more easily.

• Critical periods apply only to physical development, while sensitive periods apply to cognitive development.

• Sensitive periods are longer in duration than critical periods.

Which of the following best describes primary sex characteristics?

• Traits indirectly related to reproduction, such as broader shoulders or less facial hair.

• Hormonal changes that occur during puberty.

• Traits directly related to the reproductive system and the ability to reproduce.

• Rapid increases in height and weight during adolescence.
