What is the difference between Identical and Fraternal twins?

• Identical twins - 50 per cent genetic match, Fraternal twins - approximately 25 per cent gene match, same amount as any set of brothers and sisters

• Fraternal twins - 100 per cent genetic match, Identical twins - approximately 50 per cent gene match, same amount as any set of brothers and sisters

• Fraternal twins - 50 per cent genetic match, Identical twins - approximately 25 per cent gene match, same amount as any set of brothers and sisters

• Identical twins - 100 per cent genetic match, Fraternal twins - approximately 50 per cent gene match, same amount as any set of brothers and sisters

How are adoption studies useful?

• Similarities between children and their adoptive parents would suggest neither environmental of inherited influence is greater

• Similarities between children and their adoptive parents would suggest environmental (Nurture) influence is greater

  Whereas similarities between adopted children and their biological parents would indicate inherited (Nature) influence is greater.

• Similarities between adopted children and their biological parents would indicate neither environmental or inherited is greater

• Similarities between children and their adoptive parents would suggest inherited (Nurture) influence is greater

  Whereas similarities between adopted children and their biological parents would indicate environmental (Nature) influence is greater.

Studies of Adopted children have provided considerable support for the view that:

• inheritance plays a significant role in an individual’s food preference

• inheritance plays a significant role in an individual’s care giver attachment

• inheritance plays a significant role in an individual’s Psycho-social development

• inheritance plays a significant role in an individual’s intelligence

Physical development is

• environmentally determined biological change

• genetically predetermined psycho-social development

• genetically predetermined biological change

• environmentally determined psycho-social development

Cognitive development is:

• Development of mental illnesses

• Development of our mental abilities (e.g Memories, Language, Problem solving, Perception)

• Development of our Psycho-social (e.g Relationships, Career)

• Development of our physical abilities abilities (e.g Strength, coordination, fitness)

What is a developmental Norm?

• Developmental norms indicate the set age that a certain behaviour or skill will be achieved.

• Developmental norms indicate the set age that a critical period occur.

• Developmental norms indicate the average age that a critical period occurs.

• Developmental norms indicate the average age that a certain behaviour or skill will be achieved.

What is one difference between critical and sensitive periods of development?

• Sensitive - Gradual e.g Visual development, Cognitive - Abrupt e.g Language development

• Sensitive - Gradual e.g Language development, Critical - Abrupt e.g Visual development

• There is no difference, they occur at the same time during infant development

• Critical - Gradual e.g Language development, Sensitive - Abrupt e.g Visual development

What is most commonly developed during sensitive periods of development?

• Nervous system development

• Internal organ development

• Brain cell connects (proliferation, migration, circuit formation)

• Language, range of movement, and social skills

What is most commonly developed during critical periods of development?

• Brain cell connects (proliferation, migration, circuit formation)

• Language

• Social skills

• Maturation
