[Solution Description] According to Piaget, infants begin to pursue objects that are partially covered around 8 months of age as they start developing object permanence.

Key Concept: Moral Reasoning Evolution, Cognitive Development Influence

c) It allows consideration of abstract principles

[Solution Description] During adolescence, increased cognitive capabilities allow for abstract thinking and hypothetical-deductive reasoning. These developments enable youths to critically evaluate rules, consider broader ethical principles, and understand the implications of actions beyond immediate consequences. This cognitive growth moves them from rule-based thinking (common in childhood) towards principle-based reasoning characteristic of more advanced stages like the Post-conventional level.

Key Concept: Reflex Disappearance

b) 3-4 months

[Solution Description] The Moro reflex, also known as the startle reflex, is a primitive reflex seen in newborns. It usually disappears when the infant reaches the age of 3-4 months.

Key Concept: Attachment Basics

b) Comfort is crucial for attachment.

[Solution Description] Harlow’s study on attachment demonstrated the importance of comfort in forming strong emotional bonds. In his experiments with monkeys, he found that infant monkeys preferred spending time with a soft, comforting surrogate mother rather than a wire one that provided food. This highlighted the role of physical comfort in the formation of attachment.

Key Concept: Emotional Development

c) Post-conventional

[Solution Description] Kohlberg proposes that individuals develop their own personal moral codes during the stage known as “Post-conventional” morality. This usually occurs in adolescence or adulthood when individuals start internalizing principles based on universal ethical concepts rather than just conforming to societal norms.

Key Concept: Age of Onset

c) 12-13 years

[Solution Description] Boys generally start their growth spurts at ages 12-13, though this can vary due to genetic and environmental factors.

[Solution Description] The definition of gender focuses on the social dimensions, as opposed to “sex,” which refers to the biological attributes distinguishing males and females.

Key Concept: Development Sequence

c) Proximodistal trend

[Solution Description] The principle that describes the pattern of growth where development proceeds from the central part of the body towards the extremities is called the Proximodistal trend. This means that infants first gain control over parts closer to the center, like the torso, before gaining control over the arms.

Key Concept: Animism

a) A child believes their teddy bear feels sad when left alone

[Solution Description] Animism refers to the belief common in young children that inanimate objects have life-like qualities and mental states. For instance, a child believing the moon smiles down at them represents animistic thinking.
