What is "attachment" in developmental psychology?

A: A child's preference for toys over people

B: The deep emotional bond that forms between a baby and their primary caregiver

C: The process of learning to walk and talk

D: The tendency for children to copy their parents' behaviour

Correct: The deep emotional bond that forms between a baby and their primary caregiver

Attachment is the strong emotional bond that develops between infants and their primary caregivers — usually parents. Psychologist John Bowlby argued that this bond evolved because it kept vulnerable infants close to protective adults. A secure attachment — where the caregiver is consistently responsive — gives children a "safe base" from which to explore the world, and is associated with better emotional and social outcomes throughout life.

According to Jean Piaget, young children (under about 2 years old) don't yet understand that objects still exist when they're out of sight. What is this concept called?

A: Object permanence

B: Conservation

C: Egocentrism

D: Assimilation

Correct: Object permanence

Object permanence is the understanding that objects continue to exist even when they are not visible. Piaget found that infants under about 8 months old will not search for a hidden object — out of sight really does seem to mean out of mind. This is why peek-a-boo is so exciting for very young babies: the return of a face is genuinely surprising. By around 18–24 months, most children have fully developed object permanence.

Adolescence (the teenage years) is a time of significant brain development, not just hormonal change.

Answer: True

Adolescence involves major changes in the brain, not just the body. The prefrontal cortex — responsible for decision-making, impulse control, and weighing long-term consequences — is still maturing throughout the teenage years and into the mid-twenties. Meanwhile, the reward centres of the brain are highly active, making adolescents more sensitive to pleasure and peer approval. This imbalance helps explain why teenagers tend to take more risks and be more influenced by peers than adults.

What did developmental psychologist Lev Vygotsky mean by the "zone of proximal development"?

A: The age at which children begin to talk

B: The physical space where learning happens most effectively

C: The gap between what a child can do alone and what they can do with guidance

D: The period just before a child reaches a developmental milestone

Correct: The gap between what a child can do alone and what they can do with guidance

Vygotsky's zone of proximal development (ZPD) describes the sweet spot of learning: the tasks a child cannot yet do independently but can accomplish with support from a more skilled person — a teacher, parent, or older peer. Effective teaching targets this zone. Too easy, and there's no growth. Too hard, and the child is overwhelmed. The ZPD underpins ideas like scaffolding — gradually withdrawing support as the child becomes more capable.

Human development essentially stops once we reach adulthood.

Answer: False

Development continues across the entire lifespan — in adulthood and old age as well as childhood. Erik Erikson's theory of psychosocial development describes stages from birth to death, each involving a different challenge (such as developing intimacy in early adulthood, or finding meaning and purpose in later life). Cognitive abilities, relationships, values, and identity continue to evolve throughout life.

Research on early childhood consistently shows that which factor has the strongest positive impact on a child's development?

A: Exposing children to educational toys from birth

B: Warm, consistent, responsive caregiving from a trusted adult

C: Starting formal education as early as possible

D: Limiting screen time to zero in the first two years

Correct: Warm, consistent, responsive caregiving from a trusted adult

The most important factor in healthy child development is the quality of the relationship with a primary caregiver. Secure attachment — provided by consistent, sensitive, responsive caregiving — builds the foundation for emotional regulation, social skills, language, and resilience. No amount of enrichment toys or early academic instruction can substitute for the basic human experience of feeling safe, seen, and responded to by a caring adult.
