Assignment 4 semester 2 Answers

### Question 1
**What are the three fundamental characteristics of human development?**
**Answer:** The three fundamental characteristics are: (1) Nature and Nurture - the
interplay between genetic inheritance and environmental influences; (2) Continuity and
Discontinuity - whether development is gradual and cumulative or occurs in distinct
stages; and (3) Universal and Context-Specific Development - the balance between
common developmental patterns across cultures and unique cultural variations.
**Rationale:** These three characteristics form the foundational framework for
understanding all aspects of human development. They represent the core debates that
developmental psychologists grapple with when studying how people change and
remain the same over time.

### Question 2
**Define developmental psychology.**
**Answer:** Developmental psychology is the scientific study of human development
over the entire life span, from conception to death.
**Rationale:** This definition distinguishes developmental psychology from other
subfields by emphasizing the lifelong nature of development, rather than focusing only
on childhood.

### Question 3
**What are the four interactive forces that shape human development?**
**Answer:** The four interactive forces are: (1) Biological forces - genetic, neurological,
and physiological factors; (2) Psychological forces - cognitive, emotional, and
personality factors; (3) Sociocultural forces - interpersonal, societal, cultural, and ethnic
factors; and (4) Life-cycle forces - the timing of events and experiences across the
lifespan.
**Rationale:** These forces do not operate in isolation. Understanding how they interact
provides a comprehensive framework for analyzing development.

### Question 4
**How do normative and non-normative influences determine developmental
outcomes?**
**Answer:** Normative influences are events that most people experience at similar
times (e.g., puberty, starting school), while non-normative influences are unique events
that happen to specific individuals (e.g., winning a lottery, experiencing a traumatic
accident).
**Rationale:** Both types of influences shape individual development trajectories.
Normative influences provide predictability, while non-normative influences create
individual differences.

### Question 5
, **What is the difference between continuity and discontinuity in development?**
**Answer:** Continuity views development as a gradual, cumulative process where
changes are quantitative (e.g., growing taller). Discontinuity views development as
occurring in distinct stages with qualitative changes (e.g., Piaget's stages of cognitive
development).
**Rationale:** This distinction influences how researchers study development and how
interventions are designed.

### Question 6
**Who proposed the psychosocial stages of development, and how many stages are
there?**
**Answer:** Erik Erikson proposed eight psychosocial stages of development, each
characterized by a specific crisis or conflict that must be resolved.
**Rationale:** Erikson's theory expanded Freud's psychosexual theory to include social
and cultural factors across the entire lifespan.
