What this topic is asking
Topic 3.8 closes Unit 3 by asking what happens after culture diffuses. The College Board wants you to explain the effects of cultural diffusion: how cultures interact through acculturation, assimilation, and syncretism; how societies become multicultural; and the tension between a homogenising global culture and the survival of local identity, including responses such as nativism and cultural revival. The skill is to weigh the outcomes of contact, both the blending and the resistance.
Acculturation, assimilation, and syncretism
The exam's core vocabulary describes degrees of cultural change.
The difference between acculturation and assimilation is one of degree: acculturation keeps some of the original culture; assimilation largely replaces it.
Multiculturalism and a global culture
Diffusion reshapes whole societies, and the exam wants both the blending and its costs.
- Multiculturalism is the coexistence of many cultures within one society, each retaining distinct traits; it is an outcome of migration and diffusion that values diversity.
- A global culture spreads through the contemporary diffusion of Topic 3.6: a dominant culture, often associated with Western or commercial language, media, and products, can spread worldwide.
- The cost is homogenisation and placelessness: as global culture spreads, local languages, customs, and traditions can be displaced, eroding cultural diversity and the distinctive character of places.
How local cultures respond
The topic emphasizes resistance as well as absorption.
These responses show that diffusion does not simply produce one global culture: local identity persists, adapts, and sometimes resists, which connects back to the cultural landscapes of Topic 3.2, where identity is written on the land.
Why this matters for the exam
Effects of diffusion is the payoff of Unit 3, tying together the patterns of Topic 3.3 and the diffusion of Topics 3.4 to 3.7, and it links to the effects of migration in Unit 2. FRQs ask you to contrast acculturation and assimilation, explain the threat of a global culture, or name a form of local resistance, so practice weighing blending against the survival of local identity.
Try this
Q1. Identify whether a group fully losing its original culture as it adopts a dominant one is acculturation or assimilation. [Recall]
- Cue. Assimilation; it is the more complete loss of the original culture, unlike acculturation, which keeps some original traits while adopting the dominant culture.
Q2. Explain how a spreading global culture can threaten local cultures. [Short explanation]
- Cue. Rapid global diffusion spreads a dominant culture of language, media, and products that can displace local languages, customs, and traditions, eroding diversity and producing placelessness.

AP 2018 (style)1 marksA migrant group adopts the language and customs of its new country while keeping some of its own traditions. This blending of cultures is best described as: (A) assimilation. (B) acculturation. (C) nativism. (D) placelessness.Show worked answer →
A stimulus-style multiple choice item. The correct answer is (B).
Acculturation is the process by which a group adopts some traits of a dominant culture while retaining parts of its own, producing a blend. Assimilation (A) is the more complete loss of the original culture as a group fully adopts the dominant one. Nativism (C) is hostility toward immigrants and their culture; placelessness (D) is the loss of distinctive local character.
The exam reward is distinguishing partial blending (acculturation) from complete absorption (assimilation).
AP 2021 (style)3 marksCultural diffusion changes both incoming and host cultures. (A) Describe the difference between acculturation and assimilation. (B) Explain how globalization can threaten local cultures. (C) Explain ONE way local cultures resist or respond to a global culture.Show worked answer →
A 3-point describe-explain FRQ.
(A) Describe (1 point): acculturation is the partial adoption of a dominant culture's traits while keeping some of one's own (a blend); assimilation is the more complete loss of the original culture as a group fully adopts the dominant one.
(B) Explain (1 point): rapid global diffusion spreads a dominant global culture (language, media, products) that can displace local languages, customs, and traditions, eroding cultural diversity and producing placelessness.
(C) Explain (1 point): local cultures resist through revival of language and traditions, multiculturalism, or nativism (movements protecting local identity against outside influence), preserving distinctiveness against homogenisation.
Markers reward a clear acculturation-versus-assimilation contrast, a real threat from globalization, and a genuine form of local response.
