Abstract: Consumer acculturation refers to the adaptation of immigrant consumers to the consumer environment in the host country. In this paper, the author develops a cognitive model to explore the learning process underlying consumer acculturation. Based on the Adaptive Control of Thought (ACT*) Theory, the model proposes that knowledge about consuming in the host country is first acquired in the form of declarative knowledge. This declarative knowledge is then used interpretively through general problem-solving skills. Knowledge compilation further incorporates such declarative knowledge into new productions, which allow consumers to solve consumption-related problems more efficiently. Important research propositions are derived from the model.
