Migration is the movement of people from one location to another, either within a country (internal migration between cities or regions) or between countries (international migration). Migration may be relatively voluntary (e.g., for employment opportunities) or involuntary (e.g., due to armed conflict, persecution, or natural disasters), and it may be temporary (e.g., migrant workers moving back and forth between source and receiving areas) or permanent (e.g., becoming a permanent resident in a new country). The term immigration refers specifically to international migration that is relatively permanent in nature. Immigrants are those individuals who have moved to a new country on a relatively permanent basis. Of importance, refugees are a particular type of immigrant, defined and protected by international law. They are individuals who have been formally recognized as having fled their country of residence because of a well-founded fear of persecution, armed conflict, violence, or war. Until they are recognized as such, these individuals are asylum seekers—individuals who have claimed refugee status and are waiting for that claim to be evaluated. Despite the relative permanence of immigration, advances in transportation and communication mean that immigrants are able to travel to, spend time in, and communicate on a regular basis with their country of origin. As a result, what has been termed transnationalism may result, with individuals holding strong ties with, and actively participating in, both the country of origin and the new receiving country. Migration often results in two or more cultures coming into contact. This contact is especially likely for international migration where immigrants from one national group (the society of origin) come into contact with members of a different national group (the receiving society). Culture may include specific beliefs, attitudes, and customs, as well as values and behaviors. The term acculturation refers to the changes that may occur when individuals from different cultures come into contact, with possible changes in both immigrants and members of the receiving society. Psychological theory and research suggest that acculturation is bidimensional, with changes potentially taking place along two dimensions—one representing the maintenance or loss of the original culture and the other representing the adoption or rejection of the new culture. This bidimensionality is important because it suggests that acculturation is not linear from original culture to new culture, but instead that individuals may simultaneously participate in the new culture and maintain their original culture. The two cultures may be expressed at different times, in different contexts, or may merge to form cultural expressions that have aspects of both cultures. With voluntary and involuntary migration at historically high levels, understanding the drivers of migration and its consequences for migrants and those with whom they come into contact are essential for global cooperation and well-being.

Transnational historiography, which emerged in the 1990s, covers historical phenomena that transcend the boundaries of the nation-state, analyzing the processes of circulation, transformation and hybridization of scientific ideas and practices across national frontiers. When scientific knowledge flows between different countries, the ideas that emerge in one particular national context adapt to the new local contexts of their hosts, with their particular cultural, social, political and scientific traditions. In psychology, the transnational approach provides a productive theoretical framework capable of going beyond the traditional US-centered perspective that has dominated the historiography of psychology since the mid-20th century. This US-based historiography has, for example, interpreted the historical influence of I. P. Pavlov in terms of two main factors: his methodological contribution—the conditioned reflex—and the existence of a behaviorist tradition in the receptor psychology community. However, a more global analysis questions the need for these two elements and, at the same time, offers insights into the conditions that facilitated or hindered the flow of Pavlovian science beyond the United States. Thus, for example, between 1903 and 1970 the dissemination and appropriation of the Pavlovian science of conditioned reflexes took two different routes: in America, scientific aspects and factors dominated; whereas elsewhere, politics prevailed over science. This happened in countries such as China, Cuba, and Spain, with dictatorial regimes at different ends of the political spectrum, where Pavlov’s work arrived under the auspices of government programs to modernize scientific and clinical institutions. Once Pavlov’s ideas had been introduced through reform programs in each country, they were accepted or rejected depending on whether the sign of the regime in question converged with the ideology prevailing in the Soviet Union, which it did in China and Cuba, but not in Spain. In these countries, where psychology did not have strong institutional roots and behaviorism was not a dominant approach, Pavlovian ideas found a receptive audience among health professionals-doctors, psychiatrists, and clinical psychologists - keen to embrace new ideas and treatments for mental disorders. Thus, from a transnational perspective, the global repercussion of Pavlov’s ideas went far beyond the strictly methodological sphere.
