John W. Berry

His first area of research examines how cultural groups and their individual members adapt their customs and behaviours to the ecological contexts in which they have developed and now live. This perspective has been captured in his development of the ecocultural perspective, which seeks to explain how individuals develop and acquire their behavioural repertoire in various ecological contexts and cultures. This perspective links the habitat of a cultural group to their social institutions and practices (such as their settlement style, social stratification, and socialisation practices), and thence to the development of a variety of behaviours of individual members of these cultural groups (including perception, cognition and social behaviours). The focus of much of this research has been with indigenous peoples in Africa, the Arctic and Asia, contrasting groups with hunting, agricultural and urban life styles.  He has published research books on this topic between 1976 and 2017.  In carrying out this work, the use of the comparative method has been central. This method has required the development of the concepts of imposed etic, emic, and derived etic as ways to identify the methods used when making cross-cultural comparisons.

He has examined the psychology of acculturation and intercultural relations, and has developed the concepts of acculturation strategies and acculturative stress. The concept of acculturation strategies refers to some different ways for how groups and individuals seek to live together, using the four concepts of integration (engaging both cultures), assimilation or separation (engaging only one or the other culture) and marginalisation (engaging neither culture). The outcomes of these ways of intercultural living have been described in terms of three forms of adaptation:  psychological wellbeing; sociocultural competence; and intercultural relations. The concept of acculturative stress was developed as an alternative to culture shock; this concept uses the stress, coping and adaptation framework to describe the challenges encountered during the acculturation process.  He has published research books dealing with these issues between 1977 and 2017. He is much involved in the application of research findings in both of these areas to the development of policies and programmes in the domains of education, immigration, multiculturalism and wellbeing.

He has sought to integrate and consolidate both cross-cultural and intercultural psychology by participating in the production of textbooks (between 1990 and 2011) and handbooks (between 1980 and 2016). Some of these have been translated into Chinese, Greek, Indonesian, Italian, Japanese, Korean, Russian and Turkish. Most recently he has co-edited a 4 volume compendium of classic and current articles in cross-cultural psychology (2017).

In addition to these books, with colleagues he has published over 120 journal articles and 200 book chapters.

For this work he is highly cited in the literature, with over 92,000 citations, and an h index of 110 on Google Scholar.[2]
