Institutions of higher learning, such as the University of the West Indies in Trinidad and Tobago, went from offering a few courses in psychology to granting graduate degrees. Individual countries have also established national psychological organizations that partner with the Caribbean Alliance of National Psychological Associations (CANPA) to sponsor biannual conferences. At the other end of the spectrum are countries (e.g., Guyana) with fedging programs that are only now offering basic courses in psychology. In this brief chapter, an attempt is made to provide a glimpse into what we know about some aspects of psychology in the southernmost Caribbean countries of Guyana and Trinidad and Tobago. We begin with a discussion of socio- historical experiences, pertinent sociodemographic factors, family dynamics, and religious practices of different ethnic groups in the two countries, before turning our attention to key mental health challenges, human resources, training programs in psychology at tertiary institutions of learning, and psychological organizations.
