Hugely substantial psychological work is being done in tropical zone countries and regions. Journal of Tropical Psychology is specifically circum-global and unites the rapidly growing torrid climate-related nations around the earth in the development and sharing of their psychological discoveries. In addition to the geographical limits of past designated tropical countries, this rapidly expanding torrid or tropical zone could eventually and increasingly include all but the most polar regions. The journal's summary objectives are:

- To share the full range of psychological progress in the growing tropical climate regions
- To disseminate progress in adaptation to the global expansion tropical climates
- To develop an international network of psychologists working in these regions
