Final answer:
The domain related to the external conditions that impact a client's day-to-day activities is the Environmental Domain, which includes both physical and social aspects.
Step-by-step explanation:
The domain that refers to the external physical and social conditions surrounding the client and in which the client's daily life occupations occur is the Environmental Domain. This domain encompasses both the physical (abiotic) environment, such as temperature and geography, as well as non-living conditions that can influence behavior and life processes. Furthermore, it also includes the social conditions, which are designed to satisfy the health needs of humans and ecosystems on various levels.
Developmental psychologists consider three primary domains when studying human growth: cognitive, physical, and socio-emotional. Although these domains are crucial for development, the aforementioned Environmental Domain is not one of these specific three.
