Final answer:
Cognitive psychology encompasses the study of mental processes like perception, memory, and language. Hormones, though related to cognitive functions via neurotransmitters, are not a primary focus of cognitive psychology and more frequently studied in biological psychology.
Step-by-step explanation:
In cognitive psychology, the focus is on the study of how people think, perceive, remember, and use language. The branch of psychology that focuses on the mental processes that underlie these activities is cognitive psychology. Specifically, cognitive psychology examines perception, memory, and language as they relate to our experiences and actions. It is a broad field that often involves interdisciplinary research.
However, among the options provided, hormones are not typically studied directly within cognitive psychology. Instead, they are more commonly associated with biological psychology or endocrinology, which explore how biological processes and substances, including hormones, affect behavior and cognitive functions.
Though hormones can impact cognition and are related to neurotransmitters, which in turn affect cognitive functions, the study of hormones itself is not the primary concern of cognitive psychology.
