Neuroscience focuses on the brain’s structure and the regions that are activated when people engage in various tasks. Cognitive Psychology, on the other hand, focuses on the mind and behavior.

The short answer is that while neuroscience investigates the human mind through the lens of the structure and function of the nervous system, psychology tries to do the same using observations of behavior, cognition, perception, attention, and emotion.

Neuropsychology is focused on in relating psychological functioning to behaviour, while cognitive psychology is more focused on cognitive variables like memory, attention, consciousness. However, both are so related that one can rarely spot a difference between them.

Cognitive psychology is the science in charge of understanding the main processes (mind) that help us to understand our world and neuroscience studies how the brain correlates these processes. Dr Almudena Ortega Segura Gazzaniga, M.S.; Ivri R.B.; Mangun G.R. (2018).

In contrast to cognitive science, which studies memory, language, reasoning, attention, and learning—mental processes—neuroscience investigates the brain from a biological, neurological, and chemical standpoint.
