Explanation: Behaviourism in psychology is a theory that deals with the study and explanation of human and animal behaviour. In doing so, the behaviour is conditioned by certain stimuli, whether positive or negative, so reinforcements, depending on whether a particular behaviour wants to be amplified, i. e favoured or wants to be eliminated. Thus, these reinforcements are set by the conditioner of behaviour, that is, reinforcements from the environment. And these reinforcements influence behaviour in accordance with the expectation on the part of those who condition certain behaviours with particular stimuli.

On the other hand, cognitive psychology is a psychological branch that deals with the study of mental processes, that is, the processing of information during observation and an event, responding to that event as a stimulus, and responding to the event by processing the information by remembering, perceiving, etc. These processes are all those that take place in the mind set, such as perception, language, memory, attention, thinking, the ability to create something, problem solving, and this is especially refer to the internal mental processes / events that occur between stimuli, that is, sensory responses due to a stimulus and specific behaviour as a reflection / reaction to that stimulus. One example is learning, where learning is done through observation, that is, observing something and adopting facts about it, perceiving it etc. There are different levels of development of these cognitive abilities.
