Addition is a speech error in which linguistic material is added.
In psychology, "addition" can refer to the process of adding something to a situation or condition. Addition can be physical, such as adding a new stimulus or condition to an experiment, or it can be psychological, such as adding a new thought or emotion to a mental state. Here are a few examples of how "addition" might be used in the field of psychology:
-
Experimental manipulations: In experimental research, researchers may use addition as a way of manipulating a variable in order to examine its effects. For example, a researcher might add a new stimulus to an experiment to see how it influences behavior.
-
Cognitive processes: Researchers may study the effects of addition on cognitive processes, such as memory or problem-solving. For example, a researcher might study how the addition of a new piece of information affects an individual's ability to recall a list of items.
-
Emotional states: Researchers may study the effects of addition on emotional states, such as how the addition of a positive or negative emotion influences behavior. For example, a researcher might study how the addition of anxiety affects an individual's performance on a task.
-
Social interactions: Researchers may study the effects of addition on social interactions, such as how the addition of a new group member influences group dynamics.
