<h3>A primary reinforcer is what?</h3>
The elements that affect human learning and behavior have long been the subject of research by behavioral psychologists. In this area of research, learning is linked to classical and operant conditioning as well as the relationship between inputs and outcomes. Stimuli are signs or events in the environment that can elicit feelings and behaviors in both people and animals. For instance, if someone has positive associations with the aroma of pizza, the aroma of freshly baked pizza may tempt them to eat that particular sort of food. In the same way that smelling spoiled or unappetizing food can make someone feel sick, it can also cause them to avoid a specific region.
These illustrations demonstrate how associations people make between components of their environment and specific outcomes can have an impact on their behavior.
Operant conditioning is a type of learning in which a specific action's results influence whether or not that action is repeated in subsequent situations. Operant conditioning can be used to teach new behaviors by employing incentives and penalties to reinforce and correct behavior. For instance, by providing rewards that would encourage or reinforce particular behaviors, some animals can be trained to follow straightforward commands.
Consequently, a natural response to a stimulus is referred to as a primary reinforcer.

Answer: Unemployment insurance decreases frictional unemployment.
Explanation:
FRICTIONAL UNEMPLOYMENT
This is unemployment caused by people moving from one job to another. It is temporary and is part of the natural rate of unemployment.
Unemployment insurance does not reduce unemployment because to get unemployment insurance you have to be just that, unemployed. An unemployed person getting unemployment insurance is still unemployed.
Perhaps more concerning is that unemployment insurance might actually increase frictional unemployment. With people getting Unemployment Insurance they might take longer finding a job that they 'feel' suits them, in other words they become selective because they have a financial cushion to fall back on.
I think it was because we really don't know what exactly happened in the past.
Also, I'm pretty sure people did not keep track of colored people back then.
