The negative look stops the behavior in the short run. So it is punished I think, but at the same time punishment is not known for being a long standing solution. As in the behavior will stop for a short time until Esperanza expects it.
In summary it will lose its power of stopping the behavior once expected.
But that is simply a guess.
If you are looking for an overall explanation.
Rationale:
+reinforce --> no bc it is not increasing the behavior.
- reinforcement is when something is removed that increases the behavior, I think.
- punishment is something out side of the situation.
- such as Pavlov non connected
- yes it is threatening, but that may not explain the behavior connection?
-I would verify this with research, but apparently that is against the rules?
