In psychology, there are two types of stimuli. These can be physical or visual. A stimulus is considered weak if it has very little effect on the person’s behavior or response. It is also subthreshold if it fails to produce a threshold response for at least one subject in some experiment.
What is the example of a weak stimuli?
The best way to understand this concept is with an example. First, you should know what a threshold stimulus is. For instance, let’s say that someone tells you “I’m hungry.” That statement might not have any impact on your behavior because you’re just sitting there reading this article without being hungry yourself (most likely). However, if they said “I want to eat,” then that would make your stomach grumble and the craving would be there. In psychology, a threshold stimulus is something that might elicit an observable response or reaction from someone.
Back to our example of a weak stimulus: let’s say you have two people in front of you- one who likes ice cream and another who hates it. If both subjects are told that they can only eat over the next 24 hours but not anything else (like sugar), then individually, we know what each person will do with this restriction because their preferences for food in general define how they’ll react, either they’ll go out of their way to satisfy themselves by eating as much ice cream as possible without succumbing to any negative effects like weight gain or increased blood glucose levels.
