A kindling model refers to a concept in psychology that describes the process of how repeated stimuli can lead to increased sensitivity or reactivity to subsequent stimuli. There are various synonyms for this term, including the sensitization model, the snowball model, and the escalation model. These synonyms all imply a gradual intensification of response to stimuli, with each subsequent exposure increasing the likelihood of an amplified reaction. Other related terms include the threshold model and the tipping point model, which suggest that at a certain point, the cumulative effects of repeated stimuli can trigger a significant and rapid shift in behavior or perception.
