Subjectively, some emotions have a sudden onset, while others build up slowly. For example, a text message from a loved one can quickly fill you with joy. Alternatively, frustration/annoyance at being stuck in traffic can build up over time or watching a funny video can help you transition from sadness to functional calm.
According to various studies, the perceived magnitude of an emotion changes as the time between evaluation and experience grows. Similarly, is there evidence that the onset or acceleration of a built-up emotion is perceived differently at the time between the evaluation and the onset grows?
