The affect associated with negative events fades faster than the affect associated with positive events (the fading affect bias). The fading affect bias is present in most participants and is thought to be evidence of a healthy coping mechanism operating in autobiographical memory. Prior research shows that the fading affect bias can be distorted by negative individual difference variables such as dysphoria and anxiety. The goal of this research is to link the fading affect bias to the positive individual difference variable of Grit. A total of 197 participants completed the short Grit Scale and were divided into four groups based on their Grit scores (i.e., low Grit to high Grit). Participants retrieved positive and negative event memories and then made affect ratings for the events. The results show that increased levels of Grit were associated with a stronger fading affect bias.

The strongest storm in Philippines history, super-typhoon Haiyan, barreled through central Philippines in 2013 and left a high death toll and extensive destruction in its wake. Past studies have investigated Fading Affect Bias (FAB) in extremely negative situations like the death of a loved one and found that the FAB generally occurs in those extreme situations, but this study is the first to assess FAB in first-hand memories for a natural disaster survival situation. The FAB phenomenon is the tendency for emotional intensity associated with negative memories for events to fade over time and emotional intensity for positive events stays relatively stable over time. Researchers collected memories for the super-typhoon from survivors three years after the event. Results showed that negative emotional intensity for the event faded after the event. Emotion in comparison positive memories for non-typhoon events did not fade, and emotion in comparison negative memories faded, following results in several other FAB studies. The Positive and Negative Affect Scale (PANAS) was used as an initial assessment of mood before the study began, and PANAS scores reliably predicted current emotional intensity scores. Memory vividness and emotional intensity in first-hand accounts of a natural disaster experience behave like vividness and intensity in flashbulb memories, but details in first-hand accounts are similar to the amount of details in memories of near-death experiences. How memory rehearsal behaves in relation to time elapsed since event has yet to be captured for first-hand survival experiences.
