“…The precognitive visions (i.e., seeing events occurring in the future), extrasensory perception (i.e., acquisition of information without the use of the five physical senses), and life review are also prototypical NDE features but are less often encountered (Charland-Verville et al, 2014;Greyson, 2003;Zhiying & Jian-xun, 1992). Interestingly, all these features are subsequently recalled with vividness and details, even decades later (Cassol et al, 2019a(Cassol et al, , 2020Martial et al, 2017a;Moore & Greyson, 2017;Thonnard et al, 2013).…”

As interest grows in near-death experiences (NDEs), it is increasingly important to accurately identify them to facilitate empirical research and reproducibility among assessors. We aimed (1) to reassess the psychometric properties of the NDE scale developed by Greyson (1983) and ( 2) to validate the Near-Death Experience Content (NDE-C) scale that quantifies NDEs in a more complete way. Internal consistency, construct and concurrent validity analyses were performed on the NDE scale. Based on those results and the most recent empirical evidence, we then developed a new 20-item scale. Internal consistency, explanatory and confirmatory factor, concurrent and discriminant validity analyses were conducted. Results revealed (1) a series of weaknesses in the NDE scale, (2) a 5-factor structure covering relevant dimensions and the very good psychometric properties of the NDE-C scale, including very good internal consistency (Cronbach α=0.85) and concurrent validity (correlations above 0.76). This new reliable scale should facilitate future research.

“…Our findings supported RM memory theory in that typhoon memories held greater episodic features that pertained to real memories than in everyday positive and negative memories. Since memories of NDEs contain higher amounts of details (especially internal and episodic information; Cassol et al, 2020) than FBMs, we can initially suggest that first-hand survival memories behave more like NDE memories than FBMs. Episodic qualitative phenomenological characteristics of NDE memories especially include contextual and sensorial details (e.g., Moore & Greyson, 2017), as do first-hand survivor accounts of natural disasters.…”

“…NDEs are psychological events that generally occur when people have been close to death or if they have survived situations of intense danger (Greyson, 2000), and classical examples of NDE memories are reported by people after being in a coma or having endured cardiac arrest (Martial et al, 2020). NDEs are first-hand experiences and emotionality and consequentiality (consequences of the event or aftermath; Cassol et al, 2019) are incorporated in people's NDE memories, as well as life impact (Cassol et al, 2020). Thonnard et al (2013) suggested that because NDEs evince both emotion and consequentiality, they could meet the definition of FBM because NDEs are more detailed and long-lasting than other autobiographical memories.…”

“…Emotionally-charged traumatic first-hand events like NDEs evince richer memory narratives over time while richness in FBM narratives decline with time (van Giezen et al., 2005). Memories of NDEs are vivid (e.g., Moore & Greyson, 2017) and contain higher amounts of details (especially internal and episodic information; Cassol et al., 2020) than FBMs. Episodic qualitative phenomenological characteristics of NDE memories include contextual and sensorial details (e.g., Moore & Greyson, 2017) which reflect what one felt or perceived during the event.…”

“…Similarly, shocking memories of first-hand events are rehearsed more frequently than FBMs, in that people think about and talk about them more frequently (Pillemer, 2009). Cassol et al. (2020), using a short Memory Characteristics Questionnaire (sMCQ; D’Argembeau & van der Linden, 2008), found that the sensation of feeling the emotions felt during the event while remembering was significantly higher for NDE and autobiographical memories when compared to FBMs.…”

Remembering the Super-Typhoon: Some, but Not All, Qualities of First-Hand Survivor Memories of Natural Disaster Are Similar to Near Death Experience and Flashbulb Memory Accounts

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.
