Hypothesis
Trauma survivors with a lifetime history of PTSD would show impaired working memory capacity on an emotional reading span task compared to trauma-exposed controls who have never had PTSD.
Conclusion
Individuals with a history of PTSD have significantly greater impairments in emotional working memory capacity compared to those who have never suffered from PTSD.
Supporting Evidence
- Participants with PTSD showed impaired working memory capacity in emotional contexts.
- The study developed a task to measure working memory capacity in emotional contexts.
- Executive deficits in PTSD manifest differently across contexts.
Takeaway
People who have PTSD find it harder to remember things when they are also thinking about their traumatic experiences, compared to people who have never had PTSD.
Methodology
Participants completed an emotional working memory capacity task that required them to remember neutral words while processing sentences related to trauma.
Potential Biases
Potential biases due to the self-report nature of some measures and the limited demographic diversity of the sample.
Limitations
The sample size was limited, and the study did not assess other psychiatric conditions that may affect results.
Participant Demographics
Participants aged 17-65, including those with a lifetime history of PTSD and trauma-exposed controls.
