After an eyewitness completes a lineup, officers are advised to ask witnesses how confident they are in their identification. Although researchers in the lab typically study eyewitness confidence numerically, confidence in the field is primarily gathered verbally. In the current study, we used a natural language-processing approach to develop an automated model to classify verbal eyewitness confidence statements.

- Researchers investigated the effectiveness of debriefing after experiments involving misinformation and memory, finding mixed results in participant endorsement of misinformation.
- In a first study with 373 participants, those who were debriefed after exposure to misinformation reported learning more, but some still retained false information.
- A second study with 439 participants introduced an enhanced debriefing that clearly identified misinformation, which completely eliminated the misinformation effect and improved the overall participant experience compared to traditional debriefing.
Pandemics and infodemics: Research on the effects of misinformation on memory.

On social media and in everyday life, people are often exposed to misinformation. Decades of research have shown that exposure to misinformation can have significant impacts on people's thoughts, actions, and memories. During global pandemics like COVID-19, people are likely exposed to heightened quantities of misinformation as they search for and are exposed to copious amounts of information about the disease and its effects.

- Feedback from lineup administrators can greatly affect how confident witnesses feel about their identifications, especially when misinformation or typical feedback is provided post-identification.
- In two studies with 907 participants, it was found that both types of feedback led to inflated confidence in witness identifications.
- The findings emphasize the importance of properly documenting witness confidence immediately after identification to avoid misleading influences over time.
If I'm Certain, Is It True? Accuracy and Confidence in Eyewitness Memory.

Choice blindness refers to the finding that people can often be misled about their own self-reported choices. However, little research has investigated the more long-term effects of choice blindness. We examined whether people would detect alterations to their own memory reports, and whether such alterations could influence participants' memories.
