It's been 20+ years since researchers recommended that police videorecord lineups. But no one has empirically tested the diagnostic value of these videos... until now. Here, we provide a compelling case to mandate the videorecording of lineup procedures.

Finding #3: Witnesses' lineup behavior can diagnose high-confidence mistaken identifications. When witnesses are highly confident but their behavior indicates a weak and disfluent recognition experience, the CJS system should doubt their accuracy.

Finding #2: Not only did witness behaviors discriminate between accurate and inaccurate decisions, but they also improved classification performance over and above confidence and decision speed.

Finding #1: Accurate witnesses behaved markedly different than inaccurate witnesses—a strong and fluent recognition experience implied accuracy and a weak and disfluent recognition experience implied inaccuracy.

🚨 New preprint 🚨 Why should police video-record lineups? We videorecorded 1496 witnesses as they completed lineups. We coded the behaviors that these witnesses demonstrated and subjected the resulting data to machine learning analyses. Link and findings below!

Why are lineup rejections less diagnostic of innocence than suspect identifications are of guilt? Take a look at our preprint for insight on this all-too-common finding of the eyewitness id literature.

‼️ Another new preprint ‼️ Here, we find that video recordings of lineup procedures can aid us with diagnosing witness accuracy (over and above confidence and decision time). This project provides even more evidence that the legal system should mandate video recording lineups.

🚨 New preprint available! In this paper, we look at why lineups better inculpate the guilty than they do exculpate the innocent (the rejection-inferiority effect). W/ Andrew Smith, Jim Lampinen, @nydia-ayala.bsky.social, & Ian Dobbins 🔗 www.researchgate.net/publication/...

Very excited to publicly share news about a new tool, Papercheck, that @debruine.bsky.social and me started to develop more than a year ago! In an introductory blog post, we explain our philosophy to automatically check scientific papers for best practices. daniellakens.blogspot.com/2025/06/intr...

Meet the AP-LS Campus Representatives! Today we have Rebecca Ying from Iowa State University's Cognitive Psychology Ph.D. program.

New blog post! In which I explain the issue with mediation analysis and sketch out one way to deal with the underlying causal inference problem -- in just a bit over 1,000 words! If you have never found the time to read up on this, now is your chance. www.the100.ci/2025/03/20/r...

Maya Irvin-Vitela will be presenting this work in the Saturday 3/15 datablitz (5pm-6pm) in San Cristobol. This work is from Ciera Arnett's dissertation (Maya helped as a coder!). Interesting work & findings about psychosis, substance use, & insanity. #APLS2025 #Law #Psychology #PsychLaw #CLJLab

How could AI be used to assess eyewitness identification accuracy? Andrew Smith, @nydia-ayala.bsky.social and @rying.bsky.social discuss three ways AI could prove useful! @officialsarmac.bsky.social #PsychLaw psycnet.apa.org/doi/10.1037/...

🚨 New publication alert! In this paper, we find that the biased-lineup preference effect (or the finding that lay ppl rate IDs from biased lineups as more reliable than those from unbiased lineups) is driven by perceptual fluency. www.researchgate.net/publication/...

So unbelievably excited for the @psychonomicsociety.bsky.social conference later this week! Would love to chat with anyone who comes by my poster Saturday night! Below are all the presentations from my lab this year! We're presenting some really fun stuff- excited to share it with everyone! 😀

This paper is now accepted at JEP:Applied! See updated manuscript here: www.researchgate.net/publication/...

Side note: the witness justification that the classifier rated as "very high likelihood of a correct rejection" for the sequential lineup (pg. 37) still cracks me up

Wanted to share some really cool work! @nydia-ayala.bsky.social, Andrew Smith, & Gary Wells utilized machine learning to evaluate the utility of confidence, decision time, and the language of lineup justifications in the context of sequential & simultaneous lineups! See preprint below ⬇️

If you're interested in getting a PhD in Cognitive Psychology, consider applying to Dr. Andrew Smith's Psych & Law Lab at Iowa State University! We study judgment & decision making in applied contexts (particularly eyewitness identification). See below for links ⬇️

Back when I was an undergrad interested in eyewitness decision making, I looked up to so many amazing people and was terrified approaching them at APLS….. but now I’m beyond thankful to have the chance to work with many of those same people and see their brains work in real time!!
