Seeing the Crash

Seeing the Crash

How do you replicate a classic experiment when the original materials no longer exist? In this episode of Research as it Happens, Rolf Zwaan talks with Anita Eerland (Radboud University Nijmegen), who leads the visual stimuli team for the project's replication of the famous Loftus and Palmer (1974) study. At first glance, the task seems straightforward: find a suitable traffic accident video. But as the conversation reveals, reconstructing a classic experiment raises a surprising number of questions. What begins as a discussion about finding a crash video gradually becomes a conversation about a deeper question: what exactly are we trying to replicate? The original materials, or the psychological experience they were designed to create? Music written and performed by Rolf Zwaan Comment or question?

In other words

In the previous episode, Elizabeth Loftus reminded us that a single word can influence what people remember. In this episode, we take a deep dive into language and translation. The conversation begins with Steven Verheyen (Erasmus University Rotterdam, Netherlands), who leads the translation effort in our international replication project. We discuss the practical challenges of translating research materials into multiple languages, but also the deeper theoretical questions that emerge in the process. How do you translate words such as hit and smashed? Are we translating words, meanings, or psychological effects? And why should translation be viewed as a genuine scientific contribution rather than a purely technical task? In the second half of the episode, Rolf talks with linguist Maha Godoy (Universidade Federal do Rio Grande do Norte, Natal, Brazil). Together they discuss the Loftus and Palmer study from a linguistic perspective and explore what language can tell us about the mechanisms underlying the misinformation effect. The conversation also turns to the experience of conducting research in Brazil and the similarities and differences between scientific cultures across countries. A recurring theme throughout the episode is that language is not merely a vehicle for communicating research. In a study like Loftus and Palmer, language is part of the phenomenon itself. If a single word can influence memory, then translating that word becomes a scientific challenge in its own right. As the project expands across countries and languages, questions that initially seem practical often reveal deeper theoretical issues. In that sense, translation is not simply something that happens before the research begins—it is one of the ways we learn from the research itself.

Back to the source

In this episode of Research as it Happens, Rolf Zwaan talks with Elizabeth Loftus (University of California, Irvine) about one of the most influential experiments in cognitive psychology: the 1974 Loftus & Palmer study on memory and misinformation. Loftus reflects on how the original study emerged partly by chance—from a lunch conversation with her lawyer cousin and a growing desire to work on questions with clearer real-world relevance. What followed became a landmark demonstration that the wording of a question can influence what people later report remembering. In the conversation, we explore: * how the original experiments were designed and conducted, * what happens to the original memory after misinformation is introduced, * whether the effect reflects overwriting, retrieval interference, or source-monitoring problems, * and how this line of work reshaped theories of memory. We also discuss the current large-scale replication project inspired by the original studies. What aspects of the classic experiment should remain unchanged? Which elements can be modernized? Does it matter if participants watch digital videos on computers rather than projected film clips? Could culturally different vehicles—such as scooters instead of cars—produce similar effects? The episode also touches on a broader issue in replication research: how revisiting classic findings can become more than an attempt to reproduce an effect. Large collaborative projects may also provide opportunities to test alternative explanations and extend the original work in new directions. More than fifty years after the original experiment, the central question remains remarkably current: How much of what we remember is shaped by what happened afterward?

Working Together

In the previous episode, we followed how a simple question about a classic finding in psychology grew into a large international research project. In this episode, we take a closer look at what that shift means in practice. What happens when research moves from a single study to a collaboration involving dozens of labs? How do you organize such a project—and what new challenges emerge along the way? I speak with Katja Pronizius (University of Vienna, Austria), one of the authors of The Advantage of Big Team Science about the structure of big team science, its advantages, and the challenges that come with working at scale. These include issues of coordination, communication across cultures, and the distribution of responsibility within large teams. In the second part of the episode, I talk to Bjørn Sætrevik (University of Bergen, Norway) about what it is like to work inside such a large-scale collaboration. The conversation turns to a question that quickly becomes central in projects like this: how to assign roles and give credit when many people contribute in different ways. Together, these conversations highlight how scaling up research changes not only how studies are conducted, but also how contributions are organized, recognized, and made meaningful. At this stage of the project, labs are still joining and working groups are being formed. The structure of the collaboration is taking shape—and many of the questions discussed in this episode are becoming directly relevant.

Where it starts

In Research as it Happens, we go inside a large-scale psychology project, where labs around the world collaborate to study human memory. Each episode follows the process in real time—how ideas develop, experiments are designed, evidence is evaluated, and how researchers decide what to do next. In this first episode of Research as it Happens, we go back to where the project began. What starts as a simple question—how robust is a well-known finding?—quickly opens up a much larger set of issues about how research is done, how evidence is evaluated, and how scientific knowledge develops over time. The project itself grew out of a conversation between Rolf Zwaan and Anita Eerland about a classic study in psychology: Loftus and Palmer (1974) The study showed that the way a question is phrased can influence what people remember about an event—a finding that has become a staple in psychology textbooks. In this episode: * Rolf talks with Anita Eerland (Radboud University, Nijmegen, Netherlands) about how that initial conversation at the kitchen table developed into a large-scale, international research project that they are now leading. * He also speaks with Massimo Grassi (University of Padua, Italy) about how he uses the Loftus study in his teaching, and what he expects from a project that revisits such a well-established finding. Together, these conversations highlight how even familiar results can raise new questions when examined more closely—and how different researchers bring different perspectives to the same problem. At the time of recording, the project is still in its early stages, with researchers joining from labs around the world and smaller teams forming to develop materials and plan the first studies. This is where it starts. Music written and played by Rolf Zwaan Mentioned in the episode: Target study: Loftus, E. F., & Palmer, J. C. (1974).
