    Henderson, E. L., Vallée-Tourangeau, F., & Simons, D. J. (2019). The effect of concrete wording on truth judgements: A preregistered replication and extension of Hansen & Wänke (2010)
    View abstract View full publication
    When you lack the facts, how do you decide what is true and what is not? In the absence of knowledge, we sometimes rely on non-probative information. For example, participants judge concretely worded trivia items as more likely to be true than abstractly worded ones (the linguistic truth effect; Hansen & Wänke, 2010). If minor language differences affect truth judgements, ultimately they could influence more consequential political, legal, health, and interpersonal choices. This Registered Report includes two high-powered replication attempts of Experiment 1 from Hansen and Wänke (2010). Experiment 1a was a dual-site, in-person replication of the linguistic concreteness effect in the original paper-and-pencil format (n = 253, n = 246 in analyses). Experiment 1b replicated the study with an online sample (n = 237,n = 220 in analyses). In Experiment 1a, the effect of concreteness on judgements of truth (Cohen’s dz = 0.08; 95% CI: [–0.03, 0.18]) was smaller than that of the original study. Similarly, in Experiment 1b the effect (Cohen’s dz = 0.11; 95% CI [–0.01, 0.22]) was smaller than that of the original study. Collectively, the pattern of results is inconsistent with that of the original study.
    Ruiz Castro, M., van der Heijden, B. I., & Henderson, E. L. (2020). Catalysts in career transitions: Academic researchers transitioning into sustainable careers in data science
    View abstract View full publication
    Academic careers are becoming less linear and secure, and are increasingly shaped by environmental constraints. As a result, highly qualified early and mid-career researchers, in particular from STEM (Science, Technology, Engineering, and Mathematics) disciplines, are pursuing careers outside academia. This paper advances theory and empirical research on career transitions and sustainable careers by investigating how junior academics transition into the field of data science by exploring the facilitators of their career transition and the ways in which they experience career sustainability in their new occupational field. This study relies on 28 in-depth interviews with early and mid-career STEM researchers from elite universities who decided to join a data science “bootcamp” to pursue a new career as data scientists. Our study reveals the career barriers that junior researchers experience in academia and how  increase their career adaptability, facilitating a career transition into sustainable careers in data science. Our study shows that career sustainability is experienced through the reaffirmation of interviewees' identity as researchers outside of academia as well as in the reconciliation between their previous career expectations and actual career outcomes after transitioning into data science.

    Henderson, E. L., Simons, D. J. & Barr, D. J. (2021). The trajectory of truth: A longitudinal study of the illusory truth effect
    View abstract View full publication
    Repeated statements are rated as subjectively truer than comparable new statements, even though repetition alone provides no new, probative information (the ). Contrary to some theoretical predictions, the illusory truth effect seems to be similar in magnitude for repetitions occurring after minutes or weeks. This Registered Report describes a longitudinal investigation of the illusory truth effect ( = 608,  = 567 analysed) in which we systematically manipulated intersession interval (immediately, one day, one week, and one month) in order to test whether the illusory truth effect is immune to time. Both our hypotheses were supported: We observed an illusory truth effect at all four intervals (overall effect: χ2(1) = 169.91; repeated = 4.52, new = 4.14; H1), with the effect diminishing as delay increased (H2). False information repeated over short timescales might have a greater effect on truth judgements than repetitions over longer timescales. Researchers should consider the implications of the choice of intersession interval when designing future illusory truth effect research.

    View abstract View full publication
    Planning is an everyday activity that is extended in time and space, yet is frequently studied in the absence of interactivity. Successful planning relies on an array of executive functions including self-control. We investigated the effects of interactivity and self-control on planning using a sequential-task paradigm. Half of the participants first completed a video-viewing task requiring self-control of visual attention, whereas the other half completed the same task without the selfcontrol constraint. Next, and within each of these groups, half of the participants manipulated cards to complete their plan (high-interactivity condition); for the other half, plans were made with their hands down (lowinteractivity condition). Planning performance was significantly better in the high- than in the lowinteractivity conditions; however the self-control manipulation had no impact on planning performance. An exploration of individual differences revealed that long-term planning ability and non-planning impulsiveness moderated the impact of interactivity on planning. These findings suggest that interactivity augments working memory resources and planning performance, underscoring the importance of an interactive perspective on planning research.
