Researchers' perspectives on preregistration in animal research

Preregistration is arguably one of the most promising and impactful Open Science practices. Defined as the a priori registration of study designs and analysis plans, preregistration has long been established as standard practice in clinical human research and is increasingly taken up in other fields of science. Despite growing evidence suggesting that preregistration can mitigate questionable research practices, and the existence of two platforms targeting animal studies, preregistration remains uncommon in animal research. In light of the reproducibility crisis and calls for more transparency and rigor also in animal research, preregistration represents a potentially promising step forward. However, implementing such policies without understanding their impact carries potential risks. It is, therefore, essential to uncover the strengths, weaknesses, opportunities, and threats of preregistration before advancing its implementation in animal research. This current study addressed this need as part of a larger feasibility project on preregistration of animal experiments in Switzerland, and aimed to: 1) assess the researchers experiences with preregistration; 2) examine their attitudes, subjective norms, perceived behavioral control, intentions, motivations, and perceived obstacles regarding preregistration; 3) explore associations between these psychosocial constructs and relevant background characteristics; 4) identify perceived facilitators and barriers to preregistration; and 5) summarize researchers suggestions for improving preregistration. A preregistered cross-sectional online survey was conducted among all registered study directors of ongoing animal experiments in Switzerland. Of the 1,385 invited study directors, 418 completed the survey (30.2% return rate; 41% female; age M = 47.1, SD = 9.52). Among them, 39.2% had never heard of preregistration, and only 10% had preregistered studies before participating in the survey. Bureaucratic burden (77.6%), time costs (71.4%), and low flexibility (65.7%) were the most common reported barriers to preregistration. On average, participants described rather unfavorable attitudes towards preregistration, negative subjective norms, relatively low perceived behavioral control, weak intention, and limited motivation to preregister, along with high perceived obstacles. Participants who had never preregistered a study, as well as those with more research experience, showed more negative scores on all assessed psychosocial constructs related to preregistration. Our findings offer guidance on promising measures to enhance acceptance of preregistration among animal researchers, including raising awareness, offering education and training, and facilitating procedures, to enhance the acceptance of preregistration among animal researchers.

Decoding the content of working memory in school-aged children

Developmental improvements in working memory (WM) maintenance predict many real-world outcomes, including educational attainment. It is thus critical to understand which WM mechanisms support these behavioral improvements, and how WM maintenance strategies might change through development. One challenge is that specific WM neural mechanisms cannot easily be measured behaviorally, especially in a child population. However, new multivariate decoding techniques have been designed, primarily in adult populations, that can sensitively decode the contents of WM. The goal of this study was to deploy multivariate decoding techniques known to decode memory representations in adults to decode the contents of WM in children. We created a simple computerized WM game for children, in which children maintained different categories of information (visual, spatial or verbal). We collected electroencephalography (EEG) data from 20 children (7-12-year-olds) while they played the game. Using Multivariate Pattern Analysis (MVPA) on childrens EEG signals, we reliably decoded the category of the maintained information during the sensory and maintenance period. Across exploratory reliability and validity analyses, we examined the robustness of these results when trained on less data, and how these patterns generalized within individuals throughout the testing session. Furthermore, these results matched theory-based predictions of WM across individuals and across ages. Our proof-of-concept study proposes a direct and age-appropriate potential alternative to exclusively behavioral WM maintenance measures in children. Our study demonstrates the utility of MVPA to measure and track the uninstructed representational content of childrens WM. Future research could use our technique to investigate childrens WM maintenance and strategies.
