A recent study by Neuser and \ncolleagues (2020) provided novel evidence for this process in humans, by reporting a positive effect of transcutaneous auricular vagus nerve stimulation (taVNS) \non the invigoration of reward-seeking behaviors, especially for food rewards. \n\nWe conducted an independent direct replication of Neuser et al. (2020), to assess the \nrobustness of their findings. Following the original study, we used a single-blind, \nsham-controlled, randomized cross-over design. We applied left-sided taVNS in \nhealthy human volunteers (n=40), while they performed an effort allocation task \nin which they had to work for monetary and food rewards. \n\nThe replication study was purely confirmatory in that it strictly followed the analysis plans and scripts used by Neuser et al. Although, in line with Neuser et al., we found strong effects of task variables on effort invigoration and effort maintenance, we failed to replicate their key finding: taVNS did not increase the strength of invigoration \n(p=.62); the data were five times more likely (BF10=0.19) under the null hypothesis. We also found substantial evidence against an effect of taVNS on effort \nmaintenance (p=.50; BF10=0.20). \n\nOur results provide evidence against the idea that left-sided taVNS boosts the motivational drive to work for rewards. Our study also highlights the need for direct replications of influential taVNS studies."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2023"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Social Sciences"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"effort"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"gut-brain"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"HLM"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"reproducibility"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"taVNS"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"tVNS"}}]},{"typeName":"publication","multiple":true,"typeClass":"compound","value":[{"publicationCitation":{"typeName":"publicationCitation","multiple":false,"typeClass":"primitive","value":"Lucchi, F., Lloyd, B., & Nieuwenhuis, S.
