Raj V Jain, Sridharan Devarajan · COSYNE 2025
Our experiences from the recent past, even if no longer relevant, can powerfully shape our current choices. Such “serial dependence” has been observed ubiquitously in various cognitive phenomena [1]. Recent work suggests a causal role of the PPC in mediating serial dependence in rodents [2]; similar evidence in humans is correlative at best [3]. Does the PPC causally mediate serial dependence in humans? We analyzed data from participants (n=26) performing a spatially cued change detection task [4]. Participant received either 40-Hz transcranial alternating current stimulation (tACS) over the
