Online Now: Looking into working memory through micro eye movements
dlvr.it
Looking into working memory through micro eye movements
Understanding how humans select, rehearse, and transform internal representations ‘in mind’ is vital. Gaining access to these latent working-memory processes, however, is not trivial. Here, I review the recent discovery that working-memory processes ‘leak’ into spatial biases in minuscule eye movements known as microsaccades. I first unpack this central finding and position it alongside complementary findings from the literature on attention, memory, and eye movements. Next, I adopt a pragmatic perspective, showcasing how microsaccade biases can be leveraged as a versatile signal to ‘track’ working-memory processes, with benefits that complement traditional brain-imaging approaches. Finally, I outline opportunities and future avenues opened by this recently exposed and remarkably reliable association between externally accessible micro eye movements and internal working-memory processes.
